COVID-19 and Dysphagia: Considerations for the Medical SLP
Our team rounds up the latest and most relevant research regarding COVID-19 and dysphagia for SLPs on the front lines.
April 30, 2020
Here at TISLP we strive to provide SLPs with Evidence You Can Use to inform your clinical practice. We recognize that many of you are facing new constraints on the way you practice as a result of COVID-19. You may be limited by efforts to conserve personal protective equipment and to enforce strict infection control policies. You may be called on to use your knowledge and training to weigh the risks/benefits of our intervention in new ways. We are confident that you will continue to be a fierce advocate for your patients as you navigate this difficult situation.
To make this easier—and because we love connecting clinicians with science as efficiently as possible—we wanted to bring you the latest and most relevant research regarding COVID-19 and dysphagia.
The Bad News: Although it has been recommended that dysphagia screening should be mandatory for patients with critical COVID-19 post extubation, there is literally no research specifically addressing its impact on swallow function and safety.
The Good News: We can apply our existing knowledge related to dysphagia in the ICU to our current situation! To do this, we need to think critically about the symptoms of COVID-19 and the supportive therapies, and how those things might impact swallowing and aspiration risk.
With this in mind, here are some of the main considerations for increased risk of dysphagia and aspiration in patients with COVID-19:
We know that elevated respiratory rate (>25 breaths/min) and abnormal breath-swallow coordination are associated with increased risk of aspiration for both healthy and disordered populations (see here).
A quick side note: We know there has been some conversation regarding the potential impact of prone positioning during mechanical ventilation (vs. traditional supine positioning) on swallowing safety. Unfortunately, there is no research on this at this time, but if you want to hear some expert clinicians in our field discuss proning (risk of laryngeal injury; the role of the SLP), check out the additional resources at the bottom of this page.
Similarly to many of our typical patients in the ICU, patients with COVID-19 may develop neurological symptoms, such as delirium and altered level of consciousness, which can increase the risk for aspiration. And due to PPE shortages and/or staffing constraints, some of the normal supervision or assistance during meals might not be available, so paying attention to cognitive status in our assessment is as important as ever.
While many questions likely remain, we hope these considerations help you realize that the questions you are asking yourself with your patients with COVID-19 are the same questions you ask with any patient with respiratory compromise and altered mental status.
Also, these podcasts from the last month give some good perspectives:
Then for PPE issues:
In the midst of this global pandemic, we acknowledge that research is limited and things are evolving rapidly. We’ll continue to provide updates on COVID and dysphagia every single month.
Take care, Med SLPs.
