Abstract:
|
Statistical methods are given for producing a cost-effectiveness frontier for an arbitrary number of programs. In the deterministic case, the net health benefit (NHB) decision rule is optimal; the rule funds the program with the largest positive NHB at each lambda--the amount a decision-maker is willing to pay for an additional unit of effectiveness. For bivariate, normally distributed cost and effectiveness variables and a specified lambda, a statistical procedure is presented, based on the method of constrained multiple comparisons with the best (CMCB) for determining the program with the largest NHB. A one-tailed t test is used to determine if the NHB is positive. To obtain a statistical frontier in the lambda-NHB plane, we develop a method to produce the region in which each program has the largest NHB, by pivoting a CMCB confidence interval. At each lambda, the pointwise error rate is bounded by a prespecified alpha. Upper bounds on the familywise error rate--the probability of an error at any value of lambda--are given.
