ICU sedation, delirium & recovery
Comparison of continuous temperature measurement methods in the intensive care unit: standard bladder catheter measurements versus non-invasive transcutaneous sensors
Authors' conclusion
In conclusion the investigated system did not meet the clinically relevant acceptance criteria and showed low precision in correctly identifying fever episodes compared to invasive temperature probes, however its main advantage lies in its continuity and non-invasiveness.
Study context
- Population
- Catheterized patients in a 20-bed surgical ICU, May–September 2023355 simultaneous measurements
- Participants
- 112 patients
- Exposure
- Wearable non-invasive transcutaneous sensor (lateral chest, clavicular) and tympanic thermometer vs bladder temperature
- Outcome
- Agreement with bladder temperature (mean absolute error, mean absolute error (MAE))
Methodological detailsprospective comparative investigation, single-centre, Measurement duration 6 hours to 6 days
- Prospective comparative investigation
- Single-centre
- Measurement duration 6 hours to 6 days
Main finding
As reported in the abstract
MAE vs bladder temperature, all patients
Observational data: associations, not effects.
Further findings
| Outcome | Lateral chest | Clavicular | Tympanic |
|---|---|---|---|
| MAE vs bladder temperature (subgroup BMI ≥ 25) | MAE 0.5 °C | MAE 0.56 °C | MAE 0.32 °C |
