Increasing AIDS case reports in the South: U.S. trends from 1981–2004

Attitudes of North Carolina law enforcement officers toward syringe decriminalization

BACKGROUND

North Carolina, like much of the U.S. South, is disproportionately affected by HIV and hepatitis. This persistently high disease burden may be driven in part by laws that criminalize the possession and distribution of syringes for illicit drug use. Legal change to decriminalize syringes may reduce infection rates in the state, but is unlikely absent support from law enforcement actors.

METHODS

We analyzed the responses of 350 North Carolina law enforcement officers to a confidential, anonymous survey. The survey instrument collected data regarding self-reported needle-stick injury (NSI), blood borne disease risk perception and attitudes toward syringe decriminalization.

RESULTS

82% of respondents reported that contracting HIV was a "big concern" for them. 3.8% of respondents reported ever receiving a job-related NSI, a rate of 36 NSI per 10,000 officer-years. Majorities of respondents reported positive views regarding syringe decriminalization, with approximately 63% agreeing that it would be "good for the community" and 60% agreeing that it would be "good for law enforcement." Black and female officers were significantly less likely to agree that on-the-job NSI was a "big concern" and significantly more likely to agree that it would be good for law enforcement.

CONCLUSIONS

These findings suggest that many North Carolina LEOs understand the public health benefits of syringe access programs and may be inclined to support syringe decriminalization legislation. Further research is indicated to determine the causes of observed differences in perceptions of bloodborne disease risk and attitudes toward syringe decriminalization by race and sex.

Maximising the effect of combination HIV prevention through prioritisation of the people and places in greatest need: a modelling study

BACKGROUND

Epidemiological data show substantial variation in the risk of HIV infection between communities within African countries. We hypothesised that focusing appropriate interventions on geographies and key populations at high risk of HIV infection could improve the effect of investments in the HIV response.

METHODS

With use of Kenya as a case study, we developed a mathematical model that described the spatiotemporal evolution of the HIV epidemic and that incorporated the demographic, behavioural, and programmatic differences across subnational units. Modelled interventions (male circumcision, behaviour change communication, early antiretoviral therapy, and pre-exposure prophylaxis) could be provided to different population groups according to their risk behaviours or their location. For a given national budget, we compared the effect of a uniform intervention strategy, in which the same complement of interventions is provided across the country, with a focused strategy that tailors the set of interventions and amount of resources allocated to the local epidemiological conditions.

FINDINGS

A uniformly distributed combination of HIV prevention interventions could reduce the total number of new HIV infections by 40% during a 15-year period. With no additional spending, this effect could be increased by 14% during the 15 years-almost 100,000 extra infections, and result in 33% fewer new HIV infections occurring every year by the end of the period if the focused approach is used to tailor resource allocation to reflect patterns in local epidemiology. The cumulative difference in new infections during the 15-year projection period depends on total budget and costs of interventions, and could be as great as 150,000 (a cumulative difference as great as 22%) under different assumptions about the unit costs of intervention.

INTERPRETATION

The focused approach achieves greater effect than the uniform approach despite exactly the same investment. Through prioritisation of the people and locations at greatest risk of infection, and adaption of the interventions to reflect the local epidemiological context, the focused approach could substantially increase the efficiency and effectiveness of investments in HIV prevention.

Adaptation and implementation of HoMBReS: a community-level, evidence-based HIV behavioral intervention for heterosexual Latino men in the midwestern United States

Over the past decade, the midwestern United States has witnessed a dramatic increase in its Latino population. The lack of culturally and linguistically congruent resources coupled with high incidence and prevalence rates of HIV among Latinos living in the Midwest merits attention. HoMBReS: Hombres Manteniendo Bienestar y Relaciones Saludables (Men Maintaining Wellbeing and Healthy Relationships) is a community-level social network intervention designed for Latino men. We describe the adaptation and implementation of HoMBReS for Latino men living in Indianapolis, Indiana, the second largest city in the Midwest. Five Navegantes (lay health educators) were trained; they provided a total of 34 educational charlas (small group didactic sessions). A total of 270 Latino men attended the charlas and were offered no-cost screening for HIV and sexually transmitted infections (STI). Three participants tested HIV positive and 15 screened positive for STI. The charlas coupled with the testing initiative, served as a successful method to increase sexual health knowledge among Latino men and to link newly-diagnosed HIV/STI-positive individuals to treatment and care. The adaptation and implementation of HoMBReS respond to the CDC and NIH call to increase HIV testing and service provision among vulnerable populations.

