Assessing Accuracy of Clinical Diagnosis and Lesion Location in Acute Neurological Deficits - How Good Are Neurologists?

Switzerland800 participantsStarted 2017-01-10

Plain-language summary

The emergency setting for acute neurological conditions, such as stroke, is peculiar due to time pressure and limited resources for further diagnostics. Clinical skills are essential for swift and accurate bedside diagnosis and thus are the basis for early and correct treatment. This is especially evident in the context of computed tomography being the standard neuroimaging method world-wide with its limitations for detecting smaller infarcts, strokes in the posterior fossa and reduced sensitivity for stroke mimics, such as epileptic seizures or migraine aura. To date, the accuracy of clinical bedside diagnosis of stroke by neurologists verified by magnetic resonance imaging (MRI) in the emergency setting has not been studied in detail. In order to improve clinical diagnosing and future treatment it is essential to quantify the accuracy of clinical diagnosis of stroke in the emergency setting ("how good are neurologists?") and to assesses whether there are any differences between experienced staff neurologists and junior physicians.

Inclusion Criteria: * Age ≥ 18 years. * Non-refusal of "general consent" * Patients with focal clinical neurological deficits with symptom onset of \< 6 hours or wake-up strokes. Exclusion Criteria: * Interval from symptom onset to clinical examination of \> 6 hours. * Patients who do not have focal clinical neurological deficit at examination will not be included in the study.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
