Health status of Medicare enrollees in HMOs and fee-for-service in 1994.

We compared the health status of 863 health maintenance organization (HMO) enrollees with that of 4,576 non-enrollees, controlling for demographics and area of residence, using 1994 data from the Medicare Current Beneficiary Survey (MCBS). HMO respondents were less likely to report fair or poor health, functional impairment, or heart disease. Average predicted costs based on various health-status measures were substantially lower for HMO respondents than for respondents in fee-for-service (FFS) arrangements. The Medicare payment formula for HMOs does not adequately adjust for the better health and consequent lower expected costs of HMO enrollees. The addition of health-status measures would improvement payment accuracy and reduce average HMO payments significantly below current levels.

Government subsidy of critical-need occupations: the case of nurses.

This paper undertakes an econometric evaluation of governmental policies aimed at increasing the labor force supply of nurses and at effecting greater hospital substitution among auxilliary health personnel, in times of nurse shortage. The methodology is to employ a simultaneous equation, multi-nurse econometric model which is estimated by a three-stage least-squares procedure incorporating use of logit transformation to deal with limited dependent variables and use of weighted least squares to deal with heteroskedasticity.

Satisfaction with care: do Medicare HMOs make a difference?

Differences in satisfaction with care and perceptions of doctor/patient interactions were compared for Medicare beneficiaries enrolled in health maintenance organizations (HMOs) and beneficiaries in the fee-for-service (FFS) sector (nonenrollees). After controlling for covariates, beneficiaries expressed satisfaction with their care, regardless of where they received it. However, HMO enrollees were more likely than nonenrollees were to be very satisfied with the costs of care and with getting care at one location. In contrast, for every components-of-care measure, nonenrollees were more likely than HMO enrollees were to indicate high satisfaction with the quality of interaction with their physicians.
