Continuous Wrist‐Derived Heart Rate Correlates With m YPAS Scores and Detects Between‐Assessment Heart‐Rate Elevations in Children: A Feasibility Study
Authors' conclusion
In this small feasibility cohort, wrist-derived induction-window heart rate was associated with concurrent mYPAS scores. The majority of heart-rate elevations of undetermined cause occurred outside scheduled mYPAS assessment windows.
Study context
- Population
- Children aged 4–17 undergoing elective surgery15 analysable
- Participants
- 32 children
- Outcome
- Heart rate-mYPAS concordance and proportion of heart-rate elevations outside ±5 min of any modified Yale Preoperative Anxiety Scale (mYPAS) timepoint
- Follow-up
- Holding through induction
Methodological detailsprospective cohort, wearable wrist biosensor
- Prospective cohort
- Wearable wrist biosensor
Main finding
As reported in the abstract
Induction-window heart rate vs induction anxiety, Spearman ρ
0.55
95% CI 0.01–0.84, p = 0.034
Heart-rate elevations outside assessment windows
71%
of 90 elevations, 14 children; 95% CI 58%–80%
Children with ≥ 1 event outside all assessment windows (12 of 14)
86%
Observational data: associations, not effects.
Further findings
