Promising algorithms to perilous applications: a systematic review of risk stratification tools for predicting healthcare utilisation.

OBJECTIVES: Risk stratification tools that predict healthcare utilisation are extensively integrated into primary care systems worldwide, forming a key component of anticipatory care pathways, where high-risk individuals are targeted by preventative interventions. Existing work broadly focuses on comparing model performance in retrospective cohorts with little attention paid to efficacy in reducing morbidity when deployed in different global contexts. We review the evidence supporting the use of such tools in real-world settings, from retrospective dataset performance to pathway evaluation. METHODS: A systematic search was undertaken to identify studies reporting the development, validation and deployment of models that predict healthcare utilisation in unselected primary care cohorts, comparable to their current real-world application. RESULTS: Among 3897 articles screened, 51 studies were identified evaluating 28 risk prediction models. Half underwent external validation yet only two were validated internationally. No association between validation context and model discrimination was observed. The majority of real-world evaluation studies reported no change, or indeed significant increases, in healthcare utilisation within targeted groups, with only one-third of reports demonstrating some benefit. DISCUSSION: While model discrimination appears satisfactorily robust to application context there is little evidence to suggest that accurate identification of high-risk individuals can be reliably translated to improvements in service delivery or morbidity. CONCLUSIONS: The evidence does not support further integration of care pathways with costly population-level interventions based on risk prediction in unselected primary care cohorts. There is an urgent need to independently appraise the safety, efficacy and cost-effectiveness of risk prediction systems that are already widely deployed within primary care.

Mapping Strategies for Strengthening Safety Culture: A Scoping Review.

BACKGROUND: Twenty years after the "To Err Is Human" report, one in ten patients still suffer harm in hospitals in high-income countries, highlighting the need to strengthen the culture of safety in healthcare. This scoping review aims to map patient safety culture strengthening strategies described in the literature. METHOD: This scoping review follows the JBI methodology. It adhered to all scoping review checklist items (PRISMA-ScR) with searches in the Lilacs, MedLine, IBECS, and PubMed databases and on the official websites of Brazilian and North American patient safety organizations. The research took place during the year 2023. RESULTS: In total, 58 studies comprising 52 articles and 6 documents from health organizations were included. Various strategies were identified and grouped into seven categories based on similarity, highlighting the need for a comprehensive organizational approach to improve patient care. The most described strategies were communication (69%), followed by teamwork (58.6%) and active leadership (56.9%). CONCLUSION: The identified strategies can promote the development of a culture in which an organization can achieve patient safety, involving practices and attitudes that reduce risks and errors in healthcare. However, the identification of strategies is limited because it is restricted to certain databases and websites of international organizations and does not cover a broader spectrum of sources. Furthermore, the effectiveness of these strategies in improving patient safety culture has not yet been evaluated.

Structural equation modeling approach for the analysis of ergonomics risk factors and occupational injuries among building construction workers in Bahir Dar City-Ethiopia.

Ergonomic risk factors are a prominent cause of fatality and severe injuries in building constructions. Hence, this study applies a Structural Equation Modeling (SEM) approach to analyze ergonomics risk factors and occupational injuries among building construction workers in Bahir Dar City, Ethiopia. The results indicate significant relationships between ergonomics risk factors and the prevalence of occupational injuries. This study's findings contribute to the understanding of occupational health and safety in the construction industry, highlighting the need for targeted interventions. A cross-sectional study has been carried out, where data was collected through direct observations and standardized pretested questionnaires. The study recruited 220 participants in the construction industry. The data was analyzed using AMOS to study the direct and indirect effects of the identified variable. SEM has shown that the magnitude of the prevalence of occupational injury was 65.2 %. The results also revealed that the mostly affected body parts were lower arm, lower leg, hand, toe, and knee. Carpenter & roofers, plasterer and daily labors & other helpers were highly injury subjected occupations in respective order. The six leading significant risk factors were, do not tie belt at scaffold, falling stairways & ladders, exposure hazardous substances, tools & machinery, electricity (electric power accidents), repetitive tasks, the layout didn't consider health & safety aspects in the site, and do not provide safety orientation for new workers engaging the job. Employees are mostly affected on their lower body parts which needs more focus to prevent it, especially carpenter & roofers, plasterer and daily labors. Also the findings show that 50 % of respondents agree that the higher priority for safety and health management practices should be given to finishing part of the construction followed by excavation and earth work, masonry, and electrical installations. Therefore, it is recommended that the contractors must focus more on the finishing phase.

