    Wound contact layers (WCLs) are intended to protect and support wounds during the healing process. An open, non comparative, case series clinical evaluation was undertaken to assess the impact of these dressings on establishing an undisturbed wound environment that supports effective wound management, and to allow the establishment of limits of duration of the wear time for the experimental WCLs. The primary objectives of this clinical evaluation were to assess the ability of the WCLs to prevent tissue disturbance to the wound and surrounding skin and for the clinicians to have confidence to extend the wear time of the WCL dressings. For them to have confidence in leaving the dressings in place for extended periods, the assessment of the wound and periwound skin condition and an assessment of patient comfort was performed: assessment of wound and periwound condition in relation to tissue adherence of the dressing to the wound resulting in tissue damage/bleeding (to wound and/or periwound skin) and cellular infiltration into the WCL; assessment of patient wearing comfort and satisfaction; assessment of WCL wear time, relating to times between dressing changes as judged by the clinician. Based upon five parameters used to assess the extent to which the WCLs Atrauman, Atrauman Silicone and Atrauman Ag (HARTMANN, Germany) disturbed the underlying tissues-bleeding, wound tissue damage, periwound skin damage, tissue ingrowth and dressing adherence-the majority (>95%) of assessments indicated low or no disturbance of tissue. Over the 14 days of study assessment, the mean (±standard deviation) wear time was 7.3±1.2 days for the Atrauman group, 9.9±2.8 days for the Atrauman Silicone group, and 5.8±1.0 days for the Atrauman Ag group. All dressings were well tolerated by patients and rated highly in terms of in-use dressing performance. The results indicate that Atrauman WCLs are suitable for the management of a variety of wounds as they promote an undisturbed wound environment, including extended wear time.
