Abstract
BackgroundPatient safety is a critical component of health care systems. Large groups of patients, as a result of medical errors, are at risk of harm. OBJECTIVE: This study evaluated the patient safety culture (PSC) between different work groups in both public and private hospitals, using machine learning approaches.MethodsThe HSOPSC questionnaire was used for evaluating safety culture, and the artificial neural network (ANN), random forest (RF) and linear regression (LR) algorithms were used for data modeling. Orange Data Mining version 3 and SPSS software were used for analysis.ResultsThe overall PSC score in public and private hospitals was 41.99 and 40.96, respectively. According to the results, the examined hospitals have a weak PSC. The safety culture level was correlated with education level, work experience, gender, income, and organizational position of the workers. The ANN showed that the issues mostly effecting PSC, in order of priority, include the feedback and communication about errors, organizational learning and continuous improvement, and management support for patient safety. Also, based on the findings LR model showed better performance for PSC prediction than RF model.ConclusionsThe healthcare experts and policymakers can improve PSC in hospitals through training and allocation of resources. Considering the importance of PSC in preventing accidents and reducing injuries, the results of the present study and the presented models can be used to predict PSC in hospitals.

Abstract
Background Medical imaging features along the entire healthcare continuum and is known for its fast-paced technological evolution which enables it to keep up with the demands of the healthcare system to provide safe, quality services. The overall efficacy and efficiency of the system depends on practitioners' clinical competence, achieved through professional education and continuous professional development. Recent studies have revealed concerns regarding newly graduated healthcare professionals' preparedness and readiness to handle actual practice. Methods We conducted qualitative face-to-face and telephonic interviews with a convenient and purposive sample of 23 participants consisting of recently graduated radiographers (n=14), radiography students (n=5) and supervising radiographers (n=4) in Australia. Verbatim transcriptions were analyzed inductively to identify themes pertaining to perspectives and experiences of the work readiness of novice radiographers. Results The findings of our study suggest that the workplace immersion and transitioning of recently graduated radiographers into their professional roles requires a process of experiential learning and honing of knowledge and skills if they are to function efficiently and independently in a team-oriented workplace. Radiographic services are spread across various levels of care and are an integral part of the organizational structure of a healthcare system. Maladaptive transitions to the workplace may be the result of low self-confidence, a lack of support, uncertainty in inter-collegial interactions, or unrealistic performance expectations. The overarching themes of communication and interaction emerged clearly as recently graduated radiographers navigated the four roles of coordinator, collaborator, mediator, and advocate. Conclusion The application of radiographic skills is embedded in a workplace culture of communication and safety. Transitioning to independent practice takes place in a complex, multifaceted environment and is accompanied by internal and external expectations. Because each workplace has a unique context, system and culture, no novice radiographic professional can ever be fully prepared through pre-service training and workplace induction.

Abstract
BACKGROUND Adverse events have become a global problem and are an important indicator of patient safety. Patient safety culture is essential in efforts to reduce adverse events in the hospital. This study aimed to investigate the status of the patient safety culture, the frequency of adverse events, and the relationship between them in Qazvin's hospitals in Iran. METHODS The present study is a descriptive-analytical study conducted in six hospitals in Qazvin, Iran, in 2020. The study population was nurses working in Qazvin hospitals. We collected data via a patient safety culture questionnaire and an adverse event checklist. Three hundred sixty nurses completed questionnaires. Multiple logistic regression was used to investigate the relationship between variables. RESULTS The highest mean of patient safety culture was related to the organizational learning dimension (3.5, SD = .074) and feedback and communication about errors (3.4, SD = 0.82). The participants gave the lowest score to dimensions of exchanges and transfer of information (2.45,=0.86) and management support for patient safety (2.62,Sd = 0.65). Management's support for patient safety, general understanding of patient safety culture, teamwork within organizational units, communication and feedback on errors, staff issues, and information exchange and transfer were significant predictors of adverse events. CONCLUSION This study confirms patient safety culture as a predictor of adverse events. Healthcare managers should provide the basis for improving the patient safety culture and reducing adverse events through methods such as encouraging the reporting of adverse events and also holding training courses for nurses.

JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2023; 42:64. [PMID: 37420259 DOI: 10.1186/s41043-023-00402-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 06/18/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND Diabetes is associated with high morbidity, mortality and quality-of-life impairment in patients. In China, the number of people suffering from diabetes ranks first in the world. Gansu Province is located in northwest China and is an economically underdeveloped region of China. By analyzing the level of health service utilization of people with diabetes in Gansu Province, the degree of equity in health service utilization and its influencing factors were studied to provide scientific data to support the promotion of health equity for people with diabetes and the introduction of relevant policies by relevant authorities. METHODS A sample of 282 people with diabetes who were 15 years old and above was chosen by multi-stage stratified sampling method. A structured questionnaire survey was conducted via face-to-face interviews. Random forest and logistic regression analysis were used to demonstrate the effects of the explanatory variables on health seeking behaviors from predisposing, enabling and need variables. The concentration index was used to indicate the equity of health service utilization across households of different economic levels. RESULTS The outpatient rate for the diabetic population surveyed was 92.91%, with 99.87% of urban patients, higher than the 90.39% of rural patients. The average number of hospital days per person was 3.18 days, with 5.03 days per person in urban areas, which was higher than the 2.51 days per person in rural areas. The study showed that the factors most likely to influence patients to seek outpatient services were frequency of taking diabetic medication, whether or not they were contracted to a household doctor, and living environment; the top three factors most likely to influence patients with diabetes to seek inpatient services were number of non-communicable chronic disease, self-assessment of health status, medical insurance. The concentration index for outpatient service utilization and inpatient service utilization were - 0.241 and 0.107, respectively, indicating that outpatient services were concentrated on patients at lower income levels and patients at higher income levels tended to favor inpatient services. CONCLUSION This study found that the low level of health care resources available to people with diabetes, whose health status is suboptimal, makes it difficult to meet their health needs. Patients' health conditions, comorbidities of people with diabetes, and the level of protection were still important factors that hindered the use of health services. It is necessary to promote the rational use of health services by diabetic patients and further improve the corresponding policies to achieve the goal of chronic disease prevention and control in "Health China 2030".

BMC Nurs 2023; 22:197. [PMID: 37296419 DOI: 10.1186/s12912-023-01358-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Accepted: 05/26/2023] [Indexed: 06/12/2023] Open
Abstract
CONTEXT The gradual impact of the Covid-19 pandemic had important effects on routines in surgical environments. In order to cope with the impact and re-establish anaesthesiology and surgery procedures, it was imperative to pursue in-depth studies with a view to ensuring safe surgical care, reducing hazards, as well as protecting the health, safety and wellbeing of the health personnel involved. The purpose of this study was to evaluate quantitative and qualitative approaches to domains of safety climate among multi-professional staffs of surgical centres during the Covid-19 pandemic and to identify intersections. METHODS This mixed-method project employed a concomitant triangulation strategy on a quantitative approach in an exploratory, descriptive, cross-sectional study, as well as a qualitative approach by way of a descriptive study. Data were collected using the validated, self-applicable Safety Attitudes Questionnaire/Operating Room (SAQ/OR) questionnaire and a semi-structured interview script. The 144 participants were the surgical, anaesthesiology, nursing and support teams working in the surgical centre during the Covid-19 pandemic. RESULTS The study found an overall safety climate score of 61.94, the highest-scoring domain being 'Communication in the surgical environment' (77.91) and the lowest, 'Perception of professional performance' (23.60). On integrating the results, a difference was found between the domains 'Communication in the surgical environment' and 'Working conditions'. However, there was intersection by the 'Perception of professional performance' domain, which permeated important categories of the qualitative analysis. CONCLUSIONS For care practice, it is hoped to encourage improved patient safety, educational interventions to strengthen the patient safety climate and promote in-job wellbeing on the job for health personnel working in surgical centres. It is suggested that further studies explore the subject in greater depth among several surgical centres with mixed methods, so as to permit future comparisons and to monitor the evolving maturity of safety climate.

