Among HIV-positive injection drug users (IDUs), we examined the correlates of lending needles/syringes with HIV-negative and unknown status injection partners. HIV-positive IDUs (N = 738) from 4 cities in the United States who reported injection drug use with other IDUs in the past 3 months participated in an audio computer-assisted self-administered interview. Eighteen percent of study participants self-reported having lent their needles to HIV-negative or unknown status injection partners. Multivariate analyses showed that 6 variables were significantly associated with this high-risk injecting practice. Older IDUs, high school graduates, and those reporting more supportive peer norms for safer drug use were less likely to lend needles/syringes. Admission to a hospital for drug treatment in the past 6 months, having injected with >1 person in the past 3 months, and having more psychiatric symptoms were all associated with more risk. These findings underscore the need for a continued prevention focus on HIV-positive IDUs that recognizes the combination of drug use, mental health factors, and social factors that might affect this high-risk injecting practice, which could be associated with HIV and hepatitis C transmission.

OBJECTIVES We examined the relationship between receipt of medical care for human immunodeficiency virus (HIV) infection and HIV transmission risk behavior among persons who had received a recent diagnosis of HIV infection. METHODS We enrolled 316 participants from 4 US cities and prospectively followed up participants for 1 year. Generalized estimating equations were used to examine whether having at least 3 medical care visits in a 6-month period was associated with unprotected vaginal or anal intercourse with an HIV-negative partner or partner with unknown HIV status. RESULTS A total of 27.5% of the participants (84 of 305) self-reported having unprotected sex with an HIV-negative or unknown status partner at enrollment, decreasing to 12% (31 of 258) and 14.2% (36 of 254) at 6-month and 12-month follow-ups, respectively. At follow-up, people who had received medical care for HIV infection at least 3 times had reduced odds of engaging in risk behavior, compared with those with fewer visits. Other factors associated with reduced risk behavior were being >30 years of age, male sex, not having depressive symptoms, and not using crack cocaine. CONCLUSIONS Being in HIV care is associated with a reduced prevalence of sexual risk behavior among persons living with HIV infection. Persons linked to care can benefit from prevention services available in primary care settings.

We interviewed 1038 HIV-positive inpatients in public hospitals in Miami, Florida, and Atlanta, Georgia, to examine patient factors associated with use of HIV care, use of antiretroviral therapy, and unprotected sexual intercourse. Multivariate analyses and multiple logistic regression models showed that use of crack cocaine and heavy drinking were associated with never having had an HIV-care provider, high-risk sexual behavior, and not receiving antiretroviral therapy. Inpatient interventions that link and retain HIV-positive persons in primary care services could prevent HIV transmission and unnecessary hospitalizations.

Lisa R. Metsch; Margaret Pereyra; Toye H. Brewer

PURPOSE We assessed the use of HIV care among HIV-seropositive crack cocaine smokers and other active drug users in Miami-Dade County, FL. METHODS Personal interviews were conducted with 327 adults recruited from inner city neighborhoods. Cross-tabulations and logistic modeling were used to analyze the relationship between selected variables and use of HIV care. RESULTS One-third of respondents had not seen a provider for HIV-related health care in the past 12 months. Among those who had seen a provider, only 33.8% were receiving highly active antiretroviral therapy (HAART). Factors associated with utilization of HIV-related health care were age, race, having a usual source of care, health insurance, time elapsed since time of diagnosis, and reports of moderate to extreme interference of pain with daily activities. IMPLICATIONS These findings suggest the need to develop, implement, and evaluate intervention strategies to improve use of HIV medical care among active drug users.

Substance abuse and welfare reform are among the nations highest priorities, and research that examines linkages between the two is of extreme importance to both government policy and the community. Welfare reform will have serious implications for substance abusers as well as for the various professionals who treat them and work to move their clients into functional recovery and self-sufficiency. Within the context of welfare reform and the special needs of substance-abusing populations, the present study examines current welfare status, work status, and barriers and facilitators to gaining and maintaining employment among ioo low income women who participated in a long-term residential substance-abuse treatment program in Miami, Florida. Participants completed a face-to-face interview to assess a detailed employment history and current sources of income as well as the Addiction Severity Index. Results indicate that completers of the treatment program were more likely to be working post-discharge than non-completers. Similarly, the longer the length of stay in the program, the more likely the client was to be working post-discharge. Multivariate analysis indicates a high-school education, participation in the treatment centers aftercare program, and treatment duration of more than one year were independently related to work status. These data suggest that as welfare reform becomes a reality, continuing support of various types, particularly drug treatment, is needed to assist substance-abusing women in gaining and maintaining employment.

