Use of mental health and substance abuse treatment services among adults with HIV in the United States

BACKGROUND

The need for mental health and substance abuse services is great among those with human immunodeficiency virus (HIV), but little information is available on services used by this population or on individual factors associated with access to care.

METHODS

Data are from the HIV Cost and Services Utilization Study, a national probability survey of 2864 HIV-infected adults receiving medical care in the United States in 1996. We estimated 6-month use of services for mental health and substance abuse problems and examined socioeconomic, HIV illness, and regional factors associated with use.

RESULTS

We estimated that 61.4% of 231 400 adults under care for HIV used mental health or substance abuse services: 1.8% had hospitalizations, 3.4% received residential substance abuse treatment, 26.0% made individual mental health specialty visits, 15.2% had group mental health treatment, 40.3% discussed emotional problems with medical providers, 29.6% took psychotherapeutic medications, 5.6% received outpatient substance abuse treatment, and 12.4% participated in substance abuse self-help groups. Socioeconomic factors commonly associated with poorer access to health services predicted lower likelihood of using mental health outpatient care, but greater likelihood of receiving substance abuse treatment services. Those with less severe HIV illness were less likely to access services. Persons living in the Northeast were more likely to receive services.

CONCLUSIONS

The magnitude of mental health and substance abuse care provided to those with known HIV infection is substantial, and challenges to providers should be recognized. Inequalities in access to care are evident, but differ among general medical, specialty mental health, and substance abuse treatment sectors.

Circumstances at HIV diagnosis and progression of disease in older HIV-infected Americans

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.

Relationship between having a home doctor and outpatient utilization

While universal insurance coverage should eliminate or substantially reduce financial and certain structural barriers to medical care, inequity in utilization of care may continue to exist. We conducted a questionnaire survey of a national random sample of 4500 Japanese age 16 or over in October, 1995. Separate analyses were conducted to predict the physician visit rates for the entire respondents (N=3395) and for those with chronic conditions (N=777). Forty-three percent of the total subjects reported an ambulatory physician visit within the past three months. About 17% of subjects with one chronic condition and 14% of those with two or more chronic conditions did not have any physician visits within recent three months. The regression model demonstrated that having a home doctor, as well as comorbidity and perceived health status, is significantly associated with outpatient visit both among all subjects (p < 0.0001) and among those with chronic conditions (p < 0.01). The Japanese health system still has unevenness in outpatient resource utilization. This mainly pertains to whether they have their own regular physician. The failure of some persons with chronic diseases to be seen requires further investigation.

End-of-life discussions and preferences among persons with HIV

CONTEXT

Deficits in advance care planning leave many patients and their physicians unprepared for decisions about end-of-life care. Even though the prognosis has improved for many persons with human immunodeficiency virus (HIV) infection, a need for planning remains.

OBJECTIVE

To evaluate prevalence of end-of-life discussions, use of advance directives, and preferences concerning end-of-life care and their relationship with patient demographics, clinical status, psychosocial variables, and practitioner characteristics among HIV-infected persons.

DESIGN, SETTING, AND PATIENTS

Cross-sectional survey of a US probability sample of 2864, which represents 231 400 adults receiving care for HIV, conducted from January 1996 to April 1997.

MAIN OUTCOME MEASURES

Communication with physician regarding end-of-life issues, completion of an advance directive, preference for aggressiveness of care, and willingness to tolerate future permanent adverse health states.

RESULTS

A total of 1432 patients (50%) discussed some aspect of end-of-life care with their practitioner and 1088 (38%) completed an advance directive. Patients were more likely to complete an advance directive after a physician discussion (odds ratio [OR], 5.82; 95% confidence interval [CI], 4.50-7.52). Practitioners discussed end-of-life care less with blacks (OR, 0.57; 95% CI, 0.39-0.83) and Latinos (OR, 0.74; 95% CI, 0.55-0.98) than with whites. Women (OR, 1.39; 95% CI, 1.05-1.84) and patients with children in the household (OR, 1.53; 95% CI, 1.12-2.10) communicated the most with practitioners about end-of-life issues. Patients infected with HIV via injection drug use (OR, 0.64; 95% CI, 0.45-0.89) and those with less education communicated the least with physicians about end-of-life issues. Less denial, greater trust in one's practitioner, and longer patient-practitioner relationship were associated with more advance care planning.

