This report describes an assessment of the degree of representativeness and comprehensiveness of the 1994 Road Accidents in the Private Accident Registration System (VIPORS), the first year of registration. It was determined whether victims in the thirteen hospitals that formed part of the VIPORS random sample are a good reflection of victims throughout hospitals in the Netherlands. For this purpose, the Transport Research Centre, Department for Statistics and Data Management (AVV/BG) database and the Dutch National Medical Registration (LMR) database were used. The degree of correspondence was very high, despite the fact that the VIPORS hospitals do not show a nationwide distribution across the Netherlands. Next, the 1994 VIPORS data were compared with similar data from: (1) the 1994 AVV/BG database; (2) the 1993 LMR database; and (3) from the 1992-1993 Accidents in the Netherlands (OIN) database. It is concluded that the VIPORS database gives a sufficiently representative impression of the actual nature of road accident victims who report for treatment to the First Aid hospital departments in the Netherlands. Using an `incrementation' methodology derived from the approach used by the Private Accident Registration System (PORS), the population size of road accident victims in the Netherlands can be determined.
