Event or Problem Description
It was reported that, the silicon from 100 allevyn life m 12.9x12.9 ctn10 dressings is ripping off in large portions, causing shorter wear times, inhibiting them (hcps) from following the prevention protocols, and causing re-stick issues.Incident occurred during set up/inspection.No delay, patient injury or other complications were reported.All available information has been disclosed.If additional information should become available, a supplemental report will be submitted accordingly.
Additional Manufacturer Narrative
We have now concluded our investigation into this complaint.A review of the associated batch manufacturing records did not identify any issue at the point of manufacture which may have caused or contributed to the issue highlighted by the complainant.In addition it can be confirmed that all finished product specification testing was satisfied at the point of release.The complaint history file contains further instances/ related events of the reported event.The device, intended for use in treatment, was not returned for evaluation.The wound contact surface of allevyn life is coated with a gentle silicone adhesive layer that ensures non-traumatic removal at dressing changes.The silicone adhesive will feel sticky when compared to an acrylic adhesive and is specially designed to be very soft and gentle, but can soften further, particularly at higher temperatures.This is an inherent characteristic of all of the silicone adhesives and gives them their soft / gentle properties.It is therefore possible if the product has been stored at a high temperature, this could have contributed to the reported issue.We have not been able to confirm a relationship between the event and the device or identify a definitive root cause.An ongoing internal project is being carried out into the reported failure mode, therefore no further actions are deemed necessary into this specific complaint.Smith and nephew acknowledge customer concern and are continually investigating ways to develop and improve our products.We will continue to monitor for any adverse trends relating to this product range.
