Adapting positive prevention interventions for international settings: applying U.S. evidence to epidemics in developing countries

Capacity building, local ownership and implementation of a multi-level HIV/AIDS positive health, dignity, and prevention initiative in Mozambique: approach, challenges and lessons learned

Mozambique has for many years suffered from a high burden of HIV with an estimated prevalence of 11.1% among adults age 15–49 years. In response, Positive Health, Dignity, and Prevention (or Positive Prevention as it is known in Mozambique), was developed as a method of integrating HIV care and prevention via capacity building. Through comprehensive holistic care, HIV transmission is prevented while simultaneously promoting the health of people living with HIV/AIDS. Our initiative used a three-tiered approach, and included activities at national, provincial, and community levels. In order to change patient behavior and successfully train health-care workers in Positive Prevention, it was therefore considered necessary to work at multiple levels of influence. This ensured that the individual-level behavior change of PLHIV and health-care providers was maximized through supportive environments and policies. Related national-level achievements included the establishment of a Positive Prevention technical working group; the development of a Positive Prevention policy document; training national policy-makers on Positive Prevention; the development and distribution of a nationally approved Positive Prevention training package; the integration of Positive Prevention into existing Ministry of Health curricula; the development and approval of national data collection forms; and the drafting of a related national strategy. The framework and key activities of the Mozambique Positive Prevention Program may help to inform and assist others involved in similar work, as well as advancing country or local ownership of HIV/AIDS treatment, care and prevention efforts. By using a three-tiered approach, a supportive system was created. This was critical to both optimizing Positive Prevention provision and building long-term capacity. In order for related efforts to be successful in other settings, we encourage implementing partners to also work at multiple levels, with local ownership principles in mind, in order that Positive Prevention programs may have the greatest possible effect.

Effects of a peer educator program for HIV status disclosure and health system strengthening: Findings from a clinic-based disclosure support program in Mozambique

BACKGROUND

In Mozambique, HIV counseling and testing (HCT) rates are low and the cascade (or continuum) of care is poor. Perhaps more importantly, low disclosure rates and low uptake of joint testing are also related to both (1) limitations on access to services and (2) the availability of trained staff. We describe the implementation and impact of a disclosure support implemented by peer educators (PE).

METHODS

Ten PEs, previously trained in basic HIV and post-test counseling, completed additional training on providing disclosure support for newly-diagnosed persons living with HIV (PLH).

RESULTS

Of the 6,092 persons who received HCT, 677 (11.1%) tested positive. Any newly-diagnosed PLH who was tested when PEs were present (606 / 677) was approached about participating in the disclosure program; of these, 94.2% of PLH (n = 574) agreed to participate. Of these, at follow-up (between 1 day and 3 months later, depending on client inclination and availability) 91.9% (n = 528) said that they had disclosed their HIV infection, of whom 66.9% (n = 384) were female and 24.1% (n = 144) male. In turn, 92.7% of partners (n = 508) who had received HIV-related exposure information were tested; of these, 78.7% (n = 400) were found to be HIV-positive. Of the latter, 96.3% (n = 385) were then seen by health care providers and referred for further diagnosis and treatment.

CONCLUSIONS

Supporting newly-diagnosed PLH is important both for their own health and that of others. For the newly-diagnosed, there are extensive challenges related to understanding the implications of their illness; social support from clinical care teams can be vital in planning and coping. Our study has shown that such support of PLH is also crucial to disclosure, in part via improving awareness of positive health implications for (and from) family, friends and other support networks.

"It Had a Lot of Cultural Stuff in It": HIV-Serodiscordant African American Couples' Experiences of a Culturally Congruent Sexual Health Intervention

Objective

The increased life expectancy of people living with HIV has brought about an increase in serodiscordant couples, in which there is risk of HIV transmission. Therefore, interventions that promote sexual health and reduce risk are critical to develop for these couples. Given the disproportionate burden of HIV among populations of color, it is also critical that these interventions are culturally congruent. The EBAN intervention for African American serodiscordant couples recognizes the centrality of culture in shaping sexual behaviors and helps couples develop intimacy and positive prevention behaviors. The analytic objective of our study was to examine the knowledge and awareness gained by participants in the intervention.

