Impact of HMO ownership on management processes and utilization outcomes.

OBJECTIVE: To examine the effects of health maintenance organization (HMO) ownership characteristics on selected utilization outcomes and management processes affecting utilization. STUDY DESIGN: We used 1995 HMO data from the American Association of Health Plans. PATIENTS AND METHODS: Using regression analysis, we examined the relation between HMO utilization (hospital discharges, days, and average length of stay; cardiac catheterization procedures; and average cost of outpatient prescriptions) and the structural characteristics of HMOs: ownership type (insurance company, hospital, physician, independent, and national managed care company), HMO size, for-profit status, model type, geographic region, and payer mix. RESULTS: HMO ownership type is significantly associated with medical management processes, including risk sharing by providers, risk sharing by consumers, and other management strategies. Relative to hospital-owned HMOs, insurance company-owned HMOs have fewer hospital discharges, fewer hospital days, and longer lengths of stay. National managed care organization-owned HMOs have fewer cardiac catheterizations and lower average outpatient prescription costs. Independently owned HMOs have more cardiac catheterizations. For-profit HMOs have lower prescription costs. Relative to hospital-owned HMOs, insurance company-owned HMOs are more likely to use hospital risk sharing and provider capitation and less likely to use out-of-pocket payments for hospital use and a closed formulary. National managed care organization-owned HMOs are less likely to use provider capitation, out-of-pocket payments for hospital use, catastrophic case management, and hospital risk sharing. Physician-hospital-owned HMOs are less likely to use catastrophic case management. For-profit HMOs are more likely to use hospital risk sharing and catastrophic case management. CONCLUSION: HMO ownership type affects utilization outcomes and management strategies.

Public insurance substituting for private insurance: new evidence regarding public hospitals, uncompensated care funds, and Medicaid.

This paper examines the impact of public health insurance programs, whether structured as subsidies to health care providers (public hospitals and uncompensated care reimbursement funds) or as direct insurance (Medicaid), on the purchase of private health insurance. The presence of a public hospital is associated with a lower likelihood of private insurance for those with incomes between 100-200% and 200-400% of the poverty level. Uncompensated care reimbursement funds were associated with less purchase of private health insurance and a higher likelihood of being uninsured across all income groups. More generous Medicaid programs showed both safety-net and crowd out effects.

Detection and documentation of DRG-relevant comorbidities using laboratory tests.

Germany will soon begin per case payment by DRG, and preparations are in progress in most hospitals and insurance companies. The Academic Teaching Hospital Munich-Schwabing in Munich decided to explore coding strategies by considering the impact of diagnoses that could be detected by pathology tests. An Australian database was analysed. We detected "discriminating" diagnoses--that is, diagnoses that could be found in level A or B DRGs, and not in the respective lower severity DRG. After isolating 584 diagnoses, they were rated by a laboratory specialist, to determine whether they could be proved by pathology tests. 187 diagnoses were selected in this way. In the next step, theoretical cases were generated and grouped. 157 diagnoses were found to produce a switch to a higher DRG. The diagnoses, the DRGs and the respective laboratory tests were then arranged in a small MS-Excel program to allow comfortable browsing. The overall success rate of 84% shows that laboratory medicine can contribute to correct coding for DRGs.

Introducing health insurance in Vietnam.

Like many other countries Vietnam is trying to reform its health care system through the introduction of social insurance. The small size of the formal sector means that the scope for compulsory payroll insurance is limited and provinces are beginning to experiment with ways of encouraging people to buy voluntary insurance. Methods of contracting between hospitals and insurance centres are being devised. These vary in complexity and there is a danger that those based on fee for service will encourage excessive treatment for those insured. It is important that the national and provincial government continue to maintain firm control over funding while also ensuring that a substantial and targeted general budget subsidy is provided for those unable to make contributions.
