Abstract

Background: A great number of studies have been conducted to examine the relationship between nurse staffing and patient outcomes. However, none of the reviews have rigorously assessed the evidence about the effect of nurse staffing on nurse outcomes through meta-analysis. Purpose: The purpose of this review was to systematically assess empirical studies on the relationship between nurse staffing and nurse outcomes through meta-analysis. Methods: Published peer-reviewed articles published between January 2000 and November 2016 were identified in CINAHL, PubMed, PsycINFO, Cochrane Library, EBSCO, RISS, and DBpia databases. Findings: This meta-analysis showed that greater nurse-to-patient ratio was consistently associated with higher degree of burnout among nurses (odds ratio: 1.07; 95% confidence interval [CI]: 1.04–1.11), increased job dissatisfaction (odds ratio: 1.08; 95% CI: 1.04–1.11), and higher intent to leave (odds ratio: 1.05; 95% CI: 1.02–1.07). With respect to needlestick injury, the overall effect size was 1.33 without statistical significance. Discussion: The study findings demonstrate that higher nurse-to-patient ratio is related to negative nurse outcomes. Future studies assessing the optimal nurse-to-patient ratio level in relation to nurse outcomes are needed to reduce adverse nurse outcomes and to help retain nursing staff in hospital settings.
