It concerned 292 patients with one event documented, 17 patients with two events, one patient with three events and one patient with four events. In the analyses on patient level the number of patients with one or more events with care-related harm was counted and not the number of events (n = 311 vs. n = 333). For patients with multiple events the patient is characterized by the event that led to the highest degree of preventability. The weighted percentages of patients with at least one event are presented in Table 4. In any case the total number of patients with AEs divided by total number of patients in % per EMRAM score is increasing from EMRAM-score 2 to EMRAM-score 5 on this descriptive scale. This increase is not consolidated for EMRAMscore 6 (one hospital).