'Safety in the Grey Zone': Evaluation of a training program to improve the safety of incident responders on high-speed roads.

INTRODUCTION: Workers operating on high-speed roads (i.e., incident responders and emergency service workers) are at significant risk of being fatally injured while working. An identified gap in current prevention strategies is training focused on developing the skills of workers to effectively communicate and coordinate safety responses when operating on roads. METHODS: This study discusses the development of a program designed to optimize communication and coordination of safety practices at the scene of an incident on a high-speed road. The program is referred to as 'Safety in the Grey Zone.' The goal of the study is to present the results from an evaluation on its implementation across 23 sessions involving 158 participants from 7 incident response agencies in 1 state in Australia. RESULTS: The results of this study provide support for effectiveness in implementing the program as planned. The results also provide preliminary support for effectiveness of the program in achieving its learning outcomes as demonstrated by feedback received from participants following completion of the program. CONCLUSIONS: The findings of this study provide recommendations to consider in the program's future roll-out, as well as suggestions for future evaluations to assess the program's effectiveness in improving the safety of incident responders operating on high-speed roads.

Practice effects of a breathing technique on pilots' cognitive and stress associated heart rate variability during flight operations.

Commercial pilots endure multiple stressors in their daily and occupational lives which are detrimental to psychological well-being and cognitive functioning. The Quick coherence technique (QCT) is an effective intervention tool to improve stress resilience and psychophysiological balance based on a five-minute paced breathing exercise with heart rate variability (HRV) biofeedback. The current research reports on the application of QCT training within an international airline to improve commercial pilots' psychological health and support cognitive functions. Forty-four commercial pilots volunteered in a one-month training programme to practise self-regulated QCT in day-to-day life and flight operations. Pilots' stress index, HRV time-domain and frequency-domain parameters were collected to examine the influence of QCT practice on the stress resilience process. The results demonstrated that the QCT improved psychophysiological indicators associated with stress resilience and cognitive functions, in both day-to-day life and flight operation settings. HRV fluctuations, as measured through changes in RMSSD and LF/HF, revealed that the resilience processes were primarily controlled by the sympathetic nervous system activities that are important in promoting pilots' energy mobilization and cognitive functions, thus QCT has huge potential in facilitating flight performance and aviation safety. These findings provide scientific evidence for implementing QCT as an effective mental support programme and controlled rest strategy to improve pilots' psychological health, stress management, and operational performance.

Standardized Solutions of Catecholamines in Intensive Care Medicine: Application, Safety and Economic Aspects.

Background/Objectives: Catecholamines are among those agents that are indispensable in modern intensive care medicine. The rapid availability of hygienically impeccable and correctly concentrated injectable solutions, e.g., for syringe pumps, is becoming more and more important. However, little research has been conducted regarding how the use of catecholamines is distributed in different wards and what options can be used to achieve optimal availability. Methods: In a retrospective monocentric study from 2019 to 2022, all continuously applied catecholamines in intensive care units (ICU) and intermediate care units (IMC) were investigated. The focus was on potential optimization by utilizing manufactured ready-to-administer solutions in the context of the economization of patient care. Results: Norepinephrine syringes represented 81% of all syringes administered, appearing to be the most frequently used on all wards. Production by the in-house pharmacy showed both financial advantages and an increase in patient safety compared to syringes produced at the bedside. Discussion: Increasing numbers of critically ill patients coupled with growing staff shortages and an increased awareness of safety requirements are driving the move towards ready-to-use and ready-to-administer solutions in critical care medicine. In-house manufacturing by hospital pharmacies can be a promising option to optimize processes and improve the economics of patient care. Conclusions: Individual calculations of the required catecholamine preparations with regard to possible economic advantages should be carried out in hospitals. In particular, in-house production of ready-to-use and ready-to-administer preparations could significantly increase patient safety and seems to be economically viable.

Development of a survey to support assessment of safety learning systems.