Abstract
The Covid-19 pandemic has pushed the Intensive Care Units (ICUs) into significant operational disruptions. The rapid evolution of this disease, the bed capacity constraints, the wide variety of patient profiles, and the imbalances within health supply chains still represent a challenge for policymakers. This paper aims to use Artificial Intelligence (AI) and Discrete-Event Simulation (DES) to support ICU bed capacity management during Covid-19. The proposed approach was validated in a Spanish hospital chain where we initially identified the predictors of ICU admission in Covid-19 patients. Second, we applied Random Forest (RF) to predict ICU admission likelihood using patient data collected in the Emergency Department (ED). Finally, we included the RF outcomes in a DES model to assist decision-makers in evaluating new ICU bed configurations responding to the patient transfer expected from downstream services. The results evidenced that the median bed waiting time declined between 32.42 and 48.03 min after intervention.

Abstract
Patient experience is a widely used indicator for assessing the quality-of-care process during a patient's journey in hospital. However, the literature rarely discusses three components: patient stress, anxiety, and frustration. Furthermore, little is known about what drives each component during hospital visits. In order to explore this, we utilized data from a patient experience survey, including patient- and provider-related determinants, that was administered at a local hospital in Abu Dhabi, UAE. A machine-learning-based random forest (RF) algorithm, along with its embedded importance analysis function feature, was used to explore and rank the drivers of patient stress, anxiety, and frustration throughout two stages of the patient journey: registration and consultation. The attribute 'age' was identified as the primary patient-related determinant driving patient stress, anxiety, and frustration throughout the registration and consultation stages. In the registration stage, 'total time taken for registration' was the key driver of patient stress, whereas 'courtesy demonstrated by the registration staff in meeting your needs' was the key driver of anxiety and frustration. In the consultation step, 'waiting time to see the doctor/physician' was the key driver of both patient stress and frustration, whereas 'the doctor/physician was able to explain your symptoms using language that was easy to understand' was the main driver of anxiety. The RF algorithm provided valuable insights, showing the relative importance of factors affecting patient stress, anxiety, and frustration throughout the registration and consultation stages. Healthcare managers can utilize and allocate resources to improve the overall patient experience during hospital visits based on the importance of patient- and provider-related determinants.

The relationships between patient safety culture and sentinel events among hospitals in Saudi Arabia: a national descriptive study. BMC Health Serv Res 2023; 23:270. [PMID: 36934282 PMCID: PMC10024850 DOI: 10.1186/s12913-023-09205-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 02/21/2023] [Indexed: 03/19/2023] Open
Abstract
BACKGROUND Sentinel events (SEs) can result in severe and unwanted outcomes. To minimize the fear of sentinel events reporting and the occurrence of sentinel events, patient safety culture improvements within healthcare organizations is needed. To our knowledge, limited studies explored the relationships between patient safety culture and sentinel events on a local level and no research has been conducted at the national level in Saudi Arabia. OBJECTIVES This study aimed to explore the relationships between the patient safety culture and the reported-SEs on a national level during the year 2020 in Saudi hospitals. METHODS This was a descriptive study. We utilized two data sources (the reported-SEs and the patient safety culture survey) that were linked using hospitals information. To explore the relationships between patient safety culture and reported-SEs rates, we performed descriptive statistics, a test of independence, post-hoc analysis, correlation analysis, and multivariate regression and stepwise analyses. RESULTS The highest positive domain scores in patient safety culture domains in the Saudi hospitals (n = 366) were "Teamwork Within Units" (80.65%) and "Organizational learning-continuous improvement" (80.33%), and the lowest were "Staffing" (32.10%) and "Nonpunitive Response to Error" (26.19%). The highest numbers of reported-SEs in 103 hospitals were related to the contributory factors of "Communication and Information" (63.20%) and "Staff Competency and Performance" (61.04%). The correlation analysis performed on 89 Saudi hospitals showed that higher positive patient safety culture scores were significantly associated with lower rates of reported-SEs in 3 out of the 12 domains, which are "Teamwork Within Units", "Communication Openness", and "Handoffs and Transitions". Multivariate analyses showed that "Handoffs and Transitions", "Nonpunitive Response to Error", and "Teamwork Within Units" domains were significant predictors of the number of SEs. The "Staff Competency and Performance" and "Environmental Factors" were the most contributory factors of SEs in the number of significant correlations with the patient safety culture domains. CONCLUSION This study identified patient safety culture areas of improvement where hospitals in Saudi Arabia need actions. Our study confirms that a more positive patient safety culture is associated with lower occurrence of sentinel events. To minimize the fear of sentinel events reporting and to improve overall patient safety a culture change is needed by promoting a blame-free culture and improving teamwork, handoffs, and communication openness.

