Evolving Factors in Hospital Safety: A Systematic Review and Meta-Analysis of Hospital Adverse Events

A balance of unsafe care incidents and interactive cooperative care: A constructivist grounded theory study of safe care ecosystem for older inpatients

AIMS

To explore older inpatients and their caregivers' care experience and how this relates to the gerontology care practice.

BACKGROUND

Research interest in the conceptualization of safe care for older inpatients was growing, and these studies were predominantly reported from a single or healthcare perspective. There is a shortage of literature on how patients and their caregivers conceptualise safe care.

DESIGN

Constructivist grounded theory.

METHODS

Stage 1 included semi-structured interviews with inpatients. Stage 2 included semi-structured interviews with caregivers and six field notes. Purposive and theoretical sampling were used to recruit 61 participants across six healthcare institutions. Data analysis included initial coding, focused coding, and theoretical coding using constant comparative, field notes and memo writing.

RESULTS

The substantive theory to emerge from the data was A balance of unsafe care incidents and interactive cooperative care. This core concept was informed by four categories: unsafe care incidents, interactive cooperative care, person-centred care, contextual conditions, and one care outcome. The relationships between these categories constituted a balance in which patient-centred care was the core, unsafe care incidents were the barriers, interactive cooperative care was the facilitator, and the result of the balance was the care outcome. The balance constituted a safe care ecosystem under the interaction of contextual conditions.

CONCLUSIONS

Interactive cooperative care is vital in enabling care stakeholders to reduce unsafe care incidents, which facilitates them in achieving safe care and further constructing a healthy care ecosystem.

RELEVANCE TO CLINICAL PRACTICE

This theory identifies barriers and facilitators encountered by care stakeholders to cope with everyday problems and guides them in developing personalised care plans to ensure patient safety.

Patient Harm Events and Associated Cost Outcomes Reported to a Patient Safety Organization

OBJECTIVES

The aims of the study were to describe inpatient harm events detected via an automatic electronic trigger system (ETS) and to consider their financial consequences.

METHODS

Over a 27-month period, inpatient harm events were identified and documented in 1 healthcare system with 37 acute care facilities. Patients who experienced harm (all harm or preventable harm only) were compared with similar patients who did not. Clinical, financial, and demographic data were used to identify labor-adjusted direct variable costs (DVC) and potential differences in length of stay (LOS) associated with all-harm, preventable-harm, and nonharmed cohorts. Age-adjusted Charlson Comorbidity Index, case mix index, diagnosis-related groups, major diagnostic category, sex, age, location, diagnosis, adverse event category and subcategory, preventability, and harm severity were used to compare cohorts. Total harm events reported via the ETS and the health system's voluntary event reporting system were compared.

RESULTS

Nearly 93,000 encounters for all-harm (n = 25,665) and nonharmed cohorts (n = 67,217) were compared by random sampling of diagnosis-related group-matched all-harm and nonharmed groups to ensure similar clinical conditions, as measured by Charlson Comorbidity Index and case mix index. Sampling (2 groups, n = 100 and n = 200) showed that increased LOS was associated with harm; yet other clinical comparators were similar across groups. the preventable-harm subcohort had longer LOS (10.7 versus 5.9 days) and higher DVC ($13,442 versus $8024) than the nonharmed cohort. Identification of harm events was nearly 6-fold higher with the ETS than with the voluntary event reporting system.

CONCLUSIONS

Patients with preventable harm had increased LOS that was associated with higher DVC per preventable-harm encounter in a large US healthcare system.

Nurse judgements of hospitalized patients' safety concerns are affected by patient, nurse and event characteristics: A factorial survey experiment

AIM

To test the influences of patient, safety event and nurse characteristics on nurse judgements of credibility, importance and intent to report patients' safety concerns.

DESIGN

Factorial survey experiment.

METHODS

A total of 240 nurses were recruited and completed an online survey including demographic information and responses to eight factorial vignettes consisting of unique combinations of eight patient and event factors. Hierarchical multivariate analysis was used to test influences of vignette factors and nurse characteristics on nurse judgements.

RESULTS

The intraclass coefficients for nurse judgements suggest that the variation among nurses exceeded the influence of contextual vignette factors. Several significant sources of nurse variation were identified, including race/ethnicity, suggesting a complex relationship between nurses' characteristics and their potential biases, and the influence of personal and patient factors on nurses' judgements, including the decision to report safety concerns.

