Ergonomic RFID tag placement on surgical instruments - a preliminary user study.

Area of Science:

• Biomedical Engineering
• Surgical Technology
• Human Factors Engineering

Background:

• Radio Frequency Identification (RFID) tags enable individual tracking of surgical instruments.
• Previous research identified potential RFID tag locations based on hand contact areas.
• Existing studies overlooked haptic perception and clinician interaction testing with tagged instruments.

Purpose of the Study:

• To validate prior findings through interaction-centered tests using RFID-tagged surgical instruments.
• To assess the influence of RFID tag placement on clinician handling and user satisfaction.
• To evaluate instrument design experts' ability to predict optimal RFID tag positions.

Main Methods:

• Clinicians performed interaction tests with real surgical instruments equipped with RFID tags.
• User satisfaction and handling comfort were evaluated for various tag positions.
• Instrument design experts rated tag positions and attempted to predict clinician preferences.

Main Results:

• Nearly all tested RFID tag positions reduced clinician user satisfaction compared to untagged instruments.
• RFID tags significantly influenced instrument orientation during comfortable handling, a key clinician concern.
• Instrument design experts showed limited success in predicting clinicians' preferred tag placements.

Conclusions:

• RFID tag integration negatively impacts clinician experience and instrument usability.
• Current RFID tag placement strategies require revision based on clinician feedback and haptic considerations.
• Further instrument design modifications are recommended, using clinician-identified ideal positions as a guide.
