NAME OF STUDY:   Cost of Care for Severely Mentally Ill HMO Members
PROJECT DIRECTOR/PI:   Bentson McFarland (Kaiser Foundation Hospital, OR)
PROJECT DATES:   September 1990 - April 1996
RESEARCH QUESTIONS/GOALS:   What is the use and cost of HMO services and public mental health services by persons with severe mental illness, and how does it influence their duration of enrollment in the HMO? Is this population appropriately served by “mainstream” HMOs as compared to more specialized HMOs?
BRIEF DESCRIPTION OF METHODS AND DATA:   The research focused on 250 persons with schizophrenia or bipolar disorder enrolled in the Northwest Region of Kaiser Permanente, which serves 25 percent of the population of metropolitan Portland, Oregon. The control group consisted of 500 age- and sex-matched HMO enrollees; survival analysis was used to compare enrollment duration between subjects and controls, and proportional hazards models were used to measure how cost and use of public mental health services influence length of care in HMOs.
AVAILABILITY OF RESULTS:   The results were presented at the annual APHA convention last November, and abstracts will be submitted to the Archives of General Psychiatry.
