Continuous glucose monitoring (CGM) has revolutionised diabetes care, with proven effect on glycaemic control, adverse diabetic events (such as hypoglycaemia and diabetic ketoacidosis) and hospitalisations in the general population. However, the evidence for CGM in older people is less robust.

We conducted a narrative review of trials reporting data comparing standard blood glucose monitoring (SBGM) and CGM in adults over 65 with type 1 or type 2 diabetes who were treated with insulin published between 1999 and 2024.

Seventeen studies were identified, including eight retrospective cohort studies and five randomised controlled trials (RCTs). Sixteen of the 17 papers were based in Europe or North America. The studies were highly heterogeneous; however, they provided clear evidence supporting the use of CGM in reducing hypoglycemia in older adults, with potential benefits for overall wellbeing and quality of life..

Current approaches to diabetes care in older adults may over-rely on HbA1c (haemoglobin A1c) as a measurement of control given accuracy may be reduced in older adults and propensity for hypoglycaemia. Although goals should be personalised, avoidance of hypoglycaemia is a key goal for many older people with diabetes. There is good evidence that CGM can improve time-in-range and reduce hypoglycaemia and glucose variability in older adults. CGM should be considered for older adults as a means of reducing hypoglycaemia and associated potential harm.

This study aimed to investigate the effects of glycaemic control and diabetes distress on frailty in older Chinese patients with diabetes, and to explore the mediating role of diabetes distress between glycaemic control and frailty.

This is a descriptive, cross-sectional study. A total of 209 older patients with diabetes were recruited from a teaching hospital in Zhejiang Province. Data were collected from February to September 2022.

A self-designed questionnaire was used to collect demographic and disease-related data. The Fried Scale and Diabetes Distress Scale were employed to assess frailty and diabetes distress, respectively The bootstrap method was used to examine the mediating effects of diabetes distress on glycaemic control and frailty. The STROBE checklist was adhered to in the reporting of this study (see details in File S1).

The findings indicated a positive correlation between the level of glycaemic control and frailty, as well as between diabetes distress and frailty. Furthermore, diabetes distress was found to play a complete mediating role between glycaemic control and frailty.

The study findings highlight the relationship between glycaemic control, diabetes distress and frailty offering a valuable reference for enhancing the management of frailty in older patients with diabetes.

This study emphasizes the significance of managing glycaemic control and diabetes distress in older patients with diabetes to prevent frailty, and may contribute for healthcare professionals to developing effective measures to improve the frailty of older diabetic patients in clinical settings.

This study was conducted with the participation of older patients with diabetes who contributed data by completing study questionnaires and undergoing physical assessments.

To investigate the association between prediabetes, frailty, and the risk of myocardial infarction (MI), stroke, heart failure (HF), and all-cause mortality in the oldest old.

A nationwide retrospective cohort study of individuals aged 80+ classified as prediabetic (HbA1c 5.7%-6.4% or impaired fasting glucose 100-125 mg/dL) or normoglycemic during two baseline periods (2005-2006 and 2014-2015) and follow-up (2007-2013 and 2016-2022). Frailty was assessed using the cumulative deficit method.

Among 126,323 participants (61.4% females, mean age 84.1 ± 3.7 years), 34,151 (27.0%) were classified as persons with prediabetes and 92,172 (73.0%) as normoglycemic at baseline. Over seven years, 13.5% progressed to diabetes, 47.4% regressed to normoglycemia, and 39.1% remained with prediabetes. Non-frail individuals were more likely to progress to diabetes than the severely frail (15.0% vs. 9.3%). Prediabetes was associated with lower all-cause mortality (HR 0.86, 95% CI 0.85-0.88) but not MI (HR 0.98, 95% CI 0.94-1.02), while it was associated with increased risks of HF (HR 1.06, 95% CI 1.03-1.09) and stroke (HR 1.06, 95% CI 1.02-1.10).

In the oldest old (aged 80+), prediabetes is associated with reduced all-cause mortality but slightly increased risks of HF and stroke. Frailty modulates prediabetes progression, with non-frail individuals more likely to develop diabetes.

The use of continuous glucose monitoring (CGM) and automated insulin delivery (AID) technologies can improve patient outcomes and overall quality of life while helping to reduce the long-term costs. However, current eligibility criteria imposed by many major commercial insurers limit access to these technologies among a large portion of the diabetes population. This narrative review and commentary highlights the evidence supporting the use of CGM and AID in the various diabetes populations, discuss the current eligibility criteria that make these technologies inaccessible to individuals who would benefit, and present recommendations for modifying these criteria.

Hypoglycaemia is a common cause of presentation to the emergency department (ED) for people with diabetes mellitus. Patients experiencing a hypoglycaemic episode require prompt treatment with fast-acting glucose to prevent brain fuel deprivation and functional brain failure, therefore it is vital that ED nurses can recognise the signs and symptoms of hypoglycaemia and are aware of the factors that can compound or mask it. This article discusses the aetiology and signs and symptoms of hypoglycaemia in adults with type 1 and type 2 diabetes and describes the use of an algorithm for the management of hypoglycaemia in this patient population in hospital. The author also discusses how ED nurses can try to identify the cause of the hypoglycaemic episode and work with patients, their relatives or carers and the wider multidisciplinary team to prevent reoccurrence.

Continuous glucose monitoring (CGM) may improve self-management and reduce hypoglycemia risk among individuals with diabetes. However, little is known about how older adults with insulin-treated type 2 diabetes (T2D) experience and incorporate this technology into their daily lives.

To explore experiences, preferences, barriers, and questions related to using CGM among older adults with insulin-treated T2D with and without experience using CGM.

Qualitative focus group study.

English-speaking older adults with T2D in a large, integrated healthcare delivery system. Groups included either experienced CGM users or adults who had not previously used CGM. Recruitment efforts prioritized individuals ≥ 75 years of age.

Transcripts were analyzed using the Framework Method to identify perspectives on CGM. Specific thematic categories were hypoglycemia-related benefits, general benefits, usefulness and ease of use concerns, and CGM questions.

The study included 26 participants: 17 (65%) were experienced CGM users, 58% were female; median age was 74 (range 62-88) years. Participants perceived and anticipated these CGM benefits: informing behavior changes, reducing in-the-moment hypoglycemia risk, improving awareness and decision-making, and strengthening clinician collaboration. Perceived CGM barriers included challenges with wearability and reliability, burdens to others, distrust of technology, sensory and learning challenges, insufficient clinician support or engagement, and access and payer hurdles. Despite these downsides, experienced users perceived CGM as a worthwhile alternative to daily fingerstick glucose checks. Non-users were able to formulate many usability questions, providing a snapshot of informational needs for this age group.

