Predictors of Adverse Events Following Immunization Reporting amongst Healthcare Workers in Jigawa State, Northern Nigeria, 2022
Abstract:
An adverse event following
immunization (AEFI) is any untoward medical occurrence that follows immunization
and does not necessarily have a causal relationship with the usage of the vaccine.
Reporting of AEFI is suboptimal amongst healthcare workers (HWs). This study aimed
to determine predictors of HW’s reporting of AEFI. A descriptive cross-sectional
study was conducted among HWs in selected health facilities (HFs) in Jigawa State
using an open data kit self-administered questionnaire to collect data on socio-demographic
characteristics, training, knowledge, and their practices on AEFI reporting. Analysis
was conducted using Statistical Package for Social Sciences (SPSS) for frequencies,
proportions, and associations using bivariate analysis and multivariate analysis
using logistic regression to determine predictors of AEFI reporting with statistical
significance set at p<0.05 and 95% confidence interval. Of the 400 respondents,
280 (70%) respondents had good knowledge of AEFI, 328(82%) sends routine AEFI reports
and of 212 (53%) who recently encountered an AEFI, 174 (82.1%) exhibited some good
reporting practices. Female gender (AOR 0.46, p=0.035), full-time employees (AOR
0.227, p=0.019), a recent encounter with an AEFI (AOR 3.087, p=0.007) and being
trained on AEFI (AOR 5.54, p=0.011), reporting to elicit training (AOR 2.70, p=0.031)
were predictors of routine reporting from health facility and reporting an encountered
AEFI respectively. Overall, gender, employment status, being trained, and recent
AEFI encounter to elicit training were predictors of AEFI reporting. To improve
reporting of AEFI, there is a need to engage and train health workers on AEFI surveillance.
