Health care reform in Oregon: the impact of the Oregon Health Plan on utilization of mammography
2000
Abstract Background: In 1994, Oregon implemented the Oregon Health Plan (OHP), extending health care coverage under a system of capitated managed care to uninsured citizens living below the Federal Poverty Level (FPL). We conducted a study to measure receipt of clinical preventive services among women newly enrolled in the OHP. Methods: Six hundred and sixty six women aged 52–64, and living below the FPL in Oregon were randomly selected from OHP enrollment rosters and interviewed by telephone. A follow-up survey was conducted 1 year later. The main outcome of interest was receipt of a screening mammogram during the first year in the OHP. Results: At enrollment 17% (65/383) of participants had never had health care coverage. Sixty-six percent of the women (220/333) were overdue for a mammogram. Fifty-five percent (121/220) reported cost as the main reason they had not had this procedure. Mammography rates doubled under the OHP (21% to 52%, 95% CI = 0.25–0.38, p p = 0.04), citing cost as the main reason for being overdue (OR3.0, 95% CI = 1.3-7.2, p = 0.014), receipt of a routine checkup (OR9.5, 95%CI = 3.7–24.9, p p Conclusion: The OHP enrolled and successfully delivered clinical preventive services to a medically under served population. Even after removing the financial barrier, obstacles to mammography remain. These may be overcome by health systems changes to insure receipt of routine checkups and appropriate provider recommendations.
