Influence of nurse work environment and psychological distress on resignation from hospitals: a prospective study.

ABSTRACT

With the global nurse shortage, identifying nurse work environments that allow nurses to continue working is a common concern worldwide. This study examined whether a better nurse work environment (1) is associated with reducing nurses' psychological distress; (2) reduces nurse resignations; (3) weakens the influence of psychological distress on their resignation through interaction effect; and (4) whether psychological distress increases nurse turnover. Multilevel logistic regression analyses were performed using data obtained in 2014 from 2,123 staff nurses from a prospective longitudinal survey project of Japanese hospitals. The nurse work environment was measured by the Practice Environment Scale of the Nursing Work Index (PES-NWI) consisting of five subscales and a composite, and psychological distress by K6. All the PES-NWI subscales and composite (ORs 0.679-0.834) were related to K6, significantly. Regarding nurse turnover, K6 had a consistent effect (ORs 1.834-1.937), and only subscale 2 of the PES-NWI had a direct effect (OR 0.754), but there was no effect due to the interaction term. That is, (1) and (4) were validated, (2) was partly validated, but (3) was not. As better work environment reduces K6 and a lower K6 decreases nurses' resignation, high-level hospital managers need to continue improving the nurse work environment.
