OBJECTIVES: To determine the effectiveness of strategies used to promote adherence to anti-tuberculosis treatment. SEARCH STRATEGY: MEDLINE 1966-1996 (August), Cochrane Collaboration Trials Registers (October 1996), LILACS 1982-1996 (September); reference lists in articles on adherence, contact with experts in the fields of TB and adherence research. SELECTION CRITERIA: Randomised or pseudo-randomised controlled trials of interventions to promote compliance with curative or preventive chemotherapy for TB, with at least one measure of adherence. DATA COLLECTION AND ANALYSIS: Data on study methods, participants, interventions and outcomes were collected for each study and methodological quality was assessed. Estimates of effect were assessed for categorical outcomes using the Peto odds ratio, with 95% confidence intervals. MAIN RESULTS: Strategies found to be of benefit were reminder cards sent to defaulters, assistance of patients by lay health workers, monetary incentives offered to patients, and increased supervision of TB clinic staff. It is not possible to determine from current trials whether health education by itself leads to better adherence to treatment. Even though directly-observed therapy (DOT) is widely advocated as the most cost-effective means of ensuring completion of TB treatment, no completed trials could be found which confirm or refute this view. CONCLUSIONS: RCT evidence exists that certain strategies improve adherence to anti-tuberculous therapy, and these should be adopted into clinical practice depending on their appropriateness to practice circumstances. Further innovations should be tested to find solutions that will be useful in low income countries. Randomised trials evaluating the independent effects of directly-observed therapy (DOT) are awaited.
