Abstract
Aim
To find the incidence rate of adverse drug reactions (ADRs) and investigate its various aspects in patients admitted to surgery wards of a rural tertiary-care hospital in India.
Methodology
A prospective observational study, involving 800 patients over a period of 1.5 years, was carried out to find the incidence rate of ADRs, and various aspects of such events (e.g. causality, severity, preventability, causative drugs, organs/systems involved, and management strategy with outcome). A structured and pre-tested form was used to compile the data.
Results
An ADR was reported in 3.9 % of patients. Neither the age nor gender of the patients influenced incidence rate. Type A (augmented) reactions accounted for 83.9 % of ADRs. Causality assessment, using the WHO-UMC method, revealed that 58.1 and 41.9 % of ADRs fell into the ‘probable’ and ‘possible’ categories, respectively, whereas the corresponding proportions were 71.0 and 29.0 % using the Naranjo ADR probability scale. As the number of drugs per patient increased, the incidence of ADRs also increased. The majority (77.4 %) of ADRs were associated with antimicrobial drugs, followed by analgesics, with 71 % of ADRs involving the gastrointestinal system. No ADRs were fatal. Suspected drugs were discontinued in 64.5 % of patients and 96.8 % patients had fully recovered at the time of discharge.
Conclusion
Identification and monitoring of ADRs among various patient groups, including those admitted to general surgical wards of a hospital, along with meticulous reporting thereof, can help provide better and more rational patient care. Few studies that monitored ADRs in surgical patients are available. The incidence rate of ADRs amongst surgical patients in this Indian hospital appears to be much lower than commonly reported (3.9 vs. 10–25 %).
