Ambulatory care classification systems.

This article describes several methods of classifying resources used in ambulatory care into isoresource consumption groups. These methods are based on resources used by patients during a year, rather than on resources used in a single visit. Variables used to partition patient-year charges into isoresource consumption groups are age, race, number of health problems or major diagnostic categories addressed, number of medications or categories of medications prescribed, and indexes developed to reflect resources used by diagnostic categories during a patient-year. Confirmation in other settings of the findings of this study would have important implications for the design of prospective payment plans for ambulatory care.

Classification of ambulatory care using patient-based, time-oriented indexes.

This paper presents a new approach to the classification of ambulatory care into isoresource consumption groups. In contrast to classification schemes based on visits, this case-mix approach creates an index based on resources used by diagnostic categories by a patient during a year. An application of this method to a primary care, group practice data base produced resource consumption groups with coefficients of variation in an acceptable range compared with the coefficients of variation of the diagnosis-related groups used to classify inpatient care.

A problem-oriented approach to medical information systems: an application in a primary care group practice.

A relatively simple computer-based information system developed for a primary care group practice at the San Francisco Veterans Administration Hospital contributes to the management of the practice, to improvement of medical care for patients within the group, and to research studies on resource utilization in the management of chronic diseases and the evaluation of care of chronically ill patients. Preliminary results from the use of the information system are encouraging and demonstrate that much may be achieved by information systems that do not attempt to computerize the entire medical record.
