The grading method analysed all available data: pharmacodynamic and kinetic effects, individual sensitivity, the conditions of use of each medicine, pharmacovigilance data, and experimental and crash study data . This classification system ranks the four levels of driving impairment risk from level 0 no or negligible risk to level 3 major risk.
A graded pictogram is printed on the outer packaging of all level 1 to 3 medicines, accompanied by a written warning Figure 1 : level 0, medicines with no pharmacodynamic effect likely to alter the ability to drive, according to current information 6, medicines ; level 1, medicines that do not generally impact on ability to drive, but require patient information 1, medicines ; level 2, medicines that could affect the ability to drive and require medical advice before use 1, medicines ; level 3, medicines that are known to affect the ability to drive during use medicines.
Responsibility levels in the crash were determined by a standardized method adapted from Robertson and Drummer . This method, recently validated in France using the national police database of fatal crashes  , takes into consideration the different factors likely to reduce driver responsibility: road, vehicle and driving conditions, type of accident, traffic rule obedience, and difficulty of the task involved. A score is assigned to each driver for each of these factors from 1 favourable to driving to 4 not favourable to driving.
The higher the sum of the scores, the more unfavourable the driving conditions, and thus the more likely it is that the driver will be considered not-responsible nonresponsible for the crash.
Individuals whose police reports did not contain their national ID were not included. Drivers were censored at their first involvement in a road traffic crash in order to mitigate the impact of previous crashes on medicine exposure. We compared, by logistic regression, age, gender, injury severity, vehicle type, crash location, type of police force filing the police report, alcohol level, and responsibility status between included and nonincluded individuals.
The purpose of the responsibility analysis is to compare exposure probabilities on the day of crash between responsible drivers cases and nonresponsible drivers controls . This method ensures that both cases and controls are selected from the same driving population. Statistical analyses were conducted using logistic regression.
This value was the case for all variables except for the year of crash, which was forced into the model because prescription patterns may have changed between the — and — periods. Further analyses adjusted for the presence of long-term chronic diseases.
We tested the interactions between exposure and each of the adjustment variables. Attributable fractions were estimated from the adjusted odds ratio OR estimates and the prevalence of exposure in responsible drivers . Confidence intervals CIs were computed using the bootstrap method  ,  , estimated from the 2. The case-crossover analysis consisted of a pair-matched analytical approach to compare medicine exposure during a period immediately before the crash case period with exposure during an earlier period control period for the same person .
We compared medicine exposure on the crash day with medicine exposure on the control day. The washout period between the case and control periods prevents any residual effect of an exposure in the control period on the case period. In France, the duration of a pharmacy-dispensed treatment cannot usually exceed 30 d almost without exception, i.
Data were analyzed using the SAS statistical software package, version 9. Results of the overall extraction and matching procedures for the study are illustrated in Figure 2. Ninety percent of these individuals were matched with a corresponding record in the national police database of injurious crashes This procedure led to the inclusion of 72, drivers 34, responsible and 37, nonresponsible drivers , i. Baseline characteristics of the study population are presented in Table 1. The proportion of drivers exposed to level 0, level 1, level 2, and level 3 medicines were respectively Table 3 shows the main pharmacotherapeutic drug classes used on the crash day among level 2 and 3 medicines by ATC class third level of the ATC system.
The risk of being responsible was not significant for level 1 medicines Table 4. The fraction of road traffic crashes attributable to use of levels 2 and 3 medicines was 3. The global fraction attributable to both level 2 and 3 medicines considering exposure to level 2 or level 3 medicines on the crash day was 3. The information on alcohol level was missing for 9, individuals Excluding these individuals from the univariate analysis led to no significant change in estimated ORs. We did not find any interaction between the use of level 2 or level 3 medicines and the adjustment variables.
Among level 2 medicines, the risk of being responsible for a crash was significantly higher for drugs used in diabetes A10 , antiepileptics N03 , psycholeptics N05 , psychoanaleptics N06 , and other nervous system drugs N However, after Bonferroni correction for multiple testing, the association remained significant for the last four classes only Table 5.
The Benjamini and Yekutieli procedure based on the false discovery rate led to the same conclusions. The OR for level 3 psycholeptics was similar to the OR estimated for all level 3 medicines. The risk of being responsible for a crash gradually increased from 1. Results from the case-crossover analysis showed a statistically significant association between the use of level 3 medicines and the risk of road traffic crash. There was no association with level 0, level 1, and level 2 medicines Table 7. We found evidence for an increased risk of being responsible for a road traffic crash for users of prescribed medicines defined as presenting a level 2 or level 3 risk of driving impairment according to the French medication classification system.