CONCLUSION

Nurses are key players in the system to manage patient safety concerns. Variation among nurses and how they respond to scenarios of patient safety concerns highlight the need for nurse-level intervention.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

Complex factors influence nurses' judgement, interpretation and reporting of patients' safety concerns.

IMPACT

Understanding nurse judgement regarding patient-expressed safety concerns is critical for designing processes and systems that promote reporting. Multiple event and patient characteristics (type of event and apparent harm, and patient gender, race/ethnicity, socioeconomic status, and communication approach) as well as participant characteristics (race/ethnicity, gender, years of experience and primary hospital area) impacted participants' judgements of credibility, degree of concern and intent to report. These findings will help guide patient safety nurse education and training.

REPORTING METHOD

STROBE guidelines.

PATIENT OR PUBLIC CONTRIBUTION

Members of the public, including patient advocates, were involved in content validation of the vignette scenarios, norming photographs used in the factorial survey and testing the survey functionality.

Enhanced Recovery After Surgery Guidelines and Hospital Length of Stay, Readmission, Complications, and Mortality: A Meta-Analysis of Randomized Clinical Trials

Importance

A comprehensive review of the evidence exploring the outcomes of enhanced recovery after surgery (ERAS) guidelines has not been completed.

Objective

To evaluate if ERAS guidelines are associated with improved hospital length of stay, hospital readmission, complications, and mortality compared with usual surgical care, and to understand differences in estimates based on study and patient factors.

Data Sources

MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central were searched from inception until June 2021.

Study Selection

Titles, abstracts, and full-text articles were screened by 2 independent reviewers. Eligible studies were randomized clinical trials that examined ERAS-guided surgery compared with a control group and reported on at least 1 of the outcomes.

Data Extraction and Synthesis

Data were abstracted in duplicate using a standardized data abstraction form. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias tool. Random-effects meta-analysis was used to pool estimates for each outcome, and meta-regression identified sources of heterogeneity within each outcome.

Main Outcome and Measures

The primary outcomes were hospital length of stay, hospital readmission within 30 days of index discharge, 30-day postoperative complications, and 30-day postoperative mortality.

Results

Of the 12 047 references identified, 1493 full texts were screened for eligibility, 495 were included in the systematic review, and 74 RCTs with 9076 participants were included in the meta-analysis. Included studies presented data from 21 countries and 9 ERAS-guided surgical procedures with 15 (20.3%) having a low risk of bias. The mean (SD) Reporting on ERAS Compliance, Outcomes, and Elements Research checklist score was 13.5 (2.3). Hospital length of stay decreased by 1.88 days (95% CI, 0.95-2.81 days; I2 = 86.5%; P < .001) and the risk of complications decreased (risk ratio, 0.71; 95% CI, 0.59-0.87; I2 = 78.6%; P < .001) in the ERAS group. Risk of readmission and mortality were not significant.

Conclusions and Relevance

In this meta-analysis, ERAS guidelines were associated with decreased hospital length of stay and complications. Future studies should aim to improve implementation of ERAS and increase the reach of the guidelines.

Nurse and Physician Perceptions and Decision Making During Interdisciplinary Communication: Factors That Influence Communication Channel Selection

Errors in decision making and communication play a key role in poor patient outcomes. Safe patient care requires effective decision making during interdisciplinary communication through communication channels. Research on factors that influence nurse and physician decision making during interdisciplinary communication is limited. Understanding influences on nurse and physician decision making during communication channel selection is needed to support effective communication and improved patient outcomes. The purpose of the study was to explore nurse and physician perceptions of and decision-making processes for selecting interruptive or noninterruptive interdisciplinary communication channels in medical-surgical and intermediate acute care settings. Twenty-six participants (10 RNs, 10 resident physicians, and six attending physicians) participated in semistructured interviews in two acute care metropolitan hospitals for this qualitative descriptive study. The Practice Primed Decision Model guided interview question development and early data analysis. Findings include a core category, Development of Trust in the Communication Process, supported by three main themes: (1) Understanding of Patient Status Drives Communication Decision Making; (2) Previous Interdisciplinary Communication Experience Guides Channel Selection; and (3) Perceived Usefulness Influences Communication Channel Selection. Findings from this study provide support for future design and research of communication channels within the EHR and clinical decision support systems.

