The Impact of Mental Health Conditions on Public Insurance Costs of Treating HIV/AIDS.

Medicare and Medicaid insurance claims data for Californians living with HIV are analyzed in order to determine: (1)The prevalence of treatment for particular mental health diagnoses among people living with HIV (PLWH) with Medicare or Medicaid insurance in 2010; (2)The relationship between individual mental health conditions and total medical care expenditures; (3)The impact of individual mental health diagnoses on the cost of treating non-mental health conditions; and (4)The implications of the cost of mental health diagnoses for setting managed care capitation payments. We find that the prevalence of mental health conditions among PLWH is high (23% among Medicare and 28% among Medicaid enrollees). PLWH with mental health conditions have significantly higher treatment costs for both mental health and non-mental health conditions. Setting managed care capitations that account for these greater expenditures is necessary to preserve access to both mental health and physical health services for PLWH and mental health conditions.

Trauma, Family Factors and the Mental Health of Homeless Adolescents.

Family factors, such as poor family functioning and trauma, have been associated with negative outcomes for homeless adolescents. Further study is needed to better understand how family factors and trauma jointly relate to mental health problems and externalizing behaviors among homeless adolescents. Structural equation modeling was used to examine the influence of trauma (encompassing traumatic events experienced prior to, and after, becoming homeless) and family factors (poor family functioning and family conflict) on mental health problems and externalizing behaviors (substance use, delinquent behaviors, and sexual risk) among 201 homeless adolescents, ages 12 to 17 years. Trauma, poor family functioning, and family conflict significantly predicted greater mental health problems, delinquent behaviors, high-risk sexual behaviors and substance use. Overall, the findings suggest that family factors appear to be key to understanding mental health problems and externalizing behaviors among homeless adolescents. Implications, limitations and future directions are addressed.

Association between Federally Qualified Health Center usage and emergency department utilization among California's HIV-infected Medicaid beneficiaries, 2009.

Federally Qualified Health Centers (FQHCs) have long been important sources of care for publicly insured people living with HIV. FQHC users have historically used emergency departments (EDs) at a higher-than-average rate. This paper examines whether this greater use relates to access difficulties in FQHCs or to characteristics of FQHC users. Zero-inflated Poisson models were used to estimate how FQHC use related to the odds of being an ED user and annual number of ED visits, using claims data on 6,284 HIV-infected California Medicaid beneficiaries in 2008-2009. FQHC users averaged significantly greater numbers of annual ED visits than non-FQHC users and those with no outpatient usage (1.89, 1.59, and 1.70, respectively; P = 0.043). FQHC users had higher odds of being ED users (OR = 1.14; 95%CI 1.02-1.27). In multivariable analyses, FQHC clients had higher odds of ED usage controlling for demographic and service characteristics (OR = 1.15; 95%CI 1.02-1.30) but not when medical characteristics were included (OR = 1.08; 95%CI 0.95-1.24). Among ED users, FQHC use was not significantly associated with the number of ED visits in our models (rate ratio (RR) = 1.00; 95%CI 0.87-1.15). The overall difference in mean annual ED visits observed between FQHC and non-FQHC groups was reduced to insignificance (1.75; 95% CI 1.59-1.92 vs 1.70; 95%CI 1.54-1.85) after adjusting for demographic, service, and medical characteristics. Overall, FQHC users had higher ED utilization than non-FQHC users, but the disparity was largely driven by differences in underlying medical characteristics.

Do Medicare Beneficiaries Living With HIV/AIDS Choose Prescription Drug Plans That Minimize Their Total Spending?

This article examines whether California Medicare beneficiaries with HIV/AIDS choose Part D prescription drug plans that minimize their expenses. Among beneficiaries without low-income supplementation, we estimate the excess cost, and the insurance policy and beneficiary characteristics responsible, when the lowest cost plan is not chosen. We use a cost calculator developed for this study, and 2010 drug use data on 1453 California Medicare beneficiaries with HIV who were taking antiretroviral medications. Excess spending is defined as the difference between projected total spending (premium and cost sharing) for the beneficiary's current drug regimen in own plan vs spending for the lowest cost alternative plan. Regression analyses related this excess spending to individual and plan characteristics. We find that beneficiaries pay more for Medicare Part D plans with gap coverage and no deductible. Higher premiums for more extensive coverage exceeded savings in deductible and copayment/coinsurance costs. We conclude that many beneficiaries pay for plan features whose costs exceed their benefits.

