Assessment for Enteral Feeding Intolerance by Critical Care Nurses: A National Survey.

Background: Enteral feeding intolerance (EFI) occurs in more than one-third of mechanically ventilated patients, yet the cause of this gastrointestinal dysfunction remains unclear. Assessment and diagnostic criteria are often vague and subjective leading to inaccurate recognition or diagnosis of EFI. Nurses are often unsure or unaware of appropriate assessment methods.

Use of Machine Learning Models to Predict Microaspiration Measured by Tracheal Pepsin A.

Background: Enteral feeding intolerance, a common type of gastrointestinal dysfunction leading to underfeeding, is associated with increased mortality. Tracheal pepsin A, an indicator of microaspiration, was found in 39% of patients within 24 hours of enteral feeding. Tracheal pepsin A is a potential biomarker of enteral feeding intolerance.
