The purpose of this study is to find out if there has been any change in the outpatient visit to tertiary care hospitals after the introduction of the new healthcare program that divides the roles of doctors and pharmacists and the reason for the change if there is any. Two tertiary care hospitals with the largest capacity of 1200 beds and two tertiary care hospitals with the lowest capacity of 600-700 beds were randomly selected. Data of the outpatient visits from March-May 2(xx), before the new healthcare system was adopted, were compared with the data from March-May 2001, after the new policy was adopted. Outpatient visits have decreased 5.8% after the new system. There has been a dramatic decrease, especially, in the department of OB-GYN and Pediatrics of tertiary hospitals. Decrease in re-visits is much higher than the first visits. Female patients decreased more than the male patients. Outpatient visits by economically active patients group aged 25-44 declined much. Tertiary hospitals in Seoul and Kyonggi Province, as well. Outpatient income of tertiary hospitals has dropped up to 14.7% due to the decline in outpatient visits and pharmaceutical income, and resell price system which in turn has caused the hospital financial deficits. While the new program has succeeded in lowering the use of antibiotics and injections, it has the pitfall of prescribing long days and expensive drugs. A full-fledged review of the system should be conducted for the establishment of the new system and I believe this study may be a useful references. Furthermore, more profound and overall studies on the chance in the patients use of hospitals are needed.
