Inter-operator and inter-device agreement and reliability of the SEM Scanner

Area of Science:

• Medical device evaluation
• Pressure ulcer prevention technology
• Biomedical engineering

Background:

• Pressure ulcers pose a significant healthcare challenge.
• Current methods for pressure ulcer detection and prevention have limitations.
• Objective tools are needed to assess tissue damage.

Purpose of the Study:

• To evaluate the inter-rater and inter-device agreement of the SEM Scanner.
• To assess the reliability of the SEM Scanner in a clinical context.
• To determine the SEM Scanner's utility in pressure ulcer prevention programs.

Main Methods:

• Thirty-one volunteers were assessed using the SEM Scanner at sternum, sacrum, and heel sites.
• Three operators used three devices, collecting multiple readings per site.
• Inter-operator and inter-device agreement and reliability were statistically analyzed.

Main Results:

• Over 3000 SEM Scanner readings were collected.
• Good agreement was observed between operators (mean differences -0.01 to 0.11).
• Inter-operator and inter-device reliability exceeded 0.80 across all sites.

Conclusions:

• The SEM Scanner exhibits high reliability and good agreement among operators and devices.
• This medical device shows potential as an objective tool for detecting pressure-induced tissue damage.
• The SEM Scanner could enhance pressure ulcer prevention strategies.
