Research summary
Why?
Problems with cognitive impairment are common after a stroke. The Oxford Cognitive Screen (OCS) was developed specifically for stroke survivors and is used in UK hospitals. The OCS is accessible to many stroke survivors, including those with communication difficulties. However, currently it does not accommodate for those unable to see smaller sizes of text. A study has shown that these people have difficulty completing two of the ten tasks in the OCS and 44% of stroke survivors have difficulty seeing smaller text sizes, due to stroke, a pre-existing eye condition or lack of access to their glasses in hospital.
What?
Two tasks have been adapted by increasing the line thickness to make them stand out more. This study plans to find out if people who have difficulty seeing smaller details are more able to complete the adapted version. Also, if there are no difference in scores between the original and the adapted version for those with normal vision.
How?
Currently in clinical practice each person admitted to the stroke unit has vision and cognition screened. During the OCS, stroke survivors will be asked to complete both the old and new versions of the two adapted tasks, in a random order. So possible tiredness or practice effects are cancelled out. The other eight tasks will be done in-between to create a natural gap. All stroke survivors who agree to the routine vision and cognitive screen will be included. Assent rather than written consent will be sought. To allow assessment of whether the new version can be used with stroke survivors with different levels of cognitive impairment, rather than them not being included.
So what?
The new version will allow complete and accurate cognitive screening when stroke survivors have difficulty seeing smaller text sizes. In order to provide the best care appropriate to their needs.REC name