BACKGROUND: Patient safety learning systems play a critical role in supporting safety culture in healthcare organisations. A lack of explicit standards leads to inconsistent implementation across organisations, causing uncertainty about their roles and impact. Organisations can address inconsistent implementation by using a self-assessment tool based on agreed-on best practices. Therefore, we aimed to create a survey instrument to assess an organisation's approach to learning from safety events. METHODS: The foundation for this work was a recent systematic review that defined features associated with the performance of a safety learning system. We organised features into themes and rephrased them into questions (items). Face validity was checked, which included independent pre-testing to ensure comprehensibility and parsimony. It also included clinical sensibility testing in which a representative sample of leaders in quality at a large teaching hospital (The Ottawa Hospital) answered two questions to judge each item for clarity and necessity. If more than 20% of respondents judged a question unclear or unnecessary, we modified or removed that question accordingly. Finally, we checked the internal consistency of the questionnaire using Cronbach's alpha. RESULTS: We initially developed a 47-item questionnaire based on a prior systematic review. Pre-testing resulted in the modification of 15 of the questions, 2 were removed and 2 questions were added to ensure comprehensiveness and relevance. Face validity was assessed through yes/no responses, with over 80% of respondents confirming the clarity and 85% the necessity of each question, leading to the retention of all 47 questions. Data collected from the five-point responses (strongly disagree to strongly agree) for each question were used to assess the questionnaire's internal consistency. The Cronbach's alpha was 0.94, indicating a high internal consistency. CONCLUSION: This self-assessment questionnaire is evidence-based and on preliminary testing is deemed valid, comprehensible and reliable. Future work should assess the range of survey responses in a large sample of respondents from different hospitals.

Experience from transport teams on interhospital transfer of patients with extracorporeal membrane oxygenation support: A qualitative study.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) can be a life-saving treatment for patients requiring advanced cardiopulmonary support. Several ECMO centres offer interhospital transport (ECMO IHT) services that involve establishing ECMO teams to initiate ECMO at referring hospitals and then transfer patients to ECMO centres. ECMO IHT is often high risk and complex. Understanding the experience of transport team members is crucial to ensure patient safety and promote quality improvement. AIM: To explore the experiences of transport teams performing ECMO IHT. STUDY DESIGN: A descriptive qualitative methodology was adopted. RESULTS: Thirteen health care professionals who have performed ECMO IHT at a general hospital in China agreed to be interviewed and enrolled in this study. Two investigators conducted face-to-face individual interviews in September-November 2022. All interviews were audio-recorded, transcribed verbatim and analysed using inductive thematic analysis. Three main themes and nine sub-themes were developed: (1) practicing with good organizational management (conducting training programs, cultivating the spirit of good teamwork and developing a standardized transport procedure), (2) dedicated to ensuring patient safety (adequate preparation and regular checking to reduce risk, accurate evaluation to avoid futility and maintaining communication to increase safety) and (3) having confidence despite being uneasy (feeling stressed is common, facing insecurity in transport settings and gaining confidence through practice). CONCLUSIONS: Health care professionals must adequately prepare and assess ECMO IHT to ensure patient safety. Supportive measures should be taken to ensure team members' health and improve patient safety. Good communication and teamwork could improve this challenging task. Further research is required for training programs and establishing standardized transport procedures. RELEVANCE TO CLINICAL PRACTICE: This study presents multi-professional perspectives on the experience of performing ECMO IHT to help management identify what needs to be further developed. With the increasing number of ECMO IHT, promoting its standardization is warranted.

Pediatric nurses' fatigue descriptions in occupational injury reports: A descriptive qualitative study1.

Background: Despite the high risks associated with occupational fatigue in healthcare, few organizations require nurses to screen and report fatigue symptoms. As a result, little is known about if and how nurses would report fatigue while on the job. Objective: To determine if hospital-based pediatric nurses reported fatigue as part of an active injury reporting method. Methods: This secondary analysis of qualitative data used a descriptive design with content analysis. Data from the parent study were collected at a U.S. pediatric hospital where nurses verbally reported on-shift injuries or near misses and pre- and post-shift health status via a digital voice recorder. Researchers used content analysis to independently code data for nurses' references to fatigue. Codes were then analyzed for patterns and themes. Results: Approximately 30% (n = 104) of participants reported fatigue-related content. Emergent themes were Work Stressors, Individual Risk Factors, Fatigue Descriptors, Adverse Outcomes from Fatigue, Fatigue Buffers, Descriptors for Buffered Fatigue, and Favorable Outcomes from Buffered Fatigue. Fatigue descriptions align with prior literature, demonstrating the accuracy of the voice recorder data collection method. In addition, nurses expressed uncertainty about the appropriateness of reporting fatigue symptoms. Conclusion: Findings from this study support pediatric nurses will report fatigue, when provided an opportunity. Additional efforts are needed to better understand effective ways to improve fatigue reporting among nurses, including harnessing current technology for real-time reporting and how to change the culture around fatigue reporting.

