Intention to notify sexual partners about potential HIV exposure among New York city STD clinics' clients

Innovation and implementation determinants of HIV testing and linkage-to-care in the U.S.: a systematic review

OBJECTIVE

To identify innovation and implementation determinants of HIV testing, diagnosis, and linkage-to-care in the U.S.

DATA SOURCES AND STUDY SETTING

Between November 2020 and January 2022, a broad search strategy was employed in three literature databases: Ovid MEDLINE, PsycINFO, and Web of Science.

STUDY DESIGN

A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

DATA COLLECTION/EXTRACTION METHODS

A team of master's and Ph.D.-level researchers screened eligible studies against the inclusion criteria and extracted the data using COVIDENCE software in pairs with consensus performed by a senior member of the team. Barriers and facilitators were extracted and analyzed according to the Consolidated Framework for Implementation Research (CFIR). Frequency of determinants across studies was mapped according to CFIR, valence, study design, delivery setting, unit of analysis, population of interest, region of the U.S., and year.

RESULTS

We identified 1,739 implementation and innovation determinants from 186 articles. Most determinants were for HIV testing rather than linkage-to-care. Most determinants were identified in the inner setting and individuals domains of CFIR, with the fewest identified in the process and innovations domains. Determinants of providers were only slightly more frequently identified than determinants of recipients. However, determinants of organizations and systems were rarely identified.

CONCLUSION

This review provides a synthesis of innovation and implementation determinants of HIV testing and linkage-to-care using the most-cited implementation science (IS) framework, CFIR. This synthesis enables the larger field of HIV science to utilize IS in efforts to end the HIV epidemic and positions IS to consider the application of IS frameworks to fields like HIV.

BASHH 2018 UK national audit of HIV partner notification

HIV partner notification (PN) is a highly effective strategy to identify people living with undiagnosed HIV infection. This national audit of HIV PN is against the 2015 British Association of Sexual Health and HIV (BASHH)/British HIV Association (BHIVA)/Society of Sexual Health Advisers (SHAA)/National AIDS Trust (NAT) HIV PN standards, developed in response to the 2013 BASHH/BHIVA national HIV PN audit. We report significant improvements in the number of contacts tested per index case, likely due, in part, to clearer definitions as well as better ascertainment and reporting. There remains scope for improvement with informing and testing contactable contacts. Recommendations from this audit include further refinement of definitions and development of a national proforma for HIV PN.

Protect MSM from HIV and other sexually transmitted diseases by providing mobile health services of partner notification: protocol for a pragmatic stepped wedge cluster randomized controlled trial

Background

Recently, more and more men who have sex with men (MSM) look for casual partners through online dating platforms in China. However, most are unable to know their partners’ HIV and other sexually transmitted diseases (STD) statuses, leading to the rapid increase in HIV infection among Chinese MSM. Effective partner notification is urgently needed to increase the risk awareness of MSM and prevent HIV and other STDs transmission. However, the traditional intervention mainly targets to the HIV-positive MSM and the effect is not promising. Our study aims to provide Internet-based partner notification, along with a series of health services for HIV-negative MSM to protect them from HIV and other STDs.

Methods

A pragmatic stepped wedge cluster randomized controlled trial design is used to evaluate the effectiveness of a new intervention paradigm, which aims to reduce HIV and other STDs incidences among MSM in China. Through integrating a mobile health (mHealth) service application (app) to the current HIV and other STDs prevention and control methods, the new paradigm provides partner notification of HIV, syphilis, hepatitis B, and hepatitis C statuses. A total of 6172 MSM in 16 districts of Beijing, China will be recruited and randomized to sequentially receive partner notification intervention through the app at 6-month intervals. The primary outcomes are HIV incidence and the additional cost of the intervention. The secondary outcomes include incidences of syphilis, hepatitis B, and hepatitis C, disease transmission social networks, testing adherence, knowledge of HIV and STDs control, health self-responsibility awareness, changes of high risk behaviors and other related outcomes. The generalized linear mixed models (GLMM) will be used to analyze the differences of outcomes in the control period and in the intervention period.

Discussion

We expect that the HIV incidence will be significantly lower and the secondary outcomes will also be improved with providing health service of partner notification through mhealth intervention. The feasible and affordable public health intervention paradigm will have implications for HIV and STDs prevention and control among MSM and other key populations.

