Gloucestershire’s emergency departments have faced their busiest days ever amid recent intense heatwaves, with high humidity severely impacting hospital equipment functionality. Hospital leaders reveal that the last three heatwaves have profoundly disrupted diagnostic services.
At a health overview and scrutiny committee meeting on July 14, Kevin McNamara, chief executive of Gloucestershire Hospitals NHS Foundation Trust, explained how extreme heat and humidity have forced hospitals to rethink their seasonal preparations. He reported that during the latest heatwave, only one MRI scanner was operational across Gloucestershire Royal and Cheltenham General hospitals combined.
McNamara highlighted, “The recurring heatwaves since May have brought not just rising temperatures but also significant humidity, which has rendered some diagnostic equipment inoperable. This has forced us to bring in additional technicians to try to fix these issues, which stem from our equipment not being designed for such conditions.”

He added that this challenge is not unique to Gloucestershire; even newer hospital facilities are experiencing similar problems with their machinery. Gloucestershire faces additional difficulties due to an aging infrastructure with fragile air-handling units and leaking roofs, which result in further room closures and treatment delays.
“The practical effect is that we must prioritise emergency patients for diagnostics, inevitably increasing waiting times for others,” McNamara explained. “Managing heat risks has become a complex balancing act against an already strained diagnostic capacity.”
He emphasized that climate change necessitates new approaches to health service planning, stating, “We’ll need to start preparing for summer surges as early as January, as the impact of heatwaves now exceeds traditional winter pressures.”
Notably, emergency departments have recorded higher patient volumes during heatwaves than in previous winters. The South Western Ambulance Service has also raised alarms about escalating strain on resources caused by heat, prompting them to implement dedicated summer readiness plans similar to their winter strategies.
As Gloucestershire’s hospitals adapt to a warmer climate, these developments underscore the urgent need for health services to evolve to meet the challenges posed by extreme weather events and a changing environment.
