Background: The impact of surgery compared to non-surgical management of older general surgical patients is not well researched. Methods: We examined the association between management and adverse outcomes in a cohort of emergency general surgery patients aged > 65 years. This multi-center study included 727 patients (mean+/-SD, 77.1 ± 8.2 years, 54% female) admitted to five UK hospitals. Data were analyzed using multi-level crude and multivariable logistic regression. Outcomes were: mortality at Day 30 and 90, length of stay, and readmission within 30 days of discharge. Covariates assessed were management approach, age, sex, frailty, polypharmacy, anemia, and hypoalbuminemia. Results: Approximately 25% of participants (n = 185) underwent emergency surgery. Frailty and albumin were associated with mortality at 30 (frailty OR = 3.52 [95% CI 1.66-7.49], albumin OR = 3.78 ([95% CI 1.53-9.31]), and 90 days post discharge (frailty OR = 3.20 [95% CI 1.86-5.51], albumin OR=3.25 [95% CI 1.70-6.19]) and readmission (frailty OR = 1.56 [95% CI (1.04-2.35)]). Surgically managed patients and frailty had increased odds of prolonged hospitalization (surgery OR = 5.69 [95% CI 3.67-8.80], frailty OR = 2.17 [95% CI 1.46-3.23]). Conclusion: We found the impact of surgery on length of hospitalization in older surgical patients is substantial. Whether early comprehensive geriatric assessment and post-op rehabilitation would improve this outcome require further evaluation.
