Applying implementation science frameworks to identify factors that influence the intention of healthcare providers to offer PrEP care and advocate for PrEP in HIV clinics in Colombia: a cross-sectional study.

BACKGROUND: Few studies have used implementation science frameworks to identify determinants of PrEP prescription by healthcare providers. In this work, we developed and psychometrically examined a questionnaire using the theoretical domains framework (TDF) and the consolidated framework for implementation research (CFIR). We used this questionnaire to investigate what factors influence the intention of healthcare providers to offer PrEP care and advocate for PrEP. METHODS: We conducted a cross-sectional study in 16 HIV healthcare organizations in Colombia. A 98-item questionnaire was administered online to 129 healthcare professionals. One hundred had complete data for this analysis. We used exploratory factor analysis to assess the psychometric properties of both frameworks, and multinomial regression analysis to evaluate the associations of the frameworks' domains with two outcomes: (1) intention to offer PrEP care and (2) intention to advocate for PrEP impmentation. RESULTS: We found support for nine indices with good internal consistency, reflecting PrEP characteristics, attitudes towards population needs, concerns about the use of PrEP, concerns about the role of the healthcare systems, knowledge, beliefs about capabilities, professional role, social influence, and beliefs about consequences. Notably, only 57% of the participants were likely to have a plan to care for people in PrEP and 66.7% were likely to advocate for PrEP. The perception of the need for PrEP in populations, the value of PrEP as a practice, the influence of colleagues, and seeing PrEP care as a priority was related to being less likely to be unwilling to provide or advocate for PrEP care. CONCLUSION: Our findings suggested the importance of multilevel strategies to increase the provision of PrEP care by healthcare providers including adquisition of new skills, training of PrEP champions, and strength the capacity of the health system.

Adaptation and Pilot Evaluation of an Intervention Addressing the Sexual Health Needs of Gay Men Living with HIV Infection in Colombia.

Interventions addressing the sexual health need of HIV-positive men who have sex with men (MSM) in Latin America are scarce. We adapted and evaluated GPS, a group-based intervention led by peers, developed using the Information-Motivation-Behavioral (IMB) model and motivational interviewing (MI). We used McKleroy et al framework to culturally adapt GPS to MSM living with HIV infection in Colombia. Then, a one-armed pilot trial examined changes in depressive symptoms, loneliness, self-efficacy for engaging in sexual risk reduction behaviors, sexual sensation seeking and sexual compulsivity at pre-intervention, post-intervention, and 3-month follow-up. These results were complemented with semistructured interviews with participants 3 months after the intervention. GPS was identified to be culturally acceptable with few changes in materials and exercises. Facilitators showed high levels of adherence and fidelity to MI principles. Seven of 11 eligible participants finished the intervention; GPS positively influenced self-efficacy for condom negotiation, depressive symptoms, and condomless anal sex with partners of unknown HIV status. Exit interviews revealed that GPS was well-designed, relevant, facilitated discussion of sex in a nonjudgmental manner, and helped make positive changes in participants' sexual lives. These results provided preliminary evidence of an intervention to address sexual and mental health of MSM living with HIV in Latin America.

Application of the "syndemics" theory to explain unprotected sex and transactional sex: A crosssectional study in men who have sex with men (MSM), transgender women, and non-MSM in Colombia. / Aplicación de la teoría de la "sindemia" para entender el sexo sin protección y el sexo comercial: un estudio transversal en hombres que tienen sexo con hombres (HSH), mujeres transexuales y hombres que no tienen sexo con hombres en Colombia

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TW) in Colombia are highly affected by HIV. To improve understanding of the role of HIV risk behaviors in HIV acquisition, we used the syndemic framework, a useful concept to inform prevention efforts. OBJECTIVE: To examine the effect of four psychosocial conditions, namely, forced sex, history of childhood sexual abuse, frequent alcohol use, and illicit drug use on unprotected sex and the synergistic effects ("syndemic" effects) of these conditions on HIV risk behavior. MATERIALS AND METHODS: We enrolled a total of 812 males (54.7% men who have sex with men, MSM; 7.3% transgender women, and 38% non-MSM). The participants were recruited from neighborhoods of low socioeconomic status through free HIV-counseling and -testing campaigns. We performed Poisson regression analysis to test the associations and interactions between the four psychosocial conditions and unprotected sex with regular, occasional, and transactional partners. To test the "syndemic" model, we assessed additive and multiplicative interactions. RESULTS: The prevalence of any psychosocial condition was 94.9% in transgender women, 60.1% in MSM, and 72.2% in non-MSM. A higher likelihood of transactional sex was associated in MSM (prevalence ratio (PR)=7.41, p<0.001) and non-MSM (PR=2.18, p< 0.001) with three or all four conditions compared to those with one condition. Additive interactions were present for all combinations of psychosocial problems on transactional sex n MSM. No cumulative effect or additive interaction was observed in transgender women. CONCLUSIONS: Our study highlights the need for bundled mental health programs addressing childhood sexual abuse, illicit drug use, and frequent alcohol use with other HIV prevention programs.

