Reliability of an all-in-one wearable sensor for continuous vital signs monitoring in high-risk patients: the NIGHTINGALE clinical validation study
Authors' conclusion
The CPC12S system showed high accuracy for measurements of HR. The accuracy of RR, SpO2 were slightly overestimated and core temperature underestimated, with LoA outside the predefined clinical acceptable range. The accuracy of BP was unacceptably low.
Study context
- Population
- High-risk surgical patients admitted to high-dependency wards, 4 European hospitals3,212 h of data analysed
- Participants
- 70 patients
- Exposure
- Wearable CPC12S system vs ICU-grade monitoring
- Outcome
- Bias and 95% limits of agreement (LoA) for HR, RR, SpO2, BP and temperature

Main finding
As reported in the abstract
Bias (95% LoA), pooled analysis
- HR bias (95% limits of agreement (LoA))
- 0.0 (−3.5 to 3.4)
- RR bias (95% LoA)
- 1.5 (−3.7 to 7.5)
- SpO2 bias (95% LoA)
- 0.4 (−3.1 to 4.0)
- Blood pressure (BP) bias (LoA); BP overestimated
- 8.9 (−23.3 to 41.2)
- Temperature bias (LoA); underestimated
- −0.6 (−1.7 to 0.6)
Observational data: associations, not effects.
