Examining a syndemic framework for HIV and sexually transmitted infections Risk in Cali, Colombia.

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. Métodos: Utilizando datos de una campaña de consejería y pruebas de VIH en Cali, Colombia, probamos el efecto de la acumulación e interacciones de las cuatro condiciones psicosociales en la positividad al VIH y la positividad a otras enfermedades de transmisión sexual. Resultados: 604 participantes de las principales comunidades afectadas: hombres que tienen sexo con hombres, mujeres transgénero y trabajadoras sexuales. 733 participantes mujeres y hombres heterosexuales. Solo, abuso de drogas se asoció con positividad VIH (Razón de prevalencia = 2.3, IC 95%: 1.3–4.1), mientras que, todas las condiciones psicosociales se asociaron con historia de infecciones de transmisión sexual. La acumulación de condiciones sindémicas se relacionó con mayor probabilidad de historia de infecciones de transmisión sexual. Ninguna interacción probada fue significativa. Conclusiones: Nuestros hallazgos resaltan la importancia de intervenciones integrales de salud mental para abordar la epidemia de VIH en Colombia.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

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

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