Effect of interventions to improve safety culture on healthcare workers in hospital settings: a systematic review of the international literature.

BACKGROUND: In an era of safety systems, hospital interventions to build a culture of safety deliver organisational learning methodologies for staff. Their benefits to hospital staff are unknown. We examined the literature for evidence of staff outcomes. Research questions were: (1) how is safety culture defined in studies with interventions that aim to enhance it?; (2) what effects do interventions to improve safety culture have on hospital staff?; (3) what intervention features explain these effects? and (4) what staff outcomes and experiences are identified? METHODS AND ANALYSIS: We conducted a mixed-methods systematic review of published literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted in MEDLINE, EMBASE, CINAHL, Health Business Elite and Scopus. We adopted a convergent approach to synthesis and integration. Identified intervention and staff outcomes were categorised thematically and combined with available data on measures and effects. RESULTS: We identified 42 articles for inclusion. Safety culture outcomes were most prominent under the themes of leadership and teamwork. Specific benefits for staff included increased stress recognition and job satisfaction, reduced emotional exhaustion, burnout and turnover, and improvements to working conditions. Effects were documented for interventions with longer time scales, strong institutional support and comprehensive theory-informed designs situated within specific units. DISCUSSION: This review contributes to international evidence on how interventions to improve safety culture may benefit hospital staff and how they can be designed and implemented. A focus on staff outcomes includes staff perceptions and behaviours as part of a safety culture and staff experiences resulting from a safety culture. The results generated by a small number of articles varied in quality and effect, and the review focused only on hospital staff. There is merit in using the concept of safety culture as a lens to understand staff experience in a complex healthcare system.

Reconsidering screening thresholds in health assessments for obstructive sleep apnea using operational and safety incident data.

The rail industry in Australia screens workers for probable obstructive sleep apnea (OSA) due to known safety risks. However, existing criteria to trigger screening only identify a small proportion of workers with OSA. The current study sought to examine the relationship between OSA risk and rail incidents in real-world data from Australian train drivers, and conducted a proof of concept analysis to determine whether more conservative screening criteria are justified. Health assessment (2016-2018) and subsequent rail incident data (2016-2020) were collected from two passenger rail service providers. Predictors included OSA status (confirmed no OSA with a sleep study, controlled OSA, unknown OSA [no recorded sleep assessment data] and confirmed OSA with no indication of treatment); OSA risk according to the current Standard, and OSA risk according to more conservative clinical markers (BMI threshold and cardiometabolic burden). Coded rail safety incidents involving the train driver were included. Data were analysed using zero-inflated negative binomial models to account for over-dispersion with high 0 counts, and rail safety incidents are reported using Incidence Risk Ratios (IRRs). A total of 751 train drivers, typically middle-aged, overweight to obese and mostly men, were included in analyses. There were 43 (5.7%) drivers with confirmed OSA, 62 (8.2%) with controlled OSA, 13 (1.7%) with confirmed no OSA and 633 (84.4%) drivers with unknown OSA. Of the 633 train drivers with unknown OSA status, 21 (3.3%) met 'at risk' criteria for OSA according to the Standard, and incidents were 61% greater (IRR: 1.61, 95% Confidence Interval (CI) 1.02-2.56) in the years following their health assessment compared to drivers who did not meet 'at risk' criteria. A more conservative OSA risk status using lower BMI threshold and cardiometabolic burden identified an additional 30 'at risk' train drivers who had 46% greater incidents compared to drivers who did not meet risk criteria (IRR (95% CI) 1.46 (1.00-2.13)). Our more conservative OSA risk criteria identified more workers, with greater prospective incidents. These findings suggest that existing validated tools could be considered in future iterations of the Standard in order to more sensitively screen for OSA.

