Políticas nacionales para el control del VIH y la evolución de la epidemia en México: un análisis de 1990 a 2017.

OBJETIVO: Analizar los cambios en la carga de la enfermedad del VIH de 1990-2017 y la influencia de las políticas y programas implementadas para su prevención y control. Material y métodos. Se elaboró una línea de tiempo de políticas e intervenciones en México; mediante modelos de regresión JoinPoint, se analizó su relación con los cambios ocurridos en las tendencias de la carga de la enfermedad del VIH. RESULTADOS: Los cambios en la carga de enfermedad se relacionan con la universalización del acceso a los medicamentos antirretrovirales (ARV), programas de atención integral y el combate al estigma y la discriminación. En el periodo analizado se observa descenso de la mortalidad relacionado con el acceso universal y gratuito a los ARV. La magnitud de los cambios tiende a ser mayor en los hombres que en las mujeres. CONCLUSIONES: Las políticas y programas implementados para tratar a las personas con VIH/Sida en México se integraron en estrategias cada vez más cohesionadas y eficaces.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections in Tlaxcala, Mexico.

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are widely recognised as two prevalent sexually transmitted infections that can have detrimental effects on women's reproductive health. Previous research has concentrated on studying high-risk populations, resulting in limited epidemiological data regarding the general population. Therefore, the objective of this study was to estimate the prevalence of CT and NG among women attending public primary health care in Tlaxcala, Mexico. The study sample included 2,396 women already participating in the cervical cancer screening programme, from July to November 2014. After obtaining informed consent, the CT and NG tests were conducted on cervical samples, using a nucleic acid amplification test. We estimate the prevalence with 95% confidence intervals (CIs). Women who tested positive were promptly notified and provided with appropriate treatment. In our study population, CT and NG prevalences were 3.2 (95% CI: 2.6-4.0) and 0.01 (95% CI: 0.01-0.03), respectively. CT prevalence was higher in younger women (age < 40), although the results indicate a low prevalence; due to the potentially significant impact of CT and NG on women's health, we require adequate surveillance, and guaranteeing rapid referral to the correct treatment is a priority for the control of these diseases.

The next phases of the Migrante Project: Study protocol to expand an observatory of migrant health on the Mexico-U.S. border.

Background: Mexican migrants traveling across the Mexico-United States (U.S.) border region represent a large, highly mobile, and socially vulnerable subset of Mexican nationals. Population-level health data for this group is hard to obtain given their geographic dispersion, mobility, and largely unauthorized status in the U.S. Over the last 14 years, the Migrante Project has implemented a unique migration framework and novel methodological approach to generate population-level estimates of disease burden and healthcare access for migrants traversing the Mexico-U.S. border. This paper describes the rationale and history of the Migrante Project and the protocol for the next phases of the project. Methods/design: In the next phases, two probability, face-to-face surveys of Mexican migrant flows will be conducted at key crossing points in Tijuana, Ciudad Juarez, and Matamoros (N = 1,200 each). Both survey waves will obtain data on demographics, migration history, health status, health care access, COVID-19 history, and from biometric tests. In addition, the first survey will focus on non-communicable disease (NCD), while the second will dive deeper into mental health and substance use. The project will also pilot test the feasibility of a longitudinal dimension with 90 survey respondents that will be re-interviewed by phone 6 months after completing the face-to-face baseline survey. Discussion: Interview and biometric data from the Migrante project will help to characterize health care access and health status and identify variations in NCD-related outcomes, mental health, and substance use across migration phases. The results will also set the basis for a future longitudinal extension of this migrant health observatory. Analyses of previous Migrante data, paired with data from these upcoming phases, can shed light on the impact of health care and immigration policies on migrants' health and inform policy and programmatic responses to improve migrant health in sending, transit, and receiving communities.

Sex Work Venue Disorder and HIV/STI Risk Among Female Sex Workers in Two México-US Border Cities: A Latent Class Analysis.

Research increasingly recognizes the importance of social and built environments in shaping health, including risks for and outcomes related to HIV and sexually transmitted infections (STI), but research on sex work venues is limited. We use latent class analysis to identify patterns of sex work venue characteristics and factors associated with class membership in two México-US border cities. Among 603 female sex workers (FSW), three classes of sex work venues were identified: low, medium, and high disorder venues, characterized by level of violence, policing and drug activity. In multivariable analysis, risk exposures and outcomes varied by class, suggesting the need for place-based interventions that are tailored to specific venue profiles and that promote FSW health and safety in the workplace.

