Medical audit overseas the observance of standards of medical treatment of all levels of health care delivery system. Prescription surveys are a component of the medical audit which provide a relatively unbiased picture of prescribing habits and also identifies aberrant or suboptimal prescribing. Few such surveys have been undertaken mostly at tertiary care hospitals on sample sizes of 200-250 prescriptions. But this survey encompasses screening of over a hundred thousand OPD prescriptions of secondary level government hospital. With such a huge sample size it has been possible to investigate disease morbidity, drug utilization, core prescribing indicators in pediatric, adult and geriatric patients collectively, and also study the trends in prescribing.
