Data about the incidence of fractures in group homes for the elderly with dementia at 937 facilities was analysed on following aspects.
1) Per 100 residents per year, 60.0 residents had experienced a high fall, 9.7 had experienced a low-height fall, 4.3 had broken a bone during a high fall, and 0.3 had broken a bone during a low-height fall.
2) A meaningful decrease in fractures was found where average of residents' care level was ranked “over 3” in Japanese Long-term Care Insurance than ranked “over2 and under3”.
3) Comparing the rate of fracture, reinforced concrete structures with hard finished floor have a meaningfully greater rate of fall-related fractures than steel structures and reinforced concrete with shock absorbing materials under floor, and that steel reinforced concrete structures have a greater rate of fractures than do steel structures.
