Factors associated with occupational needle stick and sharps injuries among hospital healthcare workers in Bale zone, Southeast Ethiopia

Background: Needle stick and sharps injuries are occupational hazards to healthcare workers. Every day healthcare workers are exposed to deadly blood borne pathogens through contaminated needles and other sharp objects. About twenty blood borne pathogens can be transmitted through accidental needle stick and sharp injury. The study was conducted to determine the lifetime and past one year prevalence of needle stick and sharps injuries and factors associated with the past one year injuries among hospital healthcare workers in Southeast Ethiopia.

Methods: An institutional based cross sectional study was conducted in December 2014 among healthcare workers in four hospitals of Bale zone, Southeast of Ethiopia. A total of 362 healthcare workers were selected randomly from each department in the hospitals. Data were collected using self-administered questionnaire. The collected data were entered into Epi-Info version 3.5 and analyzed using SPSS version 20.0. Multivariable logistic regression analysis was used to identify the independent effect of each independent variable on the outcome variable. Written informed consent was secured from the participants.

Results: The prevalence of lifetime needle stick and sharp injury was 37.1% with 95% CI of 32.0% to 42.5%. The prevalence of injury within the past one year was 19.1% with 95% CI of 14.9% to 23.3%. Emergency ward was a department with highest needle stick and sharp injury (31.7%). The main cause of injury was syringe needles (69.8%). Participants who practiced needle recapping had higher odds of needle stick and sharp injury within the past 12 months (AOR = 3.23, 95% CI: 1.78, 5.84) compared to their counterparts.

Conclusions: Nearly one out of five respondents had experienced needle stick and/or sharp injury at least once within past one year. There were practices and behaviors that put healthcare workers at risk of needle stick and sharp injury at the study area. Needle recapping was key modifiable risk behavior. Health policy makers and hospital administrators should formulate strategies to improve the working condition for healthcare workers and increase their adherence to universal precautions.
