A study on awareness of symptoms of pulmonary TB and action taking was repeated in the 62 villages and 4 town blocks of Tumkur district of Karnataka after an interval of 12 years. In the earlier study, 2106 persons formed the study population. In the present study, 1752 were intaken to obtain a comparison of these 1752 intaken persons who were eligible for interview, 875 were X-ray positive and 877 X-ray normal (matched control).

The study showed that 95% of patients having radiologically active TB by both X-ray readers, 70% by one reader, 49.5% inactive by both readers, were aware of symptoms. According to the bacteriological status 79.5% had symptoms among those who were sputum positive by both microscopy and culture, 62.2% among those positive by culture alone and 73.7% among patients sputum positive by any method. Regarding action taking it was observed that 49.5% of the bacteriologically positive patients took some action compared by 70% of those found to have radiologically active disease by both X-ray readers. Thus, action taking was higher among the latter category in both the studies. It may be due to the fact that extent of lesions are less advanced among those bacteriologically positive than among those who were in radiologically positive stage.

The findings of the study are similar to the earlier awareness study carried out in 1963 in the same area (Tumkur). This also indicates that in spite of having advantage of DTP for a decade actual and total benefits have not reached the people.

NTP reaches people through PHCs and sub centres. A study was conducted to find out the perception of illness and utilisation of health facilities by the community. This study was conducted in a random sample of 48 villages selected according to Probability Proportioned to Size within 5 kms. of the selected PHIs in Kolar district using a multi stage sampling technique. Information on socio-economic status, availability of health services and their utilisation was collected. 13,323 individuals were interviewed. 706 were ill in a period of two months prior to survey. 71.3% had taken allopathic system of treatment. 69.1% had approached government hospital or PHC. 34 patients reported to have TB. All had attended either DTC or PHC.

The study indicated that morbidity was perceived much early and also followed by an action. Data indicates a high percentage of preferring allopathic system in general and from peripheral health centres and other government hospitals in particular. Data indicates that in spite of overall backwardness of the study area and very limited economic resources people have utilised the PHC to the maximum. The reason could be either high acceptance of PHC or inevitability. But, there is an evidence of higher utilisation of family welfare and MCH services. The data shows all TB patients have had exposure to standard regimens, all of them have approached either PHC or DTC for treatment. This confirms the felt need oriented concept of NTP. Also high level of morbidity among children below 4 years of age and action taken indicate an enhanced level of demand for health services.