Older adults with insulin-treated T2D experienced or anticipated benefits from CGM for diabetes management. Findings indicate a need for tailored education and self-management support for older adults to learn and gain maximal benefit from this technology.

Prevalence of type 2 diabetes increases with age. Both the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) promote the enrollment of older patients to randomized controlled trials (RCTs) in diabetes. The objective of this study was to assess the eligibility criteria limiting the inclusion of older adults to RCTs in type 2 diabetes.

This cross-sectional analysis of ClinicalTrials.gov included phase 2, 3 and 4 RCTs of drugs and biologicals, with enrollment ≥100, registered at ClinicalTrials.gov and started from 2014 through 2023.

A total of 278/594 (46.8%) trials had a limit of 90 years of age or less (primary outcome). The odds of the age limits were higher in RCTs funded from non-commercial sources (adjusted odds ratio (aOR), 2.83, 95% confidence interval (CI), 1.77-4.52; p < 0.001) and phase 2 trials (aOR, 2.38; 95% CI, 1.49-3.81; p < 0.001). A total of 542/594 (91.2%) trials had other relevant exclusion criteria, mostly those concerning comorbidities common in older patients (secondary outcome). However, none of the RCTs excluded patients with frailty which is a key factor determining the prognosis of older patients with diabetes. Only two trials enrolled solely older persons.

Most RCTs in type 2 diabetes have the eligibility criteria limiting the enrollment of older patients. The age limits should be eliminated and patients should be excluded based on scientifically justified criteria especially those concerning comorbidities and frailty. Moreover, the benefits and harms of new drugs in older patients with multimorbidity and/or frailty should be assessed in dedicated phase 4 trials.

Ultra-rapid-acting insulin analogs (URAA) are a further development and refinement of rapid-acting insulin analogs. Because of their adapted formulation, URAA provide an even faster pharmacokinetics and thus an accelerated onset of insulin action than conventional rapid-acting insulin analogs, allowing for a more physiologic delivery of exogenously applied insulin. Clinical trials have confirmed the superiority of URAA in controlling postprandial glucose excursions, with a safety profile that is comparable to the rapid-acting insulins. Consequently, many individuals with diabetes mellitus may benefit from URAA in terms of prandial glycemic control. Unfortunately, there are only few available recommendations from authoritative sources for use of URAA in clinical practice. Therefore, this expert consensus report aims to define populations of people with diabetes mellitus for whom URAA may be beneficial and to provide health care professionals with concrete, practical recommendations on how best to use URAA in this context.

Diabetes mellitus is the second leading cause of death in South Africa, and almost 90,000 people died from diabetes-related causes in the year 2019. This study aimed to investigate facilitators that can be harnessed to strengthen community actions and barriers that should be redressed in structured public health and health promotion programs for people with diabetes mellitus at a primary healthcare level.

An exploratory qualitative study was conducted using face-to-face interviews among 20 conveniently sampled participants. The Ottawa Charter was adopted to guide health promotion and strengthening actions for people with diabetes mellitus. This study was conducted at Ngangelizwe Community Health Centre. Ngangelizwe is one of the townships located about 2 km east of Mthatha Town in the Eastern Cape Province of South Africa. The thematic analysis method was used to analyse data with the assistance of Atlas ti, version 23 software.

Five overarching themes were yielded and categorized as facilitators and barriers. Facilitators included enhancing the role of community healthcare workers and strengthening health education activities. Barriers included lack of support groups, food insecurity, and unavailability of community health promotion programs.

We conclude that a collaborative health promotion intervention with the necessary competencies should be designed to assess needs and develop, implement, and evaluate relevant empowerment programs at the household and community levels. This approach involves active engagement with health promoters/ public health practitioners and community health workers at the local level, allowing individuals and communities to access motivation and knowledge regarding the control of diabetes mellitus.

We evaluated the effectiveness of a community diabetes specialist nurse (cDSN) working with district nurses (DNs) to optimise insulin therapy on DN workload and patient outcomes.

This was an observational clinical improvement study of outcomes pre- and post-introduction of an intervention within a community diabetes service in an areas of England. Patients were followed up for 6 months. The intervention was a cDSN providing advice and support to DNs in safe diabetes management, with a particular focus on insulin use.

in total, 148 of 224 patients were reviewed; 130 (87.8 %) were available for follow up 6 months after their first review. Comparing pre- to post-intervention outcomes, number of patients with a hypoglycaemic event reduced from 21/129 to 1/128 (X2 = 19.71, p < 0.001) as did the number with a hyperglycaemic event; 53/129 to 23/128 (X2 = 16.48, p < 0.001). Number of DN visits and use of acute hospital services also improved significantly. Estimated cost savings through reduced DN visits, insulin usage, and hospital service use totalled £1.9 million.

Significant financial savings and reduced patient harms were identified following our intervention in this cohort. Roll-out to other sites in England is a next step.

In recent years, sodium-glucose co-transporter 2 inhibitors (SGLT2i) have emerged as a valuable treatment for type 2 diabetes (T2D) and heart failure. Despite these medications seeming to be safe in older people, the literature about SGLT2i and frailty is still limited. This study aims to evaluate whether SGLT2i use is associated with increased survival in older adults and if frailty can affect the findings.

We enrolled over 65 patients admitted to the Geriatrics Wards at the University Hospital 'P. Giaccone' in Palermo, Italy, between December 2022 and May 2023. After 12 months of follow-up, various outcomes were assessed, including mortality, hospitalization, glycemic dysregulation, urinary tract infections, and falls. The association between SGLT2i use and mortality was analyzed and reported as hazard ratios (HRs) with their 95% confidence intervals (CIs).

A total of 80 patients were included in the study (mean age 79.5 ± 8.5 years; 50% were women). Patients using SGLT2i had a higher prevalence of T2D (p = 0.02) and cirrhosis (p = 0.001). After adjusting for potential confounders, SGLT2i use was significantly associated with a reduced mortality risk (HR = 0.53; 95% CI: 0.20-0.93; p = 0.02). When stratified by the presence of multidimensional frailty, SGLT2i use was significantly associated with a lower risk of mortality in frail patients (HR = 0.27; 95% CI: 0.06-0.88; p = 0.008), but not in robust ones.

In older frail patients, the use of SGLT2i is associated with reduced mortality after 12 months of follow-up. Further larger studies are needed to evaluate the role of these medications in older adults.

This study aimed to explore the association between admission HbA1c and the risk of 1-year vascular outcomes stratified by age group in patients with acute ischemic stroke (AIS) and diabetes mellitus (DM).

