Frailty, hospital volume, and failure to rescue after head and neck cancer surgery

We previously reported that high‐volume hospital head and neck cancer (HNCA) surgical care is associated with decreased mortality, largely explained by reduced rates of failure to rescue. Frailty is an independent predictor of mortality, but is significantly less likely in patients receiving high‐volume care. We investigate whether differences in frailty rates explain the relationship between volume and outcomes in HNCA patients and whether frailty confounds the relationship between failure to rescue and mortality.
