New directions in injury surveillance: Development of a model for continuous monitoring of direct medical costs

Information on the costs of injuries is an important additional instrument in setting priorities for injury prevention. The importance of this instrument is increasingly being recognized by health policy makers. The objective of this study was to develop a model which continuously monitors the direct medical costs of injuries in The Netherlands. This model should provide information on the direct medical costs of injuries at any time and for any selection of injury categories. It is an incidence-based model according to the ‘bottom up’ principle. Homogeneous patient groupings with respect to health care use are defined. The groupings are based on existing classifications from the literature and the experience of medical experts, and are defined by means of seven criteria: nature of care provided, body region of the injury, type of injury, severity of injury, age, complications, and sex of the patient. Several cost elements are distinguished (e.g., general practitioner help, hospital care, nursing home care). For each cost element, relevant patient groupings are determined. The new Dutch Injury Surveillance System (LIS) for injuries treated in an A&E department is an important source for incidence data. This article presents the design of the model as adopted by the Working Group on the Costs of Injuries of the European Consumer Safety Association (ECOSA).
