SummaryPrevious studies recommend a watch-and-wait approach to paraesophageal hernia (PEH) repair due to an increased risk for mortality. While contemporary studies suggest that elective surgery is safe and effective, many patients presenting with PEH are elderly. Therefore, we assessed the impact of frailty on in-hospital outcomes and healthcare utilization among patients receiving PEH repair. This retrospective population-based cohort study assessed patients from the National Inpatient Sample database who received PEH repair between October 2015 to December 2019. Demographic and perioperative data were gathered, and frailty was measured using the 11-item modified frailty index. The outcomes measured were in-hospital mortality, complications, discharge disposition, and healthcare utilization. Overall, 10,716 patients receiving PEH repair were identified, including 1442 frail patients. Frail patients were less often female and were more often in the lowest income quartile compared to robust patients. Frail patients were at greater odds for in-hospital mortality [odds ratio (OR) 2.83 (95% CI 1.65–4.83); P < 0.001], postoperative ICU admissions [OR 2.07 (95% CI 1.55–2.78); P < 0.001], any complications [OR 2.18 (95% CI 1.55–2.78); P < 0.001], hospital length of stay [mean difference (MD) 1.75 days (95% CI 1.30–2.210; P < 0.001], and total admission costs [MD $5631.65 (95% CI $3300.06–$7.963.24); P < 0.001] relative to their robust patients. While PEH repair in elderly patients is safe and effective, frail patients have an increased rate of in-hospital mortality, postoperative ICU admissions, complications, and total admission costs. Clinicians should consider patient frailty when identifying the most appropriate surgical candidates for PEH repair.
