I digested my ASHA 2014 dysphagia notes from 15 hours of courses into these five themes. I appreciate both the clarity from our physical therapy partner in item #1, as well as the tension and uncertainty underlining issues in #2-5 below. Here are the highlights:
1. Inactivity is worse than smoking, obesity, and alcohol combined per the physical therapist, Mark Richards, at Evidence-Based, Optimal Strength Exercise Parameters: Practice Considerations for Speech Therapists.
SLPs need to review exercise physiology and advocate for effective strength training:
2. A thorough Clinical Swallowing Evaluation (CSE) is valuable, necessary, and should be done prior to instrumental examinations (per James Coyle at Bedside Swallow Examinations: What They Can Do & What They Can't). Debra Suiter and Laura Sterling were co-presenters and reviewed what a CSE cannot do.
Additionally, Steven Leder, Debra Suiter and Heather Warner (at Simultaneous Clinical & Instrumental Swallow Evaluations: Findings & Consequences) reminded that the CSE should never diagnose pharyngeal dysphagia. Leder stressed the importance of the instrumental exam. For instance, CSE CANNOT evaluate:
But here's what the CSE CAN do:
The bottom-line is that we need to know why we are doing the CSE and what we expect to get out of it.
3. “Understanding the patient's disease process is one of the best tools a clinician can have,” reminded James Coyle at What's Wrong with my Patient? 2014 Update: Pulmonary, Cardiovascular, & Digestive Systems & Conditions Affecting Swallowing. For example, if we do not perform a thorough chart review as part of our CSE, we may think the patient's pneumonia is a dysphagia-related aspiration pneumonia when it is really a hematogenous pneumonia due to the patient's sepsis (bacteremia).
4.“Not everything that can be counted counts. Not everything that counts can be counted.” (William Bruce Cameron, 1963). John Rosenbek and Paula Leslie reminded us of this quote at their session: Ethics & Evidence in Practice. Leslie stated that Evidence-Based Practice (EBP) is one of the most misunderstood issues, forgetting that research is just one aspect out of three. Leslie worded EBP as: an informed clinician checks her knowledge against best available evidence and against informed patient preferences. Rosenbek warned against the “tyranny of the RCT.” In “clean” RCT studies, he asked if we tend to have difficulty finding our patients. For example, Leder noted (at Simultaneous Clinical & Instrumental Swallow Evaluations: Findings & Consequences) how his research on the 3 ounce water swallow excluded patients with tracheostomy, head and neck cancer, and dementia.We should feel a tension between data and belief, per Rosenbek.
Another example of challenges in EBP was from Catriona Steele's lecture on Diet Texture Terminology. She noted how the Protocol 201 (which is often cited as a reason to not put patients on honey thick liquid) actually used 3000 cp for honey thick as opposed to 1750 cp. This means the research was really comparing nectar thick to pudding thick. “No clear agreed upon taxonomy causes a clear risk to our patients,” per Steele.
5. “Safe and successful mealtimes are so much more than safe and successful swallowing,” per Samantha Shune at Eating is Not Just Swallowing: Redefining the “Swallowing” Process in the Elderly. This is the perfect example of how the CSE is much more than a screen of swallowing. The act of eating has an anticipatory phase. Shune showed that healthy elderly need more pre-oral time, using all proprioceptive and sensory feedback to prime the motor system. We can ensure that caregivers maximize the mealtime environment to ensure the patients have this compensatory advantage.
So here's what all this means to me and what I am taking home: Our clinical swallow evaluation is not a screen. We all agree on the limitations of the CSE. However, physicians perform clinical bedside examinations on patients and bill accordingly. They then order instrumental examinations to test their differential diagnoses. We do the same, testing our hypotheses. Per my verbal communication with Steven Leder, he does bill for an evaluation when he performs the Yale Swallow Protocol. However, he also indicated that a nurse could perform this “screening” protocol. We cannot bill for screens. What we do bedside is at a much higher cognitive level of reasoning and critical thinking than just a screen. As Rosenbek said at Ethics & Evidence in Practice: “All of this is why we have frontal lobes.”
We heard our colleagues at the sessions lament that they do not have quick access to instrumental examinations, if at all. What can we do? Some ideas for starters:
