The Determinants of Non-compliance on Rabies Vaccination in North-West Peninsular Malaysia

INTRODUCTION: Rabies post-exposure vaccination (Rabies PEV) remains the most fundamental prevention of human Rabies if administered in a timely and appropriate manner. The study was aimed to determine the proportion and determinants of non-compliance on Rabies PEV among dog bite patients in Perlis, Malaysia from July 2015 to June 2020. METHODS: A retrospective cohort study was conducted using Perlis Rabid Potential Animal Bite Registry data. Independent variables and compliance status were obtained from the registry. Logistic regression analysis was utilized on 507 dog bite patients. RESULTS: Most of dog bite patients were age group of 46–60 years old (23.1%), male (61.3%), Chinese (49.5%), seeking treatment less than 24 h after the exposure (78.3%), category two of exposure (76.3%) and bitten on lower extremities (57.8%) by an owned dog (58.4%). Only 19.5% were non-compliance to Rabies PEV. Siamese had significantly two-timed (AOR: 2.00; 95% CI 1.06, 3.76) odd higher to become non-compliance. Being bitten during 3rd (AOR: 0.27; 95% CI 0.12, 0.59), 4th (AOR: 0.24; 95% CI 0.11, 0.52) and 5th (AOR: 0.20; 95% CI 0.09, 0.44) year of the outbreak had significantly lower odds to non-comply with Rabies PEV. CONCLUSION: 19.5% of dog bite patients still did not comply with the Rabies PEV series. Siamese would likely to non-comply whereas bitten on the 3rd, 4th and 5th years of outbreak less tendency to non-comply. Continuous health promotion to the public in the various languages despite outbreak status are ongoing to improve the perception of risk and benefit toward compliance of Rabies PEV.
