Improving door to CT scanner times for potential stroke thrombolysis candidates - The Emergency Department's role.

Abstract

Stroke thrombolysis is an important treatment in the management of acute strokes. Its' effectiveness is reliant on prompt administration after stroke onset. Disability free survival at 3-6 months increases by 10% when administered within 3 hours. There is also an economic benefit from early administration with reduced institutional care. New Scottish care standards have been introduced which suggest a target that 50% of suitable patients should receive thrombolysis within 30 minutes, and 80% within one hour 6. Processes in the Emergency Department play a key role in determining the time a patient waits between arrival and reaching the CT scanner. The project team looked at Ninewells Emergency Department times to CT scanner between May and August 2015 and found that only 20% of patients had their scan within 20 minutes, and 70% within 45 minutes. The team went on to conduct a quality improvement project. This involved initial patient mapping and short interviews with staff. A multi action approach was developed involving education in the form of emails, presentations and visual charts, and the final step was to simplify the paperwork involved. The project was conducted over 11 months and successfully reduced the times to CT, with 60% having had their CT scan within 20 minutes, and 100% within 45 minutes, with a very noticeable reduction in variation around the mean. It is hoped to take this approach forward and apply it to other processes in the department.
