Design, Setting, And Participants: Observational cohort study with patient enrollment between July 1, 2012, and December 31, 2017, and a follow-up to March 19, 2020.

Assessing volume and variation of low-value care practices in the Netherlands.

Background: There have been contributions to quantify the volume of low-value care practices in the USA, Canada and Australia but we have no knowledge about the volume in Europe. The purpose of this study was to assess the volume and variation of Dutch low-value care practices.

Methods: We conducted a cross-sectional study with data of a Dutch healthcare insurance company from general practioners (GP's) and hospitals in the Netherlands from 2016.
