title: The ASCO Oncology Composite Provider Utilization File: New Data, New Insights.
abstract: As we seek to understand the changing practice environment in oncology, the need for accurate information about demand for services, distribution of the delivery system in this sector of the health economy, and other practice trends is apparent. In this article, we present analysis of the sector using one of the public use files from the Centers for Medicare & Medicaid Services in combination with other publicly available data. Medicare data are particularly useful for this analysis because cancer is associated with aging and Medicare is the primary payer in the United States for patients older than age 65. As a result, nearly all oncologists who serve adult populations are represented in these data. By combining publicly available datasets into what we call the ASCO Provider Utilization File,we can investigate a wide range of supply, demand, and practice issues. We calculate the average work performed per physician, observe regional differences in work production,and quantify the downside risk and upside potential associated with the provision of chemotherapy drugs. Comparing the supply of oncologists by state with physician work relative value units and with estimates of cancer incidence by state reveals intriguing differences in the distribution of physicians and the demand for oncology services. In addition, our analysis demonstrates significant downside practice risk associated with the provision of drug therapy to Medicare beneficiaries. The economic risk associated with the purchase and delivery of chemotherapy is of particular concern as pressure for value increases. This article provides a description of a new dataset and interesting observations from these data.
