Health insurance coverage among persons with AIDS: results from a multistate surveillance project

Determinants of enrolment in health insurance scheme among HIV patients attending a clinic in a tertiary hospital in South-eastern Nigeria

Objective

The study aimed to assess the determinants of enrolment in health insurance schemes among people living with HIV.

Design

The study was a cross-sectional study. A pre-tested interviewer-administered questionnaire was used to collect information from 371 HIV clients attending the clinic. Chi-square statistic was used for bi-variate analysis, and analytical decisions were considered significant at a p-value less than 0.05. Logistic regression was done to determine predictors of enrolment in health insurance.

Setting

The study was carried out in the HIV clinic of Alex Ekwueme Federal University Teaching Hospital Abakaliki, Nigeria.

Participants

HIV clients attending a clinic.

Result

Mean age of respondents was 45.4±10.3, and 51.8% were males. Almost all the respondents were Christians. Only 47.7% were married, and most lived in the urban area. Over 70% had at least secondary education, and only 34.5% were civil servants. About 60% of the respondents were enrolled in a health insurance scheme. Being single (AOR: 0.374, CI:0.204-0.688), being self-employed (AOR: 4.088, CI: 2.315-7.217), having a smaller family size (AOR: 0.124, CI: 0.067-0.228), and having the higher income (AOR: 4.142, CI: 2.07-8.286) were predictors of enrolment in a health insurance scheme.

Conclusion

The study has shown that enrolment in a health insurance scheme is high among PLHIV, and being single, self-employed, having a smaller family size, and having a higher monthly income are predictors of enrolment in the health insurance scheme. Increasing the number of dependants that can be enrolled so that larger families can be motivated to enrol in health insurance is recommended.

Incorporation of Social Determinants of Health in the Peer-Reviewed Literature: A Systematic Review of Articles Authored by the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention

OBJECTIVES

Social determinants of health (SDHs) are the complex, structural, and societal factors that are responsible for most health inequities. Since 2003, the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) has researched how SDHs place communities at risk for communicable diseases and poor adolescent health. We described the frequency and types of SDHs discussed in articles authored by NCHHSTP.

METHODS

We used the MEDLINE/PubMed search engine to systematically review the frequency and type of SDHs that appeared in peer-reviewed publications available in PubMed from January 1, 2009, through December 31, 2014, with a NCHHSTP affiliation. We chose search terms to identify articles with a focus on the following SDH categories: income and employment, housing and homelessness, education and schooling, stigma or discrimination, social or community context, health and health care, and neighborhood or built environment. We classified articles based on the depth of topic coverage as "substantial" (ie, one of ≤3 foci of the article) or "minimal" (ie, one of ≥4 foci of the article).

RESULTS

Of 862 articles authored by NCHHSTP, 366 (42%) addressed the SDH factors of interest. Some articles addressed >1 SDH factor (366 articles appeared 568 times across the 7 categories examined), and we examined them for each category that they addressed. Most articles that addressed SDHs (449/568 articles; 79%) had a minimal SDH focus. SDH categories that were most represented in the literature were health and health care (190/568 articles; 33%) and education and schooling (118/568 articles; 21%).

CONCLUSIONS

This assessment serves as a baseline measurement of inclusion of SDH topics from NCHHSTP authors in the literature and creates a methodology that can be used in future assessments of this topic.

The cost-effectiveness of different feeding patterns combined with prompt treatments for preventing mother-to-child HIV transmission in South Africa: estimates from simulation modeling

Objectives

Based on the important changes in South Africa since 2009 and the Antiretroviral Treatment Guideline 2013 recommendations, we explored the cost-effectiveness of different strategy combinations according to the South African HIV-infected mothers' prompt treatments and different feeding patterns.

