Objective: To reduce the occurrence of bedsores in a nursing home health care facility, the characteristics of bedsore generation were examined, based on the OH scale (Ashina version) considering assessment of the bedsore risk and the recurrence rate and occurrence site.
Methods: We selected 220 patients suffering from bedsores among 1.330 subjects who entered the facility during the 4 years and 4 months from September 2012 through December 2016. The degree of severity and score on the scale, recurrence rate, and site of occurrence were retrospectively investigated.
Results: The risk severity was highest in the middle risk group. The recurrence rate was 49% in relapse. The buttocks were the most frequent site of occurrence.
Discussion: Although there were differences in physical ability among the subjects in the middle risk group, it is thought that the reasons for the highest number of occurrences were that a unified treatment was given, although there were considerable differences in awareness and efforts toward prevention of bedsore occurrence, and that there was a change in the risk of bedsore occurrence due to changes in the subjects’ physical condition. Regarding the recurrence rate, it is thought that since, after bedsores were completely healed, awareness of prevention of recurrence was weakened, and treatment reverted to that before the occurrence of the bedsores, the number of relapses increased. In regard to site of occurrence, since the buttocks cover a relatively large area, pressure is liable to be applied both in the sitting position and when lying down, particularly in the sitting position. It is considered that the high frequency of occurrence was increased by the long time spent in the sitting position.
