Therefore, it was agreed that everyone who has had a suspected TIA should have specialist assessment and investigation within 24 hours of the onset of symptoms. The committee noted the results of an original cost utility analysis, which was undertaken for this review question in the 2008 version of the stroke guideline (CG68). The analysis concluded that 'immediate assessment' had both better health outcomes and lower costs than 'assessment within a week' for the entire population of suspected TIA, without the use of a risk stratification tool. The committee acknowledged that having a TIA (or suspected TIA) is a worrying time and most people would prefer to be assessed as soon as possible. Urgent specialist assessment should ensure that people at high risk of stroke are identified early. This would allow preventative treatment to begin, which should be introduced as soon as the diagnosis of TIA is confirmed. 2022 How the recommendations might affect practice The recommendations reflect current best practice of expert assessment in a TIA clinic within 24 hours, irrespective of risk stratification using clinical scoring systems. Although everyone with a suspected TIA should be seen within 24 hours, provision of daily TIA clinics is not universal. Therefore, some areas will need to set up daily TIA clinics to provide this best practice service. The recommendations should not influence the absolute number of people who need to be subsequently assessed in a TIA clinic, but will result in all suspected TIAs being assessed with an equal degree of urgency. There are likely to be implementation challenges for some areas in providing an adequately responsive 7-days-a-week TIA clinic (or a suitable alternative 7-day service) where they currently do not exist. However, services are already being encouraged to implement TIA clinics 7 days a week.
