The furry seal ‘PARO’, studied at the 爱豆传媒, has already shown to bring comfort and to enhance the wellbeing of people with dementia but there were concerns about meeting the infection prevention control requirements. PARO, whilst therapeutic, offers a challenge as it can be viewed as a hard-to-clean device.

Hygiene and cleaning tests were carried out over nine months by Dr Kathy Martyn, Principal Lecturer in the university’s School of Health Sciences, on a 10-bed dementia ward run by Sussex Partnership NHS Foundation Trust.

The results, just published, show that PARO was maintained within acceptable limits for NHS Infection Control.

Lead researcher Dr Penny Dodds, who recently moved from the university to the charity Dementia UK, said: “To our knowledge, this was the first testing of the infection prevention and control aspects in the world and we are delighted with the results.

“We have demonstrated that, under controlled conditions, PARO was safe within the hospital setting for an acute care dementia unit. It is hoped that this can allay concerns from those who have been hesitant about using PARO in the NHS.

“It is anticipated that PARO will receive Medical Devices Status in the UK shortly and the Distributor is preparing PARO for the UK market – we could be seeing PARO on wards throughout the country in the not-too-distant future.

“The successful research means we can now offer our cleaning testing protocols for use. This work is ongoing and the next stage will be to see if a weekly clean can be reduced to 15 minutes.”

PARO was invented by Professor Takanori Shibata from Japan and research has shown that the seal lessens stress and anxiety, promotes social interaction, facilitates emotional expression, and improves mood and speech fluency.

PARO has built-in sensors and its artificial intelligence allows it to ‘learn’ and respond to names patients give it. It also reacts to being stroked and spoken to. It wriggles, turns to the patient, opens its big eyes and lets out a cute, appealing squeak.

Dr Dodds said: “There are similarities to pet therapy but PARO does not have the immediate association of a cat or dog and is easier to supervise.

“Unlike real pets, PARO always behaves, has rechargeable batteries, is always available – and PARO should last about 12 years.

“The most important aspect is the improvement PARO makes to a patient’s quality of life.”
