Rupert Samuel4 (Received on 2.1.2001; Revised version received on 3.10.2001; Accepted on 30.10.2001) Summary Setting: Urban and rural areas of Karnataka state in south India where the Revised Tuberculosis National Control Programme based on Directly Observed Treatment, Short-course was not yet implemented. Objectives: To ascertain the time taken in seeking care among persons found to have cough of three weeks or more in the preceding 6 months and get details about the health care providers consulted, investigations undertaken, and costs incurred. Design: Interview with representative samples of 10,000 urban and 10,000 rural people from two districts in Karnataka, one representing more extensive public health care provider availability and the other representing less extensive facilities. Results: Reported prevalence of cough of any duration in the preceding 6 months was nearly 6%. And 1.4% had cough for 3 weeks or more {chest symptomatic persons [CS]); 6% of households had at least one CS. Cough increased with age. and was more common in males and in the lower socio-economic groups. The vast majority (83-90%) of CS had sought care, two thirds within 2 weeks and 81% within one month of symptom onset. In the district with a more extensive public health care provider system, CS sought care more promptly, the median interval between onset and reporting for care being 8.8 days compared with 12.8 days in the district with less extensive care provider system (P=O.O1). Private medical practitioners were the first provider sought by 65% of CS. Sputum examination was undertaken for only 35% of CS over an average of 8 encounters. Conclusion; Chest symptoms are relatively common in the community. Most CS seek care promptly, even where the public health care provider system is less extensive; most patients first seek care from private doctors. Only one third of patients had only a single sputum sample examined despite multiple encounters with the health system. Improvement in diagnostic and treatment services in the health system, rather than genera! health education, is the top priority. Key Words.-Chest symptoms, Chest Symptomatics, Behaviour patterns in seeking health care, Public and private health systems. INTRODUCTION Commencement of treatment in active cases.

DISCUSSION The vast majority of CS (81% in The NTP, initiated in 1962, emphasizes Mysore, 93% in Raichur) approached general diagnosing and treating tuberculosis in patients who health facilities for symptom relief and most of spontaneously attend health institutions. More than them (64% in Mysore, 77% in Raichur) half of the bacterioiogically positive cases identified restricted themselves to attending only one by a 1961 community epidemiological survey were facility. Private doctors (PMPs) were the most found to have attended a health facility on their own common first choice (average 65%, range 44- for relief of symptoms. 1 1 This finding was 93%), the reasons being proximity to home, 12 reconfirmed in 1973 in the same area.
