Pharmacovigilance study in geriatric patients of a tertiary care hospital
Introduction: The aim was to assess, categorize and analyze the adverse drug reactions among geriatric patients in a tertiary care hospital.
Methods: All adverse drug reactions of geriatric patients reported at the Adverse Drug Reaction Monitoring Center, Sri Venkateswara Medical College, Tirupati, under the Pharmacovigilance programme of India, during September 2016 and January 2018 were identified and evaluated. A retrospective analysis was carried out for ADR pattern, drug groups, organ systems implicated in suspect ADR, demographic profile, causality (as per the WHO–UMC scale), severity (Hartwig and Seigel scale), and preventability (Schumock and Thornton criteria) of a said drug.
Results: A total of 120 ADRs were received among geriatric patients. Most of the ADRs occurred in male geriatrics (55.83 %) and (34.2 %) occurred in the age group of 60- 64 years. Antibiotics comprised the major group of drugs causing ADRs (18.3 %). ADRs related to gastrointestinal systems were most common with 31.7 % followed by skin disorders (15 %) and central nervous system disorders (13.3 %). As per the causality assessment scale, the majority of adverse drug reactions were found to be possible (51.7 %).
Conclusions: There were 60.8 % of reactions being mild and 39.2 % were moderate reactions as per severity scale. The majority of the adverse drug reactions were non-serious (33 %) and in the serious category, 27.5 % of ADRs required intervention to prevent permanent damage.
