Analysis of Factors Influencing the Course of Rabies Vaccinations: One Year Study on Compliance of Rabies Vaccination Regimens in Haidian District of Beijing

OBJECTIVE: To identify the factors influencing the completion rate of the course of rabies vaccinations without considering the economic factors or the drug supplies. METHODS: Rabies vaccination data from the Fourth Medical Center of the PLA General Hospital from January 1 to December 31, 2020, were collected. This includes demographics, information on injury-causing animals, vaccination schemes, and injury assessments. Data on completed the course of rabies vaccinations were compared with data on uncompleted. Internal analysis of Zagreb regimen and Essen regimen was performed. The key factor affecting the completion of the course of rabies vaccinations was analyzed. RESULTS: A total of 1633 patients completed the course of rabies vaccinations, while 462 patients did not. There were differences between the two groups in terms of the vaccination scheme, age, and previous history of rabies vaccinations. The results of a multivariate analysis of variance showed that only the vaccination scheme was significantly correlated with the completion rate of the course of rabies vaccinations. The internal analysis of the vaccination schemes showed that the duration of the vaccination scheme directly affected the completion rate of the course of rabies vaccinations, and the vaccination duration was negatively correlated with the completion rate of rabies vaccinations. CONCLUSION: The completion rate of the course of rabies vaccinations with Zagreb regimen was higher than Essen regimen. The completion rate was closely correlated with the vaccination scheme, but the duration of the vaccination scheme was the key factor. There was a linear relationship between the vaccination duration and the completion rate of the course of vaccinations, which can be represented by the following linear equation: the completion rate of the course of rabies vaccinations (%) = 98.342–0.999 × vaccination duration (d). Duration is the critical factor affecting the completion rate. To improve the completion rate of vaccination, it is recommended to use a shorter vaccination duration regimen.
