Key result
A self-adaptive method using composite early-warning scores for patient monitoring resulted in 81% fewer readings than baseline, alongside significant reductions in alarms.
Why the study?
Wearable sensor patient monitoring is limited by massive data generation and battery power consumption, requiring strategies based on clinical status to reduce transmissions.
A novel self-adaptive method using composite early-warning scores for wearable sensors significantly reduces data transmission and power consumption while maintaining effective patient monitoring.
May reduce monitoring burden in wearables; leaves open validation in prospective trials before adoption.
Wearable sensors utilize small, low-cost, noninvasive, and wireless components. These sensors capture vital signs, allowing the monitoring of patients remotely. In this manner, they are efficient tools to enhance patient care and can be used to monitor vulnerable populations, and keep track of the development of chronic diseases, and the transmission of infectious illnesses – such as during pandemics. However, there are many challenges to monitoring patients using wearables, with massive data generation and battery power consumption being significant constraints. Strategies to reduce data generation should be applied taking into account the patient’s clinical status and health risks. Previous studies took advantage of single early-warning scores (EWS) utilized in infirmaries to detect emergencies, reduce transmissions, and be a reference for self-adaptive features embedded in the devices. Our work proposes the use of composite EWS to infer health deterioration risk, minimize data transmissions and power consumption, and reduce excessive alarms through self-adaptive features based on these scores. We also compare our method with previous studies using real patient data. Further, we propose applying self-adaptive features to sampling, processing, and transmission rates. Our method demonstrated enhanced data reduction, 81% fewer readings than the baseline, significant pruning of the number of alarms, and dynamic and automatic inference of patient risk.
