Pharmaco-epidcemiology of drugs utilised for cataract surgery in a government medical college and hospital.

Prescription audit is a powerful tool for rational prescription. To evaluate pharmaco-epidemiology of drugs utilised for cataract surgery, a retrospective study was conducted in the department of pharmacology, RG Kar Medical College, Kolkata. Data from bed head tickets of one year, available in medical record section, were collected in case report forms and analysed. Utilisation pattern of drugs like dosage form, dose, route and frequency of administration and duration of therapy were audited. Drug prescription versus therapeutic indication was also evaluated. Price of the prescribed drugs was evaluated for rationality towards cost-effective prescription. For 848 cases of cataract surgery, drugs were prescribed pre-, per- and post-operatively. Different fluoroquinolone antibiotics, anti-inflammatory and mydriatic-cycloplegic agents were prescribed. High or low cost drugs were prescribed both in generic (52%) and brand (48%) names. Few Latin abbreviations were used in directions. Different parameters and study results were discussed from various aspects to explore their social impacts. Though prescription pattern was almost rational, some parts need improvement. Healthcare provider should be aware of cost-effectiveness of the prescribed drugs for the benefit of patients to provide a rational prescription.