Introducción. Los hombres que tienen sexo con hombres (HSH), y las mujeres transgenero (MT) en Colombia continuan estando a mayor riesgo de VIH. Para entender como los comportamientos se asocian al VIH, se uso la teoria de la sindemia, la cual se ha considerado muy útil en el desarrollo de estrategias de prevención. Objetivo. Examinar el efecto de cuatro afecciones psicosociales, a saber: historia de sexo forzado, historia de abuso sexual infantil, consumo frecuente de alcohol y consumo de drogas ilícitas en las relaciones sexuales sin protección, así como los efectos sinérgicos (efectos "sindémicos") de estas afecciones sobre el comportamiento de riesgo para HIV. Materiales y métodos. Se hizo un estudio transversal que incluyó 812 participantes (hombres que tienen sexo con hombres, HSH: 54,7 %; mujeres transgénero: 7,3 % y hombres que no tenían sexo con otros hombres: 38 %). Los participantes se reclutaron en barrios de estratos socioeconómicos bajos a través de campañas gratuitas de asesoramiento y pruebas de HIV. Se hizo un análisis de regresión de Poisson para probar las asociaciones e interacciones entre las cuatro condiciones psicosociales y las relaciones sexuales sin protección con parejas regulares, ocasionales y comerciales. Para probar el modelo "sindémico" se evaluaron las interacciones aditivas y multiplicativas. Resultados. La prevalencia de cualquiera de las condiciones psicosociales fue de 94,9 % en mujeres transexuales, de 60,1 % en HSH y de 72,2 % en hombres que no tienen sexo con hombres. Se encontró una mayor probabilidad de tener sexo comercial en los HSH (razón de prevalencia (RP)=7,41, p<0,001) y en los que no tienen sexo con otros hombres (RP=2.18, p<0,001) con tres de las condiciones psicosociales, o con las cuatro, en comparación con aquellos con una sola condición. Las interacciones aditivas se registraron entre todas las combinaciones de problemas psicosociales con el sexo comercial en los HSH. No se observó un efecto acumulativo ni interacciones en mujeres transexuales. Conclusiones. El estudio resalta la necesidad de combinar programas de salud mental que aborden el abuso sexual infantil, el abuso de drogas y el consumo frecuente de alcohol con otros programas de prevención del HIV.

Examining a syndemic framework for HIV and sexually transmitted infections risk in Cali, Colombia / Examinando un marco sindémico para el VIH y el riesgo de infecciones de transmisión sexual en Cali, Colombia / Examinando um marco sindémico para o vih e o risco de infeções de transmissão sexual em Cali, Colômbia

Abstract Objective: We examined the role played by four psychosocial conditions: forced sex, early sexual initiation, and misuse of alcohol and illicit drugs on the risk of HIV and sexually transmitted infections in Cali-Colombia between 2013 and 2015. Methods: Using data from an HIV counseling and testing campaign in Cali, Colombia, we tested the effect of the accumulation and interactions of the four psychosocial conditions on both outcomes. Results: A total of 604 participants were representative subjects from key affected communities: men who have sex with men, transgender women and female sex workers. A total of 733 participants were heterosexual women and men. Only drug abuse was associated with HIV positivity (Prevalence ratio=2.3, CI 95%: 1.3-4.1), while all psychosocial conditions were associated with sexually transmitted infection history. The accumulation of the syndemic conditions was related to a higher likelihood of sexually transmitted infection history. None of the interactions tested was significant. Conclusions: Our findings highlight the importance of comprehensive mental health interventions in addressing HIV epidemics in Colombia.

Resumen Objetivo: Examinar el papel desempeñado por cuatro afecciones psicosociales: sexo forzado, iniciación sexual temprana, uso inadecuado de alcohol y drogas ilícitas en el riesgo de VIH e infecciones de transmisión sexual, en Cali-Colombia entre 2013-2015.

HIV Testing and Counselling in Colombia: Local Experience on Two Different Recruitment Strategies to Better Reach Low Socioeconomic Status Communities.

HIV testing rates remain very low in Colombia, with only 20% of individuals at risk ever tested. In order to tackle this issue, the Corporacion de Lucha Contra el Sida (CLS) has implemented a multidisciplinary, provider-initiated, population-based HIV testing/counselling strategy named BAFI. In this report, we describe the experience of CLS at reaching populations from low socioeconomic backgrounds in 2008-2009. Two different approaches were used: one led by CLS and local health care providers (BAFI-1) and the other by CLS and community leaders (BAFI-2). Both approaches included the following: consented HIV screening test, a demographic questionnaire, self-reported HIV knowledge and behaviour questionnaires, pre- and posttest counselling, confirmatory HIV tests, clinical follow-up, access to comprehensive care and antiretroviral treatment. A total of 2085 individuals were enrolled in BAFI-1 and 363 in BAFI-2. The effectiveness indicators for BAFI-1 and BAFI-2, respectively, were HIV positive-confirmed prevalence = 0.29% and 3.86%, return rate for confirmatory results = 62.5% and 93.7%, return rate for comprehensive care = 83.3% and 92.8%, and ART initiation rate = 20% and 76.9%. Although more people were reached with BAFI-1, the community-led BAFI-2 was more effective at reaching individuals with a higher prevalence of behavioural risk factors for HIV infection.
