BACKGROUND: Burden of adverse drug reactions (ADRs), in home-environment and domestic settings, is unknown.
OBJECTIVE: To discuss the epidemiology of reported ADRs to 13-Aban drug and poison information center (DPIC) and to discuss the burden of hospitalization caused by these ADRs from commonly implicated therapeutic groups.
METHODS: A retrospective analysis of the yellow card schemes of suspected ADRs reported to the 13-Aban DPIC was conducted from 21 March 2013 to 21 November 2016 inclusive. MAIN OUTCOME MEASURES: Characteristics of the ADRs, such as the sex and age of the patient, the therapeutic group involved, and the medical outcome of the exposure, were examined. ADR Hospitalization (ADRH) index was calculated for each drug group by dividing the number of ADR-related hospitalizations with total number of reported ADR cases (n = 748), and then multiplying by 100.
RESULTS: ADRs were reported for 748 patients representing 5 cases per 1000 enquiries to the 13-Aban DPIC over almost 4-years of the study period. Public were responsible for reporting every 4 out of 5 ADR cases (n = 651, 87%) and the remaining 1 out of 5 ADR cases was reported by the health care professionals (n = 97, 13%). Most of the ADRs had a medical outcome documented as having a minor effect or were minimally bothersome to the patients (n = 509, 68%), and less than 4.9% (n = 37) were documented as having a major effect or were life-threatening. Overall, 7.4% (n = 55) of ADRs were resulted in hospitalization. Antibacterials for systemic use represented the therapeutic group with the highest hospitalization index (1.7%).
CONCLUSIONS: The study concluded that ADRs to antibiotics are common and some of them resulted in hospitalization.