Patient safety incidents in endoscopy: a human factors analysis of nonprocedural significant harm incidents from the National Reporting and Learning System (NRLS)

BACKGROUND

Despite advances in understanding and reducing the risk of endoscopic procedures, there is little consideration of the safety of the wider endoscopy service. Patient safety incidents (PSIs) still occur. We sought to identify nonprocedural PSIs (nPSIs) and their causative factors from a human factors perspective and generate ideas for safety improvement.

METHODS

Endoscopy-specific PSI reports were extracted from the National Reporting and Learning System (NRLS). A retrospective, cross-sectional human factors analysis of data was performed. Two independent researchers coded data using a hybrid thematic analysis approach. The Human Factors Analysis and Classification System (HFACS) was used to code contributory factors. Analysis informed creation of driver diagrams and key recommendations for safety improvement in endoscopy.

RESULTS

From 2017 to 2019, 1181 endoscopy-specific PSIs of significant harm were reported across England and Wales, with 539 (45.6%) being nPSIs. Five categories accounted for over 80% of all incidents, with "follow-up and surveillance" being the largest (23.4% of all nPSIs). From the free-text incident reports, 487 human factors codes were identified. Decision-based errors were the most common act prior to PSI occurrence. Other frequent preconditions to incidents were focused on environmental factors, particularly overwhelmed resources, patient factors, and ineffective team communication. Lack of staffing, standard operating procedures, effective systems, and clinical pathways were also contributory. Seven key recommendations for improving safety have been made in response to our findings.

CONCLUSIONS

This was the first national-level human factors analysis of endoscopy-specific PSIs. This work will inform safety improvement strategies and should empower individual services to review their approach to safety.

Avoiding adverse events in interventional radiology - a systematic review on the instruments

BACKGROUND

Avoiding AEs is a pivotal fundament for high patient safety in an efficient interventional radiology (IR) department. Although IR procedures are considered to have a lower risk than their surgical alternatives, they account for one third of all radiological adverse events (AEs) and in general, the number of AEs is increasing. Thus, measures to prevent AEs in IR are of interest.

METHODS

A systematic literature search was conducted via handsearch and Ovid. A structured data extraction was performed with all included studies and their quality of evidence was evaluated. Finally, data were aggregated for further statistical analysis.

RESULTS

After screening 1,899 records, 25 full-text publications were screened for eligibility. Nine studies were included in the review. Of those, four studies investigated in simulator training, one in team training, three in checklists, and one in team time-out. Eight were monocenter studies, and five were conducted in a non-clinical context. Study quality was low. Aggregation and analysis of data was only possible for the studies about checklists with an overall reduction of the median error per procedure from 0.35 to 0.06, observed in a total of 20,399 and 58,963 procedures, respectively.

CONCLUSION

The evidence on the instruments to avoid AEs in IR is low. Further research should be conducted to elaborate the most powerful safety tools to improve patient outcomes in IR by avoiding AEs.

Physician-patient race-match reduces patient mortality

This paper assesses the impacts of physician-patient race-match, especially Black patients paired with Black physicians, on patient mortality. We draw on administrative data from Florida, linking hospital encounters from mid-2011 through 2014 to information from the Florida Physician Workforce Survey. Focusing on uninsured patients experiencing unscheduled hospital admissions who are conditionally randomly assigned to physicians, we find that physician-patient race-match for Black patients reduces the likelihood of within-hospital mortality by 0.28 percentage points, a 27 % reduction relative to the overall mortality rate. An alternative identification strategy relying on instrumental variables provides a similar finding.

Patient safety discourse in a pandemic: a Twitter hashtag analysis study on #PatientSafety

Background

The digitalization of medicine is becoming a transformative force in modern healthcare systems. This study aims to investigate discussions regarding patient safety, as well as summarize perceived approaches to mitigating risks of adverse events expressed through the #PatientSafety Twitter hashtag during the COVID-19 pandemic.

Methods

This research is grounded in the analysis of data extracted from Twitter under the hashtag #PatientSafety between December 1, 2019 and February 1, 2023. Symplur Signals, which represents a tool offering a method to monitor tweets containing hashtags registered with the Symplur Healthcare Hashtag Project, was used for analyzing the tweets shared in the study period. For text analytics of the relevant data, we further used the word cloud generator MonkeyLearn, and VOSviewer.

