Pilot testing the augmentech body position sensor on the morbidly obese patient.

Area of Science:

• Biomedical Engineering
• Clinical Monitoring Devices
• Obesity Research

Background:

• Patient repositioning is crucial for preventing complications, especially in morbidly obese individuals.
• Existing methods for monitoring patient movement can be labor-intensive and subjective.
• The Augmentech Body Position Sensor (ABPS) was developed to objectively track patient repositioning.

Purpose of the Study:

• To evaluate the accuracy of the ABPS in monitoring patient repositioning compared to human observation.
• To assess the usability and patient acceptance of the ABPS in morbidly obese individuals.
• To determine the suitability of the ABPS for measuring body movements in this specific patient population.

Main Methods:

• A descriptive study design was employed.
• Data from the ABPS placed on the thigh were compared with simultaneous video recordings of patient movements.
• Ten participants with a Body Mass Index (BMI) ≥30 undergoing polysomnography were included.

Main Results:

• A strong correspondence was found between ABPS data and data from human observation (videotapes).
• The ABPS was reported as comfortable, non-irritating, and easy to use by the participants.
• The device demonstrated reliability in measuring body position changes.

Conclusions:

• The ABPS is a potentially valuable tool for monitoring patient repositioning in morbidly obese individuals.
• Further research is recommended to explore optimal placement sites for the ABPS.
• The device shows promise for improving objective monitoring of patient mobility.
