| The increasing prevalence of emergency operations in the growing geriatric population necessitates a focus on quality
indicators to improve surgical outcomes. This study investigates the impact of emergency operative volume on mortality in
geriatric general surgery (EGS) patients aged 65 and older. Utilizing beta-logistic generalized linear regression, hospital
mortality was quantified, and operative volume thresholds were determined to optimize survival probability. The analysis
encompassed 299 hospitals and 41,860 operations, revealing that an increase in hospital emergency operations volume
significantly reduces mortality. Specifically, mortality decreased from 14% to 61% with each operation, as the logarithm of
volume doubled. A median of 14 operations was identified as the threshold for achieving a 95% estimated survival
probability. However, two-thirds of hospitals did not meet these benchmarks for more than half of their patients. The
findings highlight that higher operative volumes correlate with better survival rates, supporting the Surgeons' Quality
Programs, which advocate using operative volume as a quality metric for emergency surgeries in geriatric patientsddd |