CONCLUSIONS

Half of all persons infected with HIV are at risk of making end-of-life decisions without prior discussions with their health care practitioners. Blacks, Latinos, intravenous drug users, and less educated individuals need advance care planning interventions in clinical HIV programs.

Associations of symptoms and health-related quality of life: findings from a national study of persons with HIV infection

BACKGROUND

Health-related quality of life refers to how well people are able to perform daily activities (functioning) and how they feel about their lives (well-being). The relationship between symptoms and health-related quality of life has not been fully explored.

OBJECTIVE

To estimate the association of HIV symptoms with health-related quality of life and with disability days.

DESIGN

Prospective cohort study.

SETTING

HIV providers in 28 urban and 24 rural randomly selected sites throughout the United States.

PATIENTS

Nationally representative sample of 2267 adults with known HIV infection who were interviewed in 1996 and again between 1997 and 1998.

MEASUREMENTS

Symptoms, two single-item global measures of health-related quality of life (perceived health and perceived quality of life), and disability days.

RESULTS

White patches in the mouth; nausea or loss of appetite; persistent cough, difficulty breathing, or difficulty catching one's breath; and weight loss were associated with more disability days and worse scores on both health-related quality-of-life measures. Headache; pain in the mouth, lips, or gums; dry mouth; and sinus infection, pain, or discharge were associated with worse perceived health. Pain in the mouth, lips, or gums; trouble with eyes; pain, numbness, or tingling of hands or feet; and diarrhea or loose or watery stools were associated with worse perceived quality of life. Headache and fever, sweats, or chills were associated with more disability days.

CONCLUSIONS

Several symptoms are associated with worse health-related quality of life and more disability days in persons with HIV infection. In such patients, targeting specific symptoms may improve health-related quality of life and reduce disability.

Expenditures for the care of HIV-infected patients in the era of highly active antiretroviral therapy

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.

The impact of state policy on the costs of HIV infection

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.

Use of unpaid and paid home care services among people with HIV infection in the USA

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.

Propensity of HIV patients to seek urgent and emergent care. HIV Cost and Services Utilization Study Consortium

OBJECTIVE

To assess the propensity of HIV-infected adults to seek care for common symptoms, and to determine whether they would seek care in the emergency department (ED) or with their primary care provider.

DESIGN

Cross-sectional interview study.

SETTING

Patients in care in the 48 contiguous United States.

PARTICIPANTS

A nationally representative group of HIV- infected adults selected using multistage probability sampling.

MEASUREMENTS

Subjects were interviewed between January 1996 and April 1997. Patients with advanced disease (past AIDS diagnosis and/or CD4 cell count <200/microL) and early disease were asked how they would seek care for key HIV-associated symptom complexes. Three advanced disease and 3 early disease symptom scenarios were used.

MAIN RESULTS

Most advanced disease patients (78% to 87%) would seek care right away from the ED or primary care provider for the symptoms asked. Most early disease patients (82%) would seek care right away for new respiratory symptoms; fewer would do so for headache (46%) or oral white patches (62%). In a multivariate model, independent predictors of propensity to use the ED for advanced disease symptoms included African-American ethnicity (adjusted odds ratio [OR], 2.5; 95% confidence interval [95% CI], 1.8 to 3.4); less education (adjusted OR, 1.4; 95% CI, 1.1 to 1.7); drug dependence (adjusted OR, 1.4; 95% CI, 1.1 to 1.7); annual income less than $5,000 (adjusted OR, 1.5; 95% CI, 1.0 to 2.3); and lower psychological well-being (adjusted OR, 0.9; 95% CI, 0.9 to 1.0). In early disease, the following independently predicted ED use: African American (adjusted OR, 4.7; 95% CI, 3.1 to 7.1) or Hispanic ethnicity (adjusted OR 2.4; 95% CI, 1.4 to 4.3), female gender (adjusted OR, 1.6; 95% CI, 1.2 to 2.2), annual income less than $5,000 (adjusted OR, 1.8; 95% CI, 1.1 to 3. 0), and lower psychological well-being (adjusted OR, 0.9; 95% CI, 0. 8 to 1.0).

