of registered cases among total pulmonary tuberculosis, bacteriological positive and smear positive cases in town and countryside had been increased in these five years. Contrary, the corresponding proportions in city were decreased. Special attention should be paid to above situation. The case-finding, transferring, notification and registration works in tuberculosis control programme in city areas should be further strengthened in the future.
2. Proportion of Registered Cases Among Known Cases
The proportions of registered case among known bacteriological positive and smear positive cases were 24.1% and 24.5% respectively. Although these proportions were higher than that in 1984/85 (11.6% and 11.9% respectively) and indicated that the proportion of registered cases was increased, but about 3/4 of detected infectious sources had not been registered and managed by tuberculosis control units and the situation was still so serious. So far as locality as concerned, theses proportions in city showed no significant change in these years; but these were considerably increased in town and countryside. Therefore, the increase of the proportion in the whole country as mentioned in above paragraphs were mainly attributed to the improvement of tuberculosis registration in town and countryside areas.
? MODE OF CASE-MANAGEMENT ON CHEMOTHERAPY AND PROPORTION OF INITIALLY TREATED AND RE-TREATED PATIENTS
1. Mode of Case-management on Chemotherapy
The case-management on chemotherapy for pulmonary tuberculosis patients particularly for infectious sources is important in improving the effectiveness of chemotherapy and eliminating infectious sources as well as in reducing the prevalence of tuberculosis.
In whole country: The situation of case-management on chemotherapy among 1,093 known bacteriological positive cases was as follows: 82.3% of the known bacteriological positive cases were not under case-management; only 17.7% were under case-management. Among those patients who were under case-management, the modes of case-management were as follows: 2.5%-full supervision mode, 5.8%-partial supervision mode, 9.4%- whole course management mode. Among 274 cases of initially treated bacteriological positive patients, 15.7% were under case-management. Among them, 1.8% were under full supervision, 4.8%-partial supervision, 9.1%- whole course management. Other 84.3% of initially treated bacteriological positive cases were not under case-management.
In provinces, municipalities and regions: Only those provinces, municipalities and regions who had more than five initially treated bacteriological positive patients were involved in following analysis. Jilin had the highest proportion (80% among 5 cases) of cases under case-management; Shandong (66.7% among 6 cases), Shaanxi (42.9% among 7 cases) and Jiangsu (41.2% among 7 cases) followed. Regarding the mode of case-management, Jilin also had the highest proportion of the mode of whole course management (80.0% among 5 cases); shandong (50% among 6 cases), Shaanxi(42.9% among 7 cases) came next. Xinjiang had the highest proportion (20% among 10 cases) of full supervision mode; Neimeng had the highest proportion (27.8% among 18 cases) of partial supervision mode. 119 initially treated bacteriological positive patients in 11 provinces and regions had received no case-management at all.
In city and countryside: In city, 50% among 10 known initially treated bacteriological positive cases were under case-management on chemotherapy; the corresponding proportions in town and countryside were 15.4% among 13 cases and 14.4% among 25 cases. In other words, 84.6% of known initially treated bacteriological positive cases in town and 85.6% in countryside were had no case-management on chemotherapy at all. In this connexion, the case-management on chemotherapy on infectious cases should be greatly strengthened particularly in countryside in future.
Supervised chemotherapy: Among 27 known bacteriological positive cases receiving fully supervised case-management, 92.6% was under medical personnel's supervision and 7.4% under specially trained family member's supervision. Among 63 known bacteriological positive cases receiving partly supervised case-management, 50.8% and 49.2% of the patients were under medical personnel's and trained family member's management respectively. Among 13 initially treated cases in this group, 38.5% and 61.5% were under medical personnel's and trained family member's case-management respectively.
2. Prevalence Among Initially Treated and Re-treated Patients
(1) Bacteriological Positive and Smear Positive Prevalence Among Initially Treated and Re-treated Patients
In whole country: The bacteriological positive prevalence and smear positive prevalence among initially treated patients were 13.7-264.8/100,000(mean 106.6/100,000) and 11.0-224/100,000(mean 76.4/100,000) respectively; among re-treated patients, they were 7.9-103/100,000(mean 56.9/100,000 and 5.5-86.6/100,000(mean 48.7/100,000) respectively.
In provinces, municipalities and regions: Hubei, Hunan, Xingjiang and Anhui had higher bacteriological positive prevalence and smear positive prevalence; the former were 103/100,000, 94.0/100,000, 91.6-100,000 and 84.9/100,000 respectively and the latter were 86.6/100,000,76.0/100,000, 75.5/100,000 and 78.8/100,000 respectively. Shanghai and Beijing had lower bacteriological positive prevalence and smear positive prevalence; the former were 7.9/100,000 and 8.2/100,000 respectively and the latter were 7.9/100,000 and 5.5/100,000 respectively.
