Abstract
The authors' review of the health services literature since the release of the landmark Report of the Secretary's Task Force Report of Black and Minority Health in 1985 revealed significant differences in access to medical care by race and ethnicity within certain disease categories and types of health services. The differences are not explained by such factors as socioeconomic status (SES), insurance coverage, stage or severity of disease, comorbidities, type and availability of health care services, and patient preferences. Under certain circumstances when important variables are controlled, racial and ethnic disparities in access are reduced and may disappear. Nonetheless, the literature shows that racial and ethnic disparities persist in significant measure for several disease categories and service types. The complex challenge facing current and future researchers is to understand the basis for such disparities and to determine why disparities are apparent in some but not other disease categories and service types.

Abstract
Antiretroviral therapy (ART) use was examined in a cohort of homosexual men infected with HIV-1 for long periods. Multivariate logistic regression models, stratified by clinical indication (below and above 500 CD4 cells/microl or prior AIDS), were used to determine predictors of ART naivete. Of the 673 men seen at visit 28 (10/97-4/98), 89 (13.2%) never used ART and 548 (81.4%) were current users; 55% of the therapy-naive were ART eligible. Lower CD4 cell counts predicted (P <.001) ART use. Determinants of therapy naivete differed by clinical indication. African-American race and no prior ambulatory visit predicted (P <.05) ART naivete in men with > or =500 CD4 cells/microl. Among those with clinical indications, less education, younger age, multiple sexual partners, and no prior ambulatory visit significantly predicted ART naivete. In this era of effective ART, use was not universal. Besides disease markers, these nonclinical determinants need to be considered for promoting population therapy effectiveness.

Abstract
OBJECTIVE To evaluate the accordance between three measures of self-reported medication adherence. METHODS A survey was administered to HIV patients. The three adherence measures included a four-item Morisky-type scale (Measure1) and two measures defining adherence as the percentage of doses taken as prescribed during the past two days (Measure2) or past two weeks (Measure3). RESULTS For Measure1, 29.2% of the patients were categorized as high adherence and 61.5% as medium adherence. For Measure2 and Measure3, the mean scores were 93.6% and 96.5%, respectively. Using 90% as cutoff values, 78.5% and 95.4% of the patients were classified as adherent by Measure2 and Measure3, respectively (kappa = 0.30; p = 0.001). When 80% was used, 90.8% of the patients were classified as adherent for Measure2 and 96.9% for Measure3 (kappa = 0.48; p < 0.001). When using 90% and 80% as cutoff values to categorize Measure2 and Measure3 as three levels, there was no agreement between Measure1 and the other two measures. The accordance of Measure2 and Measure3 was significant albeit not high (kappa = 0.31; p < 0.001). CONCLUSIONS The accordance between a Morisky-type adherence scale and measures of missed doses is unsatisfactory. However, "missed-dose" measures using two-day or two-week time periods yield fairly similar results. Researchers should be cautious when comparing adherence rates between studies that use different methods for assessing adherence.

Abstract
The authors assessed temporal trends in acquired immunodeficiency syndrome (AIDS) survival for 15,271 persons in San Francisco, California, diagnosed between 1987 and 1996 with an opportunistic illness included in the 1987 AIDS case definition. Predictors of survival were evaluated for 5,686 persons who were diagnosed between 1993 and 1996 and met the 1993 AIDS case definition. Median survival was 19 months for persons diagnosed between 1987 and 1989, 17 months for persons diagnosed between 1990 and 1992, 15 months for persons diagnosed between 1993 and 1994, and 31 months for persons diagnosed between 1995 and 1996. Decreased mortality was associated with use of antiretroviral therapy without protease inhibitors before AIDS (relative hazard (RH) = 0.88, 95% confidence interval (CI): 0.8, 1.0) and after AIDS (RH = 0.83, 95% CI: 0.7, 0.9) and use of antiretroviral agents with protease inhibitors before AIDS (RH = 0.25, 95% CI: 0.2, 0.3) and after AIDS (RH = 0.36, 95% CI: 0.3, 0.4). Increased mortality was found for persons aged > or = 40 years (RH = 1.43, 95% CI: 1.3, 1.6), persons initially diagnosed with an opportunistic illness (RH = 1.97, 95% CI: 1.8, 2.2), and homosexual injection drug users (RH = 1.33, 95% CI: 1.2, 1.5). Survival after AIDS has increased. Treatment with antiretroviral agents, particularly protease inhibitors, strongly predicts improved survival.

