Abstract

Introduction: Tuberculosis is historically associated with poverty, generating costs that can influence treatment. Considering the impact of the costs of illness, the importance of adapting the instrument is highlighted.

Objective: To adapt transculturally to Brazilian Portuguese the instrument Tool to Estimate Patient's Costs.

Methods: Study of the type transcultural adaptation of instrument. The translation followed the criteria described by Herdman, 1998, in order to preserve functional equivalence as much as possible. The questionnaire with cross-cultural adaptation was applied to 77 patients, with at least one full month of treatment for the disease.

Results: Instrument was shown with Cronbach Alpha above 0.71 constituting a good tool for measuring the costs of the disease, being necessary modifications.

Conclusions: This study suggests the creation of an instrument adapted for the treatment of TB in Brazil, for the evaluation of costs with the illness by tuberculosis.

Resumen

Introducción: La tuberculosis está históricamente asociada con la pobreza, generando costes que pueden influir en el tratamiento. Considerando el impacto de estas cuantías de la enfermedad, se destaca la importancia de la adaptación del instrumento.

Objetivo: Adaptar transculturalmente al portugués brasileño la herramienta "Tool to Estimate Patient's Costs".

Métodos: Estudio del tipo adaptación transcultural del instrumento. La traducción siguió los criterios descritos por Herdman (1998), para preservar al máximo la equivalencia funcional. El cuestionario, con adaptación transcultural, fue aplicado en 77 pacientes, con al menos un mes completo de tratamiento para la enfermedad.

Resultados: El instrumento presentó resultado de 0,71 con el alfa de Cronbach, constituyéndose en una buena herramienta para medir los costes de la enfermedad, siendo necesarias modificaciones.

Conclusiones: Este estudio sugiere la creación de un instrumento adaptado para el tratamiento de la TB en Brasil, para la evaluación de los costes con la enfermedad por tuberculosis.
