We evaluated the hospital frailty risk score (HFRS) as a risk factor of 90-day mortality in VA ECMO patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective analysis of VA ECMO patients at Johns Hopkins Hospital from 2016 to 2024. HFRS was derived from ICD-10 codes. An optimal frailty cut point was determined using maximally selected rank statistics, and patients were subsequently stratified into high (&gt;10) and low (&lt;=10) frailty groups. Cox proportional hazards models evaluated the association between frailty and mortality, adjusting for demographics, comorbidities, and clinical variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>180 patients receiving VA ECMO were included (median age:53 years, 46.2% female). Overall, 25 patients (13.9%) were classified as high frailty (HFRS &gt;10) and 155 (86.1%) as low frailty (HFRS\u226410). Of the 180 patients, 80 patients survived 90-days following initial ECMO cannulation. Median HFRS was higher among non-survivors (4.9 vs 3.4), with a greater proportion classified as high frailty (18.0% vs 8.8%). In multivariable Cox regression adjusting for demographics, comorbidities, and clinical covariates, low HFRS remained independently associated with reduced 90-day mortality (HR=0.47, 95% CI 0.26\u20130.87, p=0.017), while obesity (HR=10.44) and older age (HR 1.02) were independently associated with increased mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>HFRS is independently associated with 90-day mortality in patients undergoing VA ECMO.