Protecting Men Who Have Sex With Men From HIV Infection With an mHealth App for Partner Notification: Observational Study

Background

Traditional partner notification methods have been implemented for HIV-infected patients, as well as HIV treatment, in order to identify people at risk of HIV infection, especially men who have sex with men (MSM), since they are more likely to have casual sex partners. These traditional methods have some limitations.

Objective

Our study focused on developing an mHealth app to improve partner notification in practice for MSM; the study then focused on evaluating the effects of the app.

Methods

We developed an mHealth app with different modules using Java and HTML5 and tested it in an MSM community to prevent HIV transmission. The HIV incidence stratified by different follow-up periods were calculated. Poisson regression and social networks were used to estimate the risk ratios and to identify the connection among MSM, respectively.

Results

In addition to the partner notification module, which is the kernel of the app, we developed a test result self-query module to enable MSM to get their approved test results in a timely manner, a prompt and warning module to alert users to protect themselves from high-risk conditions, and a health education module to teach users more skills regarding HIV/AIDS prevention. Over a 1-year duration, a total of 3186 MSM used the app, of which 678 had at least two HIV test results since becoming app users; they were included in the final analysis. Among 678 users, a total of 6473 self-queries and 623 partner notifications were recorded, which identified 180 social networks of MSM app users. Those who used the partner notification function were more likely to have self-queries (P<.001). The 678 MSM app users covered 296.47 person-years and contributed to 20 HIV seroconversions; the cumulative HIV infection incidence was estimated as 6.75 per 100 person-years (95% CI 4.38-10.01). We found that the longer the app was used, the lower the HIV incidence (>5 months vs ≤5 months: 2.22 per 100 person-years vs 6.99 per 100 person-years; risk ratio 0.32, 95% CI 0.12- 0.87).

Conclusions

The app developed in this study is consistent with the World Health Organization’s sensitivity and confidentiality recommendations; it has the potential to reduce the risk of HIV infection among MSM.

Improving HIV test uptake and case finding with assisted partner notification services

OBJECTIVE

Despite the enormous expansion of HIV testing services (HTS), an estimated 40% of people with HIV infection remain undiagnosed. To enhance the efficiency of HTS, new approaches are needed. The WHO conducted a systematic review on the effectiveness of assisted partner notification in improving HIV test uptake and diagnosis, and the occurrence of adverse events, to inform the development of normative guidelines.

METHODS

We systematically searched five electronic databases through June 2016. We also contacted experts in the field and study authors for additional information where needed. Eligible studies compared assisted HIV partner notification services to passive or no notification. Where multiple studies reported comparable outcomes, meta-analysis was conducted using a random-effects model to produce relative risks (RRs) or risk ratios and 95% confidence intervals (CIs).

RESULTS

Of 1742 citations identified, four randomized controlled trials and six observational studies totalling 5150 index patients from eight countries were included. Meta-analysis of three individually randomized trials showed that assisted partner notification services resulted in a 1.5-fold increase in HTS uptake among partners compared with passive referral (RR = 1.46; 95% CI: 1.22-1.75; I = 0%). The proportion of HIV-positive partners was 1.5 times higher with assisted partner notification than with passive referral (RR = 1.47; 95% CI: 1.12-1.92; I = 0%). Few instances of violence or harm occurred.

CONCLUSION

Assisted partner notification improved partner testing and diagnosis of HIV-positive partners, with few reports of harm. WHO strongly recommends voluntary assisted HIV partner notification services to be offered as part of a comprehensive package of testing and care.

Recruitment approaches to identifying newly diagnosed HIV infection among African American men who have sex with men

To determine effectiveness of alternate venue testing (AVT), social network strategy (SNS) and provider referral (PR) for identifying previously undiagnosed HIV-infected 18-64-year-old African American men who have sex with men (AA MSM) by a health department. For AVT, staff used a mobile clinic to conduct HIV testing. For PR, staff solicited contact information from HIV-infected AA MSM, located contacts and offered HIV testing. For SNS, HIV-positive AA MSM recruited network associates for HIV testing. Two hundred and eighteen self-identified AA MSM were tested through AVT (25.2% HIV positivity) of whom 20 were newly identified HIV-positive. Fourteen HIV-positive men participated in SNS; 22 AA MSM contacts were recruited through SNS, eight (36.4%) were HIV positive and none were new positives. Two HIV-infected men participated in the PR strategy, yielding two AA MSM sex partners (one previously positive). The results suggest the need for health departments to consider using several complimentary strategies for identifying previously undiagnosed HIV infections in AA MSM in urban environments such as Baltimore.