Effects of a special continuous quality improvement in nursing on the management of adverse care events: a retrospective study.

OBJECTIVE: To explore the application effect of the direct reporting system of adverse nursing events and special continuous nursing quality improvement measures in the management of these adverse events. METHODS: The implementation time of continuous nursing improvement based on the direct reporting system was the demarcation point. We retrospectively collected and analyzed nursing adverse event reports and hospitalization data from Xiangtan Central Hospital before implementation (2015-2018) and after implementation (2019-2022). The active reporting rate of adverse events, the composition of these events and the processing time were compared between the two groups. RESULTS: The rate of active reporting of adverse events before the implementation was lower than that after the implementation (6.7% vs. 8.1%, X2 = 25.561, P < 0.001). After the implementation of the direct reporting system for nursing events and the continuous improvement of nursing quality, the reporting proportion of first-level and second-level events decreased significantly. Moreover, the reporting proportion of third-level events increased significantly. The proportion of falls and medication errors decreased, and the proportion of unplanned extubation, infusion xerostomia and improper operation increased. The processing time of the reported nursing adverse events was significantly reduced (31.87 ± 7.83 vs. 56.87 ± 8.21, t = 18.73, P < 0.001). CONCLUSION: The direct reporting system of adverse nursing events and the continuous improvement measures for nursing quality can effectively improve the active reporting rate of adverse events, change their composition and reduce their processing time, as well as help create a safe psychological environment for both patients and nursing staff.

Risk assessment of healthcare workers' exposure to physical load in relation to patient handling and movement: a feasibility study of the instrument TilThermometer.

BACKGROUND: Work-related musculoskeletal disorders are common among healthcare workers (HCWs) but might be prevented by risk assessment and further promotion of occupational safety and health. The aim of this study was to investigate if the risk assessment instrument TilThermometer can be used to identify risk profiles of physical exposure in HCWs working with patient handling and movement (PHM). Further aims were to describe HCWs' perceptions and experiences of using the TilThermometer. METHODS: This feasibility study has a mixed design methodology. In total, 54 HCWs from 17 Swedish care units participated and performed risk assessments with the TilThermometer. Data collected from the risk assessments were used to identify risk profiles of physical exposure. HCWs' experiences of using the TilThermometer were collected from activity logs and analysed qualitatively. Three questionnaires were used to assess perceived acceptability, appropriateness, and feasibility of the risk assessment, and eight study specific questions were used for perceived usefulness. RESULTS: The TilThermometer was used at the care units by assessing each care recipient, and when compiling the data at a group level, a summarized risk profile for the care unit could be provided. Risk for physical exposure was reported as high in two work tasks; no care unit used the high-low adjustable seat when showering care recipients sitting down, and 13% used the recommended assistive devices when putting compression stockings on. However, 99% used high-low adjustable assistive devices when caring and bathing care recipients lying down. TilThermometer was described as easy to use, enabling team reflections and providing an overview of the care units' recipients and workload, but difficulties in categorizing for mobility groups were also reported. The TilThermometer was, on a five-point scale, perceived as acceptable (mean 3.93), appropriate (mean 3.9), and feasible (mean 3.97). These scores are in line with questions evaluating usefulness. CONCLUSION: The risk assessment provided risk profiles with potential to contribute to care units' development of a safe patient handling and movement practice. The findings suggest that the TilThermometer can be used to assess risks for physical exposure in relation to patient handling and movement in care units at hospital and nursing homes.

Patient Safety Culture: Nurses' Perspective in the Hospital Setting.