CONCLUSIONS

Many patients would use the ED instead of same-day primary care for several common symptoms of HIV disease. African Americans, the poor, and patients with psychological symptoms had a higher propensity to use the ED.

Physical and role functioning among persons with HIV: results from a nationally representative survey

BACKGROUND

Functional limitations of persons living with HIV affect their care needs and ability to perform social roles such as employment. Earlier estimates are outdated, and nationally representative estimates of prevalence and distribution of these limitations have not previously been available.

OBJECTIVES

The objectives of this study were to characterize physical and role limitations experienced by adults in care for HIV disease in the United States and to analyze variations by demographic and health characteristics in a multivariate framework.

METHODS

Among 2,836 respondents in the HIV Cost and Services Utilization Survey, we assessed physical functioning with a 9-item scale designed to span a broad continuum of tasks and administered the 2-item ACTG SF-21 role functioning scale. Linearization methods were used to account for the multistage survey design.

RESULTS

Limitation in complex roles-working at a job, working around the house, or going to school-was more prevalent than limitation in most specific physical tasks. Among physical tasks, limitation was more prevalent in energy-demanding activities such as climbing stairs (43%) or walking >1 block (26%) than in self-care tasks such as bathing and dressing (14%). Greater limitation was associated with older age, lower educational attainment, more advanced disease, and higher symptom burden. Protease inhibitor treatment was associated with somewhat less physical limitation but no difference in role limitation.

CONCLUSIONS

Functional status varied widely, suggesting the need for flexible, individualized care system responses. Results identified subgroups whose needs warrant special attention. Symptom intensity, pain, and fatigue were strongly associated with limitation; improved management of these disease manifestations might improve physical and social functioning.

Management of multiple sclerosis across managed care and fee-for-service systems

OBJECTIVE

To measure and compare care for adults with MS across managed care and fee-for-service (FFS) health systems.

METHODS

The authors sampled adults with MS having physician visits over a 2-year period from a group model health maintenance organization (HMO) in southern California, from a midwestern independent practice association (IPA) model managed care plan, and from the FFS portion of the practices of a random sample of southern California neurologists. The authors mailed surveys to subjects in mid-1996; 930 of 1,164 (80%) of those eligible responded. The authors measured sociodemographic and clinical characteristics, management of recent changes in mobility, bladder control, and fatigue, use of a disease-modifying agent, assessment of general health symptoms and issues, and unmet information needs. The authors adjusted comparisons between systems for comorbidity, disease severity, and disease type.

RESULTS

The groups differed on most sociodemographic and clinical characteristics. There were few differences in symptom management; differences that did exist tended toward more referrals or treatment for the FFS group. Access to the disease-modifying agent available at the time of the survey did not differ across systems, although patients' perceptions of the rationale for not using the drug did vary. General health issues and symptoms were more often assessed in the FFS and IPA systems than in the HMO, but improvement was needed across all three systems of care. There were substantial unmet information needs in all groups and especially high ones in the FFS and HMO samples.

CONCLUSIONS

Strategies to improve care for people with MS should be developed and evaluated, particularly in areas like symptom assessment and meeting patient information needs. Where variations in service delivery exist, longitudinal studies are also needed to evaluate the potential impact on outcomes and to evaluate reasons for variation.

Prevalence and predictors of highly active antiretroviral therapy use in patients with HIV infection in the united states. HCSUS Consortium. HIV Cost and Services Utilization

BACKGROUND

Highly active antiretroviral therapy (HAART) became standard for HIV in 1996. Studies at that time showed that most people infected with HIV had initiated HAART, but that members of minority groups and poor people had lower HAART use. It is not known whether high levels of HAART use have been sustained or whether socioeconomic and racial disparities have diminished over time.

OBJECTIVES

To determine the proportion of patients who had received and were receiving HAART by January 1998, and to evaluate predictors of HAART receipt.

DESIGN AND PARTICIPANTS

Prospective cohort study of a national probability sample of 2267 adults receiving HIV care who completed baseline, first follow-up, and second follow-up interviews from January 1996 to January 1998.

MAIN OUTCOME VARIABLES

Proportion currently using HAART at second follow-up (August 1997 to January 1998), contrasted with the cumulative proportions using HAART at any time before January 1998 and before December 1996.

