Berekening van het werkelijk aantal in ziekenhuizen opgenomen verkeersgewonden, 1997-2003 : methode en resultaten van koppeling en ophoging van bestanden.

This study has determined the real number of hospital in-patients who were road crash casualties. We used two databases to calculate this: the national patient register (LMR) of all the hospitals in the Netherlands and the police registration of road crashes. We linked the 1997-2003 period of these two databases, i.e. we looked in both databases for records of the same casualty and the same crash. We used the linking method that SWOV had developed and which had last been used for the annual databases up to 1997.
