In the era of managed care, quality of medical care standards continue to materialize. Most of these standards have long, cumbersome, and complex rules. In light of such problematic rules, efficient ways of retrieving information for a computerized score card are needed. A technique for making such rules less difficult to use is to create Boolean expressions for each quality of care indicator. These Boolean expressions partition the indicators into key words and phrases so that information can be retrieved readily from a system. This study incorporates an outpatient clinical information system of a major university hospital. The technique used to retrieve information and related issues are discussed in the following text.
