Gabriel Scientific has invented a pillow that may help to reduce the risk of picking up a hospital-acquired infection (HAI) such as MRSA from lying on contaminated bedding.

Gabriel Scientific’s “SleepAngel” pillow was the subject of a clinical trial by Barts and the London NHS Trust, which found its product to be more hygienic than regular hospital pillows.

Several international studies have found that hospital bedding can harbour bacteria if they become contaminated with the bodily fluids of a patient who has an infection.

While regular washing is a standard infection-control measure in all Irish hospitals, the Barts study concluded that the risk of infection from bedding is “grossly underestimated in clinical practice”, and that regular cleaning may not be enough.

The inventors of the SleepAngel pillow, Billy Navan and David Woolfsen, both worked in the health industry and saw the problems caused by superbugs in Irish hospitals. They thought the risk of infection from pillows was being overlooked in hospital hygiene policies and spent nine years creating their infection-control pillow.

Most of that time was spent searching for a material that could keep germs out of the interior stuffing while still allowing the pillow to “breathe”. A membrane normally used in heart stents was incorporated into a specially designed filter.

During the Barts study, their product was put to work alongside standard NHS pillows in UK hospital wards. Both were used on cardiac, vascular and respiratory wards and tested after three months.

The results showed high levels of contamination in the standard pillows. Some had bacteria levels which were described by Dr Arthur Tucker, who led the study, as a “bio-hazard”. Dead skin, bodily fluids and dandruff found on the pillows made them a potential source of more than 30 types of infection ranging from flu to leprosy. The SleepAngel pillows tested negative for interior contamination and were much less likely to have bacteria on the outside.
