ABSTRACT
INTRODUCTION: In the context of the COVID-19 pandemic, information on factors associated with adherence to antituberculosis treatment in areas with high prevalence of tuberculosis is scarce. OBJETIVE: To evaluate whether there is an association between social support, concern about COVID-19 infection and knowledge about tuberculosis, and non-adherence to antituberculosis treatment. MATERIALS AND METHODOS: A cross-sectional study was carried out on patients under antituberculosis treatment, from January to March, 2022, in centers located in areas with a high prevalence of tuberculosis in Lima. We used the Morisky Green-Levine questionnaire to assess adherence to treatment as the dependent variable; the independent variables were evaluated using the Medical Outcomes Study Social Support Survey for perceived social support and concern about COVID-19 infection, and the Battle Test to assess patients' knowledge about their disease. We used Poisson regression with robust variance to evaluate the association between the independent variables and the dependent one. RESULTS: Out of 101 participants (73.3% male with an average age of 35.1 ± 16 years), 51.5% were non-adherent to antituberculosis treatment. Medium or high level of concern about getting COVID-19 was associated with a higher prevalence of non-adherence to treatment (odds ratio: 1.68; 95 % confidence interval: 1.09-2.57) (adjusted for considered confounding variables). CONCLUSIONS: Non-adherence is a frequent condition among patients living in an area with a high prevalence of tuberculosis in Lima, especially among those with a higher concern for COVID-19 infection.
Introducción: En el contexto de la pandemia por la COVID-19 es escasa la información de factores asociados al cumplimiento del tratamiento antituberculoso en las zonas de alta prevalencia de tuberculosis. Objetivo: Evaluar si existe asociación entre el apoyo social, la preocupación por el contagio de COVID-19 y el conocimiento de la tuberculosis, frente al incumplimiento del tratamiento antituberculoso. Materiales y métodos: Se trata de un estudio transversal de pacientes en tratamiento antituberculoso durante los meses de enero a marzo del 2022 en centros ubicados en áreas de alta prevalencia de tuberculosis en Lima. Se utilizó el cuestionario de Morisky Green-Levine para evaluar el cumplimiento del tratamiento como variable dependiente; las variables independientes se evaluaron usando el Medical Outcomes Study Social Support Survey para determinar el apoyo social percibido y la preocupación por la infección de COVID-19, y el test de Batalla para evaluar el conocimiento del paciente sobre su enfermedad. Se utilizó la regresión de Poisson con varianza robusta para determinar la asociación entre las variables. Resultados: De un total de 101 participantes (73,3 % hombres y edad media 35,1 ± 16 años), el 51,5 % no observaron el tratamiento antituberculoso. El nivel de preocupación medio o alto de contagiarse y desarrollar COVID-19 se asoció con una mayor prevalencia de incumplimiento del tratamiento (razón de prevalencia: 1,68; intervalo de confianza del 95 %: 1,09-2,57) (ajustada por las variables de confusión consideradas). Conclusiones: El incumplimiento del tratamiento antituberculoso es una condición frecuente entre los pacientes de una zona de alta prevalencia de tuberculosis en Lima especialmente entre aquellos con mayor preocupación al contagio por el virus de SARSCoV-2, causante de la COVID-19.

OBJECTIVES: In developing nations, the use of operational parameters (OPs) in the prediction of clinical care represents a missed opportunity to enhance the care process. We modeled the impact of multiple measurements of antiretroviral treatment (ART) adherence on antiretroviral treatment outcomes in Peru. DESIGN AND METHODS: Retrospective cohort study including ART naïve, non-pregnant, adults initiating therapy at Hospital Nacional Cayetano Heredia, Lima-Peru (2006-2010). Three OPs were defined: 1) Medication possession ratio (MPR): days with antiretrovirals dispensed/days on first-line therapy; 2) Laboratory monitory constancy (LMC): proportion of 6 months intervals with ≥1 viral load or CD4 reported; 3) Clinic visit constancy (CVC): proportion of 6 months intervals with ≥1 clinic visit. Three multi-variable Cox proportional hazard (PH) models (one per OP) were fit for (1) time of first-line ART persistence and (2) time to second-line virologic failure. All models were adjusted for socio-demographic, clinical and laboratory variables. RESULTS: 856 patients were included in first-line persistence analyses, median age was 35.6 years [29.4-42.9] and most were male (624; 73%). In multivariable PH models, MPR (per 10% increase HR=0.66; 95%CI=0.61-0.71) and LMC (per 10% increase 0.83; 0.71-0.96) were associated with prolonged time on first-line therapies. Among 79 individuals included in time to second-line virologic failure analyses, MPR was the only OP independently associated with prolonged time to second-line virologic failure (per 10% increase 0.88; 0.77-0.99). CONCLUSIONS: The capture and utilization of program level parameters such as MPR can provide valuable insight into patient-level treatment outcomes.
