In this U.S. Medicare managed care population, COPD posed a substantial burden in terms of both respiratory-related and total healthcare costs. A comparison of these cost-of-illness estimates to those for elderly COPD patients in other countries would be of great interest, given the increasing age of populations in most Western countries.

Current smokers incurred the highest productivity losses, which translated into higher costs to employers for current smokers. Costs were lower for former smokers and nonsmokers.

Using data from the Medicare Current Beneficiary Survey, we identify differences in hospital days, home health visits and physician office visits across five geographical categories. After controlling for individual characteristics and availability of health care providers, we find significant differences in service use. Results show greater use of home health care and less use of physician office visits and hospital care in rural areas. Because service use exhibits patterns of substitution and complementarity, future research on the use of health services needs to move beyond modeling the use of single services to modeling the range of services used.

Current standards of health care support the view that diabetes can be managed in an outpatient setting, thereby preventing costly hospitalization. Yet, recent studies on access to care suggest that rural residents do not receive the same services for diabetes care as their urban counterparts. This study identifies differences in use for three types of services-hospital care, home health visits, and physician office visits--by geographical location. Using a sample of 6,698 Medicare beneficiaries, the authors performed multivariate analysis of variance to test the influence of geographical differences on each type of service use after controlling for the other types of service use and individual factors. Results showed significant differences among the geographical categories, with diabetic individuals in the most sparsely populated communities reporting fewer physician office visits and more home health visits than their urban counterparts. Because this pattern may have a negative impact on health outcomes, additional research is needed to determine the optimal array of services necessary to manage chronic diseases, such as diabetes, in rural areas.

Between 1989 and 1997, the Food and Drug Administration approved four new-generation antipsychotic medications for use in the treatment of schizophrenia. This article examines factors associated with the use of new antipsychotic medications as compared with traditional antipsychotic medications from patient interviews, medical records, and a physician survey administered at schizophrenia treatment sites around the country as part of the Schizophrenia Care and Assessment Program. The following variables were significantly associated with a higher probability of receiving an atypical antipsychotic medication in multiple regression analysis at p < .05: female, younger age, younger age of onset, non-African American, having a higher Positive and Negative Syndrome Scale-Negative Syndrome subscale score. Some physician characteristics were statistically significant in the bivariate results but not in the multivariate analyses. Access to new atypical antipsychotic medications is dependent on more than clinical characteristics. In particular, barriers to access may exist for African Americans. Physician access to information about advances in drug therapies also may play a substantial role in the rate of diffusion of new medications.

Results document rates of antipsychotic adherence and predictors of nonadherence and hospitalization. Findings may be useful to health plan administrators, formulary decision makers, and physicians.

This study in veterans shows that the presence of mental illness and its comorbidities represents a significant risk factor for the diagnosis of liver disease, including HCV and alcohol-related cirrhosis.