Results

The analysis encompasses 358'809 tweets that were shared by 90'079 Twitter users, generating a total of 1'183'384'757 impressions. Physicians contributed to 18.65% of all tweets, followed by other healthcare professionals (14.31%), and health-focused individuals (10.91%). Geographically, more than a third of tweets (60.90%) were published in the United States. Canada and India followed in second and third positions, respectively. Blocks of trending terms of greater interest to the global Twitter community within the hashtag #PatientSafety were determined to be: "Patient," "Practical doctors," and "Health Care Safety Management." The findings demonstrate the engagement of the Twitter community with COVID-19 and problems related to the training, experience of doctors and patients during a pandemic, communication, the vaccine safety and effectiveness, and potential use of off-label drugs. Noteworthy, in the field of pharmacovigilance, Twitter has the possibility of identifying adverse reactions associated with the use of drugs, including vaccines. The issue of medical errors has been also discussed by Twitter users using the hashtag #PatientSafety.

Conclusion

It is clear that various stakeholders, including students, medical practitioners, health organizations, pharmaceutical companies, and regulatory bodies, leverage Twitter to rapidly exchange medical information, data on the disease symptoms, and the drug effects. Consequently, there is a need to further integrate Twitter-derived data into the operational routines of healthcare organizations.

Increasing a patient's sense of security in the hospital: A theory of trust and nursing action

Having a decreased sense of security leads to unnecessary suffering and distress for patients. Establishing trust is critical for nurses to promote a patient's sense of security, consistent with trauma-informed care. Research regarding nursing action, trust, and sense of security is wide-ranging but fragmented. We used theory synthesis to organize the disparate existing knowledge into a testable middle-range theory encompassing these concepts in hospitals. The resulting model illustrates how individuals are admitted to the hospital with some predisposition to trust or mistrust the healthcare system and/or personnel. Patients encounter circumstances increasing their emotional and/or physical vulnerability to harm, leading to experiences of fear and anxiety. Without intervention, fear and anxiety lead to a decreased sense of security, increased distress, and suffering. Nurse action can ameliorate these effects by increasing a hospitalized person's sense of security or by promoting the development of interpersonal trust, also leading to an increased sense of security. Increased sense of security results in diminished anxiety and fear, and increased hopefulness, confidence, calm, sense of value, and sense of control. The consequences of a decreased sense of security are harmful to patients and nurses should know that they can intervene in ways that both increase interpersonal trust and sense of security.

Effectiveness of nonpharmacological interventions to prevent adverse events in the intensive care unit: A review of systematic reviews

BACKGROUND

Different types of interventions have been assessed for the prevention of adverse events. However, determining which patient-safety practice is most effective can be challenging when there is no systematised evidence synthesis. An overview following the best methodological standards can provide the best reliable integrative evidence.

OBJECTIVES

The objective of this study was to provide an overview of effectiveness nonpharmacological interventions aimed at preventing adverse events in the intensive care unit.

METHODS

A review of systematic reviews (SRs) was conducted according to the Cochrane Handbook and PRISMA recommendations. PubMed, CINAHL, and Cochrane Library were searched for SRs published until March 2022. Two reviewers independently assessed the study's quality, using AMSTAR-2, and extracted data on intervention characteristics and effect on prevention of adverse events.

RESULTS

Thirty-seven SRs were included, and 27 nonpharmacological interventions were identified to prevent 11 adverse events. Most of the reviews had critically low methodological quality. Among all the identified interventions, subglottic secretion drainage, semirecumbent position, and kinetic bed therapy were effective in preventing ventilator-associated pneumonia; the use of earplugs, early mobilisation, family participation, and music in reducing delirium; physical rehabilitation in improving muscle strength; use of respiratory support in preventing reintubation; the use of a computerised physician order entry system in reducing risk of medication errors; and the use of heated water humidifier was effective in reducing artificial airway occlusion.

CONCLUSIONS

Some nonpharmacological interventions reduced adverse events in the intensive care setting. These findings should be interpreted carefully due to the low methodological quality. SRs on preventing adverse events in the intensive care unit should adhere to quality assessment tools so that best evidence can be used in decision-making.

Effects of a management team training intervention on the compliance with a surgical site infection bundle: a before-after study in operating theatres in the Netherlands

OBJECTIVES

To assess the effects of a quality improvement (QI) team training intervention, by measuring the intervention fidelity and the compliance with a surgical site infection (SSI) bundle in the operating theatre (OT).

DESIGN

Multicentre before-after study.

SETTING

This study was performed in four Dutch hospitals.

