Abstract
INTRODUCTION Expanding HIV pre-exposure prophylaxis (PrEP) use is key to goals for lowering new HIV infections in the U.S. by 90% between 2022 and 2030. Unfortunately, youth aged 16-24 have the lowest PrEP use of any age group and the highest HIV incidence rates. METHODS To examine the relationship between HIV seroconversion and PrEP uptake, adherence, and continuity, we used survival analysis and multivariable logistic regression on data of 895 youth at-risk for HIV infection enrolled in Adolescent Trials Network for HIV Medicine protocol 149 in Los Angeles and New Orleans, assessed at 4-month intervals over 24 months. RESULTS The sample was diverse in race/ethnicity (40% Black, 28% Latine, 20% White). Most participants (79%) were cis-gender gay/bisexual male but also included 7% transgender female and 14% trans masculine and nonbinary youth. Self-reported weekly PrEP adherence was high (98%). Twenty-seven participants acquired HIV during the study. HIV incidence among PrEP users (3.12 per 100 person year [PY]) was higher than those who never used PrEP (2.53/100 PY). The seroconversion incidence was highest among PrEP users with discontinuous use (3.36/100 PY). If oral PrEP users were adherent using 2-monthly long-acting injectables, our estimate suggests 2.06 infections per 100 PY could be averted. CONCLUSIONS Discontinuous use of PrEP may increase risk of HIV acquisition among youth at higher risk for HIV infection and indications for PrEP. Thus, to realize the promise of PrEP in reducing new HIV infections, reducing clinical burdens for PrEP continuation are warranted.

Abstract
Long-acting injectable antiretroviral medications are new to HIV treatment. People with HIV may benefit from a treatment option that better aligns with their preferences, but could also face new challenges and barriers. Authors from the fields of HIV, substance use treatment, and mental health collaborated on this commentary on the issues surrounding equitable implementation and uptake of LAI ART by drawing lessons from all three fields. We employ a socio-ecological framework beginning at the policy level and moving through the community, organizational, interpersonal, and patient levels. We look at extant literature on the topic as well as draw from the direct experience of our clinician-authors.

Abstract
One of the pillars of efforts in the US to curb HIV incidence is pre-exposure prophylaxis (PrEP). We examined racial/ethnic and sex disparities in PrEP uptake among California Medicaid enrollees. Claims data from 2019 identified enrollees and PrEP users in each racial/ethnic, sex, and age group, yielding crude uptake rates. We then predicted age-adjusted uptake rates from multivariable logit regressions and divided PrEP uptake estimates by each group's number of new HIV diagnoses to estimate PrEP-to-need ratios. Predicted uptake was highest for White (0.29 percent) and Black (0.23 percent) males and lowest (0.16 percent) for Hispanic males. Rates for males exceeded those for females; however, Black females had twice the rate of PrEP uptake of White females. Black males and females and Hispanic males had PrEP-to-need ratios that were less than one-third (4.0-6.3) those of Asian and White males and females (14.4-19.9). Low PrEP use rates and disparities in uptake threaten efforts to end the HIV epidemic. Policy makers must craft the rollout of innovations such as PrEP in a manner that narrows HIV disparities instead of widening them.

Abstract
One-quarter of annual Medicare expenses in the traditional program (non-Medicare Advantage) are expended for 5% of Medicare enrollees, with much of this expenditure occurring in the last year of life. Hospice use may reduce end-of-life costs. However, evidence has been inconclusive due to sample selection and differences in insurance coverage for hospice. Claims data for HIV-positive Californians enrolled in Medicare who died in the period 2008 to 2010 were used to examine the relationship between hospice use and costs in the last 6 months of life. Logit estimates related hospice use to sickness levels and demographics. Inpatient and outpatient costs were analyzed separately. Logit regressions examined hospitalization probability. Robust regressions were used to examine the determinants of conditional inpatient costs and non-inpatient costs. Bootstrapped post-estimates were then used to determine the marginal probability of costs for the sample by hospice use. Hospice users have greater disease burden and are less likely to be African American. Controlling for disease burden, hospice users would have non-inpatient costs that were $14 771 greater than hospice non-users, but inpatient costs that were $20 522 lower. Thus, hospice reduces costs on net. Hospice is chosen by patients with more comorbidities. Controlling for these comorbidities, hospice use is associated with lower inpatient costs, greater non-inpatient costs and reduced end-of-life costs.