Abstract
OBJECTIVE To describe trends in prescriptions for antiretroviral therapies and factors associated with prescriptions for highly active antiretroviral therapy (HAART). METHODS Medical records of patients at four HIV clinics in New York City were reviewed every 6 months. For the four 6-month periods 1997 to 1998, we identified patients with a CD4+ nadir <500 cells/microl; sample sizes were 434, 432, 503, and 643, respectively. Trends in HAART prescriptions were tested by logistic regression using robust variance estimates because some patients contributed more than one time period. Associations between HAART prescriptions and patient characteristics were tested by chi2 and multiple logistic regression analysis. RESULTS Patients were predominantly black or Hispanic (89%-90%) and male (66%-68%), and injection drug use was the most prevalent HIV risk (38%-49%). From 1997 to 1998, HAART prescriptions increased from 54% to 89% of antiretroviral prescriptions, and the proportion that included an nonnucleoside reverse transcriptase inhibitors (NNRTI) increased from 3% to 10%. HAART prescriptions were inversely associated with CD4+ nadir group during all time periods, and in the second half of 1998, patients with CD4+ nadir between 50 and 199 cells/microl were as likely to be prescribed HAART as the most immunosuppressed patients (CD4+ nadir <50 cells/microl; 91% versus 92%). HAART prescriptions were associated with clinic, HIV risk, and other patient characteristics in some time periods but not consistently. CONCLUSIONS In these four HIV clinics, prescriptions for HAART increased significantly from 1997 to 1998, leveling off at 89% in the second half of 1998. Increasingly, HAART was prescribed for healthier patients and included an NNRTI.

Abstract
OBJECTIVE The aim of this study was to describe the relationship between sociodemographic characteristics and human immunodeficiency (HIV) status of a cohort of injection drug users (IDUs) on their self-reported health service utilization. DESIGN Interviewer-administered questionnaire. METHODS IDUs who had injected illicit drugs within the previous month were recruited through street outreach. They underwent serology for HIV-1 and questionnaires on demographics, drug using behaviors, housing status, and health service utilization (hospitalization overnight and emergency department visits) in the previous 6 months. Logistic regression analysis was used to identify independent associations with the use of health services. RESULTS Of 1,103 cohort participants, 65% were male, 63% were white, and 23% were HIV positive. Cocaine was the most frequently injected drug used. Almost half (47%) had used health services in the previous 6 months. The following variables were associated independently with health service utilization (adjusted odds ratio; 95% confidence interval): unstable housing, defined as living primarily in a hotel, boarding room, or transition house or on the street in the past 6 months (1.44; 1.11-1.86); female gender (1.45; 1.11-1.89); HIV-positive status (1.43; 1.06-1.92); injection of cocaine (1.50; 1.12-2.02); and primary care I physician visit in past 6 months (1.91; 1.39-2.64). CONCLUSION IDUs with unstable housing were more likely to report emergency department and hospital use, which may be a reflection of their disorganized lifestyle or poorer health status. Further studies are required to assess the effect on the health status and health care use of IDUs of interventions that increase the availability of safe, affordable housing.

