Background:
Adverse drug reactions (ADRs) curtail patients' quality of life by virtue of increasing therapeutic complexity and rising multimorbidity. In India, the frequency of ADRs for individual drugs and their economic burdens are rarely evaluated. This study aimed at identifying the incidence and severity of ADRs leading to hospitalization (ADRA) and occurring during a hospital stay (ADRH).
Objective:
The objective of this study is to evaluate the incidence the incidence and severity of ADRs in the ICU and their impact on the duration of hospitalization, along with the cost incurred to treat ADRs in the ICU.
Methods:
Demographic, clinical, and pharmacological data on patients admitted to the ICU were collected, analyzed and evaluated for ADRs. According to the setting analyzed, a descriptive analysis of the reactions, suspected medicines, and associated factors was undertaken.
Results:
A total of 208 patients were admitted to the ICU during the study period, of which ADRA contributed 9.1% of the incidence rate and 8.1% of ADRH in 36 patients. Males had a higher incidence of ADRs than females. Patients who had ADRs had a substantially longer length of stay than those who did not. Electrolyte disturbance was the most commonly found ADR. According to the Hartwig scale and WHO-causality scale, 88.9% were moderate, and 97.2% were possible ADRs, respectively.
Conclusion:
In this study, a similar incidence rate of ADRA and ADRH was observed. The average cost for treating ADRA was higher than that for treating ADRH. As a result, identifying and preventing these reactions is critical, as they cause the patient greater suffering.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
