EditorI would like to thank Drs Eberhart, Morin, Wulf, and Geldner1 for having taken an interest in patient preferences for immediate postoperative recovery states, and specifically for having validated my preliminary results.2 Although not published as a full report, the study has continued, with a near-doubling of subjects, but with very similar results.3 The qualitatively similar, but quantitatively different results reported by Eberhart and colleagues,1 may reflect their simplification of the simulation scenarios.
There does not appear to be much point in administering the simulation to patients just before anaesthesia, as Eberhart and colleagues did, especially as there was no plan to use the results to modify the anaesthetic management to suit their patients preferences. However, given that meeting patients preferences is a goal of high-quality care,4 it is tantalizing to wonder whether patients would actually regard care of higher quality if it were tailored specifically to address their preferences.
An additional comment is warranted regarding the notion of willingness-to-pay that I introduced into patient-preference studies,2 and which others1 5 6 have emulated. The naïve reader may conclude erroneously that the goal is to identify a price that the patient might actually be asked to pay, beyond whatever their insurance covers. Actually, the methodology is an approach to assessing societal benefit of a technology (e.g. prophylactic antiemetic therapy), acknowledging that financial resources are limited, whereas potential opportunities for spending are unlimited. Willingness-to-pay offers one of the few ways in the evaluation of health care interventions to perform a true cost benefit analysis, which is rarely possible because costbenefit analysis requires that all health outcomes be valued solely in monetary terms. One might hope that these studies will usher in greater interest in evaluating care from the patients perspective.
