Background: Nurse engagement and retention are critical issues affecting the quality of healthcare. Although the work environment is known to affect nursing performance and patient outcomes, little is known regarding the impact of this environment on nurse burnout and future work intention, especially in non-Western settings. Purpose: This study explored the extent to which Taiwanese nurses' perceptions of their practice environment mediates burnout levels and intention-to-stay. Methods: This descriptive, correlational study, conducted between September and December 2020, recruited nurses employed at a regional teaching hospital located in a relatively rural region in Taiwan. The participants completed standardized questionnaires, including a demographic information form, the 31-item Practice Environment Scale of the Nursing Work Index (PES-NWI), the 22-item Maslach Burnout Inventory (MBI-HSS), and the 6-item Intention-to-stay (ITS) scale. The mediating effect among the variables related to intention-to-stay was examined using Model 4 of the PROCESS macro and tested using the bootstrapping method (repeated 5,000 times) with a p value < .05. Results: The mean age of the 376 participants was 34.3 years (SD = 8.1). Nearly one-third (30.3%) scored > 27 on the emotional exhaustion subscale of the MBI-HSS, indicating they were "highly burned-out". Also, nearly one-third (30.6%) were uncertain about their intention to stay with their current employer. Burnout was associated with intention-to-stay (β = -.088, p < .001), and holding a positive perception toward their practice environment was shown to mediate the relationship between burnout and intention-to-stay (β = -.015; p < .001). Conclusions/Implications for Practice: Targeted interventions and technical support that promote a collaborative climate and psychological empowerment in clinical practice may alleviate burnout and intention-to-leave in nurses and improve workplace quality.