Abstract
Background Safety culture is an important aspect of quality in healthcare settings. There are many risks that patients can encounter in hemodialysis settings one of which is the infection risks due to the regular need to access bloodstreams using catheters and needles. Implementation of prevention guidelines, protocols and strategies that reinforce safety culture excellence are essential to mitigate risks. The objective of this study was to identify and characterize the main strategies that enhance and improve patient safety culture in hemodialysis settings. Methods Medline (via PubMed) and Scopus were searched from 2010 to 2020 in English. Terms defining safety culture, patient safety were combined with the term hemodialysis during the search. The studies were chosen based on inclusion criteria. Results A total of 17 articles reporting on six countries were identified that met inclusion criteria following the PRISMA statement. From the 17 papers, practices that were successfully applied to improve safety culture in hemodialysis settings included (i) training of nurses on the technologies used in hemodialysis treatment, (ii) proactive risk identification tools to prevent infections (iii) root cause analysis in evaluating the errors, (iv) hemodialysis checklist to be used by the dialysis nurses to reduce the adverse events, and (v) effective communication and mutual trust between the employee and leadership to support no-blame environment, and improve the safety culture. Conclusion This systematic review provided significant insights on the strategies that healthcare safety managers and policy makers can implement to enhance safety culture in hemodialysis settings.

Abstract
With the advent of machine learning (ML) and deep learning (DL) empowered applications for critical applications like healthcare, the questions about liability, trust, and interpretability of their outputs are raising. The black-box nature of various DL models is a roadblock to clinical utilization. Therefore, to gain the trust of clinicians and patients, we need to provide explanations about the decisions of models. With the promise of enhancing the trust and transparency of black-box models, researchers are in the phase of maturing the field of eXplainable ML (XML). In this paper, we provided a comprehensive review of explainable and interpretable ML techniques for various healthcare applications. Along with highlighting security, safety, and robustness challenges that hinder the trustworthiness of ML, we also discussed the ethical issues arising because of the use of ML/DL for healthcare. We also describe how explainable and trustworthy ML can resolve all these ethical problems. Finally, we elaborate on the limitations of existing approaches and highlight various open research problems that require further development.