Abstract
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.

Abstract
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.

Abstract
In light of South Africa's high prenatal HIV prevalence and infant mortality rate, a cluster randomized controlled trial was conducted to evaluate an intervention called Philani+, which used community health workers (known as Mentor Mothers) to deliver pre- and postnatal home visits in Cape Town, South Africa, to improve maternal and child health. We assessed the costs and benefits of this intervention and made comparisons with other scenarios that depicted increased capacity and provision of nurse-delivered care. The recurrent cost of the twenty-four-month intervention was US$80,001. The major health outcomes analyzed were differences in the proportion of infants who were low birthweight, stunted, and suboptimally breastfed between intervention and control groups. Each case of low birthweight averted cost US$2,397; of stunted growth, US$2,454; and of suboptimal breastfeeding, US$1,618. Employment of community health workers was cost saving compared to that of nurses. Philani+ improved child health at a relatively low cost, considering the health system costs associated with low birthweight and undernutrition. The model could be suitable for replication in low-resource settings to improve child health in other countries.

Abstract
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.

Abstract
BACKGROUND Men who have sex with men with HIV have high sexually transmitted infection (STI) incidence. Thus, the Centers for Disease Control and Prevention (CDC) recommends at least yearly STI screening of HIV-infected individuals. METHODS We calculated testing rates for syphilis, chlamydia, and gonorrhea among HIV-positive Californians with Medicare or Medicaid insurance in 2010. Logistic regressions estimated how testing for each bacterial STI relates to demographic and provider factors. RESULTS Fewer than two-thirds of HIV-positive Medicare and fewer than three-quarters of Medicaid enrollees received a syphilis test in 2010. Screenings for chlamydia or gonorrhea were less frequent: approximately 30% of Medicare enrollees were tested for chlamydia or gonorrhea in 2010, but higher proportions of Medicaid enrollees were tested (45%-46%). Only 34% of HIV-positive Medicare enrollees who were tested for syphilis were also screened for chlamydia or gonorrhea on the same day. Nearly half of Medicaid enrollees were tested for all 3 STIs on the same day. Patients whose providers had more HIV experience had higher STI testing rates. CONCLUSIONS Testing rates for chlamydia and gonorrhea infection are low, despite the increase in these infections among people living with HIV and their close association with HIV transmission. Interventions to increase STI testing include the following: prompts in the medical record to routinely conduct syphilis testing on blood drawn for viral load monitoring, opt-out consent for STI testing, and provider education about the clinical importance of STIs among HIV-positive patients. Last, it is crucial to change financial incentives that discourage nucleic acid amplification testing for rectal chlamydia and gonorrhea infections.

Abstract
BACKGROUND Antiretroviral therapy has increased longevity for people living with HIV (PLWH). As a result, PLWH increasingly experience the common diseases of aging and the resources needed to manage these comorbidities are increasing. This paper characterizes the number and types of comorbidities diagnosed among PLWH covered by Medicare and examines how non-HIV comorbidities relate to outpatient, inpatient, and pharmaceutical expenditures. METHODS The study examined Medicare expenditures for 9767 HIV-positive Californians enrolled in Medicare in 2010 (7208 persons dually covered by Medicare and Medicaid and 2559 with Medicare only). Costs included both out of pocket costs and those paid by Medicare and Medicaid. Comorbidities were determined by examining diagnosis codes. FINDINGS Medicare expenditures for Californians with HIV averaged $47,036 in 2010, with drugs accounting for about 2/3 of the total and outpatient costs 19% of the total. Inpatient costs accounted for 18% of the total. About 64% of the sample had at least one comorbidity in addition to HIV. Cross-validation showed that adding information on comorbidities to the quantile regression improved the accuracy of predicted individual expenditures. Non-HIV comorbidities relating to health habits-diabetes, hypertension, liver disease (hepatitis C), renal insufficiency-are common among PLWH. Cancer was relatively rare, but added significantly to cost. Comorbidities had little effect on pharmaceutical costs, which were dominated by the cost of antiretroviral therapy, but had a major effect on hospital admission. CONCLUSIONS Comorbidities are prevalent among PLWH and add substantially to treatment costs for PLWH. Many of these comorbidities relate to health habits that could be addressed with additional prevention in ambulatory care, thereby improving health outcomes and ultimately reducing costs.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Historically, California supplemented federal funding of HIV prevention and testing so that Californians with HIV could become aware of their infection and obtain lifesaving treatment. However, budget deficits in 2009 led the state to eliminate its supplemental funding for HIV prevention. We analyzed the impact of California's HIV resource allocation change between state fiscal years 2009 and 2011. We found that the number of HIV tests declined 19 percent, from 66,629 to 53,760, in local health jurisdictions with high HIV burden. In low-burden jurisdictions, the number of HIV tests declined 90 percent, from 20,302 to 2,116. New diagnoses fell from 2,434 in 2009 to 2,235 in 2011 (calendar years) in high-burden jurisdictions and from 346 to 327 in low-burden ones. California's budget crunch prompted state and local programs to redirect remaining HIV funds from risk reduction education to testing activities. Thus, the impact of the budget cuts on HIV tests and new HIV diagnoses was smaller than might have been expected given the size of the cuts. As California's fiscal outlook improves, we recommend that the state restore supplemental funding for HIV prevention and testing.

