Titanium metal clips have classically been used to occlude the cystic artery and duct during laparoscopic cholecystectomy (LC). Non-absorbable, polymer clips are an alternative with a locking feature. There is limited research evaluating the adoption, safety, and cost of these clips during cholecystectomy.

A retrospective review was conducted on patients undergoing elective LC from 2017 to 2019. The cohort was divided based on the use of metal or polymer clips. The primary outcome was 30-day emergency department (ED) visit rate. Secondary outcomes included readmission and complications. Surgeon utilization and cost comparison were assessed. Chi square, Wilcoxon rank-sum, and multivariable logistic regression was performed.

1244 patients underwent LC by 38 surgeons, of which 934 (75.1%) utilized metal clips. Thirty-day ED presentation was 8.5%, with a higher rate for the polymer clip group (12.4% vs 7.2%, p = 0.005); 79% of presentations were related to the operation. On adjusted analysis, ED visits were associated with hospital facility and insurance payor. Thirty-day readmission rate was comparable for polymer and metal clips (4.9% vs 3.2%, p = 0.18, respectively). Most surgeons used metal clips (58%) and there was no impact based on fellowship training. Those who preferentially utilized polymer clips had more recently graduated from medical school (p = 0.02) and were more likely to perform intraoperative cholangiograms (p < 0.001). The device cost difference favored polymer clips by $75 per case.

Polymer clips are a safe alternative to metal clips, with a similarly low complication profile. Despite an increase in 30-day ED visit rate in the polymer group, adjusted analysis demonstrated an association with hospital facility and insurance type, and not clip type. Given LC is one of the most commonly performed operations worldwide, the benefit of locking polymer clips should be incorporated into intraoperative decision making.

To quantify how surgical complications impact hospital revenue when their effect on the volume of admissions is considered.

Retrospective analysis of comprehensive administrative data.

Three university hospitals in France.

54 637 inpatient stays between 2017 and 2023 in 4 surgical departments (abdominal, orthopedics, thoracic, and urology).

Stays were categorized by their diagnosis-related group and occurrence of one or more complications, according to International Classification of Diseases, 10th revision diagnosis codes. First, data were aggregated monthly to determine the impact of variation in the monthly mean length of stay (LOS) on the monthly volume of admissions, using an instrumental variable strategy. Second, LOS and revenue per patient were compared for patients with and without complications. Finally, an estimation of the impact of complications on total revenue was performed.

A total of 54 637 stays were analyzed, with 9735 (17.8%) experiencing at least one complication. The mean LOS was 8.7 days and the mean revenue per patient was €7602. The instrumental variable analysis, designed to account for unobserved confounders, showed that a decrease of 10% in the monthly mean LOS increased the monthly volume of admissions by 9% (95% CI (5.1% to 13.0%), p<0.01). Complications increased the LOS by 10.9 days (95% CI: (8.95 to 13.1), p<0.01) and revenue per patient by €7912 (95% CI: (6420 to 9087), p<0.01), but decreased daily revenue per patient by €211 (95% CI: (-384 to -83.0), p<0.01). Over the study period, the estimated potential loss induced by complications ranged from 6.6% (95% CI (6.3% to 7.0%), p<0.01) to 9.1% (95% CI (8.8% to 9.4%), p<0.01) of actual revenue. Departments with higher complication rates incurred larger potential losses.

Surgical complications reduce total revenue by crowding out short stays that generate more daily revenue. This challenges the consensus that complications are a boon for hospital revenue, instead implying that they shrink hospital net margins (ie, revenue minus costs).

The cost-to-charge ratio reflects the markup of hospital services. A lower cost-to-charge ratio indicates lower costs and/or greater charges. This study examines factors associated with cost-to-charge ratio trends to determine whether decreasing cost-to-charge ratio is associated with worse surgical outcomes.

