Healthcare Workers Adherence to Occupational HIV Post-Exposure Prophylaxis and Seroconversion Rate in a Tertiary Health Facility, Southwestern Nigeria
Abstract:
Human Immudeficiency Virus (HIV) transmission
remains a global public health challenge particularly among healthcare workers
(HCWs). HCWs are susceptible to occupational exposures because they often
handle blood and body fluids or contaminated materials. This retrospective
cross-sectional study aimed to determining the HCWs’ HIV exposure
characteristics, adherence to occupational postexposure prophylaxis (PEP) and
seroconversion rate. Information was extracted from all the 114 medical records
of HCWs who sought for PEP at the Obafemi Awolowo University Teaching Hospital
Complex, Ile-Ife, Nigeria, between 2011 and 2023. The data comprised
sociodemographic details, exposure characteristics, adherence to PEP and seroconversion
rate at 6 months. The HCWs age ranged from 20 to 59 years with a mean age of 32.34 ± 8.757 years. The females were 51.8%. Medical
doctors (30.7%) were the most exposed to HIV, follow by the laboratory
scientists 15.8% and nurses 14.9%. Types of exposure were mostly needle stick
injury (80.7%), blood/body fluid splashes (14.9%), and cuts from sharps (4.4%).
Majority of these exposures were high risk, 79%. High proportion of HCWs 85.1%
started PEP within the recommended 72 hours. The study showed low adherence
rate of 67.5%, and poor post-PEP HIV screening. No seroconversion was observed
among the HCWs who completed follow-up. Dolutegravir-based regimen showed
significant association (p=0.026) with improved adherence to PEP. The flaws noticed
in this study should provide bases for the stakeholders and hospital policy
makers to formulate policies that will improve HCWs safety. Hospital
administrators should create more awareness about hospital policies and
procedures when HIV exposure occurs.
