We have now concluded our investigation for the complaint received.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.A complaints history review was carried out using the lot and part numbers provided, there have been no further complaints reported with this issue in the past four years.It was reported that the product was used for treatment.During treatment the adhesion of the dressing was found to be low.The patient is reported to be prone to high perspiration.As with all adhesive products moisture on the skin may affect the adhesive performance of the dressing.As no samples were returned, a thorough product evaluation could not be carried out.Low adhesion may also be caused by adhesion levels of the raw material used to make the film of this dressing.There are various controls in place during the manufacturing process of both the raw material and the dressing to identify when the adhesion is not in acceptable range, as per the product specification.There are also regular tests carried out to monitor the finished product.On this occasion we have been unable to confirm the failure mode and were subsequently unable to identify a definitive root cause.We have been unable to confirm a relationship between the reported event and the device.No further actions by smith and nephew are deemed necessary at this stage.However, we will continue to monitor for any adverse trends relating to this product range.Smith and nephew acknowledge customer concern and are continually investigating ways to develop and improve our products.