Abstract
BACKGROUND The Centers for Disease Control and Prevention (CDC) estimates that 156,300 (95% CI 144,100-165,900) Americans living with HIV in 2012 were unaware of their infection. To increase knowledge of HIV status, CDC guidelines seek to make HIV screening a routine part of medical care. This paper examines how routinely California primary care providers test for HIV and how providers' knowledge of California's streamlined testing requirements, use of sexual histories, and having an electronic medical record prompt for HIV testing, relate to test offers. METHODS We surveyed all ten California health plans offered under health reform's Insurance Exchange (response rate = 50%) and 322 primary care providers to those plans (response rate = 19%) to assess use of HIV screening and risk assessments. RESULTS Only 31.7% of 60 responding providers reported offering HIV tests to all or most new enrollees and only 8.8% offered an HIV test of blood samples all or most of the time despite the California law requiring that providers offer HIV testing of blood samples in primary care settings. Twenty-eight of the 60 providers (46.6%) were unaware that California had reduced barriers to HIV screening by eliminating the requirement for written informed consent and pre-test counseling. HIV screening of new enrollees all or most of the time was reported by 53.1% of the well-informed providers, but only 7.1% of the less informed providers, a difference of 46 percentage points (95% CI: 21.0%-66.5%). Providers who routinely obtained sexual histories were 29 percentage points (95% CI: 0.2%-54.9%) more likely to screen for HIV all or most of the time than those who did not ask sexual histories. CONCLUSION Changing HIV screening requirements is important, but not sufficient to make HIV testing a routine part of medical care. Provider education to increase knowledge about the changed HIV testing requirements could positively impact testing rates.

Abstract
OBJECTIVES We sought to identify people living with HIV/AIDS from Medicare and Medicaid claims data to estimate Medicaid costs for treating HIV/AIDS in California. We also examined how alternate methods of identifying the relevant sample affect estimates of per capita costs. METHODS We analyzed data on Californians enrolled in Medicaid with an HIV/AIDS diagnosis reported in 2007 Medicare or Medicaid claims data. We compared alternative selection criteria by examining use of antiretroviral drugs, HIV-specific monitoring tests, and medical costs. We compared the final sample and average costs with other estimates of the size of California's HIV/AIDS population covered by Medicaid in 2007 and their average treatment costs. RESULTS Eighty-seven percent (18,290) of potentially identifiable HIV-positive individuals satisfied at least 1 confirmation criterion. Nearly 80% of confirmed observations had claims for HIV-specific tests, compared with only 3% of excluded cases. Female Medicaid recipients were particularly likely to be miscoded as having HIV. Medicaid treatment spending for Californians with HIV averaged $33,720 in 2007. CONCLUSIONS The proposed algorithm displays good internal and external validity. Accurately identifying HIV cases in claims data is important to avoid drawing biased conclusions and is necessary in setting appropriate HIV managed-care capitation rates.

Abstract
To determine if a structural intervention of providing one condom a week to inmates in the Los Angeles County Men’s Central Jail MSM unit reduces HIV transmissions and net social cost, we estimated numbers of new HIV infections (1) when condoms are available; and (2) when they are not. Input data came from a 2007 survey of inmates, the literature and intervention program records. Base case estimates showed that condom distribution averted 1/4 of HIV transmissions. We predict .8 new infections monthly among 69 HIV-negative, sexually active inmates without condom distribution, but .6 new infections with condom availability. The discounted future medical costs averted due to fewer HIV transmissions exceed program costs, so condom distribution in jail reduces total costs. Cost savings were sensitive to the proportion of anal sex acts protected by condoms, thus allowing inmates more than one condom per week could potentially increase the program’s effectiveness.

