abstract="Objectives:  To carry out a pilot study to demonstrate the feasibility of the contingent valuation (CV) approach to identify net benefits gained from spinal interventions; and to conduct a formal cost-benefit analysis (CBA) using a retrospective study design. The study design is a CBA feasibility study using a CV survey with ex post willingness-to-pay/willingness-to-accept (WTP/WTA) questions. The CBA study was carried out in the specialty of spinal surgery.<p />",
