The purpose of this study was to examine the extent to which occupational therapists (OTs) are involved in driving assessments in Sweden and how these assessments are performed. A questionnaire was sent to 154 geriatric, rehabilitation, and neurological clinics, and additionally directly to 19 OTs who had purchased a test battery specifically used for driving assessments. The response rate was 60%. Of those responding, 57% reported being involved in fitness-to-drive assessments. However, such assessments were carried out in various manners and diverse methods were used, ranging from unstandardized activity assessments to a test developed specifically for driving assessments. Only 19% used on-road driving tests as a complement to the clinical assessments. Apart from the lack of appropriate methods, the respondents said that they did not have sufficient knowledge to perform driving assessments and expressed a need for further education. In the future it seems necessary for OTs in Sweden to undergo specialized training and perform the assessments on a regular basis to maintain a high level of competence as driving assessors.

The use of the cognitive test battery Nordic Stroke Driver Screening Assessment (NorSDSA) has increased, sometimes as a stand-alone test to evaluate fitness to drive, also for non-stroke patients such as patients suffering from cognitive deficits/dementia, approaches that may be questioned. The objective of the study was to determine whether the NorSDSA could predict an on-road test result, for large sets of stroke ( n=74) and cognitive deficits/dementia participants ( n=116), respectively. The percentage of correctly classified was 62% for the stroke group and 50% for the cognitive deficits/dementia group. A discriminant analysis with pass/fail on the on-road test as grouping variable could classify 62% of the stroke participants and the cognitive deficit/dementia participants. Hence, the NorSDSA could not predict the outcome of the on-road test. Therefore, NorSDSA should not be used as a stand-alone test to determine the fitness to drive of individual participants. Also, its use with participants suffering from cognitive deficits/dementia appears to be less successful than for clients with stroke.

Eighty-five volunteer drivers, 65–85 years old, without cognitive impairments impacting on their driving were examined, in order to investigate driving errors characteristic for older drivers. In addition, any relationships between cognitive off-road and on-road tests results, the latter being the gold standard, were identified. Performance measurements included Trail Making Test (TMT), Nordic Stroke Driver Screening Assessment (NorSDSA), Useful Field of View (UFOV), self-rating driving performance and the two on-road protocols P-Drive and ROA. Some of the older drivers displayed questionable driving behaviour. In total, 21% of the participants failed the on-road assessment. Some of the specific errors were more serious than others. The most common driving errors embraced speed; exceeding the speed limit or not controlling the speed. Correlations with the P-Drive protocol were established for NorSDSA total score (weak), UFOV subtest 2 (weak), and UFOV subtest 3 (moderate). Correlations with the ROA protocol were established for UFOV subtest 2 (weak) and UFOV subtest 3 (weak). P-Drive and self ratings correlated weakly, whereas no correlation between self ratings and the ROA protocol was found. The results suggest that specific problems or errors seen in an older person's driving can actually be “normal driving behaviours”.

Background: Most older drivers continue to drive as they age. To maintain safe and independent transport, mobility is important for all individuals, but especially for older drivers.

Objective: The objective of this study was to investigate whether automatic transmission, compared with manual transmission, may improve the driving behavior of older drivers.

Method: In total, 31 older drivers (mean age 75.2 years) and 32 younger drivers – used as a control group (mean age 39.2 years) – were assessed twice on the same fixed route; once in a car with manual transmission and once in a car with automatic transmission. The cars were otherwise identical. The driving behavior was assessed with the Ryd On-Road Assessment driving protocol. Time to completion of left turns (right-hand side driving) and the impact of a distraction task were measured.

Results: The older group had more driving errors than the younger group, in both the manual and the automatic transmission car. However, and contrary to the younger drivers, automatic transmission improved the older participants’ driving behavior as demonstrated by safer speed adjustment in urban areas, greater maneuvering skills, safer lane position and driving in accordance with the speed regulations.

Conclusion: Switching to automatic transmission may be recommended for older drivers as a means to maintain safe driving and thereby the quality of their transport mobility.
