Sue Hopewell Clinical Director, Tissue Viability, Medstrom

A Major Landmark

Hear from Sue Hopewell, Clinical Director (Tissue Viability) at Medstrom, on what this means: 

I am delighted that as a team we have reached the milestone of 5000 patient outcomes for Dolphin Therapy. Our team of Clinical Advisors work incredibly hard to ensure any patient that goes on Dolphin Therapy is justified, helping to bind the Medstrom ethos of right patient, right product, right time. 

“Alongside our clinical support with every Dolphin Therapy rental, is the collection of outcome data. This is a unique added-value service that we’ve been working on since 2015 and is especially important with a specialist product like Dolphin Therapy.

“The positive outcomes we’ve collected have remained consistent since 2015, which is a remarkable accomplishment and an indication of Dolphin’s outstanding and consistent performance as a specialist therapy, outside of traditional air mattresses.

“For me personally, the achievement of 5,000 outcomes helps remind me that behind every outcome is a patient we’ve made a difference for. 

“Please do take the time to read the outcome summary and if you have any questions about fluid immersion simulation, please feel free to contact me where I’d be happy to help identify suitable patients that could benefit.”

Dolphin Therapy Case Studies

5000 Outcomes: Pressure Area Care

Pressure Ulcer Risk Scores

91% of Dolphin Therapy patients had a risk score of high or very high.

Prevention Patients

98% of patients placed on Dolphin Therapy to prevent skin damage did not develop any.

Treatment Patients

Wounds healed or improved in 62% of patients placed on Dolphin Therapy for treatment.

My understanding is that Dolphin is the gold standard.

Prevention versus Treatment

Pressure ulcers are estimated to cost the NHS £3.8 million per day,4  and a recent systematic review suggested hospital-acquired pressure ulcer (HAPU) incidence was 12%.5

Patients are either placed on Dolphin Therapy to prevent skin damage (no existing wounds on placement), or to treat existing skin damage.

We know that prevention and treatment patients have similarly highly complex needs and multiple comorbidities.6 Additionally, we know how many treatment patients’ wounds from July 2021 were HAPUs, along with the categories.7

In the prevention group, 98% did not develop any skin damage. So, what would be the cost savings if 98% of Category 1, 2, 3, and 4 HAPUs in the treatment group had been prevented by earlier adoption of Dolphin Therapy?

  • Overall reduction in number of HAPUs: 599
  • Saving: £5,475,000