Study Design

A decision analytic model was applied to simulate cohorts of 10,000 HIV-infected pregnant women to compare the cost-effectiveness of two different HIV strategy combinations: (1) Women were tested and treated promptly at any time during pregnancy (Promptly treated cohort). (2) Women did not get testing or treatment until after delivery and appropriate standard treatments were offered as a remedy (Remedy cohort). Replacement feeding or exclusive breastfeeding was assigned in both strategies. Outcome measures included the number of infant HIV cases averted, the cost per infant HIV case averted, and the cost per life year(LY) saved from the interventions. One-way and multivariate sensitivity analyses were performed to estimate the uncertainty ranges of all outcomes.

Results

The remedy strategy does not particularly cost-effective. Compared with the untreated baseline cohort which leads to 1127 infected infants, 698 (61.93%) and 110 (9.76%) of pediatric HIV cases are averted in the promptly treated cohort and remedy cohort respectively, with incremental cost-effectiveness of $68.51 and $118.33 per LY, respectively. With or without the antenatal testing and treatments, breastfeeding is less cost-effective ($193.26 per LY) than replacement feeding ($134.88 per LY), without considering the impact of willingness to pay.

Conclusion

Compared with the prompt treatments, remedy in labor or during the postnatal period is less cost-effective. Antenatal HIV testing and prompt treatments and avoiding breastfeeding are the best strategies. Although encouraging mothers to practice replacement feeding in South Africa is far from easy and the advantages of breastfeeding can not be ignored, we still suggest choosing replacement feeding as far as possible.

Differences in access to healthcare and utilisation of HIV and sexually transmissible infection services between men who have sex with men and men who have sex only with women: results of the 2006–10 National Survey of Family Growth in the United States

Background Men who have sex with men (MSM) experience disparities in access to healthcare and have specific healthcare needs. Methods: We analysed data from the 2006–10 National Survey of Family Growth (NSFG) to examine differences in access to healthcare and HIV and sexually transmissible infection (STI) related health services by MSM and non-MSM among men in the United States aged 15–44 years who have ever had sex. MSM and sexually active MSM were identified in the NSFG as men who had ever had oral or anal sex with another man, or who had sex in the past 12 months with another man, respectively. Access was measured by the type of health insurance, having a usual place for receiving healthcare and type of usual place. Results: Of men aged 15–44 years who have ever had sex, there were no significant differences between MSM and non-MSM in the three access measures. MSM were more likely than non-MSM to receive HIV counselling (22.5% v. 8.3%) and STI testing (26.2% v. 15.6%) in the past 12 months, or to ever have had HIV testing (67.8% v. 44.6%). STI testing in the past 12 months was reported by 38.7% of sexually active MSM. Conclusion: Our findings show no significant differences in access to healthcare between MSM and non-MSM. MSM were more likely to receive HIV- and STI-related preventive services than non-MSM. However, the low STI testing rate among MSM highlights the need for interventions to increase STI testing, and HIV and STI counselling for MSM.

Summary of CDC consultation to address social determinants of health for prevention of disparities in HIV/AIDS, viral hepatitis, sexually transmitted diseases, and tuberculosis. December 9-10, 2008

In December 2008, the Centers for Disease Control and Prevention (CDC) convened a meeting of national public health partners to identify priorities for addressing social determinants of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), viral hepatitis, sexually transmitted diseases (STDs), and tuberculosis (TB). The consultants were divided into four working groups: (1) public health policy, (2) data systems, (3) agency partnerships and prevention capacity building, and (4) prevention research and evaluation. Groups focused on identifying top priorities; describing activities, methods, and metrics to implement priorities; and identifying partnerships and resources required to implement priorities. The meeting resulted in priorities for public health policy, improving data collection methods, enhancing existing and expanding future partnerships, and improving selection criteria and evaluation of evidence-based interventions. CDC is developing a national communications plan to guide and inspire action for keeping social determinants of HIV/AIDS, viral hepatitis, STDs, and TB in the forefront of public health activities.

