Potential and performance of case of age, who contributed only 0.5% to the total chest symptomatics and no case of tuberculosis. Among the 32,810 out patients, as many as 944 (3.7%) were chest symptomatics, aged _ 10 years who were subjected to sputum examination by smear and culture. Among the 944 symptomatics, 86(94%) were found positive by smear and 87(9.5%) by culture. Both the number of chest symptomatics and the case yield increased with age. Highest number of cases came from the 35-44 years age group. Females constituted 45% of the out patients but contributed only 18.6% to the cases. The work load on account of tuberculosis was 1 to 2 sputum examinations per day per PHI, which could be managed with the existing staff posted in each PHI. For comparing potential with actual performance, a total of 11,881 out patients were registered by a PHI team in the same set of PHIs at an interval of 6-8 months, by rotation. Of them, 149(1.25%) were categorised as chest symptomatics, among whom there were only 12(8.5%) smear positive and 16(11.4%) culture positive cases. Thus, the estimated potential of case finding for the whole study district was 2,240 smear positive cases per year. This number could be compared with 305 cases as the actual performance. The case finding efficiency was, therefore, 14% in respect of smear positives in the context of the potential.