Abstract
BACKGROUND Previous studies, especially in North America, have shown that socio-economic factors may influence the prognosis for patients with HIV. This study was performed in order to determine if European or non-European origin influence provision of health-care and survival among HIV patients in Europe. METHODS Fifty HIV clinics in 17 European countries are involved in a European prospective, observational multicentre study. In total, 7230 consecutive patients with HIV attending a routine clinic visit were included in the study. Data on demographics, treatment and laboratory results were collected at time of recruitment into the study and thereafter every 6 months. RESULTS The median CD4+ lymphocyte count at AIDS diagnosis was 60/mm3, and was similar for all ethnic groups (P = 0.87, Kruskall-Wallis test). The median terminal CD4+ lymphocyte count was 17/mm3 and, again, there was no significant difference between continents of origin (P = 0.35, Kruskall-Wallis test). Antiretroviral drugs were initiated at similar median CD4+ lymphocyte counts and there was no statistically significant difference in survival after a diagnosis of AIDS. CONCLUSIONS AIDS was diagnosed at the same level of immunodeficiency independent of European or non-European origin and antiretroviral drugs were provided at similar levels of immunodeficiency. No differences in survival depending on continent of origin was found. In spite of these encouraging findings concerns remain that belonging to an ethnic minority can be an obstacle in getting into contact with treatment facilities and thus benefiting from developments in the management of HIV.

Abstract
OBJECTIVES To identify factors associated with the use of medical services, and to test a model of access to care, among HIV-infected women. METHODS A cross-sectional telephone survey was administered to 213 HIV-infected women. Outcomes were having a primary care provider, and use of primary care and emergency health services. Predictors included characteristics of the population-at-risk and of the health care system. RESULTS Ninety-three percent of respondents had a primary care provider. Linear regression found age >45 years (p = .002), perceiving greater barriers to getting to a clinic (p = .04) and greater benefits from medications (p = .03), lack of problems with appointment times (p = .02), having AIDS (p = .01), shorter appointment waiting times (p = .0003), and greater cost of travel to care (p = .001) were associated with a greater number of primary care visits. Thirty-seven percent missed at least 1 primary care appointment. In logistic regression, lack of insurance (odds ratio [OR] = 2.76), current injection drug use (OR = 2.89) and difficulty remembering appointments (OR = 2.36) were associated with having missed any appointments. CONCLUSIONS Characteristics of the population-at-risk and of the health care system both make important contributions to primary care service use.

Abstract
OBJECTIVES Protease inhibitors have become integral to HIV disease management. This paper examines sociodemographic factors affecting patient use and perceived knowledge of protease inhibitors, and the relationship between protease inhibitor use and perceived health. METHODS 1034 people with HIV disease from a large AIDS services organization completed a mailed self-administered survey that assessed sociodemographics, protease inhibitor use and perceived knowledge, and perceived change in health status over the previous year. Multiple logistic regression was used to determine sociodemographic factors independently associated with protease inhibitor use and perceived knowledge, and perceived overall health status. RESULTS Two thirds (66%) of correspondents included in the sample were currently taking protease inhibitors and 52% reported being very knowledgeable about these medications. Adjusting for sociodemographic factors, those who were currently not taking protease inhibitors were more likely to be African American, non-English speaking, earning <$9600 U.S. annually, or uninsured. Among protease inhibitor users, those who reported less knowledge about the drugs were more likely to be nonwhite, earning <$9600 U.S. annually, and not college educated. Protease inhibitor use was independently associated with perceived improved overall health and having been college educated. CONCLUSIONS Further efforts should be directed toward increasing use and knowledge of protease inhibitors among disadvantaged populations.

