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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Pressure Ulcer, run by Nausicaa Medical at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 5 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of patients who developed at least one stage 2 pressure injury (time frame: 35 days after installation on the mattress (at day 35)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2026.
