Adverse drug reactions in hospitalized pediatric patients of Saudi Arabian University Hospital and impact of pharmacovigilance in reporting ADR

Abstract

AbstractObjectivesChildren are more vulnerable to ADRs, and this susceptibility is compounded due to hospitalization. There is a lack of local data regarding the potential risk of ADRs in hospitalized pediatric patients. Therefore, this study is designed to identify the frequent nature, severity of adverse drug reactions, drugs implicated and factors influencing ADRs.MethodsIntensive monitoring study of ADRs was done in hospitalized pediatric patients of King Abdulaziz University Hospital, Jeddah from January to December 2011, with an analogous retrospective study for the preceding year to determine incidence rate, demographic aspects, causality appraisal, polypharmacy, body organs/systems involved and drugs implicated in ADR. Comparison of the two data was done to determine the impact of pharmacovigilance.ResultsIncidence rate of ADRs in retrospective study was (4.50%) and (8.2%) in prospective study. ADR was more in patients who received 5–6 drugs, which was (15.5%) in retrospective study and (22.1%) in prospective study. Regarding age, it was the highest in patients of 0–1year of age which was (40.7%) in retrospective study and (38.8%) in prospective study. Anti-infective agents were the most frequently involved in ADR (40.8%) in prospective study and (48.2%) and retrospective study. This study also demonstrated that, there was high susceptibility of the skin to the ADR which was (37%) in retrospective study and (42.9%) in prospective study. None of the ADRs proved to be fatal.ConclusionWell premeditated intensive monitoring approach in pharmacovigilance amplifies the ADR detection, which can persuade healthcare providers into more drug safety