The Florida Agency for Healthcare Administration Inpatient database (2018-2020) was queried for common surgical procedures and linked to the Distressed Communities Index, RAND Corporation Hospital data, Center for Medicare Services Cost Reports, and American Hospital Association data. Only hospitals with monotonically increasing or decreasing cost-to-charge ratio were included in the study. Univariable analysis compared these hospitals. Using patient-level data, interpretable machine learning predicted cost-to-charge ratio trend while identifying influential factors.

The cohort had 67 hospitals (27 increasing cost-to-charge ratio and 40 decreasing cost-to-charge ratio) with 35,661 surgeries. Decreasing cost-to-charge ratio hospitals were more often proprietarily owned (78% vs 33%, P = .01) and had greater mean total charges ($134,349 ± $114,510 vs $77,185 ± $82,027, P < .01) with marginally greater mean estimated costs ($14,863 ± $12,343 vs $14,458 ± $15,440, P < .01). Patients from decreasing cost-to-charge ratio hospitals had greater rates of most comorbidities (P < .05) but no difference in mortality or overall complications. Machine-learning models revealed charges rather than clinical factors as most influential in cost-to-charge ratio trend prediction.

Decreasing cost-to-charge ratio hospitals charge vastly more despite minimally greater estimated costs and no difference in outcomes. Although differences in case-mix existed, charges were the predominant differentiators. Patient clinical factors had far less of an impact.

Transparency around surgeon level data may align healthcare delivery with quality care for patients. Biliary surgery includes numerous procedures performed by both general surgeons and subspecialists alike. Cholecystectomy is a common surgical procedure and an optimal cohort to measure quality outcomes within a healthcare system.

Data were collected for 5084 biliary operations performed by 68 surgeons in 11 surgical divisions in a health system including a tertiary academic hospital, two regional community hospitals, and two ambulatory surgery centers. A privacy protected dashboard was developed to compare surgeon performance and cost between July 2018 and June 2022. A sample cohort of patients ≥ 18 years who underwent cholecystectomy were compared by operative time, cost, and 30-day outcomes.

Over 4 years, 4568 cholecystectomy procedures were performed by 57 surgeons. Operations were done by 57 surgeons in four divisions and included 3846 (84.2%) laparoscopic cholecystectomies, 601 (13.2%) laparoscopic cholecystectomies with cholangiogram, and 121 (2.6%) open cholecystectomies. Patients were admitted from the emergency room in 2179 (47.7%) cases while 2389 (52.3%) cases were performed in the ambulatory setting. Individual surgeons were compared to peers for volume, intraoperative data, cost, and outcomes. Cost was lowest at ambulatory surgery centers, yet only 4.2% of elective procedures were performed at these facilities. Prepackaged kits with indocyanine green were more expensive than cholangiograms that used iodinated contrast. The rate of emergency department visits was lowest when cases were performed at ambulatory surgery centers.

Data generated from clinical dashboards can inform surgeons as to how they compare to peers regarding quality metrics such as cost, time, and complications. In turn, this may guide strategies to standardize care, optimize efficiency, provide cost savings, and improve outcomes for cholecystectomy procedures. Future application of clinical dashboards can assist surgeons and administrators to define value-based care.

In 2014, 56 Illinois hospitals came together to form a unique learning collaborative, the Illinois Surgical Quality Improvement Collaborative (ISQIC). Our objectives are to provide an overview of the first three years of ISQIC focused on (1) how the collaborative was formed and funded, (2) the 21 strategies implemented to support quality improvement (QI), (3) collaborative sustainment, and (4) how the collaborative acts as a platform for innovative QI research.

ISQIC includes 21 components to facilitate QI that target the hospital, the surgical QI team, and the peri-operative microsystem. The components were developed from available evidence, a detailed needs assessment of the hospitals, reviewing experiences from prior surgical and non-surgical QI Collaboratives, and interviews with QI experts. The components comprise 5 domains: guided implementation (e.g., mentors, coaches, statewide QI projects), education (e.g., process improvement (PI) curriculum), hospital- and surgeon-level comparative performance reports (e.g., process, outcomes, costs), networking (e.g., forums to share QI experiences and best practices), and funding (e.g., for the overall program, pilot grants, and bonus payments for improvement).

