Global prevalence of nursing burnout syndrome and temporal trends for the last 10 years: A meta-analysis of 94 studies covering over 30 countries.

Abstract

To determine the global prevalence of nursing burnout syndrome and time trends for the last 10 years. The prevalence of burnout syndrome varied greatly in different regions in the last 10 years, so the average prevalence and time trends of nursing burnout syndrome for the last 10 years were not completely clear. A meta-analysis conducted in the PRISMA guidelines. CINAHL, Web of Science, and PubMed were searched for trials on the prevalence of nursing burnout syndrome from 2012 to 2022 systematically. Hoy's quality assessment tool was used to evaluate the risk of bias. The global prevalence of nursing burnout syndrome was estimated, and subgroup analysis was used to explore what caused heterogeneity. Time trends for the last 10 years were evaluated by meta-regression using Stata 11.0. Ninety-four studies reporting the prevalence of nursing burnout were included. The global prevalence of nursing burnout was 30.0% [95% CI: 26.0%-34.0%]. Subgroup analysis indicated that the specialty (p < .001) and the region (p < .001) and the year (p < .001) were sources of the high heterogeneity. Meta-regression indicated that it tended to increase gradually for the last 10 years (t = 3.71, p = .006). The trends increased in Europe (t = 4.23, p = .006), Africa (t = 3.75, p = .006) and obstetrics (t = 3.66, p = .015). However, no statistical significance was found in ICU (t = -.14, p = .893), oncology (t = -0.44, p = .691) and emergency department (t = -0.30, p = .783). A significant number of nurses were found to have moderate-high levels of burnout syndrome for the last 10 years. The meta-analysis also indicated an increased trend over time. Therefore, more attention to the prevalence of nursing burnout syndrome is urgently required. High prevalence of nursing burnout may attract more attention from the public. This analysis may serve as an impetus for relevant policy to change nurses' working conditions and reduce the occurrence of burnout.