The association between county-level injury rates and racial segregation revisited: a multilevel analysis

OBJECTIVES

We investigated whether within-county racial segregation was associated with increased odds of violent injury beyond individual risk.

METHODS

In a cross-sectional study, data on 75 310 patients admitted with an injury to Pennsylvania hospitals from 1997 to 1999 were analyzed to determine the association between county-level racial segregation and violent injury. We used multilevel analysis to adjust for individual- and county-level factors. Principal components analysis allowed us to separate the effect of segregation from other county-level variables.

RESULTS

After adjustment, greater segregation was associated with increased odds of violent injury among Whites (odds ratio [OR] = 1.20; 95% confidence interval [CI] = 1.11, 1.30) and non-Whites (OR = 1.45; 95% CI = 1.28, 1.64). The association was stronger for non-Whites.

CONCLUSIONS

Our results suggested that living in a county with high levels of racial segregation was associated with increased odds of violence not explained by an individual's own risk. These findings represent an important step in understanding the nature of observed links between race and violence. Future work should develop prevention strategies that simultaneously target community and individual risks.

Inpatient charges among HIV/AIDS patients in Rhode Island from 2000-2004

BACKGROUND

Inpatient HIV/AIDS charges decreased from 1996-2000. This decrease was mainly attributable to treatment of HIV/AIDS patients with Highly Active Antiretroviral Therapy (HAART). This study aims to evaluate the trend in inpatient charges from 2000-2004.

METHODS

Rhode Island Hospital Discharge Data (HDD) from 2000 to 2004 was used. International Classification of Disease (ICD-9) diagnosis code 042-044 was used to identify HIV/AIDS admissions. The final study population included 1927 HIV/AIDS discharges. We used a multivariable linear regression model to examine the factors associated with inflation adjusted inpatient charges.

RESULTS

We found a significant increase in inpatient charges from 2000-2004 after adjusting for length of stay (LOS), gender, age, race and point of entry for hospitalization. In addition to calendar year, LOS, gender and race were also associated with inpatient charges.

CONCLUSION

HIV/AIDS inpatient charges increased after adjusting for inflation despite earlier studies that showed a decline. Our results have implications for uninsured, as well as insured HIV/AIDS patients who do not have a medical plan that covers their charges sufficiently. Future research should investigate what factors are contributing to rising inpatient charges among HIV/AIDS patients.

Health care access among individuals involved in same-sex relationships

OBJECTIVES

We used data from the National Health Interview Survey to compare health care access among individuals involved in same-sex versus opposite-sex relationships.

METHODS

We conducted descriptive and logistic regression analyses from pooled data on 614 individuals in same-sex relationships and 93418 individuals in opposite-sex relationships.

RESULTS

Women in same-sex relationships (adjusted odds ratio [OR]=0.60; 95% confidence interval [CI]=0.39, 0.92) were significantly less likely than women in opposite-sex relationships to have health insurance coverage, to have seen a medical provider in the previous 12 months (OR=0.66; 95% CI=0.46, 0.95), and to have a usual source of health care (OR=0.50; 95% CI=0.35, 0.71); they were more likely to have unmet medical needs as a result of cost issues (OR=1.85; 95% CI=1.16, 2.96). In contrast, health care access among men in same-sex relationships was equivalent to or greater than that among men in opposite-sex relationships.

CONCLUSIONS

In this study involving a nationwide probability sample, we found some important differences in access to health care between individuals in same-sex and opposite-sex relationships, particularly women.

The impact of loss of Medicaid on health service utilization among persons with HIV/AIDS in New York City

OBJECTIVES

To examine predictors of losing Medicaid and the impact of losing Medicaid on health service utilization for persons living with HIV/AIDS.

DESIGN

The data are from the Community Health Advisory and Information Network (CHAIN), an on-going longitudinal survey representative of adults with HIV/AIDS in NYC (N = 698) (1994-1997 data). Change of Medicaid coverage between survey waves was considered a "transition" yielding three groups: "no transition", "transition to insurance", and "transition to no insurance".