Hepatitis C elimination among people who inject drugs in Mexico during the COVID-19 pandemic.

In 2019, Mexico was one of the first countries in Latin America to commit resources to achieve hepatitis C elimination by 2030. One year after this commitment, the global COVID-19 pandemic diverted attention to address immediate health needs to combat the spread of the disease. As a result, efforts to implement hepatitis C prevention and management programs were indefinitely postponed. Furthermore, populations at high risk of contracting the hepatitis C virus (HCV) and who bear the greatest burden of HCV national epidemic, including people who inject drugs and people who live with human immunodeficiency virus infection, remain exposed to extreme health disparities, which have potentially been exacerbated during the COVID-19 pandemic. In this article, we discuss the potential impact the COVID-19 pandemic has had on HCV elimination efforts in Mexico and the urgent need to resume them, since without these efforts, HCV elimination goals are likely not be achieved in the country by 2030.

En 2019, México fue uno de los primeros países en Latinoamérica en comprometer recursos para eliminar la hepatitis C antes de 2030. Un año después de este compromiso, la pandemia mundial de COVID-19 desvió la atención hacia las necesidades inmediatas de salud para combatir la propagación de esta última. Como resultado, los esfuerzos para implementar programas de prevención y manejo de la hepatitis C se suspendieron indefinidamente. Asimismo, las poblaciones con alto riesgo de contraer el virus de la hepatitis C y que representan el mayor peso de la epidemia nacional, como las personas que se inyectan drogas y las personas que viven con infección por el virus de la inmunodeficia humana, permanecen expuestas a disparidades de salud extremas que potencialmente se han exacerbado durante la pandemia de COVID-19. En este artículo discutimos el impacto potencial que la pandemia de COVID-19 ha tenido sobre los esfuerzos de eliminación de la hepatitis C en México y la necesidad urgente de reanudarlos, ya que sin ellos los objetivos de eliminación no se alcanzarán en el país en 2030.

Transition from first illegal drug use to first injection among people who inject drugs in Northern Mexico: A retrospective survival analysis / Transición del primer consumo de drogas ilegales a la primera inyección entre las personas que se inyectan drogas en el norte de México: un análisis retrospectivo de supervivencia

Abstract Introduction There is little information in Mexico about the transition to injecting drugs among drug users in cities other than Tijuana. Objective We compare characteristics of the onset of drug use and first injection among people who inject drugs (PWID) from Ciudad Juárez and Hermosillo, two cities of Northern Mexico and identify factors associated with faster rates of transition from first drug use to the first injection. Method 841 PWID were interviewed in 2012 in Ciudad Juárez (n = 445) and Hermosillo (n = 396). Using lifetables, we describe timing at the onset of drug use and first injection. Cox regression analysis was used to determine factors associated with the transition hazard to first injection. Results Median age at onset of drug use was 15.5 years old (standard deviation [SD] = 5.73). The median age at first injection was 21.30 (SD = 7.22). The median duration-time between first drug use and transition to injection was 4.8 years (SD = 5.6). Controlling for sociodemographics, factors that increase the hazard of transitioning to injection are age at onset of drug use (adjusted-hazard-rate [AHR] = 1.04, 95% confidence-interval CI [1.03, 1.05], p<.01) having used cocaine, heroin, or methamphetamine at the onset of drug use (AHR = 1.14, 95% CI [1.03, 1.27], p = .01), and having received assistance at first injection (AHR = 1.25, 95% CI [1.17, 1.33], p<.01). Discussion and conclusion Results show the need to enhance harm reduction programs among non-injecting drug users so as to prevent the spread of injecting drugs in Mexico.

Resumen Introducción Existe poca información en México sobre los calendarios al uso inyectado de drogas en ciudades distintas a Tijuana. Objetivo Comparamos las características del inicio del consumo de drogas y la primera inyección entre las personas que se inyectan drogas (PID) de Hermosillo y Ciudad Juárez e identificamos factores asociados con la transición a la primera inyección. Método En 2012 encuestamos a 841 PID en Ciudad Juárez (n = 445) y Hermosillo (n = 396). Utilizando tablas de vida analizamos las edades al primer uso de sustancias ilícitas y de la primera inyección. Ajustamos un modelo de regresión Cox para determinar los factores asociados con el riesgo de transición a la primera inyección. Resultados La edad mediana al primer consumo de drogas fue 15.5 años (desviación estándar [DE] = 5.73). La edad mediana a la primera inyección fue 21.30 (DE = 7.22). La duración mediana entre el primer uso de drogas ilícitas y la primera inyección fue de 4.8 años (DE = 5.6). Controlando los factores sociodemográficos, los factores que aumentan el riesgo de transición a la inyección son la edad al inicio de uso de drogas ([AHR] = 1.04, intervalo de confianza [IC] del 95% [1.03, 1.05], p<.01) uso de cocaína, heroína o metanfetamina como droga de inicio (AHR = 1.14, IC 95% [1.03, 1.27], p = .01) y haber recibido asistencia en la primera inyección (AHR = 1.25, IC 95% [1.17, 1.33], p<.01). Discusión y conclusión Es necesario mejorar los programas de reducción de daños entre los consumidores de drogas no inyectables para prevenir la propagación del uso inyectado de sustancias en el norte de México.

