Groundbreaking Machine Learning Algorithm Accurately Predicts Mental Health Crises

Koa Health correctly predicts more than half of crises 28 days in advance, which proved clinically valuable in 64% of cases

LONDON, May 18, 2022 /PRNewswire-PRWeb/ — Koa Health, a leading global provider of digital mental healthcare solutions, and Birmingham and Solihull Mental Health NHS Foundation Trust, today announced the results of a groundbreaking machine learning algorithm that has accurately predicted mental health crises in a real-world NHS setting. The results of the study suggest that such technology could allow for early intervention and improve patient outcomes.

Koa Health developed a machine learning model that uses anonymised electronic health records to continuously monitor patients for risk of a mental health crisis. The model has been found to correctly predict more than half of the crises 28 days in advance, without a considerable false-positive rate. A following six-month study evaluated Koa Health’s algorithm’s use in clinical practice. In as many as 64% of cases, the model proved clinically valuable, either in terms of managing caseloads or mitigating the risk of crisis.

Results of the study come during Mental Health Awareness Month and follow the UK’s Mental Health Awareness Week which acknowledged the nearly one billion people worldwide who live with a mental disorder. With the global mental health emergency considerably exacerbated by the COVID-19 pandemic, healthcare systems face a growing demand for mental health services and seek solutions to allow for preventative measures. Koa Health is exploring the incorporation of crisis prediction into its comprehensive mental health service as part of its aim to use technology to radically improve access to high-quality support for mental health. The next step is to validate the model in other health systems and to undertake the larger-scale studies that will be required to obtain regulatory approval.

Dr. Oliver Harrison, CEO of Koa Health says, “Working as an NHS psychiatrist, I saw too many people arrive in our services through the Accident and Emergency Department. By the time we saw them, they were usually very sick and had often experienced problems with their relationships, finances, employment, and housing. Putting the pieces back together was almost always expensive, time-consuming, and painful for the people involved. We were delighted to be chosen as a Wave 1 NHS Test Bed to partner with Birmingham and Solihull NHS Mental Health Foundation Trust. We shared a vision of moving from reactive care – driven by crisis – to proactive care – driven by prediction and prevention. We have delivered outstanding results in this trial and look forward to continuing the development work. We believe this is the future of mental healthcare in the UK and worldwide.”

Dr. Aleksandar Matic, Koa Health’s R&D Director says, “Prevention is widely seen as the holy grail of treating mental health problems. Using AI to predict mental health crises can enable timely and proactive instead of reactive interventions to mitigate or prevent mental health crises and truly help both patients and healthcare systems. We were so excited when the results from the clinical implementation of our model suggested that our predictions may have indeed prevented more serious symptoms. Providing the right intervention at the right time sits at the core of Koa’s approach.”

About the Study
The study – the results of which have now been published in the journal Nature Medicine – was conducted by Koa Health using anonymised electronic health record data* collected over seven years (2012–2018) from 17,122 patients. Using the data, Koa Health was able to develop a unique machine learning algorithm which it used to evaluate how accurately it could continuously predict the risk of a mental health crisis (defined as “the onset of severe symptoms that require substantial healthcare resources”) over a 28 day period.

Koa Health went on to evaluate the crisis prediction algorithm in clinical practice from November 2018 to May 2019. The crisis predictions were delivered on a biweekly basis to 60 clinicians, who then evaluated whether and how such predictions helped them manage caseload priorities and mitigate the risk of crisis. Those clinicians reported the predictions to be clinically valuable in 64% of cases.

*The anonymised data remained on the Trust’s servers, which are based in Birmingham at BSMHFT headquarters, and all analysis was completed there. All data sharing between companies was bound by EU, UK and Spanish Data Protection Laws, as well as legal contracts and governance processes. The Health Research Authority (HRA) approved the study and ensured that all NHS research governance requirements were met and that patients and public interests were protected.
