PP116 Health utilities and neglected conditions: A Chagas disease study.

Abstract
Introduction:

Chagas disease (ChD), also known as American trypanosomiasis, is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. About 6 to 7 million people worldwide are estimated to be infected, most in Latin America. Health-related quality of life (HRQoL) and utility measures are still poorly employed for assessment of ChD lifetime impairments. Brazilian HRQoL published data showed that the cardiac subgroup of patients have worse scores than other ChD chronic groups. For the time being, utility scores are not available yet for the ChD population. The present study aims to assess quality of life (QoL), as utility scores, of patients with chronic Chagas Disease.

Methods:

This is a cross-sectional study. Data were collected from 183 outpatients with chronic ChD in a reference center in Brazil. Information pertaining to sociodemographics, clinical status, and quality of life were collected using self-administered questionnaires. Utilities were obtained by the European Quality of Life – 5 Dimensions (EQ-5D) questionnaire. Comparisons were made between clinical subtypes and population normative values. Continuous variables were compared using t-test or ANOVA, and categorical variables were compared using Chi-square test. Associations between QoL and patient characteristics stratified by demographics, clinical status were identified by linear regression models.

Results:

Most subjects were female (61 percent). The average age of men was 53.3 years and women 56.6. When analyzing the EQ-5D utility scores, it was observed that the results were lower for cardiac patients (0.610–95% CI 0.582–0.638) in comparison to indeterminate form patients (0.659–0.632–0.687). When comparing patients with the general population of the same age and sex, patients with ChD showed lower utility scores than normative values (0.624–95% CI 0.596–0.652).

Conclusions:

Chronic ChD causes a negative impact on quality of life, physical functioning, as well as psychosocial function, with the impairment becoming worse in cardiac patients.
