Is it time to rebalance the case mix? A portfolio analysis of direct catheterization laboratory costs over a 5-year period

摘要

BackgroundCardiac catheterization laboratories (CLL) have continued to function as profit centers for hospitals. Due to a high percentage of material and labor costs, they are natural targets for process improvement. Our study applied a contribution margin (CBM) concept to evaluate costs and cost dynamics over a 5-year period.
