COST BENEFITS OF USING SOFT-FOAM DRESSINGS IN ACUTE AND CHRONIC<br />
WOUNDS<br />
Michelle Proudman 1<br />
1 Pennine Acute NHS Trust (Manchester, United Kingdom).<br />
Aim: This abstract presents the clinical and cost benefits of using a range of soft-foam<br />
dressings* in a range of acute and chronic wounds.<br />
Method: Twelve patients were included. Evaluation parameters included<br />
• previous dressing used/number of dressing changes per week<br />
• number of test dressing changes required per week<br />
• wound evolution<br />
Results: Three wounds healed. Average number of dressing changes per week using<br />
pre-evaluation dressings was 4.25; after three weeks using test dressing, this fell to 2.1/<br />
week. For all 12 wounds, accounting for the cost of the dressing and nursing time, the<br />
pre-evaluati3on average cost was £1,893.61/week. After using the test dressings, this<br />
reduced to an average of £781.63/week, a saving of £1,111.98/week (Table 1*).<br />
In chronic wounds and those that did not heal during the evaluation, the average number<br />
of dressing changes per week was 4.3 (pre-evaluation), average weekly cost £1,101.35.<br />
After 3 weeks of test dressings use, this reduced to an average of 2.5 dressing changes/<br />
week, average weekly cost £565.08, a saving of £436.27 per week (Table 2*).<br />
Conclusion: This small evaluation demonstrated that the test dressings have both<br />
clinical and cost benefits. Clinically, they managed wound exudate and pain. Costs<br />
savings were also realised; across all wounds, an average weekly saving of £1,111.98<br />
was made and in chronic wounds, an average weekly saving of £436.27 was<br />
demonstrated.<br />

INVESTIGATING THE ABILITY OF SILICONE COATED WOUND CONTACT LAYERS<br />
TO DELIVER NPWT EFFECTIVELY TO THE WOUND BED IN A PORCINE SOFT<br />
TISSUE EX-VIVO MODEL<br />
Emma Cole 1<br />
1 Smith and Nephew (Hull, United Kingdom).<br />
Aim: Wound Contact Layers (WCLs) are often used with NPWT (Negative Pressure<br />
Wound Therapy) to prevent tissue ingrowth into the wound filler and to make dressing<br />
removal as easy and painless as possible. WCLs must allow transmission of negative<br />
pressure to the wound bed for therapy to remain effective. The objective was to compare<br />
a new silicone WCL* to other available WCLs in their ability to permit delivery of NPWT<br />
to the wound bed.<br />
Methods: Wounds were created in a porcine ex-vivo tissue model. Pressure sensors<br />
were sutured into the wound bed to record changes in pressure. Negative pressure was<br />
applied to the wounds with and without the presence of a WCL using a commercially<br />
available NPWT system ! and foam wound filler. A range of pressures were applied from<br />
-40mmHg to -200mg and the pressures in the wound bed recorded.<br />
Results: A correlation between the set pressure and the pressure at the wound bed was<br />
observed in the absence of a WCL (R2=0.998) and in the presence of WCL<br />
A*(R2=0.9978), B† (R2=0.9939), C** (R2=0.9958) and D° (R2=0.7802). The high<br />
correlation with WCLs A*, B† and C** indicates that pressure delivered to the wound bed<br />
was not diminished.<br />
Conclusions: The new silicone WCL* performs similarly to other commercially available<br />
WCL’s in ensuring consistent delivery of NPWT to the wound bed. This study<br />
demonstrates that whilst WCLs used with NPWT offer advantages, consideration should<br />
be given to the effect the WCL has on pressure delivered.<br />