Abstract
Two recent changes in health policy will likely negatively impact state budgets and the health of low-income Californians with chronic disease. The new cost-sharing for medical visits, pharmaceuticals, and inpatient stays in California's Medcaid program (Medi-Cal) and the exclusion of the undocumented and individuals who have been legal residents for less than five years from the insurance expansions that The Patient Protection and Affordable Care Act of 2010 provides will reduce medical care utilization and may raise, rather than lower, state costs. Based on historical Medi-Cal utilization patterns, people living with HIV (PLWH) would average $514 in cost-sharing fees annually. The undocumented may lose coverage entirely and face even higher costs. The charges are high relative to the low incomes of both Medi-Cal recipients and the undocumented and are likely to discourage relatively inexpensive, but productive, medical care. Increasing patient costs harms patient health, harms public health, and increases state spending on medical care.

Abstract
The purpose of this study was to identify factors that may facilitate or impede future adoption of preexposure prophylaxis (PrEP) for HIV prevention among gay and bisexual men in HIV-serodiscordant relationships. This qualitative study utilized semistructured interviews conducted with a multiracial/-ethnic sample of 25 gay and bisexual HIV-serodiscordant male couples (n=50 individuals) recruited from community settings in Los Angeles, CA. A modified grounded theory approach was employed to identify major themes relating to future adoption of PrEP for HIV prevention. Motivators for adoption included protection against HIV infection, less concern and fear regarding HIV transmission, the opportunity to engage in unprotected sex, and endorsements of PrEP's effectiveness. Concerns and barriers to adoption included the cost of PrEP, short- and long-term side effects, adverse effects of intermittent use or discontinuing PrEP, and accessibility of PrEP. The findings suggest the need for a carefully planned implementation program along with educational and counseling interventions in the dissemination of an effective PrEP agent.

Abstract
Orally administered preexposure prophylaxis is an innovative and controversial HIV prevention strategy involving the regular use of antiretroviral medications by uninfected individuals. Antiretroviral medications protect against potential HIV infection by reducing susceptibility to the virus. Recent clinical trial results indicate that preexposure prophylaxis can be safe and efficacious for men who have sexual intercourse with men, yet there remain policy considerations surrounding costs, opportunity costs, and ethical issues that must be addressed before broad implementation in the United States.

Abstract
The effectiveness of male circumcision in preventing transmission of HIV from females to males has been established. Those who are now advocating its widespread use face many challenges in convincing policy-makers and the public of circumcision’s value. We suggest that frames are a useful lens for communicating public health messages that may help promote adoption of circumcision. Frames relate to how individuals and societies perceive and understand the world. Existing frames are often hard to shift, and should be borne in mind by advocates and program implementers as they attempt to promote male circumcision by invoking new frames. Frames differ across and within societies, and advocates must find ways of delivering resonant messages that take into account prior perceptions and use the most appropriate means of communicating the benefits and value of male circumcision to different audiences.

Abstract
Now that male circumcision has been shown to have a protective effect for men against HIV infection when engaging in vaginal intercourse with HIV-infected women, the research focus needs to shift towards the operational studies that can pave the way for effective implementation of circumcision programs. Behavioral research is needed to find out how people perceive the procedure and the barriers to and facilitators of uptake. It should also assess the risk of an increase in unsafe sex after circumcision. Social research must examine cultural perceptions of the practice, in Africa and beyond, including how likely uncircumcised communities are to access surgery and what messages are needed to persuade them. Advocates of male circumcision would benefit from research on how to influence health policy-makers, how best to communicate the benefits to the public, and how to design effective delivery models.

Abstract
Compared with other developed countries, the United States has an inefficient and expensive health care system with poor outcomes and many citizens who are denied access. Inefficiency is increased by the lack of an integrated system that could promote an optimal mix of personal medical care and population health measures. We advocate a health trust system to provide core medical benefits to every American, while improving efficiency and reducing redundancy. The major innovation of this plan would be to incorporate existing private health insurance plans in a national system that rebalances health care spending between personal and population health services and directs spending to investments with the greatest long-run returns.

