Managed Care Research
Dr. Friedman has considerable interest and experience in managed care research relating to elderly people. In the early 1990s, he conducted a survey of the medical directors of the Medicare health maintenance organizations to determine the extent to which those organizations were carrying out recommended geriatric practices (Friedman, B, and Kane, RL. HMO Medical Directors' Perceptions of Geriatric Practice in Medicare HMOs. Journal of the American Geriatrics Society, 41(10): 1144- 49, October 1993). Since the mid 1990s he has been studying differences in hospital, skilled nursing facility, and home healthcare utilization in two managed care organizations: a Social Health Maintenance Organization (HMO) and a Medicare risk HMO. Here he has been applying various sophisticated analytic techniques, including bivariate probit, instrumental variables, sample selection models, and the two-part model.
Health services research focusing on organization, financing, and delivery of care for the elderly; development of risk-adjusted payment models, and outcomes research.
