Factors determining compliance with tuberculosis treatment in an urban environment, Tamatave, Madagascar.

SETTING

Patient compliance remains one of the main obstacles that need to be overcome by tuberculosis control programmes, in the developing world as well as in industrialised countries. A better understanding of the various factors accounting for treatment default could help to achieve better compliance from patients.

OBJECTIVES

To increase the understanding of the determining factors of default in an urban environment where medical facilities are accessible. Different kinds of determinants were studied: objective socio-demographic factors, subjective psychological factors, attitudes and behaviour of patients in relation to chemotherapy, quality of relationships with the medical staff, knowledge and attitudes regarding tuberculosis.

DESIGN

Risk factors for default were assessed by a retrospective case-control study in a sample of 38 patients who had not completed treatment for pulmonary tuberculosis, compared with 111 controls who had completed treatment under comparable conditions.

RESULTS

Default appears to be significantly linked to transportation time, the sex of the patient, patient information and the quality of communication between patients and health workers. False addresses given by patients are both a methodological bias and a risk factor for future default.

CONCLUSION

Improved communication skills and attention from the medical staff could encourage more patients to complete their TB treatment.
