Abstract: Results A total of 5 985 TB patients aged（31.05±10.88）years (mean±SD) were included in the study.Of them, 63.86% (3 822/5 985) were males, 36.14% (2 163/5 985) were females, and 94.72% (5 669/5 985) were floating population.The median of outpatient medical expenses was RMB 2 596.10 Yuan, in which the mean expenses of examination, supportive drugs, other drugs, and other fees were 1 512.14 (56.81%), 627.50 (24.33%), 348.80 (17.02%), and 43.75(1.84%）Yuan, respectively.Nonlocal, retreatment, and smear-negative patients had higher medical expenses than local, initial treatment, and smear-positive patients, respectively (P<0.01 for all).Multiple linear regression showed that nonlocal patients had ligher medical expenses than local patients (β=0.017, P<0.01), retreatment patients had higher expenses than initial treatment ones (β=0 093,P<0.01), smear-positive patients at the end of two months had higher expenses than smear-negative ones (β=0.048,P<0.01), and patients with pulmonary cavity had higher expenses than those without pulmonary cavity (β=0.043,P<0.01).Conclusion Examination expenses largely accounted for the total outpatient medical expenses of TB patients in Baoan District, Shenzhen.The medical expenses varied in different types of TB patients.