This study analyzed prospective multicenter data from patients with AIS and DM. Admission HbA1C were categorized as:≤6.0%, 6.1%-7.0%, 7.1%-8.0%, and >8.0%. Age was analyzed in categories:≤55 years, 56-65 years, 66-75 years, 76-85 years, and >85 years. The primary outcome was 1-year composite of stroke, MI, and all-cause mortality. The modifying effect of age on the relationships between HbA1c and 1-year primary outcome was explored by Cox proportional hazards model.

A total of 16,077 patients (age 69.0 ± 12.4 years; 59.4% males) were analyzed in this study. Among patients ≤55 years, the hazard ratio (HR) of the 1-year primary outcomes increased with an HbA1C > 8.0% (adjusted HR 1.39[1.13-1.70]). For patients aged 56-65 and 66-75, the highest HRs were observed for an HbA1c of 7.1-8.0% (aHRs; 1.21 [1.01-1.46] and 1.22 [1.05-1.41], respectively). In the 85+ age group, the highest HR occurred for HbA1c ≤ 6.0% (aHR 1.47 [0.98-2.19]). The HbA1c 8.0% showed evident age-dependent heterogeneity in the post hoc HR plots.

Our study revealed that in patients with AIS and diabetes under 55, higher admission hbA1c was associated with an increased risk of the 1-year primary outcome, while in patients aged over 85, lower HbA1c value (≤6.0%) may be associated with an increased risk of vascular events. The results of our study suggest the age-stratified, heterogeneous associations between admission HbA1c and 1-year vascular outcomes in patients with AIS and diabetes.

Evidence on the association of dynamic change in frailty index (FI) with risk of all-cause mortality in the older Chinese population is limited. This study aimed to explore the association of 3-year change in FI with risk of all-cause mortality in an older Chinese population.

We analyzed the data of 4969 participants from the Chinese Longitudinal Healthy Longevity Survey. The primary outcome was all-cause mortality, which was a binary variable and defined as completed data and censored data. Cox proportional-hazard models were used to assess the association of 3-year change in FI with risk of all-cause mortality by using hazard ratios (HRs) and 95% confidence intervals (CIs). Subgroup analyses were conducted to explore the association of 3-year change in FI with risk of all-cause mortality. Additionally, a restricted cubic spline analysis was also conducted to describe the dose-response association.

During a median of 4.08 years of follow-up, deaths were observed in 1388 participants. We observed a 1.27-fold higher risk of all-cause mortality with increase in FI ≥ 0.045 versus change in FI < 0.015 (HR = 2.27, 95% CI: 1.89-2.73). Similar significant associations were observed in the subgroup analyses by age, sex, and residence at baseline. Additionally, a nonlinear dose-response association of 3-year change in FI with risk of all-cause mortality was observed (P overall < 0.001 and P nonlinear < 0.001).

Excessive increase in FI was positively associated with an increased risk for all-cause mortality. Approaches to reducing FI may be of great significance in improving the health of older Chinese individuals.

In older adults with type 2 diabetes (T2DM), tight glycaemic control (HbA1c 7%) can result in more harm than benefit, especially when using insulin or sulfonylureas. Older adults are at higher risk for adverse drug events, especially hypoglycaemia, which may cause falls, confusion and hospitalisations. This Therapeutic Letter evaluates the risks of tight glycaemic control in older adults with T2DM, focusing on deprescribing diabetes medications in those over 65, especially those with multimorbidity and polypharmacy. It assesses the evidence from clinical trials and guidelines, with a focus on preventing hypoglycaemia and improving patient-centred care through relaxed HbA1c targets. Large randomised controlled trials show that intensive glycaemic control (HbA1c ≤ 7%) does not reduce cardiovascular risk, but increases hypoglycaemia and mortality, particularly in older adults. Instead, glycaemic targets should be adjusted based on the patient's overall health and life expectancy. Deprescribing may be considered, starting with drugs most likely to cause hypoglycaemia (sulfonylureas or insulin). Regular reassessment and patient involvement in creating individualised treatment plans are essential.

When switching from premixed insulin to insulin degludec/aspart (IDegAsp), IDegAsp usually starts at the same dose as the premixed insulin according to limited clinical experience or at a dose according to clinician discretion. The dose of insulin degludec used in the real world after switching has been poorly investigated.

A retrospective analysis was conducted on patients with type 2 diabetes who switched from premixed insulin to IDegAsp from October 2016 to December 2023. Repeated measures analysis of variance was used to compare changes in insulin dose, glycated hemoglobin (HbA1c), fasting blood glucose (FBG), and postprandial blood glucose (PBG) before and after switching.

Sixty-six patients with prior low-ratio premixed insulin and 22 with prior mid-ratio premixed insulin were included. Among the low-ratio insulin users, the total daily dose of insulin degludec (IDeg) decreased by 21.43% and 19.05% at 3 and 6 months, respectively, after switching, compared with prior basal insulin dose (both p < 0.001). Conversely, among mid-ratio insulin users, the IDeg daily dose increased by 10.71% and 32.14% at 3 and 6 months, respectively, after switching, compared with prior basal insulin dose (both p < 0.001). In all patients, HbA1c levels decreased by 0.70%, FBG decreased by 1.00 mmol/l, and PBG decreased by 1.61 mmol/l after 6 months of switching (all p < 0.05); the total daily insulin dose and injection frequency significantly decreased after switching (both p < 0.05); age and disease duration did not affect IDegAsp effects on HbA1c reduction.

In the setting of transition to IDegAsp from premixed insulin, the dose of basal insulin in the premixed formulation can be a valuable reference for adjusting insulin degludec dose. IDegAsp is superior to premixed insulin in blood glucose control with reduced total daily dose and injection frequency. IDegAsp could be the best choice for the management of diabetes in elderly patients.

Severe hypoglycemia is a serious adverse drug event associated with hypoglycemia-prone medications; older patients with diabetes are particularly at high risk. Economic food insecurity (food insecurity due to financial limitations) is a known risk factor for hypoglycemia; however, less is known about physical food insecurity (due to difficulty cooking or shopping for food), which may increase with age, and its association with hypoglycemia.

Study associations between food insecurity and severe hypoglycemia.

Survey based cross-sectional study.

Survey responses were collected in 2019 from 1,164 older (≥ 65 years) patients with type 2 diabetes treated with insulin or sulfonylureas.

Risk ratios (RR) for economic and physical food insecurity associated with self-reported severe hypoglycemia (low blood glucose requiring assistance) adjusted for age, financial strain, HbA1c, Charlson comorbidity score and frailty. Self-reported reasons for hypoglycemia endorsed by respondents.

Food insecurity was reported by 12.3% of the respondents; of whom 38.4% reported economic food insecurity only, 21.1% physical food insecurity only and 40.5% both. Economic food insecurity and physical food insecurity were strongly associated with severe hypoglycemia (RR = 4.3; p = 0.02 and RR = 4.4; p = 0.002, respectively). Missed meals ("skipped meals, not eating enough or waiting too long to eat") was the dominant reason (77.5%) given for hypoglycemia.

