Abstract
The target patients were those with a bedsore onset (ulcer group: 17 patients) and those with non-bedsore onset (nonulcer group:15 patients). It was slight, and the OH scale used was moderate. I assumed that the standard N-L ratio is less than 5. There were many patients in whom the N-L ratio was less than 5. The nonulcer group examined showed a change in the N-L ratio every week, and the ulcer since the hospitalization of the nonulcer and ulcer groups showed significant differences in N-L ratio. Few had an N-L ratio less than 5, and there were many with an N-L ratio greater than or equal to 5, which did not show a transient increase after the following week. An N-L ratio greater than or equal to 10 was observed in the ulcer group. In addition, I found that the N-L ratio was high on the bedsore onset day and I frequently observed patients with an N-L ratio greater than or equal to 5 one week before an ulcer developed (72.7%; 8/1 patients). Ulcer prediction factors such as the OH scale score are important in determining the way that a patient is made to lie down and in patients with difficulty in moving their body themselves in order to determine the change in the N-L ratio. I was able to confirm in particular the usefulness of the OH scale from the viewpoint of ulcer prediction.