Abstract
We evaluated the access to, and the factors associated with, protease inhibitor use among persons with AIDS in Los Angeles County. A population-based sample of adult persons with AIDS is routinely interviewed in Los Angeles County and includes a 30% random sample of men who have sex with men and all other persons reported with AIDS. Since May of 1996, all participants were asked if their physician had ever prescribed a protease inhibitor for their use. The possible association between protease inhibitor use and sociodemographic, temporal and health care factors was assessed for the 12-month period May 1996 through April 1997. Logistic regression was employed for multivariate analysis. Over the 12-month study period, 61.7% (209/339) persons interviewed reported that their physician had prescribed a protease inhibitor as part of their therapy. In bivariate analysis, treatment with protease inhibitor use was more common for whites (71.4%) and US-born Latinos (68.2%) than blacks (53.4%) and foreign-born Latinos (56.6%), among person of higher income (71.2%) than lower (< $10,000) income (50.3%), in those who reported having insurance (66.7%) than those uninsured (47%) and among persons receiving care at private clinics (86.4%) than at HMOs (63.4%) or public clinics (55.2%). An increasing trend of protease inhibitor use with higher educational level and declining CD4+ count was observed. A temporal increase was noted and this trend was most pronounced for persons receiving care at public clinics. In multivariate analysis, persons receiving care at private facilities (adjusted OR = 2.9, 95% CI 1.0, 8.2) and those with higher incomes (adjusted OR = 2.5, 95% CI 1.5, 4.3), were more likely to report that their physician had prescribed a protease inhibitor. The effect of facility type was modified by time. During the first six months of the study period (May 1996-October 1996) persons with AIDS receiving care at public facilities and HMO sites were substantially less likely to report having been offered a protease inhibitor (adjusted OR = 0.13, 95% CI 0.03, 0.58 and adjusted OR = 0.23, 95% CI 0.05, 1.2, respectively). However, no significant facility-specific differences were observed over the last six-month period (November 1997-April 1997) evaluated. Our findings suggest that substantial differences exist in the prescribing and use of protease inhibitors among persons with AIDS in Los Angeles County. Several factors, including facility of HIV care, calendar time, income, education level and level of immunosuppression were independently associated with protease inhibitor use and suggest the existence of important barriers to access. Efforts should be made to identify and remove barriers that will ensure the widest possible access to protease inhibitors for patients with a clinical indication for their use.

Abstract
OBJECTIVE The assessment, in its qualitative dimension, of the utilization--by HIV infected individuals--of selected prescribed drugs during the process of the search for and the obtaining of care in public health services in Belo Horizonte, Brazil. METHODS Fifty two semi-structured interviews with patients, health care workers and non-governamental organizations volunteers were carried out and 1,079 medical records were reviewed. Data were obtained on the utilization of prescribed drugs by HIV infected individuals, whose first visit to one of the public services studied occurred between January 1989 and December 1992. Problems related to the use of anti-retroviral and/or opportunistic infection medication were identified and a qualitative description of their possible causes and consequences was commented on. RESULTS Refusal to use, difficulty in obtaining and in complying with the prescription were the main problems related to anti-retroviral drug use. Causes for such problems included: fear or occurrence of side effects, large number of daily capsules/pills, insufficient and/or irregular distribution of drugs by the public health services and the high cost of anti-retroviral therapy. Based on the reports, the main consequences are likely to be no or late use of anti-retroviral drugs, an increase in resistance and a worsening of the clinical course of the infection. Other problems identified were: self-medication, difficulty in obtaining medications for associated pathologies and in complying with sulfa prescription. CONCLUSION A better understanding of the main obstacles and difficulties experienced by the user of the services, from the moment of the prescription and throughout the treatment, may contribute to an improvement in compliance and the availability and adequate distribution of drugs.

To measure the effect of trimethoprim-sulfamethoxazole (TMP-SMX) in preventing bacterial illness, Pneumocystis carinii pneumonia (PCP), and death in people with AIDS, we conducted a retrospective medical record review of 1078 persons who were observed for 3 years on average who attended nine outpatient facilities in Seattle, Washington between January 1990 and April 1996. We calculated relative risk estimates to measure the protective effect of TMP-SMX on the development of major bacterial illnesses, PCP, and death. Use of TMP-SMX decreased the risk of PCP (relative risk [RR] = 0.23; 95% confidence interval [CI], 0.14-0.36) and deaths not attributable to PCP (RR = 0.59; 95% CI, 0.47-0.73). Prevention of major bacterial illnesses of known etiology was of borderline significance (RR = 0.77; 95% CI, 0.57-1.05) and became statistically significant with the addition of patients with infections of unknown etiology (RR = 0.77; 95% CI 0.61-0.97). Use of TMP-SMX PCP prophylaxis significantly reduced the risks of death and of PCP and was associated with a trend toward reduced risk of major bacterial infections.