Hypoglycemia prevention efforts among older patients with diabetes using hypoglycemia-prone medications should address food insecurity. Standard food insecurity questions, which are used to identify economic food insecurity, will fail to identify patients who have physical food insecurity only.

Over the past two decades there has been a substantial rise in the adoption of diabetes therapeutic technology among children, adolescents and younger adults with type 1 diabetes, and its use is now also advocated for older individuals. Older people with diabetes are more prone to experience hypoglycaemia because of numerous predisposing factors and are at higher risk of hypoglycaemic events requiring third-party assistance as well as other adverse sequelae. Hypoglycaemia may also have long-term consequences, including cognitive impairment, frailty and disability. Diabetes in older people is often characterised by marked glucose variability related to age-associated changes such as variable appetite and levels of physical activity, comorbidities and polypharmacotherapy. Preventing hypoglycaemia and mitigating glucose excursions may have considerable positive impacts on physical and cognitive function and general well-being and may even prevent or improve frailty. Technology for older people includes continuous glucose monitoring systems, insulin pumps, automated insulin delivery systems and smart insulin pens. Clinical trials and real-world studies have shown that older people with diabetes benefit from technology in terms of glucose management, reductions in hypoglycaemic events, emergency department attendance and hospital admissions, and improvement in quality of life. However, ageing may bring physical impairments and other challenges that hinder the use of technology. Healthcare professionals should identify older adults with diabetes who may benefit from therapeutic technology and then adopt an individualised approach to education and follow-up for individuals and their caregivers. Future research should explore the impact of diabetes technology on outcomes relevant to older people with diabetes.

Objectives: With the increasing prevalence of diabetes and frailty among older adults, there is an urgent need for precision medicine that incorporates comprehensive geriatric assessments, including frailty detection. This scoping review aims to map and synthesize the available evidence on validated tools for detecting pre-frailty and frailty in community-dwelling elderly individuals with diabetes and outpatient diabetes patients. Specifically, it addresses: (1) What validated tools are available for detecting pre-frailty and frailty in this population? (2) How are these tools associated with outcomes such as glycemic control, hypoglycemia, and metabolic phenotypes? (3) What gaps exist in the literature regarding these tools? Methods: The review followed PRISMA-ScR guidelines, conducting a systematic search across PubMed, Cochrane Library, and Web of Science. The inclusion criteria focused on studies involving individuals aged 70 years and older with diabetes, emphasizing tools with predictive capacity for disability and mortality. Results: Eight instruments met the inclusion criteria, including the Frailty Index, Physical Frailty Phenotype, and Clinical Frailty Scale. These tools varied in domains such as physical, psychological, and social aspects of frailty and their association with glycemic control, hypoglycemia, and metabolic phenotypes. The review identified significant gaps in predicting diabetes-related complications and their clinical application. Conclusions: Routine management of older adults with diabetes should incorporate frailty detection, as it is crucial for their overall health. Although widely used, the reviewed tools require refinement to address the unique characteristics of this population. Developing tailored instruments will enhance precision medicine, leading to more effective, individualized interventions for elderly individuals with diabetes.

This study aimed to find the optimal intervention available to both control blood glucose and improve physical function in the geriatric population with T2DM.

A systemic review and network meta-analysis (NMA) was conducted to assess and rank the comparative efficacy of different interventions on glycosylated hemoglobin A1c (HbAc1), fasting blood glucose (FBG), muscle mass, grip strength, gait speed, lower body muscle strength, and dynamic balance. A total of eight databases were searched for eligible randomized controlled trials (RCTs) that the elderly aged more than 60 years or with mean age ≥ 55 years, the minimal duration of the RCT intervention was 6 weeks, and those lacking data about glycemic level and at least one indicator of physical performance were excluded. The Cochrane risk of bias tool was used to assess the bias of each study included. Bayesian NMA was performed as the main results, the Bayesian meta regression and the frequentist NMA as sensitivity analysis.

Of the 2266 literature retrieved, 27 RCTs with a total of 2289 older adults were included. Health management provided by health workers exerts beneficial effects that is superior to other interventions at achieving glycemic control, but less marked improvement in physical performance. Exercise combined with cognitive training showed more pronounced improvement in muscle strength, gait speed, and dynamic balance, but ranked behind in decreasing the HbAc1 and FBG.

Personalized health management combined with physical and cognitive training might be the optimal intervention to both accomplish glycemic control and improvement of physical performance. Further RCTs are needed to validate and assess the confidence of our results from this NMA.

Background: Frailty is a clinical syndrome prevalent among the elderly, characterised by a decline in physiological reserves and increased susceptibility to stressors, resulting in higher morbidity and mortality. Diabetes and hypertension are common in frail older individuals, often leading to polypharmacy. In this narrative review, we aimed to evaluate the relationship between frailty, diabetes, and hypertension and to identify effective management strategies and future research directions. Methods: This narrative review was conducted using the Scopus, Medline, PubMed, Cochrane Library, and Google Scholar databases. Results: Frailty significantly impacts the management and prognosis of diabetes and hypertension, which, in turn, affects the progression of frailty. Managing these conditions often involves multiple drugs to achieve strict glycaemic control and blood pressure targets, leading to polypharmacy and associated morbidities, including orthostatic hypotension, falls, fractures, hypoglycaemia, and reduced medication adherence. Identifying frailty and implementing strategies like deprescribing can mitigate the adverse effects of polypharmacy and improve outcomes and quality of life. Despite the availability of effective tools for identifying frailty, many frail individuals continue to be exposed to complex treatment regimens for diabetes and hypertension, leading to increased hospital admissions, morbidity, and mortality. Conclusions: Managing diabetes and hypertension in the frail ageing population requires a multidisciplinary approach involving hospital and community geriatricians and pharmacists. This is important due to the lack of sufficient clinical trials dedicated to diabetes and hypertension in the context of frailty. Future large population studies are needed to assess the best approaches for managing diabetes and hypertension in frail individuals.

The prevalence of type 2 diabetes (DM) has been increasing globally, particularly among older adults who are more susceptible to DM-related complications. Elderly individuals with diabetes are at higher risk of developing hypoglycemia compared with younger diabetes patients. Hypoglycemia in elderly patients can result in serious consequences such as cognitive changes, increased risk of falls, heart and other vascular problems, and even high mortality rate.

To assess prevalence, and factors associated with hypoglycemia events among geriatric outpatients with type 2 diabetes mellitus.

