Serum potassium levels as an independent predictor of unplanned enteral nutrition discontinuation in older adults with gastroesophageal reflux disease.

Background & Aims: Enteral nutrition in older adults is often associated with intolerance, a phenomenon not well-understood in the context of gastroesophageal reflux disease (GERD). This observational study aimed to evaluate serum potassium levels as an independent prognostic factor for unplanned enteral nutrition discontinuation in older adults with GERD.

Methods: We conducted a retrospective analysis of 213 consecutive patients with GERD who received enteral nutrition at our institution from April 2018 to March 2023.
