Costs: endovascular aneurysm repair compared with open repair over 15 years

MethodsAll resources in the current analysis were costed at 2014/15 prices. The follow-up is divided into two periods:(1) 1 September 1999–31 August 2009; and (2) 1 September 2009–31 March 2015. The method of costing is different for the two periods. During the first period (1999–2009), detailed hospital resource use data were available for the index procedure and aneurysm-related reinterventions for each patient from the case record forms. The same methodology is used here as in the previous publication, 94 the only difference being that, in the previous publication, these resources were costed at 2008/9 prices. In the current analysis, these same resources have been recosted using largely new unit costs at 2014/15 prices (Table 13).
