Illness episodes of clients of general practice participating in Nivel Care Registrations Eerste Lijn (01-01-2012-01-01-2018)

Description

This file contains diagnostic codes coded according to the International Classification of Primary Care-1 (ICPC-1) of persons registered with general practitioners participating in Nivel Care Registrations Eerste Lijn (NZR). These are diagnoses associated with illness episodes at the GP. A disease episode consists of one or more contacts with the GP for the same complaint or illness and indicates during which period the complaint or illness was present. Each record contains the diagnostic code of one disease episode, individuals may have multiple disease episodes in one year and thus occur several times in this file. 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.

A disease episode (further called &episode ') is the period between the time a patient first comes to the GP with a complaint and the moment the disease is healed or the patient has died. In chronic diseases, an episode is not closed, but people continue to count for that diagnosis over the years until the patient dies. Episodes of diseases or conditions of which the patient can heal are automatically closed if there has been no contact with the GP for a specified period of time. This shutdown period varies by type of condition and varies between 4 weeks and 1 year after the last contact. The end date of the disease episode is then established on the date of last contact plus half of the cut-off period. There is no direct relationship between the number of episodes and the number of GP contacts of a person. An episode may consist of one or more contacts with the GP over a longer period of time, while during a contact with the GP several topics may be discussed that belong to different episodes. This file contains the episodes that were present in (part of) the reporting year with clients present in NZRClient. This stock also includes a high weight, with which the results of the episodes can be increased to the entire Dutch population. For each disease episode, the start and (estimated) end date are displayed. Because chronic diseases do not close the episode, disease episodes of chronic diseases do not have an end date. Additional data have also been included per disease episode, of which it has not been examined how reliable they have been recorded. These are the dates of the first and last contact and the number of contacts with the general practitioner in the context of this disease episode, and the dates of the first and last prescriptions and the number of prescriptions of medicines for this disease or condition. If a client was enrolled in a practice with assessable disease episodes, but there are no illness episodes of the client in this file, the client has not had any disease episodes in the year under review. ### Population Disease episodes constructed by Nivel from persons enrolled in general practice participating in Nivel Zorgregistrs Eerste Lijn (NZR).
