An independent evaluation at Guy’s & St Thomas’ NHS Foundation Trust has found that Proximie’s Intelligence Suite can improve operating theatre efficiency, enabling teams to complete an additional robotic thoracic surgery case per day without extending theatre hours.

The findings were presented by consultant thoracic surgeon Andrea Bille at the 39th European Association for Cardio Thoracic Surgery Annual Meeting. The evaluation assessed the use of Proximie’s AI driven platform across two NHS robotic thoracic surgery lists, examining its impact on procedure times and workflow efficiency.

Proximie’s Intelligence Suite uses ambient data collection and AI analysis to provide visibility across the full operative pathway. At Guy’s & St Thomas’, this enabled surgical teams to identify inefficiencies and implement targeted workflow changes within existing theatre schedules.

The evaluation showed that average procedure times were reduced by nearly 20 minutes per case. Across a full surgical list, this resulted in close to one hour of recoverable operating room time. By identifying between 19% and 25% recoverable theatre time, the evaluation demonstrated that existing lists could accommodate an additional procedure without overruns or extended hours.

When modelled across daily lists, the recovered time translated into increased surgical capacity and potential cost efficiencies. The findings come as NHS referral to treatment waiting lists remain high, at around 7.4 million pathways, despite recent reductions linked to increased activity and system reforms. The evaluation highlighted how AI powered operational insights can help reduce cancellations, improve patient flow, and increase throughput within current capacity, particularly during periods of heightened winter pressure.

The results also reflect a broader shift towards Intelligent Operating Rooms, where AI systems ambiently capture and analyse data to support clinical decision making. This approach allows teams to identify bottlenecks, ask targeted operational questions, and implement workflow improvements that enhance efficiency and staff experience while increasing the number of patients treated.

Victoria Hatcher, VP Global Marketing & Sales EU at Proximie, said: “The findings of this independent NHS study demonstrate the measurable, real world impact our technology delivers in the operating room. By leveraging data to drive efficiency, the Intelligence Suite helps hospitals shorten procedure times, treat more patients, and reduce costs.

“This study validates and reinforces our mission to connect people, devices, and data so clinical teams can focus on delivering exceptional patient care.”

Andrea Bille, Consultant Thoracic Surgeon at Guy’s & St Thomas’ NHS Foundation Trust, said: “Our evaluation shows that when surgical teams have access to accurate, data driven insights, it can translate directly into measurable efficiency gains. By identifying small but meaningful workflow improvements, we were able to save almost an hour across each surgical list, enough time to complete an additional case without extending theatre hours.

“These results reflect tangible, real improvements that can help reduce cancellations, make better use of NHS resources, and ultimately allow more patients to receive the care they need sooner. As we head into the busy winter months, optimising theatre efficiency in this way is increasingly vital for maintaining surgical capacity and supporting the wider health system.”

Proximie is a global health technology platform focused on digitising operating and diagnostic rooms. Its Intelligence Suite uses computer vision and AI to capture real time surgical data, detect key events, and support improved operating room performance through predictive analytics and automated notifications.

Founded by Dr Nadine Hachach Haram, Proximie has been deployed in more than 500 hospitals across 50 countries and has been featured in over 20 peer reviewed publications. The company also conducts research on patient safety in surgery, including work addressing safety challenges within the NHS.
