  1. Notes: The included diagnosis code is always related to the coded main diagnosis. The exclusion restriction for the diagnosis code is related to the secondary diagnosis. If diagnosis code and procedure codes are specified, a patient is only included in the sample if in each category at least one code exists. Diagnosis codes are based on the international statistical classification of diseases (ICD-10-GM). Procedure codes are based on the German classification system for procedures.
  2. PNEU - pneumonia; APP - appendectomy; CHOL - cholecystectomy; HAP - hip arthroplasty; KAP - knee arthroplasty; HIP - hip fracture; AAA - intact abdominal aortic aneurysm; CABG - coronary artery bypass surgery.
