INTRODUCTION: Frailty is a measure of physiologic reserve that is frequently cited as a predictor of postoperative complications. However, the effect of frailty on patients undergoing a relatively common procedure such as transsphenoidal resection of pituitary tumors (TSRPT) is unknown. Therefore, we sought to explore this relationship using a large, national database.
METHODS: The 2006-2014 American College of Surgeons National Surgical Quality Improvement Program database was retrospectively reviewed to identify all patients who underwent TSRPT. Frailty scores were assigned using the established 11-factor modified Frailty Index (mFI-11). Patients were divided into low-frailty and high-frailty groups, based on mFI comorbidities of ≤ 1 and ≥ 2, respectively. Univariable and multivariable analyses were performed to evaluate the impact of frailty on postoperative outcomes and mortality.
RESULTS: A total of 993 patients were included in the analysis. The low-frailty group consisted of 825 patients; the high-frailty group comprised 168 patients. In univariable analysis, there were no significant differences in medical (low-frailty 4.8%, high-frailty 8.3%; p = 0.069) and surgical (low-frailty 1.1%, high-frailty 1.2%; p = 1.000) complications; however, the high-frailty group had a higher rate of mortality (3%) when compared with the low-frailty group (0.6%; p = 0.016, OR 4.07, p = 0.044) and longer hospitalization (4.5 ± 7.4 vs. 5.8 ± 6.8 days; p = 0.023). In multivariable analysis, frailty was a predictor of mortality but not complications or reoperation.
CONCLUSIONS: Our study shows that frailty, as measured by the mFI-11, does not predict postoperative complications in patients who undergo TSRPT, but greater frailty is correlated with higher mortality and increased hospital length of stay.
