An electronic pain assessment tool developed by ePAT Technologies has been shown to be valid and reilable for people with moderate to severe dementia.
The smartphone app for pain detection captures a brief video of a person, which is analysed using facial recognition software to detect the presence of facial micro-expressions that are indicative of the presence of pain.
The study comprised 353 paired observations in 40 people with moderate to severe dementia (aged 60-98 years).
Pain assessments derived from ePAT were compared with a widely used existing pain scale (Abbey Pain Scale), and the results showed a strong positive correlation between the two tools.
Co-author of the study Jeff Hughes said being able to show the validity and reliability of an app used on a smartphone is an important step towards the adoption of more convenient technologies to derive accurate pain assessments.
This improvement at point-of-care will deliver better health outcomes for patients.
