OBJECTIVE To determine the cost-effectiveness of treatment with caffeine compared with placebo for apnea of prematurity in infants with birth weights less than 1250 g, from birth through 18 to 21 months' corrected age. METHODS We undertook a retrospective economic evaluation of the cost per survivor without neurodevelopmental impairment by using individual-patient data from the Caffeine for Apnea of Prematurity clinical trial (N = 1869). We included direct medical costs either to the insurance payer or the hospital but excluded costs to parents and society, such as lost productivity. We used a price of $0.21/mg of generic caffeine citrate for our base-case analysis. All costs were expressed in 2008 Canadian dollars and discounted at 3%. The time horizon for this analysis extended through 18 to 21 months' corrected age to match the clinical trial. RESULTS The mean cost per infant was $124 466 in the caffeine group and $133 505 in the placebo group (difference: $9039 [-14 749 to -3375]; adjusted P = .014). Cost-effectiveness analysis showed caffeine to be a dominant or "win-win" therapy: in >99% of 1000 bootstrap replications of the analysis, caffeine-treated infants had simultaneously better outcomes and lower mean costs. These results were robust to a 1000% increase in the individual resource items, including the price of caffeine citrate. CONCLUSIONS In comparison with placebo, caffeine therapy for apnea of prematurity in infants weighing less than 1250 g is economically appealing for infants up to 18 to 21 months' corrected age.

D002110 Caffeine A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling. 1,3,7-Trimethylxanthine,Caffedrine,Coffeinum N,Coffeinum Purrum,Dexitac,Durvitan,No Doz,Percoffedrinol N,Percutaféine,Quick-Pep,Vivarin,Quick Pep,QuickPep
D003362 Cost-Benefit Analysis A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. In contrast a cost effectiveness in general compares cost with qualitative outcomes.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
