P-231 Near-Commuting Crashes and Its Indirect Relationship With Work-Home Demands via Serial Mediators Among Hospital Nurses: A PLS-Sem Approach

Abstract Introduction Near-commuting crashes among nurses were often underreported. Conversely, commuting crashes involving nurses are becoming more common worldwide. Nurses endure demanding experiences at work and at home. This demand can spill over into other areas of their lives, causing them to become overwhelmed and exhausted. The same phenomenon can occur during commuting, resulting in near-commute crashes or crashes themselves. However, evidence of the complex interplay between work-home demands and near-commuting crashes via serial mediation is limited and confined as a single mediator. This study aims to determine work fatigue (acute and persistent) and unsafe driving behaviours as serial mediators in the relationship between demands (work and home) and near-commuting crashes among hospital nurses. Methods The study employed stratified proportionate random sampling of hospital nurses from 8 tertiary hospitals. The structural equation modelling technique was used to analyse the data, which comprised 436 nurses. Both acute and persistent work fatigue were controlled for age, gender and number of children. Unsafe driving behaviours were controlled for driving skills and commuting impedance. A bias-corrected bootstrap confidence interval was used to determine indirect effects. Results The confidence interval for the indirect effects of work-home demands and near-commuting crashes did not straddle zero indicating a mediating role for work fatigue (acute and persistent) and unsafe driving behaviours. Discussion and conclusion The relationship between work-home demands and commuting crashes via work fatigue and unsafe driving is established. Having an understanding of this mechanism can help stakeholders implement fatigue mitigation interventions at work and modify their driving behaviour to prevent commuting crashes.
