Implementation of a free water protocol at a long term acute care hospital

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. Ten participants were enrolled in this study with 9 having sufficient data for analysis (n = 9). No adverse events related to the FWP were observed, and patients saw improved total fluid intake (P = 0.0074), swallow-related quality of life (P = 0.0273), and overall swallow function (P = 0.0002). 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.

Perceived barriers and enablers for implementing water protocols in acute stroke care: A qualitative study using the Theoretical Domains Framework

Purpose: To identify perceived enablers and barriers that may influence the implementation of water protocols (WPs) as an intervention for dysphagia in acute stroke settings. Method: Semi-structured interviews were conducted with nine nurses, eight speech-language pathologists (SLPs), five doctors and four dietitians working in acute stroke units in a major city in Australia. Data were thematically analysed and themes were mapped to the Theoretical Domains Framework. Result: Ten barriers and nine enablers were identified. Key barriers were: nurses lack oral care skills and agency nurses lack stroke-specific skills; only SLPs are perceived to be involved with WPs; WP rules will not get followed and may lead to adverse patient outcomes; WPs increase nursing workload; transient workforce impacts efficiency of implementation; and established culture of using thickened fluids. Key enablers were: patients would benefit from WPs; communication and education systems are already in place; acute hospital brings unique benefits; and peer support and modelling support implementation. Conclusion: The perceptions of barriers and enablers to implementation of WPs can be used to inform future studies designed to evaluate the safety and efficacy of WPs and subsequently facilitate their uptake in acute stroke as an alternate dysphagia management strategy.

A systematic review and meta-analysis of pneumonia associated with thin liquid vs. thickened liquid intake in patients who aspirate

OBJECTIVE

To investigate whether drinking thin liquids with safety strategies increases the risk for pneumonia as compared with thickened liquids in patients who have demonstrated aspiration of thin liquids.

DATA SOURCES

Seven electronic databases, one clinical register, and three conference archives were searched. No language or publication date restrictions were imposed. Reference lists were scanned and authors and experts in the field were contacted.

REVIEW METHODS

A blind review was performed by two reviewers for published or unpublished randomized controlled trials and prospective non-randomized trials comparing the incidence of pneumonia with intake of thin liquids plus safety strategies vs. thickened liquids in adult patients who aspirated on thin liquids. The data were extracted from included studies. Odds ratios (OR) for pneumonia were calculated from the extracted data. Risk of bias was also assessed with the included published trials.

RESULTS

Seven studies out of 2465 studies including 650 patients met the inclusion criteria. All of the seven studies excluded patients with more than one known risk factor for pneumonia. Six studies compared thin water protocols to thickened liquids for pneumonia prevention. A meta-analysis was done on the six studies, showing no significant difference for pneumonia risk (OR = 0.82; 95% CI = 0.05-13.42; p = 0.89).

CONCLUSIONS

There was no significant difference in the risk of pneumonia in aspirating patients who took thin liquids with safety strategies compared with those who took thickened liquids only. This result, however, is generalizable only for patients with low risk of pneumonia.