The study was conducted at King Abdullah University Hospital (KAUH) at the outpatient diabetes clinic from October 1st, 2022 to August 1st, 2023. Variables such as socio-demographics, medication history, and comorbidities were obtained using electronic medical records. The prevalence of hypoglycemia was determined through patient interviews during their clinic visit. Patients were prospectively monitored for hospital admissions, emergency department visits, and mortality using electronic medical records over a three-month follow-up period. Logistic regression models were conducted to identify factors associated with hypoglycemia and hospital admissions/ emergency visits. Ethical Approval (Reference # 53/151/2022) was obtained on 19/9/2022.

Electronic medical charts of 640 patients who have type 2 diabetes mellitus and age ≥ 60 years were evaluated. The mean age ± SD was 67.19 (± 5.69) years. Hypoglycemia incidents with different severity levels were prevalent in 21.7% (n = 139) of the patients. Insulin administration was significantly associated with more hypoglycemic events compared to other antidiabetic medication. Patients with liver diseases had a significantly higher risk of hypoglycemia, with odds 7.43 times higher than patients without liver diseases. Patients with dyslipidemia also had a higher risk of hypoglycemia (odd ratio = 1.87). Regression analysis revealed that hypoglycemia and educational level were significant predictors for hospital admission and emergency department (ER) visits. Hypoglycemia was a positive predictor, meaning it increased the odds of these outcomes, while having a college degree or higher was associated with reduced odds of hospital admission and ER visits.

Current study identified a considerable prevalence of hypoglycemia among older patients with type 2 diabetes, particularly, among those with concurrent liver diseases and dyslipidemia. Furthermore, hypoglycemia was associated with an increased rate of emergency department visits and hospital admissions by 2 folds in this population.

Despite the availability of new classes of glucose-lowering drugs that improve glycaemic levels and minimise long-term complications, at least 20-25% of people with type 2 diabetes require insulin therapy. Moreover, a substantial proportion of these individuals do not achieve adequate metabolic control following insulin initiation. This is due to several factors: therapeutic inertia, fear of hypoglycaemia and/or weight gain, poor communication, complexity of insulin titration, and the number of injections needed, with the associated reduced adherence to insulin therapy. Once-weekly insulins provide a unique opportunity to simplify basal insulin therapy and to allow good glycaemic control with a low risk of hypoglycaemia. Several approaches to developing a stable and effective once-weekly insulin have been proposed, but, to date, insulin icodec and basal insulin Fc (insulin efsitora alfa) are the only two formulations for which clinical studies have been reported. The results of Phase I and II studies emphasise both efficacy (in term of glucose levels) and potential risks and adverse events. Phase III studies involving insulin icodec are reassuring regarding the risk of hypoglycaemia compared with daily basal insulin analogues. Despite some concerns raised in ongoing clinical trials, the available data suggest that weekly insulins may also be an option for individuals with type 1 diabetes, especially when adherence is suboptimal. For the first time there is an opportunity to make an important breakthrough in basal insulin therapy, particularly in people with type 2 diabetes, and to improve not only the quality of life of people with diabetes, but also the practice of diabetologists.

The increasing burden of type 2 diabetes (T2D), in relation to alarming rise in the prevalence; challenges in the diagnosis, prevention, and treatment; as well as the substantial impact of disease on longevity and quality of life, is a major concern in healthcare worldwide. Sulfonylureas (SUs) have been a cornerstone of T2D pharmacotherapy for over 60 years as oral antidiabetic drugs (OADs), while the newer generation SUs, such as gliclazide modified release (MR), are known to be associated with low risk of hypoglycemia in addition to the cardiovascular neutrality. This scoping review aimed to specifically address the current position of gliclazide MR among other SUs in the contemporary treatment paradigm for T2D and to provide a practical guidance document to assist clinicians in using gliclazide MR in real-life clinical practice. The main topics addressed in this paper include the role of early and sustained glycemic control and use of SUs in T2D management, the properties of gliclazide MR in relation to its effectiveness and safety, the use of gliclazide therapy in special populations, and the place of SUs as a class and gliclazide MR specifically in the current T2D treatment algorithm.

We aimed to investigate the relationship between lifestyle status and metabolic syndrome (MetS) components across gender and age groups of the older population, specifically focusing on identifying the association between MetS and lifestyle factors in classified age groups in older individuals.

Overall, 582 older people with MetS in Yazd (Iran) urban primary health care centers were randomly included from 10 health centers and invited to participate in the study in 2022. During the phone invitation, eligible interested people were asked to refer to health care centers for clinical assessments by trained health researchers. MetS components, dietary intakes using validated frequency food questionnaire, and physical activity by International physical activity questionnaire (IPAQ-short form) were measured.

Women with Mets under 75 yr had significantly higher BMI, weight, and FBS than men and men had significantly higher WC than women. Among patients over 75 yr old, women had significantly higher weight than men had and lower WC and lower HDL_C than men. There were significant differences between gender groups of the aging patient under 75 yr old in terms of vigorous physical activity, total metabolic equivalent of activity, total fat intake, PUFA, and sodium intake, with men reporting level of mentioned lifestyle factors than women.

There were significant gender differences between two aged groups (>75 and <75 yr old) of patients for MetS components and lifestyle risk factors. Weight and WC showed noteworthy gender differences, with variations in both age groups.

There is a rising prevalence of type 2 diabetes among older people. This population also suffers from co-morbidity and a greater number of diabetes related complications, such as visual and cognitive impairment, which can potentially affect their ability to manage insulin regimens. Understanding the experiences of older people when they transition to insulin will help the development of healthcare interventions to enhance their diabetes outcomes, overall health and quality of life.

The aims of this exploratory study were to (1) understand the experiences of older people with type 2 diabetes in relation to insulin treatment initiation and management and (2) use this understanding to consider how the insulin management support provided to older people by healthcare providers could be more tailored to their needs.

A qualitative study using semi structured (remote) interviews with older people with diabetes (n = 10) and caregivers (n = 4) from the UK. Interviews were audio recorded and transcribed, and framework analysis was used to analyse the data.

Three main themes, along with six subthemes, were generated from the study data. Participants generally felt at ease with insulin administration following training, yet some reported feelings of failure at transitioning to insulin use. Participants were also frustrated at what they perceived were insufficient resources for effective self-management, coupled with a lack of professional interest in optimising their health as older people. Some also expressed dissatisfaction regarding the brevity of their consultations, inconsistent information from different healthcare professionals and poor treatment coordination between primary and secondary care.

Overall, the study emphasised that older people need better support, education and resources to help manage their insulin use. Healthcare professionals should be encouraged to adopt a more individualised approach to supporting older people that acknowledges their prior knowledge, physical and psychological capabilities and motivation for diabetes self-management. In addition, better communication between different services and greater access to specialist support is clearly needed for this older population.