Abstract
OBJECTIVE We sought to determine whether lack of state Medicaid coverage for infant male circumcision correlates with lower circumcision rates. METHODS We used data from the Nationwide Inpatient Sample on 417 282 male newborns to calculate hospital-level circumcision rates. We used weighted multiple regression to correlate hospital circumcision rates with hospital-level predictors and state Medicaid coverage of circumcision. RESULTS The mean neonatal male circumcision rate was 55.9%. When we controlled for other factors, hospitals in states in which Medicaid covers routine male circumcision had circumcision rates that were 24 percentage points higher than did hospitals in states without such coverage (P<.001). Hospitals serving greater proportions of Hispanic patients had lower circumcision rates; this was not true of hospitals serving more African Americans. Medicaid coverage had a smaller effect on circumcision rates when a hospital had a greater percentage of Hispanic births. CONCLUSIONS Lack of Medicaid coverage for neonatal male circumcision correlated with lower rates of circumcision. Because uncircumcised males face greater risk of HIV and other sexually transmitted infections, lack of Medicaid coverage for circumcision may translate into future health disparities for children born to poor families covered by Medicaid.

Abstract
We examined changes and correlates of sexual risk behavior of men who have sex with men (MSM) compared with heterosexual men and women over three time periods. Data from the 1997, 1999, and 2003 Los Angeles County Health Surveys, a population-based telephone survey, were analyzed to examine the association of sociodemographic and health-related factors with sexual risk behaviors among the three groups. In each time period, MSM reported a significantly greater percentage of sexual risk (i.e., both inconsistent condom use and multiple sex partners in the past 12 months) compared with heterosexual men and women. Multivariate analyses indicated that MSM and heterosexual men reported greater sexual risk than heterosexual women. Respondents who were younger, U.S. born, reported heavy alcohol consumption, or had been tested for HIV in the past 24 months were more likely to report sexual risk behavior. The findings suggest the need for continued targeted prevention for MSM and prevention efforts for segments of the general population at elevated risk for HIV.

Abstract
This article examines how proximity to the nearest publicly funded test site affects HIV testing. Using a sample of 5,361 Los Angeles County adults, multinomial logit models estimated simultaneously the likelihood of (1) obtaining an HIV test in the prior 2 years, and (2) testing in a private physician's office, a publicly funded medical clinic, or in a nonmedical setting, such as a bar or bathhouse. Low-income Los Angeles residents rely on publicly funded sites for HIV testing. When public sites are more distant, poor individuals are less likely to use them and less likely to get tested. Distance from public sites does not affect HIV testing among the nonpoor. To encourage HIV testing among the groups where HIV is growing fastest, public health agencies must keep the time and money costs of HIV testing low.

Abstract
We examine whether U.S. states can use their market power to reduce the costs of supplying prescription drugs to uninsured and underinsured persons with HIV through a public program, the AIDS Drug Assistance Program (ADAP). Among states that purchase drugs from manufacturers and distribute them directly to clients, those that purchase a greater volume pay lower average costs per prescription. Among states depending on retail pharmacies to distribute drugs and then claiming rebates from manufacturers, those that contract with smaller numbers of pharmacy networks have lower average costs. Average costs per prescription do not differ between the two purchase methods.

Abstract
HIV testing identifies HIV-positive persons, allowing for reduced future HIV transmission while simultaneously providing policy makers with surveillance data to inform policy planning. If current costs of HIV testing were reduced, these funds could be redirected to increase testing rates or to expand treatment. The cost of testing is lowered and impact increased if noninvasive (oral and urine), rapid-testing modalities are utilized, pretest counseling uses cost-efficient counseling methods (e.g., video, pamphlets, small group discussions), and opt-out consent strategies are implemented while posttest counseling is more narrowly targeted to HIV-positive persons. Rather than relying on one international standard, customizing HIV testing procedures to local environments may be more efficient and effective. In the United States, laboratories with substantial HIV testing revenues are likely to be most resistant to altering current practices. However, AIDS researchers, policy makers, and advocates may dramatically influence the epidemic's course by encouraging flexibility and innovation in HIV-testing guidelines.