INTERVENTION

The QI team training intervention consisted of four sessions per hospital and stimulated participants to set culture norms and targets, identify barriers, and formulate management activities to improve compliance with four standard operating procedures (SOPs) of a SSI bundle in the OT. Participants were executive board members, top-level managers, leading clinicians and support staff. The four SOPs were: (1) reducing door movements; (2) preoperative antibiotic prophylaxis prescribing; (3) preoperative shaving; and (4) postoperative normothermia. Poisson and logistic regression analyses were performed to analyse the effect of the intervention on compliance with the individual SOPs (primary outcome measure) and on the influence of medical specialty, time of day the procedure took place and time in the OT (secondary outcome measures).

RESULTS

Not all management layers were successfully involved during all sessions in the hospitals. Top-level managers were best represented in all hospitals, leading clinicians the least. The number of implemented improvement activities was low, ranging between 2 and 14. The team training intervention we developed was not associated with improvements in the compliance with the four SOP of the SSI bundle. Medical specialty, time of day, and time in OT were associated with median number of door movements, and preoperative antibiotic prophylaxis administration.

CONCLUSION

This study showed that after the QI team training intervention the overall compliance with the four SOPs did not improve. Minimal involvement of leading clinicians and a low number of self-initiated activities after the team training were important barriers for compliance.

Incidence and characteristics of adverse events in paediatric inpatient care: a systematic review and meta-analysis

BACKGROUND

Adverse events (AEs) cause suffering for hospitalised children, a fragile patient group where the delivery of adequate timely care is of great importance.

OBJECTIVE

To report the incidence and characteristics of AEs, in paediatric inpatient care, as detected with the Global Trigger Tool (GTT), the Trigger Tool (TT) or the Harvard Medical Practice Study (HMPS) method.

METHOD

MEDLINE, Embase, Web of Science and Google Scholar were searched from inception to June 2021, without language restrictions. Studies using manual record review were included if paediatric data were reported separately. We excluded studies reporting: AEs for a specific disease/diagnosis/treatment/procedure, or deceased patients; study protocols with no AE outcomes; conference abstracts, editorials and systematic reviews; clinical incident reports as the primary data source; and studies focusing on specific AEs only. Methodological risk of bias was assessed using a tool based on the Quality Assessment Tool for Diagnostic Accuracy Studies 2. Primary outcome was the percentage of admissions with ≥1 AEs. All statistical analyses were stratified by record review methodology (GTT/TT or HMPS) and by type of population. Meta-analyses, applying random-effects models, were carried out. The variability of the pooled estimates was characterised by 95% prediction intervals (PIs).

RESULTS

We included 32 studies from 44 publications, conducted in 15 countries totalling 33 873 paediatric admissions. The total number of AEs identified was 8577. The most common types of AEs were nosocomial infections (range, 6.8%-59.6%) for the general care population and pulmonary-related (10.5%-36.7%) for intensive care. The reported incidence rates were highly heterogeneous. The PIs for the primary outcome were 3.8%-53.8% and 6.9%-91.6% for GTT/TT studies (general and intensive care population). The equivalent PI was 0.3%-33.7% for HMPS studies (general care). The PIs for preventable AEs were 7.4%-96.2% and 4.5%-98.9% for GTT/TT studies (general and intensive care population) and 10.4%-91.8% for HMPS studies (general care). The quality assessment indicated several methodological concerns regarding the included studies.

CONCLUSION

The reported incidence of AEs is highly variable in paediatric inpatient care research, and it is not possible to estimate a reliable single rate. Poor reporting standards and methodological differences hinder the comparison of study results.

Patient Voices in Hospital Safety during the COVID-19 Pandemic

Hospitalized patients and their families may be reluctant to express safety concerns. We aimed to describe safety and quality concerns experienced by hospitalized patients and families and factors and outcomes surrounding decisions about voicing concerns, including those related to the COVID-19 pandemic. We conducted semi-structured interviews with 19 discharged inpatients or family members in a qualitative descriptive design. Some participants reported concern about staff competency or knowledge, communication and coordination, potential treatment errors, or care environment. Factors influencing feeling safe included healthcare team member characteristics, communication and coordination, and safe care expectations. Reasoning for voicing concerns often included personal characteristics. Reasons for not voicing concerns included feeling no action was needed or the concern was low priority. Outcomes for voicing a concern were categorized as resolved, disregarded, and unknown. These findings support the vital importance of open safety communication and trustworthy response to patients and family members who voice concerns.