Abstract
Individual and group beliefs, attitudes, perceptions, competences, and behavioral patterns all contribute to the safety culture of a healthcare company. The study’s goal is to assess nurses’ perceptions of elements that influence patient safety culture in order to promote long-term nursing practice. A descriptive cross-sectional study design was done among a sample of 146 nurses who were recruited from one hospital in Egypt. They completed a self-administered, printed questionnaire. The questionnaire assessed participants’ socio-demographic data and their perception regarding patient safety culture for sustainable nursing practices. The findings revealed that nursing staff had a high perception regarding patient safety culture a with mean score (159.94 ± 7.864). Also, the highest percentage (74.66%) of had no safety events reported yearly. Creating a unit-specific patient safety culture suited to the competences of the unit’s RNs in patient safety practice would be crucial to increasing and sustaining high levels of patient safety attitudes, skills, and knowledge among the unit’s RNs, influencing patient safety. When implementing interventions to promote patient safety and reporting culture in hospitals, policymakers, hospital administrators, and nurse executives should take the current findings into account. A multidimensional network intervention addressing many elements of patient safety culture and integrating different organizational levels should be implemented to enhance patient safety and a no-blame culture.

Abstract
Accurately forecasting housing prices will enable investors to attain profits, and it can provide information to stakeholders that housing prices in the community are falling, stabilizing, or rising. Previous studies on housing price forecasting mostly used hedonic pricing and weighted regression methods, which led to the lack of consideration of the nonlinear relationship model and its explanatory power. Furthermore, the attribute data of housing price forecasts are a heterogeneous study, and they are difficult to forecast accurately. Therefore, this study proposes an intelligent homogeneous model based on an enhanced weighted kernel self-organizing map (EW-KSOM) for forecasting house prices; that is, this study proposes an EW-KSOM algorithm to cluster the collected data and then applies random forest, extra tree, multilayer perception, and support vector regression to forecast the house prices of full, district, and apartment complex data. In the experimental comparison, we compare the performance of the proposed enhanced weighted kernel self-organizing map with the listing clustering methods. The results show that the best forecast algorithm is the combined EW-KSOM and random forest under the root mean square error and root-relative square error, and the proposed method can effectively improve the forecast capability of housing prices and understand the influencing factors of housing prices in full and important districts. Furthermore, we obtain that the top five key factors influencing house prices are transferred land area, house age, building transfer total area, population percentage, and the total number of floors. Lastly, the research results can provide references for investors and related organizations.

Abstract
Medical errors pose high risks to patients. Several organizational factors may impact the high rate of medical errors in complex and dynamic healthcare systems. However, limited research is available regarding probabilistic interdependencies between the organizational factors and patient safety errors. To explore this, we adopt a data-driven Bayesian Belief Network (BBN) model to represent a class of probabilistic models, using the hospital-level aggregate survey data from U.K. hospitals. Leveraging the use of probabilistic dependence models and visual features in the BBN model, the results shed new light on relationships existing among eight organizational factors and patient safety errors. With the high prediction capability, the data-driven approach results suggest that "health and well-being" and "bullying and harassment in the work environment" are the two leading factors influencing the number of reported errors and near misses affecting patient safety. This study provides significant insights to understand organizational factors' role and their relative importance in supporting decision-making and safety improvements.

Abstract
Increasingly available open medical and health datasets encourage data-driven research with a promise of improving patient care through knowledge discovery and algorithm development. Among efficient approaches to such high-dimensional problems are a number of machine learning methods, which are applied in this paper to pressure ulcer prediction in modular critical care data. An inherent property of many health-related datasets is a high number of irregularly sampled time-variant and scarcely populated features, often exceeding the number of observations. Although machine learning methods are known to work well under such circumstances, many choices regarding model and data processing exist. In particular, this paper address both theoretical and practical aspects related to the application of six classification models to pressure ulcers, while utilizing one of the largest available Medical Information Mart for Intensive Care (MIMIC-IV) databases. Random forest, with an accuracy of 96%, is the best-performing approach among the considered machine learning algorithms.

