BackgroundDaily directly-observed therapy (DOT) is recommended for rifampicin-resistant tuberculosis (RR-TB) patients throughout treatment. We assessed the impact of self-administered treatment (SAT) in a South African township with high rates of RR-TB and HIV.MethodsCommunity-supported SAT for patients who completed the intensive phase was piloted in five primary care clinics in Khayelitsha. We compared final treatment outcomes among RR-TB patients initiating treatment before (standard-of-care (SOC)-cohort, January 2010-July 2013) and after the implementation of the pilot (SAT-cohort, January 2012-December 2014). All patients with outcomes before January 1, 2017 were considered in the analysis of outcomes.ResultsOne-hundred-eighteen patients in the SOC-cohort and 174 patients in the SAT-cohort had final RR-TB treatment outcomes; 70% and 73% were HIV-co-infected, respectively. The proportion of patients with a final outcome of loss to follow-up (LTFU) did not differ whether treated in the SOC (25/118, 21.2%) or SAT-cohort (31/174, 17.8%) (P = 0.47). There were no significant differences in the time to 24-month LTFU among HIV-infected and uninfected patients (HR 0.90, 95% CI: 0.51–1.6, P = 0.71), or among patients enrolled in the SOC-cohort versus the SAT-cohort (HR 0.83, 95% CI: 0.49–1.4, P = 0.50) who received at least 6-months of RR-TB treatment.ConclusionThe introduction of SAT during the continuation phase of RR-TB treatment does not adversely affect final RR-TB treatment outcomes in a high TB and HIV-burden setting. This differentiated, patient-centred model of care could be considered in RR-TB programmes to decrease the burden of DOT on patients and health facilities.
An intervention based on early tracing of patients who interrupt treatment, peer-delivered counselling and individualised management plans by a multidisciplinary team was considered a beneficial and acceptable model to support patients at risk of LTFU from DR-TB treatment.
Drug-resistant tuberculosis (DR-TB), defined as TB with at least rifampicin resistance, is increasing in prevalence and incidence worldwide. [1] South Africa (SA) has reported some of the highest numbers of DR-TB cases globally: in 2012 alone there were 14 161 laboratorynotified cases of multidrug-resistant TB (MDR-TB) and 1 545 cases of extensively drug-resistant TB (XDR-TB). [2] Regimens available for DR-TB are expensive, toxic, and require a minimum treatment duration of 20 months. In addition, currently available medications often cause multiple side-effects that impact on patients' ability to maintain their usual daily activities. [3] The burden of treatment regimens contributes to poor DR-TB programme outcomes, including high rates of loss from treatment (LFT) and stagnant treatment success rates. A study conducted in the Western Cape Province, SA, found an LFT rate of 27%, which is comparable to LFT rates observed in other DR-TB treatment cohorts in SA. [4] National Department of Health (NDoH) data from 2012 reflect a 40% treatment success rate for MDR-TB and less than 20% treatment success for XDR-TB. [2] It is imperative that strategies to provide structured patient support are developed and implemented to promote retention in care. Setting Khayelitsha, a township in the Western Cape, is home to approximately 500 000 people and has one of the highest rates of