Provision of test results and posttest counseling at STD clinics in 24 health departments: U.S., 2007

OBJECTIVE

We determined the demographic and HIV test characteristics of tests conducted in CDC-funded sexually transmitted disease (STD) clinics with provision of test results and posttest counseling.

METHODS

We used CDC's HIV Counseling and Testing System data from 2007 for the 24 U.S. health departments that reported test-level data from STD clinics. We calculated and analyzed newly identified HIV positivity and the percentage of tests with provision of test results and posttest counseling (provision of posttest counseling), by demographic and HIV-related characteristics.

RESULTS

Of 372,757 tests conducted among people without a previous HIV diagnosis by self-report, provision of posttest counseling was documented for 191,582 (51.4%) HIV tests overall and 1,922 (71.2%) newly identified HIV-positive test results. At these STD clinics, provision of posttest counseling varied by HIV serostatus, age, race/ethnicity, test type, and risk category; however, documentation of posttest counseling was missing for more than 20% of tests. The newly identified HIV positivity among all testers was 0.7%.

CONCLUSIONS

One of the main goals of HIV counseling and testing is to inform people of their HIV status, because knowledge of one's HIV-positive serostatus can result in a reduction in risk behaviors and allow the person to access HIV medical care and treatment. STD clinics offering HIV testing may need to further their emphasis on increasing the proportion of clients who are provided posttest counseling and on improving documentation of this information.

Evaluation of the relative effectiveness of three HIV testing strategies targeting African American men who have sex with men (MSM) in New York City

BACKGROUND

African American men who have sex with men (MSM) are disproportionately affected by HIV and constitute more than half of all HIV-infected MSM in the USA.

PURPOSE

Data from the New York City location of a multi-site study were used to evaluate the effectiveness of three HIV testing strategies for detecting previously undiagnosed, 18 to 64-year-old African American MSM. Effectiveness was defined as the identification of seropositive individuals.

METHODS

Using a quasi-experimental design (N = 558), we examined HIV-positive test results for men tested via alternative venue testing, the social networks strategy, and partner counseling and referral services, as well as behavioral risk factors for 509 men tested through alternative venue testing and the social networks strategy.

RESULTS

Detection rates of HIV-positives were: alternative venue testing-6.3%, the social networks strategy-19.3%, and partner services-14.3%. The odds for detection of HIV-positive MSM were 3.6 times greater for the social networks strategy and 2.5 times greater for partner services than alternative venue testing. Men tested through alternative venue testing were younger and more likely to be gay-identified than men tested through the social networks strategy. Men who tested through the social networks strategy reported more sexual risk behaviors than men tested through alternative venue testing.

CONCLUSIONS

Findings suggest differential effectiveness of testing strategies. Given differences in the individuals accessing testing across strategies, a multi-strategic testing approach may be needed to most fully identify undiagnosed HIV-positive African American MSM.

Partner notification after STD and HIV exposures and infections: knowledge, attitudes, and experiences of Massachusetts men who have sex with men

OBJECTIVES

We assessed Boston-area men who have sex with men (MSM) in terms of their knowledge of partner notification (PN)/partner counseling and referral services (PCRS) and intentions to use such services if exposed to/infected with a sexually transmitted disease (STD) or human immunodeficiency virus (HIV) in the future.

METHODS

The study used a convenience sample of STD clinic patients (n=48) and a modified respondent-driven sampling method (n=70) to reach a diverse sample of MSM (total sample n=118) in Massachusetts. Participants completed a one-on-one, open-ended, semistructured qualitative interview and quantitative survey.

RESULTS

Overall, white, HIV-infected MSM had the highest level of knowledge about PN activities. MSM who were unfamiliar with PN were disproportionately nonwhite and HIV-uninfected. Participants were more likely to notify past partners of HIV exposure than STD exposure. The preferred method of PN for the majority of MSM was direct person-to-person notification. Notably, nonwhite participants were more likely to endorse Massachusetts Department of Public Health PN services than white MSM, who preferred involvement of primary care providers.

