Objective To carry out a systematic review of the psychometric properties of international studies that have used the Hospital Survey on Patient Safety Culture (HSPSC). Design Literature review and an analysis framework to review studies. Setting Hospitals and other healthcare settings in North and South America, Europe, the Near East, the Middle East and the Far East. Data sources A total of 62 studies and 67 datasets made up of journal papers, book chapters and PhD theses were included in the review. Primary and secondary outcome measures Psychometric properties (eg, internal consistency) and sample characteristics (eg, country of use, participant job roles and changes made to the original version of the HSPSC). Results Just over half (52%) of the studies in our sample reported internal reliabilities lower than 0.7 for at least six HSPSC dimensions. The dimensions ‘staffing’, ‘communication openness’, ‘non-punitive response to error’, ‘organisational learning’ and ‘overall perceptions of safety’ resulted in low internal consistencies in a majority of studies. The outcomes from assessing construct validity were reported in 60% of the studies. Most studies took place in a hospital setting (84%); the majority of survey participants (62%) were drawn from nursing and technical staff. Forty-two per cent of the studies did not state what modifications, if any, were made to the original US version of the instrument. Conclusions While there is evidence of a growing worldwide trend in the use of the HSPSC, particularly within Europe and the Near/Middle East, our review underlines the need for caution in using the instrument. Future use of the HSPSC needs to be sensitive to the demands of care settings, the target population and other aspects of the national and local healthcare contexts. There is a need to develop guidelines covering procedures for using, adapting and translating the HSPSC, as well as reporting findings based on its use.

Promoting patient and occupational safety are two key challenges for hospitals. When aiming to improve these two outcomes synergistically, psychosocial working conditions, leadership by hospital management and supervisors, and perceptions of patient and occupational safety climate have to be considered. Recent studies have shown that these key topics are interrelated and form a critical foundation for promoting patient and occupational safety in hospitals. So far, these topics have mainly been studied independently from each other. The present study investigated hospital staffs’ perceptions of four different topics: (1) psychosocial working conditions, (2) leadership, (3) patient safety climate, and (4) occupational safety climate. We present results from a survey in two German university hospitals aiming to detect differences between nurses and physicians. We performed a cross-sectional study using a standardized paper-based questionnaire. The survey was conducted with nurses and physicians to assess the four topics. The instruments mainly consisted of scales of the German version of the COPSOQ (Copenhagen Psychosocial Questionnaire), one scale of the Copenhagen Burnout Inventory (CBI), scales to assess leadership and transformational leadership, scales to assess patient safety climate using the Hospital Survey on Patient Safety Culture (HSPSC), and analogous items to assess occupational safety climate. A total of 995 completed questionnaires out of 2512 distributed questionnaires were returned anonymously. The overall response rate was 39.6%. The sample consisted of 381 physicians and 567 nurses. We found various differences with regard to the four topics. In most of the COPSOQ and the HSPSC-scales, physicians rated psychosocial working conditions and patient safety climate more positively than nurses. With regard to occupational safety, nurses indicated higher occupational risks than physicians. The WorkSafeMed study combined the assessment of the four topics psychosocial working conditions, leadership, patient safety climate, and occupational safety climate in hospitals. Looking at the four topics provides an overview of where improvements in hospitals may be needed for nurses and physicians. Based on these results, improvements in working conditions, patient safety climate, and occupational safety climate are required for health care professionals in German university hospitals – especially for nurses.

Inter-professional teamwork is a prominent factor in quality of care and may lead to improved patient safety. Although team members’ points of view are highly relevant when trying to improve inpatient procedures, there is a lack of systematic assessment of their perceptions. Therefore, study aims were to explore inter-professional teamwork, safety-related behavior, and patient safety in German hospitals from team members’ point of view. Furthermore, we wanted to examine the association between inter-professional teamwork and safety-related behavior as well as the association between inter-professional teamwork and patient safety. We used cross-sectional pre-intervention data of a multicenter longitudinal study (German KOMPAS project). We gathered descriptive statistics for sample characteristics and to describe the current state of inter-professional teamwork, safety-related behavior, and patient safety. We used one-way variance analyses to assess differences between groups, and linear regression analyses to examine the association between inter-professional teamwork and the outcomes safety-related behavior, and patient safety. 326 inpatient care team members participated in the study. Participants perceived a moderate to high level of inter-professional teamwork, and a moderate level of patient safety. Moreover, they reached rather high values in safety-related behavior. Professional group, work experience, and period of employment had an impact on the perceptions of inter-professional teamwork, and patient safety. Higher inter-professional teamwork was associated with better patient safety. We did not find an association between inter-professional teamwork and safety-related behavior. Based on the association between inter-professional teamwork and patient safety, we recommend the implementation of team interventions. Because professional group, period of employment, and work experience had an impact on the perceptions of inter-professional teamwork and patient safety, we suggest future qualitative research to explore reasons for caregivers’ critical evaluation. Moreover, we recommend longitudinal studies to reveal causal relationships, and subsequently to determine areas of improvement for a safer health care.