ANALYSES

Bivariate and multiple logistic regression analysis of population characteristics predicting current use of HAART at the time of the second follow-up interview.

RESULTS

The proportion of patients ever having received HAART increased from 37% in December 1996 to 71% by January 1998, but only 53% of people were receiving HAART at the time of the second follow-up interview. Differences between sociodemographic groups in ever using HAART narrowed after 1996. In bivariate analysis, several groups remained significantly less likely to be using HAART at the time of the second follow-up interview: blacks, male and female drug users, female heterosexuals, people with less education, those uninsured and insured by Medicaid, those in the Northeast, and those with CD4 counts of >/=500 cells/microl (all p <.05). Using multiple logistic regression analysis, low CD4 count (for CD4 <50 cells/microl: odds ratio [OR], 3.20; p <.001) remained a significant predictor of current HAART use at the time of the second follow-up interview, but lack of insurance (OR, 0.71; p <.05) predicted not receiving HAART.

CONCLUSIONS

The proportion of persons under HIV care in the United States who had ever received HAART increased to over 70% of the affected population by January 1998 and the disparities in use between groups narrowed but did not disappear. However, nearly half of those eligible for HAART according to the U.S. Department of Health and Human Services guidelines were not actually receiving it nearly 2 years after these medications were first introduced. Strategies to promote the initiation and continuation of HAART are needed for those without contraindications and those who can tolerate it.

Delayed medical care after diagnosis in a US national probability sample of persons infected with human immunodeficiency virus

OBJECTIVE

To identify health care and patient factors associated with delayed initial medical care for human immunodeficiency virus (HIV) infection.

DESIGN

Survey of a national probability sample of persons with HIV in care.

SETTING

Medical practices in the contiguous United States.

PATIENTS

Cohort A (N = 1540) was diagnosed by February 1993 and was in care within 3 years; cohort B (N = 1960) was diagnosed by February 1995 and was in care within 1 year of diagnosis.

MAIN OUTCOME MEASURE

More than 3- or 6-month delay.

RESULTS

Delay of more than 3 months occurred for 29% of cohort A (median, 1 year) and 17% of cohort B. Having a usual source of care at diagnosis reduced delay, with adjusted odds ratios (ORs) of 0.61 (95% confidence interval [CI], 0.48-0.77) in cohort A and 0. 70 (95% CI, 0.50-0.99) in cohort B. Medicaid coverage at diagnosis showed lower adjusted ORs of delay compared with private insurance (cohort A: adjusted OR, 0.52; 95% CI, 0.30-0.92; cohort B: adjusted OR, 0.48; 95% CI, 0.27-0.85). Compared with whites, Latinos had 53% and 95% higher adjusted ORs of delay (P<.05) in cohorts A and B, respectively, and African Americans had a higher adjusted OR in cohort A (1.56; 95% CI, 1.19-2.04). The health care factors showed similar effects on delay of greater than 6 months.

CONCLUSIONS

Medicaid insurance and a usual source of care were protective against delay after HIV diagnosis. After full adjustment, delay was still greater for Latinos and, to a lesser extent, African Americans compared with whites.

Care of vaginal symptoms among HIV-infected women

OBJECTIVE

Gynecologic disease is common in HIV-infected women. We examine the sociodemographic, clinical, and provider factors associated with the care of women with vaginal symptoms.

METHODS

Women enrolled in the HIV Cost and Services Utilization Study (HCSUS), a nationally representative probability sample of HIV-infected adults, were interviewed between January 1996 and April 1997. Women with vaginal symptoms who sought medical attention were asked, "Did your health care provider examine your vaginal area?" Women were also asked if they received medication for their symptoms.

RESULTS

Among 154 women with vaginal symptoms, 127 sought care for their symptoms. Of those who sought care, 48% saw a gynecologist and 52% sought care from nongynecologists, most often their usual HIV care provider. Women who saw a gynecologist for their symptoms were more likely to have received a pelvic examination (92% versus 76%; p =.06) and vaginal fluid collection (98% versus 88%; p =.06) than those who saw their regular HIV provider. Fifteen percent of women received medication for their symptoms without having a pelvic examination; gynecologists were less likely to prescribe without an examination (8% versus 21%; p =.12).

