title: Risk factor information found in medical records of lung and prostate cancer cases, New Mexico Tumor Registry (United States).
abstract: The conduct of public health surveillance and epidemiologic investigations would be enhanced by a cost-effective method for the collection of population-based cancer risk-factor data. We assessed the feasibility of ascertaining such data from hospital medical records during routine abstraction of information from a cancer registry. We examined the medical records of a representative sample of prostate and lung cancer cases diagnosed during 1992 and 1993 from the New Mexico (United States) Tumor Registry (NMTR) database. Registry personnel abstracted ancillary information from the medical records of 575 prostate and 273 lung cancer cases. Of medical records from 848 cases, 90 percent documented a history of tobacco use, 77 percent contained any family medical history, and 48 percent documented occupational information sufficient to allow coding into standard occupational groups. Availability of occupation and industry varied by patient ethnicity, age at diagnosis, marital status, and type of hospital, indicating the potential for bias in studies using occupational information from medical records. Our findings suggest that risk factor information abstracted from medical records may provide valuable information for public health surveillance, but is generally too incomplete to serve as a single source of exposure information for etiologic studies. Family histories in medical records may be sufficient for population-based ascertainment of affected relative pairs for genetic epidemiology studies for some cancer types.
