ABSTRACT
Background & objectives: This study was aimed at estimating the proportion among sputum smear-positive tuberculosis (TB) patients diagnosed at a tertiary care centre in India, who did not undergo universal drug-susceptibility testing (UDST), assessing the sociodemographic and morbidity-related factors associated with it, ascertaining the reasons for not getting tested and estimating the proportion with any drug resistance (DR). Methods: TB Notification Register and TB Laboratory Register, maintained in Designated Microscopy Centre and Intermediate Research Laboratory, respectively were used to obtain the patient details and information regarding UDST and DR-TB status. Under UDST, the TB patients had undergone rapid molecular tests to check for any DR. TB patients who dropped out of this strategy (those who did not submit a sputum sample for DR testing even after being instructed) were telephonically contacted and asked regarding reasons for not getting themselves tested. Results: Of the 215 patients, 74 [34.4%, 95% confidence interval (CI): 28.1-41.2] did not undergo UDST. Of these 74 participants, 60 per cent reported the reason that they were not informed regarding the drug-susceptibility test. Among the 141 patients who underwent UDST, six (4.3%, 95% CI: 1.58-9.03) had DR. Non-UDST patients were significantly more in percentage among TB patients who were aged <30 years (adjusted prevalence ratio 2.36; 95% CI: 1.19-4.68) compared to >60 years. Interpretation & conclusions: The present findings point towards a need to sensitize healthcare workers and TB patients to improve UDST.
ABSTRACT
Objectives: The coronavirus disease 2019 (COVID-19) pandemic affected routine healthcare services across all spectra, and tuberculosis (TB) care under the National Tuberculosis Elimination Program have been affected the most. However, evidence available at the community level is minimal. The clinical features, care cascade pathway, and treatment outcomes of TB patients pre- and during/post-COVID-19 pandemic lockdown in a rural community health block in northern India were assessed and compared.Materials and Methods: This was a retrospective cohort study that included all patients diagnosed with TB and initiated treatment under programmatic settings between January 1 and June 30, 2020, in a rural TB unit in northern India. The periods from January 1 to March 23 and March 24 to June 30 were marked as pre-lockdown and during/post-lockdown, respectively.Results: A total of 103 patients were diagnosed and treated for TB during the study period. A significantly higher proportion of pulmonary TB cases were reported during/post-lockdown (43, 82.7%) compared to that pre-lockdown (32, 62.7%), and a higher diagnostic delay was noted during/post-lockdown (35, 81.4%). Through adjusted analysis, patients diagnosed during/post-lockdown period (adjusted risk ratio [aRR], 0.85; 95% confidence interval [CI], 0.73–0.98) and previously treated (aRR, 0.77; 95% CI, 0.60–0.995) had significantly lower favorable treatment outcomes.Conclusions: The symptom and disease (pulmonary/extrapulmonary) pattern have changed during/post-lockdown. The care cascade delays are still high among TB patients, irrespective of the lockdown status. Lockdown had a significant adverse impact on the outcomes of TB treatment.