CONCLUSION

Gynecologists are more likely to provide adequate care of vaginal symptoms among HIV-infected women than nongynecologists who were HIV care providers. This specialty difference is consistent with quality of care studies for other medical conditions, but the potential gynecologic complications of inadequate evaluation and treatment warrants further investigation.

Coping, conflictual social interactions, social support, and mood among HIV-infected persons. HCSUS Consortium

This study considers the interrelationships among coping, conflictual social interactions, and social support, as well as their combined associations with positive and negative mood. Research has shown that each of these variables affects adjustment to stressful circumstances. Few studies, however, examine this full set of variables simultaneously. One hundred forty HIV-infected persons completed a questionnaire containing measures of coping, social support, conflictual social interactions, and positive and negative mood. Factor analyses showed that perceived social support and conflictual social interactions formed separate factors and were not strongly related. Compared to perceived social support, social conflict was more strongly related to coping behaviors, especially to social isolation, anger, and wishful thinking. Conflictual social interactions were more strongly related to negative mood than was perceived social support. Coping by withdrawing socially was significantly related to less positive and greater negative mood. The findings point to the importance of simultaneously considering coping, supportive relationships, and conflictual relationships in studies of adjustment to chronic illness. In particular, a dynamic may occur in which conflictual social interactions and social isolation aggravate each other and result in escalating psychological distress.

National estimates of HIV-related symptom prevalence from the HIV Cost and Services Utilization Study

OBJECTIVES

The objectives of this study were (1) to estimate the prevalence, bothersomeness, and variation of HIV-related symptoms in a nationally representative sample of HIV-infected adults receiving medical care and (2) to evaluate new aggregate measures of symptom frequency and bothersomeness.

METHODS

Beginning in January 1996, 76% of a multistage national probability sample of 4,042 HIV-infected adults receiving medical care were interviewed. Participants endorsed the presence and degree of bothersomeness of 14 HIV-related symptoms during the preceding 6 months. Sex-standardized symptom number and bothersomeness indices were constructed. After sampling weights were incorporated, symptom distributions were compared according to selected characteristics by analysis of variance and multiple linear regression modeling.

RESULTS

Prevalence of specific symptoms in the reference population was as follows: fever/night sweats, 51.1%; diarrhea, 51%; nausea/anorexia, 49.8%; dysesthesias, 48.9%; severe headache, 39.3%; weight loss, 37.1%; vaginal symptoms, 35.6% of women; sinus symptoms, 34.8%; eye trouble, 32.4%; cough/dyspnea, 30.4%; thrush, 27.3%; rash, 24.3%; oral pain, 24.1%; and Kaposi's sarcoma, 4%. Aggregate measures were reliable (Cronbach's alpha > or =0.75) and demonstrated construct validity when compared with other measures of disease severity. After adjustment for CD4 count, both symptom number and bothersomeness varied significantly (P <0.05) by teaching status of care setting, exposure/risk group, educational achievement, sex, annual income, employment, and insurance category. However, the magnitude of variation was small. Symptoms were greatest in women and injection drug users, as well as in persons with lower educational levels, lower income, and Medicare enrollment or those who were followed up at teaching hospitals.

CONCLUSIONS

The prevalence and bothersomeness of HIV-related symptoms are substantial and vary by setting of care and patient characteristics.

Perceived unmet need for oral treatment among a national population of HIV-positive medical patients: social and clinical correlates

OBJECTIVES

This study examines social, behavioral, and clinical correlates of perceived unmet need for oral health care for people with HIV infection.

METHODS

Baseline in-person interviews with 2864 individuals were conducted with the HIV Cost and Services Utilization Study cohort, a nationally representative probability sample of HIV-infected persons in medical care. Bivariate and logistic regression analyses were conducted, with unmet need in the last 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables.

RESULTS

We estimate that 19.3% of HIV-infected medical patients (n = 44,550) had a perceived unmet need for dental care in the last 6 months. The odds of having unmet dental needs were highest for those on Medicaid in states without dental benefits (odds ratio [OR] = 2.21), for others with no dental insurance (OR = 2.26), for those with incomes under $5000 (OR = 2.20), and for those with less than a high school education (OR = 1.83). Low CD4 count was not significant.

CONCLUSIONS

Perceived unmet need was related more to social and economic factors than to stage of infection. An expansion of dental benefits for those on Medicaid might reduce unmet need for dental care.

