Prophylactic dressings to prevent sacral pressure injuries in adult patients admitted to intensive care units: A three-arm feasibility randomized controlled trial.

Background: Pressure injuries in intensive care patients are a safety issue. Specialized foam sacral prophylactic dressings prevent pressure injuries with several products available for clinicians to choose from.
Objectives: Assess the feasibility of conducting a multisite trial to test the effectiveness of two dressings versus usual care in preventing sacral pressure injuries in intensive care patients.
Methods: Using a three-arm pilot randomized trial design, adult intensive care unit patients at risk for pressure injuries were randomly allocated to the Mepilex® Sacrum dressing, the Allevyn™ Life Sacrum dressing or the control group. Daily pressure injury data were collected including a de-identified sacral photograph, which the blinded outcome assessor used to determine the study end point: a new sacral pressure injury. Pre-determined feasibility criteria were measured in terms of eligibility, recruitment, retention, intervention fidelity and missing data.
Results: From May-September 2021, we screened 602 intensive care unit adult patients for eligibility with 93 % (n = 558) excluded. Forty-four (7 %) were eligible, and all were recruited and randomized (100 %). After receipt of the intervention two participants withdrew from the study. Our final sample of 42 participants were randomly allocated to the Mepilex® (n = 12), Allevyn™ (n = 14) or control (n = 16) group. The interventions were delivered as intended and there were 11 (6 %) cases of missing outcome data. Five participants (12 %) developed a sacral pressure injury, four of whom received a sacral dressing.
Conclusions: A larger trial is feasible with minor refinement to the length of stay eligibility criterion.
Implications for Practice: Prophylactic sacral dressings are recommended for pressure injury prevention. Determining the feasibility of a larger trial to test the effectiveness of two dressings versus usual care in preventing sacral pressure injuries in intensive care patients can provide evidence to aid clinicians, policy makers and managers make value-based care decisions.