Type 1 diabetes care in mexico: an analysis of the renaced-dt1 national registry

Background: Information regarding diagnosis, treatment, and follow-up of patients with type 1 diabetes (PWT1D) in Mexico is limited. We developed an on-line platform Registro Nacional de Pacientes con Diabetes Tipo 1 (RENACED-DT1). Objective: The objective of the study was to describe the characteristics and healthcare of PWT1D registered in RENACED-DT1. Methods: Analyses of 965 PWT1D from July 2014 to January 2018 in different endocrinology clinics around Mexico. Results: Sixty-one percent were female with median age of 21 years, age at diagnosis 11 years, and disease duration at inclusion 8.2 years. Treatment regimen was basal-bolus in 61% and insulin-pumps in 21% (mainly in the private sector); 33.3% with self-monitoring of blood-glucose (SMBG) ≥4 times/day. Mean HbA1c at last follow-up was 8.7 ± 2.1% (72±23 mmol/mol), 18% had HbA1c < 7% (53 mmol/mol), and 35% > 9% (75 mmol/mol). SMBG ≥ 4 times/day was associated with HbA1c < 7%. Time since diagnosis > 10 years, female sex, BMI ≥ 30 kg/m2, SMBG < 4 times/day, and any hypoglycemia were associated with microvascular complications (p < 0.05). Conclusions: Percentage of patients achieving HbA1c < 7% is low; increased blood glucose monitoring is associated with better glycemic control. The achievement of optimal glycemic control must be increased to reduce the incidence of chronic complications and improve quality of life in PWT1D.

Trends in Mortality by HIV/AIDS in Children in Mexico: Towards the Elimination of Mother-To-Child Transmission.

AIM OF THE STUDY: To examine mortality trends in children under 15 years of age due to HIV/AIDS in Mexico and describe their differences by insurance coverage. METHODS: Time series analysis of deaths from 1990-2019 through a Bayesian poisson regression model with linear splines and knots in 1994, 1997, and 2003. RESULTS: Overall, we observed a reduction in the mortality rate due to HIV from 2003 onwards, except in the group of 10-14 years. In the population covered with Social Security, mortality rates decreased in all age groups. However, in the group without Social Security or with Popular Security (subsidized system), mortality rates significantly decreased only for children below 5 years. of age. CONCLUSIONS: Health insurance through the contributory system is associated with faster and larger reductions in HIV related infant mortality. Universal access to health insurance was not sufficient to close the gap in HIV-mortality among children under 15 years of age in Mexico.

A comparison of the effectiveness of respondent-driven and venue-based sampling for identifying undiagnosed HIV infection among cisgender men who have sex with men and transgender women in Tijuana, Mexico.

BACKGROUND: Efforts to increase HIV testing, diagnosis and care are critical to curbing HIV epidemics among cisgender men who have sex with men (MSM) and transgender women (TW) in low- and middle-income countries (LMIC). We compared the effectiveness of respondent-driven sampling (RDS) and venue-based sampling (VBS) for identifying previously undiagnosed HIV infection among MSM and TW in Tijuana, Mexico. METHODS: Between March 2015 and December 2018, we conducted RDS within the social networks of MSM and TW and VBS at venues frequented by MSM and TW to socialize and meet sexual partners. Those reached by RDS/VBS who reported at least 18 years of age, anal sex with MSM or TW, and no previous HIV diagnosis were eligible for HIV testing. RESULTS: Of those screened following recruitment via RDS (N = 1232; 98.6% MSM; 1.3% TW), 60.8% (749/1232) were eligible for HIV testing and 97.5% (730/749) were tested for HIV infection, which led to the identification of 36 newly diagnosed HIV infections (4.9%). Of those screened following recruitment via VBS (N = 2560; 95.2% MSM; 4.6% TW), 56.5% (1446/2560) were eligible for HIV testing and 92.8% (1342/1446) were tested for HIV infection, which led to the identification of 82 newly diagnosed HIV infections (6.1%). The proportion of new HIV diagnoses did not differ by recruitment method (ratio = 0.81, 95% confidence interval: 0.55 to 1.18). Compared to those recruited via RDS, those tested following recruitment via VBS were younger, more likely to identify as gay, and more likely to identify as TW. Compared to those recruited via VBS, those newly diagnosed with HIV infection following recruitment via RDS reported higher levels of internalized stigma and were more likely to report injection drug use and a history of deportation from the United States. CONCLUSIONS: Despite RDS and VBS being equally effective for identifying undiagnosed HIV infection, each recruitment method reached different subgroups of MSM and TW in Tijuana. Our findings suggest that there may be benefits to using both RDS and VBS to increase the identification of previously undiagnosed HIV infection and ultimately support HIV care engagement among MSM and TW in Mexico and other similar LMIC.

