Clients of general practice participating in Nivel Zorgregistrs Eerste Lijn (01-01-2012-01-01-2018)

Description

This file contains data about people registered with general practitioners who participate in Nivel Zorgregistrs Eerste Lijn (NZR). These files can only be used within the CBS after the permission of Nivel, the use is associated with costs. External researchers can submit a data request via the Nivel website. After approval, Nivel will in most cases (for a fee) create a specific custom file that is focused on the research question. More information on how to access the data: > https://www.cbs.nl/nl-nl/onze-diensten/maatwerk-en-microdata/microdata-zelf-onderzoek-doen ### Methodology This file is in most cases used in combination with NZR disease episodes or NZR operations, which include the care content variables. The NZR registration includes a different number of general practice per year (roughly about 10 % of all Dutch GP practices), with the registration holder NIVEL aiming for representativeness for the Dutch population when selecting practices. The registration shall include, inter alia, data on operations and disease episodes. In addition, it contains an exit from the client administration of general practice. This file is based on this exit. Only the registered, permanent clients are included in a practice; passers-by are not part of the sample population. The file contains only those persons who are uniquely linked to the Basic Persons Registration (BRP) and have a valid RIN number (RINPERSOON=R). Until 2016, the link key was mainly used for gender, date of birth and postcode4, which could result in N-op-N links: clients with such a link are not part of this file. By using BSN as a torque key, the number of N-op-N links is almost zero as of 2016. Only uniquely connectable clients with a 1-to-1 link to the BRP are present in this end file. In addition, increased weights have been added per client for the disease episodes and operations. These elevated weights have been used to determine representative figures for the entire Dutch population for publication in StatLine tables. Because there was a bias due to the N-op-N links until 2015, and selective groups of clients were removed, a couple chance was worked until 2015. The inverse of the torque probability is a raised weight that depends on the torque keys and country of birth, and corrects for the selective removal of persons by N-op-N couplings. The inverse of the torque probability until 2015 was also the starting weight when calculating the final lift weights. As of 2016, the couple chance for almost all clients is 1 because it could be linked to BSN. For each client, each practice in which he/she was registered in the reporting year is indicated which was the most early and the most late registration quarter in that year. For clients enrolled in a practice throughout the year, these variables have values 1 and 4 respectively. Furthermore, it is indicated whether the practice has delivered appraised disease episodes and/or operations. If this is the case, any illness episodes and/or operations that a client had during the reporting year are included in the corresponding NZR episodes and operations files. ### Population People who are registered with general practitioners who participate in Nivel Zorgregistrs Eerste Lijn (NZR).
