(1)情報処理方法の概要
図4を参照しながら、情報処理方法について説明する。 3. Information Processing Method (1) Outline of Information Processing Method The information processing method will be described with reference to FIG.
(a)環境指標
環境指標については、気温+湿度、気圧、照度ごとに算出される不快度を指標とすることができる。まず、気温+湿度については公知の快適範囲を示すグラフを利用し、快適範囲にあるかどうかにより、不快であるかどうかを判断する。 (2) Example of indexing process (a) Environmental index For the environmental index, the degree of discomfort calculated for each temperature + humidity, atmospheric pressure, and illuminance can be used as an index. First, regarding temperature + humidity, a graph indicating a known comfort range is used to determine whether it is uncomfortable depending on whether it is within the comfort range.
心拍数は1分間の心拍数をP、平均の心拍数をP0として生体指標P’は以下の計算式で求める。
(a)予測ロジック
予測のロジックをPとした場合、以下の式に基づき行列計算を行いPの算出を行うことができる。
BPSDの発生時期の予測は、いくつかの基準点を元に時間帯の関連性を導出することができる。その指標として、以下の時刻を基準点として候補に挙げる。
1)0時(日付変更点)
2)日出(日没)
3)起床
4)食事 (B) Prediction of the occurrence time of BPSD The prediction of the occurrence time of BPSD can derive the relevance of the time zone based on several reference points. As the index, the following times are listed as candidates as reference points.
1) 0:00 (date change point)
2) Hiji (sunset)
3) Waking up 4) Meals
BPSDの発生において、周囲の環境が及ぼす影響は大きいため、BPSD発生時の環境要因、特に気温、湿度、気圧、照度、臭い、騒音について分析を行うことができる。気温、湿度については温湿度の関連に対しての快適性指標グラフを元に、快適性の度合いを診断し、それを指標とすることができる。気圧、照度、臭い、騒音については、それぞれ単一指標としてBPSDの発生との関連性を分析し、それぞれ回帰分析を行うことにより、各指標のBPSDに対する影響と度合を算出することができる。 (C) Prediction from the environmental factors of BPSD Since the influence of the surrounding environment on the occurrence of BPSD is large, it is possible to analyze the environmental factors at the time of BPSD occurrence, especially temperature, humidity, atmospheric pressure, illuminance, smell, and noise. it can. As for the temperature and humidity, the degree of comfort can be diagnosed based on the comfort index graph for the relationship between temperature and humidity and can be used as an index. For atmospheric pressure, illuminance, odor, and noise, the influence and degree of each index on BPSD can be calculated by analyzing the relationship with the occurrence of BPSD as a single index and performing regression analysis.
自然言語解析により、BPSDを解析することもできる。質問や問い合わせに含まれる品詞を自然言語処理にて特定した後、仮説を生成し、次にその仮説を支持または証拠を探すやり方である。証拠加重スコアの統計モデル手法に従って、BPSDの発症状態をベースにして、対応方法を割り当てる。 (D) Prediction from natural language analysis BPSD can also be analyzed by natural language analysis. This is a method in which a part of speech included in a question or inquiry is identified by natural language processing, a hypothesis is generated, and then the hypothesis is supported or searched for evidence. A response method is assigned based on the onset status of BPSD according to the statistical model method of the evidence weight score.
図10に示すように、認知症患者の行動から、BPSDの相関がわかる。これによって、認知症患者の行動からBPSDの発症を予測することができる。 (E) Prediction from behavior As shown in FIG. 10, the correlation of BPSD is known from the behavior of a dementia patient. Thereby, the onset of BPSD can be predicted from the behavior of the dementia patient.
BPSDの症状に基づき、関数20aまたは分類器20bに基づき、対処方法を生成することができる。また、BPSDの症状と、対応方法との対応表20dに基づき、BPSDの対処方法を選択してもよい。図12に示すような対応表20dを記憶部20に記憶させておいてもよい。 (4) Coping method Based on the BPSD symptoms, a coping method can be generated based on the function 20a or the classifier 20b. Further, a BPSD coping method may be selected based on the correspondence table 20d between BPSD symptoms and coping methods. A correspondence table 20 d as shown in FIG. 12 may be stored in the
(a)発生の評価
BPSD の発症についての検証は、BPSD問題行動の評価尺度(TBS:Troublesome Behavior Scale)により行うことができる。TBS は高齢者認知症患の破壊行動や負担を記述する。 (5) Verification (a) Evaluation of Occurrence Verification of the onset of BPSD can be performed by a BPSD problem behavior evaluation scale (TBS: Troublesome Behavior Scale). TBS describes the destructive behavior and burden of elderly people with dementia.
(b)対処方法の評価
BPSD対処の評価を通して、ケア方法の導出が、どの程度の評価を獲得したかによってその信頼度を評価する。介護現場から収集される大量のデータにアナリティクスを実行し、洞察を収集してインスピレーションに変換することで、適切なケア方法を導出できるようにすることができる。BPSDの対処方法の評価において、認知症患者がBPSDが発症したかどうかをデータ取得部40が取得したデータまたは入力部52により入力されたデータに基づき、処理部30において対処方法の是非を検証してもよい。この検証結果に基づき、学習部30dが、対処方法導出部30dの導出アルゴリズムを学習させ、導出アルゴリズムの更新をすることができる。この対処方法導出部30dの導出アルゴリズムの学習のさせ方は、予測部30dの予測アルゴリズムの学習と同様に行うことができる。 Specifically, the
(B) Evaluation of coping method Through the evaluation of coping with BPSD, the degree of reliability is evaluated according to how much evaluation the derivation of the care method has acquired. By running analytics on the massive amount of data collected from care sites, collecting insights and converting them into inspiration can help derive appropriate care methods. In the evaluation of the BPSD coping method, whether the dementia patient has developed BPSD or not is verified by the
BPSDの発症または発症の時期を予測して、早期の対処により、BPSDの発症を未然に防ぎ、BPSDの発生自体を大幅に減らすことを可能にする。BPSDを事前に予測することができるため、介護者の負担を減らすことができる。 3. Effects The occurrence of BPSD or the timing of the onset is predicted, and early treatment can prevent the onset of BPSD in advance and greatly reduce the occurrence of BPSD itself. Since BPSD can be predicted in advance, the burden on the caregiver can be reduced.