Through implementation of the 21 novel ISQIC components, hospitals were equipped to use their data to successfully implement QI initiatives and improve care. Formal (QI/PI) training, mentoring, and coaching were undertaken by the hospitals as they worked to implement solutions. Hospitals received funding for the program and were able to work together on statewide quality initiatives. Lessons learned at one hospital were shared with all participating hospitals through conferences, webinars, and toolkits to facilitate learning from each other with a common goal of making care better and safer for the surgical patient in Illinois. Over the first three years, surgical outcomes improved in Illinois.

The first three years of ISQIC improved care for surgical patients across Illinois and allowed hospitals to see the value of participating in a surgical QI learning collaborative without having to make the initial financial investment themselves. Given the strong support and buy-in from the hospitals, ISQIC has continued beyond the initial three years and continues to support QI across Illinois hospitals.

We examine whether caps on noneconomic damages in medical malpractice cases affect in-hospital patient safety. We use Patient Safety Indicators - measures of adverse events - as proxies for safety. In difference-in-differences ("DiD") analyses of five states that adopt caps during 2003-2005, we find that multiple measures of non-fatal patient safety events worsen after cap adoption relative to control states. DiD inference can be unreliable with a small number of treated units. We therefore develop a randomization inference-based test for inference with few treated units but multiple correlated outcomes and confirm the robustness of our results with this nonparametric approach. We also provide evidence that the decline in patient safety is unlikely to be driven by patient selection.

Since the introduction of the Bundled Payments for Care Improvement initiative, progress has been made in piloting bundled payment models to improve care coordination and curtail health care expenditures. In light of improvements in patient outcomes and the concomitant reduction in health care spending for certain high-volume and high-cost procedures, such as total joint arthroplasty and breast reconstruction, the authors discuss theoretical considerations for bundling payments for the care of patients with orofacial clefts. The reasons for and against adopting such a payment model to consolidate cleft care, as well as the challenges to implementation, are discussed. The authors purport that bundled payments can centralize components of cleft care and offer financial incentives to reduce costs and improve the value of care provided, but that risk adjustment based on the longitudinal nature of care, disease severity, etiologic heterogeneity, variations in outcomes reporting, and varying definitions of the episode of care remain significant barriers to implementation.

Multidisciplinary care has been previously shown to improve outcomes for patients and providers alike, fostering interprofessional collaboration and communication. Many studies have demonstrated the beneficial health care outcomes of interdisciplinary care. However, there has been minimal focus on the cost-effectiveness of such care, particularly in the realm of plastic surgery. This is the first systematic review to examine cost savings attributable to plastic surgery involvement in multidisciplinary care.

A comprehensive literature review of articles published on cost outcomes associated with multidisciplinary teams including a plastic surgeon was performed. Included articles reported on cost outcomes directly or indirectly attributable to a collaborative intervention. Explicitly reported cost savings were totaled on a per-patient basis. Each article was also reviewed to determine whether the authors ultimately recommended the team-based intervention described.

A total of 604 articles were identified in the initial query, of which 8 met the inclusion criteria. Three studies reported explicit cost savings from multidisciplinary care, with cost savings ranging from $707 to $26,098 per patient, and 5 studies reported changes in secondary factors such as complication rates and length of stay. All studies ultimately recommended multidisciplinary care, regardless of whether cost savings were achieved.

This systematic review of the cost-effectiveness of multidisciplinary plastic surgery care examined both primary cost savings and associated quality outcomes, such as length of stay, complication rate, and resource consumption. Our findings indicate that the inclusion of plastic surgery in team-based care provides both direct and indirect cost savings to all involved parties.