Abstract
OBJECTIVE To determine whether race is associated with health insurance coverage and health service use among gay and bisexual men in the Baltimore center of the Multicenter AIDS Cohort Study. METHODS Data from eight semiannual study visits between 1991 and 1996 were used. Descriptive, stratified, and logistic regression analyses were conducted to determine whether race is associated with insurance coverage, medical, or dental service use, after controlling for socioeconomic variables. RESULTS No difference was found between blacks' and whites' likelihood of having health insurance, private insurance, using inpatient, emergency department services, or antiretroviral medications. Whites were more likely to use outpatient services, particularly if CD4 cell counts were high, and were more likely to use dental services, although blacks were more likely to have dental insurance. CONCLUSIONS Further research must be conducted to examine cultural, social, and psychological factors that help explain why white gay men use more outpatient and dental services, when other service use is unrelated to race. Investigators should be precise when using race as a variable in health services and epidemiologic research, emphasizing when racial differences truly exist versus when the variable race is a surrogate for another factor.

Abstract
Between January and May 1994, a 14-question survey regarding oral symptoms and use of dental care services was added to a multistate interview project of adults infected with the human immunodeficiency virus. Results indicate that there are disparities and perceived barriers among HIV-infected adults seeking and receiving dental care. Improved dental care services for all HIV-infected people should include better patient and provider awareness of HIV-related oral conditions, more-affordable treatment and expansion of dental insurance coverage.

Abstract
OBJECTIVE To obtain population-based information on the characteristics of persons who were not receiving chemoprophylaxis against Pneumocystis carinii pneumonia (PCP) by examining the use of primary and secondary PCP prophylaxis among San Francisco residents whose AIDS-defining opportunistic illness was PCP in 1993. DESIGN Retrospective medical record review. SETTING Medical charts were obtained from San Francisco hospitals and outpatient facilities at which AIDS patients received their initial AIDS diagnosis. PARTICIPANTS San Francisco residents whose AIDS-defining opportunistic illness was PCP in 1993. MAIN OUTCOME MEASURES Use of primary and secondary PCP prophylaxis. RESULTS Of the 326 eligible patients, 35% received primary PCP prophylaxis. Non-whites were significantly less likely to have received primary PCP prophylaxis than white patients [22 versus 40%, respectively; odds ratio (OR), 0.49; 95% confidence intervals (CI), 0.28-0.87]. Uninsured individuals-were also less likely to have received primary PCP prophylaxis than those with insurance (18 versus 41%; OR, 0.35; 95% CI, 0.17-0.73). The sociodemographic characteristics of patients who did and did not receive secondary PCP prophylaxis did not differ significantly. The most frequently cited reasons for not receiving primary PCP prophylaxis were that patients were unaware of their infection with HIV or were not receiving regular medical care. CONCLUSIONS Barriers to receipt of PCP prophylaxis exist and are resulting in cases of preventable disease and unnecessary medical costs. Interventions to increase counseling, testing, and referral to medical care for persons at high risk for HIV infection are needed.

Abstract
Many factors, including therapy and behavioral changes, have modified the course of the HIV/AIDS epidemic in recent years. To include these modifications in HIV/AIDS models, in the absence of appropriate external data sources, changes over time in the parameters can be incorporated by a recursive estimation technique such as the Kalman filter. The Kalman filter accounts for stochastic fluctuations in both the model and the data and provides a means to assess any parameter modifications included in new observations. The Kalman filter approach was applied to a simple differential model to describe the observed HIV/AIDS epidemic in the homo/bisexual male community in Paris (France). This approach gave quantitative information on the time-evolution of some parameters of major epidemiological significance (average transmission rate, mean incubation rate, and basic reproduction rate), which appears quite consistent with the recent epidemiological literature.

