Significant differences were observed in Wellness Marker (p=0.004) and phase angle (p=0.006) amongst patients in the 3 SGA categories, and these BIA parameters were associated with perioperative pneumonia (p=0.011 and p=0.032 respectively).

Why the study?

Patients with head and neck malignancies are vulnerable to malnutrition, which impacts morbidity and mortality, prompting evaluation of bioimpedance analysis to assess nutritional status and perioperative complication risk.

Does bioelectrical impedance analysis predict nutritional status and perioperative complications in patients undergoing surgery for head and neck malignancies?

Population

61 patients admitted for elective head and neck surgery

Comparison

BIA parameters correlated with SGA scores and perioperative complications

Design

Cohort study

Overview

May support BIA alongside SGA for preoperative risk stratification; hypothesis-generating for pneumonia prevention in head and neck cancer surgery.

Structured PICO

Does bioelectrical impedance analysis predict nutritional status and perioperative complications in patients undergoing surgery for head and neck malignancies?

P
Population
61 patients admitted for elective head and neck surgery for malignancies, mean age 62 ± 1.6 years, 45 males and 16 females.
I
Intervention
Bioelectrical impedance analysis (BIA) using Bodystat Quadscan 4000 performed prior to surgery.
O
Outcome
Correlation of BIA parameters (phase angle and Wellness marker) with Subjective Global Assessment (SGA) scores, and association with perioperative complications (pneumonia, surgical site infections, salivary leak/fistula, flap complications).

Bioelectrical impedance analysis parameters correlate with Subjective Global Assessment scores and can help identify patients at risk for perioperative pneumonia in head and neck cancer surgery.
