Background:
The geriatric nutritional risk index (GNRI) is a tool to assess preoperative nutritional status that can be calculated simply based on height, weight, and serum albumin. This study assesses the utility of GNRI in predicting postoperative complications in patients undergoing major head and neck cancer (HNC) surgery.
Methods:
Retrospective review of the 2016-2020 National Surgical Quality Improvement Program database. Patients were categorized into GNRI > 98 (normal nutritional status), GNRI 92-98 (moderate malnutrition status), and GNRI < 92 (severe malnutrition status). Univariable and multivariable binary logistic regression analyses were performed.
Results:
Sixteen thousand seven hundred eight-nine patients undergoing HNC resection were included. On multivariable analysis, moderate and severe malnourishment based on GNRI remained significantly associated with any surgical complication, any medical complication, any complication, Clavien-Dindo grade IV complications, and 30-day mortality.
Conclusions:
GNRI may have utility as a potentially modifiable preoperative prognostic factor that can be optimized to improve complications and mortality following HNC resection.
Level Of Evidence:
Level 4.
