Abstract
Poor sleep quality is a significant problem among shift nurses that leading anxiety, depression, and burnout. Understanding these associations is important since psychological distress will impact a nurse's performance, patient safety, and long-term ability. This systematic review examines the impact of sleep quality to psychological outcomes among nurses in hospital. The approach used systematic review design to reach the objective of the review. The review used a PRISMA flow diagram to transparently and systematically document the process of identifying, screening, and selecting articles. The research question is formulated based on the PICO guidelines. A systematic search of the literature between 2019–2024 was conducted across online databases such as Scopus, ScienceDirect, Web of Science, and Google Scholar. Screening for study quality was completed by using Joanna Briggs Institute (JBI) Critical Appraisal Checklist. A total of 1,245 articles were obtained through screening and a detailed review of the full text. The analysis comprised 19 studies from the various journals (n=7,391 nurses). The review highlighted that poor sleep quality ranged from a high of 94.5% to a low of 16.6%; the majority were emergency department nurses. Work-related stress, occupational patterns, and personal obligations were themes contributing to fatigue, anxiety, and depression. The results indicate a significant negative relationship between sleep quality and psychological outcomes for nurses. Interventions to enhance sleep quality and manage stress are critical for nurses. Furthermore, healthcare policymakers and hospital directors can develop more effective responses to address the psychological impact of shift work on healthcare workers. Increasing the number of incentives for nurses may help reduce the burden of working shifts.
