ABSTRACT

OBJECTIVE: To evaluate an advanced extracellular matrix made of ovine forestomach matrix (OFM) for healing a variety of wound types.

METHODS: Participants were enrolled from inpatient, outpatient, and home healthcare settings. The OFM was used to treat all wounds and applied to the wound bed every 3 to 7 days until closure.

RESULTS: Researchers enrolled 29 participants with 33 wounds. Average time to wound closure was 8.2 weeks, the percentage of wounds that reduced in size by 50% or more at 4 weeks was 64%, the average wound area reduction at 4 weeks was 66%, and 73% of wounds had closed at 12 weeks. No adverse effects were observed.

CONCLUSIONS: This represents the first Canadian evaluation of OFM for the treatment of wounds, and the positive healing outcomes observed could support more widespread adoption of this matrix.
