title: Tuberculosis mortality trends in Delhi after implementation of RNTCP.
abstract: OBJECTIVE
  To study the impact of Revised National TB Control Programme on mortality among tuberculosis patients in Delhi and to correlate mortality trends with programme indicators.
  
  
  METHODS
  Record based evaluation of mortality trends from TB registers of all chest clinics of Delhi after implementation of Revised National TB Control Programme.
  
  
  RESULTS
  The study showed a statistically significant decline in tuberculosis mortality among new smear positive cases after the implementation of Revised National TB Control Programme (z = 4.478 p < 0.05). The mortality among new smear negative and extra pulmonary cases also showed reduction, though not statistically significant.
  
  
  CONCLUSIONS
  Mortality due to tuberculosis has been considerably reduced in Delhi over the years with the Revised National TB Control Programme implementation since 1997.
