Prevalence of needle-stick injury in Iranian nurses: an updated systematic review and meta-analysis of observational studies

Abstract

Background: The aim of this study was to conduct a systematic review and meta-analysis to estimate the prevalence of needle-stick injury among Iranian nurses. Methods: We conducted a systematic review and meta-analysis to estimate the prevalence of needle-stick injury among Iranian nurses. A comprehensive search of Web of Science, PubMed, Scopus, Scientific Information Database, and MagIran was performed, yielding 29 observational articles comprising 8842 nurses. The studies ranged from 2006 to 2023, with sample sizes varying from 68 to 1555 individuals. Methodological quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. The pooled prevalence was calculated using the random-effects model, and subgroup analyses were conducted based on hospital type and gender. The data was analyzed using Stata software version 16. Results: The pooled prevalence of needle-stick injury among Iranian nurses was found to be 46% (95% Confidence Interval [CI]: 39-53%). Subgroup analysis revealed significant difference in prevalence between teaching hospitals (47%; 95% CI: 39-54%) and military hospitals (38%; 95% CI: 31.1-44%). The prevalence of NSI in region 1 (Tehran and surrounding provinces) and other regions was 45.1% (95% CI: 37-54%) and 49.17% (95% CI: 36.5-61.7%). Gender-based analysis showed higher prevalence in women (58%; 95% CI: 44-71%) compared to men (55%; 95% CI: 43-66%). Conclusion: Needle stick injuries has a high prevalence among Iranian nurses, especially nurses working in teaching hospitals. Therefore, it seems necessary to use interventions to reduce it.
