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 ability among hospital nursing personnel using the WAI. Two researchers independently completed the study selection, quality assessments, and data extraction on the prevalence 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 worldwide 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 assistive 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 during their working life. These prevalence data correspond to the pre-pandemic period, 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 annual assessment for the early identification of inadequate work ability, offering the This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.

Aim: To define the competencies of nurse anaesthetists in the hospitals of Catalonia on the basis of their clinical practice through a consensus-building process. Design:We used the Delphi method to determine consensus among a group of 16 nurse anaesthetists. Methods:Between February and June 2020, we administered a questionnaire of 142 questions distributed among seven domains: expert, communicator, collaborator, manager, health advocate, scholar and professional. Two rounds were conducted. Results:In round 1, 18 competencies were discarded and nine had inconclusive results. Eighteen competencies were proposed by participants. The nine competencies with inconclusive results and the 18 newly proposed competencies were considered in round 2. In round 2, three of these 27 competencies tested were discarded, and consensus was reached on the other 24. Conclusion:Health education and the empowerment of the patient and family are fundamental pillars in the practice of nurse anaesthetists in Spain, especially in pre-anaesthetic assessment and pain care. These areas of practice can help define competencies in other countries where the profession of nurse anaesthetist is less developed. Impact:The lack of regulation of the competencies of nurse anaesthetists leads to great variability in training and practice. The results can help in their standardization in Spain and in other countries lacking regulation. Our approach can also help policymakers and hospital administrators in health systems that are undergoing the process of regulation. The regulation of the competencies of nurse anaesthetists will allow them to contribute their expertise to the health-illness continuum, increasing safety and improving the quality of care.
