Implementation of a Free Water Protocol at a Long Term Acute Care Hospital: A Feasibility Study

Abstract

This feasibility study aimed to trial a Free Water Protocol (FWP) for patients with thin liquid dysphagia in the Long-Term Acute Care Hospital (LTACH) setting. Patients with dysphagia are often prescribed thickened liquids to avoid or mitigate aspiration. While this clinical intervention can minimize the risk of aspiration pneumonia (PNA), it is generally not well received by patients. As such, the goal of this study was to determine if patients who knowingly aspirate thin liquids can safely tolerate thin liquid water, and if so, to what degree of benefit. The study assessed for adverse events, fluid intake, hydration status, quality of life, and overall swallow function outcomes. These measurements were taken over a 7 day trial period using inventories, lab work, clinical judgment, and observation for data collection. Ten patients were enrolled in this study with 9 participants having sufficient data for analysis (n=9). No adverse events related to the FWP were observed, and patients saw improved total fluid intake (p=0.0073), swallow-related quality of life (p=0.0273), and overall swallow function (p=0.0001). The results in this feasibility study allowed for the hospital wide implementation of the FWP and laid out the groundwork for future studies looking at longitudinal effects of a FWP.
