Boosting Knowledge to Cut Respiratory Illness Deaths

UC Engineering PhD students have created a tool, affectionately known as BOB, to help prevent the third leading cause of death in New Zealand.

Breath-to-Breath Observed Biometrics, or BOB, is being developed by Te Whare Wānanga o Waitaha University of Canterbury (UC) PhD students Ella Guy, Jaimey Clifton, and Trudy Caljé-van der Klei, who were conducting individual research and found that respiratory data is locked inside medical devices and inaccessible by everyone, including patients.

However, there was a simple solution that would provide immense value for patient monitoring, helping clinicians and patients across Aotearoa New Zealand. BOB provides real-time, high quality, breath-to-breath data, for the patient and their clinician to use.

"With BOB, more frequent monitoring can be as simple as breathing normally into the device each morning. Our research has created specialised software to interpret and send these results to your GP, providing data-driven care that isn't currently possible with appointments every one to three months," says Ella Guy.

"Current testing for respiratory illnesses, such as COPD (Chronic Obstructive Pulmonary Disorder), can take a long time and be costly. A diagnosis can take multiple visits to specialised clinics which do not have the capacity to be accessed by everyone."

Specifically, current respiratory testing can be difficult to access outside of main centres, have long waits for appointments, and be difficult for children, elderly and those with severe illnesses.

Jaimey Clifton noted over the last few years there have been significant increases in a wide range of respiratory illnesses. However, the capacity to treat these patients has not significantly changed, "this software can help provide more automated diagnosis and frequent monitoring of patients than is available today, which would reduce pressure on scarce and valuable clinician time."

"Because appointments and follow-up can be scarce due to cost and time, it is also possible patients have struggled for some time and needed a change in care. BOB offers the opportunity to track objective metrics every day and for clinicians, or even software, to notice current care is not working optimally, and then to suggest changes."
