[Total knee and hip arthroplasty within 2 days : The Danish Fast-Track Model].

BACKGROUND: Patients in Denmark undergoing total knee or hip replacement are routinely discharged within 2 days of surgery. A critical examination of traditional treatment methods, combined with focused research, has during the last 20 years increasingly optimized the treatment course in such a way that it has become possible to radically reduce the length of stay (LOS). BASICS OF THE FAST-TRACK MODEL: The most important elements of this Fast-Track model are described. The patient motivation and transfer of partial responsibility to the patient through intensive information, optimized operation techniques, as well as modern multi-modal pain therapy with early mobilization are key issues. The relatively small and homogenous health care system of Denmark offers good research conditions and the possibility of a fast implementation of the latest results, as well as a lump-sum based re-imbursement system without minimum stay-both factors have been favorable for the development of the Fast-Track model.
