Abstract

Incidence of adverse drug reactions [ADRs] leads to many conflicting discussions about patients safety in many countries. It has been shown that ADRs are more frequent in outpatient department rather than indoors. We wanted to find out if there is similar situation in Morocco as well. Due to lack of National data we investigated the incidence of ADRs in patients of teaching hospital Ibn Sina in Rabat. Out of the total number of patients who attended the above hospital during study period of 5 days in February. Sample size 644. 113[17.54%] patients developed at least one ADR [nearly 1.47ADR/per patient]. Out of these patients 4 patients were hospitalized as a direct result of ADR. ADRs were more common in female patients then males. Maximum ADRs occurred in the age bracket of 40-49 years. Maximum cases were recorded from Pnumology service. Large size and longer study period is required to get answer to our question.

Key words: Adverse drug reaction, serious adverse drug reactions, rate prevalence, transversal study, outpatients.
