ABSTRACT Objective To identify factors associated with loss to follow-up in Tuberculosis (TB) treatment, including patients' level of knowledge regarding treatment of this disease. Methods 42 loss to follow-up cases and 84 control cases that were finishing the sixth month of their first treatment for tuberculosis were selected for this study. Primary data were gathered through interviews, while secondary data were obtained from the notification form of the disease, between December 2011 and April 2012. Factors associated with loss to follow-up were analyzed by means of a conditional logistic regression multivariate model for matched case-control groups. Results No significant differences were observed between loss to follow-up cases and controls regarding socioeconomic factors, lifestyle, clinical condition, treatment-related behaviors and the access of patients to sources of information on TB. In the regression multivariate analysis, significant associations with retreatment after loss to follow-up that were detected include: scarce knowledge on tuberculosis, lack of adherence to consultation during the current treatment, noncompliance with follow-up consultation deadline, smoking and HIV negative. Conclusion When compared to controls, cases undergoing TB retreatment after loss to follow-up have less knowledge on the disease, which is a sign for the professionals responsible for health education of the need to invest more time and efforts in activities that help the patient understand the disease and its treatment, as well as to have higher levels of adherence. In addition, noncompliance with the follow-up consultation deadline, failure to attend consultations during the current treatment and smoking are also factors that may be influenced by poor knowledge on the disease, which leads to the treatment loss to follow-up.(AU)
RESUMEN Objetivo Identificar los factores asociados con la pérdida del seguimiento en el tratamiento de la tuberculosis (TB), incluyendo el nivel de conocimiento de los pacientes sobre el tratamiento de esta enfermedad. Métodos Se seleccionaron 42 casos de pérdida de seguimiento y 84 controles que se encontraban terminando el sexto mes de su primer tratamiento contra la TB. Los datos primarios fueron recolectados mediante entrevistas, mientras que los secundarios, a partir del formulario de notificación de la enfermedad, entre diciembre de 2011 y abril de 2012. Se utilizó modelo multivariado de regresión logística condicional para analizar los factores asociados con la pérdida del seguimiento entre grupos de casos y controles emparejados. Resultados No hay diferencias significativas entre los casos y controles en cuanto a factores socioeconómicos, estilos de vida, condición clínica, comportamientos relacionados con el tratamiento de la enfermedad, así como el acceso a fuentes de información sobre tuberculosis.
