Permanent repository link ABSTRACTThis pilot randomised controlled trial examined the effect of prophylactic dressings to minimise sacral pressure injuries in high-risk hospitalised patients and assessed feasibility criteria to inform a larger study. Eighty patients were recruited at admission points (the Emergency Department and Surgical Care Unit) or directly from participating wards in the general medical surgical setting following assessment of high risk for sacral pressure injury.Participants were randomised into either the routine care or routine care and silicone foam border dressing group. Outcome assessment comprised digital photographs of each participant's sacrum every 72 hours for evaluation by a blind-to-intervention assessor. Sixtyseven participants had at least one sacral photograph taken and assessed by a blind-tointervention assessor. Three participants were assessed as having a Stage I pressure injury.While the use of photography was effective, feasibility criteria identified challenges related to bias, blinding, weight assessment, preparation of nursing staff and sample size estimation.

Permanent ABSTRACTAim. In this paper we describe a trial protocol used to assess feasibility related to: study administration (recruitment, randomisation, retention, compliance, eligibility criteria, suitability of protocol instructions and data collection questionnaires); resource and data management (suitability of site, time and budget allocation, management of personnel and data); intervention fidelity (treatment dose, violations) and effect size.Background. Pressure injury can lead to increases in hospital length of stay and cost. The
