The community-based MDR-TB care (CBMDR-TBC) project was implemented in 2015 by The Union in collaboration with national TB programme (NTP) in 33 townships of upper Myanmar to improve treatment outcomes among patients with MDR-TB registered under NTP. They received community-based support through the project staff, in addition to the routine domiciliary care provided by NTP staff. Each project township had a project nurse exclusively for MDR-TB and a community volunteer who provided evening directly observed therapy (in addition to morning directly observed therapy by NTP). To determine the effect of CBMDR-TBC project on death and unfavourable outcomes during the intensive phase of MDR-TB treatment. In this cohort study involving record review, all patients diagnosed with MDR-TB between January 2015 and June 2016 in project townships and initiated on treatment till 31 Dec 2016 were included. CBMDR-TBC status was categorized as "receiving support" if project initiation in patient's township was before treatment initiation, "receiving partial support" if project initiation was after treatment initiation, and "not receiving support" if project initiation was after intensive phase treatment outcome declaration. Time to event analysis (censored on 10 April 2017) and cox regression was done. Of 261 patients initiated on treatment, death and unfavourable outcomes were accounted for 13% and 21% among "receiving support (n = 163)", 3% and 24% among "receiving partial support (n = 75)" and 13% and 26% among "not receiving support (n = 23)" respectively. After adjusting for other potential confounders, the association between CBMDR-TBC and unfavourable outcomes was not statistically significant. However, when compared to "not receiving support", those "receiving support" and "receiving partial support" had 20% [aHR (0.95 CI: 0.8 (0.2-3.1)] and 90% lower hazard [aHR (0.95 CI: 0.1 (0.02-0.9)] of death, respectively. This was intriguing. Implementation of CBMDR-TBC coincided with implementation of decentralized MDR-TB centers at district level. Hence, patients that would have generally not accessed MDR-TB treatment before decentralization also started receiving treatment and were also included under CBMDR-TBC "received support" group. These patients could possibly be expected to sicker at treatment initiation than patients in other CBMDR-TBC groups. This could be the possible reason for nullifying the effect of CBMDR-TBC in "receiving support" group and therefore similar