(1) Background: Patient safety culture (PSC) encompasses the values, attitudes, norms, beliefs, practices, perceptions, competencies, policies, and behaviours of professionals that determine organisational commitment to quality and patient safety. Few studies use mixed methods to analyse patient safety culture, and none offer the richness of using a mixed methodology to develop their theoretical model. This study aims to identify the factors nurses believe contextualise and influence PSC in relation to existing theoretical frameworks. (2) Methods: This study employed a sequential explanatory mixed-methods design combined with the Pillar Integration Process for data integration. (3) Results: In the final data integration process, 26 factors affecting nurses' PSC were identified. Factors nurses related to PSC not being assessed with the tool used in phase 1 were notification system, flow of patients, patient involvement, resources and infrastructure, and service characteristics. (4) Conclusions: This mixed-methods study provides an opportunity to identify the weaknesses and strengths of currently developed theoretical frameworks related to PSC and offers content for its improvement. Even though multiple studies aim to assess PSC using existing quantitative method tools, the development of this study offers a glimpse of some aspects relevant to nurses' PSC not included in the theoretical framework of the said tools, such as patient involvement, the flow of patients, and service infrastructure.

The World Federation of Chiropractic Global Patient Safety Task Force: a call to action.

BACKGROUND: The Global Patient Safety Action Plan, an initiative of the World Health Organization (WHO), draws attention to patient safety as being an issue of utmost importance in healthcare. In response, the World Federation of Chiropractic (WFC) has established a Global Patient Safety Task Force to advance a patient safety culture across all facets of the chiropractic profession. This commentary aims to introduce principles and call upon the chiropractic profession to actively engage with the Global Patient Safety Action Plan beginning immediately and over the coming decade. MAIN TEXT: This commentary addresses why the chiropractic profession should pay attention to the WHO Global Patient Safety Action Plan, and what actions the chiropractic profession should take to advance these objectives. Each strategic objective identified by WHO serves as a focal point for reflection and action. Objective 1 emphasizes the need to view each clinical interaction as a chance to improve patient safety through learning. Objective 2 urges the implementation of frameworks that dismantle systemic obstacles, minimizing human errors and strengthening patient safety procedures. Objective 3 supports the optimization of clinical process safety. Objective 4 recognizes the need for patient and family engagement. Objective 5 describes the need for integrated patient safety competencies in training programs. Objective 6 explains the need for foundational data infrastructure, ecosystem, and culture. Objective 7 emphasizes that patient safety is optimized when healthcare professionals cultivate synergy and partnerships. CONCLUSIONS: The WFC Global Patient Safety Task Force provides a structured framework for aligning essential considerations for patient safety in chiropractic care with WHO strategic objectives. Embracing the prescribed action steps offers a roadmap for the chiropractic profession to nurture an inclusive and dedicated culture, placing patient safety at its core. This commentary advocates for a concerted effort within the chiropractic community to commit to and implement these principles for the collective advancement of patient safety.

Describing the impact of psychological safety on risk prevention: A threshold model construction.

BACKGROUND: Like other things, psychological safety has a too-much-of-a-good-thing effect on the risk prevention process. There are warranted systematic and theoretical discussions on both positive and negative influences of psychological safety, which provide useful guides to handling potential risks for workers. OBJECTIVE: This study focuses on the psychological safety analysis of work safety for workers in high-risk industries through the construction of a theoretical model, illustrating that a higher level of psychological safety is not better. METHOD: This study explores the impact of workers' psychological safety on the potential risk of work safety by conducting a comprehensive analysis of relevant literature and employing inductive reasoning and analogy methodology. RESULTS: We systematically reviewed the research background and several hypotheses of psychological safety, described the relationship between psychological safety and risk prevention from three levels, and constructed the threshold initial, special, and extended model of psychological safety to reveal the importance of workers' psychological safety when handling potential risks. CONCLUSION: This research effectively describes the influence of high, moderate, and low levels of psychological safety on the risk prevention of work safety, which provides a psychological model guide to developing measures for the improvement of work safety management.

Creation and Administration of a Chiropractic Program Practical Classroom Preparticipation Screening Aimed to Prevent Student Injuries: A Descriptive Report.