CONCLUSIONS

PN is an important public health strategy for treating and preventing STDs and HIV among at-risk populations, especially MSM who engage in sexual behavior with anonymous or otherwise non-notifiable sexual partners. Although many MSM had an understanding of the ethical desirability of informing exposed partners and recognized the value of preventative behaviors, they require further education to overcome barriers to PN as well as to gain knowledge of the various methods of both traditional and nontraditional notification, such as Internet PN.

Partner Notification for Gonococcal and Chlamydial Infections in Men Who Have Sex With Men: Success Is Underestimated by Traditional Disposition Codes

BACKGROUND

Recent reports evaluating partner notification (PN) efforts among men who have sex with men (MSM) have observed relatively poor outcomes. However, the validity of traditional PN disposition codes is not known, possibly leading to overly pessimistic assessments of PN outcomes.

OBJECTIVES

To evaluate PN practices among MSM with gonococcal or chlamydial infection, assess the utility of offering MSM PN assistance and compare patient self-reported PN outcomes with those recorded using Disease Intervention Specialist (DIS) disposition codes.

STUDY DESIGN

We reviewed the records of all MSM with gonococcal or chlamydial infection interviewed by Public Health-Seattle and King County for purposes of PN in 2004. Men were asked to indicate whether each of their sex partners were already notified or treated at time of interview and were offered PN assistance.

RESULTS

DIS interviewed 409 of 628 (65%) MSM reported with gonococcal or chlamydial infection. Three hundred thirteen of the 409 (76%) interviewed men provided information about their number of sex partners in the 60 days before diagnosis and specific information about 1 or more of their potentially exposed partners. These index cases reported a total of 1037 sex partners, but provided information about only 634 (61%). Two hundred thirteen of the 313 (68%) index cases reported notifying at least 1 partner. Index cases reported that 295 of all 1037 (28%) reported partners had been notified, and that 170 (16%) were treated; DIS disposition codes documented the treatment of 111 (11%) partners. Only 18 (6%) index cases requested DIS assistance contacting a partner; DIS notified and assured the treatment of 24 of the 35 (69%) partners reported by these 18 men.

CONCLUSIONS

Although MSM with gonorrhea or chlamydia seldom accept assistance notifying partners, they report higher levels of partner treatment than suggested by DIS disposition codes, with 68% indicating that they had notified at least 1 sex partner and 46% reporting that at least 1 of their partners received treated.

The effectiveness of HIV partner counseling and referral services in increasing identification of HIV-positive individuals a systematic review

Partner counseling and referral services (PCRS) are part of the spectrum of care for HIV-positive people and their sexual or needle-sharing partners. Referral includes notifying partners of exposure, after which they are (ideally) tested and receive prevention or risk reduction counseling or enter into care (if they test positive). Using The Guide to Community Preventive Services's methods for systematic reviews, the effectiveness of PCRS was evaluated, including partner notification, in identifying a population at high risk of HIV infection and in increasing testing in those populations. In this review, PCRS efforts using provider referral were found to be effective in reaching a population with a high prevalence of HIV. Nine studies qualified for the review. In these studies, a range of one to eight partners was identified per index case (a person newly diagnosed with HIV who has partners who should be notified); a mean of 67% of identified partners were found and notified of their potential exposure to HIV, and a mean of 63% of those notified were tested (previously known "positives" were not tested). Of those tested, a mean of 20% were HIV positive. Therefore, even given that not all partners could be found and notified and that some who could be found did not accept testing, 1% to 8% of people named as potentially exposed and not previously known to be HIV positive were identified as HIV positive through partner notification (although these people were not necessarily infected by the index case). Evidence was insufficient to determine whether PCRS, including partner notification, was also effective in changing behavior or reducing transmission because available studies did not generally report on these outcomes. Little empirical evidence was available to assess potential harm of the interventions, but current studies have not shown substantial harms. Based on Community Guide rules of evidence, sufficient evidence shows that PCRS with partner notification by a public health professional ("provider referral") effectively increases identification of a high-prevalence target population for HIV testing.

Partner notification for sexually transmitted diseases in Peru: knowledge, attitudes, and practices in a high-risk community

OBJECTIVES

Notification and treatment of sex partners after diagnosis of a sexually transmitted disease (STD) is essential to reduce reinfection and further transmission.

