To implement a standadized template for CT perfusion reporting in acute stroke patients in order to improve the speed and accuracy of communication of critical findings To reduce time from commencement of scanning to completion of dictation to 1 hour over an 8 month post intervention period To teach non neuroradiologists and trainees to independently interpret CT perfusion studies To evaluate the effectivess of the interventions

The baseline evaluation was conducted between 1 November 2010 and 31 October 2011. Time between patient arrival and transcribed status of the report was collected from  RIS-PACS. An 11 question online survey was created to test knowledge of acute stroke imaging and CTP. A half day workshop was conducted on March 4 and repeated March 17 for 2 groups of radiologists and trainees.. It involved didactic teaching about the evidence for advanced stroke imaging, provision of written materials, reporting template introduction, and training in CTP interpretation. The following were key outcome measures: a. Time to dicatation b. Accuracy of reports c. Completeness of reports d. Accuracy of responses to a knowledge based survey e. Utilisation of the reporting template  

23 radiologists and trainees attended a workshop and completed the pre and intervention survey. 18 completed the post intervention survey. Median arrived to transcribed time was 174 minutes (range 54 - 4209 minutes) for 154 studies audited prior to the intervention and 212.5 mins  (range 126 - 366) for 16 post intervention studies audited in the 3 weeks following the workshops. 14 / 16 reports were considered accurate by two neuroradiologists and 14/16 used the template. An average score of 4.9 out of 11 (45%) was obtained for the baseline survey prior to the workshop increasing to 6.7 out of 11 (61%) post workshop. The report content and turnaround audits will continue for the next 7 months.  

Training of non neuroradiologists in standardized acute stroke CTP interpretation is possible. Although results of CTP studies are conveyed verbally to support thrombolysis deadlines, reducing reporting times will require further  template modification and other changes to workflow.

Training of non neuroradiologists to report CTP studies will be required for triage of stroke patients to thrombolysis and intraarterial threrapies in non tertiary referral settings.
