Outpatient services are medical procedures or tests that can be done in a medical center without an overnight stay. Many procedures and test can be done in a few hours. The last procedure of an outpatient service is mostly to acquire drugs from pharmacy room. In this paper, a veterans general hospital with three buildings around 16.8 hectare in south Taiwan is studied.

Shortage of drugs is normally disallowed in a hospital. Under current drug inventory control policy of this hospital, sometimes there are still shortages of some drugs. To overcome this problem, usually, the staff of dispensing division will increase safety stocks of such shortage drugs. Therefore, total inventory level of drugs stays high in this hospital.

In this study, data mining technology is applied to detect possible issues that caused drug shortage. Around 476,000 of data extracted from National Health Insurance files range from January to March, 2010, the unit is monthly and in the multi-level concepts, MIS = 0.001%, MIC = 50%, the results came out with 19 association rules.
