abstract="Due to the rapid increase in traffic accidents caused by the old populations of ages  65-74 and more than 75 in Japan, the renewal of driver's licenses has become more  difficult following the revision of traffic laws in March 2017. As part of the  driver's license clinic at Kurashiki Heisei Hospital, the present study investigated  the status of voluntary license surrender in Okayama Prefecture of Japan. From March  2017 to December 2019, the number of voluntary surrenders increased from 5,434 to  10,284 cases, or at a rate of 0.42% to 0.80%, among license holders, with the  old-old accounting for 68%-77% of voluntary surrenders. The major reasons for  surrender were a decline in physical ability (25%-38%), a decline in driving needs  (28%-60%), and family's suggestion (14%-17%). The increase in voluntary license  surrender over these 3 years was common across all municipalities within Okayama  Prefecture, but the surrender rate was closely correlated with the aged-society rate  for both old populations of ages 65-74 and more than 75 (r = -0.5508, **p = 0.002  and r = -0.3086, p = 0.110, respectively). The driver's license clinic at Kurashiki  Heisei Hospital received 110 visits during the 3-year period, in which MCI (mild  cognitive impairment) accounted for 67% of voluntary surrenders (21.8%). The present  study suggests that the increase in the rate of voluntary license surrender during  the 3-year period was closely related to the aged-society rate in Okayama  Prefecture, and that a driver's license clinic provides a detailed dementia status  among license holders who have voluntarily surrendered their license.<p /> <p>Language: ja</p>",