METHODS

To determine predictors of transitions and the impact of transitions on health service utilization, multinomial logistic regression was used to compare the three groups.

RESULTS

There were 114 transitions and 792 cases without transitions, with transitions decreasing over time. Thirty percent of transitions were from Medicaid to no insurance. Transitions to insurance were more likely among the employed and those with incomes over 15,000 US Dollar. Transitions to no insurance were more likely among AIDS cases, recent immigrants, and people less than 30-year-old. People in both transition groups were less likely than people who retained Medicaid to have experienced a life event in the pre-transition period. Those with transitions to insurance reported decreased hospital and drug treatment. People who became uninsured reported decreased use of routine and preventive care, decreased health information and advice and decreased use of private doctors and outpatient clinics.

CONCLUSION

While the rate of transitions from Medicaid was relatively low, such transitions were associated with greater variability in quality of health care and greater difficulty accessing primary care among the uninsured.

The association of access to medical care with regular source of care and sociodemographic characteristics in patients with HIV and tuberculosis

PURPOSE

To examine satisfaction with access to health care in two populations, one with HIV and one with TB, and examine the effect of having a regular doctor and sociodemographic characteristics.

DESIGN

Cross-Sectional survey.

PATIENTS

A sample of HIV inpatients hospitalized at seven Los Angeles sites (N = 217) and TB outpatients chosen randomly from the Los Angeles County TB Registry Census (N = 313).

ANALYSIS

We performed bivariate and multivariate regression analyses of satisfaction with access to care on gender, race/ethnicity, age, education, income, insurance, and having a regular doctor.

MAIN OUTCOME MEASURES

A six-item scale of satisfaction with access to care (range 0-100; Cronbach's alpha 0.87).

RESULTS

The mean satisfaction with access score for the HIV sample was significantly lower than the TB sample (53.5 vs. 61.2, p<0.001). The HIV sample multivariate analysis (including all the variables) showed that increasing age (p<0.021 and having a regular doctor (p<0.002) were associated with better access, and that low income (p<0.005) was associated with poor access. In the TB sample analysis, only increasing age was associated with better satisfaction with access to care (p< 0.01).

CONCLUSION

HIV patients receiving care in the private sector reported less satisfaction with access to care compared to TB patients receiving care in the public health sector. The traditional factors of socio-economic status and having a regular doctor were associated with satisfaction with access-to-care in the HIV sample but not the TB sample. Our findings suggest that certain characteristics of the TB public health programs may explain these differences and suggests that, perhaps, the existence of a similar public health program for vulnerable low-income populations with HIV would improve their satisfaction with access, as well.

Costs of HIV medical care in the era of highly active antiretroviral therapy

OBJECTIVES

In the USA, Medicaid is the principal payer of the health care costs of patients with HIV infection. We wished to determine how the costs to Medicaid of patients in Maryland infected with HIV have changed in the setting of highly active antiretroviral treatment.

DESIGN

Observational cohort study.

METHODS

Analysis of combined economic and clinical data of patients from the Johns Hopkins HIV Service, the provider of primary and sub-specialty care for a majority of HIV-infected patients in the Baltimore metropolitan region. All patients were enrolled in Medicaid and received care longitudinally in Maryland from 1 January 1995 through 31 December 1997. Monthly Medicaid payments were calculated for all inpatient and outpatient services by fiscal year, CD4 cell count, and use of protease inhibitors.

