4 Measures to prevent patient safety incidents: Measures are taken in the practice to prevent critical incidents (1). In the practice, responsibility for the implementation of these measures (0.5) and the period over which the implementation is to take place (0.5) are also fixed. In addition, the practice learns from incidents that have occurred in other practices and takes measures to avoid critical incidents accordingly (1)0, 0.5

  • The result of the primary analysis at 12 months is displayed at the top (intention to treat). Indicator scores were calculated by dividing the sum of fulfilled criteria by the total number of criteria per indicator, resulting in a score between 0 and 1; ‘0’ denotes ‘no criterion achieved’ and 1 ‘all criteria achieved’. Mean and SD are presented. The description of criteria, with scores displayed depending on the number of fulfilled criteria, is shown further down (Note: Results of complete cases are displayed). Criteria 2–6 are self-reported, criterion 1 is assessed by chart review.
