In this study the representativeness and completeness of data gathered at Dutch First Aid hospital departments is evaluated. 1996 Road Accidents in the Private Accident Registration System (VIPORS) data are compared with data from other sources such as: (1) the 1996 National Accident Registration of the Netherlands Transport Research Centre, Department of Basic Data (AVV/BG); and (2) the 1996 National In-patient Register (LMR). 1996 is the third and last operational year of VIPORS. 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. The degree of correspondence was very high, despite the fact that the VIPORS hospitals do not show a nationwide distribution across The Netherlands. 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.
