The study was carried out at Lady Willingdon Tuberculosis Demonstration & Training Centre, Bangalore to inquire into the epidemiological and sociological characteristics of patients attending a city TB clinic for the first time, to ascertain the reason for attendance and the nature of previous treatment if any. It was also to see whether there was a preference for seeking specialists and specialised services for alleviation of the symptoms experienced and whether there were any differences amongst the urban and rural attenders. A fifty per cent random sample of 2,658 out patients during 6l working days, formed the study population. They were interviewed by using a questionnaire based on the above mentioned objectives. 247 were not eligible due to incomplete record and below 5 years of age.

Majority of the out patients were in 20 30 years of age and were wage earners. Nearly 80% were aware of their symptoms and contained 95% of the tuberculosis cases detected at the clinic. Most of them were having 2 3 symptoms. No difference in time of reporting was observed among urban or rural patients; 61% of the urban and 42% of the rural patients attended the clinic within 3 months from the onset of their symptoms. Distance is a major obstacle. Upto 4.8 km the number of new outpatients was large but the case yield was poor. As the distance increased the out patients decreased but the case yield was more, suggesting a selective process influenced by distance. It was also found that 20% of the out patients came of their own without any prior contact with any other source of treatment, 32% had previous contact with other health institutions, 31% were actually referred by them and 17% were advised by BCG workers. Further analysis that of the 1,642 patients who had previous contact with health institutions, 84% were at general health institutions, 10% at specialised TB clinics and 6% were others. Of the remaining eligible 2,403 patients, 83% were from urban and 17% from rural areas. Sputum was collected from 2,308 patients. Of them, 179 (7.8%) were found to be positive by direct microscopy or culture or both and 169 were positive by culture (91% confirmation by culture). 131 (80%) were sensitive to isoniazid and 32 were isoniazid resistant.

The data obtained suggests that attendance at a specialized tuberculosis centre is not necessarily a function of awareness of symptoms and of the knowledge that such specialised services exist. It also does not support the theory that people prefer specialized institutions in cities. It is also seen than urban and rural patients behave in almost the same way in that their first contact for symptoms suggestive of tuberculosis, is initially at the general medical services and they should be strengthened with adequate means for diagnosis and treatment of tuberculosis.

Health has been defined as the state of perfect physical, social and mental wellbeing which is somewhat an abstract definition. In this paper economics of health is measured through economics of sickness. Because sickness is experienced, it can be measured and it inflicts physical social and economic sufferings. In a community, economic prosperity is directly dependent on quantum of sickness and its prevention by health services. A sociological enquiry into part played by disease in the socio economic development of society was made by carrying out a study in two village population groups. The social investigators of NTI made deep probing questions to elicit presence of symptoms, action taken by them, money spent on treatment and the loss of wages. In first study observation participation technique was also adopted. The investigators lived in the village for four months. In the other study 20% households of those 22 villages which participated earlier in an epidemiological survey conducted by NTI, were interviewed.

Findings of two studies are combined and presented. Illnesses were classified into major and minor on the basis of clinical severity and the duration of symptoms. In both the studies 60% of all persons were asymptomatic during 2 months prior to the interview. About 18% had one minor illness, 13% had major illness and only 3% had one major and one minor illness. The quantum of multiple disease (3 or more) occurring in one person was less than 2%. Only 20% of living man days were spent as sick man days. The average annual loss on account of health reasons per family has been estimated to be Rs.90 and Rs.15/ per capita. The overall economic loss due to sickness, direct and indirect amounted to 3% of the per capita income in the poorer groups of villages and 6% in the economically more favourable placed villages. The material available here strongly suggests that the sizes of households will not have much influence over the sickness in the community. Another significant feature of this study was the phenomenon- of substitution within the family whenever the wage earner could not go to work. The evidence examined in this paper suggests that the actual economic loss is only 1/3 of the calculated loss. It also suggests that the overall cost of sickness to the individuals and family is far less than what is normally calculated and is influenced by the money available in the household.
