To ask the Scottish Government what proportion of stroke patients (a) overall and (b) in each NHS board received a brain scan within the 24-hour post-diagnosis target in 2016-17, also broken down the by the proportion of the patients that were given the scan within the target time in (i) less than four, (ii) four to eight, (iii) eight to 12 and (iv) over 12 hours.
In 2016 the Scottish Stroke Care Standard for brain scanning was made more challenging – 95%, rather than 90% of patients to have a brain scan within 24 hours of admission. In 2016, 93% of patients across Scotland with a final diagnosis of stroke had a brain scan within 24 hours compared with 91% in 2015, a statistically significant improvement.
The following tables show the numbers and percentages of patients with confirmed strokes and receiving a brain scan within 4 hours, from 4 to 8 hours, from 8 to 12 hours, from 12 to 24 hours and over 24 hours, by NHS Board of admitting hospital and NHS Board of residence.
Information is presented by NHS Board of admitting hospital for calendar year 2016, the latest full year currently published in the Scottish Stroke Improvement Programme Annual Report for 2017, available at: http://www.strokeaudit.scot.nhs.uk/Publications/Main.html.

Background Information
1. The tables are based on data drawn from eSSCA, the Scottish Stroke Care Audit (SSCA) data collection system.
2. The Scottish Stroke Improvement Programme annual report for 2017 was published on 11th July 2017.
3. Data in the annual report were extracted from eSSCA during March 2017. The data in the tables above were extracted during July 2017 and are, therefore, more up-to-date than the published data. Differences are minor but eSSCA will have changed slightly in the interim as a result of routine day-to-day data processing.
4. Confirmed stroke is based on final diagnosis. eSSCA also collects information on initial diagnosis, where a patient may be suspected of having had a stroke.
5. A small proportion of patients may have had their stroke whilst already admitted to hospital for another reason. For these patients, measurement of the time to their brain scan will start from their symptom onset date/time rather than their admission date/time.
6. The question requests NHS board. SSCA data can be assigned to the NHS board of the hospital treating the patient or the NHS board of the patient, based on their postcode of residence. The treatment and resident NHS boards may differ if, for example, patients travel to another NHS board for specialist treatment. SSCA routinely publishes information based on NHS board of treatment. The table above presents similar information based on the NHS board of residence for the patients involved.
7. The numerators upon which the percentages above are based are shown in the tables above. The denominator in each table is the number of confirmed strokes.
