“…Our device performances were comparable to the few similar studies that have investigated accuracy in a cuffless BP device, based on either ECG and PPG or PPG alone, against invasive measurements (12)(13)(14)(15). Three of these devices are available on the market (12-14)…”

“…It is however difficult to compare results from those directly due to heterogenicity. Our results demonstrated the least narrow LOA compared to SBP LOA of [−10, 10 mmHg] in 10 post cardiac surgery patients (Biobeat wrist watch) ( 13 ), [−11.9, 12.2 mmHg] in 23 ICU patients (Aktiia wrist band, PPG) ( 12 ), [−11, 16 mmHg] during cardiac catheterization in 17 patients (Senbiosys prototype finger ring, PPG) ( 15 ) and [−7.4, 12.8 mmHg] in 20 cardiac ICU patients during controlled short-term supine and in bed measurements (Vitaliti continuous vital signs monitor, ECG and PPG) ( 14 ). However, while not achieving as narrow LOA, our study had the most subjects, 25 vs. 10 (Biobeat, ECG and PPG), 23 (Aktiia), 17 (Senbiosys) and 20 (Vitaliti) and by far the largest number of pairwise comparisons of 7,327 compared to 4,000 (Biobeat), 326 (Aktiia), 708 (Senbiosys) and 120 (Vitaliti).…”

“…Acceptance criteria from validation standards aimed at cuff-based devices are not appropriate ( 24 ). As a consequence of lack of appropriate validation requirements regarding cuffless BP devices, many have compared against the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) criterion; mean error less than 5 mmHg and SD of errors less than 8 mmHg regarding SBP ( 12 , 14 , 15 ). Both our models satisfy this criterion as all mean errors were close to zero.…”

“…We are aware that pooling all measurement pairs across all patients may violate the Bland-Altman assumption of independent measurements (11). However, all comparable studies have pooled all measurements in Bland-Altman analyses (12)(13)(14)(15). Thus, we chose same methodology for comparative purposes.…”

ObjectiveContinuous non-invasive cuffless blood pressure (BP) monitoring may reduce adverse outcomes in hospitalized patients if accuracy is approved. We aimed to investigate accuracy of two different BP prediction models in critically ill intensive care unit (ICU) patients, using a prototype cuffless BP device based on electrocardiogram and photoplethysmography signals. We compared a pulse arrival time (PAT)-based BP model (generalized PAT-based model) derived from a general population cohort to more complex and individualized models (complex individualized models) utilizing other features of the BP sensor signals.MethodsPatients admitted to an ICU with indication of invasive BP monitoring were included. The first half of each patient’s data was used to train a subject-specific machine learning model (complex individualized models). The second half was used to estimate BP and test accuracy of both the generalized PAT-based model and the complex individualized models. A total of 7,327 measurements of 15 s epochs were included in pairwise comparisons across 25 patients.ResultsThe generalized PAT-based model achieved a mean absolute error (SD of errors) of 7.6 (7.2) mmHg, 3.3 (3.1) mmHg and 4.6 (4.4) mmHg for systolic BP, diastolic BP and mean arterial pressure (MAP) respectively. Corresponding results for the complex individualized model were 6.5 (6.7) mmHg, 3.1 (3.0) mmHg and 4.0 (4.0) mmHg. Percentage of absolute errors within 10 mmHg for the generalized model were 77.6, 96.2, and 89.6% for systolic BP, diastolic BP and MAP, respectively. Corresponding results for the individualized model were 83.8, 96.2, and 94.2%. Accuracy was significantly improved when comparing the complex individualized models to the generalized PAT-based model in systolic BP and MAP, but not diastolic BP.ConclusionA generalized PAT-based model, developed from a different population was not able to accurately track BP changes in critically ill ICU patients. Individually fitted models utilizing other cuffless BP sensor signals significantly improved accuracy, indicating that cuffless BP can be measured non-invasively, but the challenge toward generalizable models remains for future research to resolve.

Smart Rings (SRs) are user-friendly devices capable of measuring various health parameters, making them suitable for remote continuous monitoring in diverse clinical settings. Since the available evidence on the accuracy of SRs recording health data is highly heterogeneous, this systematic review, conducted in accordance with PRISMA guidelines, searched for articles evaluating the efficacy of SRs for sleep, respiratory, and cardiovascular monitoring across the PubMed, SCOPUS, and ProQuest databases. Meta-analyses were conducted for health outcomes evaluated in at least three studies with a comparable study population and design, and the same comparison device. Nineteen articles were included: eleven analyses focused on sleep quality, eight on cardiovascular parameters, and one on oxygen saturation. Studies analysing cardiovascular outcomes found a good accuracy of SRs in measuring heart rate (HR) with a mean bias of −0.4 bpms (limits of agreement (LoAs): −2.7; 1.8). The meta-analyses showed variability in SRs’ efficacy in monitoring total sleep time (mean bias: −21.3 min, LoAs: −69.9, 27.4) and REM duration (mean bias: −18.2 min, LoAs: −33.3, −3.1). The results highlighted the promising potential of SRs for HR monitoring. Further research is needed to clarify the reliability of SRs in monitoring sleep quality and their use directed to a broader range of health parameters. With further development, SRs could become valuable tools for healthcare professionals.