An integrated care pathway for insulin use in older people could be considered. This would include an assessment of the older person's needs and capacity on their initiation to insulin; targeted education and training in self-management; timely access to appropriate emotional and peer support resources; care plans developed collaboratively with patients; and individualised glucose targets that recognise the needs and preferences of the older person.

Although we have learned much about how the brain fuels its functions over the last decades, there remains much still to discover in an organ that is so complex. This article lays out major gaps in our knowledge of interrelationships between brain metabolism and brain function, including biochemical, cellular, and subcellular aspects of functional metabolism and its imaging in adult brain, as well as during development, aging, and disease. The focus is on unknowns in metabolism of major brain substrates and associated transporters, the roles of insulin and of lipid droplets, the emerging role of metabolism in microglia, mysteries about the major brain cofactor and signaling molecule NAD+, as well as unsolved problems underlying brain metabolism in pathologies such as traumatic brain injury, epilepsy, and metabolic downregulation during hibernation. It describes our current level of understanding of these facets of brain energy metabolism as well as a roadmap for future research.

Insulin resistance (IR) and cardiovascular diseases (CVD) are relevant concerns in the elderly population; as the world's population ages, IR and CVD are two universal public health problems. While a link between IR a CVD has been established, the mediating mechanisms are uncertain and rigorous investigations are needed to fully elucidate them. The study aimed at assessing the relationship between epicardial fat (EF), an indicator of cardiovascular risk, and IR in Italian free-living elderly (n = 89). Baseline data from a previous cohort was used. Anthropometric measurements, EF, and IR-related variables, including the HOMA-IR index and other biochemical parameters were obtained. The correlation between EF and IR was explored. Further analysis was conducted to identify significant differences regarding IR variables among EF quartiles. EF correlated positively with glucose levels in females, males and the total population. The pairwise comparison among EF quartiles showed significant differences in glucose levels, HOMA-IR index, triglycerides, and total cholesterol levels. To our knowledge, this is the only study assessing the relationship between EF and IR in healthy elderly, while most of the studies have investigated EF and IR in diseased populations. Further research with a longitudinal approach should be conducted to design concrete conclusions about this relationship.

Acromegaly is a rare disorder characterized by excessive production of growth hormone (GH) from a pituitary tumor, typically leading to elevated glucose levels due to increased insulin resistance; hypoglycemia is rare. However, the long-term effect of excess GH on the peripheral organs is still unclear. Here we present a 69-year-old man evaluated for the cause of a hypoglycemic episode. He was underweight (body mass index: 17.3 kg/m2) with sarcopenia, which potentially contributed to his hypoglycemia. Notably, he exhibited progressed proliferative diabetic retinopathy compared to other microvascular complications, leading to further endocrinological investigation. As a result, he was diagnosed with acromegaly showing elevated GH and insulin-like growth factor-1 (IGF-1) with a pituitary tumor. Opting against transsphenoidal surgery (TSS), the patient was treated with a somatostatin analog (SSA), achieving normalized IGF-1 levels with a monthly 120 mg lanreotide injection. In this case, acromegaly could lead to sarcopenia from GH-derived gluconeogenesis in the peripheral organs such as the reduction of muscle leading to reduced glucose reserves. Acromegaly in the elderly may present atypicality. Clinicians should be vigilant for unique manifestations such as advanced diabetic retinopathy, even in elderly patients with hypoglycemia.

This study investigated the characteristics associated with an increased risk of hypoglycemia, in elderly patients with type 1 diabetes mellitus (T1D) using automated insulin delivery (AID) systems.

Cross-sectional observational study including patients >60 years, using sensor-augmented insulin pump therapy with predictive low-glucose management (SAPT-PLGM), hybrid closed-loop (HCL), and advanced hybrid closed-loop (AHCL), for more than three months. A geriatric assessment was performed, and body composition was determined to investigate its association with achieving time below range (TBR) <70 mg/dL goals.

The study included 59 patients (47.5% of men, mean age of 67.6 years, glycated hemoglobin [HbA1c] of 7.5 ± 0.6%, time in range (TIR) 77.8 ± 9.9%). Time below range <70 and <54 mg/dL were 2.2 ± 2.3% and 0.4 ± 0.81%, respectively. Patients with elevated TBR <70 mg/dL (>1%) had higher HbA1c levels, lower TIR, elevated time above range (TAR), and high glycemic variability. Regarding body composition, greater muscle mass, grip strength, and visceral fat were associated with a lower TBR <70 mg/dL. These factors were independent of the type of technology used, but TIR was higher when using AHCL systems compared with SAPT-PLGM and HCL systems.

In elderly patients treated with AID systems with good functional status, lower lean mass, lower grip strength, and lower visceral fat percentage were associated with TBR greater than 1%, regardless of the device used. A similar finding along was found with CGM indicators such as higher HbA1c levels, lower TIR, higher TAR, and higher CV. Geriatric assessment is crucial for personalizing patient management.

To assess the efficacy and safety of iGlarLixi in older people (≥65 years) with type 2 diabetes (T2D) advancing or switching from oral agents, a glucagon-like peptide-1 receptor agonist (GLP-1RA), or basal insulin.

The data of participants aged <65 years and ≥65 years from four LixiLan trials (LixiLan-O, LixiLan-G, LixiLan-L, SoliMix) were evaluated over 26 or 30 weeks.

Participants aged <65/≥65 years (n = 1039/n = 497) had a mean baseline body mass index of 31.4 and 30.7 kg/m2 and glycated haemoglobin (HbA1c) concentration of 66 mmol/mol (8.2%) and 65 mmol/mol (8.1%), respectively. Least squares mean HbA1c change from baseline to end of treatment (EOT) was -14.32 mmol/mol (-1.31%) (95% confidence interval [CI] -14.97, -13.77 [-1.37%, -1.26%]) for those aged <65 years and -13.66 mmol/mol (-1.25%) (95% CI -14.54, -12.79 [-1.33%, -1.17%]) for those aged ≥65 years. At EOT, achievement of HbA1c targets was similar between the group aged <65 years and the group aged ≥65 years: <53 mmol/mol (<7%) (59.0% and 56.5%, respectively), <59 mmol/mol (<7.5%) (75.5% and 73.0%, respectively) and <64 mmol/mol (<8%) (83.8% and 84.1%, respectively). The incidence and event rate of American Diabetes Association Level 1 hypoglycaemia during the studies were also comparable between the two groups: 26.7% and 28.2% and 1.7 and 2.1 events per patient-year for the group aged <65 years and the group aged ≥65 years, respectively. A clinically relevant reduction in HbA1c (>1% from baseline for HbA1c ≥64 mmol/mol [≥8%] or ≥0.5% from baseline for HbA1c <64 mmol/mol [<8%]) without hypoglycaemia was attained by 50.0% and 47.6% of participants aged <65 years and ≥65 years, respectively. Adverse events were similar between the two age groups.

iGlarLixi is a simple, well-tolerated, once-daily alternative for treatment advancement in older people with T2D that provides significant improvements in glycaemic control without increasing hypoglycaemia risk, thus reducing the treatment burden.

