<p id="P2">Surgical site infections (SSIs) are common following pancreatectomy and
associated
with significant morbidity and economic burden. We sought to identify distinct predictors
for the development of superficial versus deep/organ space SSIs and their effects
on surgical outcomes.

<h5 class="section-title" id="d8852269e201">Methods</h5>
<p id="P3">ACS-NSQIP targeted pancreatectomy 2014 and 2015 databases were queried.
Univariate
and multivariate models were developed for both types of SSI, length of stay (LOS),
and readmission. Costs were estimated based on the Centers for Medicare & Medicaid
Services (CMS) recommendations.

<h5 class="section-title" id="d8852269e206">Results</h5>
<p id="P4">Of 8 093 patients, there were 422 (5.2%) superficial and 1 005 (12.4%)
deep/organ
space SSIs. On multivariate analyses, preoperative biliary stenting was a predictor
only for superficial SSI (OR: 2.21), while BMI of 25–29.9 (OR: 1.25) and BMI ≥30kg/m
<sup>2</sup> (OR: 1.53), pancreatic duct size <3mm (OR: 1.30), and intermediate
(OR: 1.67) versus
hard gland texture were predictors of deep/organ-space SSI. Superficial and deep/organ
space SSIs were independent predictors of prolonged LOS (OR 1.74 vs 1.80) and readmission
(OR 2.59 vs 6.57). Additional readmission costs per patient secondary to superficial
SSI and deep/organ space SSI were $7 661.37 and $18 409.42, respectively.

<h5 class="section-title" id="d8852269e214">Conclusion</h5>
<p id="P5">Deep/organ space SSI contributes more profoundly to prolonged hospital
stay, readmission,
and additional costs, suggesting that strategies should focus on preferential prevention
of deep/organ space infections.
