This study assessed the effect of hospital competition and HMO penetration on mortality after hospitalization for six medical conditions in California, New York, and Wisconsin. We used linked hospital-discharge and vital-statistics data to study adults hospitalized for myocardial infarction, hip fracture, stroke, gastrointestinal hemorrhage, congestive heart failure, or diabetes. We estimated logistic regression models with death within 30 days of admission as the dependent variable and hospital competition, HMO penetration, and hospital and patient characteristics as explanatory variables. Higher hospital competition was associated with lower mortality in California and New York but not Wisconsin. Higher HMO penetration was associated with lower mortality in California but higher mortality in New York. These findings suggest that hospitals in highly competitive markets compete on quality even in the absence of mature managed-care markets. The findings also underscore the need to consider geographic effects in studies of market structure and hospital quality.

Over the past 15 years, striking new settlement patterns have emerged that have brought about unprecedented geographic dispersion in the population of approximately 45 million Hispanics in the United States. In this study, the authors compare the health care experiences of working age U.S.-born Mexican Americans and Mexican immigrants living in new and traditional Hispanic destinations. They use a geocoded version of the Medical Expenditure Panel Survey Household Component linked to contextual data from secondary sources. They characterize destinations as new or traditional using information on the percentage of the population that was Hispanic in 1990 and the growth in percent Hispanic between 1990 and 2000. The authors find that, compared with living in destinations with a well-established Hispanic presence, U.S.-born Mexican Americans living in new destinations have less favorable health care outcomes, including a greater probability of having an unmet need for or delay in receiving medical care and reduced satisfaction with care.

Inadequate access and poor quality care for immigrants could have serious consequences for their health and that of the overall U.S. population. The authors conducted a systematic search for post-1996, population-based studies of immigrants and health care. Of the 1,559 articles identified, 67 met study criteria of which 77% examined access, 27% quality, and 6% cost. Noncitizens and their children were less likely to have health insurance and a regular source of care and had lower use than the U.S. born. The foreign born or non-English speakers were less satisfied and reported lower ratings and more discrimination. Immigrants incurred lower costs than the U.S. born, except emergency department expenditures for immigrant children. Policy solutions are needed to improve health care for immigrants and their children. Research is needed to elucidate immigrants' nonfinancial barriers, receipt of specific processes of care, cost of care, and health care experiences in nontraditional U.S. destinations.

This study compares expenditures for physician services in a closed panel gatekeeper health maintenance organization (HMO) and an open panel point of service HMO that share the same physician network. The study uses administrative files of the two study HMOs for 1994-1995 to assess differences in spending for primary care physicians' (PCPs') services, specialists' services, and total physician services. When the copayments for PCP visits and PCP-referred specialist visits were $0, total physician expenditures were 4 percent higher in the gatekeeper HMO than in the point of service plan (p < .05). When the copayments for PCP visits and PCP-referred specialist visits were $10, total physician expenditures ranged from equal in both HMOs to 7 percent higher in the gatekeeper HMO (p < .01), depending on the copayment for self-referred visits. Expenditures for specialists'services were not higher in the point of service plan. The authors conclude that direct patient access to specialists does not necessarily result in higher physician or specialist expenditures in HMOs.

This study uses hospital discharge data for 1992-1994 to assess differences between HMO and insured non-HMO patients in California and Florida with regard to the quality of the hospitals used for coronary artery bypass graft (CABG) surgery. The authors found that commercially insured HMO patients in California used higher quality hospitals than commercially insured non-HMO patients, controlling for patient distance to the hospital. In contrast, commercially insured HMO and non-HMO patients in Florida were similarly distributed across hospitals of different quality levels, whereas Medicare HMO patients in Florida used lower quality hospitals than patients in the standard Medicare program. The authors conclude that the association between HMO coverage and hospital quality may differ across geographic areas and patient populations, possibly related to the maturity and structure of managed care markets.
