More than 300 patients, staff, local residents and supporters flocked to this year’s Theatre and Cath Lab Open Day at Harefield Hospital for a behind-the-scenes look at the specialist care delivered every day by the hospital’s expert teams.

Visitors were invited to explore the hospital's operating theatres and cardiac catheter laboratories, where Harefield’s clinical teams showcased the innovative technology, procedures and skills involved in caring for patients with complex heart and lung conditions.

Teams from across the hospital came together to deliver interactive education stations, demonstrations, and hands-on activities, helping visitors to better understand the specialist services provided at Harefield.

Visitors were able to try surgical stitching, handle precision-made surgical tools and even try their hand with clinical robots set up to mirror some of the procedures undertaken by the hospital’s world-renowned doctors.

The event was supported by colleagues from a wide range of departments, who helped to coordinate demos, organise equipment and staffing, welcome visitors, collect feedback, provide photography and videography support, and ensure the day ran safely and smoothly.

The open day also celebrated the collaboration that underpins patient care, with clinical and non-clinical staff working together to showcase the expertise found across the hospital.
