Ackermann et al identified factors which may cause an older patient to stop driving. The authors are from Indiana University, Johns Hopkins University and Hebrew Senior Life.
Time interval: 3 years
Predictors:
(1) older age (mean age for nondrivers 78 years; mean for drivers 73 years)
(2) slow cognitive speed while performing visual attention tasks (measured with the Useful Field of View, UFOV)
(3) poor instrumental functional performance (measured using the Everyday Problems Test)
(4) fewer days driving per week (an infrequent driver)
(5) worse balance (measured with the Turn 360° Test)
The chances that the person will stop driving within 3 years increases with the number of predictors present.
Necessity and fear of losing independence may cause a person to drive for a longer period than they should.
