Name TB treatment success rate (number and % of new smear positive TB cases successfully treated among registered smear positive TB patients (MDG 6.10.2)
Definition The proportion of new smear-positive TB cases registered under DOTS in a given year that successfully completed treatment, whether with bacteriologic evidence of success (“cured”) or without (“treatment completed”). At the end of treatment, each patient is assigned one of the following six mutually exclusive treatment outcomes: cured; completed; died; failed; defaulted; and transferred out with outcome unknown. The proportions of cases assigned to these outcomes, plus any additional cases registered for treatment but not assigned to an outcome, add up to 100% of cases registered.
Calculation/Formula "Treatment success rates are calculated from cohort data (outcomes in registered patients) as the proportion of new smear-positive TB cases registered under DOTS in a given year that successfully completed treatment, whether with (“cured”) or without (“treatment completed”) bacteriologic evidence of success"
Assumptions Treatment success rates can be low for a number of reasons. Several factors affect the likelihood of treatment success, including the severity of disease (often related to the delay between onset of disease and the start of treatment), HIV infection, drug resistance, malnutrition and the support provided to the patient to ensure that he or she completes treatment. Even where treatment is of high quality, reported treatment success rates will only be high when the routine information system is also functioning well. The treatment success rate will be affected if the outcome of treatment is not recorded for all patients (including those who transfer from one treatment facility to another).Where treatment success rates are low, the cause of the problem can only be identified by determining which of the unfavourable treatment outcomes is most common.
Purpose/Rationale To reduce TB related morbidity and mortality, achieve Stop TB Partnership targets and contribute towards the achievement of the Millennium Development Goals. Rationale: Evaluation of successful treatment outcomes of new smear positive pulmonary TB patients is used to determine the quality and effectiveness of DOTS implementation at all levels. Internationally recommended outcome indicator, with international and regional targets; The international target is to successfully treat at least 85% of new sputum smear positive TB cases; The regional target is to move beyond 85%
