Notes: Join function: Logit. ^a This parameter is set to 0 because it is redundant. CI: confidence interval, PSG: patient safety grade, NER: number of events reported. * represents the dimensions and items with statistical significance in surgical departments. PSG: Patient safety grade. NER: Number of events reported.
