As a result of review of criteria on "severity and degree of medical/nursing needs" for hospitalization basic charges at the revision of the medical fee in April 2014, issues such as admittance of patients with high nursing needs while maintaining higher rate of bed occupancy are noted. In order to address the issue, I have extracted the factors that predict a patient's state of post-operative care requirements using the DPC information and patient classification method II. As a result, a patients group with complex surgeries under general anesthesia and a group diagnosed to require postoperative management are extracted. The result also indicated concentrated screening of "MDC06: Digestive System, Hepatobiliary, and Pancreas disease" is important in efficient care unit operations.
