Data stations project

For the Dental Consumption Study (DCS), data are collected on the treatments that dentists have performed on a random 25% sample of their patients. These data have been gathered since 1997, systematic annual data are available from 1998 onwards. This data collection is facilitated by specific modules in the most commonly used software for dental practices in the Netherlands. These modules allow dentists to provide anonymised data on patient characteristics (gender, date of birth an insurance) and the universal codes of the dental treatments performed and claimed.

The Dental Practice Survey (DPS) is a biannual survey about the work situation and practice organisation of dentists. The survey was first carried out in 1995. Through a questionnaire, dentists are questioned about, among other topics, the number of working hours, the composition of the dental team and patient population, the equipment available in practice, and the workload and waiting times for different types of treatment. Initially, only written questionnaires were used, which were sent out and gathered by post. Since 2011, dentists have also had the opportunity to participate via web survey. However, to date, written responses still exceed the internet response. Therefore, questionnaires are still sent out and gathered by post. Both written and web surveys include a respondent number, which can be used to check for double participation.
-
The Survey of Recently Graduated Dentists (SRGD) was established in 2007 and is, in principle, conducted every 3 years. In SRGD, recently graduated dentists are asked about their first work experiences as dentists and their plans for future professional practice. Invitations for the first edition of this web-based questionnaire were sent by email to all dentists who had graduated in dentistry from a Dutch university in the 3 years prior to the survey. In the following editions, the ‘newly’ graduated of these institutions were invited. Due to the length of the questionnaires, the 2018 edition of SRGD was carried out in two phases. The first phase focused on the dentists’ assessment of their training; the second part focused on their work situation and their wishes for their future professional practice.
