Thrombolysis in stroke remains underutilised in daily practice
- Several studies have shown that intravenous rt-PA is applied in <3% of patients with stroke, although up to 25% of acute ischaemic stroke patients might be eligible for thrombolysis.1
- The main obstacles to delivery of thrombolysis are:
- Lack of experience and fear of complications
- Lack of public awareness
- Poor infrastructure
- Non-availability of rt-PA at the hospital
- Delays beyond the time of eligibility for rt-PA (pre-hospital and in-hospital)
- Improvement of pre- and in-hospital procedures can increase the number of patients who receive rt-PA.2
- Elements of the stroke care system (e. g., acute care, inpatient rehabilitation, community care) are often still very demarcated in terms of definition, purpose, and accountability3
- Stroke-related care becomes fragmented caused by inadequate integration of the various facilities, agencies, and professionals that should closely collaborate in providing stroke care.4
The emergency physician’s perspective
Poor patient education:
- Almost 40% of patients admitted with a possible stroke did not know the signs, symptoms, or risk factors of a stroke.6
- Patients did not call the right number: 42% contacted their general practitioner (GP) instead of the emergency medical services, if a stroke was suspected.7
Studies have shown low thrombolysis rates for hospitals with no specific organisation or stroke protocol in place (18.2%) (OR=5.43, 95% CI: 3.84-7.73) and for those with an in-hospital restricted stroke code (37.9%) (OR=1.97, 95% CI: 1.53-2.54) compared with hospitals with a pre-notification system (54.7%).8
Studies have also shown that before the implementation of stroke protocols, the proportion of patients with an acute ischaemic stroke who received rt-PA was very low.9
The neurologist’s perspective
- Not all stroke patients have access to optimal care in practice, often because of a lack or specialist stroke facilities10
- Only 11.4% of 448 hospitals provided facilities that met the Stroke Unit Criteria assessed by the ESO in 2007.
- In two thirds of cases that receive rt-PA, the door-to-needle time is >60 min.
- Stroke expertise is mandatory to recognise stroke mimics, but experts are not always close-by.
