The aim of the study is to determine the clinical value of using a powered alternating pressure air overlay mattress (P-APAM) in the prevention of pressure injury (PI) in patients at medium to high risk.
This study is noncomparative, observational study.
Patients older than 18 years of age, with a medium to high risk of PI, without PI, up during the day, and lying between 15 and 20 hours per day on a specific P-APAM will be included. The study will be conducted in nursing homes, and in long-stay geriatrics department.
Patients will be followed up for 35 days. The use of the P-APAM is associated with the usual PI prevention measures. The primary outcome is the percentage of patients who will develop at least one PI of at least stage 2 on the sacrum, spine, or heel between day 0 and day 35 . Secondary endpoints are patient assessments of comfort, caregiver satisfaction, mattress noise level, and mattress safety.
