Background: Biological splash exposure and sharp injury are the common occupational health -related problems among healthcare workers. Objective: The present study aimed to assess the magnitude of sharp injury, biological splash exposure and associated factors among medical laboratory professionals at public hospitals in Addis Ababa, Ethiopia. Methods: Cross sectional study was conducted in 13 public hospitals found in Addis Ababa, from April 2020 to July 2020. Simple random sampling was used to select participants to respond for the developed structured questionnaire, related with magnitude of biological splash exposure and sharp injury, and associated risk factors. Data analysis was done by using SPSS version 20. The strength of association between dependent and independent variables were computed using an odds ratio with a 95% confidence interval and p value less than or equal to 0.05 was considered as statistically significant. Results: The study was conducted on 294 medical laboratory professionals. The magnitude of sharp injury was 191(65%) and biological splash exposure was 212(72.1%). Sharp injury was 2.97 times more likely to happen among Medical laboratory professionals who had service 5 years and less as compared to those who had 6 years and above(AOR:2.97, 95% CI: 1.18-7.49); Working 40hour/week and below (AOR: 0.51, 95%CI: 0.28-0.92) 0.51 times less likely to be vulnerable to sharp injury as compared to those who were working 40 hours and above 6 ; marital status where being single were 0.48 times less likely to have sharp injury(AOR: 0.48, 95%CI: 0.26-0.90); absence of availability of adequate safety box were 1.95 times more likely to have sharp injury(AOR: 1.95, 95%CI: 1.03-3.69);moreover, attendance seminar or workshop training decrease the risk of sharp injury significantly (AOR: 0.46, 95%CI: 0.24-0.88). On the other hand, biological splash had significant association with: service year of 1-5years (AOR: 3.76, 95%CI: 1.3910.17); working in comfortable work environment (AOR: 0.41, 95%CI: 0.20-0.85); and attending seminar or workshop training (AOR: 0.37, 95%CI: 0.18-0.75); 0.51 times less likely to biological splash. Conclusion: The magnitude of sharp injury was 191(65%) and biological splash exposure was 212(72. 1%).To decrease occurrence of these incidences, it is recommended to strengthened training, discipline in following safety guideline, supplying an adequate safety box and replacing before it is full, proper supervision, avoiding workload are highly recommended.