Participants

Participants (n=17) who completed at least half of the eight intervention sessions.

Methods

Brief post-implementation semi-structured interviews were conducted between January 1, 2016 and December 31, 2016. Team-based, targeted content analysis focused on knowledge and awareness gains.

Results

Participants described learning about sexual health, expanded sexual options, and sexual communication. The "EBAN café," a component that gives couples a menu of options for safer sex behaviors, was particularly popular. Participants also noted the value of learning how to communicate with one another about their sexual health-related concerns and preferences. They appreciated the "cultural stuff" that was infused throughout the sessions, including the emphasis on learning from one another as couples.

Conclusions

Couples at risk for HIV transmission benefit from strengthening skills and knowledge related to healthy sexuality. A behavioral intervention that aligns with cultural values and imparts culturally congruent sexual health information appeals to couples who seek ways to enhance their intimacy and sexual options while also reducing risk.

Agents of change among people living with HIV and their social networks: stepped-wedge randomised controlled trial of the NAMWEZA intervention in Dar es Salaam, Tanzania

INTRODUCTION

NAMWEZA is a novel intervention that focuses on preventing HIV and promoting sexual and reproductive health and rights by addressing underlying factors related to vulnerability of acquiring HIV, such as depression, intimate partner violence (IPV) and stigma. The goal of the study was to evaluate the effect of the NAMWEZA intervention on risk behaviour as well as factors potentially contributing to this vulnerability for people living with HIV and their network members.

METHODS

A stepped-wedge randomised controlled trial was conducted from November 2010 to January 2014 among people living with HIV and their network members in Dar es Salaam, Tanzania. 458 people living with HIV were randomised within age/sex-specific strata to participate in the NAMWEZA intervention at three points in time. In addition, 602 members of their social networks completed the baseline interview. Intention-to-treat analysis was performed, including primary outcomes of uptake of HIV services, self-efficacy, self-esteem, HIV risk behaviour and IPV.

RESULTS

For people living with HIV, a number of outcomes improved with the NAMWEZA intervention, including higher self-efficacy and related factors, as well as lower levels of depression and stigma. IPV reduced by 40% among women. Although reductions in HIV risk behaviour were not observed, an increase in access to HIV treatment was reported for network members (72% vs 94%, p=0.002).

CONCLUSION

These results demonstrate the complexity of behavioural interventions in reducing the vulnerability of acquiring HIV, since it is possible to observe a broad range of different outcomes. This study indicates the importance of formally evaluating interventions so that policymakers can build on evidence-based approaches to advance the effectiveness of HIV prevention interventions.

System dynamics modeling of public health services provided by China CDC to control infectious and endemic diseases in China

BACKGROUND

Infectious and endemic diseases are a serious public health concern worldwide, and their prevention and treatment are globally controversial. This study aimed to establish an system dynamics (SD) model to analyze the factors influencing public health services provided by the Chinese Centers for Disease Control and Prevention (China CDC) to implement infectious and endemic disease control in China, by establishing more effective interventions to provide public health services and thus achieving the goal of controlling infectious and endemic diseases.

MATERIALS AND METHODS

An SD model was constructed using the Vensim DSS program. Intervention experiments were performed using the SD model, which reflected the influences on disease control by adjusting the governmental investment and compensation level for public health products.

RESULTS

The experimental results showed that increasing the governmental investment in China CDC and compensation level for public health products will significantly increase the public health product rate provided by China CDC.

DISCUSSION

Problems with infectious and endemic disease prevention and treatment are the result of the system's incomplete functioning and limited health resources. To address the current problems and improve the system, the government should increase its investment in the public health service system and improve the compensation system to ensure smooth implementation of infectious and endemic disease prevention and treatment and, ultimately, improve public health in China.