Abstract
INTRODUCTION Ensuring occupational health and safety is an enormous concern for organizations, as accidents not only harm workers but also result in financial losses. Analysis of accident data has the potential to reveal insights that may improve capabilities to mitigate future accidents. However, because accident data are often transcribed textually, analyzing these narratives proves difficult. This study contributes to a recent stream of literature utilizing machine learning to automatically label accident narratives, converting them into more easily analyzable fields. METHOD First, a large dataset of accident narratives in which workers were injured is collected from the U.S. Occupational Safety and Health Administration (OSHA). Word embeddings-based text mining is implemented; compared to past works, this methodology offers excellent performance. Second, to improve the richness of analyses, each record is assessed across five dimensions. The machine learning models provide classifications of body part(s) injured, the source of the injury, the type of event causing the injury, whether a hospitalization occurred, and whether an amputation occurred. Finally, demonstrating generalizability, the trained models are deployed to analyze two additional datasets of accident narratives in the construction industry and the mining and metals industry (transfer learning). Practical Applications: These contributions improve organizations' capacities to rapidly analyze textual accident narratives.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which caused the coronavirus disease 2019 (COVID-19) pandemic, has affected more than 400 million people worldwide. With the recent rise of new Delta and Omicron variants, the efficacy of the vaccines has become an important question. The goal of various studies has been to limit the spread of the virus by utilizing wireless sensing technologies to prevent human-to-human interactions, particularly for healthcare workers. In this paper, we discuss the current literature on invasive/contact and non-invasive/non-contact technologies (including Wi-Fi, radar, and software-defined radio) that have been effectively used to detect, diagnose, and monitor human activities and COVID-19 related symptoms, such as irregular respiration. In addition, we focused on cutting-edge machine learning algorithms (such as generative adversarial networks, random forest, multilayer perceptron, support vector machine, extremely randomized trees, and k-nearest neighbors) and their essential role in intelligent healthcare systems. Furthermore, this study highlights the limitations related to non-invasive techniques and prospective research directions.
This article describes cutting-edge technology (invasive/non-invasive) and its role in the recognition of COVID-19 symptoms. This article summarizes state-of-art machine-learning algorithms and their roles in modern healthcare systems. This article presents the challenges associated with wireless sensing techniques and potential future research directions.

BMC Health Serv Res 2021; 21:1172. [PMID: 34711229 PMCID: PMC8555195 DOI: 10.1186/s12913-021-07199-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 10/18/2021] [Indexed: 11/28/2022] Open
Abstract
Background Assessments of the culture surrounding patient safety can inform healthcare settings on how their structures and processes impact patient outcomes. This study investigated patient safety culture in Primary Health Care Centres in Kuwait, and benchmarked the findings against regional and international results. This study also examined the association between predictors and outcomes of patient safety culture in these settings. Methods This cross-sectional quantitative study used the Medical Office Survey on Patient Safety Culture. The study was targeted at staff of all the Primary Health Care Centres in Kuwait with at least one year of experience. Data were analysed using SPSS 23 at a significance level of ≤ .05. Univariate (means, standard deviations, frequencies, percentages) and bivariate (chi-squared tests, student t-tests, ANOVA F-tests, Kruskal–Wallis tests, Spearman’s correlation) analyses provided an overview of participant socio-demographics and the association between patient safety culture composites and outcomes. We undertook a multivariate regression analysis to predict the determinants of patient safety culture. Results were benchmarked against similar local (Kuwait, 2014), regional (Yemen, 2015) and international (US, 2018) studies. Results The responses of 6602 employees from 94 centres were included in the study, with an overall response rate of 78.7%. The survey revealed Teamwork (87.8% positive ratings) and Organisational Learning (78.8%) as perceived areas of strength. Communication about Error (57.7%), Overall Perceptions of Patient Safety and Quality (57.4%), Communication Openness (54.4%), Owner/Managing Partner/Leadership Support for Patient Safety (53.8%) and Work Pressure and Pace (28.4%) were identified as areas requiring improvement. Benchmarking analysis revealed that Kuwait centres are performing at benchmark levels or better on four and six composites when compared to international and regional findings, respectively. Regression modelling highlighted significant predictions regarding patient safety outcomes and composites. Conclusions This is the first major study addressing the culture of patient safety in public Primary Health Care Centres regionally. Improving patient safety culture is critical for these centres to improve the quality and safety of the healthcare services they provide. The findings of this study can guide country-level strategies to develop the systems that govern patient safety practices.

