title: Impact of national consultants on successful expansion of effective tuberculosis control in India.
abstract: METHODS
  India, during a period of rapid expansion of DOTS services. DOTS expansion has been slow in many countries.
  
  
  OBJECTIVE
  To document use of consultants to expand DOTS effectively.
  
  
  METHODS
  Staff were contracted to monitor DOTS expansion and implementation. To estimate the impact of these staff, we compared areas with and without consultants, and individual areas before and after consultants were assigned. Consultants were preferentially assigned to the more difficult areas; the temporary absence of consultants reflected non-availability of candidates.
  
  
  RESULTS
  Areas with consultants met pre-defined criteria and began DOTS service delivery faster (median 9 vs. 18 months of preparation) than areas without consultants. Rates of sputum conversion (87% vs. 83%, P < 0.001) and treatment success (83% vs. 78%, P < 0.001) were significantly higher in areas with consultants present.
  
  
  CONCLUSIONS
  Assignment of consultants resulted in much more rapid implementation of the DOTS strategy, and better quality performance. Continued effective performance in these areas will rely on many factors, but the need for consultants appears to be decreasing, suggesting that they have provided sustainable improvements. The effectiveness of local consultants may have important implications for efforts to scale up public health interventions for tuberculosis, malaria, AIDS and other diseases in developing countries.
