Abstract

Background

Pancreatic cancer is a disease of older adults, who may present with limited physiologic reserve. The authors hypothesized that a frailty index can predict postoperative outcomes after pancreaticoduodenectomy (PD).

Methods

All patients who underwent PD were identified in the 2005–2012 NSQIP Participant Use File. Patients undergoing emergency procedures, those with an American Society of Anesthesiologists (ASA) classification of five, and those with a diagnosis of preoperative sepsis were excluded from the study. A modified frailty index (mFI) was defined by 11 variables within the National Surgical Quality Improvement Program (NSQIP) previously used for the Canadian Study of Health and Aging-Frailty Index. An mFI score of 0.27 or higher was defined as a high mFI. Uni- and multivariate analyses were performed to evaluate postoperative outcomes.

Results

This study enrolled 9986 patients (age 65 ± 12 years, 48.8% female) who underwent PD. Of these patients, 6.4% (n = 637) had a high mFI (>0.27). Increasing mFI was associated with higher prevalence of postoperative morbidity (p < 0.001) and 30-days mortality (p < 0.001). In the univariate analysis, high mFI was associated with increased morbidity (odds ratio [OR] 1.68; 95% confidence interval [CI] 1.43–1.97; p < 0.001) and 30-days mortality (OR 2.45; 95% CI 1.74–3.45; p < 0.001). After adjustment for age, sex, ASA classification, albumin level, and body mass index (BMI), high mFI remained an independent preoperative predictor of postoperative morbidity (OR 1.544; 95% CI 1.289–1.850; p < 0.0001) and 30-days mortality (OR 1.536; 95% CI 1.049–2.248; p = 0.027).

Conclusions

High mFI is associated with postoperative morbidity and mortality after PD and can aid in preoperative risk stratification.
