EVALUATION OF ADVERSE DRUG REACTIONS IN A TERTIARY CARE CENTER IN SOUTH INDIA-A PROSPECTIVE OBSERVATIONAL STUDY
Aim:To Evaluate the Adverse Drug Reactions among patients attending a tertiary care centre. Materials and Methods: Aprospective spontaneous reporting method of Adverse Drug Reaction (ADR) in hospitalised setting was conducted for a period of six months. Results: The study came across with the demography of patients, the most commonly involved classes of drugs and assessment of ADRs. The results showed that 136 adverse drug reactions were reported from a total of 11584 patients and the overall incidence of ADR calculated from patient population was 0.81%. No signicant difference was seen in overall incidence of ADRs observed in males and females. Incidence of ADRs among adults (1.15%) was signicantly higher than paediatrics and geriatrics. Antibiotics (39.71%) were the drug class most commonly associated with ADRs. Causality assessment states that majority of the reported ADRs were probable according to WHO-UMC criteria. According to the severity assessment majority of the ADRs were mild in nature. Most of the ADRs were not preventable (76.47%) according to Schumock and Thornton preventability scale. Conclusion: ADR monitoring was found to be useful to measure the effectiveness and safe use of medication.