HIV-infected parents and their children in the United States

OBJECTIVES

This study sought to determine the number, characteristics, and living situations of children of HIV-infected adults.

METHODS

Interviews were conducted in 1996 and early 1997 with a nationally representative probability sample of 2864 adults receiving health care for HIV within the contiguous United States.

RESULTS

Twenty-eight percent of infected adults in care had children. Women were more likely than men to have children (60% vs 18%) and to live with them (76% vs 34%). Twenty-one percent of parents had been hospitalized during the previous 6 months, and 10% had probably been drug dependent in the previous year. Parents continued to have children after being diagnosed with HIV: 12% of all women conceived and bore their youngest child after diagnosis, and another 10% conceived before but gave birth after diagnosis.

CONCLUSIONS

Clinical and support services for people affected by the HIV epidemic should have a family focus.

Delays in seeking HIV care due to competing caregiver responsibilities

OBJECTIVES

This study sought to describe the characteristics of HIV-infected persons who delay medical care for themselves because they are caring for others.

METHODS

HIV-infected adults (n = 2864) enrolled in the HIV Cost and Services Utilization Study (1996-1997) were interviewed.

RESULTS

The odds were 1.6 times greater for women than for men to put off care (95% confidence interval [CI] = 1.2, 2.2); persons without insurance and with CD4 cell counts above 500 were also significantly more likely to put off care. Having a child in the household was associated with putting off care (odds ratio [OR] = 1.8, 95% CI = 1.4, 2.3).

CONCLUSIONS

Women or individuals with a child in the household should be offered services that might allow them to avoid delays in seeking their own medical care.

Health-related quality of life in patients with human immunodeficiency virus infection in the United States: results from the HIV Cost and Services Utilization Study

PURPOSE

To measure health-related quality of life among adult patients with human immunodeficiency virus (HIV) disease; to compare the health-related quality of life of adults with HIV with that of the general population and with patients with other chronic conditions; and to determine the associations of demographic variables and disease severity with health-related quality of life.

SUBJECTS AND METHODS

We studied 2,864 HIV-infected adults participating in the HIV Cost and Services Utilization Study, a probability sample of adults with HIV receiving health care in the contiguous United States (excluding military hospitals, prisons, or emergency rooms). A battery of 28 items covering eight domains of health (physical functioning, emotional well-being, role functioning, pain, general health perceptions, social functioning, energy, disability days) was administered. The eight domains were combined into physical and mental health summary scores. SF-36 physical functioning and emotional well-being scales were compared with the US general population and patients with other chronic diseases on a 0 to 100 scale.

RESULTS

Physical functioning was about the same for adults with asymptomatic HIV disease as for the US population [mean (+/- SD) of 92+/-16 versus 90+/-17) but was much worse for those with symptomatic HIV disease (76+/-28) or who met criteria for the acquired immunodeficiency syndrome (AIDS; 58+/-31). Patients with AIDS had worse physical functioning than those with other chronic diseases (epilepsy, gastroesophageal reflux disease, clinically localized prostate cancer, clinical depression, diabetes) for which comparable data were available. Emotional well-being was comparable among patients with various stages of HIV disease (asymptomatic, 62+/-9; symptomatic, 59+/-11; AIDS, 59+/-11), but was significantly worse than the general population and patients with other chronic diseases except depression. In multivariate analyses, HIV-related symptoms were strongly associated with physical and mental health, whereas race, sex, health insurance status, disease stage, and CD4 count were at most weakly associated with physical and mental health.

CONCLUSIONS

There is substantial morbidity associated with HIV disease in adults. The variability in health-related quality of life according to disease progression is relevant for health policy and allocation of resources, and merits the attention of clinicians who treat patients with HIV disease.

