High frailty risk was strongly associated with increased in-hospital mortality compared to low frailty risk (OR 24.58; 95% CI 21.55-28.04) across surgical specialties.

Does frailty increase the risk of in-hospital mortality and nonhome discharge in patients over 65 years old undergoing surgery?
Frailty is strongly associated with increased in-hospital mortality and nonhome discharge across surgical subspecialties in older adults.
Effect estimate: OR 24.58 (high risk) (95% CI 21.55-28.04)
ABSTRACT Background and Aims Frailty is associated with adverse surgical outcomes in older adults, but it remains unknown if this association is consistent across all surgical specialties. This study aimed to evaluate the relationship between frailty and postoperative outcomes across surgical specialties using the National Inpatient Sample (NIS) database. Methods The NIS database between 2016 and 2018 was queried to analyze surgical admissions for patients over 65 years old. Frailty was assessed using the Hospital Frailty Risk Score (HFRS), categorizing patients into low ( 15) risk groups. Our primary outcome was in‐hospital mortality, and our secondary outcome was nonhome discharge. Multivariable logistic regression was performed to determine the association between frailty and our outcomes. Results Among 1,826,285 surgical admissions that met the inclusion criteria, 65.0% were classified as low frailty risk, 32.0% as intermediate risk, and 3.0% as high risk. Higher frailty scores were associated with increased in‐hospital mortality (intermediate risk: OR 9.61, 95% CI: 8.96–10.30; high risk: OR 24.58, 95% CI: 21.55–28.04) and higher odds of nonhome discharge (intermediate risk: OR 2.99, 95% CI: 2.94–3.04; high risk: OR 14.82, 95% CI: 13.64–16.10). Frail patients underwent emergent procedures at significantly higher rates than nonfrail patients (91.3% vs. 26.3%). In sensitivity analyses, frail patients consistently demonstrated increased levels of in‐hospital mortality and nonhome discharge across all surgical subspecialties. Conclusions Frailty, as measured by the HFRS, is strongly associated with increased in‐hospital mortality and nonhome discharge across surgical subspecialties, especially in emergent settings. Our study demonstrates the need to account for frailty to inform patient‐centered care and enhance surgical decision making.
Gonzalez et al. (Sun,) conducted a cohort in Surgical admissions (n=1,826,285). Frailty (Hospital Frailty Risk Score) vs. Low frailty risk was evaluated on In-hospital mortality (OR 24.58 (high risk), 95% CI 21.55-28.04). High frailty risk was strongly associated with increased in-hospital mortality compared to low frailty risk (OR 24.58; 95% CI 21.55-28.04) across surgical specialties.
