Key result
Adding geriatric risk factors to the ACS NSQIP calculator predicts postoperative geriatric outcomes with >0.8 discrimination.
Why the study?
The authors sought to enhance the existing ACS NSQIP SRC with functionality to predict geriatric-specific outcomes and evaluate the predictive value of geriatric-specific risk factors.
Does the inclusion of geriatric risk factors in the ACS NSQIP Surgical Risk Calculator improve the prediction of postoperative geriatric outcomes in patients 65 years or older?
Population
38,048 patients 65 years or older undergoing 197 unique operations across 10 surgical subspecialties
Comparison
27-variable models with geriatric risk factors vs traditional 21-variable ACS NSQIP SRC models
Design
Multicenter risk-prediction model study

May aid preoperative risk assessment in older surgical patients; extends NSQIP calculator but leaves open need for prospective validation.
Observational (n=38,048)

Does the inclusion of geriatric risk factors in the ACS NSQIP Surgical Risk Calculator improve the prediction of postoperative geriatric outcomes in patients 65 years or older?
Effect estimate: C statistic >0.8
Adding geriatric-specific risk factors to the ACS NSQIP Surgical Risk Calculator improves the prediction of postoperative complications such as delirium and functional decline in older adults.
Hornor et al. (2019) conducted an observational in Geriatric surgical patients (n=38,048). 27-variable ACS NSQIP SRC models including 6 geriatric risk factors vs. Traditional 21-variable ACS NSQIP SRC models was evaluated on 4 postoperative geriatric outcomes (pressure ulcer, delirium, new mobility aid use, and functional decline) (C statistic >0.8). Adding 6 geriatric risk factors to the traditional 21-variable ACS NSQIP Surgical Risk Calculator demonstrated excellent performance (C statistic >0.8) in predicting 4 postoperative geriatric outcomes.