A Qualitative Study of Barriers to the Utilization of HIV Testing Services Among Rural African American Cocaine Users

This qualitative study is about barriers to the utilization of HIV testing as perceived by African Americans who have recently used cocaine and who live in the rural Delta region of Arkansas. Affordability, physical accessibility, and geographic availability were not perceived as barriers to HIV testing in this sample, yet acceptability was still perceived as poor. Acceptability due to social mores and norms was a major barrier. Many said testing was unacceptable because of fear of social costs. Many were confident of being HIV-negative based on risky assumptions about testing and the notification process. Small-town social and sexual networks added to concerns about reputation and risk. System approaches may fail if they focus solely on improving access to HIV services but do not take into consideration deeply internalized experiences of rural African Americans as well as involvement of the community in developing programs and services.

Correlates of posttraumatic growth among African Americans living with HIV/AIDS in Mississippi

Individuals diagnosed with HIV face a host of challenges post-diagnosis. At risk for negative psychological outcomes, persons living with HIV/AIDS may also experience posttraumatic growth (i.e., positive cognitive and emotional changes that may occur following HIV diagnosis). African Americans, in particular, experience poorer psychosocial and behavioral outcomes and greater HIV-related health disparities, and also tend to report more posttraumatic growth than European Americans. This exploratory study examined demographic, psychosocial, and behavioral correlates of posttraumatic growth among 45 African American adults living with HIV in Mississippi. Statistical methods included correlational analyses and independent sample t-tests. As measured by the Posttraumatic Growth Inventory, posttraumatic growth was associated with several demographic (i.e., age, education, employment, income), psychosocial (i.e., social support, coping self-efficacy, psychological distress [negative]), and behavioral variables (i.e., church attendance, abstinence from drugs, alcohol, and cigarettes). Findings indicate that African Americans living with HIV in underserved, under-resourced areas are capable of perceiving posttraumatic growth post-diagnosis. Moreover, research has shown that perceived positive growth is associated with important sociocultural, psychosocial, and behavioral factors that directly and/or indirectly influence health and treatment outcomes. Implications of findings are discussed.

Factors associated with quality of life among rural women with HIV disease

This cross-sectional study examined physical, psychological, and social factors associated with quality of life (QOL) among a sample of 399 rural women with HIV disease living in the Southeastern United States. Of the socio-demographic variables, age (p = .003), race (p < .0001), and time of HIV diagnosis (p = .03) were significantly associated with QOL. In bi-variate analysis, HIV symptoms (frequency and extent symptoms were bothersome), perceived stigma, internalized stigma, and depression were significantly and negatively associated with QOL whereas social support, problem-focused coping, perceived situational control, and healthy lifestyles were significantly and positively associated with QOL (all p < .0001). In adjusted analysis, HIV symptom frequency, depression, problem-focused coping, perceived situational control, perceived stigma, healthy lifestyles, and race remained significant predictors of QOL and explained 55% of the variance in QOL among the study participants (model F (7, 390) = 66.7; p < .0001). The study findings identify potential points of interventions to improve QOL among rural women with HIV disease.

Barriers and facilitators to engagement in HIV clinical care in the Deep South: results from semi-structured patient interviews

Delayed entry into HIV clinical care and poor retention during care has been associated with increased morbidity and mortality. To characterize the reasons for patients who eventually did enter HIV care after a delay and/or returned to care after a gap of 6 months or more, 130 semi-structured interviews about barriers to and facilitators for prompt entry into and sustained HIV clinical care were conducted in a clinic setting in the Deep South; responses were coded and analyzed quantitatively. Barriers or facilitators were positioned within superordinate categories of personal and structural barriers or facilitators and denial. Personal barriers for entry into care outweighed structural barriers, with denial being reported by 74% of the sample. Barriers to retention in care were more evenly distributed between personal and structural barriers, with denial being a barrier for 24%. Because of the high incidence of denial-based barriers, the role of this barrier and its resolution should be explored further.

Addressing research priorities for prevention of HIV infection in the United States

More than half a million Americans became newly infected with human immunodeficiency virus (HIV) in the first decade of the new millennium. The domestic epidemic has had the heaviest impact on men who have sex with men and persons from racial and ethnic minority populations, particularly black persons. For example, black men who have sex with men represent <1% of the US population but 25% of new HIV infections, according to Centers for Disease Control and Prevention estimates published in 2008. Although black and Hispanic women constitute 24% of all US women, they accounted for 82% of HIV infections among women in 2005, according to data from 33 states with confidential name-based reporting. There is a nearly 23-fold higher rate of AIDS diagnoses among black women (45.5 diagnoses per 100,000 women) and a nearly 6-fold higher rate among Hispanic women (11.2 diagnoses per 100,000 women), compared with the rate among white women (2.0 diagnoses per 100,000 women). Investigators from the HIV Prevention Trials Network, a National Institutes of Health-sponsored collaborative clinical trials group, have crafted a domestic research agenda with community input. Two new domestic studies are in progress (2009), and a community-based clinical trial feasibility effort is in development (2010 start date). These studies focus on outreach, testing, and treatment of infected persons as a backbone for prevention of HIV infection. Reaching persons not receiving health messages and services with novel approaches to both prevention and treatment is an essential priority for control of HIV infection in the United States; our research is designed to guide the best approaches and assess the impact of bridging treatment and prevention.