The COVID-19 pandemic has recently put a stop to elective surgical procedures across Canada, inherently compounding already lengthy waitlists that exist within most disciplines of surgery. These long waits for elective procedures within Canadian provinces have not been caused by the COVID-19 pandemic; it is an acute-on-chronic issue that has been exacerbated by the ongoing COVID-19 pandemic. As hospitals begin to reschedule elective surgeries, patients are likely to be prioritized by clinical urgency using both established and newly created surgical triage severity scales. The objective of this commentary is to discuss issues related to the rebooking of elderly surgical patients during the COVID-19 pandemic within the context of northern medicine. Northern and rural hospitals may already face a multitude of barriers related to the rebooking of surgical patients due to a paucity of available surgical resources, as well as difficulties related to accessing care at the local level. While current surgical rebooking tools have been developed in response to the COVID-19 pandemic, they fail to explore certain risks related to the older adult population which may lead to increased mortality and morbidity. Review of the literature indicates that redistribution of surgical resources for older adults in the COVID-19 era will require consideration of clinical medical ethics vs. population health ethics regarding who should be prioritized in re-bookings for elective surgical procedures. This should be done in conjunction with encompassing surgical triage severity scales specifically made for older adults in the time of COVID-19.

Multidisciplinary care has been shown to improve outcomes for patients, and interprofessional collaboration has been demonstrated to be beneficial for providers. In the field of surgery, although a large number of multidisciplinary care teams have been described, no study to date has examined whether or not these team-based interventions are generally cost-effective. This is the first systematic review to examine cost savings attributable to multidisciplinary care across all surgical fields.

A comprehensive literature review of articles published on cost outcomes associated with multidisciplinary surgical teams was performed. Selected articles reported on cost outcomes directly attributable to a collaborative intervention. Cost savings were totaled on a per-patient basis. Each article was also reviewed to determine whether the authors ultimately recommended the team-based intervention described.

A total of 1421 articles were identified in the initial query, of which 43 met inclusion criteria. Thirty-nine studies (91%) reported multidisciplinary care to be cost effective, with an average cost savings among all studies of $5815 per patient. No significant differences in the amount of savings achieved were found between different intervention subtypes. All studies ultimately recommended (40) or gave mixed reviews (3) of multidisciplinary care, regardless of whether cost savings were achieved.

Multidisciplinary surgical care is beneficial not only in terms of patient and provider outcomes, but also in reference to its cost-effectiveness. Well-designed multidisciplinary teams tend to optimize perioperative care for all involved parties. Efforts to improve surgical care should employ multidisciplinary teams to promote both quality and cost-effective care.

Postoperative complications (PC) are a basic health outcome, but no surgery service in the world records and/or audits the PC associated with all the surgical procedures it performs. Most studies that have assessed the cost of PC suffer from poor quality and a lack of transparency and consistency. The payment system in place often rewards the volume of services provided rather than the quality of patients' clinical outcomes. Without a thorough registration of PC, the economic costs involved cannot be determined. An accurate, reliable appraisal would help identify areas for investment in order to reduce the incidence of PC, improve surgical results, and bring down the economic costs. This article describes how to quantify and classify PC using the Clavien-Dindo classification and the comprehensive complication index, discusses the perspectives from which economic evaluations are performed and the minimum postoperative follow-up established, and makes various recommendations. The availability of accurate and impartially audited data on PC will help reduce their incidence and bring down costs. Patients, the health authorities, and society as a whole are sure to benefit.

The aim of this study was to systematically synthesize the large volume of literature reporting on the association between operative duration and complications across various surgical specialties and procedure types.

An electronic search of PubMed, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews from January 2005 to January 2015 was conducted. Sixty-six observational studies met the inclusion criteria.

Pooled analyses showed that the likelihood of complications increased significantly with prolonged operative duration, approximately doubling with operative time thresholds exceeding 2 or more hours. Meta-analyses also demonstrated a 14% increase in the likelihood of complications for every 30 min of additional operating time.

Prolonged operative time is associated with an increase in the risk of complications. Given the adverse consequences of complications, decreased operative times should be a universal goal for surgeons, hospitals, and policy-makers. Future study is recommended on the evaluation of interventions targeted to reducing operating time.

