Occupational needle stick injuries and related factors among healthcare workers in military hospitals in Tehran

Abstract

Aim: Healthcare workers (HCWs) are always at risk of experiencing occupational needle stick injuries (NSIs). The primary aim of this study was to assess the prevalence of NSIs among Iranian HCWs in military hospitals in Tehran.

Design: This cross-sectional study was conducted in four military hospitals in the summer of 2019 in Tehran.

Method: By Census, 802 HCWs were included. Data were collected through a questionnaire consisting of vaccination history, safety equipment, use of safety box, history of NSIs and demographic variables. The logistics regression was used to estimate the odds ratios (OR) and 95% confidence interval (CI). The statistical significance level was set at 5%. The data were analysed using the SPSS software version 23.

Results: A total of 203 (25.3%, CI: 22.3-28.4) of the participants reported a history of NSIs at least once during the past year. Single HCWs had a higher risk of NSIs compared to married HCWs (OR: 1.59, 95% CI (1.09, 2.30)). Also, the night shift working (OR: 1.91, 95% CI (1.18, 3.12)), higher educational degree (OR: 2.25, 95% CI (1.21, 4.20)), working overtime (OR: 1.50, 95% CI: (1.07, 2.12)), older age (OR: 1.02, 95% CI (1.01, 1.04)) and needle recapping (OR: 2.90, 95% CI: (1.98, 4.22)) were identified as significant associated factors. The study draws attention to a relatively high prevalence of NSIs as well as high-risk activities among military HCWs. The primary source of NSIs is needle recapping. Measures such as setting up training courses for the military HCWs are needed to be planned.