RESULTS

For inpatients with a CD4 cell count < or = 50 x 10(6) cells/l, the total health care average monthly payments remained unchanged ($2629 in 1995, $2585 in 1997). Total mean monthly payments increased for those with a CD4 cell count > 50 x 10(6) cells/l (CD4 cell count 50-200 x 10(6) cells/l, $1172 in 1995 and $1615 in 1997, P < 0.05; CD4 cell count 201-500 x 10(6) cells/l, $1078 in 1995 and $1305 in 1997, P < 0.05). However, when data were stratified according to use of a protease inhibitor-containing regimen (used during approximately 50% of follow-up time in 1996-1997) it was found that hospital inpatient payments decreased significantly in all CD4 strata for patients on a protease inhibitor-containing regimen whereas pharmacy payments increased significantly. Inpatient payments associated with treating opportunistic illness were lower in 1996-1997 for patients receiving protease inhibitor therapy compared with those not receiving protease inhibitors. On balance, total health care payments tended to be slightly lower for patients receiving a protease inhibitor regimen.

CONCLUSION

Although protease inhibitor-containing antiretroviral regimens are being used by only about half of our Medicaid-insured patients, when they are used, there are significantly lower hospital inpatient and community care costs, as well as lower costs associated with the treatment of opportunistic illness. Even with the concurrent increase in their pharmacy costs, total health care costs were stable or slightly lower for these patients. We believe this is a favorable result suggesting a good clinical value being achieved without an increase in costs.

Emergency department-based HIV screening and counseling: experience with rapid and standard serologic testing

STUDY OBJECTIVE

We sought to (1) determine whether some emergency departments could play an important role in the national strategy of early HIV detection through the implementation of a voluntary HIV screening program and (2) describe the experience with standard and rapid HIV testing.

METHODS

Consenting adults were enrolled during 3 distinct phases between 1993 and 1995 for the assessment of routine testing only, routine versus rapid testing, and rapid testing only. Patients administered the rapid test were given information at the time of the visit. We assessed the cost of the program.

RESULTS

Of 3,048 patients approached, 1,448 (48%) consented, 981 to standard and 467 to rapid testing. Of these, 6.4% and 3.2%, respectively, were newly identified as being HIV seropositive. More than twice as many new infections were diagnosed among those discharged from the ED as among those admitted (55 versus 21). Even among those previously tested, 5% proved seropositive. The mean+/-SD time to obtain results for the rapid assay performed in the hospital's main laboratory was 107+/-52 minutes, with 55% leaving the ED before receiving the results. Rapid assays performed in the ED satellite laboratory required 48+/-37 minutes, and only 20% left before getting the results. Follow-up among HIV-seropositive patients was 64% for the standard protocol and 73% for the rapid protocol (P >. 20). The prearranged HIV clinic intake appointment was kept by 62%. Rapid test sensitivity and specificity were 100% and 98.9%, respectively, with 5 initial false-positives and no false-negatives. Cost per patient enrolled and counseled was $38. Cost per infection detected was $601 for the routine test and $1,124 with the rapid test; these prices are competitive with those incurred at other sites.

CONCLUSION

Emergency department-based HIV testing was well accepted and detected a significant number of new HIV infections earlier than might have otherwise been, particularly among patients sent home. The rapid test is best performed on-site and is very sensitive. Confirmation of initial results is required because of the occurrence of occasional false-positive results. With relatively high HIV detection and return rates, it is evident that some EDs could play a major role in the national strategy of early HIV detection.

Cost and Financing of Care for Persons With HIV Disease: An Overview

This article explores the impact of new combination drug therapies on the cost and financing of human immunodeficiency virus (HIV) disease. Evidence indicates that the proportion of costs attributable to drugs has increased significantly since the diffusion of new combination drug therapies, and that the proportion of costs attributable to hospital inpatient care has decreased. The absence of timely data is the major difficulty in analyzing the impact of recent changes. Only two studies have examined costs since the diffusion of new combination drug therapies, and there are no recent studies of the insurance status of persons with HIV disease.

Insurance status among HIV+ Nebraskans

OBJECTIVES

(1) To measure the rates of insurance in a population of HIV+ status. (2) To test an hypothesis that persons with AIDS are more likely to be uninsured than those who are HIV+ without AIDS. (3) To test the hypothesis that persons who are HIV+ experience difficulties maintaining their health insurance.

