精神科病院認知症専門病棟における認知症高齢者の前向き1年間の転倒に関連するBehavioral and Psychological Symptoms of Dementiaの予測因子

抄録

　本研究は精神科病院認知症専門病棟に入院中の認知症高齢者32人の前向き1年間の転倒経験とBPSDとの関連を検討し，認知症高齢者の転倒に関するBPSDの予測因子の示唆を得ることを目的に実施した．対象者の56.3％が前向き1年間の転倒経験をもち，BPSDを所有している者は84.4％，BPSDの平均出現個数は1.9±1.3個であった．前向き1年間の転倒経験とBPSDとの関連を検討した結果，BPSDのひとつである不眠の症状を所有する認知症高齢者は前向き1年間の転倒経験と強い関連があることが示唆された．この結果から精神科病院認知症専門病棟に入院中の認知症高齢者の転倒予防対策にはBPSDの症状のひとつである不眠に対する看護介入の必要性が示唆された．

　To find predictive factors of Behavioral and Psychological Symptoms of Dementia (BPSD) for elderly dementia patients, this study examined the relation between prospective one-year falling of 32 older adults with dementia in a dementia ward of a psychiatric hospital and BPSD. In this study patients with prospective one-year falling experience were 56.3% and those with BPSD were 84.4%. The average number of BPSD was 1.9±1.3. Examination of the relation between prospective one-year falling experience and BPSD suggests that older adults with dementia suffering insomnia of BPSD show a high value of prospective one-year falling experience. The results suggest the necessity of nursing intervention for insomnia to prevent falls by elderly dementia patients in dementia wards of psychiatric hospitals.