The fraction of road traffic crashes attributable to levels 2 and 3 medicine use was 3. The study protocol planned for the inclusion of a large range of descriptive variables related to the crash and to the drivers involved. In particular, we were able to determine the responsibility status of the driver in the crash and to adjust for key confounding factors. The responsibility analysis is a real strength of the study as it allows for the comparisons of cases and controls that share the same characteristic of being drivers.
In a previous study on the impact of illegal drug consumption, using the same national police database but limited to fatal crashes  , the same method used to determine responsibility was approved by an independent expert evaluation of responsibility. Furthermore, because the responsibility analysis relies on the assumption that nonresponsible drivers are representative of the driving population, the authors of the previous study validated the comparison of a subset of the nonresponsible individuals with the driving population in France .
Finally, the strong dose-effect relationship found in our study between alcohol level and responsibility is a further indirect validation of the method. Importantly, responsibility levels were calculated independently of alcohol and illicit drug use because of their potential interactions with medicine use. Medicine exposure was ascertained from computerized records of reimbursed prescriptions filled at the pharmacy. These data were not subject to underreporting, a major problem encountered when medicine exposure data is self-reported .
On the other hand, it is one of the study limitations that dispensing dates were considered in this study as a surrogate for actual consumption. We did not know whether the medicines were actually ingested or not. Noncompliance, which we were not able to check, would therefore result in exposure misclassification. Other studies using patient-derived data and the same dispensation database showed that the health care insurance data are reliable indicators of actual exposure for medicines used over a long time frame, less so for episodically used medicines .
We assumed that the exposure period started on the day after dispensing, as medicine dispensation on the day of crash may have been a consequence of the crash. Another limitation was that exposure to nonprescribed drugs can also not be estimated from the health care insurance database. The comparison between included drivers by means of their national ID and nonincluded drivers showed that injury severity was associated with the probability of being part of the study. Thus severely injured drivers were more likely to be included than slightly injured drivers.
Killed drivers and uninjured drivers still had lower inclusion rates. This finding can be explained by the fact that injured drivers were more likely to be admitted to hospital so their health care number was more frequently noted in the police report.
Thus, our study sample slightly overrepresented drivers injured in more severe crashes. After adjustment for crash and individual variables, including exposure to other medicines, the risk of being responsible estimate was reduced for level 3 medicines, but the association did remain significant from 1. The crude risk of being responsible measured for level 3 medicines was thus partly related to these crash and individual variables and particularly due to a co-consumption of alcohol and level 2 medicines.
The protective effect of level 0 medicines could be explained by the treatment of those minor acute diseases that might lead to an increased risk of being responsible for the crash. Surprisingly, we found no interaction between alcohol level, as reported by police forces, and medicine use, although alcohol is known to potentiate the effects of some medicines. It should be noted, however, that as the presence of alcohol is not always tested for in drivers involved in slight-injury crashes, this variable might be underestimated.
Moreover, drivers who had a negative breath test were not tested for blood alcohol concentration the legal limit in France is less than 0. Information about illicit drug use was not available in any database. The analysis was also unable to adjust for driving exposure. Whilst on medication, some people may drive less to compensate for a perceived risk.
They may also reduce their speed, pay more attention, or alter the road types that they use. The present study therefore estimated the impact of actual consumption and driving behaviors on the risk of road crash among active drivers. According to our results, the French risk classification seems relevant regarding medicines classified as levels 2 and 3 of risk for road traffic crashes. Even if the risk for level 2 and 3 medications is similar, we believe that it is useful to differentiate these two levels. The effects of level 2 medicines on driving abilities depends both on the pharmacodynamics of the drug and on individual susceptibility; medical advice is therefore needed to weigh the potential risk for each individual.

Various medicines are classified as level 2. The risks found for psycholeptics mainly anxiolytics and psychoanaleptics mainly antidepressants are concordant with others studies  ,  —  ,  , . The results for antiepileptics and other nervous system drugs in particular medicines used to treat opioid dependence are of interest and deserve further investigation.
For some of the ATC classes in level 2, the association in the responsibility analysis was not significant; however, the number of drivers exposed to antihypertensives, muscle relaxants, anti-Parkinson drugs, and antihistamines for systemic use was small. On the other hand, despite a relatively large number of individuals exposed to analgesics including opioid analgesics , we found no association with the risk of being responsible for a crash.
With level 3 medicines, the pharmacodynamic effect is predominant so all users are advised not to drive.