Abstract
To assess whether better access to community-based outpatient medical services was associated with fewer HIV-related hospitalizations, we studied 217 patients hospitalized at seven southern California hospitals. During hospital admission, patients completed an interview that included one item about the reported difficulty or ease of access to community-based medical services prior to their first hospitalization for HIV-related illness. After discharge, medical records were abstracted for data on prior hospitalizations. CD4 counts, and illness severity. About one-half of patients reported that medical services were readily accessible. Medical records revealed that since the time of HIV infection 49% had two or more total hospitalizations (mean = 2. SD = 2). In multiple logistic regression analysis, better reported access to services was significantly associated with not having been hospitalized (vs. having been hospitalized) over the same time period (OR = 0.73, 95% CI = 0.55-0.97), controlling for CD4 count, illness severity, duration of diagnosed HIV infection, having a regular source of care, type of hospital care, insurance coverage, and other patient characteristics. Improving access to community-based medical services for ambulatory HIV-infected patients may help to avert costly hospital care. Prospective studies are needed to assess whether a causal relationship between greater community-based access and reduced hospitalizations exists and, if so, whether community-based services may be cost-effective substitutes for hospital HIV care.

Abstract
Estimates of the lifetime cost of illnesses are needed for temporal and international comparisons and for assessment of the efficiency of prevention strategies. The goal of the present study was to estimate the average present value, at both the time of diagnosis and the time of seroconversion, of the lifetime cost of health care for HIV infection. Australian data on the monthly cost of HIV-related health care for homosexual men were linked with published data on disease progression using survival analysis methods. Future costs were discounted at 5% per annum. For a patient diagnosed when his CD4+ count fell below 500 x 10(6)/L, the average present value in 1992-1993 of lifetime cost was approximately $93,000, of which 49% was for drugs and 32% was for hospital bed-days. For a man infected in 1992-1993 and diagnosed when his CD4+ count falls below 500 x 10(6)/L, the average present value of lifetime cost at the time of seroconversion is approximately $70,000. These estimates are lower than the lifetime cost of $119,000 reported recently in the United States. However, when the U.S. figure was adjusted to make discounting of future costs consistent between the two studies, lifetime costs were approximately 17% lower in the United States. The lower American costs appear to be due to lower rates of hospitalization and drug prescribing, possibly because of reduced access to health services, but underestimation of costs due to study methodology might also explain the difference.

Abstract
BACKGROUND Previous studies have found that patients with the acquired immunodeficiency syndrome (AIDS) who are admitted to hospitals that admit many such patients have lower mortality rates than patients in hospitals with less experience with AIDS. We examined the relation between physicians' experience with AIDS and the survival of their patients with AIDS. METHODS We studied 403 adult male patients enrolled in a staff-model health maintenance organization in whom first AIDS-defining illnesses were diagnosed from 1984 through mid-1994; we determined that these illnesses met the 1987 case definition of the Centers for Disease Control. We defined three levels of experience for the patients' 125 primary care physicians according to their experience with AIDS during residency training and the cumulative number of patients with AIDS they had cared for in their practices. RESULTS The median survival of the patients of physicians with the least experience in the management of AIDS was 14 months, as compared with 26 months for the patients of physicians with the most experience (P<0.001). Controlling for the severity of illness and the year of diagnosis, we found that the patients cared for by physicians with the most experience had a 31 percent lower risk of death than the patients cared for by physicians with the least experience (P<0.02). Among 244 patients with an AIDS-defining illness diagnosed from 1989 through 1994, after adjustment for the CD4+ cell count and the severity of illness, the risk of death was 44 percent lower for patients of the most experienced physicians than for patients of the least experienced (P<0.02). CONCLUSIONS The experience of primary care physicians in the management of AIDS is significantly associated with survival among their patients.
