Assessing the impacts of nurse staffing and work schedules on nurse turnover: A systematic review

Abstract

AimThis study aimed to investigate and synthesize the impacts of nurse staffing and work schedules on nurse turnover in acute hospitals.BackgroundThe retention of nurses during the COVID‐19 pandemic was critical due to the increased demand for nurses. Among the multifaceted factors contributing to nurse turnover, it is worth examining nurse staffing and work schedules while considering policy intervention.MethodsThe findings of this systematic literature review were reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines. Using eight databases, including CINAHL and PubMed, research articles published from January 2000 until June 2021 were reviewed. The inclusion criteria were original peer‐reviewed research, nonexperimental studies published in English or Korean languages, and studies examining the impacts of nurse staffing and work schedules on nurses’ actual turnover.ResultsFourteen articles were reviewed. Among them, 12 studies investigated the relationship between nurse staffing and turnover, and four examined the impact of work schedules on nurse turnover. Nurse staffing levels are strongly related to nurse turnover in the expected direction. However, few studies have found that work schedules are significantly related to nurse turnover.ConclusionInadequate and unsafe nurse staffing leads to increased nurse turnover rates. More studies are needed to investigate the impacts of work schedules on nurse turnover.Implications for nursing, health, and social policySeveral states in the United States have adopted the nurse staffing policy during the COVID‐19 pandemic. More hospitals and the government should adopt and implement policies to regulate nurse staffing, reduce nurse turnover, and increase retention. Policy intervention in nurse work schedules should also be considered to prevent nurse turnover.
