Clinical evaluation of an electronic pressure-relieving mattress

A 12-month clinical evaluation of the Talley Quattro Deep Cell 2000 mattress manufactured by Talley Medical was undertaken on both a trauma and surgical ward at the Royal Devon and Exeter Hospital. An identified registered nurse coordinated the evaluation with support from tissue viability clinical nurse specialists. Data on patients, including diagnosis, Waterlow score, pressure area condition and general comments by nurses and patients, were collected. The evaluation involved 35 patients who were at high- to very-high risk of pressure sore formation. The results showed that 16 out of 40 sores healed during the evaluation period and 16 sores remained unchanged. Only one patient developed broken skin while nursed on the mattress. Seventeen patients maintained tissue integrity. Although the study was limited the results suggest that the Talley Quattro Deep Cell 2000 mattress is useful in preventing and managing pressure sores in high- to very high-risk patients.