Sex Work and High-Risk Anal Human Papillomavirus Infection Among Transgender Women: The Condesa Study.

Purpose: The prevalence of high-risk human papillomavirus (hrHPV) infection among transgender women has been reported to be very high and sexually transmitted infection (STI) prevention strategies have focused on transgender women who engage in sex work. The purpose of our study was to describe hrHPV infection prevalence among a group of transgender women and to explore the differences according to sex work history (SW). Methods: The Condesa Study, an HPV vaccine, and screening study, recruited 207 transgender women without previous HPV vaccination, ages 18-60, from two clinics in Mexico City that provide HIV and transgender health care (May 2018-December 2019). At enrollment, they completed a questionnaire on sociodemographic and sexual behavior data. The hrHPV DNA genotyping was done on self-collected anal samples. Factors associated with hrHPV, stratified by presence or absence of SW, were assessed with multiple logistic regression. Results: A total of 43.5% of participants reported a history of SW. Anal hrHPV prevalence was 62.0% among participants with a history of SW and 52.0% among those without. Overall, 1 in 4 (26.6%) participants were living with HIV. Independent risk factors associated with hrHPV among transgender women with a history of SW were younger age, younger age at first anal intercourse (15-17 years), and greater number of sexual partners in the last 3 months. Among transgender women who had not done SW, greater number of sexual partners in the last 3 months and self-reported STIs were associated with hrHPV. Conclusions: Prevalence of anal infection with hrHPV was high among transgender women. Our results support that other sexual behaviors different from participating in SW contribute to the high prevalence of HPV and that there is an urgent need to include all transgender women in prevention programs for HPV and associated cancers, regardless of SW.

Perceived barriers to pre-exposure prophylaxis use and the role of syndemic factors among female sex workers in the Mexico-United States border region: a latent class analysis.

Female sex workers (FSWs) experience syndemic factors (e.g., polydrug use, hazardous alcohol consumption, client-perpetrated violence, depression, and sexually transmitted infections) that often heighten vulnerability to HIV and limit healthcare utilization. We hypothesized that syndemic factors will limit FSWs' uptake of pre-exposure prophylaxis (PrEP). From 2016 to 2017, 295 HIV-negative FSWs were enrolled in a behavioral HIV prevention trial in Tijuana and Ciudad Juarez, Mexico, underwent STI testing, and completed surveys on syndemic factors and perceived barriers to PrEP use. Syndemic scores (0-5) were calculated by summing syndemic factors. Latent class analysis (LCA) was used to identify homogeneous classes with respect to perceived barriers to PrEP use. We identified four classes: (1) perceived healthcare access barriers (8.3%), (2) perceived financial barriers (18.7%), (3) high level of perceived barriers (19.9%), and (4) low level of perceived barriers (53.0%) to PrEP use. Those experiencing three (adjusted odds ratio [aOR] = 3.63, 95% confidence interval [CI] = 1.24-10.67) and four or five (aOR = 6.30, 95% CI = 1.70-23.35) syndemic factors had a higher odds of membership in the class characterized by a high level of perceived barriers than in the class characterized by a low level of perceived barriers. Addressing syndemic factors may maximize PrEP's impact among FSWs along Mexico's northern border.

A Mixed Methods Analysis of the Venue-Related Social and Structural Context of Drug Use During Sex Among Male Clients of Female Sex Workers in Tijuana, Mexico.

