Introduction: Concerns have been raised that the nonlinear relation between crashes and
travel exposure invalidates the conventional use of crash rates to control for exposure. A …

Potentially inappropriate medications (PIMs) identified by the American Geriatrics Society
should generally be avoided by older adults because of ineffectiveness or excess risk of …

Systematic errors in pharmacoepidemiologic studies, particularly confounding, often
constitute serious concerns to inference on the causal relationship between drug use and …

OBJECTIVES: To determine the association between psychoactive medications and crash
risk in drivers aged 60 and older. DESIGN: Retrospective population‐based case‐crossover …

Objective This study examines contribution of substance use (including alcohol,
cannabinoids, stimulants, narcotics, depressants, and hallucinogens) on the probability of …

Drug use is increasingly associated with road accidents. While alcohol and illicit substances
dominate, a number of prescription drugs contribute to injury and death. Most drugs do not …

Background Loss to follow-up, if related to exposures, confounders and outcomes of interest,
may bias association estimates. We estimated the magnitude and direction of such bias in a …

Comparing exposure-based collision statistics between older drivers based on age alone
erroneously assumes a linear relationship between exposure and collision frequency …

It has been widely reported that younger and older drivers have an excess risk of causing a
road crash. Two casual hypotheses may coexist: the riskier driving behaviors and age …

Objectives: Experimental studies have shown that both depression and the use of
antidepressants may impair the ability to drive a motor vehicle. Populationbased studies …
