SETTING: Tuberculosis clinic in a teaching hospital run by the social security system, Istanbul, Turkey.

OBJECTIVE: To determine risk factors associated with treatment adherence.

DESIGN: Seven hundred and seventeen patients who commenced treatment for tuberculosis in our clinic from May 1991 to May 1997 were evaluated retrospectively with respect to treatment adherence. Factors with an effect on treatment adherence were investigated.

RESULTS: Sputum conversion was achieved in 88.9% of the cases within the first 2 months of treatment. Seven patients died during treatment; of the 710 patients remaining, 106 (14.9%) were non-adherent. This rate decreased from 34.4% in 1991 to 2.0% in 1997. In multivariate logistic regression analysis, only previous treatment history for tuberculosis was related to non-adherence; treatment adherence rate in new cases was 88.9%, while it was 66.7% in previously treated cases (P < 0.001).

CONCLUSION: In new cases, a treatment adherence rate of 88.9% can be considered satisfactory. However, in previously treated cases, an adherence rate of 66.4% must be considered unsatisfactory. Previously treated cases in particular should therefore receive directly observed treatment.