Transitioning From Medicaid Disability Coverage to Long-Term Medicare Coverage: The Case of People Living With HIV/AIDS in California.

Medicaid can serve as a bridge to Medicare coverage for the long-term disabled with sufficient covered work experience. We perform multinomial logistic regression on 2007-2010 Medicare and Medicaid claims data to examine transitions to Medicare for people living with HIV/AIDS (PLWHA) in California who had Medicaid coverage in 2007. We find only 16% had obtained Medicare coverage by 2010. African-Americans, women, individuals with schizophrenia diagnoses, alcohol or substance abuse disorders, and any physical comorbidity were significantly less likely than others to obtain Medicare (p < 0.001). This study contributes new information on the impact of eligibility requirements for Medicare long-term disability insurance for PLWHA. About one-third of PLWHA under age 65 are covered by Medicaid. Many PLWHA get stuck in Medicaid because their disability prevents them from obtaining the additional employment experience needed to qualify for Medicare.

Antiretroviral Therapy: Racial Disparities among Publicly Insured Californians with HIV.

Only 43% of Americans with HIV are virally suppressed; the rate is lower for African Americans, even among insured populations. This study uses 2010 Medicare and Medicaid data for HIV-positive Californians to examine how antiretroviral treatment (ART) relates to patient and provider characteristics. Logistic regressions isolated the effect of race/ethnicity on receipt of ART. Over 90% of the full sample received any ART. Nearly 80% of ART users received a recommended combination for at least half the year; half had a recommended combination for 90% of the year. Lacking evaluation and management visits, or seeing only providers with low HIV patient volume lowered the odds of receiving ART. Controlling for other factors, African Americans remained less likely to receive ART at all, or to be covered for 90% of the year with a recommended regimen. The observed racial treatment differentials may lead to important health disparities.

Drug use and emotional distress differentiate unstably- versus stably-housed adults living with HIV who engage in unprotected sex.

Among adults living with HIV, unstable housing is a barrier to health. Stably- and unstably-housed adults living with HIV were assessed for over 25 months. At baseline, unstably-housed adults living with HIV had a more recent HIV diagnosis, higher viral loads, worse physical and mental health, lower rates of antiretroviral therapy use and insurance coverage, and higher rates of hard drug use than stably-housed adults living with HIV. At follow-up, the health of both groups was similar, but unstably-housed adults living with HIV reported significantly more hard drug use and mental health symptoms when compared to the stably-housed adults living with HIV. Drug and mental health risks decreased for both groups, but decreases in unprotected sex were greater among unstably-housed adults living with HIV.

Quality of Care for HIV/AIDS and for Primary Prevention by HIV Specialists and Nonspecialists.

The role of HIV specialists in providing primary care to persons living with HIV/AIDS is evolving, given their increased incidence of comorbidities. Multivariate logit analysis compared compliance with sentinel preventive screening tests and interventions among publicly insured Californians with and without access to HIV specialists in 2010. Quality-of-care indicators [visit frequency, CD4 and viral load (VL) assessments, influenza vaccine, tuberculosis (TB) testing, lipid profile, glucose blood test, and Pap smears for women] were related to patient characteristics and provider HIV caseload. There were 9377 adult Medicare enrollees (71% also had Medicaid coverage) and 2076 enrollees with only Medicaid coverage. Adjusted for patient characteristics, patients seeing providers with greater HIV caseloads (>50 HIV patients) were more likely to meet visit frequency guidelines in both Medicare [98%; confidence interval (CI 97.5-98.2) and Medicaid (97%; CI 96.2-98.0), compared to 60% (CI 57.1-62.3) and 45% (CI 38.3-50.4), respectively, seeing providers without large HIV caseloads (p < 0.001). Patients seeing providers with larger caseloads were significantly more likely to have CD4 (p < 0.001), VL (p < 0.001), and TB testing (p < 0.05). A larger percentage of patients seeing large-volume Medicare providers received influenza vaccinations. Provider caseload was unrelated to lipid or glucose assessments or Pap Smears for women. Patients with access to large-volume providers were more likely to meet clinical guidelines for visits, CD4, VL, tuberculosis testing, and influenza vaccinations, and were not less likely to receive primary preventive care. Substantial insufficiencies remain in both monitoring to assess viral suppression and in preventive care.

Project Masihambisane: a cluster randomised controlled trial with peer mentors to improve outcomes for pregnant mothers living with HIV.

