  1. Border crossing for hospital care and its implications for the use of statewide data.

    Article - En anglais

    A major concern of researchers using state data sets for population-based analyses and market share studies in the health care sector is the potential bias caused by « border crossing »-patients receiving care out of state.

    By using the Health Care Financing Administration (HCFA) discharge abstract files for 1987 and 1988, we found that « border crossing » is not a serious problem for the two large states we examined.

    Only 4.4% of New York patients and 2.15% of California patients received care out of state.

    At the county and zip code level, « border crossing » is more frequent but tends to be concentrated in areas adjacent to other states.

    Even excluding all zips with more than 10% of patients crossing the « border » results in a small loss of patients (2.2% for New York and 1.0% for California).
