I am interested in the using patient own technology in the automatic measurement of patient function. We have developed a smartphone app that remotely reports participants step and GPs data wirelessly. We have been using this technology to define activity and participation in several different populations while advancing the technology.

While its limited as an outcome measure due to limited smartphone ownership in elderly, hospital populations we are now exploring the possibility of using the step and GPS data to improve risk prediction. We are focusing on hospital readmission and peri-operative risk. Hoping not only to improve the risk prediction of mortality and readmission but to provide the patient with an individualised anticipated recovery profile using patient centred outcomes, like time spent active or time spent at home.

Use of step and location data to predict readmission to hospital and patient centred long-term outcomes in patients with heart failure.

Patients with heath failure are frequently admitted to hospital. While we can predict which patients will get readmitted within a 12 month period with relative accuracy, predicting when exactly this will happen is currently not possible.  By using patients own smartphones and an app with have created we believe that it will be possible to detect when the patient is walking less, with reduced cadence and spending more time at home. We believe this data  can be used to predict, more accurately when the patient will be admitted to hospital. We aim to recruit 200 patinets with known hearth failure and monitor them over a 12 month period and examine the data in a machine  learning environment to discover what elements of this data more accurately predict readmission.

 

The use of step and GPS data to predict readmission and patient centred long-term outcomes in patients admitted under general medicine.

Patients admitted under general medicine have a 30% chance of being readmitted to hospital within 1 year. While we can predict which patients will get readmitted within a 12-month period with relative accuracy (ROC>0.9), predicting when exactly this will happen is currently not possible.  By using patients' own smartphones and an app we have created we believe that it will be possible to detect when the patient is walking less, with reduced cadence and spending more time at home. We believe this data can be used to predict, more accurately when the patient will be admitted to hospital. We aim to recruit 300 patients admitted under general medicine at the RAH.

 

The feasibility of using a smartphone app to predict preoperative outcomes.

We are also recruiting 500 patients to a study to assess the feasibility of using smartphone data to improve the accuracy of the prediction of number of hospital free days at 90 days.

 

Summer scholarship opportunity: A literature review into the effect of Aboriginal Health placement on the future career trajectory and cultural awareness in trainee medical officers

This literature review will follow the PICO (Patient/person, Intervention/exposure, Comparison/control, Outcomes) framework:

P – Medical students and non-consultant grade doctors

I – Placement or work rotation in an Aboriginal health setting

C – Those not placed in an Aboriginal health setting

O – Career choice/cultural awareness

An outcome of this literature review will be the development of a protocol to study the effects of Aboriginal health placement in a group of interns (PGY1 Doctors). The summer scholar will have the opportunity to be involved in this outcome. Please contact me if you would like more information about this opportunity.
