15. Mrs W complains the Trust did not investigate her symptoms correctly when she went to the ED on 12 September 2021. She also complains it did not investigate her condition properly and incorrectly discharged her on the same day. Given the fact that she was later diagnosed with a stroke it is understandable that she thinks something must have gone wrong.
16. Mrs W was struggling to walk on her left leg, her left arm felt heavy and she had tingling on the left side of her lip and chin. The examination notes said Mrs W’s symptoms were resolving, meaning they were ongoing but milder. The Trust discharged her with a diagnosis of neuropraxia, which is short term injury to a nerve. The Trust said her symptoms could be due to her sleeping on a makeshift bed which she had told staff about during her assessment.
17. Our physician adviser said based on the symptoms Mrs W had, the ED should have done a FAST assessment. The main symptoms of stroke can be remembered with the word ‘FAST’: • face – the face may have dropped on one side, the person may not be able to smile, or their mouth or eye may have dropped • arms – the person with suspected stroke may not be able to lift both arms and keep them there because of weakness or numbness in one arm • speech – their speech may be slurred or garbled, or the person may not be able to talk at all despite appearing to be awake; they may also have problems understanding what is said to them • time – it is time to dial 999 immediately if you see any of these signs or symptoms.
18. Mrs W had loss of power in her leg and arm, one of the above symptoms. Our physician adviser explained this meant she was ‘FAST positive’. The records noted Mrs W told the Trust she had a lack of feeling in her left arm and leg and also had tingling on the left side of her mouth. These are all signs that she should be considered FAST positive.
19. The ED doctor noted they did a FAST assessment but did not find Mrs W to be FAST positive and instead diagnosed neuropraxia. NICE guidelines for stroke say to suspect a stroke if a patient has one or more from: facial weakness, arm or leg weakness or speech disturbance. Mrs W had two of these symptoms with both facial and leg/arm weakness.
20. This evidence shows us the Trust failed to take the right action and identify the stroke.
21. The National Clinical Guideline for Stroke says patients with suspected stroke should be admitted directly to a hyperacute stroke service and be assessed for emergency stroke treatments by a specialist clinician, without delay.
22. NICE guidance on stroke diagnosis and initial management says:
• to offer aspirin (300 mg daily) to be started immediately • refer immediately for specialist assessment and investigation • to be seen within 24 hours of when the symptoms started • admit everyone with suspected stroke directly to a specialist acute stroke unit after initial assessment for a scan.
23. Our physician adviser said if Mrs W had been considered FAST positive on 12 September she should have been admitted to an acute stroke unit, given 300mg of aspirin and given a CT scan. This would have put Mrs W on the acute stroke pathway. They also said in their experience a diagnosis of neuropraxia should only be made if a stroke has already been eliminated as a potential option. This is because the most serious possibilities should be eliminated first.
24. The Trust did not do this and instead chose to discharge her. From this we can see the Trust failed to properly investigate Mrs W’s symptoms and so incorrectly discharged her. This is a failing. The Trust has admitted this failing in its response to Mrs W’s complaint.
25. To decide on the impact of this failing, we considered what should have happened.
26. The medical records show that when Mrs W returned to the ED on 14 September, she was admitted to a stroke ward, given 300mg of aspirin and the Trust did a CT scan. This followed the guidelines set out above, but this should have been done on Mrs W’s first visit to the ED two days earlier.
27. The CT scan showed there was a ‘lacunar infract on the right basal ganglia’ which is a sign of a stroke. This means there was a blockage in the blood vessels in the right side of Mrs W’s brain.
28. Mrs W told us she believes the Trust’s actions have caused her problems with her speech and her mobility due to long term effects on her left leg.
29. Our physician adviser said that while earlier treatment could have potentially reduced the long term effects on her health, they could not be certain that this would be the case. Unfortunately, it is not possible for us to make a direct link between what the Trust got wrong and Mrs W’s long term health condition.
30. We cannot be certain that if Mrs W had been offered treatment when she first went to the ED, that the long term effects on her speech and mobility would have been avoided. But we can see that Mrs W was denied an opportunity for a better outcome. The Trust has accepted this but has not taken action to address it. Below, we make recommendations to put this right.
