The Author comments on the third report from the United Kingdom Audit
of Vascular Surgical Services and Carotid Endarterectomy (CEA) and
highlights concerns that many suitable patients are not being offered
timely stroke prevention surgery. There is robust evidence that patients
with acute ischaemic stroke or TIA, in the presence of an ipsilateral
moderate or severe carotid stenosis, benefit from early carotid
endarterectomy to reduce the risk of recurrent ipsilateral stroke[2,3].
National Clinical Guidelines on Stroke, published in 2009, advised that
patients with suspected non-disabling CVA/TIA should undergo carotid
imaging within 1 week of onset of symptoms, and those with confirmed non-
disabling CVA/TIA and stable neurological symptoms if appropriate should
undergo surgery within a maximum of 2 weeks of onset symptom. Indeed the
governments National Stroke Strategy has set a target of 48 hours from
symptoms to surgery to be achieved by 2017, which will represent a major
challenge for clinicians managing stroke.
As a high-volume unit conducting carotid revascularisation we
conducted a clinical audit of our practice between 2009 and 2011 to
monitor progress towards meeting these targets and identify persistent
factors causing delay between symptoms and surgery. We found significant
improvement in the total median number of days from symptoms to surgery,
from 56 days (in 2009) to 34.5 days (in 2010), p<0.01. Particular
improvement was noted in timeframe from referral to surgery, factors which
can be controlled by the vascular surgery team, with time from referral to
surgery reducing from 24.5 days (in 2009) to 12 days (in 2010), p<0.05.
Of those patients who still did not meet the recommended 14 day timeframe
in 2010, the majority (71%) of delays could not be directly controlled by
the vascular surgical team, of these the commonest causes of delay were:
delayed referral (31%); patient initiated delays (35%), due to postponed
or cancelled appointments.
Whilst we continue to improve timeframes from referral to surgery it
is important that all clinicians managing stroke and indeed the public at
large fully engage in the campaign to raise awareness of the signs of
stroke and ensure that that prompt emergency treatment reduces the risk of
death and disability.
