In orthopedic surgery, there are many patients who undergo surgery for bone fractures, and the most common fracture site is the femur, followed by forearm fractures.
Femoral fractures are common among elderly people, and many of them are transferred to rehabilitation hospitals to continue treatment once their physical condition stabilizes after surgery.
In addition to fractures, it is characterized by many spinal diseases such as intervertebral disc herniation and spinal canal stenosis.
For both diseases, the length of hospital stay is shorter than the national average, and early discharge is possible.

The number and incidence of disseminated intravascular coagulation, sepsis, mycosis, and surgical/procedural complications were tabulated.
Data are tabulated according to whether the DPC disease name and the reason for hospitalization are the same or different.

◇Explanation
For sepsis, 34 cases were the same as the cause of hospitalization, and 24 cases were different.
There are various injuries and diseases that cause hospitalization, but urinary tract infections are the most common.
As complications such as operation, treatment, most are the same as hospitalization opportunity.
Injuries and diseases include artificial blood vessel infection, post-pacemaker implantation infection, and surgical wound dissection.
