Mitigating Nurse Turnover in Urban China: Income Inequality and Nurse-Patient Relationships as Moderators of Occupational Stress.

AIM This study examined the moderating effects of income inequality and nurse-patient relationships on the association between occupational stress and nurse turnover intentions in large urban hospitals in China, providing evidence for developing targeted retention strategies. DESIGN A cross-sectional study. METHODS Data from 13,298 nurses in 46 hospitals in Xi'an, China (October-December 2023) were analysed using hierarchical regression to assess associations between occupational stress, organisational and professional turnover intentions and the moderating roles of the expected income achievement rate (calculated as [actual/expected income] × 100%) and nurse-patient relationship quality. RESULTS Eighty-three percent of nurses reported moderate-to-severe occupational stress. Compared to nurses experiencing mild stress, those with moderate/severe stress demonstrated significantly higher organisational and professional turnover intentions. After adjusting for covariates, significant interaction effects were observed. Higher expected income achievement rate showed a modest but significant moderating effect, associated with reduced turnover intentions. While the nurse-patient relationship also moderated this relationship, its protective effect was attenuated under conditions of severe stress. Despite small effect sizes, the consistent patterns and theoretical coherence of these interactions warrant further investigation. CONCLUSION Occupational stress significantly predicts nurse turnover intentions in urban Chinese hospitals, with income inequality and nurse-patient relationship quality serving as modifiable moderating factors. Interventions should integrate equitable compensation, nurse-patient relationship enhancement programmes and stress management initiatives. IMPACT This study demonstrates that equitable income consistently buffers the effects of occupational stress on nurse turnover, while nurse-patient relationships show stress-level-dependent moderation. By implementing region-specific compensation benchmarks and structured communication training, healthcare policymakers can effectively address economic security and relational care quality in workforce stabilisation.
