The increase in the burden of multidrug-resistant tuberculosis (MDR-TB) is a matter of grave concern. The present study was undertaken to describe MDR-TB treatment outcome trends in Delhi and their epidemiological correlates, to assess the adequacy of treatment records and to also generate evidence towards influencing and improving practices related to the MDR-TB control programme.
A retrospective record-based study (2009-2014) was conducted in three major drug resistance TB treatment centres of Delhi. Treatment outcomes and adverse effects were extracted from the existing programme records including patients’ treatment cards and laboratory registers.
A total of 2958 MDR-TB patients were identified from the treatment cards, of whom 1749 (59.12%) were males. The mean (±standard deviation) age was 30.56±13.5 years. Favourable treatment outcomes were reported in 1371 (53.28%) patients, but they showed a declining trend during the period of observation. On binomial logistic regression analysis, patients with age ≥35 yr, male sex and undernourishment (body mass index <18.5) at the time of treatment initiation had a significantly increased likelihood of unfavourable MDR-TB treatment outcome (P <0.001).
The study showed an increasing burden of MDR-TB patients, especially in the young population with increased risk of transmission posing a major challenge in achieving TB elimination targets.
