Summary
This study explored augmented reality eyewear for cognitive aids in patient care. While the concept was promising, the prototype
Area of Science:
- Medical Informatics
- Human Factors Engineering
- Clinical Practice Improvement
Background:
- Patient care involves multiple professionals and risks, necessitating human factors analysis.
- Cognitive aids standardize tasks based on clinical guidelines to mitigate risks.
- Innovative technology is needed to improve the integration and use of cognitive aids.
Purpose of the Study:
- To design and evaluate an innovative device for facilitating cognitive aid usage.
- To assess the usability and utility of augmented reality (AR) eyewear controlled by voice commands.
Main Methods:
- A multidisciplinary team designed an AR eyewear prototype.
- Usability was assessed using the System Usability Scale (SUS) and semi-structured interviews.
- 13 anesthesiologists from three hospitals participated in the evaluation.
Main Results:
- The average SUS score was 72.5 (±15.6), indicating moderate usability.
- Participants favored the concept and suggested integrating cognitive aids for emergencies.
- The prototype's format was not favored, despite positive conceptual feedback.
Conclusions:
- Ergonomic feedback is crucial for improving the AR device.
- Further research is needed on technology adoption in clinical settings.
- The study highlights potential for AR in enhancing cognitive aid delivery.
