Driving problems in patients with rheumatoid arthritis.
OBJECTIVE
To assess driving problems experienced by patients with rheumatoid arthritis (RA) and to examine the relationship between functional status and driving difficulty.


METHODS
Using the South Eastern Ontario Medical Organization (SEAMO) database, we identified 721 patients with RA from both urban and rural backgrounds. They completed a cross-sectional, self-administered mail survey that included the Health Assessment Questionnaire (HAQ-DI) and a co-morbidity questionnaire. We assessed the proportion of drivers versus non-drivers and patients who reported difficulty driving and who used vehicle adaptations.


RESULTS
Survey response rate was 74% and 92.2% of the subjects were current drivers. Fifty percent of the current drivers reported a little difficulty, 6.8% reported quite a bit of difficulty, and 1.5% a great deal of difficulty driving. Major reasons given for why RA limited their driving were stiffness and pain. Frequent use of mobility aids (adjusted odds ratio, OR: 5.85), HAQ-DI > or = 1 (adjusted OR: 3.40), and older age (adjusted OR: 1.04) were significant predictors of an individual with RA discontinuing driving. Higher levels of disability (HAQ-DI) were associated with a greater number of problems reported with driving and with curtailment of driving. A multivariate logistic regression determined that having a HAQ-DI > or = 1 (adjusted OR: 4.3) and difficulties sitting in the vehicle (adjusted OR: 2.9) were associated with RA limiting driving.


CONCLUSIONS
Over 50% of respondents reported some degree of difficulty driving due to their RA. Scores on HAQ-DI > or = 1 were associated with difficulty driving. Further validation of our findings needs to be performed.
