About

In a prospective, quantitative explorative study, the risk of aspiration and penetration when swallowing solid pills (placebo) compared to a crushed placebo pill will be evaluated during a routine Fiberoptic Endoscopic Evaluation of Swallowing (FEES). The study design is thus a quasi-experimental study design with repeated measurements in the sense of a pre-posttest. Each patient undergoes a baseline examination (routine procedure) followed by the intervention (administration of three different solid pills and a crushed pill).

Full description

In the research landscape, the topic of medication intake in patients with dysphagia has generally received very little attention, which is why hardly any recommendations can be found in the current guidelines. In the national guidelines of the National Institute for Health and Care Excellence (NICE), the following paragraph was added in 2019: "People with acute stroke who are unable to take adequate nutrition, fluids and medication orally should have their oral medication reviewed to amend either the formulation or the route of administration". In the studies by Kelly and colleagues, dysphagia patients were up to three times more likely to receive an erroneous medication administration than patients without dysphagia. It is therefore currently completely unclear how solid medications can be administered safely in patients with acute dysphagia. There is a complete lack of scientific research in this area which means that the way solid medications are administered to patients with dysphagia is based solely on medical and/or nursing experience.

In everyday clinical practice, solid medications are often delivered in a crushed form to make them easier for patients to swallow. This practice is not evidence-based and has no scientific foundation. There is not a single study known to the author that has systematically investigated the swallowability of crushed medications using an instrumental procedure. Thus, there is an urgent need for research to investigate whether crushed pills can be swallowed better than solid medications by using semisolid textures. This research focuses mainly on the stroke population.

Research questions:

Based on the current state of research and the research gap presented, an overarching research question emerges: "Do patients with acute stroke and recent dysphagia also have a swallowing dysfunction for solid medications? Two subprojects are planned to answer the overall research question: A questionnaire analysis and a clinical experimental study.

The questionnaire analysis serves as a first orientation on how the topic is handled on the stroke units. One question in the questionnaire is aimed at finding out which bolus is most frequently used for the administration of medication. The clinical trial is then conducted with this result.

In a clinical quasi-experimental study, the swallowing ability of placebo medication in patients with dysphagia will be assessed using Fiberoptic Endoscopic Evaluation of Swallowing (FEES).

Primary research question "Questionnaire study" "How is medication administration on stroke units, based on dysphagia screening currently performed?" Primary research questions "Clinical study" Is there a different aspiration-penetration risk when swallowing solid medication and when swallowing crushed medication?

Methods:

In a prospective, quantitative explorative study, the risk of aspiration and penetration when swallowing solid pills (placebo) compared to a crushed placebo pill will be evaluated during a routine Fiberoptic Endoscopic Swallowing Examination (FEES). The study design is thus a quasi-experimental study design with repeated measurements in the sense of a pre-posttest. Each patient undergoes a baseline examination (routine procedure) followed by the intervention (administration of three different solid pills and a crushed pill). Randomisation is not foreseen in a quasi-experimental study or in an evaluation study.

Inclusion/exclusion criteria In this part of the study, 60 patients between 50 and 90 years of age who are admitted to the stroke unit of the neurology department at the University Hospital Tulln with an acute first insult, who have a GUSS result of less than 20 points, and who give written consent to participate in the study, are consecutively included. In addition, there must be a need for endoscopy, based on the screening result and the clinical swallowing examination.

All patients with additional neurodegenerative diseases, with re-insult, all patients in the time window of 2 hours after extubation, tracheotomy, COPD, patients with pre-existing dysphagia and with pre-existing swallowing problems with tablet swallowing are excluded. All patients who are not eligible for swallow endoscopy are also excluded.