BACKGROUND: Pregnant women living with HIV (WLH) face daily challenges maintaining their own and their babies' health and mental health. Standard Prevention of Maternal to Child Transmission (PMTCT) programs are not designed to address these challenges. METHODS/DESIGN: As part of a cluster randomized controlled trial, WLH are invited to attend four antenatal and four postnatal small group sessions led by a peer WLH (a Peer Mentor). The WLH and their babies are assessed during pregnancy and at one week, six months, and twelve months post-birth. Mobile phones are used to collect routine information, complete questionnaires and remain in contact with participants over time. Pregnant WLH (N = 1200) are randomly assigned by clinic (N = 8 clinics) to an intervention program, called Masihambisane (n = 4 clinics, n = 600 WLH) or a standard care PMTCT control condition (n = 4 clinics; n = 600 WLH). DISCUSSION: Data collection with cellular phones are innovative and effective in low-resource settings. Standard PMTCT programs are not designed to address the daily challenges faced by WLH; Peer Mentors may be useful in supporting WLH to cope with these challenges. TRIAL REGISTRATION: ClinicalTrials.gov registration # NCT00972699.

A randomized controlled trial of home visits by neighborhood mentor mothers to improve children's nutrition in South Africa.

Malnourished children and babies with birth weights under 2500 g are at high risk for negative outcomes over their lifespans. Philani, a paraprofessional home visiting program, was developed to improve nutritional outcomes for young children in South Africa. One "mentor mother" was recruited from each of 37 neighborhoods in Cape Town, South Africa. Mentor mothers were trained to conduct home visits to weigh children under six years old and to support mothers to problem-solve life challenges, especially around nutrition. Households with underweight children were assigned randomly on a 2:1 ratio to the Philani program (n = 500) or to a standard care condition (n = 179); selection effects occurred and children in the intervention households weighed less at recruitment. Children were evaluated over a one-year period (n = 679 at recruitment and n = 638 with at least one follow-up; 94%). Longitudinal random effects models indicated that, over 12 months, the children in the intervention condition gained significantly more weight than children in the control condition. Mentor mothers who are positive peer deviants may be a viable strategy that is efficacious and can build community, and the use of mentor mothers for other problems in South Africa is discussed.

Home visits by neighborhood Mentor Mothers provide timely recovery from childhood malnutrition in South Africa: results from a randomized controlled trial.

BACKGROUND: Child and infant malnourishment is a significant and growing problem in the developing world. Malnourished children are at high risk for negative health outcomes over their lifespans. Philani, a paraprofessional home visiting program, was developed to improve childhood nourishment. The objective of this study is to evaluate whether the Philani program can rehabilitate malnourished children in a timely manner. METHODS: Mentor Mothers were trained to conduct home visits. Mentor Mothers went from house to house in assigned neighborhoods, weighed children age 5 and younger, and recruited mother-child dyads where there was an underweight child. Participating dyads were assigned in a 2:1 random sequence to the Philani intervention condition (n = 536) or a control condition (n = 252). Mentor Mothers visited dyads in the intervention condition for one year, supporting mothers' problem-solving around nutrition. All children were weighed by Mentor Mothers at baseline and three, six, nine and twelve month follow-ups. RESULTS: By three months, children in the intervention condition were five times more likely to rehabilitate (reach a healthy weight for their ages) than children in the control condition. Throughout the course of the study, 43% (n = 233 of 536) of children in the intervention condition were rehabilitated while 31% (n = 78 of 252) of children in the control condition were rehabilitated. CONCLUSIONS: Paraprofessional Mentor Mothers are an effective strategy for delivering home visiting programs by providing the knowledge and support necessary to change the behavior of families at risk.

Relationships over time between mental health symptoms and transmission risk among persons living with HIV.

Relationships between mental health symptoms (anxiety and depression) or a positive state of mind and behavior associated with HIV transmission (substance use and risky sexual behavior) were explored in a longitudinal study of persons living with HIV (PLH; N = 936) who were participants in a transmission-prevention trial. Bivariate longitudinal regressions were used to estimate the correlations between mental health symptoms and HIV-related transmission acts for 3 time frames: at the baseline interview, over 25 months, and from assessment to assessment. At baseline, mental health symptoms were associated with transmission acts. Elevated levels of mental health symptoms at baseline were associated with decreasing alcohol or marijuana use over 25 months. Over 25 months, an increasingly positive state of mind was associated with decreasing alcohol or marijuana use; an increasingly positive state of mind in the immediate intervention condition and increasing depressive symptoms in the lagged condition were related to increasing risky sexual behavior. Our findings suggest that mental health symptoms precede a decrease in substance use and challenge self-medication theories. Changes in mental health symptoms and sexual behavior occur more in tandem.

