AbstractIt is widely recommended that beta-blockade be used peri-operatively as it may reduce the incidence of postoperative cardiovascular complications including death. However, there are few data concerning the cost-effectiveness of such strategies. We have analysed the pharmacoeconomics of acute beta-blockade using data from eight prospective peri-operative studies in which patients underwent elective non-cardiac surgery, and in which the incidence of adverse side-effects of treatment, as well as clinical outcomes, have been reported. The costs of treatment were based on the NHS reference costs for 2004. From these data, the number-needed-to-treat (NNT) to prevent a major cardiovascular complication (including cardiovascular death) in high-risk patients was 18.5. This is comparable to the NNT for peri-operative statin therapy. The incremental cost of peri-operative beta-blockade (costs of drug acquisition and of treating associated adverse drug events) was 67.80 pounds sterling per patient. This results in a total cost of 1254.30 pounds sterling per peri-operative cardiovascular complication prevented. However, there is evidence that in patients at lower cardiovascular risk, beta-blockers may be potentially harmful, since their adverse effects (hypotension, bradycardia) may outweigh their potential cardioprotective effects.
