Description
Summary:The length of stay and the effectiveness of medical treatment are analyzed using data from patients hospitalized for hip fractures in Japan. The influence of the Revision of the Medical Service Fee Schedule in April 2002 is evaluated, and factors which may affect the length of stay and the effectiveness of treatment (walking ability upon leaving the hospital) are also analyzed. The length of stay is analyzed by the discrete-type proportional hazard model, and the effectiveness of treatment is analyzed by the ordered probit models.
