Tratamiento supervisado por video VDOT en pacientes con tuberculosis pulmonar de un Centro de Salud de Lima. Estudio piloto / Treatment supervised by video (VDOT) in patients with tuberculosis from a Health Center in Lima. Pilot study

RESUMEN Objetivo: Describir las características de la implementación del tratamiento supervisado por video (VDOT) en pacientes con tuberculosis en un establecimiento de salud de la seguridad social del primer nivel de atención en Perú (EsSalud). Material y métodos: Estudio observacional, descriptivo. Los pacientes fueron enrolados de forma prospectiva de 18/09/2018 al 24/09/2019. Ocho de los nueve pacientes seguidos completaron el tratamiento VDOT. Un paciente fue transferido a otro establecimiento de salud antes de terminar el seguimiento. Una enfermera entrenada de Socios En Salud gestionó las 727 video llamadas. Resultados: Se obtuvo una adherencia al tratamiento del 100%. Conclusiones: La estrategia VDOT sería una modalidad alternativa útil en pacientes con tuberculosis sensible.

SUMMARY Objective: To report the characteristics of the implementation process of the video supervised treatment (VST) of patients with pulmonary tuberculosis in a first level health care center of the Social Security in Peru. Methods: An observational study was carried-out including patients enrolled from 18/09/2018 to 24/09/2019. Eight out of ninepatients completed the VST, one patient was transferred to other institution before finishing treatment. One nurse trained at Partners in Health arranged the 727 video calls. Results: adherence to treatment was 100%. Conclusions: VST may be a useful alternative for patients with drug sensitive tuberculosis.

Closing delivery gaps in the treatment of tuberculosis infection: Lessons from implementation research in Peru.

BACKGROUND: Targeted testing and treatment of TB infection to prevent disease is a pillar of TB elimination. Despite recent global commitments to greatly expand access to preventive treatment for TB infection, there remains a lack of research on how best to expand preventive treatment programs in settings with high TB burdens. METHODS: We conducted implementation research in Lima, Peru, around a multifaceted intervention to deliver TB preventive treatment to close contacts of all ages, health care workers, and people in congregate settings. Key interventions included use of the interferon gamma release assay (IGRA), specialist support for generalist physicians at primary-level health facilities, and treatment support by community health workers. We applied a convergent mixed methods approach to evaluate feasibility and acceptability based on a care cascade framework. FINDINGS: During April 2019-January 2020, we enrolled 1,002 household contacts, 148 non-household contacts, 107 residents and staff of congregate settings, and 357 health care workers. Cumulative completion of the TB preventive care cascade was 34% for contacts <5 years old, 28% for contacts 5-19 years old, 18% for contacts ≥20 years old, 0% for people in congregate settings, and 4% of health care workers. IGRA testing was acceptable to adults exposed to TB. Preventive treatment was acceptable to contacts, but less acceptable to physicians, who frequently had doubts about prescribing preventive treatment for adults. Community-based treatment support was both acceptable and feasible, and periodic home-visits or calls were identified as facilitators of adherence. CONCLUSIONS: We attempted to close the gap in TB preventive treatment in Peru by expanding preventive services to adult contacts and other risk groups. While suboptimal, care cascade completion for adult contacts was consistent with what has been observed in high-income settings. The major losses in the care cascade occurred in completing evaluations and having doctors prescribe preventive treatment.

Community-based participatory design of a community health worker breast cancer training intervention for South Florida Latinx farmworkers.

OBJECTIVE: Community health worker (CHW)-led education is an important strategy to increase awareness and access to breast cancer screening in medically-underserved communities. This study aimed to develop a context-specific, culturally-appropriate training intervention for South Florida CHWs to educate Latinx immigrant farmworkers on breast cancer and early detection. METHODS: A community-based participatory research (CBPR) study, conducted 2017-2019, informed the design of a training curriculum for CHWs and educational dissemination materials. Twenty-two CHWs were trained and knowledge gains were measuring using a one-group pre-and post-test design. Triangulated evaluation consisted of field observations of CHW-client interactions, CHW self-reports, and rapid assessment surveys of community members. RESULTS: A community stakeholder-informed breast cancer training curriculum resulted in significant, sustained breast cancer knowledge gains among CHWs when comparing pre-, post-, and 4-6 month post-training follow-up test scores. Field observations of educational material dissemination, CHW self-reported evaluations, and community rapid assessment surveys at three health fairs demonstrated this was an effective strategy to engage female Latinx farmworkers in breast cancer education. CONCLUSIONS: Community and key stakeholder participation in the development of a breast cancer educational intervention allowed for tailored design priorities around knowledge-based content, comprehensiveness, relevance, appropriateness, and ease of dissemination to community members. This model of participatory CHW training intervention design can enable future train-the-trainer approaches to disseminate and scale-up evidence-based health education interventions.

Self-identity, lived experiences, and challenges of breast, cervical, and prostate cancer survivorship in Mexico: a qualitative study.

BACKGROUND: Qualitative research on cancer patients' survivor-identity and lived experiences in low- and middle-income countries is scarce. Our study aimed at exploring the concept and experience of survivorship for Mexicans living with breast, cervical, and prostate cancer. METHODS: We conducted a qualitative study in Mexico City, Morelos, Nuevo León, and Puebla. The participants were breast, cervical, and prostate cancer patients ≥18 years of age with completed primary cancer treatment. Data were collected via in-depth interviews and analyzed using an inductive thematic approach. RESULTS: The study included 22 participants with a history of breast, 20 cervical, and 18 prostate cancer. Participants accepted the term "cancer survivor" as a literal interpretation of being alive, medical confirmation of treatment completion, or achievement of a clinical result possibly indicative of cure. The majority of respondents perceived that the future is out of their control and under God's will. They linked cure to divine intervention and did not demonstrate the sense of empowerment that is often associated with the survivorship term. The principal themes of their narratives encompass: 1) adverse physical and sexual experiences; 2) emotional problems; 3) cancer-related stigma; 4) challenges to obtaining health-related information; 5) financial hardship; and 6) experience of strengthening family ties in order to provide them with support. In addition, women with breast cancer reported distress caused by changes in body image and positive experience with support groups. CONCLUSION: In Mexico, cancer patients report complex survivorship experiences that demand post-treatment follow-up and support. There is the need to implement comprehensive, culturally-relevant survivorship programs focused on emotional, informational, and in-kind support and empowerment of cancer patients.
