Nineteen ACG categories contain 80.9% of patients (N=183 721). No patient was grouped in 37 ACG categories; ACG, Adjusted Clinical Groups (Code)*: Gross cost (mean/unit in euros), CV: Pearson's coefficient of variation† :outliers: percentage of patients, cut-off: T = Q₃ + 1.5 (Q₃ − Q₁), where Q₃ and Q₁ are the third and first quartiles of the distribution, respectively. Total sample: N=227 235, CV =130.0%, outliers: 6.2%.
