Updated NICE Guideline on Stroke Rehabilitation in Adults

stroke-patient

The updated guidelines highlight the massive strides made towards cementing the place of orthoptists within the stroke care team.

The guidance is now that people in hospital following a stroke should be offered a specialist orthoptist assessment as soon as possible. If this is not possible before discharge, the person should be offered an urgent outpatient appointment.

This represents a real step forward, in addition to the recommendations in the National Clinical Guideline for Stroke in May, which recommended that vision screening should be completed within 72 hours, but does not specifically mention orthoptists.

Problems with vision and eye movement are common following a stroke or brain injury, affecting about 73% of people. This can have a significant impact on a person’s rehabilitation, as well as negatively affecting their quality of life.

Currently, as highlighted in the evidence review for the new Guidelines, the provision of eye care on stroke units is non-standardised and ad hoc, leading to vision problems being missed. NICE state as the basis for their recommendation that eyesight problems are more likely to be identified during an orthoptist assessment when compared to other forms of assessment.

We are hopeful that the new guidelines will encourage more consistent access to specialist orthoptist assessments, supporting earlier diagnosis of vision and eye movement problems in people who have had a stroke.

Dr Lauren Hepworth, Co-Lead of our Stroke and Neuro Rehabilitation Clinical Advisory Group said “This update of the NICE guidelines on stroke rehabilitation in adults is a positive step forward towards better system of identification and management of visual impairment post-stroke. Implementation of these guidelines will also release other members of the multi-disciplinary team from vision screening to focus on other areas of rehabilitation. There are services which already meet this new recommendation, demonstrating it is possible!”

BIOS Stroke and Neuro rehab clinical advisory group study session 4th February 2021

The first virtual stroke and neuro rehab CAG study sessions took place on the morning of 4th February 2021. The session was introduced by Alex Green, clinical lead for the CAG, who explained the workings of this new way for members to attend study sessions. He introduced Dr Lauren Hepworth, CAG academic lead, who was to be in the background organising the session and collecting questions as the presentations went on.

The morning consisted of 4 presentations and then a Q+A session. The questions were requested from members prior to the session, and delegates were also able to submit extra as the session went on.

 

Impact of COVID-19 on stroke care

Chris Ashton. Greater Manchester Integrated Stroke Delivery Network (GMISDN) Stroke Network Coordinator and former Paramedic. Chris presented data collected throughout the first lockdown of COVID-19. The data highlighted that stroke activity was reduced and there was a fall in TIA numbers. There was also an increase of people ringing 111 instead of 999 with stroke like symptoms, many resulting in emergency ambulance. Stroke is a time critical disease and data was shown that the number of stroke patients being identified in the 4-hour critical period had reduced during this time. Treatment options for stroke, thrombolysis/thrombectomy, is time sensitive and obviously a concern many patients have been missed following this data collection. He concluded by saying small ideas along with passion and support it is possible to make a difference to patient care.

Driving and visual impairment after stroke

Dr Claire Howard. Specialist Orthoptist, Salford Orthoptic Department.

Claire covered driving and vision regulations following stroke for group 1 and group 2 driving licenses. She also described the specific issues that orthoptists can deal with for those patients following a stroke. For example, monocular vision needing adaptation and diplopia being declared to the DVLA.

Exceptional cases – Claire took the group through her experience of helping patients with visual field loss following stroke, reobtain their license through the exceptional cases panel.

Life after Stroke

Stroke survivor, Janet Rockliffe, gave the group a personal account of how she dealt with the benefit system following her stroke. She highlighted a leaflet which she has developed and explained how we can help our stroke patients through this system. The leaflet is available at www.vision-research.co.uk.

Vision screening and assessment post stroke

Dr Fiona Rowe. Lecturer, University of Liverpool.

VISA – Visual Impairment Screening Assessment is a vision screening tool for MDT professionals within stroke service.

Fiona discussed how a gold standard stroke vision screening service would be an orthoptic delivered system, for each stroke patient to be given a full visual assessment. However, if this service is not available, the VISA tool can be obtained, for other service providers to use. It is available as a manual paper copy (available through University of Liverpool VISION Research Unit website) and iPad app and the assessment takes 10-30 minutes to complete, dependant on the extent of visual problems. Fiona also discussed the BIOS stroke care pathway and the orthoptic screening checklist – for stroke team to refer to orthoptist. Both of which are available on BIOS website.

Claire and Fiona also discussed the current research studies they are involved in during their presentations. Watch this space!

Q+A session

The remaining time in the session was hosted by Alex, who asked the speakers any questions that the delegates had posted into the Q+A section. Many were directed to Claire due to the nature of her talk. Driving is obviously one of the biggest issue’s that orthoptists find with their patients post stroke. The DVLA have an information booklet on their website, which can be found with this link –  https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/866655/assessing-fitness-to-drive-a-guide-for-medical-professionals.pdf

This gives the most up to date information regarding medical conditions and their impact on driving and is a useful resource for orthoptists in stroke care. Claire also highlighted the new driving pathway and exceptional cases sample letters available on the BIOS Stroke and Neuro Rehab webpage.

COVID-19 has had an impact for all, in so many different ways. This new virtual study session was a part of that. As an orthoptist in Scotland, the online session was welcomed and done well. I personally enjoyed the lack of travel and no overnight stay, allowing more time in my clinics. As with everything COVID-19 lately though, the networking with colleague’s element was greatly missed. We look forward to being able to enjoy an in person study session in the future. However, these virtual study sessions are an excellent way to allow CAG delegates to be a part of stroke study. I wonder if a mixture of online and virtual sessions going forward may be something we consider, dare I say ‘a new normal’.

New research on visual problems in acute stroke survivors

Graph-e1552490806349

A new University of Liverpool study, published in PLOS One, highlights the high incidence and prevalence of visual problems in acute stroke survivors.

A stroke is a serious life-threatening medical condition that occurs when the blood supply to part of the brain is cut off. The injury to the brain caused by a stroke can lead to widespread and long-lasting problems. Currently, visual problems are often under-reported by survivors of acute strokes.

In order to ascertain the number of new cases of Post stroke visual impairment (PSVI) and their prevalence, researchers from the University’s Department of Health Services Research, led by Professor Fiona Rowe, examined stroke assessments of 1033 patients from three stroke units over one year.

During their hospital stay each patient’s visual acuity, visual fields, ocular alignment, ocular motility, visual inattention and visual perception was assessed by an orthoptist.

The researchers found that the average number of days (post-stroke) before a visual screening was conducted was three and for a full visual assessment the average was four days.

Excluding pre-existent eye problems, the incidence of new onset visual conditions was 48% for all stroke admissions and 60% in stroke survivors.

Three quarters (752/1033 – 73%) had visual problems: 56% with impaired central vision, 40% eye movement abnormalities, 28% visual field loss, 27% visual inattention, 5% visual perceptual disorders.

Of the research Professor Rowe, said: “Incidence and prevalence of visual problems in acute stroke is alarming high, affecting over half the survivors.

“There are a wide range of visual disorders that occur following stroke and, frequently, with visual symptoms. There are equally a wide variety of treatment options available for these individuals.

“Our research shows that early visual screening and assessment is feasible and achievable within 72 hours of stroke onset and for those initially unable to be visually assessed, most can be assessed within one week of stroke onset.

“It is important to detect visual problems, regardless of whether it is pre-existent or of new onset, and disseminate the functional consequences and impact of this to patients, carers and stroke teams so this can be accounted for in activities of daily living and general mobilisation/rehabilitation. There are likely wide-ranging benefits to patients, their carers and the NHS through early and accurate identification of stroke-related visual problems.”
