A comparison of different theoretical diagnostic scenarios.

Notes: 1.Sensitivity = 0.55, 2 days delay in producing SSM test results. 2.Sensitivity = 0.59 (same as for 3 smears), zero delay in delivering sputum, producing results and in patient collecting results. 3.Sensitivity = 0.55, 2 days delay in producing SSM test results, P(treating ss-based on CXR) = 0.5 (up from 0.1). 4.Sensitivity = 0.55, 2 days delay in producing SSM test results, P(make 1st visit to clinic on given day) = 0.1 (up from 0.05). 5.Sensitivity = 0.59 (same as for 3 smears), zero delay in delivering sputum. 6.Sensitivity = 0.59 (same as for 3 smears due to reduced work load), 2 days delay in producing SSM test results. 7.Sensitivity = 0.59, 3 days delay in producing SSM test results. 8.Sensitivity = 0.36, rates of abnormal CXR kept the same, culture time for ss-patients = 8 weeks (up from 6), sensitivity ss-SSM kept the same. 9.LJ culture used in place of initial SSM test, culture time = 42 days, sensitivity = 1.0
