Pressure ulcer healing with a concentrated, fortified, collagen protein hydrolysate supplement: a randomized controlled trial.

What Was Tested

This randomized controlled trial looks at Collagen.

To compare Pressure Ulcer Scale for Healing (PUSH) scores at 8 weeks in long-term-care residents with pressure ulcers who were given standard care plus a concentrated, fortified, collagen protein hydrolysate supplement vs. residents who were given standard care plus placebo.

Who Took Part

PubMed indexes the participants as older adults, both men and women.

How the Study Was Run

The design is described as randomized, double-blind, placebo-controlled and multicenter.

The participants were allocated by chance, so the Collagen group and the comparison group should start out alike.

Neither the participants nor the staff measuring them knew who was on Collagen, so expectations could not easily colour the readings.

Some participants received a placebo instead of Collagen, giving a reference point.

More than one site took part, so the participants came from several places.

Randomized, prospective, controlled, multicenter trial at 23 long-term-care facilities in 4 states.

A total of 89 residents with Stage II, III, or IV pressure ulcers were entered into the trial; 71 residents completed the study.

Wound healing was assessed biweekly using the PUSH tool, version 3.0.

This tool categorizes pressure ulcers by surface area, exudate, and type of wound tissue.
