We explore what effect controlling for various patient characteristics beyond a case-mix index (DRG) has on inferences drawn about the relative cost performance of hospital departments. We estimate fixed effect cost models in which 3754 patients are clustered within six Danish vascular...

Objective: The purpose is to assess whether the joint evaluation of costs and quality affects the ranking of hospital departments relative to performance based on cost performance alone.<p> Methods: Using patient level data, in which 3,754 patients across six vascular departments are pooled we...</p>