Objective: The purpose of this descriptive report is to describe the development of a preparticipation risk assessment screening process for incoming students prior to participation in practical labs. Methods: A committee at the Palmer College of Chiropractic, Florida met to discuss a health history questionnaire, physical examination process, and course of action to have second-year students use their current knowledge to screen incoming students for possible clinical considerations of practice lab participation. The aim was to identify potential risk factors that may require application modification associated with performing and receiving adjustments and other hands-on lab activities within the curriculum. The preparticipation screening process, focused on general health and curriculum referenced chiropractic clinical considerations, and was created as an expansion of the existing informed consent procedures to screen incoming students prior to participating in palpation, technique, physical examination, and open adjusting labs in the chiropractic program. Any clinical considerations identified during the screening were referred to be fully evaluated by a third-year clinic intern and faculty-licensed chiropractor to maintain classroom safety standards for the students. Referred students were restricted from full classroom lab participation until recommendations from the clinic or outside licensed healthcare providers managing their concerns were received. Results: The program was implemented in April 2022. Eight out of the 48 students evaluated in the first group and 12 of the 81 in the second group had possible clinical considerations to participation and were referred appropriately for a full evaluation. In the third group, 35 out of 146 students with suspected clinical considerations to participation were identified. Of the 55 students referred out, all students are now actively participating in classroom activities. Fifteen have been cleared to return to classroom participation with no restrictions and the remaining 40 students have been released for participation with patient-specific restrictions as directed by their managing health care providers. Conclusion: The preparticipation screening process was implemented as all incoming students since the inception of the process have been screened, referred for evaluation when deemed appropriate, and cleared to participate in labs either with or without restrictions. This process has also demonstrated the possibility of identifying multiple clinical considerations for safe curricular participation while participating in doctor-patient simulated classroom activities. This process may be helpful for new students to recognize the patient history and examination procedures as an important aspect of a patient encounter prior to receiving treatment.

Grading recommendations for enhanced patient safety in sentinel event analysis: the recommendation improvement matrix.

OBJECTIVES: The goal of sentinel event (SE) analysis is to prevent recurrence. However, the rate of SEs has remained constant over the past years. Research suggests this is in part due to the quality of recommendations. Currently, standards for the selection of recommendations are lacking. Developing a method to grade recommendations could help in both designing and selecting interventions most likely to improve patient safety. The aim of this study was to (1) develop a user-friendly method to grade recommendations and (2) assess its applicability in a large series of Dutch perioperative SE analysis reports. METHODS: Based on two grading methods, we developed the recommendation improvement matrix (RIM). Applicability was assessed by analysing all Dutch perioperative SE reports over a 12-month period. After which interobserver agreement was studied. RESULTS: In the RIM, two elements are crucial: whether the recommendation intervenes before or after an SE and whether it eliminates or controls the hazard. Applicability was evaluated in 115 analysis reports, encompassing 161 recommendations. Recommendation quality varied from the highest, category A, to the lowest, category D, with category A accounting for 44%, category B for 35%, category C for 2% and category D for 19% of recommendations. There was a fair interobserver agreement. CONCLUSION: The RIM can be used to grade recommendations in SE analysis and could possibly help in both designing and selecting interventions. It is relatively simple, user-friendly and has the potential to improve patient safety. The RIM can help formulate effective and sustainable recommendations, a second key objective of the RIM is to foster and facilitate constructive dialogue among those responsible for patient safety.

Development of a scoring system to quantify errors from semantic characteristics in incident reports.

OBJECTIVES: Incident reporting systems are widely used to identify risks and enable organisational learning. Free-text descriptions contain important information about factors associated with incidents. This study aimed to develop error scores by extracting information about the presence of error factors in incidents using an original decision-making model that partly relies on natural language processing techniques. METHODS: We retrospectively analysed free-text data from reports of incidents between January 2012 and December 2022 from Nagoya University Hospital, Japan. The sample data were randomly allocated to equal-sized training and validation datasets. We conducted morphological analysis on free text to segment terms from sentences in the training dataset. We calculated error scores for terms, individual reports and reports from staff groups according to report volume size and compared these with conventional classifications by patient safety experts. We also calculated accuracy, recall, precision and F-score values from the proposed 'report error score'. RESULTS: Overall, 114 013 reports were included. We calculated 36 131 'term error scores' from the 57 006 reports in the training dataset. There was a significant difference in error scores between reports of incidents categorised by experts as arising from errors (p<0.001, d=0.73 (large)) and other incidents. The accuracy, recall, precision and F-score values were 0.8, 0.82, 0.85 and 0.84, respectively. Group error scores were positively associated with expert ratings (correlation coefficient, 0.66; 95% CI 0.54 to 0.75, p<0.001) for all departments. CONCLUSION: Our error scoring system could provide insights to improve patient safety using aggregated incident report data.
