| Popis: | Objective Wireless sensors for continuous monitoring of vital signs have potential to improve patient care by earlier detection of deterioration in general ward patients. We aimed to assess agreement between wireless and standard (wired) monitoring devices in patients hospitalized with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Approach Paired measurements of vital signs were recorded with 15 minutes intervals for two hours. The primary outcome was agreement between wireless and standard monitor measurements using the Bland and Altman method to calculate bias with 95% limits of agreement (LoA). We considered LoA of less than ±5 beats/min (bpm) acceptable for heart rate (HR), whereas agreement of peripheral oxygen saturation (SpO2), respiratory rate (RR), and blood pressure (BP) were acceptable if within ±3%-points, ±3 breaths/min (brpm), and ±10 mmHg, respectively. Main results 180 sample-pairs of vital signs from 20 with AECOPD patients were recorded for comparison. The wireless vs standard monitor bias was 0.03 (LoA -3.2 to 3.3) bpm for HR measurements, 1.4% (LoA -0.7 to 3.6%) for SpO2, -7.8 (LoA -22.3 to 6.8) mmHg for systolic BP and -6.2 (LoA -16.8 to 4.5) mmHg for diastolic BP. The wireless vs standard monitor bias for RR measurements was 0.75 (LoA -6.1 to 7.6) brpm. Significance Commercially available wireless monitors could accurately measure heart rate in patients admitted with AECOPD compared to standard wired monitoring. Agreement for SpO2 were borderline acceptable while agreement for RR and BP should be interpreted with caution. |
