Worldwide prevalence of inadequate work ability among hospital nursing personnel: A systematic review and meta-analysis

Abstract

Purpose: To estimate the worldwide pooled prevalence of inadequate work ability among hospital nursing personnel using the Work Ability Index (WAI). Design: Systematic review and meta-analysis. Methods: A systematic search was conducted on Medline/PubMed, Scopus, Web of Science, Scielo, PsychInfo, CINAHL, Nursing and Allied Health, LILACS, and Google Scholar from inception to July 2021 to identify observational studies on work abil ity among hospital nursing personnel using the WAI. Two researchers independently completed the study selection, quality assessments, and data extraction on the preva lence of inadequate work ability that was pooled using the random effects model. Finally, subgroup analyses were performed to explore sources of heterogeneity. Findings: A total of 42 studies were included, consisting of 24,728 subjects worldwide from 14 countries. Of these, 35 studies were included in the meta-analytical analyses. The world wide pooled prevalence of inadequate work ability among hospital nursing personnel was 24.7% (95% CI = 20.2%–29.4%). High levels of heterogeneity were detected in all studies. Prevalence was higher in studies where samples were composed of nurses and nursing as sistive personnel (26.8%; 95% CI=22.4%–31.5%) than in those of nurses alone (22.2%; 95% CI = 13.1%–32.9%) and in studies where the sample was over 40 (28.1%; 95% CI = 19.5%– 37.5%) than in those with a sample under that age (22.4%; 95% CI = 15.8%–29.7%). Conclusions: Almost one in four members of hospital nursing staff in the world has inadequate work ability and therefore are at risk of several negative outcomes dur ing their working life. These prevalence data correspond to the pre-pandemic pe riod, so new studies should also be especially useful in quantifying the impact of the COVID-19 pandemic on work ability in the hospital nursing workforce. Clinical relevance: The above findings justify the launch of initiatives that include an nual assessment for the early identification of inadequate work ability, offering the possibility of anticipated corrective measures. Nursing workforce older than 40 years and those belonging to the professional category of nursing assistive personnel should be priority target groups for screening and intervention to improve work ability.
