Abstract
Abstract Background Wireless vital parameter continuous monitoring (WVPCM) is compared to regular nurse monitoring in order to provide data on the clinical and economic impact of critically ill patients (CIPs) in Internal Medicine Units (IMU). Study Design Pilot prospective randomized controlled open-label multi-center study with WIN@Hospital wearable wireless system creating alerts on portable devices (ipad). Experimental Arm: CIPs with MEWS (Modified Early Warning Score) ≥3 and/or NEWS (National Early Warning Score) ≥5 at admission underwent WCPCM over the first 72 h. Active Comparator: CIPs with MEWS ≥3 and/or NEWS ≥5 at admission undergoing regular nurse monitoring. Method Primary outcomes: Reduction of major complications (MC) from 15% to 5%. Secondary outcomes: One day reduction in length of stay (LOS); reduced nurse monitoring time; accurate patient stratification and definition of end stage disease. Results Preliminary results: Enrolled 145 and evaluable 125 patients (51 M/74 F), mean age 80.5 years, Comorbidity: Cumulative Illness Rating Scale CIRS-CI: 4, CIRS SI: 1.8. About 38% scored a BRASS (Blaylock Risk Assessment Screening Score) ≥20 indicating need for discharge planning requiring step-down care. More than 50% of patients present IIA index >3 indicating high dependency from nursing assistance. Nurses saved a minimum of 49,6 minutes to a maximum of 58,1 minutes on time spent monitoring each patient per day. A trend towards reduction of major complications in the experimental group appears to be seen (31% versus 45%). Decrease in re-admissions (7% versus 11%) and mortality (7.3% versus 23.9%) has been observed. Arrhythmic and ischemic complications detection doubled in the experimental arm. More than 30% of the patients meet the criteria defining end stage disease. Conclusion WVPCM, detecting early deterioration in CIPs, may facilitate timely response in at-risk patients, increasing safety and reducing costs.
