Objectives/background: The Geriatric Surgery Verification (GSV) Program promotes clinical standards aimed to optimize the quality of surgical care delivered to older adults. The purpose of this study was to determine if preliminary implementation of the GSV Program standards improves surgical outcomes.
Design: Prospective study with cohort matching.
Setting: Data from a single institution compared with a national data set cohort.
Participants: All patients aged ≥75 years undergoing inpatient operations between January 2018 and December 2019 were included. Cohort matching by age and procedure code was performed using a national data set.
Measurements: Baseline pre- and intraoperative characteristics prospectively recorded using Veterans Affairs Surgical Quality Improvement Program (VASQIP) variable definitions. Postoperative outcomes were recorded including complications as defined by VASQIP, 30-day mortality, and length of stay.
Results: A total of 162 patients participated in the GSV program, and 308 patients comprised the matched comparison group. There was no difference in postoperative occurrence of one or more complications (p = 0.81) or 30-day mortality (p = 0.61). Patients cared for by the GSV Program had a reduced postoperative length of stay (median 4 days [range 1,31] vs. 5 days [range 1,86]; p < 0.01; and mean 5.4 ± 4.8 vs. 8.8 ± 11.8 days; p < 0.01) compared with the matched cohort. In a multivariable regression model, the GSV Program's reduced length of stay was independent of other associated covariates including age, operative time, and comorbidities (p < 0.01).
Conclusion: Preliminary implementation of the GSV Program standards reduces length of stay in older adults undergoing inpatient operations. This finding demonstrates both the clinical and financial value of the GSV Program.
