ANZCTR - Registration

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

This is a pilot study to assess the ability of smart phones to gather functional data on patients discharged from ICU following an admission of greater than 48 hours. An electronic medical record system will allow selection of prospective participants that meet the inclusion criteria and they will be contacted 1 month after hospital discharge by paper letter. They will be asked for consent and to install a smart phone app called the Patient Outcomes Measure (POM) that will monitor their movements and track their daily step count and the distance they travel each day for a total of 6 months The only device they will need to carry with them will be their phone and it will only monitor the participant if it is carried with them. They will also be contacted at 3 and 6 months to complete conventional surveys aimed at assessing key aspects of general health to compare to their smart phone data. The surveys should take from 30-45 minutes to complete.

Intervention code [1]

Not applicable

Comparator / control treatment

The study group will be compared to a control group consisting of the same inclusion criteria, i.e. greater than 48 hour admission to ICU, contacted the same way, by paper letter 1 month post hospital discharge but these individuals will not utilise their smart phones to collect daily step and travel data. They will be contacted at 3 and 6 months to report their general health by conventional survey methods only.

Control group

Active

Outcomes

Primary outcome [1]

To describe the number of successful app activations as assessed by a remote app data monitoring database, as a means of exploring if this method of data collection is feasible by patients being discharged from ICU

Timepoint [1]

Data will be collected remotely by an app monitoring database for 6 months where upon the trial period will cease and participants will be contacted to thank them for their involvement. Those with apps on their phones will be requested to delete the app. Follow up with conventional questionnaires will occur at 3 and 6 months post recruitment

Primary outcome [2]

To describe steps per day data for each patient with an activated POM app as measured by the POM app and collected and stored by remote app monitoring database.

Timepoint [2]

Primary outcome [3]

To describe distance-travelled per day data of participants with activated POM apps as measured by the POM app and stored on a remote app monitoring database

Timepoint [3]

Secondary outcome [1]

Assess quality of life using the European Quality of Life Assessment of 5 Domains (EQ-5D) in both the smart phone and non smart phone groups.

Timepoint [1]

Data will be collected by participants' preferred method (phone call, email or paper-mail) at 3 and 6 months where upon participants will be thanked for their time. Those with the app will be asked to delete it.

Secondary outcome [2]

To assess post traumatic stress in ICU survivors using and Impact of Events Scale; Revised (IES-R) in both the smart phone and non smart phone groups

Timepoint [2]

Secondary outcome [3]

Assess level of function utilising the World Health Organisation Disability Assessment Scale (WHODAS 2.0) in both the smart phone and non smart phone groups.

Timepoint [3]

Secondary outcome [4]

To assess depression of ICU survivors using Hospital Anxiety Depression Scale (HADS) in both the smart phone and non smart phone groups

Timepoint [4]

Statistical methods / analysis

Summative data will be presented a n (%), mean (SD) or median [IQR] depending on normality. Between group comparisons will be calculated with student t-tests or fisher exact test as appropriate.

GPS data outcomes
.1 – Time spent at home – Calculated by finding the location where the 7 longest period of inactivity took place over the last 7 days. This data is run through a clustering algorithm, the modal cluster (cluster with most points) is used to define the home nodal point, by averaging the latitude and longitude of the points in the modal cluster. The amount of time spent within 100m of this nodal point is calculated per 24 hr period and expressed as a percentage of total time in 24 hrs.
.2 – Number of locations visited – The Spatial-Temporal Density-Based Spatial Clustering of Applications with Noise (ST-DBSCAN), allows for clusters to be defined as the number of sequential GPS positions, within a pre-specified distance from the last point. We defined this a 3-points (15 minutes) with 100 m of the last point. The number of clusters or locations visited per 24 hours was recorded.
.3 – Linear distance travelled – The distance between each GPS point was measured and summed over a 24-hour period. In addition, to overcome the coastline paradox, where by the distance travelled increases with shortening GPS epoch, the distance between locations visited will also be calculated.
.4 – Minimum Convex Polygon Activity Space – A minimum convex polygon activity space is the area of a polygon that bounds the GPS locations, such that no internal angle of the polygon is greater than 180o.
.5 – Standard Deviation Ellipse Activity Space – A standard deviation ellipse is the area of an ellipse plotted from the mean longitude and latitude where the short access is formed by minimum standard deviation in longitude and latitude and the long axis is calculated by the maximum standard deviation in longitude and latitude.

Summary

Brief summary

Smart phone technology may offer an opportunity to collect data on patient outcomes following ICU admission and discharge so as to better future researchers. Using apps installed on a smart phone patient markers of patient function can be remotely monitored and automatically collated without the need for inconvenient time consuming questionnaires or clinic follow ups. The Patient Outcomes Measure app can collect such data as effectively as conventional validated historical questionnaire methods.

Data sharing statement

Will individual participant data (IPD) for this trial be available (including data dictionaries)?

No/undecided IPD sharing reason/comment

Published available data will be de-identified for security and privacy purposes. However prior to publication data will be able to be identified so that deletion of accrued data can be enacted in the event a participant wishes to drop out of the study and have their data destroyed. This data will be held securely on an SA health RAH Research network drive accessible only by research staff and not shared with other research groups this is because due to GPS monitoring of participants it is not entirely possible to de-identify raw IPD. At all times will confidentiality be upheld by the research staff.
