Effect of a computerized ambulatory medical record system on the validity of claims data.

Relationships were compared between claims data and charts data in a medical practice when a paper chart and manually prepared claims forms were used and after implementation of a computerized medical record system (COSTAR) in which claims data were derived automatically from the medical database. Claims data and chart data resembled each other more closely when the computer system was used, suggesting that claims data derived in this manner may have particular value in health care planning and research.

A comparison of medical record with billing diagnostic information associated with ambulatory medical care.

The degree of similarity between diagnostic information furnished with claims and that simultaneously entered into the medical record was estimated for 1,215 private office visits in British Columbia, Canada. For each visit, claim card and chart diagnoses were compared by having three independent internists (blinded to source and type of the data) make judgments about each diagnostic pair. The judges were highly consistent internally and their judgments were stable over time. In 40 per cent of cases chart and claims data were judged dissimilar, and in 38 per cent of cases claims data were judged more valuable as a reflection of the primary problem treated. The degree of judged similarity of chart and claims data correlated significantly and negatively with physician workload, income, and judges' preference for the billing card diagnosis. We conclude that in using claims data to determine the content of ambulatory visits, independent validation of such data may be important.

A computerized prenatal record.

An entirely computerized ambulatory medical record system is operational in a large health maintenance organization. A unique subsystem was designed for use in prenatal care, in which the provider's completion of a single encounter form at the time of visit meets all the information requirements of care delivery, administration, and quality assurance. Instead of using a conventional paper chart, computer-generated summaries and flow charts are automatically provided for scheduled visits and for use as a hospital preadmission record, significantly reducing the provider effort expended on record keeping. On-line inquiry function is also available using terminals at the ambulatory center and the hospital. The computer data base has been used for quality assurance studies in prenatal care. The system is well accepted by providers, is reliable, and is cost effective.
