Table 3.

Program performance. The incremental cost-effectiveness of evaluation and treatment of disease among a hypothetical cohort of 1 000 B-notification patients followed for 20 years. This table presents the outcomes for the active case finding component of the program, and lists the number of QALYs averted, the net cost, the number of cases averted, and the difference in the number of deaths among individuals with tuberculosis with and without active case finding, for three levels of the evaluation rate. All outcomes are discounted at a rate of three percent per year. Each row is computed by averaging 10 000 replications of a cohort of 1 000 individuals each, over a 20-year period; standard errors are given in parentheses.

Evaluation Rate	Starting Rate	Completion Rate	QALYs Saved	Net costs (1000s)	Cases Averted	TB Deaths Averted
45%	-	-	1.9 (0.09)	-11 (0.5)	0.18 (0.02)	0.059 (0.003)
65%	-	-	2.9 (0.08)	-16 (0.5)	0.26 (0.02)	0.089 (0.004)
