Examining the pathways by which work-life balance influences safety culture among healthcare workers in Taiwan: path analysis of data from a cross-sectional survey on patient safety culture among hospital staff.

OBJECTIVE

The aim of this study is to examine the pathways by which work-life balance influences safety climate in hospital settings.

DESIGN

A national cross-sectional survey on patient safety culture.

SETTINGS

Healthcare workers from 56 hospitals in Taiwan, covering three work settings: intensive care units, operation rooms and emergency departments.

PARTICIPANTS

14 345 healthcare workers took part in the survey and were included in the present analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

The Safety Attitudes, Maslach's Burn-out Inventory and Work-life balance questionnaires were used to measure patient safety culture, teamwork, leadership, emotional exhaustion and work-life balance. Path analysis was conducted to determine the relationship between work-life balance and safety climate. We tested for mediating and moderating factors influencing this relationship.

RESULTS

The path between work-life balance and safety climate was found to be significant (b=0.32, p<0.001) and explained through a serial mediation. This relationship was found to be mediated by emotional exhaustion followed by teamwork climate in a full mediation. Leadership factors such as identifying as a manager, moderated the indirect pathway between work-life balance and safety climate through teamwork climate (index of moderation: b=0.083, bias corrected 95% CI 0.044 to 0.120) but not through emotional exhaustion or the serial pathway. Subgroup analysis from non-managers on their perception of management was also found to moderate this relationship.

CONCLUSION

We found work-life balance to be associated with safety climate through a fully mediated model. The mediation pathways are moderated by self-identified leadership and perceptions of leadership. Understanding the pathways on how work-life balance influences safety climate provides an explanatory model that can be used when designing effective interventions for implementation in system-based approaches to improve patient safety culture in hospital settings.