How much 'skin in the game' do medicare beneficiaries have? The increasing financial burden of health care spending, 1997-2003.

Rising health costs and an aging population present critical policy challenges. This paper examines the financial burden of out-of-pocket health spending among Medicare beneficiaries between 1997 and 2003. Over this period, median out-of-pocket spending as a share of income increased from 11.9 percent to 15.5 percent. In 2003, the 25 percent of beneficiaries with the largest burden spent at least 29.9 percent of their income on health care, while 39.9 percent spent more than a fifth of their income on health care. Results suggest that sustained increases in out-of-pocket spending could make health care less affordable for all but the highest-income beneficiaries.

Fatigue in long-term breast carcinoma survivors: a longitudinal investigation.

BACKGROUND: A longitudinal study was designed to evaluate the prevalence, persistence, and predictors of posttreatment fatigue in breast carcinoma survivors. METHODS: A sample of 763 breast carcinoma survivors completed questionnaires at 1-5 and 5-10 years after diagnosis, including the RAND 36-item Health Survey, Center for Epidemiological Studies - Depression scale (CES-D), Breast Cancer Prevention Trial Symptom Checklist, and demographic and treatment-related measures. RESULTS: Approximately 34% of study participants reported significant fatigue at 5-10 years after diagnosis, which is consistent with prevalence estimates obtained at 1-5 years after diagnosis. Approximately 21% reported fatigue at both assessment points, indicating a more persistent symptom profile. Longitudinal predictors of fatigue included depression, cardiovascular problems, and type of treatment received. Women treated with either radiation or chemotherapy alone showed a small improvement in fatigue compared with those treated with both radiation and chemotherapy. CONCLUSIONS: Fatigue continues to be a problem for breast carcinoma survivors many years after cancer diagnosis, with 21% reporting persistent problems with fatigue. Several factors that may contribute to long-term fatigue are amenable to intervention, including depression and comorbid medical conditions.

Does greater Medicare HMO enrollment cause adverse selection into Medigap?

This paper examines the interaction between public and private insurance in the context of the US Medicare program, which serves those aged 65 and older as well as the disabled who meet specific eligibility requirements. Specifically, the paper examines the extent to which increasing enrollment in Medicare managed care (which provides more comprehensive coverage than basic Medicare) influences premiums in the privately purchased Medicare supplemental insurance market (called 'Medigap'). We employ a fixed effects instrumental variables approach to analyze the association between premiums charged by two large Medigap insurers and Medicare HMO penetration rates, examining over 60 geographic areas during the period 1994-2000. It is hypothesized that greater Medicare HMO penetration will lead to adverse selection into the Medigap market, resulting in higher premiums. The findings suggest a moderate upward effect on premiums, with elasticities ranging from 0.09 to 0.25. Controlling for other factors, moving from a 12% to a 22% Medicare HMO penetration rate would raise average Medigap premiums from $1,314 to $1,615. We discuss the implications of these results with respect to the design of national health care systems that include both public and private insurers.

Perceptions of positive meaning and vulnerability following breast cancer: predictors and outcomes among long-term breast cancer survivors.

BACKGROUND: Survival rates for women with early-stage breast cancer have increased significantly in recent years. However, little is known about the long-term impact of the cancer experience on women's psychological functioning. Theoretical and descriptive accounts suggest that cancer may evoke both perceptions of vulnerability and positive meaning, with potentially different effects on mental health. PURPOSE: This study was designed to evaluate the prevalence and stability of these perceptions in a large sample of breast cancer survivors, to identify their antecedents, and to determine their impact on long-term adjustment. METHODS: Breast cancer survivors (N = 763) were assessed longitudinally at 1 to 5 years and 5 to 10 years postdiagnosis. Participants completed surveys assessing perceptions of positive meaning and vulnerability and standard measures of psychological adjustment and quality of life. RESULTS: The majority of women reported positive changes in outlook and priorities as well as feelings of vulnerability at both assessment points. Consistent with hypotheses, results showed that perceptions of positive meaning and vulnerability were positively correlated and were both associated with factors that increased the disruptiveness of the cancer experience. Vulnerability was strongly associated with negative affect, whereas meaning was associated with positive affect in cross-sectional and longitudinal analyses. CONCLUSIONS: Results suggest that a cancer diagnosis may lead to enduring feelings of vulnerability as well as positive changes in meaning; however, these perceptions have very different mental health correlates.

