COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
We propose the development of a smart and remote monitoring and alarm system for use by hospital staff. The information (blood pressure, heart rate, pulse volume and temperature) will be collated and used to make assessment of the patients’ state of well-being.
Wireless devices such as finger clip pulse oximeter, arm-cuff blood pressure, digital ear thermometer, 2-lead ECG monitor and mobile phone communication will be employed in the proposed system to provide a user friendly and accurate vitals monitoring. The vital sings can be collected using wearable and wireless devices without interrupting the usual activities of the patients. Due to the availability of mobile phone technology among doctors and nurses, the alarms and other important information will be transmitted via a mobile phone system to the nursing station and/or to the clinician.

Early Detection / Screening
Comparator / control treatment
We will compare our results with the current practice at ward for monitoring of vitals using the ward collected early warning score (EWS) and also by comparing the ward escalations criteria during the study validation (4-6 months). This outcome will also be validated with two different methods, i.e. comparing with similar monitoring systems and by agreement using Kappa analysis.

Outcomes
Primary outcome [1] 307280 0
Early detection of deteriorating patient when compared to the traditional methods. We will use the historic early warning score data (for the entire duration of the study validation) and compare it with the validation dataset to analyse the early detection of deteriorating patients. Also, this outcome will be validated by agreement with the expert using Kappa analysis.
Timepoint [1] 307280 0
The vital signs will be collected 2-4 hourly depending on the hospital ward’s protocols until patient’s discharge. The data will be collected for 4-6 months post implementation.
Secondary outcome [1] 351356 0
Staff time saved in auto-escalation of deteriorating patient compared to the manual method. This outcome will be validated with two different methods, i.e. comparing with the current ward monitoring system and by agreement using Kappa analysis.
Timepoint [1] 351356 0
The escalation process could be generated upon every calculation of early warning score – 2-4 hourly until patient discharge.

Statistical methods / analysis
For sample size calculation it is assumed that the significance level of 0.05, power of 0.95, the effect size of 0.6 (mean difference 1.2 and SD 2). The calculation returned the sample size of 30. Also from our previous research experience (Anaesthesia monitoring using 30 patients, we propose the minimum sample size to be 30, which is achievable in one and a half year (50% of the whole project time). All the above calculations are carried out using G*Power 3.1.3 (Reference: Faul, F., Erdfelder, E., Lang, A.-G. & Buchner, A. (2007). G*Power 3: A flexible statistical power analysis program for the social, behavioral, and biomedical sciences. Behavior Research Methods, 39, 175-191).

Summary
Brief summary
We propose the development of a smart vital signs monitoring system for use by hospital staff. The information (blood pressure, heart rate, oxigen saturrration, and temperature) will be used to assess the patient’s state of wellness. The vital signs can be collected using wearable and wireless devices (vital signs devices) without interrupting the usual activities of the patients. Due to the availability of mobile phone technology among doctors and nurses, the alarms and other relevant information will be transmitted via a mobile phone to the clinicians.
Impact of the proposed system will be measured as 1) time saved in the collection of routine observations, 2) reduced time taken for alerting a critical care outreach team through the automated presentation of the Early Warning Score (EWS), and 3) reduced hospital length of stay (LOS).
