Long-Term Active and Passive Horticultural Therapy Intervention for Elderly Patients with Moderate Dementia and AI Analysis of Medical Records and Care Documents

Background: Previous studies have shown that Hand Care Treatment, a form of passive horticultural therapy, is effective in preventing dementia and MCI and reducing the rate of progression. Due to the Covid-19 pandemic, various activity restrictions were implemented in Japan from March 2020, and the number of elderly people without care and rehabilitation will the number of elderly people without care and rehabilitation has been increasing. Purpose: Progression of cognitive, physical, and mental disability was examined for long-term horticultural therapy study subjects by level of care required. Methods: One subject who had been diagnosed with dementia and was residing in an elderly care facility and consented to a long-term study was selected. In addition to assessments using various evaluation forms, data recorded from time to time, including changes in care plans, were analyzed using text mining methods. Results: This subject tended to progress slowly from 1 to 2 care needs, but progressed from 3 to 5 care needs over a 2-year period. The results of the assessment chart test showed that cognitive impairment and IADL decreased with each increase in the level of care required, but DBD remained the same at the time of admission, even at 5 years of care required. A comparison of HCT and aroma intervention with and without aroma intervention during the nursing care level 1 showed that the improvement in physical, mental, and cognitive function was expected to be higher at the time of intervention. Text-mining inspections have revealed that during the period of nursing care level 1 - 5, active horticultural therapy techniques, and passive horticultural therapy techniques such as HCT and brain rejuvenation aromatherapy were found to betweenness centrality with each