Abstract
The objective of this study was to assess the socioeconomic circumstances of older patients with HIV and acquired immunodeficiency syndrome (AIDS). The investigators compared subjects from a national probability sample of 2,864 respondents from the HIV Cost and Services Utilization Study (HCSUS, 1996) with 9,810 subjects from Wave 1 (1992) of the Health and Retirement Survey (HRS). Bivariate analyses compare demographic characteristics, financial resources, and health insurance status between older and younger adults and between older adults with HIV and the general population. It was found that nearly 10% of the HIV-positive population is between the ages of 50 and 61 years. Older whites with HIV are mostly homosexual men who are more well educated, more often privately insured, and more financially stable than the HIV population as a whole. In contrast, older minorities with HIV possess few economic resources in either absolute or relative terms. The success of new drug therapies and the changing demographics of the HIV population necessitate innovative policies that promote labor force participation and continuous access to antiretroviral therapies.

Abstract
OBJECTIVES The aim of this study was to estimate the point prevalence of psychotropic medication use, and to describe relationships between child-level characteristics, provider type, and medication use among children in the child welfare system. METHODS The National Survey of Child and Adolescent Well-Being is the first nationally representative study of children coming into contact with the child welfare system. We used data from its baseline and 12-month follow-up waves, and conducted weighted bivariate analyses on a sample of 3114 children and adolescents, 87% of whom were residing in-home. RESULTS Overall, 13.5% of children in child welfare were taking psychotropic medications in 2001-2002. Older age, male gender, Caucasian race/ethnicity, history of physical abuse, public insurance, and borderline scores on the internalizing and externalizing subscales of the Child Behavior Checklist were associated with higher proportions of medication use. African-American and Latino ethnicities, and a history of neglect, were associated with lower proportions of medication use. CONCLUSIONS These national estimates suggest that children in child welfare settings are receiving psychotropic medications at a rate between 2 and 3 times that of children treated in the community. This suggests a need to further understand the prescribing of psychotropic medications for child welfare children.

Abstract
Michael Grossman's seminal model stressed that health production requires both goods and time. Yet recent empirical health research focuses primarily on personal medical care to the exclusion of other inputs to health. Future research should place greater emphasis on the roles of non-medical consumption goods, population level inputs and time in producing health capital. Improved information technology will allow researchers to dissect how education promotes efficiency in combining goods and time to produce health. Economic analyses of child health, which is the antecedent of adult health, must proceed in tandem with medical advances in understanding health development in childhood.

Abstract
With the approval of rapid HIV testing and the expected broader use of this technology, community-based organizations incorporating its use face both opportunities and challenges. The primary advantage of rapid testing is the ability to dramatically increase the number of individuals who become aware of their HIV status. Individuals will be able to test for HIV and learn their results in the same session. Many challenges exist, however, for those agencies considering offering rapid HIV testing. For example, given the potential for an increase in the number of individuals seeking rapid testing, there will be a need to ensure that the individuals who are at highest risk for HIV are being tested. In addition, given that rapid testing will be done in a single session, it will be necessary to consider how to effectively address a client's behaviors and attitudes concerning high-risk activities. New types of referrals may also need to be developed, such as for individuals who receive a preliminary positive HIV test result and who will need to return for a confirmatory result. In addition, those receiving confirmatory positive results will require immediate linkages to a variety of services, including medical, mental health, and social services. Also, counselors providing immediate test results may need additional skills and support to address the stress associated with implementing this new technology. Community agencies will need to utilize this technology in a way that maximizes its potential to identify cases of HIV and links individuals as quickly as possible to needed services.

Abstract
OBJECTIVE To determine the sensitivity of employees' health insurance decisions--including the decision to not choose health maintenance organization or fee-for-service coverage--during periods of rapidly escalating healthcare costs. STUDY DESIGN A retrospective cohort study of employee plan choices at a single large firm with a "cafeteria-style" benefits plan wherein employees paid all the additional cost of purchasing more generous insurance. METHODS We modeled the probability that an employee would drop coverage or switch plans in response to employee premium increases using data from a single large US company with employees across 47 states during the 3-year period of 1989 through 1991, a time of large premium increases within and across plans. RESULTS Premium increases induced substantial plan switching. Single employees were more likely to respond to premium increases by dropping coverage, whereas families tended to switch to another plan. Premium increases of 10% induced 7% of single employees to drop or severely cut back on coverage; 13% to switch to another plan; and 80% to remain in their existing plan. Similar figures for those with family coverage were 11%, 12%, and 77%, respectively. Simulation results that control for known covariates show similar increases. When faced with a dramatic increase in premiums--on the order of 20%--nearly one fifth of the single employees dropped coverage compared with 10% of those with family coverage. CONCLUSIONS Employee coverage decisions are sensitive to rapidly increasing premiums, and single employees may be likely to drop coverage. This finding suggests that sustained premium increases could induce substantial increases in the number of uninsured individuals.