The community deintensification rates in older people with diabetes are low and hospital admission presents an opportunity for medication review. We audited the inpatient assessment and deintensification rate in people with diabetes and frailty. We also identified factors associated with adverse inpatient outcomes.

A retrospective review of electronic charts was conducted in all people with diabetes and clinical frailty score ≥6 who were discharged from the medical unit in 2022. Data on demographics, comorbidities and background glucose-lowering medications were collected.

Six-hundred-and-sixty-five people with diabetes and moderate/severe frailty were included in our analysis. For people with no HbA1c in the last six months preceding admission, only 9.0% had it assessed during inpatient. Deintensification rates were 19.1%. Factors that were associated with adverse inpatient outcomes included inpatient hypoglycaemia, non-White ethnicity, and being overtreated (HbA1c <7.0% [53 mmol/mol] with any glucose-lowering medication).

The assessment and deintensification rate in secondary care for people with diabetes and frailty is low. Inpatient hypoglycaemia, non-White ethnicity, and overtreatment are important factors in determining inpatient outcomes highlighting the importance of deintensification and the need for an evidence-based risk stratification tool.

Overtreatment with glucose-lowering treatment (GLT) is frequent and a source of high morbidity and mortality in older adults with type 2 diabetes mellitus (T2DM). This study aimed to identify and synthesize barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM.

Systematic review of qualitative and mixed-methods studies.

Older adults with T2DM, any participants [patients, health care providers (HCPs), caregivers], any settings.

Two researchers (and a referred third researcher at all stages) independently screened original articles reporting qualitative and mixed-methods studies exploring barriers and enablers for deprescribing GLT in older adults published during 2010-2023, identified from MEDLINE, Embase, CINAHL, and gray literature. Quality of the included studies was assessed with the Mixed-Methods Appraisal Tool. Verbatim statements on barriers and enablers were extracted, and determinants of behaviors were identified with the Theoretical Domains Framework (TDF) version 2, and related intervention functions (targets for future interventions) were proposed according to the Behavior Change Wheel (BCW).

We identified only 4 studies from 2 countries (United States and the Netherlands), all recently published (2019-2023), that primarily reported barriers to GLT deprescribing from interviews or focus groups of patients or HCPs practicing outpatient medicine. Knowledge, fear, poor communication, inertia, and trust with HCPs were the main determinants of behaviors that influenced deprescribing, and education, training, persuasion and environmental restructuring were the main intervention functions for proposing future interventions. Studies did not cover financial aspects, physician characteristics, or caregiver and family viewpoints.

The use of a behavioral theory and a validated implementation framework provided a comprehensive approach to identifying barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM. The behavioral determinants identified may be useful in tailoring interventions to improve the implementation of GLT deprescribing in older adults in ambulatory settings.

To characterize sliding-scale insulin (SSI) use in US nursing homes (NHs) before and after the COVID-19 pandemic.

Cross-sectional study.

A total of 129,829 US NH residents on SSI (01/2018-06/2022) across 12 NH chains with a common electronic health record system.

Among all residents with at least 1 administration of SSI documented in the electronic medication administration record, we described resident demographics, frequency of SSI monotherapy vs combination therapy with another diabetes medication, number of daily capillary blood glucose readings ("fingersticks"), and hypoglycemia (capillary blood glucose <70 mg/dL) and hyperglycemia after first SSI use. We used interrupted time series analysis (ITS) with segmented linear regression models to examine whether the monthly prevalence of SSI use changed at and after the onset of the COVID-19 pandemic (March 2020).

There were 129,829 unique NH residents with SSI use [51% women, average age 71.3 (SD 11.7) years]. Of these, 36% of residents received SSI monotherapy and 64% received SSI combination therapy. Residents on SSI received an average of 3.96 (SD 1.41) fingersticks per day. Overall, 26% of SSI users experienced a hypoglycemic event within 30 days of the first SSI dose. The ITS analysis identified a step decrease in the rate of SSI use following the onset of the COVID-19 pandemic (43 fewer SSI users per 1000 insulin users) but no change in overall trend over time from before the onset of the pandemic.

SSI use and fingerstick burden are high in NH residents. Hypoglycemia occurred commonly among residents on SSI. Future research should compare the safety and effectiveness of SSI monotherapy vs other diabetes medication regimens to guide person-centered prescribing decisions in NHs.

With the deepening of aging in China, the prevalence of diabetes in older people has increased noticeably, and standardized diabetes management is critical for improving clinical outcomes of diabetes in older people. In 2021, the National Center of Gerontology, Chinese Society of Geriatrics, and Diabetes Professional Committee of Chinese Aging Well Association organized experts to write the first guideline for diabetes diagnosis and treatment in older people in China, the Guideline for the Management of Diabetes Mellitus in the Elderly in China (2021 Edition). The guideline emphasizes that older patients with diabetes are a highly heterogeneous group requiring comprehensive assessment and stratified and individualized management strategies. The guideline proposes simple treatments and de-intensified treatment strategies for older patients with diabetes. This edition of the guideline provides clinicians with practical and operable clinical guidance, thus greatly contributing to the comprehensive and full-cycle standardized management of older patients with diabetes in China and promoting the extensive development of clinical and basic research on diabetes in older people and related fields. In the past 3 years, evidence-based medicine for older patients with diabetes and related fields has further advanced, and new treatment concepts, drugs, and technologies have been developed. The guideline editorial committee promptly updated the first edition of the guideline and compiled the Guideline for the Management of Diabetes Mellitus in the Elderly in China (2024 Edition). More precise management paths for older patients with diabetes are proposed, for achieving continued standardization of the management of older Chinese patients with diabetes and improving their clinical outcomes.

