The assessment of fitness to drive after a stroke: the Nordic Stroke Driver Screening Assessment.
The British Stroke Driver Screening Assessment (SDSA) is a set of four simple cognitive tests to evaluate driving fitness in stroke patients. To evaluate its usefulness in a Scandinavian context, we adapted the tests and assessed a group of 97 stroke patients from Sweden and Norway, using a driving test as the criterion. When results were calculated according to the original method, based on a discriminant function, less than 70% of the participants were correctly classified. To improve the predictive potential, a new discriminant analysis was performed, using the scores of a subsample of 49 patients, and validated on the remaining 48 participants. In total, 78% of the patients were correctly classified, but specificity was superior to sensitivity. We conclude that the Nordic version of the SDSA is a useful instrument, provided that test scores are interpreted in a balanced manner, taking into account the possibility of compensatory traffic behavior.
