Evaluation of Drug Utilization Patterns during Initial Treatment in the Emergency Room : A Retroprospective Pharmacoepidemiological Study

الملخص EN

Background.

We assessed the prescribing trends, average number of drugs per prescription, and cost per prescription during the initial contact of the patient with the physician in emergency room.

Methods.

This retro-prospective study was conducted over a period of six months.

Medical records of two hundred patients were reviewed for prescribing patterns.

Results.

52 different types of drugs (996 drugs) were prescribed in total 200 prescriptions during the mean time spent in emergency room of 2.8 ± 1.4 hours.

The average number of drugs per prescription was 4.2 ± 1.2.

95% of drugs were prescribed by trade name.

Average drugs cost per prescription was 784 ± 134 rupees (17USD).

Conclusion.

Polypharmacy remains the main form of irrational prescribing.

Prescribing patterns of drugs were knowledge based rather than WHO criteria for rational use of drugs.
