Talking about a revolution: 25 years of BT and Cambridge

Cambridge and BT have been working together for more than 25 years developing new technologies, exploring human behaviour and considering how those two things come together to shape our world.

Cambridge engineers use industrial modelling techniques to help Addenbrooke’s manage COVID-19 care

̽��ֱ��work enhances the hospital’s own modelling, and provides insight into how day-to-day activities might be affected by a rise in patient numbers in the coming weeks or months.

‘Discrete event simulations’ have been worked up by a team from the ̽��ֱ��’s Department of Engineering to manage the flow of patients through hospital wards in the event of a surge in cases, and anticipate waiting times, bed availability, and equipment and staff shortages.

Lead on the simulation development, Dr Ajith Parlikad, of Cambridge’s Institute for Manufacturing, said: “It’s looking at the physical flow of patients and projecting admissions rates into the future - identifying where ‘bottlenecks’ might occur, and where the hospital might need to scale up beds, ventilators, oxygen and staff as part of their COVID-19-orientated activities.

“We started with a flow diagram of how we thought the hospital worked, then talked it through with the team at Addenbrooke’s. It was quite close to their own model, but we were able to factor in more details, such as ICU beds, ‘COVID-positive’ beds (patients with the virus who don’t require intensive care), and the initial checking and testing process when patients arrive – everything has a statistical distribution associated with it.”

As well as patient flow modelling, the Department is supporting Addenbrooke’s in a number of other ways. Industrial engineering students are volunteering their time to focus on the hospital’s oxygen supply, among other things how it might be replenished and filtered, and are also looking at how to model and optimise COVID-19 testing processes. Colleagues Tom Ridgman and Florian Urmetzer are co-ordinating the volunteer student group.

In addition, further work is beginning on modelling that will help the hospital better understand staffing level availability during disruptions such as the COVID-19 outbreak.

Duncan McFarlane, Professor in Industrial Information Engineering, said: “Two weeks ago we knew very little about hospital operations, but with close input from the hospital we’ve been able to pick from a series of industrial techniques and apply the most useful ones to this new setting. Instead of production lines we’re now looking at hospital wards, and rather than products or raw materials we are examining the flow of patients and supplies.

“ ̽��ֱ��support from the hospital has been extraordinary - especially given the level of pressure it has been operating under."

Dr Ewen Cameron, Director of Improvement and Transformation at Cambridge ̽��ֱ�� Hospitals, added: “At this time of unprecedented change for the NHS, our teams are working around the clock to set up innovative ways of working to best care for patients and protect our staff.

“ ̽��ֱ��hospital looks very different now to a few weeks ago, and we remain open to additional ideas on how to manage this crisis as best we can. New challenges require new ways of thinking, and we are hugely grateful to the Institute for Manufacturing for offering their expertise to help us beat the virus.”
