Summary
Cognitive support technologies (CSTs) improve surgical performance by reducing errors and increasing efficiency. However, ergonomic limitations and the need for more clinical data hinder their widespread adoption in surgery.
Area of Science:
- Surgical Innovation
- Human Factors Engineering
- Medical Technology
Background:
- Minimally invasive surgery increases surgeon cognitive load due to new technologies.
- Cognitive support technologies (CSTs) aim to reduce cognitive load and surgical errors.
- A systematic review of CSTs in surgery is lacking.
Approach:
- Searched literature up to May 21st, 2021, in PubMed, Web of Science, and IEEE Xplore.
- Included studies focused on reducing surgeon cognitive load, prioritizing trials with real patients.
- Assessed outcomes included surgical error, anatomical accuracy, procedural time, and patient outcomes.
Key Points:
- 37 studies showed CSTs enhance surgical performance over traditional methods.
- CSTs demonstrated decreased error rates and increased efficiency in most studies.
- CSTs achieved over 90% accuracy in identifying anatomical markers with <5mm error margin.
Conclusions:
- CSTs effectively reduce surgeon mental workload and improve surgical outcomes.
- Limited ergonomic design of current CSTs impedes clinical adoption.
- Further clinical data is required for widespread implementation of CSTs.

Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
