To the Editor We thank Shinall et al1 for their study analyzing the association of preoperative frailty and postoperative mortality (POM) at varying levels of operative stress as measured by the Operative Stress Score. In addition to lending further credibility to the aforementioned association across varying surgical procedures, they were able to highlight this in the context of low-stress and very low-stress procedures. With an increasing average life expectancy, surgical interventions in individuals with inadequate physiological reserves and reduced stress response will only grow. However, we would like to address a few points that could strengthen the association.
