Additional information regarding sample selection. For the recruitment of slightly and moderately injured victims, a sampling plan in clusters has been set up to include one in ten people from the victims concerned in the Registry. For the slightly and moderately injured, this therefore amounted to recruitment in real time. This method of subject recruitment ensured a representativeness of the victims included in the cohort, in terms of distribution over time and across care departments and hospital appointments.The most seriously injured victims, generally hospitalized for at least 24 hours, were identified daily in the after-care departments, either during the part-time work of the survey takers in Lyon's two teaching hospitals, or via weekly telephone contact with the coordinator. Lastly, the SAMU reported all of its call-outs relating to road accidents on a daily basis.
Database objective
Main objective Main objectives
Evaluate accident consequences on the victim and his/her family (functional, social, professional and financial).
Identify the prognostic factors of a poor fate and thus define serious injured victims more effectively.
Put forward avenues for preventing consequences through suitable treatment measures.

Secondary objectives
Look more particularly into the fate of certain groups of accident victims:
- subjects who have suffered a serious injury,
- subjects who have suffered head injury (of any type of severity),
- the youngest subjects from whom even a slight head injury can have consequences on future acquisitions and therefore disrupt their development,
- elderly subjects for whom the accident can bring them a step closer to dependence.
Have figures to show the actual consequences of road accidents (and not just knowledge coming from empirical or affective data).
Inclusion criteria ESPARR is a prospective cohort study of road accident victims,
representing victims within the population of the Rhône département, based on a
systematic inclusion of accident victims in real time.
The objective was to recruit representatives of all
victims. Given the very high proportion of slightly injured victims in the Registry (around
90% - the initial objective of the subject recruitment plan was to have a different
sampling fraction depending on whether the victims were slightly injured (M.AIS1), moderately injured (M.AIS2) [1 victim
in 4] or seriously injured (all M.AIS3 subjects, i.e. 3, 4 or 5) so as to
obtain a sufficiently large sample of seriously injured victims to be able to analyze this
particular population.

Data collection method The cohort overall is subject to investigation by a basic self-questionnaire that is sent to all subjects at regular intervals. This basic information is completed for specific sub-groups by information acquired during meetings with these subjects in person:- seriously injured patients (with at least an injury AIS ≥ 3).- patients with head injuries (presenting at least one injury to the head, irrespective of itsseverity: AIS 1, 2 and more)
Classifications used AIS and ISS: Abbreviated impairment scale and injury severity score; scales for scoring injuries and their severity in accident analysisINSEE socioprofessional categoriesGlasgow Coma Scale Glasgow Outcome ScaleMIF: ASIA functional disability measurement: medullary neurological impairment scoreMarshall scale: neuroimaging traumatic brain injury score
Participant monitoring Yes

Terms of data access (charter for data provision, format of data, availability delay) • Days for presenting the results to study subjects and the professionals involved (two events have been held already)

• Special INRETS day (conference) in 2011

• Research reports: ANR, Predit, PHRC

• Scientific publications:

Two scientific articles have already been published on the ESPARR study in the Accident Analysis and Prevention journal:
1) Functional outcome after road-crash injury: Description of the ESPARR victims cohort and 6-month follow-up results.
2) Diseases, consumption of medicines and responsibility for a road crash.

Esparr has been the focus of three theses in medicine:
1) in November 2007 - Qualité de prise en charge médicale après un accident de la route dans le Rhône. Study conducted in the Rhône département as part of the ESPARR survey.
2) in November 2007 - Le syndrome de stress post traumatique dans une population d'accidentés de la route présentant un traumatisme crânien léger. Study conducted in the Rhône département as part of the ESPARR survey.
3) In 2009: le retour au travail après un accident de la route

One science thesis is underway: Les conséquences familiales, professionnelles et sociales de l’accident de la route :

• Participation in conferences: SOFMER, ADELF, automobile-Club, World Health Days,
European Congress of Physical and Rehabilitation Medicine.

• Communications for the general public: various encounters with journalists and press conferences
during the scientific days and meetings, participation in the road safety week
and in public symposia (WHO).

• Publication in the specialist press: journal of the Hospices Civils de Lyon, journal of
the UNAFTC, etc.
