Abstract

Cost of five different investigative procedures in a survey situation, based on different orderings of examinations, X-ray chest and sputum examination along with symptoms suggestive of pulmonary tuberculosis, have been calculated under certain TXU motions. The esti”1 are subject to variation with any change in the assumptions. The objective here was to pro comparison of the five investigative procedures in a survey situation by taking un auxiliary example rather than precise estimation of cost. The main criterion for comparing the individual investigative procedures is the cost per bacillary case identified by an individual procedure. The study reveals that, while carrying out a prevalence survey through an investigative procedure, persons eligible for sputum examination should be offered microscopy and culture examination of sputum specimens because it is more efficacious and cost per bacillary case identified is also lower as coin-pared to microscopy examination of sputum specimens. In cities, under such a plan, cost per bacillary case identified is the lowest under investigative procedure TV and cost per bacillary case identified under procedure II is only slightly more. In towns/villages, cost per bacillary case identified is the lowest under procedure II and cost per bacillary case identified under procedure IV is only slightly more. Therefore any of these investigative procedure can be adopted for carrying out a tuberculosis prevalence survey according to situation. It is suggested that procedure IV should be adopted if mobile X-ray unit is available and whenever the X—ray unit goes out of order, procedure II can be followed as an alternative. It is suggested that the work load of various activities should be estimated while planning a tuberculosis prevalence survey. It will help in proper utilization of resources and adjusting sample si/e and thus reducing total cost under an investigative procedure.