Abstract
Introduction Patient safety is an issue of global concern; however, health-care organizations have lately observed to pay more attention to the importance of establishing a culture of safety. The study aimed to assess the level of patient safety culture and associated factors among health-care providers at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia, 2020. Methods A cross-sectional study design supported by the qualitative approach was conducted from March 15 to May 15/2020. A stratified simple sampling technique was used to select 575 study participants. The standardized tool, which measures 12 safety culture dimensions, was used for data collection. Bivariate and multivariable linear regression analyses performed using SPSS version 23. The significance level was obtained at 95% CI and p-value <0.05. For the qualitative part, a semi-structured interview guide with probing was used. Data were analyzed thematically using open code software version 4.02. Results The overall level of positive patient safety culture was 45.3% (95% CI: 44.7, 45.9) with a response rate of 92.2%. Factor analysis indicated that female, masters, participation in patient safety program, adverse event report, hospital management encourage reporting event and resource were positively associated with the patient safety culture. Whereas divorced/widowed, midwives, anesthetist, medicine, pediatrics, emergency, outpatient, pharmacy, direct contact with patients, and hospital management blame when medical errors happened were negatively associated. The in-depth interview revealed that teamwork, health-care professionals’ attitude toward patient safety and patient involvement as important factors that influence patient safety culture. Conclusions and Recommendations The overall level of positive patient safety culture was low. All variables except age, training, working hour, and working experience were factors significantly associated with the patient safety culture. Health-care policy-makers and managers should consider patient safety culture a top priority, and also create a blame-free environment that promotes event reporting.

Abstract
In healthcare, most accidents occur as a result of inadequate interactions between system components rather than component failures. In such cases traditional risk analysis methods are of limited use for analysing system safety, so methods such as Systems Theoretic Process Analysis (STPA) and the Functional Resonance Analysis Method (FRAM) have been developed. This study uses STPA to assess risks in the sepsis treatment process, discusses the potential value STPA adds and compares the results of STPA with the results of another study that used FRAM. The findings indicate that STPA and FRAM have different strengths which reflect the different scientific approaches behind these two methods. FRAM facilitates an in-depth understanding of a system, while STPA allows for more comprehensive risk analysis by identifying more risks, scenarios and safety recommendations. Nevertheless, it is reasonable to say that not only does STPA provide more comprehensive risk analysis; its terminology and philosophy are also closer to the current safety management applications employed in complex systems.

Abstract
With the rapid development of “We media” technology, netizens can freely express their opinions regarding enterprise products on a network platform. Consequently, online public opinion about enterprises has become a prominent issue. Negative comments posted by some netizens may trigger negative public opinion, which can have a significant impact on an enterprise’s image. From the perspective of helping enterprises deal with negative public opinion, this paper combines user portrait technology and a random forest algorithm to help enterprises identify high-risk users who have posted negative comments and thus may trigger negative public opinion. In this way, enterprises can monitor the public opinion of high-risk users to prevent negative public opinion events. Firstly, we crawled the information of users participating in discussions of product experience, and we constructed a portrait of enterprise public opinion users. Then, the characteristics of the portraits were quantified into indicators such as the user’s activity, the user’s influence, and the user’s emotional tendency, and the indicators were sorted. According to the order of the indicators, the users were divided into high-risk, moderate-risk, and low-risk categories. Next, a supervised high-risk user identification model for this classification was established, based on a random forest algorithm. In turn, the trained random forest identifier can be used to predict whether the authors of newly published public opinion information are high-risk users. Finally, a back propagation neural network algorithm was used to identify users and compared with the results of model recognition in this paper. The results showed that the average recognition accuracy of the back propagation neural network is only 72.33%, while the average recognition accuracy of the model constructed in this paper is as high as 98.49%, which verifies the feasibility and accuracy of the proposed random forest recognition method.

