Abstract
We conducted a thorough literature review on the emerging role of failure to rescue (FTR) as a quality metric for cardiovascular surgery and critical care. For this purpose, we identified all original research studies assessing the implementation of FTR in cardiovascular surgery and critical care from 1992 to 2023. All included studies were evaluated for their quality. Although all studies defined FTR as mortality after a surgical complication, a high heterogeneity has been reported among studies regarding the included complications. There are certain factors that affect the FTR, divided into hospital- and patient-related factors. The identification of these factors allowed us to build a stepwise roadmap to reduce the FTR rate. Recently, FTR has further evolved as a metric to assess morbidity instead of mortality, while being also evaluated in the context of interventional cardiology. All these advances are further discussed in the current review, thus providing all the necessary information to surgeons, anesthesiologists, and physicians willing to implement FTR as a metric of quality in their establishment.
