有料老人ホームの冬季室内温熱環境が入居者の要介護度の重度化に及ぼす影響: 介護施設の室内温熱環境と入居者の要介護状態に関する実態調査

摘要

Fifteen nursing home facilities were classified into two temperature groups (warm and cold) and two hurnidity groups (moist and dry) according to measured room temperature and relative humidity, respectively. Cox proportional hazards regression analysis was used to assess the effect of indoor thermal environment on the condition of residents, characterised by the need for care. Two questions were evaluated: "Did the needed care level deteriorate (i.e.， intensify)?" and "If so, how long did it take for care level to deteriorate?" The results showed that the cold group and the dry group had higher risks of deterioration of care level. Furthermore, residents in facilities that were both warm and moist had the lowest risk. This result suggests that both temperature and humidity are important in preventing the need for care.%本報では、2015年冬季に実施した実測調査と2015， 2016年の2 回にかけて実施した質問紙調査結果を用いて介護施設の室内温熱環 境と入居者の要介護度重度化の関連について検討した。その結果、 以下の知見が得られた。