Estonian adverse events study for multimorbid patients using Estonian Trigger Tool (MUPETT-MUltimorbid Patients-Estonian Trigger Tool). Development of Estonian trigger tool for multimorbid patients. A study protocol for mixed-methods study

INTRODUCTION

It is widely recognized that providing healthcare may produce harm to the patient. Different approaches have been developed to measure the burden of adverse events (AEs) to plan and measure the effects of interventions. One of the most widely used instruments is the Trigger Tool, which has previously been modified to be used on various settings and translated into many languages. Multimorbidity complicates care and may increase the number of AEs patients experience. Currently there is no instrument designed to measure AEs in multimorbid patients. In Estonia, there is currently no validated instrument to measure the burden of AEs.

AIMS

The aim of this study will be evaluating the characteristics and ocurrence of AEs in multimorbid patients in hospitalised internal medicine patients of Estonia, and describes the development of a trigger tool for this purpose.

METHODS AND ANALYSIS

We will search for the evidence on measuring AEs in the population of multimorbid patients focusing on trigger tools, and synthesize the data. Data collection of the triggers from the literature will be followed by translating triggers from English to Estonian. An expert multidisciplinary panel will select the suitable triggers for this population. Trigger tool will be pre-tested to assess agreement among professionals and usability of the tool. Validation will be done using 90 medical records. A cross-sectional study in internal medicine departments of two Estonian tertiary care hospitals will be performed to identify the frequency and characteristics of AEs in 960 medical records. We will also provide preventability potential and influencing factors.

DISSEMINATION

Results will be disseminated to healthcare providers and stakeholders at national and international conferences, and as a doctoral medical thesis.

Form for planning and elaborating high fidelity simulation scenarios: A validation study

Every human being has the right to safe, dignified and harm-free care in health institutions. High fidelity simulation has been used in teaching for the training and continuing education of health professionals to promote quality, safe and humanized patient care. Elaborating scenarios is an important phase to provide a simulation-based experience, and is relevant in the teaching-learning process. The objective of this study was to validate the content and applicability of the High Fidelity Simulation Scenario Planning and Development Form and its Operational Manual. The form could be used to development of scenarios to medicine, nursing, physiotherapy and as well as other specialties in the healthcare. This was a methodological validation study of the form and its manual content by experts in simulation and its feasibility, conducted in two phases: Phase 1: eight experts were selected using the “snowball” sampling technique to validate the content measured by the content validity index; Phase 2 (test): the form and its operational manual validated by the experts were made available to 28 participants in order to elaborate scenarios for the feasibility assessment and participation in the focus group. All items in the form and in the operational manual reached a content validity index above 0.80. The total content validity index was 0.98. The evaluation of the usability of the instruments carried out by the participants reached a percentage above 96.43% in all alternatives except for the item “It was easy to use the form to build your scenario” (75%). Eight participants were present in the focus group. Focus group discussions were categorized into completeness, practicality and usefulness according to comments and suggestions. The form and its operational manual proved to be valid instruments.

The role of hospital characteristics in patient safety: a protocol for a national cohort study

BACKGROUND

Substantial expenditures on health care safety programs have been justified by their goal of reducing health care associated-harm (adverse events), but adverse event rates have not changed over the past 4 decades. The objective of this study is to describe hospital-level factors that are relevant to safety in Canadian hospitals and the impact of these factors on hospital adverse events.

METHODS

This is a protocol for a national cohort study to describe the association between hospital-level factors and adverse events. We will survey at least 90 (35%) Canadian hospitals to describe 4 safety-relevant domains, chosen based on the literature and expert consultation, namely patient safety culture, safety strategies, staffing, and volume and capacity. We will retrospectively identify hospital adverse events from a national data source. We will evaluate organization-level factors using established scales and a survey, codesigned by the study team and hospital leaders. Hospital leaders, clinical unit leaders and front-line staff will complete the surveys once a year for 3 years, with an anticipated start date of winter 2022. We will use national health administrative data to estimate the rate and type of hospital adverse events corresponding to each 1-year survey period.

INTERPRETATION

Analysis of data from this project will describe hospital organizational factors that are relevant to safety and help identify organizational initiatives that improve hospital patient safety. In addition to biyearly reports to the leaders of the participating hospitals, we have a multifaceted and tailored dissemination strategy that includes integrating the knowledge users into the study team to increase the likelihood that our study will lead to improved hospital patient safety.