The Relationship of Repeated Technical Assistance Support Visits to the Delivery of Positive Health, Dignity, and Prevention (PHDP) Messages by Healthcare Providers in Mozambique: A Longitudinal Multilevel Analysis

BACKGROUND

Positive health, dignity, and prevention (PHDP) is Mozambique's strategy to engage clinicians in the delivery of prevention messages to their HIV-positive clients. This national implementation strategy uses provider trainings on offering key messages and focuses on intervening on 9 evidence-based risk reduction areas. We investigated the impact of longitudinal technical assistance (TA) as an addition to this basic training.

METHODS

We followed 153 healthcare providers in 5 Mozambican provinces over 6 months to evaluate the impact of on-site, observation-based TA on PHDP implementation. Longitudinal multilevel models were estimated to model change in PHDP message delivery over time among individual providers.

RESULTS

With each additional TA visit, providers delivered about 1 additional PHDP message ( P < .001); clinicians and nonclinicians started at about the same baseline level, but clinicians improved more quickly ( P = .004). Message delivery varied by practice sector; maternal and child health sectors outperformed other sectors.

CONCLUSION

Longitudinal TA helped reach the programmatic goals of the PHDP program in Mozambique.

The Impact of Visual Aids and Enhanced Training on the Delivery of Positive Health, Dignity, and Prevention Messages to Adult Patients Living with HIV in Rural North Central Mozambique

Introduction

Positive health, dignity, and prevention (PHDP) interventions target people living with HIV and AIDS (PLHIV) to promote well-being and prevent onward transmission. Concern that increased life expectancy and improved well-being would lead to increased risky sexual behaviour and subsequent HIV transmission motivated researchers to test novel strategies to support treatment adherence, encourage safer sex, STI treatment and partner testing, prevention of mother to child transmission, and support uptake of family planning.

Methods

We assessed the number and type of PHDP messages delivered to PLHIV before and after the implementation of an educational intervention for health providers combined with the distribution of visual job aids and monthly technical assistance.

Results

From April 21, 2013 to March 20, 2014, we documented 54,731 clinical encounters at three rural health centres in Zambézia province, Mozambique from 9,248 unique patients. The percentage of patients who received all seven PHDP messages during their last three visits was 1.9% pre-intervention vs. 13.6% post- intervention (p=<0.001). Younger patients (25 years vs. 35) and those with a recent HIV diagnosis (two weeks vs. two years) had higher odds of receiving any PHDP message (Odds Ratio [OR]: 1.22 and 2.79, respectively). Patients >59 days late collecting medications were not more likely to receive adherence messages than adherent patients (p=0.17).

Discussion

Targeting HIV prevention efforts to PLHIV is an effective HIV prevention approach to eliminate HIV transmission. Despite intensive training and support, PHDP message delivery remained unacceptably low in rural Mozambique. Patients at high risk for treatment abandonment were not more likely to be counselled about adherence and support measures, something that needs to be addressed.

Conclusions

We need to develop novel strategies to motivate health care providers to deliver these messages more consistently to all patients and develop a system that assists counsellors and clinicians to quickly and effectively determine which messages should be delivered.

HERMITAGE--a randomized controlled trial to reduce sexually transmitted infections and HIV risk behaviors among HIV-infected Russian drinkers

AIMS

This study assessed the effectiveness of HERMITAGE (HIV's Evolution in Russia-Mitigating Infection Transmission and Alcoholism in a Growing Epidemic), an adapted secondary HIV prevention intervention, compared with an attention control condition in decreasing sexually transmitted infections (STIs) and sex and drug risk behaviors among Russian HIV-infected heavy drinkers.

DESIGN

We conducted a single-blinded, two-armed, randomized controlled trial with 12-month follow-up.

SETTING

The study was conducted in St Petersburg, Russia. Participants were recruited from four HIV and addiction clinical sites. The intervention was conducted at Botkin Infectious Disease Hospital.

PARTICIPANTS

HIV-infected individuals with past 6-month risky sex and heavy alcohol consumption (n = 700) were randomized to the HERMITAGE intervention (n = 350) or an attention control condition (n = 350).