OBJECTIVES We investigated the prevalence of HIV-positive patients discussing alcohol use with their HIV primary care providers and factors associated with these discussions. METHODS We recruited 1225 adult participants from 10 HIV care clinics in three large US cities from May 2004 to 2005. Multivariate logistic regression analysis was used to assess the associations between self-reported rates of discussion of alcohol use with HIV primary care providers in the past 12 months and the CAGE screening measure of problem drinking and sociodemographic variables. RESULTS Thirty-five percent of participants reported discussion of alcohol use with their primary care providers. The odds of reporting discussion of alcohol were three times greater for problem drinkers than for non-drinkers, but only 52% of problem drinkers reported such a discussion in the prior 12 months. Sociodemographic factors associated with discussion of alcohol use (after controlling for problem drinking) were being younger than 40, male, being non-white Hispanic (compared with being Hispanic), being in poorer health, and having a better patient-provider relationship. CONCLUSIONS Efforts are needed to increase the focus on alcohol use in the HIV primary care setting, especially with problem drinkers. Interventions addressing provider training or brief interventions that address alcohol use by HIV-positive patients in the HIV primary care setting should be considered as possible approaches to address this issue.

Welfare and Work Outcomes after Substance Abuse Treatment

Lisa R. Metsch; Margaret Pereyra; Christine Miles; Clyde B. McCoy

Employment and welfare outcomes are investigated for women who received both welfare and substance abuse treatment in Florida from 1994 to 1999. By linking information from three statewide administrative databases, we identify 4,236 women who meet both criteria. Over the study period, there was a significant increase in the proportion of women moving from welfare to work. Predictors of posttreatment employment include demographic characteristics, treatment‐related characteristics, and working during the month of admission. Both completion of treatment and length of time in treatment are associated with employment.

Abstract Non-adherence to medical regimens is a critical threat to HIV-infected individuals. Persons living with HIV/AIDS must adhere to their outpatient medical appointments to benefit from continually improving HIV care regimens. The primary purpose of the present study was to identify individual and psychosocial characteristics associated with HIV-related medical appointment non-attendance. One hundred seventy eight adult participants attending the Outpatient Adult HIV/AIDS Immunology Clinic at Jackson Memorial Hospital (JMH) in Miami, Florida participated in the study. Scheduled and missed appointments obtained retrospectively over a 12-month period indicated that medical appointment non-attendance was a significant problem. Overall, 27.9% of scheduled appointments were missed during the study period. Young age and limited family support were predictors of non-attendance. These findings support those of others and highlight targeted intervention efforts to reduce appointment non-attendance among persons living with HIV/AIDS.

Introduction Dental visits represent an opportunity to identify and help patients quit smoking, yet dental settings remain an untapped venue for treatment of tobacco dependence. The purpose of this analysis was to assess factors that may influence patterns of tobacco-use–related practice among a national sample of dental providers. Methods We surveyed a representative sample of general dentists practicing in the United States (N = 1,802). Multivariable analysis was used to assess correlates of adherence to tobacco use treatment guidelines and to analyze factors that influence providers’ willingness to offer tobacco cessation assistance if reimbursed for this service. Results More than 90% of dental providers reported that they routinely ask patients about tobacco use, 76% counsel patients, and 45% routinely offer cessation assistance, defined as referring patients for cessation counseling, providing a cessation prescription, or both. Results from multivariable analysis indicated that cessation assistance was associated with having a practice with 1 or more hygienists, having a chart system that includes a tobacco use question, having received training on treating tobacco dependence, and having positive attitudes toward treating tobacco use. Providers who did not offer assistance but who reported that they would change their practice patterns if sufficiently reimbursed were more likely to be in a group practice, treat patients insured through Medicaid, and have positive attitudes toward treating tobacco dependence. Conclusion Findings indicate the potential benefit of increasing training opportunities and promoting system changes to increase involvement of dental providers in conducting tobacco use treatment. Reimbursement models should be tested to assess the effect on dental provider practice patterns.

OBJECTIVE Earlier studies by this research team found that medically underserved minority women in the Miami-Dade County area of the state of Florida, United States, were in need of breast cancer screening and that there were problems with availability, accessibility, and acceptability of services. In response, a community-based comprehensive breast cancer screening program called the Early Detection Program (EDP) was developed. The specific purpose of this study was to assess the effect that EDP participation had on stage at diagnosis and on hazard of death. METHODS Existing data from the Florida Cancer Data System (FCDS), a statewide cancer registry, were linked with data from the EDP. In December 1998 we assembled a multiethnic (African-American, black Hispanic, white Hispanic, and white non-Hispanic) retrospective cohort with the following inclusion criteria: all women aged 40 and older with breast cancer diagnosed and staged at University of Miami/Jackson Memorial Medical Center (which is located in the city of Miami, Florida) from January 1987 through December 1997. EDP participants were medically underserved, that is, they resided in lower socioeconomic areas and/or had limited or no health insurance to cover medical costs. Subjects identified as EDP participants were compared to nonparticipants with respect to disease stage at diagnosis and hazard of death. Logistic regression and Cox regression models were used for analysis. RESULTS EDP participants were 2.4 times as likely (95% confidence interval = 1.71 to 3.43) to present with a diagnosis of localized cancer as were nonparticipants, even after controlling for race and age at diagnosis. EDP participation was independently associated with both earlier diagnosis and reduced hazard of death. CONCLUSIONS Participation in the EDP increases the likelihood of early detection of breast cancer and reduces the hazard of death for medically underserved women in the Miami-Dade County area of Florida. Interestingly, white Hispanics showed a better survival than did both African-Americans and white non-Hispanics. Our research also demonstrates the value of utilizing existing cancer registry data to evaluate a community-based program such as the EDP.