GOAL

The goal of this study was to determine the prevalence of partner notification and subsequent health-seeking behavior in a high-risk population in Lima, Peru.

STUDY DESIGN

STD-infected participants of an HIV/STD prevention trial completed a questionnaire concerning partner notification.

RESULTS

Of the 502 STD-positive subjects, 287 completed the survey. Among survey participants, 65% informed their primary partner and 10.5% informed casual or anonymous partners. Reasons for failure to notify varied by partner type and included not understanding the importance of partner notification, embarrassment, fear of rejection, and inability to locate the partner. When notified, approximately one third of all partners sought medical attention.

CONCLUSIONS

Partner notification in Peru is limited by relationship dynamics, social stigma, and limited contact information. Interventions could emphasize the importance of notification, improvement of communication skills, and introduce contact tracing programs (including Internet-based systems) and expedited partner therapy.

Sexually acquired infections: do lay experiences of partner notification challenge practice?

AIM

This paper is a report of a study to explore experiences of partner notification for syphilis from the perspectives of gay, bisexual and other men who have sex with men.

BACKGROUND

Partner notification is the 'cornerstone' of the prevention and control of sexually acquired infections. As a health strategy, it has been in use for over six decades and is employed across all continents. Its success relies almost entirely on the voluntary response of index patients in disclosing details of their sexual partners and sexual practices and the voluntary response of sexual partners who have been traced. However, internationally, few studies have explicitly explored lay experiences of partner notification.

METHOD

A purposive sample of 40 gay, bisexual and other men who have sex with men was recruited from two genitourinary clinics in the Greater Dublin area of Ireland and a variety of gay social venues. Semi-structured interviews were carried out between December 2002 and February 2004.

FINDINGS

Men's perspectives on partner notification featured three interweaving stages: on tracing sexual partners, on informing partners and on attending clinics. Participants were in favour of partner notification, but did not find it easy to comply with the demands it made on their relationships. Compliance was difficult not only because of the problem of physically tracing casual and anonymous partners, but also because of the challenge of actually notifying partners. The main incentive for contacts to attend clinics was concern for their own health and that of others. Barriers to attending were fear of being exposed to the stigma of being gay and/or having a sexually acquired infection.

CONCLUSION

There is a need to develop evidence-based methods, which are grounded in the lay experience, to support index patients in 'breaking bad news' and for continued efforts to de-stigmatize sexually acquired infections and homosexuality in the view of the general public.

Partner Notification for Sexually Transmitted Diseases

Partner notification, a principal means of controlling sexually transmitted diseases, has traditionally been performed by public health professionals. They interview infected persons and contact the sex partners of these persons to notify them and convince them of the need to seek evaluation and treatment (known as "provider referral"). This notification method is labor intensive; the typical alternative to provider referral is to leave notification to the infected person (known as "patient referral"). However, innovations in partner notification, often created by public health professionals responsible for the practice, have yielded adjuncts and complements to both provider and patient referral. The present review article covers 4 areas of innovation: (1) enhancements to patient referral instructions and provider interview techniques, (2) use of the Internet in partner notification, (3) the emerging influence of network methods, and (4) expedited partner therapy, principally through patient-delivered medications or prescriptions. Partner notification remains necessary, and flexibility, openness to the use of multiple methods, and collaboration are likely to be helpful.

A systematic review of HIV partner counseling and referral services: client and provider attitudes, preferences, practices, and experiences

OBJECTIVES

The objectives of this study were to understand client and provider attitudes, experiences, and practices regarding HIV partner notification in the United States and to help identify future research and program needs.

GOALS

The goals of this study were to synthesize the literature reporting client and provider attitudes, experiences, and practices and to identify potential negative effects of HIV partner notification.

STUDY DESIGN

This study consisted of a systematic qualitative review.

RESULTS

Clients were willing to self-notify partners and participate in provider notification, and few reported negative effects. The majority of health care providers were in favor of HIV partner notification; however, they did not consistently refer index clients to HIV partner notification programs.

CONCLUSION

Considering that clients have positive attitudes toward self- and provider referral, local HIV prevention programs need to ensure that all HIV-positive clients are offered partner notification services. Additional research is needed to assess the potential risks of notifying partners and to identify effective techniques to improve client and provider participation.
