Post Market Surveillance Study to Confirm Safety and Performance of Silicone PHMB Foam

Post Market Surveillance Study to Confirm the Safety and Performance of the Silicone Subcategory of PHMB Foam Dressings in Chronic and Acute Wounds

Post market surveillance study to confirm the safety and performance of Silicone Subcategory of PHMB Foam Dressings in Chronic and Acute Wounds.

Study Overview

• Status: Completed
• Conditions: Wound
• Intervention / Treatment: Device: ActivHeal Silicone PHMB Foam Adhesive and Non Adhesive dressing.

Detailed Description

The design of the study is an open label, multicentre, single arm trial with subjects with moderate to heavily exuding chronic and acute wounds consisting of pressure ulcers, leg ulcers, diabetic leg and foot ulcers, surgical wounds first degree superficial and partial thickness burns. The performance data from this study will support clinically meaningful rates of successful improvement in the signs and symptoms of infection, without refection during 6- week treatment and follow up period.

Description

Inclusion Criteria:

• Have a pressure ulcer, leg ulcer, diabetic leg and foot ulcer, surgical wound, first degree superficial burns or partial thickness second degree burns that are infected following assessment of signs and symptoms of infection with moderate to heavy levels of exudate.
• Have wounds at high risk of infection.
• Males or females, age 18 years or above.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Assigned intervention; ActivHeal Silicone PHMB Adhesive and Non Adhesive Foam. Subjects will undergo treatment of their chronic or acute wound as indicated in the instructions for use with ActivHeal Silicone PHMB Adhesive and Non Adhesive Foam.

Device: ActivHeal Silicone PHMB Foam Adhesive and Non Adhesive dressing.; Assigned interventions Subjects will undergo treatment of their chronic and acute wounds as indicated in instructions for use with ActivHeal Silicone PHMB Foam adhesive and Non Adhesive Foam dressings. Subjects will be evaluated as follows: Full Patient and wound assessment, Informed consent. Wound Assessment, application of dressings, (At each scheduled dressing change.) Wound Assessment, removal of dressings, (At each scheduled dressing change.) The patients will be evaluated at each dressing change over a four - six-week period (per AMS Product) or until the wound is healed to extent that the use of the ActivHeal Silicone PHMB Foam adhesive and Non Adhesive Foam dressings. is no longer indicated from the time that the patient has been recruited. The assessment of the presence and reduction of the signs and symptoms of Infection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing	Effectiveness (performance) of the ActivHeal Silicone PHMB will be evaluated for efficacy success according to the following success criteria: Reduction in signs and symptoms of infection from baseline as defined as; The change from the Investigator's opinion of infection being present to no longer being present, or; If the Investigator determines infection is still present there is improvement in severity of at least two. No worsening of any signs/ symptoms of infection at 6 weeks or if infection resolved prior to 6 weeks, that no new evidence of infection occurred during the 6 week treatment follow up.	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing.	Safety will evaluated as incidence of device related adverse events.	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of wound progression	Wound progression, assessed as the change from baseline to end of follow up. Monitoring of tissue types %,decrease in devitalised tissue, size and depth of wound.	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of pain.	Change in patient pain will be assessed using Visual Analogue Scale, VAS, from baseline to end of follow up. Pain will assessed by completion of a Visual Analogue Scale VAS (0= no pain to 10 = worst pain imaginable).	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of pain at dressing removal.	Patient pain will be assessed on removal of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing. Pain will assessed by completion of a Visual Analogue Scale, VAS(0= no pain to 10 = worst pain imaginable).	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of peri wound skin.	Changes in the peri wound skin, prevents maceration. (Allows the uptake of exudate into the dressing.) Relative score will be used to score maceration of zero (no maceration), one (minimal maceration), two (moderate maceration), and three (excessive maceration and need to withdraw patient from study). Success will be determined that over the evaluation an increased score would represent peri wound deterioration.	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of dressing removal.	Did the dressing cause trauma on removal to the wound (prevents formulation of granulation tissue growth into the pores of the dressing). Clinician and patient satisfaction with the device (ease of removal and no pain or trauma on removal) will be assessed using a likert type scale. (Very satisfied, Satisfied and not Satisfied).	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
Effectiveness of the ActivHeal Silicone PHMB foam adhesive and Non Adhesive foam dressing in terms of repositioning.	Can the dressing be repositioned and or lifted, securely placed back down. Clinician satisfaction with the device (conformability & ease of use) will be assessed using a Likert type scale. (Very satisfied, Satisfied and not Satisfied)	Immediately following initial assessment, dressing removal every 7 days follow up visits, for 6 weeks.
