Results applicable elsewhere?
During the discussion at an ESO-WSO 2020 press conference, other experts pointed out that the Catalonia group is a leader in this field, being the pioneers of the RACE score used in this study for paramedics to identify suspected large-vessel occlusions. This led to questions about the applicability of the results.
“The performance by paramedics was very good using the RACE scale, and the performance times were very impressive. Are these results applicable elsewhere?” Dr. Kiechl asked.
Dr. Ribo said the combination of the RACE score and a call with a vascular neurologist was of “great value” in identifying appropriate patients. Half of the patients selected in this way for the trial were confirmed to have a large-vessel occlusion. “That is a good result,” he added.
He noted that the performance of the local hospitals improved dramatically during the study. “They had an incentive to work on their times. They could have lost most of their stroke patients if their results came out worse. We told them they had an opportunity to show that they have a role in treating these patients, and they took that opportunity.”
Dr. Ribo said there were lessons here for those involved in acute stroke care. “When creating stroke transfer policies in local networks, the performances of individual centers need to be taken into account. If primary stroke centers are motivated and can work in a well-coordinated way and perform to within the recommended times, then they can keep receiving stroke code patients. This should be possible in most developed countries.”
Noting that the in/out time of 60 minutes at local hospitals was “very impressive,” Dr. Kiechl asked how such fast times were achieved.
Dr. Ribo responded that, to a great extent, this was because of ambulance staff. “We have trained the paramedics to anticipate a second transfer after delivering the patient to the local hospital so they can prepare for this rather than waiting for a second call.”
Dr. Ribo pointed out that there were other advantages in taking patients to local centers first. “For those that do not need to be transferred on, they will be closer to relatives. It is very difficult for the family if the patient is hundreds of miles away. And there may be a cost advantage. We did look at costs, but haven’t got that data yet.”
He said: “If local stroke centers do not treat so many stroke code patients, they will lose their expertise, and that will be detrimental to the remaining patients who are taken there. We want to try to maintain a good standard of stroke care across a decent spread of hospitals—not just a couple of major comprehensive centers,” he added.
Commenting on the study, Jesse Dawson, MD, University of Glasgow, who was chair of the plenary session at which the study was presented, said: “RACECAT is very interesting but needs a lot of thought to dissect. My takeaway is that we know that time to reperfusion is key, and we need to get these times as low as possible, but we don’t need to chase a particular care pathway. Thus, if your country/geography suits ‘drip and ship’ better, this is acceptable. If direct to endovascular is possible or you are close to such a center, then this is ideal. But within those paradigms, be as fast as possible.”
He added that results of the subgroups with regard to transfer time will be helpful.
The RACECAT study was funded by Fundacio Ictus Malaltia Vascular.
