Objectives:
to compare possible outcomes of the non-operative treatment for intermittent claudication with that of surgery.
Design:
decision tree approach using published and vascular registry data. The valuation of clinical outcomes was estimated by index weights using the Rosser index and the Quality of Well-Being scale.
Setting:
routine health care in Sweden.
Materials:
published data on 224 non-operatively treated claudicants and data from 805 claudicants treated with surgery or angioplasty from the Swedvasc registry. No diabetics were included. Chief outcome measure: expected utility value at one year after decision on treatment given the clinical data and the estimated health status valuations.
Main Results:
it was possible to identify a success rate for surgery above which it was the better alternative. However, depending on which of two health indices that was used, and if reconstruction was supra- or infrainguinal, this threshold value varied from 0-81%.
Conclusions:
reliable measures of the value of outcomes have to be developed and, in addition, long-term data on outcome and costs in routine care have to be collected before a comprehensive economic assessment based on the decision tree approach can be made to support decisions on treatment for intermittent claudication.