Abstract
In the United States, universal public insurance is only available for the elderly. But unlike most other major diseases, HIV/AIDS predominantly affects the nonelderly. The result is that insurance availability and public programme participation are linked to disease progression in a complicated way. This paper uses data from a unique, nationally representative sample of HIV-infected adults receiving medical care, to describe the relationship between disease progression and insurance coverage in the United States. We find that public insurance is the predominant source of coverage for those in care for HIV, and that coverage increases as disease progresses. Those with public coverage have substantial work experience and earnings capacity, but do not work. This suggests that reforms allowing HIV positive (+) patients to maintain public coverage while returning to work could increase employment and earnings significantly. More speculatively, it suggests that the United States system for financing health care is not well-equipped to deal with epidemics that afflict a population in its prime work years.

Abstract
OBJECTIVES This study identified age-related differences in diagnosis and progression of HIV by analyzing a nationally representative sample of HIV-infected adults under care in the United States. METHODS We compared older (> or = 50 years) and younger participants stratified by race/ethnicity. Regression models controlled for demographic, therapeutic, and clinical factors. RESULTS Older non-Whites more often had HIV diagnosed when they were ill. Older and younger patients were clinically similar. At baseline, however, older non-Whites had fewer symptoms and were less likely to have AIDS, whereas at follow-up they had a trend toward lower survival. CONCLUSIONS Later HIV diagnosis in non-Whites merits public health attention; clinical progression in this group requires further study.

Abstract
BACKGROUND The introduction of expensive but very effective antiviral medications has led to questions about the effects on the total use of resources for the care of patients with human immunodeficiency virus (HIV) infection. We examined expenditures for the care of HIV-infected patients since the introduction of highly active antiretroviral therapy. METHODS We interviewed a random sample of 2864 patients who were representative of all American adults receiving care for HIV infection in early 1996, and followed them for up to 36 months. We estimated the average expenditure per patient per month on the basis of self-reported information about care received. RESULTS The mean expenditure was $1,792 per patient per month at base line, but it declined to $1,359 for survivors in 1997, since the increases in pharmaceutical expenditures were smaller than the reductions in hospital costs. Use of highly active antiretroviral therapy was independently associated with a reduction in expenditures. After adjustments for the interview date, clinical status, and deaths, the estimated annual expenditure declined from $20,300 per patient in 1996 to $18,300 in 1998. Expenditures among subgroups of patients varied by a factor of as much as three. Pharmaceutical costs were lowest and hospital costs highest among underserved groups, including blacks, women, and patients without private insurance. CONCLUSIONS The total cost of care for adults with HIV infection has declined since the introduction of highly active antiretroviral therapy. Expenditures have increased for medications but have declined for other services. However, there are large variations in expenditures across subgroups of patients.

Abstract
There is substantial variation in the generosity of public assistance programs that affect HIV+ patients, and these differences should affect the economic outcomes associated with HIV infection. This article uses data from a nationally representative sample of HIV+ patients to assess how differences across states in Medicaid and AIDS Drug Assistance Programs (ADAP) affect costs and labor market outcomes for HIV+ patients in care in that state. Making ADAP programs more generous in terms of drug coverage would reduce per patient total monthly costs, mainly through a reduction in hospitalization costs. In contrast, expanding ADAP eligibility by increasing the income threshold would increase the total cost of care. Expanding eligibility for Medicaid through the medically needy program would increase per patient total costs, but full-time employment would increase and so would monthly earnings. The authors conclude that more generous state policies toward HIV+ patients--especially those designed to provide access to efficacious treatment--could improve the economic outcomes associated with HIV.