Drug use during sex increases risks for HIV acquisition. Male clients of female sex workers (FSW) represent both a key population at risk for HIV as well as a transmission bridge population. In Tijuana, Mexico, drug use is prevalent and there is a need to understand male clients' drug use during sex with FSW. Characteristics of sex work venues may confer higher risks for drug use, risky sex, and HIV/STI. It is essential to understand the venue-related social and structural factors associated with drug use during sex in order to inform HIV prevention interventions with male clients in this region. We used a Mixed-Methods Sequential Explanatory Design to conduct an enriched examination of drug use during sex among male clients of FSW in Tijuana. Findings from logistic regression analysis showed that drug use during sex was significantly correlated with police harassment (AOR = 4.06, p < .001) and methamphetamine use (AOR = 33.77, p < .001). In-depth interview data provided rich meaning behind and context around the quantitative associations. Social and structural interventions to reduce police harassment, methamphetamine use, and promote condom availability are needed to reduce risks for HIV among male clients of FSW in Tijuana.

People who inject drugs (PWID) and HIV/aids cases in Mexico City: 1987-2015.

BACKGROUND: The purpose of this study is to describe the characteristics of individuals who inject drugs, to explore use trends in the past 25 years, and to review the profile of users of various drugs, both legal and illegal, that have been used intravenously without medical prescription in Mexico City. METHODS: Information was drawn from the Drug Information Reporting System (SRID, 1987-2015) and data from the National Center for the Prevention and Control of HIV/aids (CENSIDA, 1983-2018). SRID is based on two 30-day cross-sectional evaluations carried out during June and November. It has served as an uninterrupted epidemiological surveillance system for 32 years, operating both in health and justice institutions in Mexico City and the metropolitan area. The timely identification of changes in use patterns is regarded as the most consistent tool to track the trajectory of the phenomenon. CENSIDA cases were analyzed based on the number of HIV and aids positive injectable drug users during the same period of time in Mexico City. RESULTS: Cocaine users represented the highest number of cases, with a total of N = 293. Back in 2000, the use of this substance showed a significant increase of up to 50%. In turn, heroine and opiates user trends by sex increased from being almost non-existent in 1987 to 13% in 1994. Results provide evidence of the changes in the number of users over the years, with the largest increases being recorded in 1996 (16.5%), 1999 (17%), and 2010 (13%). CONCLUSIONS: The increase observed in the results coincides with domestic and world political situations that have caused an upturn in the use of some substances over the years. It is not far-fetched to think that in the coming years there will be an increase in the number of individuals who inject drugs due to the high production and availability of heroin in Mexico and the emergence of fentanyl use as indicated by ethnographic research in Mexico City and the deaths linked to its consumption. The latest reports, published in 2018, documented at least five cases of fentanyl users.

Syringe sharing among people who inject drugs in Tijuana: before and after the Global Fund / Uso compartido de jeringas entre las personas que se inyectan drogas en Tijuana: antes y después del Fondo Mundial

Abstract Introduction Needle and syringe programs (NSP) reduce syringe sharing and HIV transmission among people who inject drugs (PWID). However, their effectiveness relies on sufficient individual and population level coverage. In Tijuana, Mexico, the Global Fund (GF) supported NSP during 10/2011-12/2013, but withdrew funds at the end of 2013 following Mexico's re-classification as an upper-middle income country. Objective We tested the hypothesis of higher NSP access and lower receptive syringe sharing among PWID in Tijuana during the GF support period compared to pre-GF initiation and post-GF withdrawal. Method We used data from an ongoing cohort study of PWID in Tijuana (03/2011-10/2015) to implement a segmented regression analysis investigating changes in the self-reported probability of NSP access, reported difficulty in finding sterile syringes and receptive syringe sharing before GF initiation and after GF discontinuation. Results We found a large significant increase in the probability of NSP access (+.07) and decrease in receptive syringe sharing (-.23) right after GF initiation, which continued over the GF period. Subsequently, we found a significant decline in NSP access (-.05) and an increase in receptive syringe sharing (+.02) right after post-GF withdrawal, which continued thereafter. Discussion and conclusion We demonstrated significant temporal changes in NSP access and receptive syringe sharing among PWID in Tijuana after GF initiation and withdrawal consistent with our hypothesis. Coordinated efforts with local authorities are needed to sustain major coverage NSP in settings receiving GF or external aid to guarantee continuity of harm reduction services and prevent reinside in risk behaviors associated with HIV transmission.

