    Turner, Barbara J.; Cunningham, William E.; Duan, Naihua; Andersen, Ronald M.; Shapiro, Martin F.; Bozzette, Samuel A.; Nakazono, Terry; Morton, Sally C.; Crystal, Steven; St. Clair, Patti; Stein, Michael; Zierler, Sally (AMA, 2000-09-25)
    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.

    Expenditures for the Care of HIV-Infected Patients in the Era of Highly Active Antiretroviral Therapy
    Bozzette, Samuel A.; Joyce, Geoffrey; McCaffrey, Daniel F.; Leibowitz, Arleen A.; Morton, Sally C.; Berry, Sandra H.; Rastegar, Afshin; Timberlake, David; Shapiro, Martin F.; Goldman, Dana P. (NEJM Group, 2001-03-15)
    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. (N Engl J Med 2001;344:817-23.)

    Psychiatric Disorders and Drug Use Among Human Immunodeficiency Virus–Infected Adults in the United States
    Bing, Eric G.; Burnam, M. Audrey; Longshore, Douglas; Fleishman, John A.; Sherbourne, Cathy Donald; London, Andrew S.; Turner, Barbara J.; Eggan, Ferd; Beckman, Robin; Vitiello, Benedetto; Morton, Sally C.; Orlando, Maria; Bozzette, Samuel A.; Ortiz-Barron, Lucila; Shapiro, Martin F. (AMA, 2001-08)
    Background: There have been no previous nationally representative estimates of the prevalence of mental disorders and drug use among adults receiving care for human immunodeficiency virus (HIV) disease in the United States. It is also not known which clinical and sociodemographic factors are associated with these disorders. Subjects and Methods: We enrolled a nationally representative probability sample of 2864 adults receiving care for HIV in the United States in 1996. Participants were administered a brief structured psychiatric instrument that screened for psychiatric disorders (major depression, dysthymia, generalized anxiety disorders, and panic attacks) and drug use during the previous 12 months. Sociodemographic and clinical factors associated with screening positive for any psychiatric disorder and drug dependence were examined in multivariate logistic regression analyses. Results: Nearly half of the sample screened positive for a psychiatric disorder, nearly 40% reported using an illicit drug other than marijuana, and more than 12% screened positive for drug dependence during the previous 12 months. Factors independently associated with screening positive for a psychiatric disorder included number of HIV-related symptoms, illicit drug use, drug dependence, heavy alcohol use, and being unemployed or disabled. Factors independently associated with screening positive for drug dependence included having many HIV-related symptoms, being younger, being heterosexual, having frequent heavy alcohol use, and screening positive for a psychiatric disorder. Conclusions: Many people infected with HIV may also have psychiatric and/or drug dependence disorders. Clinicians may need to actively identify those at risk and work with policymakers to ensure the availability of appropriate care for these treatable disorders.

    Use of Mental Health and Substance Abuse Treatment Services Among Adults With HIV in the United States
    Burnam, M. Audrey; Bing, Eric G.; Morton, Sally C.; Sherbourne, Cathy Donald; Fleishman, John A.; London, Andrew S.; Vitiello, Benedetto; Stein, Michael; Bozzette, Samuel A.; Shapiro, Martin F. (AMA, 2001-08)
    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.