Background: Many hospitals seek to increase patient safety through interprofessional team-trainings. Accordingly, these trainings aim to strengthen important key aspects such as safety culture and communication. This study was designed to investigate if an interprofessional team-training, administered to a relatively small group of nurses and physicians would promote a change in healthcare professionals’ perceptions on safety culture and communication practices throughout the hospital. We further sought to understand which safety culture aspects foster the transfer of trained communication practices into clinical practice. Methods: We conducted a pre-post survey study using six scales to measure participants’ perceptions of safety culture and communication practices. Mean values were compared according to profession and participation in training. Using multiple regression models, the relationship between safety culture and communication practices was determined. Results: Before and after the training, we found high mean values for all scales. A significant, positive effect was found for the communication practices of the physicians. Participation in the training sessions played a variably relevant role in the communication practices. In addition, the multiple regression analyses showed that specific safety culture aspects have a cross-professional influence on communication practices in the hospital. Conclusions: This study suggest that interprofessional team-trainings of a small group of professionals can successfully be transferred into clinical practice and indicates the importance of safety culture aspects for such transfer processes. Thus, we recommend the consideration of safety culture aspects before starting a training intervention.

Background: In the healthcare sector, a comprehensive safety culture includes both patient care-related and occupational aspects. In recent years, healthcare studies have demonstrated diverse relationships between aspects of psychosocial working conditions, occupational, and patient safety culture. The aim of this study was to consider and test relevant predictors for staff’s perceptions of occupational and patient safety cultures in hospitals and whether there are shared predictors. From two German university hospitals, 381 physicians and 567 nurses completed a questionnaire on psychosocial working conditions, occupational, and patient safety culture. Two regression models with predictors for occupational and patient safety culture were conceptually developed and empirically tested. In the Occupational Safety Culture model, job satisfaction (β = 0.26, p ≤ 0.001), work‒privacy conflict (β = −0.19, p ≤ 0.001), and patient-related burnout (β = −0.20, p ≤ 0.001) were identified as central predictors. Important predictors in the Patient Safety Culture model were management support for patient safety (β = 0.24, p ≤ 0.001), supervisor support for patient safety (β = 0.18, p ≤ 0.001), and staffing (β = 0.21, p ≤ 0.001). The two models mainly resulted in different predictors. However, job satisfaction and leadership seem to play an important role in both models and can be used in the development of a comprehensive management of occupational and patient safety culture.

Objectives: In recent years, several instruments for measuring patient safety culture (PSC) have been developed and implemented. Correct interpretation of survey findings is crucial for understanding PSC locally, for comparisons across settings or time, as well as for planning effective interventions. We aimed to evaluate the influence of gender, profession, and managerial function on perceptions of PSC and on the interplay between various dimensions and perceptions of PSC. Methods: We used German and Swiss survey data of frontline physicians and nurses (n = 1786). Data analysis was performed for the two samples separately using multivariate analysis of variance, comparisons of adjusted means, and series of multiple regressions. Results: Participants’ profession and managerial function had significant direct effect on perceptions of PSC. Although there was no significant direct effect of gender for most of the PSC dimensions, it had an indirect effect on PSC dimensions through statistically significant direct effects on profession and managerial function. We identified similarities and differences across participant groups concerning the impact of various PSC dimensions on Overall Perception of Patient Safety. Staffing and Organizational Learning had positive influence in most groups without managerial function, whereas Teamwork Within Unit, Feedback & Communication About Error, and Communication Openness had no significant effect. For female participants without managerial functions, Management Support for Patient Safety had a significant positive effect. Conclusions: Participant characteristics have significant effects on perceptions of PSC and thus should be accounted for in reporting, interpreting, and comparing results from different samples.