Abstract
Background Patient satisfaction is a multi-dimensional concept that provides insights into various quality aspects in healthcare. Although earlier studies identified a range of patient and provider-related determinants, their relative importance to patient satisfaction remains unclear. Methods We used a tree-based machine-learning algorithm, random forests, to estimate relationships between patient and provider-related determinants and satisfaction level in two of the main patient journey stages, registration and consultation, through survey data from 411 patients at a hospital in Abu Dhabi, UAE. Radar charts were also generated to determine which type of questions—demographics, time, behaviour, and procedure—influence patient satisfaction. Results Our results showed that the ‘age’ attribute, a patient-related determinant, is the leading driver of patient satisfaction in both stages. ‘Total time taken for registration’ and ‘attentiveness and knowledge of the doctor/physician while listening to your queries’ are the leading provider-related determinants in each model developed for registration and consultation stages, respectively. The radar charts revealed that ‘demographics’ are the most influential type in the registration stage, whereas ‘behaviour’ is the most influential in the consultation stage. Conclusions Generating valuable results, the random forest model provides significant insights on the relative importance of different determinants to overall patient satisfaction. Healthcare practitioners, managers and researchers can benefit from applying the model for prediction and feature importance analysis in their particular healthcare settings and areas of their concern.

Identification of the Framingham Risk Score by an Entropy-Based Rule Model for Cardiovascular Disease. ENTROPY 2020; 22:e22121406.

Abstract
Since 2001, cardiovascular disease (CVD) has had the second-highest mortality rate, about 15,700 people per year, in Taiwan. It has thus imposed a substantial burden on medical resources. This study was triggered by the following three factors. First, the CVD problem reflects an urgent issue. A high priority has been placed on long-term therapy and prevention to reduce the wastage of medical resources, particularly in developed countries. Second, from the perspective of preventive medicine, popular data-mining methods have been well learned and studied, with excellent performance in medical fields. Thus, identification of the risk factors of CVD using these popular techniques is a prime concern. Third, the Framingham risk score is a core indicator that can be used to establish an effective prediction model to accurately diagnose CVD. Thus, this study proposes an integrated predictive model to organize five notable classifiers: the rough set (RS), decision tree (DT), random forest (RF), multilayer perceptron (MLP), and support vector machine (SVM), with a novel use of the Framingham risk score for attribute selection (i.e., F-attributes first identified in this study) to determine the key features for identifying CVD. Verification experiments were conducted with three evaluation criteria-accuracy, sensitivity, and specificity-based on 1190 instances of a CVD dataset available from a Taiwan teaching hospital and 2019 examples from a public Framingham dataset. Given the empirical results, the SVM showed the best performance in terms of accuracy (99.67%), sensitivity (99.93%), and specificity (99.71%) in all F-attributes in the CVD dataset compared to the other listed classifiers. The RS showed the highest performance in terms of accuracy (85.11%), sensitivity (86.06%), and specificity (85.19%) in most of the F-attributes in the Framingham dataset. The above study results support novel evidence that no classifier or model is suitable for all practical datasets of medical applications. Thus, identifying an appropriate classifier to address specific medical data is important. Significantly, this study is novel in its calculation and identification of the use of key Framingham risk attributes integrated with the DT technique to produce entropy-based decision rules of knowledge sets, which has not been undertaken in previous research. This study conclusively yielded meaningful entropy-based knowledgeable rules in tree structures and contributed to the differentiation of classifiers from the two datasets with three useful research findings and three helpful management implications for subsequent medical research. In particular, these rules provide reasonable solutions to simplify processes of preventive medicine by standardizing the formats and codes used in medical data to address CVD problems. The specificity of these rules is thus significant compared to those of past research.
