Physicians, carefully adhering to the definitions of Physicians' Current Procedural Terminology (CPT) billing codes, used the same CPT codes to denote evaluation and management services that varied widely in work and used different codes for services whose work was the same. As payment shifted to the Medicare Fee Schedule, it was important that the coding system be redefined so that codes consistently reflect the resource costs of these services. Redefining these codes for a resource-based payment system required an understanding of how verifiable predictors relate to physician work. ⋯ Intraservice time, which accounted for 90% of the variance, was the most important predictor of intraservice work. Specification of time, which previously had not been an element in the definitions of CPT codes for evaluation and management services, was useful in refining these codes so that their value corresponds more closely to resource costs. Other predictors of work were site of service or visit type, patient status (new/initial, established/subsequent), and referral status (consultation, nonconsultation).

This study compared the ability of a clinical and administrative data base in New York State to predict in-hospital mortality and to assess hospital performance for coronary artery bypass graft surgery. The results indicated that the clinical data base, the Cardiac Surgery Reporting System, is substantially better at predicting case-specific mortality than the administrative data base, the Statewide Planning and Research Cooperative System. ⋯ The addition of new risk factors from the Statewide Planning and Research Cooperative System improved the predictive power of both systems but did not diminish the difference in effectiveness of the two systems. The three unique clinical risk factors in the Cardiac Surgery Reporting System (ejection fraction, reoperation, and more than 90% narrowing of the left main trunk) seemed to account for much of the difference in effectiveness of the two systems.

The number of hospital closures increased substantially after the implementation of Medicare's Prospective Payment System (PPS). This acceleration in closures raised a number of concerns over current payment policies and their impact on access. This paper investigates hospital closures that occurred in 1985 through 1988. ⋯ The share of Medicare patients also affected closure indirectly, through its effects on profit. Competition appears to affect the odds of closure through its effects on the number of cases. In addition, hospitals in areas with small or declining population are more at risk than other hospitals in both urban and rural areas.

To determine which characteristics of hospitals may be related to a higher quality of care, the association of hospital characteristics with the outcomes of medical record review by state Peer Review Organizations (PROs) was studied. The two data sources were: 1) the AHA 1986 Annual Survey of Hospitals and 2) reviews completed between July 1987 through June 1988 from six large PROs. For each hospital the percentage of cases that failed physician review (the confirmed problem rate) was computed. ⋯ All characteristics significantly related to higher confirmed problem rates were also related to higher adjusted mortality rates in a previous study of 3,100 U. S. hospitals. The results suggest that hospital resources, including financial status, training of medical personnel, and availability of sophisticated equipment, are related to the quality of care provided by the hospital.
