Number of medications and road traffic crashes in senior Swedish drivers: a population-based matched case-control study

In this study, the authors investigated the association between risk of injurious road crashes (RTCs) and number of different medications dispensed (NDMD) to senior drivers. Using a matched case-control study of Swedish national registry data, they assessed crash victims aged 50 to 80 years involved in accidents between 2005 and 2009. Four time intervals were used for the assessment of exposure to NDMD prior to the crash date: 1–8, 1–15, 1–30 and 1–90 days. Among the results, ORs (95% CI) were seen to increase progressively with the NDMD. While the magnitude of the effect declined gradually with longer exposure periods, it remained when five or more medications were used. The authors conclude that the NDMD was associated increased likelihood of a senior driver being involved in an injurious RTC.