Resumen Antecedentes Los programas de intercambio de jeringas (PIJ) reducen la transmisión del VIH entre las personas que se inyectan drogas (PID). Sin embargo, su efectividad depende de una cobertura suficiente a nivel individual y poblacional. En Tijuana, México, el Fondo Mundial (FM) apoyó los PIJ durante 10/2011-12/2013, pero retiró los fondos a fines de 2013. Objetivo Probamos la hipótesis de un mayor acceso a los PIJ y un menor uso receptivo de jeringas compartidas entre las PID en Tijuana durante el período de financiamiento del FM en comparación con el periodo anterior y posterior al FM. Método Usando datos de un estudio de cohorte de PID en Tijuana (03/2011-10/2015), implementamos un análisis de regresión segmentado para investigar cambios en la probabilidad de acceso a las PIJ, la dificultad para encontrar jeringas estériles y el uso receptivo de jeringas compartidas sobre los periodos pre-, durante y post-FM. Resultados Identificamos un aumento en la probabilidad de acceso a PIJ (+.07) y una disminución en el uso de jeringas compartidas (-.23) justo después del inicio del FM, ambos significativos, que se sostuvieron durante el período del FM. Después del retiro del FM, identificamos una disminución en el acceso a PIJ (-.05) y un aumento en el uso de jeringas compartidas (+.02), ambos también significativos. Discusión y conclusión Esfuerzos coordinados con las autoridades locales son necesarios para garantizar una mayor cobertura de los programas de reducción del daño, independientemente de financiamientos externos, para prevenir reincidir en las conductas de riesgo para el VIH en PID.

Development of an evidence-based model of rapid testing, counseling and referral patients with HIV, HVC and other STDs in Mexican addiction treatment centers / Desarrollo de un modelo basado en evidencia de pruebas rápidas, orientación y derivación de pacientes con VIH, VHC y otras ITS en centros mexicanos de tratamiento de adicciones

Abstract Introduction Efforts to identify new cases of HIV, HVC and other STIs, through the application of quick tests, focus on people who inject drugs, without taking into account the fact that the use of alcohol and other drugs of abuse inhibits decision making, increasing the transmission of STIs through risky sexual practices. Accordingly, it is necessary to have detection algorithms that consider people who use multiple drugs to improve the identification of new cases and their subsequent linkage with health services. Objective This paper describes the development process of the OPB-APR model for the detection, counseling and referral of people with HIV and other STIs at addiction treatment centers. Method The procedure is divided into three phases: 1. A literature review to identify the basic concepts of HIV and other STIs, substance use, risky sexual behaviors, quick tests, and specialized psychological counseling; 2. A feasibility study in which a health professional is trained to implement the OPB-APR model; 3. Drafting of the final version. Results The final version of the OPB-APR model was obtained, which describes standardized procedures for detection, counseling and referral to health services. Discussion and conclusions The OPB-APR model aims to strengthen the public health system by increasing the coverage of services for the detection of HIV, HCV and other STIs. The above through the implementation of standardized procedures among specialized and non-specialized health professionals of addiction care centers.

Resumen Introducción Los esfuerzos para la identificación de nuevos casos de VIH, VHC y otras ITS, mediante la aplicación de pruebas rápidas, se centra en personas que se inyectan drogas, sin considerar que el consumo de alcohol y otras drogas de abuso inhiben la toma de decisiones incrementando el riesgo de contagio de ITS durante prácticas sexuales de riesgo. Por este motivo, es necesario contar con algoritmos de detección que consideren a personas con múltiples consumos para incrementar la identificación de nuevos casos y su posterior vinculación a servicios de salud. Objetivo Describir el proceso de desarrollo del modelo OPB-APR para la detección, orientación y referencia de personas con VIH y otras ITS en centros de tratamiento de adicciones. Método El procedimiento se dividió en tres fases: 1. Revisión de literatura para identificar conceptos básicos sobre el VIH y otras ITS, consumo de sustancias, conductas sexuales de riesgo, pruebas rápidas, y orientación psicológica especializada; 2. Estudio de factibilidad en el que se entrenó a profesionales de la saludpara implementar el modelo OPB-APR; 3. Integración de la versión final. Resultados Se obtuvo la versión final del modelo OPB-APR el cual describe procedimientos estandarizados para la detección, orientación y referencia a servicios de salud. Discusión y conclusión El modelo OPB-APR pretende fortalecer al sistema público de salud al incrementar la cobertura de servicios para la detección del VIH, VHC y otras ITS. Lo anterior mediante la implementación de procedimientos estandarizados entre los profesionales de la salud especializados y no especializados de centros para la atención de adicciones.
