Feasibility study of the Clear Water Protocol in acute stroke
This study is exploring a new way for stroke patients who have trouble swallowing to drink water safely. Often, these patients are told to avoid thin liquids to prevent water going "down the wrong way" and causing chest infections. This research, called the Clear Water Protocol, investigates if giving water between meals, after carefully cleaning the mouth, can be done safely on stroke units. The study will look into how to best introduce this practice, whether patients like it, and if it helps them stay hydrated. It will also closely monitor for any health concerns, ensuring patient safety is the top priority.
At a glance
What is this study about?
This research is looking at a new idea for stroke survivors who have difficulty swallowing, a common problem called dysphagia. Sometimes, when people have trouble swallowing, thin liquids like water can accidentally go into their lungs instead of their stomach. This can lead to chest infections. Because of this, patients are often given thickened fluids or aren't allowed to drink water between meals.
This study is testing something called the "Clear Water Protocol." The idea is that if a patient's mouth is very clean, they might be able to safely drink small amounts of plain water between meals. This study wants to understand if this protocol can be safely used in stroke units and if it would be a good option for patients. It's a "feasibility study," which means it's checking if the idea is practical and possible to carry out.
The researchers will work with health professionals and patients to figure out the best way to introduce this protocol. They will also involve about 30 patients who will try the protocol to see how they get on, how much fluid they drink, and if it affects their health. The main goal is to gather information that could help improve care and hydration for many stroke patients in the future.
Key takeaways
- Exploring safe ways for stroke patients to drink water.
- Aims to improve hydration and patient experience.
- Participation involves trying the water protocol under close supervision.
- Safety is a top priority, with careful monitoring for complications.
- Information gathered could benefit future stroke survivors.
- You can stop participating at any time.
Who may be eligible?
This study is looking for stroke survivors who are currently staying in the Acute Stroke Unit at Royal Hallamshire Hospital in Sheffield. You need to be 18 years or older and have been told by a speech therapist that you have difficulty swallowing thin liquids.
You should have been following special guidance for your swallowing (like having thickened drinks or not eating/drinking by mouth) for at least 72 hours. You also need to be able to sit up in a chair, even if you need help, and be able to participate in eating. You or a family member will need to be able to give written permission to join the study in English, Urdu, or Arabic.
However, you can't join if you already had swallowing problems before your stroke, rely fully on others for feeding, or have certain other health issues like an active chest infection, severe kidney disease, or some other serious conditions. If you cough very badly when drinking thin fluids or are due to leave the hospital very soon, you also won't be able to take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years or older?
- Are you currently cared for at the Acute Stroke Unit, Royal Hallamshire?
- Have you been told you have swallowing difficulties (dysphagia) by a therapist?
- Can you sit up in a chair, even with help?
- Can you give written permission to join, or can a family member do so on your behalf?
- Do you *not* have an active chest infection or severe kidney disease?
What does participation involve?
If you decide to take part, the study has several stages. The first parts involve reviewing existing research and talking to other healthcare professionals to understand the best ways to introduce the Clear Water Protocol. Then, about 30 patients will be asked to try drinking water between meals after their mouths have been carefully cleaned. You'll be closely watched to make sure you're safe and comfortable.
The researchers will keep track of how much water you drink and whether you develop any chest infections. You'll also be asked to complete a questionnaire about your satisfaction with being able to drink water. Later on, some patients and staff might be interviewed to understand their experiences with the protocol. The study is expected to run from December 2024 to August 2026, but your individual participation might be for a shorter period.

Common questions
What is 'dysphagia'?
Dysphagia means having difficulty swallowing. It's common after a stroke.
What is the 'Clear Water Protocol'?
It's a special way of allowing stroke patients with swallowing difficulties to drink water between meals, after their mouth is cleaned, to see if it's safe and helpful.
Will I be monitored if I take part?
Yes, you'll be closely watched to ensure your safety, especially regarding your breathing and any signs of chest infection.
Where is this study happening?
The main part of the study involving patients will take place at the Acute Stroke Unit, Royal Hallamshire Hospital in Sheffield.
Who is funding this research?
The study is being funded by the Stroke Association, which is a UK charity.
