Co-occurring mental illness and health care utilization and expenditures in adults with obesity and chronic physical illness.

The objectives of the study were to compare health care expenditures between adults with and without mental illness among individuals with obesity and chronic physical illness. We performed a cross-sectional analysis of 2440 adults (older than age 21) with obesity using a nationally representative survey of households, the Medical Expenditure Panel Survey. Chronic physical illness consisted of self-reported asthma, diabetes, heart disease, hypertension, or osteoarthritis. Mental illness included affective disorders; anxiety, somatoform, dissociative, personality disorders; and schizophrenia. Utilization and expenditures by type of service (total, inpatient, outpatient, emergency room, pharmacy, and other) were the dependent variables. Chi-square tests, logistic regression on likelihood of use, and ordinary least squares regression on logged expenditures among users were performed. All regressions controlled for gender, race/ethnicity, age, martial status, region, education, employment, poverty status, health insurance, smoking, and exercise. All analyses accounted for the complex design of the survey. We found that 25% of adults with obesity and physical illness had a mental illness. The average total expenditures for obese adults with physical illness and mental illness were

1756, respectively. After controlling for all independent variables, among adults with obesity and physical illness, those with mental illness were more likely to use emergency services and had higher total, outpatient, and pharmaceutical expenditures than those without mental illness. Among individuals with obesity and chronic physical illness, expenditures increased when mental illness is added. Our study findings suggest cost-savings efforts should examine the reasons for high utilization and expenditures for those with obesity, chronic physical illness, and mental illness.

Depression Treatment Patterns among Elderly with Cancer.

OBJECTIVES To compare the rates of major and minor depression in cohorts of women veterans with diabetes or heart disease or hypertension and examine variations in these rates by demographic, socioeconomic, and health status among these women. METHODS This was a retrospective cross-sectional analysis of fiscal year 2002 and 2003 data on 13,430 women veterans with diabetes or heart disease or hypertension who were diagnosed with depression and used Veteran Health Administration (VHA) clinics. International Classification of Diseases, 9th ed. Clinical Modification codes from merged VHA and Medicare claims files were used to identify diabetes, heart disease, hypertension, and depression. Chi-square tests and multinomial logistic regressions were used to characterize women veterans with major and minor depression. RESULTS Of all the women veterans diagnosed with diabetes or heart disease or hypertension and using the VHA clinics, 27% were diagnosed with depression. Of these 13,430 women with any depression, 60% were diagnosed with minor depression and 40% had major depressive disorders (MDD). Compared to major depression, minor depression was significantly more likely among women veterans who were older, without any other psychiatric condition and substance use disorders. CONCLUSIONS Minor depression is highly prevalent among women veterans with complex chronic illness, such as diabetes or heart disease or hypertension (i.e., women at risk or with cardiovascular conditions), suggesting a need to closely monitor these women to reduce the risk of major depression. Some subgroups of women were more likely to have minor depression than major depression; studies that exclusively focus on major depression will selectively miss these subgroups of women veterans.

Depression treatment patterns among women veterans with cardiovascular conditions or diabetes

Objective To estimate excess health care expenditures associated with gastroesophageal reflux disease (GERD) among elderly individuals with chronic obstructive pulmonary disease (COPD) and examine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors to the excess expenditures, using the Blinder–Oaxaca linear decomposition technique. Methods This study utilized a cross-sectional, retrospective study design, using data from multiple years (2006–2009) of the Medicare Current Beneficiary Survey linked with fee-for-service Medicare claims. Presence of COPD and GERD was identified using diagnoses codes. Health care expenditures consisted of inpatient, outpatient, prescription drugs, dental, medical provider, and other services. For the analysis, t-tests were used to examine unadjusted subgroup differences in average health care expenditures by the presence of GERD. Ordinary least squares regressions on log-transformed health care expenditures were conducted to estimate the excess health care expenditures associated with GERD. The Blinder–Oaxaca linear decomposition technique was used to determine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors, to excess health care expenditures associated with GERD. Results Among elderly Medicare beneficiaries with COPD, 29.3% had co-occurring GERD. Elderly Medicare beneficiaries with COPD/GERD had 1.5 times higher (

Ordinary least squares regression revealed that individuals with COPD/GERD had 36.3% (P<0.001) higher expenditures than did those with COPD/no GERD. Overall, 30.9% to 43.6% of the differences in average health care expenditures were explained by differences in predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors between the two groups. Need factors explained up to 41% of the differences in average health care expenditures between the two groups. Conclusion Among elderly Medicare beneficiaries with COPD, the presence of GERD was associated with higher expenditures. Need factors primarily contributed to the differences in average health care expenditures, suggesting that the comanagement of chronic conditions may reduce excess health care expenditures associated with GERD.

Type of Multimorbidity and Patient-Doctor Communication and Trust among Elderly Medicare Beneficiaries

The authors of this study examined the association between health-related quality of life and financial barriers to care, defined as not getting the needed care due to cost considerations. To better understand health-related quality of life among women veterans, the authors compared women veterans to women non-veterans. The authors conducted cross-sectional analyses using data from the 2009 Behavioral Risk Factor Surveillance System survey. The authors assessed four health-related quality of life measures: (1) general health; (2) physical health; (3) mental health; and (4) functional status. The authors performed multinomial logistic regressions to examine the relationship between financial barriers to receiving healthcare and health-related quality of life measures after controlling for other independent variables. The authors included women veterans not in active military duty (N = 3,747) and a matched sample of women non-veterans (N = 3,747), selected using a propensity score method so that they would have distributions of demographic and socioeconomic characteristics similar to those of the veterans. Overall, 14% of women reported financial barriers. Women who reported financial barriers to receiving healthcare were more likely to have poor health-related quality of life in all four dimensions than those who did not report such barriers. Compared to women non-veterans, women veterans did not differ in reported financial barriers but were more likely to report poor health-related quality of life. Reporting financial barriers to receiving needed healthcare was significantly associated with poor health-related quality of life among women. Veteran status was also significantly associated with poor health-related quality of life. These findings suggest the need for healthcare policy makers and practitioners to align emerging new models of healthcare delivery to improve health-related quality of life for women veterans.