The modified Clavien-Dindo (MCD) system is a reliable tool for classifying adverse events (AEs) in hip preservation surgery and has since been utilized in studies involving lower limb surgery for ambulant and nonambulant children with cerebral palsy (CP). However, the profile of AEs recorded in children with CP compared with typically developing children is different, and the reliability of the MCD in CP is unknown. This study aimed to evaluate the interrater and intrarater reliability of the MCD system for classifying AEs following lower limb surgery in children with CP.

Eighteen raters were invited to participate, including clinicians from surgical, nursing, and physical therapy professions, and individuals with CP. Following a MCD familiarization session, participants rated 40 clinical scenarios on 2 occasions, 2 weeks apart. Fleiss' κ statistics were used to calculate interrater and intrarater reliability.

The overall Fleiss' κ value for interrater reliability in the first rating was 0.70 (95% confidence interval, 0.61-0.80), and increased to 0.75 (95% confidence interval, 0.66-0.84) in the second rating. The average Fleiss' κ value for intrarater reliability was 0.78 (range, 0.48 to 1.00). Grading of more severe AEs (MCD III to V) achieved near perfect agreement (κ, 0.87 to 1.00). There was a lower level of agreement for minor AEs (MCD I-II) (κ, 0.53 to 0.55). A κ score of 0 to 0.2 was deemed as poor, 0.21 to 0.4 as fair, 0.41 to 0.6 as good, 0.61 to 0.8 as very good, and 0.81 to 1.0 as almost perfect agreement.

The MCD System demonstrates a very good interrater and intrarater reliability following lower limb surgery in children with CP. The MCD can be used by clinicians from different health care professions with a high level of reliability. The MCD may improve standardization of AE recording with a view to accurate audits and improved clarity in outcome studies for CP.

Level II-diagnostic.

A major restructuring of perioperative care delivery is required to reduce cost while improving patient outcomes. In a test implementation of this notion, we developed and implemented a perioperative consult service (PCS) for colorectal surgery patients.

A 6-month planning process was undertaken to engage key stakeholders from surgery, nursing, and anesthesia in a healthcare redesign project that resulted in the creation of a PCS to implement a coordinated clinical pathway. After Institutional Review Board (IRB) approval, data were collected for all elective colorectal procedures for three phases: phase 0 (pre-implementation; 1/2014-6/2014), phase 1 (7/2014-10/2014), and phase 2 (11/2014-10/2015). Length of stay (primary endpoint; LOS), total hospital cost, use of clinical pathway components, markers of functional recovery, and readmission and reoperation rates were analyzed. Outcomes and patient characteristics among phases were compared by two-tailed t tests and Wilcoxon rank-sum tests. Categorical variables were analyzed by chi-square and Fisher's exact tests.

We studied 544 patients (phase 0 = 179; phase 1 = 124; phase 2 = 241), with 365 consecutive patients being cared for in the redesigned care structure. Median LOS was reduced and sustained after implementation (phase 0, 4.24 days; phase 1, 3.32 days; phase 2, 3.32 days, P < 0.01 phase 0 v. phases 1 and 2), and mean LOS was reduced in phase 2 (phase 0, 5.26 days; phase 1, 4.93 days; phase 2, 4.36 days, P < 0.01 phase 0 v. phase 2). Total hospital cost was reduced by 17 % (P = 0.05, median). Application of clinical pathway components was higher in phases 1 and 2 compared to phase 0 (P < 0.01 for all components except anti-emetics); measures of functional recovery improved with successive phases. Reoperation and 30-day readmission rates were no different in phase 1 or phase 2 compared to phase 0 (P > 0.15).

Restructuring of perioperative care delivery through the launch of a PCS-reduced LOS and total cost in a significant and sustainable fashion for colorectal surgery patients. Based on the success of this care redesign project, hospital administration is funding expansion to additional services.

