AB  - Background Continuous vital sign monitoring may identify changes sooner than current standard monitoring. Objective To investigate if the use of real time digital alerts sent to healthcare staff can improve the time taken to identify unwell patients and those with sepsis.  DesignA prospective cohort study design. Setting  West Middlesex University Hospital, UK. Participants  50 acutely unwell surgical patients admitted to hospital. Intervention Patients wore a lightweight wearable sensor measuring heart rate (HR), respiratory rate (RR) and temperature every 2 minutes whilst standard intermittent ward monitoring of vital signs was performed by nurses. Digital alerts were sent to healthcare staff from the sensor to a smartphone device. All alerts were reviewed for recruited patients to identify the exact time on the sensor in which deterioration occurred. The time to acknowledgement was then reviewed for each action and an average time to acknowledgement calculated.Results There were 50 patients recruited in the pilot study, of which there were vital sign alerts in 18 patients (36%).  The total number of vital sign alerts generated in these 18 patients was 51. Of these 51 alerts there 7 alerts for high HR (13.7%), 33 for RR (64.7%) and 11 for temperature (21.6%). Out of the 27 acknowledged alerts there were 2 alerts for HR, 17 for RR and 8 for temperature. The average time to staff acknowledgement of the notification for all alerts was 154 minutes (2.6 hours). There were some patients which had shown signs of deterioration in the cohort. The frequency of routine observation monitoring was increased in 2 cases, 3 patients were referred to a senior clinician and 2 patients were initiated on the sepsis pathway. Conclusion This study demonstrates the evaluation of digital alerts to nurses in real-time. Although not all alerts were acknowledged, deterioration on the ward observations was detected and actions were taken accordingly. Patients were started on the sepsis pathw
