[Evaluation of the Program for the Prevention and Control of Tuberculosis during the period January 1993 - June 1996]

In 1992 a Technical Commission was formed in Navarra with the participation of different specialists who drew up the Program of Vigilance and Control of Tuberculosis. We present the results of the evaluation of this program for the period from January 1993 to June 1996. In the 3.5 years of the study, 419 cases of tuberculosis were found, 317 belonging to respiratory forms and 102 to extra-respiratory forms. The annual rate of incidence of total tuberculosis, 22.8 cases per 100,000 inhabitants observed in Navarra, is the lowest of those registered at the level of the Autonomous Communities according to the TIR study of the SEPAR (acronym for Spanish Society of Pneumology and Thoracic Surgery) in 1996, and the second lowest, after Castilla-La Mancha, according to the multicentric study of the National Centre of Epidemiology. In Navarra the highest rates of incidence are produced in those over 65 years of age, following the pattern observed in the more developed countries. 13.9% of the patients with respiratory tuberculosis showed co-infection by HIV, and besides more than 90% of these were users of intravenous drugs. The percentage of immigrants, prisoners and the destitute observed in the Navarra series is lower than that found in areas such as Madrid, Barcelona or Zaragoza. 91% of the cases of respiratory tuberculosis showed bacteriological confirmation and 98% of the cases were diagnosed and treated in specialised care. Outstanding were the high follow-up of the cases until discharge and the high percentage of cures achieved, some 85.4%.