Little is known about the postoperative complications experienced by patients with severe cerebral palsy (CP) (GMFCS IV-V) compared with otherwise healthy patients with hip pathology requiring surgery. The purpose of this study was to determine whether differences exist between these 2 groups with respect to the incidence, type, and severity of complications. In addition, we evaluated the risk factors for complications and the number and cost of additional visits, hospital admissions, and repeat surgeries due to complications.

Retrospective matched cohort study of 55 patients aged 3 to 25 years with severe CP and 55 non-CP patients with hip dysplasia who underwent hip osteotomies (2000 to 2012). Postoperative complications were evaluated using the adapted Clavien-Dindo classification system. Binary and ordinal logistic regressions were used to identify risk factors for complications. The number and cost of unplanned visits, admissions, and surgeries were calculated.

CP patients experienced almost twice as many complications as the non-CP patients (P=0.004). All types of complications occurred in both groups except orthopaedic complications (P<0.001) were more frequent in the non-CP group. CP patients were 82% more likely to develop a complication compared with non-CP patients (relative risk=1.82; 95% confidence interval=1.21 to 2.76). The severity of complications was comparable with no significant differences in the relative distribution between the groups. There was a significant difference between groups for the number of unplanned clinic and emergency department visits (P≤0.001). The average cost for treating a complication was $1857.00 for CP and $1800.00 for non-CP (P=0.72).

Although patients with severe CP requiring hip surgery have a 65% chance of experiencing at least 1 postoperative complication compared with 36% of non-CP patients, most of the complications were medical in the CP patients (n=46, 83%) as opposed to the non-CP patient who experienced predominantly orthopaedic complications (59%). When these complications occur the associated costs are greater for CP patients as a whole, but are relatively similar per patient.

Level III—Prognostic, case-control study.

To determine the relationship between complications after 3 common general surgery procedures and per-episode hospital finances.

With impending changes in health care reimbursement, maximizing the value of care delivered is paramount. Data on the relative clinical and financial impact of postoperative complications are necessary for directing surgical quality improvement efforts.

We reviewed the medical records of patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program who underwent pancreaticoduodenectomy, hepatectomy, and colectomy at a single academic institution between September 2009 and August 2012. Clinical outcomes data were subsequently linked with hospital billing data to determine hospital finances associated with each episode. We describe the association between postoperative complications, hospital length of stay, and different financial metrics. Multivariable linear regression modeling tested linear association between postoperative outcomes and cost data.

There was a positive association between the number of surgical complications, payments, length of stay, total charges, total costs, and contribution margin for the three procedures. Multivariable models indicated that complications were independently associated with total cost among the selected procedures. Payments increased with complications, offsetting increased costs.

In the current fee-for-service environment, the financial incentives are misaligned with quality improvement efforts. As we move to a value-driven method of reimbursement, administrators and health care providers alike will need to focus on improving the quality of patient care while remaining conscious of the cost of care delivered. Reducing complications effectively improves value.

To examine the financial impact of quality improvement using Medicare payment data.

Demonstrating a business case for quality improvement--that is, that fewer complications translates into lower costs--is essential to justify investment in quality improvement. Prior research is limited to cross-sectional studies showing that patients with complications have higher costs. We designed a study to better evaluate the relationship between payments and complications by using quality improvement itself as a measured outcome.

We used national Medicare data for patients undergoing general (n = 1,485,667) and vascular (n = 531,951) procedures. We calculated hospitals' rates of serious complications in 2 time periods: 2003-2004 and 2009-2010. We sorted hospitals into quintiles by the change in complication rates across these time periods. Costs were assessed using price-standardized Medicare payments, and regression analyses used to determine the average change in payments over time.

There was significant change in serious complication rates across the 2 time periods. The top 20% of hospitals demonstrated a 38% decrease (14.3% vs 11.6%, P < 0.001) in complications; in contrast the bottom 20% demonstrated a 25% increase (11.1% vs 16.5%, P < 0.001). There was a strong relationship between quality improvement and payments. The top hospitals reduced their payments by $1544 per patient (95% confidence interval: $1334-1755), whereas the bottom of hospitals had no significant change (average $67 increase, 95% confidence interval: -$123 to $258).