Lessons learned from an HIV adherence pilot study in the Deep South

OBJECTIVE

Adherence to treatment for chronic illnesses, including HIV disease, is a complex process, and needs practical interventions in poorly resourced clinic settings.

METHODS

This study tested the feasibility of an adherence intervention in 73 HIV-infected individuals in a Deep South public clinic based on Fisher & Fisher's Information-Motivation-Behavioral Skills Model.

RESULTS

There was high baseline adherence and unexpectedly high clinic attrition, and 27% of the intervention group received less than one-quarter of the planned intervention contacts. Refill rate was the adherence measure that correlated best with HIV viral load and CD4 count, and there was poor use of electronic adherence monitoring (MEMS). Interviewed individuals expressed positive feelings about audio-supported computer-assisted survey instruments (ACASI) and the intervention support.

CONCLUSIONS

This process evaluation showed feasible study components in this population and setting. Lessons learned included: (1) clinic retention is an important part of adherence; (2) telephone interventions may need to add additional technology and flexibility to maximize dose; (3) ongoing fidelity monitoring is important with motivational interviewing; (4) refill rate was the most accurate adherence assessment; (5) MEMS was not well-accepted; (6) ACASI was easily used in this population; and (7) individuals appreciated adherence support from a consistent caring individual.

Risk-based HIV testing in South Carolina health care settings failed to identify the majority of infected individuals

To provide evidence of large numbers of missed opportunities for early HIV diagnosis we designed a retrospective cohort study linking surveillance data from the South Carolina HIV/AIDS Reporting System to a statewide all payer health care database. We determined visits and diagnoses occurring before the date of the first positive HIV test and medical encounters were categorized to distinguish visits that were likely versus unlikely to have prompted an HIV test. Of the 4117 HIV-positive individuals newly diagnosed between 2001 and 2005, 3021 (73.4%) visited a South Carolina health care facility one or more times prior to testing HIV positive. Of these 3021, 1311 (43.4%) were late testers, and 1425 (47.2%) were early testers. Females were less likely than males to be late testers (odds ratio [OR] 0.55, 95% confidence interval [CI] 0.45-0.68), blacks were more likely than whites to be late testers (OR 1.37, 95% CI 1.10-1.71), and persons 50 years of age and older more likely to be late testers (OR 7.16, 95% CI 3.84-13.37). A total of 78.8% of the 13,448 health care visits for both late and early testers were for health care diagnoses unlikely to prompt an HIV test. These findings underscore the need for more routine HIV testing of adults and adolescents visiting health care facilities in order to facilitate early diagnosis.

Examining geographic and temporal variations of AIDS mortality: evidence of racial disparities

BACKGROUND

There is little literature on spatiotemporal trends of AIDS mortality among different race and gender groups. The purpose of the present study is to describe AIDS mortality geographically and temporally, and to determine if detected trends vary by race and gender.

METHODS

The Spatial Scan Statistic was employed to examine the geographic excess of AIDS mortality by race and gender in 24 Maryland jurisdictions between 1987 and 2003. Spatial analysis was conducted to identify clusters of excess mortality. The temporal scan statistic was used to explore time trends of AIDS mortality. Prospective space-time analysis was also conducted to verify if detected clusters persisted into the present.

RESULTS

Among 10,887 AIDS deaths, 77.5% occurred in African Americans. Geographic excesses of AIDS mortality were detected in Baltimore city, and Howard, Montgomery, Anne Arundel, Prince Georges and Baltimore counties. Over the study period, AIDS mortality peaked in 1995 and then sharply dropped until 1998, when it stabilized. However, the AIDS mortality of African-American women started oscillating upward in 1998.

CONCLUSION

This study quantitatively described geographic and temporal variations of AIDS mortality in Maryland by gender and racial groups. The results may inform development of programs to address HIV/AIDS while considering the groups most affected differentially by geographic area.

Barriers and facilitators to medication adherence in a southern minority population with HIV disease

Adherence to HIV medications has been an important focus over the past decade, but little is known about adherence barriers and facilitators specifically in that part of the United States known as the Deep South. Characteristics of the region may affect factors associated with adherence related to the patient, the patient-provider relationship, and the environment. A total of 20 HIV-infected clients of a large public infectious diseases clinic in the Deep South participated in one of three focus groups; themes were identified by content analysis. Barriers included the perceived burden of extra planning, denial, life stress, difficult characteristics of the medicines, social stigma, and shame. Facilitators included acceptance of the diagnosis, thinking about the consequences of not taking the medicines, prayer and spirituality, improvements in the medicines, and support from family and friends. In the South, faith and prayer may be strong facilitators that need to be considered when adapting existing adherence interventions.
