"Failure to rescue" patients with complications is a factor contributing to high mortality rates after elective surgery. In trauma, where early deaths are the primary contributors to a trauma center's mortality rate, the rescue of patients with complications might not be related to overall trauma center mortality. We assessed the extent to which trauma center mortality was reflected by the center's ability to rescue patients with major complications.
Data were derived from the National Trauma Databank, and limited to adults with an Injury Severity Score ≥9 and to centers with adequate complication reporting. Regression models were used to produce center-level adjusted rates for mortality and complications. Centers were ranked on their adjusted mortality rate and divided into quintiles.
Of 76,048 patients, 9.6% had a major complication and 7.9% died. The mean complication rate in the quintile of centers with the highest mortality rates was 11.1%, compared with 7.7% in the quintile of centers with the lowest mortality rates (p=0.03). In addition, mortality among patients with complications differed significantly across quintiles. The mean mortality among patients with complications was 20.3% in the quintile of centers with the highest overall mortality rates, compared with 11.1% in the quintile of centers with the lowest overall mortality rates (p<0.001).
Unlike reports from elective surgery, complication rates after severe injury differ across centers and parallel mortality rates. Centers with low overall mortality are more successful at rescuing patients who experience complications. A lower risk of complications and better care of those with complications are both at play in high-performing trauma centers.
对有并发症的患者“抢救失败”是导致择期手术后高死亡率的一个因素。在创伤领域,早期死亡是创伤中心死亡率的主要原因,对有并发症患者的抢救可能与创伤中心的总体死亡率无关。我们评估了创伤中心的死亡率在多大程度上反映了该中心抢救有严重并发症患者的能力。
数据来源于国家创伤数据库,仅限于损伤严重程度评分≥9分的成年人以及有充分并发症报告的中心。使用回归模型得出中心层面调整后的死亡率和并发症发生率。根据调整后的死亡率对各中心进行排名,并分为五等份。
在76048例患者中,9.6%发生了严重并发症,7.9%死亡。死亡率最高的五分之一中心的平均并发症发生率为11.1%,而死亡率最低的五分之一中心为7.7%(p = 0.03)。此外,各五等份中并发症患者的死亡率有显著差异。总体死亡率最高的五分之一中心中,有并发症患者的平均死亡率为20.3%,而总体死亡率最低的五分之一中心为11.1%(p < 0.001)。
与择期手术的报告不同,严重损伤后的并发症发生率因中心而异且与死亡率平行。总体死亡率低的中心在抢救有并发症的患者方面更成功。在表现出色的创伤中心,并发症风险较低以及对有并发症患者的治疗更好这两个因素都在起作用。
