Validating a home-based proxy- and self-administered quantitative sensory testing in youth and young adults undergoing regional anesthesia for orthopedic procedures
Authors' conclusion
Proxy-/self-QST is a feasible and reliable method for assessing sensory function in youth postoperatively.
Study context
- Population
- Patients aged 8–25 scheduled for orthopedic surgery with RA15 mechanical, 15 thermal testing
- Comparison
- Proxy-/self-QST vs laboratory-based quantitative sensory testing (lab-QST)
- Outcome
- Agreement between proxy-/self-QST and lab-QST (Bland-Altman and correlation analyses)
Performance
As reported in the abstract
Agreement with lab-QST
- Proxy-/self-QST agreed with lab-QST for most parameters, particularly vibration detection and pressure pain thresholds
Further findings
Inter- and intrarater reliability
- Moderate-to-excellent across most sensory measures
Postoperative sensory changes
- Sensory loss detected immediately after surgery and heightened pain sensitivity by day 3
Acceptability
- High among participants and proxies
Safety
- No adverse events reported
