DRGs: 1st step = patient classification / grouping medical and management decision variables patient variables gender, age, main diagnosis, other diagnoses, severity mix and intensity of procedures, technologies and human resource use Group of patients with homogenous resource consumption = DRG Hospital Financing in Germany: The G-DRG System
Price setting under DRGs (I) medical and management decision variables patient variables gender, age, main diagnosis, other diagnoses, severity mix and intensity of procedures, technologies and human resource use DRG reimbursement X = base rate cost weight Hospital Financing in Germany: The G-DRG System
Price setting under DRGs (II) determinants of hospital costs structural variables on hospital/ regional/ national level medical and management decision variables patient variables gender, age, main diagnosis, other diagnoses, severity mix and intensity of procedures, technologies and human resource use e.g. size, teaching status; urbanity; wage level DRG reimbursement X = base rate cost weight + adjustment factors Hospital Financing in Germany: The G-DRG System
Design options for DRG systems Conflictingaimsof DRG systems Practicability (small number of groups) Homogenous groups (groups of cases with similar costs) France: ~2,300 Germany: 1,200 Estonia: ~500 Examples: Hospital Financing in Germany: The G-DRG System

1) Phase of preparation: How to construct a system? Patient classification system Price setting Data collection Reimbursement rate • Diagnoses • Procedures • Severity • Clinical data • Cost data • Sample size • Average prices • Cost weights • Outliers • High cost cases Hospital Financing in Germany: The G-DRG System
1) Phase of preparation: Patient Classification Patient classification system • Diagnoses • Procedures • Severity Hospital Financing in Germany: The G-DRG System
1) Phase of preparation: Data collection Data collection • InEK • Development of case fee catalogue annually • checking data content • Clinical data • Cost data • Sample size • DIMDI • Development and update of classification base (ICD -10 GM and OPS codes) Checked and anonymised data • Data Centre • Collecting datasets • Checking case and cost data technically • Anonymising data Case-related performance and hospital-specific structural data from every hospital (§21 KHEntgG) until March 31 Additionally case-related cost data from a sample of hospitals until March 31 Hospitals • Sickness funds • Checking data via their medical review board • Paying hospital Case data for reimbursement (§ 301 SGB V) • Federal Statistical Office • Publication of data Until July 1 Hospital Financing in Germany: The G-DRG System
1) Phase of preparation: Price setting mechanism Price setting • Calculation of cost weights: based on average costs of cases • Data sample: Cost weight of each DRG = Average costs of DRG inliers / Reference Value • Average prices • Cost weights Hospital Financing in Germany: The G-DRG System
