Care of patients with colorectal cancer. A comparison of a health maintenance organization and fee-for-service practices.

The presence of a population-based cancer registry in a community with a health maintenance organization (HMO) enabled a detailed, longitudinal comparison to be made of care given for colorectal cancer in an HMO with traditional fee-for-services (FFS) care. An interview survey of 39 HMO and 150 FFS patients was supplemented with data from the cancer registry. Patients seen by the two provider groups were similar with respect to sociodemographic characteristics, severity of disease at diagnosis, and concurrent medical conditions. The HMO patients received more prediagnostic care but did not receive definitive surgical treatment as quickly as the FFS group. There were few differences in care, however, once diagnosis was made; there were no differences in access to care, rates of definitive surgery, chemotherapy, radiation therapy, length of hospitalization, number of follow-up physician visits, and most measures of satisfaction with care. No differences in outcome, including 4-year survival and 1-year health status, were found. HMO patients expressed significantly less concern about the cost of their care. These findings suggest an initial hesitancy to provide definitive care by the HMO but no significant differences in either the process or outcome of care once definitive care is begun.
