An Investigation to Identify Subjects Admitted to Hospital With an Increased Risk of Developing Pressure Ulcers

Not Applicable

Completed

• Conditions: Pressure Ulcer
• Interventions: Device: PU sensor

• Registration Number: NCT05458050
• Lead Sponsor: PU sensor AB

Brief Summary

A double blind, non randomized, multicenter investigation

Detailed Description

The study consists of 2 evaluations/visits.

Evaluation/visit 1: Takes place in connection with admission to the hospital. Informed consent, inclusion and exclusion criteria are assessed as well as assessment of skin type and inspection of the entire body skin. Pregnancy test on women of childbearing potential, height, weight, blood pressure and body temperature are measured. Questions about demography, health conditions, previous illnesses, nicotine habits. Risk assessment for pressure ulcers (Modified Norton or RAPS-scale) is carried out according to the hospital usual routine. Examination with PU sensor will be performed.

Evaluation/visit 2: Takes place in connection with the discharge from the hospital or 4 weeks after visit 1 if the research subject is still hospitalized. Full body skin inspection to see possible onset of pressure ulcers. Review of the research subject's medical records as well as review of nursing notes from the hospital where the research subject has been discharged from, to find any notes about pressure ulcers. The study participation is then terminated for the research subject.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
PU Sensor examination	PU sensor	Device:PU Sensor will assess the microcirculation in sacrum with and without pressure (subject will lay on side and after that on back) the total measurement time is 5-10 minutes

Primary Outcome Measures

Name	Time	Method
Number of pressure ulcers developed between visit 1 and 2	Up to 4 weeks	This outcome is to evaluate if the subjects that have been assessed as at risk of developing pressure ulcers (using PU sensor) have actually developed pressure ulcers with a greater probability than those assessed as not at risk

Secondary Outcome Measures

Name	Time	Method
Incidence of adverse events (AEs) and adverse device effects (ADEs)	Up to 2 days	All adverse events (AEs) and adverse device effects (ADEs) incidence and severity following measurement with PU sensor up to 2 days after the baseline
