Barriers to healthcare workers reporting adverse events following immunization in four regions of Ghana

Abstract Despite didactic training on adverse events following immunization (AEFI) in Ghana, the reporting ratio of AEFI was 1.56 per 100,000 surviving infants in 2015, below the minimum reporting ratio of 10. We aimed to estimate the proportion of health care workers (HCWs) reporting AEFI and to identify barriers to reporting. We conducted a cross-sectional survey of HCWs in four regions in Ghana. A simple random sample of 176 health facilities was selected and up to two HCWs were randomly selected per facility. We used the Rao-Scott Chi-squared test to compare factors associated with reporting of AEFI in the last year. We used an open-ended question to identify reasons for low reporting. One supervisor from each facility, responsible for overall reporting and management of AEFI, was also interviewed. A total of 306 HCWs from 169 facilities were interviewed. Of these, 176 (57.5%) reported they had ever encountered an AEFI. Of the 120 who had encountered an AEFI in the last year, 66 (55.0%) indicated they had reported the AEFI, and 38 (31.7%) completed a reporting form. HCWs (n = 120) reported multiple barriers to reporting of AEFI; the most common barriers were fear of personal consequences (44.1%), lack of knowledge or training (25.2%), and not believing an AEFI was serious enough to report (22.2%). Discussion of AEFI during the last supervisory visit was significantly associated with reporting in the past year (OR 7.39; p  We identified low reporting of AEFI and multiple barriers to reporting among HCWs in the four selected regions of Ghana. Discussing AEFI during supervisory visits with HCWs might improve reporting. Additionally, strategies to address fear of personal consequences as a barrier to reporting of AEFI are needed.