INTERVENTION

A Healthy Relationships Intervention stressing disclosure of HIV serostatus and condom use, adapted for a Russian clinical setting with two individual sessions and three small group sessions.

MEASUREMENTS

The primary outcome was incident STI by laboratory test at 12-month follow-up. Secondary outcomes included change in unprotected sex and several alcohol and injection drug use (IDU) variables.

FINDINGS

Participants had the following baseline characteristics: 59.3% male, mean age 30.1, 60.4% past year IDU, 15.4% prevalent STI and mean CD4 cell count 413.3/μl. Assessment occurred among 75 and 71% of participants at 6 and 12 months, respectively. STIs occurred in 20 subjects (8.1%) in the intervention group and 28 subjects (12.0%) in the control group at 12-month follow-up; logistic regression analyses found no significant difference between groups (adjusted odds ratio 0.63; 95% confidence interval = 0.34-1.18; P = 0.15). Both groups decreased unsafe behaviors, although no significant differences were found between groups.

CONCLUSIONS

The HERMITAGE HIV risk reduction intervention does not appear to reduce sexually transmitted infections and HIV risk behaviors in Russian HIV-infected heavy drinkers compared with attention controls.

Messages on pregnancy and family planning that providers give women living with HIV in the context of a Positive Health, Dignity, and Prevention intervention in Mozambique

Background

Family planning is an important HIV prevention tool for women living with HIV (WLHIV). In Mozambique, the prevalence of HIV among women of reproductive age is 13.1% and the average fertility rate is high. However, family planning and reproductive health for WLHIV are under-addressed in Mozambique. This study explores provider descriptions of reproductive health messages in order to identify possible barriers and facilitators to successfully addressing family planning and pregnancy concerns of WLHIV.

Methods

In 2006, a Positive Health, Dignity, and Prevention program was introduced in Mozambique focused on training health care providers to work with patients to reduce their transmission risks. Providers received training on multiple components, including family planning and prevention of mother-to-child transmission (PMTCT). In-depth interviews were conducted with 31 providers who participated in the training in five rural clinics in three provinces. Data were analyzed using qualitative content analysis.

Results

Analysis showed that providers’ clinical messages on family planning, pregnancy, and PMTCT for WLHIV could be arranged along a continuum. Provider statements ranged from saying that WLHIV should not become pregnant and condoms are the only valid form of family planning for WLHIV, to suggesting that WLHIV can have safe pregnancies.

Conclusion

These data indicate that many providers continue to believe that WLHIV should not have children and this represents a challenge for integrating family planning into the care of WLHIV. Also, not offering WLHIV a full selection of family planning methods severely limits their ability to protect themselves from unintended pregnancies and to fully exercise their reproductive rights. Responding to the reproductive health needs of WLHIV is a critical component in HIV prevention and could increase the success of PMTCT programs.

Change in sexual activity 12 months after ART initiation among HIV-positive Mozambicans

We assessed sexual behaviors before and 12-months after ART initiation among 277 Mozambicans attending an HIV clinic. Measured behaviors included the number of sexual partners, condom use, concurrent relationships, disclosure of HIV status, alcohol use, and partners' serostatus. Compared to before ART initiation, increases were seen 12 months after ART in the proportion of participants who were sexually active (48% vs. 64% respondents, P < 0.001) and the proportion of participants with HIV-negative or unknown serostatus partners (45% vs. 80%, P < 0.001). Almost all (96%) concurrent partnerships reported at 12 months formed after ART initiation. Although reported correct and consist condom use increased, the number of unprotected sexual relationships remained the same (n = 45). Non-disclosure of HIV-serostatus to sexual partners was the only significant predictor of practicing unprotected sex with partners of HIV-negative or unknown serostatus. Sexual activity among HIV-positive persons on ART increased 12 months after ART initiation. Ongoing secondary transmission prevention programs addressing sexual activity with multiple partners, disclosure to partners and consistent condom use with serodisconcordant partners must be incorporated throughout HIV care programs.
