There is an incremental increase in hospital resources consumed by surviving Medicare Beneficiaries (MBs) experiencing a major complication during admission for CABG.
This retrospective study uses the 2010 MEDPAR File to identify 102,427 MBs who survived isolated CABG (without valve surgery). Hospital costs were estimated from charges using the hospital's overall cost–to–charge ratio. Complications were identified by ICD–9–CM codes. Complications are included in the accompanying table. Increased incremental cost and incremental LOS were calculated by subtracting the average observed value for all MBs without any study complications from the average observed value among those MBs experiencing the selected complication.
Overall, 31,969 (31.2%) MBs in the study experienced at least one study complication. The average hospital cost of MBs who experienced at least one of the major complications was $42,612 (mean stay 11.9 days) compared to $32,634 (mean stay 8.8 days) among MBs without complications. The table reports incremental cost and LOS for each complication.
This study indicates that complications associated with CABG significantly increase hospital costs and LOS. The size for the incremental cost for these complications suggests that efforts to minimize them should be cost effective.