METHODS

Clients of three service agencies were surveyed. Demographic information was used to eliminate duplicate responses. Of the potential 480 respondents, 238 returned the surveys, reflecting approximately 10% of the estimated number of HIV+ persons in Nebraska. Descriptive techniques were used to analyze the data, and chi-square techniques were used in group comparisons.

RESULTS

Forty-three percent of the respondents were covered by private insurance, and 22% lacked any health insurance coverage. Persons with AIDS were less likely to have private insurance coverage and more likely to be receiving Medicaid coverage, but less likely to be uninsured. HIV+ test results contributed to a loss of insurance for 25 respondents, and HIV or AIDS positive was a reason for 29 respondents being denied insurance.

Costs to Medicaid of advancing immunosuppression in an urban HIV-infected patient population in Maryland

Human immunodeficiency virus (HIV) infection is increasingly an urban disease in the United States, and Medicaid is the principal payer of the health care costs of patients with HIV. We wished to determine the costs to Medicaid of patients in Maryland infected with HIV as immunosuppression progresses, and to determine how costs varied by demographic characteristics of the patient. We analyzed combined economic and clinical data in patients from the Johns Hopkins HIV Service, the provider of primary and specialty care for a majority of HIV-infected patients in the Baltimore metropolitan region. All patients were enrolled in Medicaid and received care longitudinally in Maryland from July 1992 to June 1995. Monthly Medicaid payments were calculated for all inpatient and outpatient services by sex, race, age, use of injecting drugs, CD4+ count (>500, 201-500, 51-200, < or =50 cells/mm3), several opportunistic diseases, and death. Lifetime costs were also calculated by use of a Markov simulation. During 13,174 person-months of follow-up in 606 patients, a total of $18,223,700 in Medicaid payments was made. Mean monthly payments ranged from $2,436 (SE $171) for patients with CD4+ counts < or =50 cells/mm3 to $1,015 (SE $177) for patients with CD4+ counts >500 cells/mm3. Mean monthly inpatient costs ranged from $1,355 (SE $131) for CD4+ counts < or =50 cells/mm3 and $617 (SE $164) for CD4- counts >500 cells/mm3. For those with CD4+ counts < or =50 cells/mm3, outpatient pharmacy costs averaged $515 (SE $57) monthly, second only to inpatient costs. In bivariate analysis, costs were significantly higher (p = .013) in men (mean $1696; SE $126) than in women (mean $1,208; SE $101), though the difference was not significant with multivariate adjustment. Cytomegalovirus retinitis was the most costly opportunistic disease, with mean monthly costs of $7,825 (SE $1,141) within the 6 mo after diagnosis. Within 6 mo of death, mean monthly costs are $4,600 (SE $424). Lifetime costs for treating an HIV-infected patient who presents with a CD4+ count >500 cells/mm3 are $133,500 over 8.3 years of life. We concluded that in the clinic where the analysis was done, average costs to Medicaid of treating patients increase more than two-fold as the CD4+ count declines from >500 cells/mm3 to < or =50 cells/mm3. Interventions that decrease hospitalization, opportunistic disease, and the costs of terminal care may be most likely to decrease overall costs. Demographic patient characteristics do not affect costs significantly when access to care is comparable.

Feasibility of an emergency department-based, risk-targeted voluntary HIV screening program

STUDY OBJECTIVE

To assess the feasibility and effectiveness of an emergency department-based, risk-targeted voluntary HIV screening program.

METHODS

We prospectively enrolled consenting adult i.v. drug users (IDUs) not known to have HIV infection in the ED of a large inner-city hospital with a high rate of HIV infection among patients during a 10-week trial. Study patients were given confidential HIV pretest and risk-reduction counseling, with 10- to 14-day on-site ED follow-up. Follow-up included posttest counseling, reinforcement of risk-reduction practices, and a +10 incentive to cover transportation costs. HIV seropositive patients were referred to the hospital HIV clinic for further evaluation and treatment.

