OBJECTIVES:
To compare the efficacy of a sequential strategy combining calcium alginate and hydrocolloid dres-sings treatment of grade III or IV pressure ulcers (PUs) and the efficacy of nonsequential strategy with hydrocolloids alone.
DESIGN:
An open, randomized, multicenter parallel-group trial.
SETTING:
Twenty geriatrics hospital wards.
PARTICIPANTS:
One hundred ten older patients with grade III or IV PUs.
INTERVENTION:
The control strategy consisted of applying hydrocolloid dressings (DuodermE) for 8 weeks; the sequential strategy consisted of applying combined calcium alginate dressings (UrgoSorb) for the first 4 weeks and hydrocolloid dressings (Algoplaque) for the next 4 weeks.
MEASUREMENTS:
PU surface areas were measured weekly by ulcer tracing. The endpoints were the mean absolute surface area reduction (SAR) during the 8-week study period and the number of patients achieving a 40% or more SAR (SAR40).
RESULTS:
Fifty-seven and 53 patients were randomly allocated to sequential and control strategies respectively. Baseline patient characteristics and PU ulcer features at inclusion were similar in the two groups. Mean ± standard deviation SAR was significantly larger in the sequential treatment group (5.4 ± 5.7 cm2 and 7.6 ± 7.1 cm2 at 4 and 8 weeks) than in the control group (1.6 ± 4.9 cm2 and 3.1 ± 7.2 cm2, P < .001). In the sequential treatment group, 68.4% of the patients reached SAR40 at 4 weeks and 75.4% at 8 weeks, proportions significantly larger than in the control group (22.6% and 58.5%, respectively, P < .0001). Dressing tolerance was good in both strategies.
CONCLUSIONS:
In grade III or IV PUs, treatment using first calcium alginate dressings and then hydrocolloid dres-sings promotes faster healing than treatment with hydrocolloid dressings alone. J Am Geriatr Soc 50:269–274, 2002.
