Correspondence on "Higher hospital frailty risk score is associated with increased complications and healthcare resource utilization after endovascular treatment of ruptured intracranial aneurysms" by Koo et al

We read with great interest the recently published article by Koo et al.1 This retrospective cohort study used the Hospital Frailty Risk Score (HFRS) to measure ‘frailty’ and its association with complication rates and healthcare resource utilization in patients who underwent endovascular treatment of ruptured intracranial aneurysms. Koo et al used ICD-10-CM codes to identify patients, who were then categorized into frailty groups: low (HFRS <5), intermediate (HFRS 5–15), and high (HFRS >15). The study concluded that greater frailty, as defined by the HFRS, was associated with increased postoperative complications, length of hospital stay, total healthcare cost, and non-routine discharge disposition. We would appreciate clarification from the authors regarding the following concerns. The HFRS is a risk score derived from >1000 ICD-10-CM codes over-represented in a population of hospitalized older adults (≥75 years of age).2 One of the most concerning aspects of the HFRS design...