Cancer survivors are vulnerable to frailty. While few studies have focused on the association of frailty with mortality risk among cancer survivors, the current study aimed to reveal this association. In this cohort study, 4723 cancer survivors were enrolled from the National Health and Nutrition Examination Surveys (NHANES, 1999-2018). Frailty status was quantified using the 53-item frailty index. Death outcomes were linked to National Death Index mortality data (as of December 31, 2019). Cox proportional hazard models were used to estimate HRs (95% CIs). The median (IQR) frailty score was 0.190 (0.132, 0.277). During the median follow-up of 6.7 years, 1775 all-cause deaths (including 581 cancer deaths and 385 cardiac deaths) were documented. Compared to the lowest tertile of frailty scores, the adjusted HRs (95% CIs) for the highest tertile were 2.698 (2.224, 3.272) for all-cause mortality (P trend < 0.001), 2.145 (1.547, 2.973) for cancer mortality (P trend < 0.001), and 3.735 (2.231, 6.251) for cardiac mortality (P trend < 0.001). Moreover, a positive dose‒response association between the frailty score and mortality risk was determined. Each per-unit increase in the frailty score (natural logarithm transformed) was found to increase all-cause mortality by 159% (P < 0.001), cancer mortality by 103% (P < 0.001), and cardiac mortality by 256% (P < 0.001). A consistent result was shown when stratifying by age, sex, race, body mass index, and type of cancer. This study suggested that the frailty index was positively associated with all-cause mortality and cause-specific mortality (including cancer and cardiac deaths) among cancer survivors.

Severe hypoglycemia is associated with adverse clinical outcomes. We evaluated the risk of severe hypoglycemia in older adults initiating newer glucose-lowering medications overall and across strata of known indicators of high hypoglycemia risk.

We conducted a comparative-effectiveness cohort study of older adults aged >65 years with type 2 diabetes initiating sodium-glucose cotransporter 2 inhibitors (SGLT2i) versus dipeptidyl peptidase-4 inhibitors (DPP-4i) or SGLT2i versus glucagon-like peptide-1 receptor agonists (GLP-1RA) using Medicare claims (3/2013-12/2018) and Medicare-linked-electronic health records. We identified severe hypoglycemia requiring emergency or inpatient visits using validated algorithms. After 1:1 propensity score matching, we estimated hazard ratios (HR) and rate differences (RD) per 1,000 person-years. Analyses were stratified by baseline insulin, sulfonylurea, cardiovascular disease (CVD), chronic kidney disease (CKD), and frailty.

Over a median follow-up of 7 (interquartile range: 4-16) months, SGLT2i was associated with a reduced risk of hypoglycemia versus DPP-4i (HR 0.75 [0.68, 0.83]; RD -3.21 [-4.29, -2.12]), and versus GLP-1RA (HR 0.90 [0.82, 0.98]; RD -1.33 [-2.44, -0.23]). RD for SGLT2i versus DPP-4i was larger in patients using baseline insulin than in those not, although HRs were similar. In patients using baseline sulfonylurea, the risk of hypoglycemia was lower in SGLT2i versus DPP-4i (HR 0.57 [0.49, 0.65], RD -6.80 [-8.43, -5.16]), while the association was near-null in those without baseline sulfonylurea. Results stratified by baseline CVD, CKD and frailty were similar to the overall cohort findings. Findings for the GLP-1RA comparison were similar.

SGLT2i was associated with a lower hypoglycemia risk versus incretin-based medications, with larger associations in patients using baseline insulin or sulfonylurea.

In older adults with type 2 diabetes (T2D), overtreatment with hypoglycaemic drugs (HDs: sulfonylureas, glinides and/or insulins) is frequent and associated with increased 1-year mortality. Deintensification of HD is thus a key issue, for which evidence is though limited. The primary objective of this study will be to estimate the effect of deintensifying HD on clinical outcomes (hospital admission or death) within 3 months in older adults (≥75 years) with T2D.

We will emulate with real-world data a target trial, within The Health Improvement Network cohort, a large-scale database of data collected from electronic medical records of 2000 general practitioners in France. From 1 January 2010 to 28 February 2019, we will include eligible patients ≥75 years who will have T2D, a stable dose of HDs, glycated haemoglobin A1c (HbA1c) value <75 mmol/mol (9.0%) and no deintensification in the past year. The target trial will be sequentially emulated (ie, eligibility assessed) every month in the database. Patients will be classified at baseline of each sequential trial in the intervention arm (deintensification of HDs: decrease of ≥50% in the total dose of HDs, including complete cessation) or control arm (no deintensification of HDs). The pooled dataset for all sequential emulated trials will be analysed. The primary outcome will be time to first occurrence of hospital admission or death, within 3 months. Secondary outcomes will be hospitalisation, death, appropriateness of glycaemic control and occurrence of HbA1c >75 mmol/mol within 1 year. Participants will be followed from baseline to 12 months after randomisation, administrative censoring, or death, whichever occurs first. A pooled logistic regression will be used to estimate the treatment effect on the incidence of the outcomes.

No ethical approval is needed for using retrospectively this fully anonymised database. The results will be disseminated during conferences and through publications in scientific journals.

Treatments like glucagon-like peptide-1 receptor agonists carry low hypoglycemia risk and are recommended for elderly patients with type 2 diabetes (T2D), while some routine treatments, like insulin, increase hypoglycemia risk. The DISPEL-Advance (Dulaglutide vs Basal InSulin in Injection Naïve Patients with Type 2 Diabetes: Effectiveness in ReaL World) study compared glycemic outcomes, healthcare resource utilization, and costs in elderly patients with T2D who initiated treatment with dulaglutide versus those initiating treatment with basal insulin.

This observational, retrospective cohort study used data from the Optum Research Database. Medicare Advantage patients (≥ 65 years) with T2D were assigned to dulaglutide or basal insulin cohorts based on pharmacy claims and propensity score matched on demographic and baseline characteristics. Change in HbA1c, 12-months follow-up HbA1c, and follow-up all-cause and diabetes-related healthcare resource utilization and costs were compared.

Propensity score matching yielded well-balanced cohorts with 1891 patients each (mean age: dulaglutide, 72.09 years; basal insulin, 72.56 years). The dulaglutide cohort had significantly greater mean HbA1c reduction from baseline to follow-up than basal insulin cohort (- 0.95% vs - 0.69%; p < 0.001). The dulaglutide cohort had significantly lower mean all-cause and diabetes-related medical costs (all-cause: $8306 vs $12,176; diabetes-related: $4681 vs $7582 respectively; p < 0.001) and lower mean all-cause total costs ($18,646 vs $20,972, respectively; p = 0.007) than basal insulin cohort. The dulaglutide cohort had significantly lower all-cause and diabetes-related total costs per 1% change in HbA1c than basal insulin cohort (all-cause: $19,729 vs $30,334; diabetes-related: $12,842 vs $17,288, respectively; p < 0.001).

Elderly patients with T2D initiating dulaglutide had greater HbA1c reduction, lower mean all-cause medical and total costs, lower diabetes-related medical costs, and lower total all-cause and diabetes-related costs per 1% change in HbA1c than patients initiating basal insulin. Future studies assessing medications that do not increase hypoglycemia risk could help inform therapeutic strategies in elderly patients.
