Case study - Clinical evaluation for specialist milkshake

Drinks manufacturers Slõ Drinks produce products for people who have dysphagia, a difficulty in swallowing. They were awarded by GM AHSN's Technology Innovation Challenge, helping to support the clinical evaluation of their latest innovation, Slõ Milkshakes. 

These drinks, a world first, are specifically designed at the right thickness to ease swallowing difficulties, whilst also providing a high calorie, nutritious supplement for people who struggle to otherwise meet their dietary needs. 

“One of our AHSN’s key priorities is to identify and support new innovations, which can lead to improved outcomes for patients."

Dr Donal O’Donoghue, Medical Director at GM AHSN

Dysphagia is a secondary symptom of some 127 different medical conditions, most commonly by stroke, but also by a range of diseases of the nervous system, cancer, or as a result of head or neck injuries. For those affected, ordinary liquids and solid foods can cause issues because they flow too fast for patients to cope with and when swallowed can lead to coughing, choking and respiratory problems. Eating and drinking can become extremely difficult and patients may become dehydrated and malnourished as a result.

Mathew Done, founder of Slõ Drinks, embarked on his business journey after asking a Speech and Language Therapist what dysphagia patients would really like. Nobody had asked it before. Sufferers had been making do with carers scooping maize-starch thickeners into their drinks. These not only made it difficult to achieve suitable consistencies, but also adversely affected the flavour and enjoyment of drinks.

“I couldn't believe in the 21st century those with dysphagia have to put up with drinks like this. They should still be able to have something enjoyable to drink – despite their condition!”