RESULTS

Of 200 eligible IDUs, 168 (84%) consented to HIV testing. Of the 104 (62%) who returned for follow-up, 17 (16%) tested positive for HIV. Of these patients, 6 (35%) kept their initial hospital HIV clinic referral appointment, a rate consistent with the experience of the hospital HIV clinic. Of nine patients in whom CD4+ counts were performed at time of the visit, three (33%) had counts less than 200. At 3-month follow-up, 4 of 20 active IDUs (20%) had reportedly ceased drug use because of the program. The complete program costs was an estimated $16,659, $99 per enrolled patient and $521 per HIV-positive patient.

CONCLUSION

An ED-based, risk-targeted HIV screening program is feasible and over time could detect a significant number of asymptomatic HIV-infected individuals, including those who should receive antiretroviral therapy and prophylaxis for Pneumocystis carinii pneumonia therapy (CD4+ count less than 200). An additional benefit of ED-based HIV screening in high-prevalence EDs is the opportunity to conduct successful risk-reduction counseling in some high-risk individuals.

The supplement to HIV-AIDS Surveillance project: an approach for monitoring HIV risk behaviors

A variety of surveillance methods are used to characterize the epidemic of HIV infection and AIDS. Such surveillance includes AIDS case reporting, reporting of diagnosed HIV infections, and HIV seroprevalence surveys among targeted sentinel populations. The need for additional surveillance systems to monitor HIV-related risk behaviors has been increasingly evident. One approach to behavioral surveillance, the CDC's Supplement to HIV-AIDS Surveillance project, uses the infrastructure of HIV infection and AIDS case reporting to collect additional information on risk behaviors among HIV-infected persons, who by definition represent those at highest risk.

Pet ownership among persons with AIDS in three Florida counties

Interviews were conducted among 408 adults with acquired immunodeficiency syndrome at three local health departments to determine the proportion who owned pets, their perceived attachment to their pets, and the proportion who were informed about zoonoses. Nearly half (187, or 46%) were living with pets, most commonly dogs (64%), followed by cats (38%), fish (15%), birds (8%), reptiles (3%), and rodents (2%). Most pet owners (81%) reported an attachment to their pet. Only 10% were informed of zoonoses, albeit some incorrectly. Health care providers should recognize the high pet ownership rate among persons infected with human immunodeficiency virus and correctly inform their patients of strategies to sustain a low zoonotic disease incidence.

The types of drugs used by HIV-infected injection drug users in a multistate surveillance project: implications for intervention

OBJECTIVES

This study sought to describe the drugs used by drug injectors infected with human immunodeficiency virus (HIV) and to determine factors associated with the primary injection drug used.

METHODS

A cross-section of persons 18 years of age or older reported with HIV or acquired immunodeficiency syndrome (AIDS) to local health departments in 11 US states and cities was surveyed.

RESULTS

Of 4162 persons interviewed, 1147 (28%) reported ever having injected drugs. Of these 1147 injectors, 72% primarily injected a drug other than heroin. However, the types of drugs injected varied notably by place of residence. Heroin was the most commonly injected drug in Detroit (94%) and Connecticut (48%); cocaine was the most common in South Carolina (64%), Atlanta (56%), Delaware (55%), Denver (46%), and Arizona (44%); speedball was most common in Florida (46%); and amphetamines were most common in Washington (56%). Other determinants of the type of drug primarily injected were often similar by region of residence, except for heroin use. Polysubstance abuse was common; 75% injected more than one type of drug, and 85% reported noninjected drug use.

CONCLUSIONS

Preventing the further spread of HIV will require more drug abuse treatment programs that go beyond methadone, address polysubstance abuse, and adapt to local correlates of the primary drug used.