Abstract
This paper examines utilization of paid and unpaid home health care using data from a nationally representative sample of HIV-positive persons receiving medical care in early 1996 (N = 2,864). Overall, 21.0% used any home care, 12.2% used paid care and 13.6% used unpaid care. Most (70.0%) users of home care received care from only one type of provider. Substantially more hours of unpaid than paid care were used. We also found evidence of a strong association between type of service used and type of care provider: 62.4% of persons who used nursing services only received paid care only; conversely, 55.5% of persons who used personal care services only received care only from unpaid caregivers. Use of home care overall was concentrated among persons with AIDS: 39.5% of persons with AIDS received any home health care, compared to 9.5% of those at earlier disease stages. In addition to having an AIDS diagnosis, logistic regression analyses indicated that other need variables significantly increased utilization; a higher number of HIV-related symptoms, lower physical functioning, less energy, a diagnosis of CMV and a recent hospitalization each independently increased the odds of overall home care utilization. Sociodemographic variables had generally weak relationships with overall home care utilization. Among users of home care, non-need variables had more influence on use of paid than unpaid care. Both paid and unpaid home health care is a key component of community-based systems of care for people with HIV infection. The results presented in this paper are the first nationally representative estimates of home care utilization by persons with HIV/AIDS and are discussed with reference to policy and future research.

Abstract
OBJECTIVE To examine the trade-offs inherent in selecting a sample design for a national study of care for an uncommon disease, and the adaptations, opportunities and costs associated with the choice of national probability sampling in a study of HIV/AIDS. SETTING A consortium of public and private funders, research organizations, community advocates, and local providers assembled to design and execute the study. DESIGN Data collected by providers or collected for administrative purposes are limited by selectivity and concerns about validity. In studies based on convenience sampling, generalizability is uncertain. Multistage probability sampling through households may not produce sufficient cases of diseases that are not highly prevalent. In such cases, an attractive alternative design is multistage probability sampling through sites of care, in which all persons in the reference population have some chance of random selection through their medical providers, and in which included subjects are selected with known probability. DATA COLLECTION AND PRINCIPAL FINDINGS: Multistage national probability sampling through providers supplies uniquely valuable information, but will not represent populations not receiving medical care and may not provide sufficient cases in subpopulations of interest. Factors contributing to the substantial cost of such a design include the need to develop a sampling frame, the problems associated with recruitment of providers and subjects through medical providers, the need for buy-in from persons affected by the disease and their medical practitioners, as well as the need for a high participation rate. Broad representation from the national community of scholars with relevant expertise is desirable. Special problems are associated with organization of the research effort, with instrument development, and with data analysis and dissemination in such a consortium. CONCLUSIONS Multistage probability sampling through providers can provide unbiased, nationally representative data on persons receiving regular medical care for uncommon diseases and can improve our ability to accurately study care and its outcomes for diseases such as HIV/AIDS. However, substantial costs and special circumstances are associated with the implementation of such efforts.

Abstract
BACKGROUND AND METHODS In order to elucidate the medical care of patients with human immunodeficiency virus (HIV) infection in the United States, we randomly sampled HIV-infected adults receiving medical care in the contiguous United States at a facility other than military, prison, or emergency department facility during the first two months of 1996. We interviewed 76 percent of 4042 patients selected from among the patients receiving care from 145 providers in 28 metropolitan areas and 51 providers in 25 rural areas. RESULTS During the first two months of 1996, an estimated 231,400 HIV-infected adults (95 percent confidence interval, 162,800 to 300,000) received care. Fifty-nine percent had the acquired immunodeficiency syndrome according to the case definition of the Centers for Disease Control and Prevention, and 91 percent had CD4+ cell counts of less than 500 per cubic millimeter. Eleven percent were 50 years of age or older, 23 percent were women, 33 percent were black, and 49 percent were men who had had sex with men. Forty-six percent had incomes of less than $10,000 per year, 68 percent had public health insurance or no insurance, and 30 percent received care at teaching institutions. The estimated annual direct expenditures for the care of the patients seen during the first two months of 1996 were $5.1 billion; the expenditures for the estimated 335,000 HIV-infected adults seen at least as often as every six months were $6.7 billion, which is about $20,000 per patient per year. CONCLUSIONS In this national survey we found that most HIV-infected adults who were receiving medical care had advanced disease. The patient population was disproportionately male, black, and poor. Many Americans with diagnosed or undiagnosed HIV infection are not receiving medical care at least as often as every six months. The total cost of medical care for HIV-infected Americans accounts for less than 1 percent of all direct personal health expenditures in the United States.
