Abstract:OBJECTIVE: To explore new approaches to increase the detection of tuberculosis cases (TB).
DESIGN: Thirty counties participated in the study. Patients with TB symptoms were surveyed and referred by trained village doctors to county dispensaries, designated township health centres or general hospitals for free sputum examination. TB patients and suspects notified by general hospitals were traced by TB staff if they defaulted during the transfer.
RESULTS: A total of 12091 new smear-positive TB cases were detected. The registration rate of new smear-positives increased from 36.2 per 100000 population before the project to 49.9/100000 after the project, and the case detection rate under the DOTS strategy reached 86%. Of 43464 registered TB suspects, 15363 (35.3%) were referred by village and hospital doctors. The referral rate increased significantly (P < 0.01). Of the 15363 referred patients, 3870 were diagnosed as new smear-positive TB cases. Among three different microscopy centres, there was a statistically significant difference in the sputum examination rates of TB suspects and in the smear-positive rates among the suspects examined. The follow-up rate was 70.9%, but the follow-up success rate was only 33.1%.
CONCLUSIONS: Intensive referral of patients with TB symptoms by village doctors to TB dispensaries is an effective way of increasing detection. At the same time, incentives are necessary for patients and village doctors.
