Clinical evidence

The use of GranuFLEX ® and DuoDERM® has proven advantages to support wound healing within a protocol of care.

GranuFLEX ® and DuoDERM® are associated with improved healing in chronic wounds compared to traditional dressings1,2 and another hydrocolloid dressing.3

Day, et al. 1995

There is evidence that wound improvement is more likely with GranuFLEX ® and DuoDERM® dressings than other hydrocolloids in the management of pressure sores.

In a prospective, controlled multicentre clinical study of 52 patients it was observed that: 3

Singh, et al. 2004

In a meta-analysis of the randomised controlled trials (RCT) on hydrocolloid occlusive dressings versus conventional gauze in the healing of chronic wounds: 4

  • Analysis of the 11 papers that met the inclusion criteria found that complete healing occurred in 51% of ulcers in the hydrocolloid group compared to 38% in the conventional group

A review of economic studies in wound care management demonstrated that GranuFLEX ® and DuoDERM® dressings can reduce the overall cost of care and is cost-effective for the management of pressure sores and leg ulcers.5,6,7

Kerstein, et al. 2001

A cost study by Kerstein et al 5 concluded that:

European pressure ulcer guidelines

The European Pressure Ulcer Advisory Panel (EPUAP) and The National Pressure Ulcer Advisory Panel (NPUAP) guidelines recommend the usage of hydrocolloids for the management of pressure ulcers.

/Category/stage 1: Intact skin with non-blanchable redness of localised area usually over a bony prominence. Darkly pigmented skin may not have visible blanching; its colour may differ from the surrounding area.

"Consider using hydrocolloid dressings to protect body areas at risk for friction injury or risk of injury from tape. (Strength of Evidence=C)"8

Category/stage 2: Partial thickness loss of dermis presenting as a shallow open ulcer with a red/pink wound bed, without slough. May also present as an intact or open/ruptured serum-filled blister.

"Use hydrocolloid dressings for clean Category/Stage II pressure ulcers in body areas where they will not roll or melt. (Strength of Evidence=B)"8
