| Outline of Final Research Achievements |
We investigated occurrences of bone fractures and traumatic head injuries during hospitalization and the risk factors for in-hospital mortality in acute care hospitals.
The incidence rate of fractures during hospitalization was 0.32%, The fracture sites of the vertebral bones,femurs,and ribs accounted for more than 70% of the total incidents.The in-hospitalW mortality rate was 9.5%, and the in-hospital mortality risk factors revealed that cases of traumatic head injury, femoral fracture, humeral fracture, and independent walking upon admission, in conjunction with having a BMI <18.5 and being male, increased in-hospital mortality risk.The incidence rate of traumatic head injury was 0.046% and in-hospital mortality was 17.9%. surgery for traumatic head injury, psychotropic drugs, having a low BMI, and being male were factors increasing the risk of mortality.

| Academic Significance and Societal Importance of the Research Achievements |
世界的に高齢化が進んでいるなかで、転倒転落の発生防止は日本のみならず世界的な課題となっている。なかでも、骨折や外傷性頭部損傷を引き起こすような転倒転落の発生防止は患者のQOL,予後、医療経済的な観点からも喫緊の課題である。また、入院中の病的骨折以外の骨折および外傷性頭部損傷の原因の多くは転倒・転落等のアクシデントに起因するものと推測される。本研究結果は入院中の転倒・転落で骨折または外傷性頭部損傷が発生した際に重篤な転期（在院死亡）となるリスクの高い患者の識別に応用できる可能性がある。
