Pharmacoeconomics in anaesthesia: what are the issues?

Abstract

Newer anaesthetic agents provide a faster onset, easier titration and a more rapid recovery than the older agents, but are more expensive. In assessing the financial consequences associated with their use, it is important to examine the total costs (including personnel costs) and not just the acquisition costs of new drugs. Claims of cost savings from new drugs should be subjected to close scrutiny, with studies designed to demonstrate that the preferential use of the newer drug is associated with actual decreased payments for personnel, an earlier return to normal activities by the patient and/or their caretakers, or the completion of an additional case in the same operating session. It may be necessary to alter work patterns to obtain the full benefits of the new drugs (e.g. bypass of the labour-intensive [phase I] postanaesthetic care unit). Finally, greater cost savings in the operating room can be achieved by increasing efficiency in resource utilization. A delay in starting a case, or a prolonged turnover time between cases, can negate any cost savings related to the anaesthetist's choice of drugs.
