Failure to rescue in surgical patients: A review for acute care surgeons.

The Failure to Rescue (FTR) rate is defined as the mortality rate among patients who experience one or more complications. It has been used as an outcome metric for approximately 25 years, primarily in elective surgery populations, and has been shown to be associated with factors that are modifiable on the institutional level. Although the FTR metric was derived in elective surgical populations, modifications have been made in attempts to refine the metric and apply it to broader populations, including medical patients and non-elective surgical patients. However, study among emergency general surgery patients has been limited. In this review, we summarize the current knowledge surrounding FTR, including established risk factors and potential limitations of the metric in emergency general surgery (EGS) populations. We then discuss a conceptual model for FTR events and review strategies to minimize rates. Finally, we provide a brief overview of current areas of study and potential future directions in acute care surgery.