Does a history of childhood sexual abuse affect sexual outcomes in breast cancer survivors?

PURPOSE: Little is known about a history of childhood sexual abuse (CSA) in breast cancer survivors and its relationship to sexual functioning after cancer. As part of a larger survey study examining sexuality and intimacy in breast cancer survivors, we conducted in-person interviews with a subsample of participants. METHODS: A total of 147 women in Los Angeles, CA, and Washington, DC, completed a structured interview that addressed sexual socialization and a history of sexual abuse. Trained female interviewers conducted the interviews. Descriptive statistics and regression analyses were used to examine the prevalence of CSA, and its potential impact on sexual health and functioning. RESULTS: One in three women reported at least one CSA incident. Among women who had experienced CSA, 71% reported a single incident, and 22% reported a penetrative form of sexual contact. In multivariate regression analyses examining physical and psychological aspects of sexuality and body image, CSA was not a significant predictor of physical discomfort. However, a history of penetrative CSA was a significant predictor of psychological discomfort (P = .02). CONCLUSION: The prevalence of CSA in this sample was similar to the general population literature on this topic. In this small sample, a past history of CSA did not contribute significantly to the physical discomforts associated with sexual intimacy after breast cancer; however, our findings suggest that a past history of penetrative CSA is associated with increased psychological discomfort, and may warrant additional examination in future research.

Quality of life of breast cancer survivors after a recurrence: a follow-up study.

Previous studies on breast cancer recurrence provide a mixed picture of the quality of life of women following a recurrence. To clarify the picture, the present study addresses some previous methodological concerns by offering a multidimensional assessment with follow-up, a matched comparison group of disease-free survivors, and a closer look at the nature of recurrence (local versus metastatic). Fifty-Four of 817 women who participated in an earlier study experienced a recurrence at follow-up, and are compared to a matched sample of 54 women who remained disease-free. Analyses indicate that women who had a recurrence report significantly poorer functioning on various health-related quality of life (HRQOL) domains compared to women who remained disease-free. However, the differences appear to be largely due to the poorer HRQOL of women with metastatic disease. Although women who had a recurrence report good mood, low stress, and good quality of interpersonal relationships, they report significantly higher cancer-specific stress compared to disease-free women at follow-up. Women who had a recurrence also report experiencing both more meaning and vulnerability as a result of breast cancer than disease-free women, but report similar levels of spirituality and benefit-finding at follow-up as disease-free women. These results suggest that although women report relatively good psychosocial adjustment following a recurrence, cancer-specific domains of quality of life are most likely to be negatively affected. These results may be useful in identifying individuals with breast cancer recurrences who are most in need of psychosocial services.

The distributional consequences of a Medicare premium support proposal.

This article analyzes the distributional consequences of enacting a particular premium support proposal known as Breaux-Frist I. Under the proposal, the federal government would contribute a certain amount toward the purchase of Medicare coverage, based on the premiums charged by different health plans. Beneficiaries could choose something akin to the traditional fee-for-service option or a privately sponsored ealth plan such as a health maintenance organization. The article simulates the expected distributional impacts in three areas: among beneficiaries who choose to retain fee-for-service coverage, between different geographic areas, and according to various beneficiary characteristics. We find that the legislation would result in increased premiums for beneficiaries remaining in the Medicare fee-for-service program as a result of unfavorable selection; lead to a geographic redistribution in premium payments, with those living in areas with high levels of Medicare expenditures paying more; and a much lower financial burden than is the case now for near-poor beneficiaries who do not have full Medicaid coverage. Finally, the article discusses how these results compare to those that may occur under the premium support demonstration project, beginning in 2010, established under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003.

Does open enrollment control premiums? A case study from the "Medigap" market.

This article analyzes a change in "Medigap" regulations that occurred in Missouri in 1999. It allows Medicare beneficiaries in the state to switch to a different carrier each year so long as they retain the same standardized policy type, without losing their open enrollment privileges. The analysis is based on a comparison of various outcomes in Missouri and those in two comparison states, Kansas and Florida. We found little evidence that the policy change affected premiums charged by insurance carriers in Missouri, but conclude that other desirable aspects of the change make it potentially attractive for other states to follow.
