Interventions to Improve Retention in HIV Primary Care: A Systematic Review of U.S. Studies

Retaining HIV-diagnosed persons in care is a national priority, but little is known on what intervention strategies are most effective for promoting retention in care. We conducted a systematic search and qualitatively reviewed 13 published studies and three recent conference presentations to identify evidence-informed retention strategies. We extracted information on study design, methods, and intervention characteristics. Strengths-based case management that encourages clients to recognize and use their own internal abilities to access resources and solve problems offered strong evidence for retention in care. Other evidence-informed strategies included peer navigation, reducing structural- and system-level barriers, including peers as part of a health care team, displaying posters and brochures in waiting rooms, having medical providers present brief messages to patients, and having clinics stay in closer contact with patients across time. Opportunities for additional intervention strategies include using community-based organizations as a setting for engaging HIV-infected persons about the importance of regular care and involving patients’ significant others in retention in care interventions.

Health beliefs and intention to get immunized for HIV

PURPOSE The purpose of this study was to evaluate the relationship of health beliefs to intention to accept human immunodeficiency virus (HIV) vaccination. METHODS Respondents were 81 female and 44 male college students who completed self-administered questionnaires. Questionnaires included items assessing intention to get vaccinated for HIV and the following health beliefs: perceived susceptibility to HIV infection, severity of AIDS, benefits of HIV immunization, pragmatic obstacles to vaccination, conditional nonmembership in a risk group, fear of the vaccine, and fear of needles. RESULTS Nearly 30% of the subjects were uncertain about or opposed to getting immunized for HIV. Susceptibility, severity, pragmatic obstacles, conditional nonmembership in a risk group, and fear of the vaccine were significantly correlated with intent to get vaccinated. Fear of needles, gender, and race were not associated with intent to get an HIV vaccine. Multiple regression analysis identified susceptibility, benefits, pragmatic obstacles, nonmembership in risk group, and fear of the vaccine as significant independent predictors of intent to vaccinate. CONCLUSIONS These preliminary survey findings demonstrate that intention to accept HIV immunization is not universal and that health beliefs may influence HIV vaccine acceptance. They suggest that it may be important to consider the effects of psychological factors in future research on HIV vaccine acceptance and in the ultimate implementation of HIV immunization programs.

Efficacy of HIV/STI Behavioral Interventions for Heterosexual African American Men in the United States: A Meta-Analysis

This meta-analysis estimates the overall efficacy of HIV prevention interventions to reduce HIV sexual risk behaviors and sexually transmitted infections (STIs) among heterosexual African American men. A comprehensive search of the literature published during 1988–2008 yielded 44 relevant studies. Interventions significantly reduced HIV sexual risk behaviors and STIs. The stratified analysis for HIV sexual risk behaviors indicated that interventions were efficacious for studies specifically targeting African American men and men with incarceration history. In addition, interventions that had provision/referral of medical services, male facilitators, shorter follow-up periods, or emphasized the importance of protecting family and significant others were associated with reductions in HIV sexual risk behaviors. Meta-regression analyses indicated that the most robust intervention component is the provision/referral of medical services. Findings indicate that HIV interventions for heterosexual African American men might be more efficacious if they incorporated a range of health care services rather than HIV/STI-related services alone.

Hepatitis B virus infections and risk factors among the general population in Anhui Province, China: an epidemiological study

BackgroundHepatitis B is one of the most common infectious diseases in China. The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg) among the general population and the risk factors associated with HBV infection in Anhui province, China.MethodsA provincial serosurvey was conducted in four cities, and selected through stratified clustering sampling. Data on demographics, immunization history, medical history, family medical history, and life history were collected, along with serum tested for HBsAg. Completed surveys were analysed from 8,875 participants.ResultsOverall prevalence of HBsAg was 7.44%. Using multivariate analysis, older age was a risk factor for HBsAg infection among children younger than 15 years. Among adults 15-59 years old, the risk factors were male gender, a history of surgical operations, at least one HBsAg-positive family member, and non-vaccination. For adults older than 59 years, the risk factor was a blood transfusion history.ConclusionsThough Anhui province has already reached the national goal of reducing HBsAg prevalence to less than 1% among children younger than 5 years, there are still several risk factors for HBsAg infection among the older population. Immunization programs should continue to focus on adults, and interventions should be taken to reduce risk factors associated with being infected with Hepatitis B.

Health beliefs and vaccine costs regarding human papillomavirus (HPV) vaccination among a U.S. national sample of adult women.

OBJECTIVE Health beliefs have been found to be significant predictors of vaccine acceptability and uptake, including attitudes about HPV vaccine. In this study, we examined whether the predictive strength of health beliefs varied as a function of vaccine cost among adult women. METHODS During April 2009, data were collected from a nationally representative internet sample of 1323 US-resident women aged 27-55 years. Participants completed items related to sociodemographics, health beliefs, and HPV vaccine acceptability. Acceptability was measured at three levels of cost: free,

120/dose vaccine. CONCLUSION The results confirm previous findings that health beliefs predict HPV vaccine acceptability. However, the predictive strength of the association decreased with increasing cost. These findings suggest that interventions designed to increase vaccination by modifying health beliefs may have limited effect unless cost is minimized as a barrier.

The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative, clinical, and quality capture data from voluntarily participating anesthesia practices and health care facilities in the United States. All data are transmitted to the AQI in summary electronic files generated by billing, quality capture, and electronic health care record software, typically on a monthly basis. All data elements are mapped to fields in the NACOR schema in accordance with a publicly available data dictionary. Incoming data are loaded into NACOR by AQI technologists and are subject to both manual and automated review to identify systematically missing elements, miscoding, and inadvertent corruption. Data are deidentified in compliance with Health Insurance Portability and Accountability Act regulations. The database server of AQI, which houses the NACOR database, is protected by 2 firewalls within the American Society of Anesthesiologists’ network infrastructure; this system has not been breached. The NACOR Participant User File, a deidentified case-level dataset of information from NACOR, is available to researchers at participating institutions. NACOR architecture and the nature of the Participant User File include both strengths and weaknesses.