Use of dental care by HIV-infected medical patients

Although increasing attention has been paid to the use of dental care by HIV patients, the existing studies do not use probability samples, and no accurate population estimates of use can be made from this work. The intent of the present study was to establish accurate population estimates of the use of dental services by patients under medical care. The study, part of the HIV Cost and Services Utilization Study (HCSUS), created a representative national probability sample, the first of its kind, of HIV-infected adults in medical care. Both bivariate and logistic regressions were conducted, with use of dental care in the preceding 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables. Forty-two percent of the sample had seen a dental health professional in the preceding 6 months. The bivariate logits for use of dental care show that African-Americans, those whose exposure to HIV was caused by hemophilia or blood transfusions, persons with less education, and those who were employed were less likely to use dental care (p < 0.05). Sixty-five percent of those with a usual source of care had used dental care in the preceding 6 months. Use was greatest among those obtaining dental care from an AIDS clinic (74%) and lowest among those without a usual source of dental care (12%). We conclude that, in spite of the high rate of oral disease in persons with HIV, many do not use dental care regularly, and that use varies by patient characteristics and availability of a regular source of dental care.

Health insurance and access to care for symptomatic conditions

BACKGROUND

The uninsured receive less medical care than the insured. However, it is not known whether the uninsured are less likely to seek medical care for highly "serious" or "morbid" symptoms.

METHODS

Participants in the National Access to Care Survey were asked whether they had experienced any of 15 highly serious or morbid symptoms. Those who did were asked whether they received medical care and, if care was not received, whether care was thought to have been necessary.

RESULTS

A total of 574 respondents (16.4%) reported 794 new serious or morbid symptoms. Of these, 499 people (86.9%) had health insurance, and they reported 691 new symptoms; 75 (13.1%) lacked health insurance, and they reported 103 symptoms. The uninsured were less likely to have received medical care and more likely to say they did not receive care even though they thought it was needed (P = .001). Medical care was received for 45.4% of symptoms for the insured and 24.3% for the uninsured; care was not thought to have been needed for 41.0% of symptoms for the insured and 45.6% for the uninsured; and care was thought necessary but was not received for 13.6% of symptoms for the insured and 30.1% for the uninsured. In multivariate analysis, the uninsured were much less likely to have received care than the insured (adjusted odds ratio, 0.43; 95% confidence interval, 0.23-0.81).

CONCLUSION

Lack of health insurance is a major barrier to receiving medical care, even for highly serious and morbid symptoms.

Ethnic and racial differences in long-term survival from hospitalization for HIV infection

This prospective cohort study compares 200 hospitalized, HIV-infected patients (Hispanic, African American, and white) from May 1992 to October 1998 to assess mortality (versus survival) over 75 months of follow-up. The relative risk of six-year mortality for each ethnic group is compared using Cox proportional hazards models after controlling for sociodemographic and clinical characteristics, access to general medical care, and HIV-specific treatment. The median survival of Hispanics (15.5 months) was significantly (p < 0.05) shorter than that of whites (23.8); survival for African Americans (35.1) did not differ from whites. In multivariate analysis, the adjusted relative risk of six-year mortality for Hispanics compared with whites was 2.14 (95 percent confidence interval = 1.26-3.66). The poor outcomes of Hispanics was not explained by access to general care or by HIV-specific treatment.

Impact of psychiatric conditions on health-related quality of life in persons with HIV infection

OBJECTIVE

Little is known about the impact of comorbid psychiatric symptoms in persons with HIV. This study estimates the burden on health-related quality of life associated with comorbid psychiatric conditions in a nationally representative sample of persons with HIV.

METHOD

The authors conducted a multistage sampling of urban and rural areas to produce a national probability sample of persons with HIV receiving medical care in the contiguous United States (N=2,864). Subjects were screened for psychiatric conditions with the short form of the Composite International Diagnostic Interview. Heavy drinking was assessed on the basis of quantity and frequency of drinking. Health-related quality of life was rated with a 28-item instrument adapted from similar measures used in the Medical Outcomes Study.

RESULTS

HIV subjects with a probable mood disorder diagnosis had significantly lower scores on health-related quality of life measures than did those without such symptoms. Diminished health-related quality of life was not associated with heavy drinking, and in drug users it was accounted for by presence of a comorbid mood disorder.

CONCLUSIONS

Optimization of health-related quality of life is particularly important now that HIV is a chronic disease with the prospect of long-term survival. Comorbid psychiatric conditions may serve as markers for impaired functioning and well-being in persons with HIV. Inclusion of sufficient numbers of appropriately trained mental health professionals to identify and treat such conditions may reduce unnecessary utilization of other health services and improve health-related quality of life in persons with HIV infection.
