The term Case mix refers to the type or mix of patients treated by a hospital or unit. The term is often used to describe the billing system of the hospital or unit, since the "cost per item" of healthcare is based on the casemix. ==Background== Prior to the introduction of nationally consistent Activity Based Funding (ABF) by the Commonwealth Government, Casemix based funding was the key funding model used in Australian health care services for reimbursement of the cost of patient care. In the Netherlands, the casemix system is called a "DBC" (Dutch:''Diagnosebehandelcombinatie''), and can be defined as a predefined average care package, which is applied with a fixed price when a specific diagnosis occurs.〔(DBC website )〕 Casemix is a system that measures hospital performance, aiming to reward initiatives that increase efficiency in hospitals. It also serves as an information tool that allows policy makers to understand the nature and complexity of health care delivery. Diagnosis Related Groups (DRGs) is the best-known classification system that is used in this funding model. It classifies acute inpatient episodes into a number of manageable categories based on clinical condition and resource consumption. A single acute episode of inpatient care is allocated to one DRG using coded clinical information derived from the patient’s medical record. This information is coded by the Health Information Managers in order to allocate a DRG. Each DRG is allocated a ‘weight’, which is dependent on the average cost of inputs (e.g. nursing, diagnostic services, procedures) required to achieve the appropriate patient outcome. The facility is reimbursed a predetermined amount for each patient episode. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「case mix」の詳細全文を読む スポンサード リンク
