ABSTRACT
SETTING: A novel patient-centered tuberculosis (TB) treatment delivery program, 'Sputnik', was introduced for patients at high risk of treatment default in Tomsk City, Russian Federation. OBJECTIVE: To assess the effects of the Sputnik intervention on patient default rates. DESIGN: We analyzed the characteristics of patients referred to the program, treatment adherence of Sputnik program enrollees before and during the intervention, and final outcomes for all patients referred to the Sputnik program. RESULTS: For patients continuing their existing regimens after referral to the program (n = 46), mean adherence to treatment increased by 56% (from 52% of prescribed doses prior to enrolment to 81%). For patients initiating new regimens after referral ( n = 5), mean adherence was 83%. Mean adherence for patients with multidrug-resistant TB (MDR-TB; n = 38) was 79% and for all others (n = 13) it was 89%. The cure rate was 71.1% for patients with MDR-TB, 60% for all others and 68% in the program overall. CONCLUSION: The Sputnik intervention was successful in reducing rates of treatment default among patients at high risk for non-adherence.