Hospitals that reduced their complications over time had significant reductions in Medicare payments. This demonstrates that payers are clearly incentivized to invest in quality improvement.

Accreditation Council for Graduate Medical Education (ACGME) core competencies of systems-based practice and practice-based learning and improvement are difficult to assess, as they are often not directly measurable or observable. Reviewing day-of-surgery cancellations could provide resident learning opportunities in these areas.

An automated system to facilitate anesthesiology resident review of cancelled cases was implemented on the Preoperative Evaluation Clinic (PEC) rotation at the authors' institution. This study aims to evaluate its impact on resident education.

Residents on the PEC rotation during the 6 months preceding (n = 22) and following (n = 13) implementation in 2014 were surveyed about their experience performing cancelled case reviews in order to ascertain the effect of the intervention on their training.

Significant changes were reported in the number of cases reviewed by each resident (p < 0.0001), perceived importance of review (p = 0.03), and ease of review (p = 0.03) after system implementation. There was also an increase in the proportion of cancelled cases reviewed from 17.3% (34 of 196) to 95.6% (194 of 203) (p < 0.0001). Non-significant trends were seen in perceived rotation effect on ACGME competencies, including systems-based practice. Several specific improvements to our clinical practice, including the creation of standardized guidelines, arose from these case reviews.

Implementation of automated systems can improve compliance with educational goals by clarifying priorities and simplifying workflow. This system increased the number of cases reviewed by residents and the perceived importance of this review as a part of their educational experience.

The quality of the relationship between the sterile processing department (SPD) and the operating room (OR) is an important determinant of OR safety and performance. In this article, the concept of "friction" refers to the SPD behaviors and attributes that can negatively affect OR performance. Panels of SPD professionals initially were asked to identify and operationally define different ways in which behaviors of a hospital's SPD could compromise OR performance. A national convenience sample of OR nurses (N=291) rated 14 frictions in terms of their agreement or disagreement that each had a negative effect on OR performance in their hospital. Overall, more than 50% of the entire sample agreed that 2 frictions, "SPD does not communicate effectively with the OR" (55%) and "SPD inventories are insufficient for surgical volume" (52%), had negative effect on OR performance. However, a latent class analysis revealed 3 distinct classes of nurses who varied with respect to their level of agreement that SPD-OR frictions negatively affected OR performance. The observed heterogeneity in how different groups of nurses viewed different frictions suggests that effective efforts aimed at reducing performance-limiting frictions should be customized so that resources can be used where they are most needed.

On the basis of a systematic review, we aimed to establish the cost and drivers of cost and/or resource use of intra- and perioperative complications occurring as a result of selected major surgical procedures, as well as to understand the relationship between costs and severity of complication and, consequently, the economic burden they represent. We also assessed the clinical and economic methodologies used to derive costs and resource use across the studies with a view to providing guidance on reporting standards for these studies.

We searched EMBASE, MEDLINE and Econlit (from 2002 to 2012) for study publications including resource use/cost data relating to surgical complications.

We identified 38 relevant studies on pancreatic (n = 14), urologic (n = 4), gynaecological (n = 6), thoracic (n = 13) and hepatic surgery (n = 1). All studies showed that complications lead to higher resource use and hospital costs compared with surgical procedures without complications. Costs depend on type of complication and complication severity, and are driven primarily by prolonged hospitalisation. There was considerable heterogeneity between studies with regard to patient populations, outcomes and procedures, as well as a lack of consistency and transparency of reporting of costs/resource use. Complication severity grading systems were used infrequently.

The overall conclusions of included studies are consistent: complications represent an important economic burden for health care providers. We conclude that more accurate and consistent data collection is required to serve as input for good-quality economic analyses, which in turn can inform hospital decisions on cost-efficient allocation of their limited resources.
