About DIAMANT
The DIAMANT cohort is a population-based, dynamic, prospective cohort of persons with diabetes. It contains real-world data (RWD) from general practitioners (GP), including diagnoses, symptoms, examinations, communication to/from specialists and medication. Diabetes is defined as a recorded diabetes diagnosis or a prescription of drugs used in diabetes.
The cohort is part of the national infrastructure of “Stichting Informatievoorziening voor Zorg en Onderzoek” (STIZON) and is linked to other data sources.
Available data
Currently, the cohort enables access to information of 89,883 patients in 2004 to 344,914 in 2020 (6% T1D, 84% T2D and 10% unclassified type of diabetes), with 193,931 participants still registered as being present in the GP practice (active) in 2020. The frequency of follow-up of persons with diabetes is practice dependent. The Dutch guidelines advise 2-4 contacts per year with a more extensive yearly check-up. The DIAMANT cohort is updated several times a year. Anonymised data from the DIAMANT cohort are available for researchers.
Facts and figures
- The DIAMANT cohort was established in 2019 and has no fixed time window for in- and exclusion. Effectively, the cohort enables access to information of ~90,000 patients in 2004 to almost 350,000 in 2020 (6% T1D, 84% T2D and for 10% type of diabetes was not recorded), with almost 200,000 participants still registered as being present in 2020.
- Frequency of follow-up of persons with diabetes is GP practice dependent. The Dutch guidelines advise two to four contacts per year with a more extensive yearly check-up. The DIAMANT cohort is updated several times a year.
- Due to the mandatory registration in a GP practice of the Dutch health care system, selection bias in the cohort is minimal.
- The main aim of the DIAMANT cohort is to gain real-life insights into the treatment and outcomes among people with diabetes in daily general practice in order to prevent diabetes and its complications.
- De-identified data from the DIAMANT cohort are available for researchers.
