     Background

     "Unit care", in which a small number of residents live together, has been one of the effective methods to the practice of individual care in elderly facilities. The unit care type facilities were adopted not only in the nursing home but also in other elderly facilities and welfare facilities. However, the unit type is said to have the following problems. The first is that the staff spends a lot of time alone assisting in the unit, and the second is that it is difficult to educate staff.

     So, in this survey, from the viewpoint of planning of scale in care group, we are considered improvement of working environment of staff.

     Objective

     The purpose of this study is to clarify the effects of the differences in the scale of nursing care units on the work system and nursing care contents. The subjects of the survey were: 7-8 person unit, 10-person units (2 facilities A, B), 12-person unit and 13-person unit.

     Research Method

     The survey methods were interview survey, behavior observation survey and activity amount survey of staffs. The period of behavior observation survey was 24 hours × 3 days, and the target unit were 2 units of each facility.

     Conclusions

     (1) Shift of care staffs during the daytime: The 7-8 person unit and 10-person unit B had a two-person system for early and late shift. The 10-person unit A had a three-person system for early, day, and late shift. The 12-person unit and the 13-person unit had a four-person system for early, day shift, and two late shift staffs.

     (2) Percentage of the number of staffs stayed in the unit: In the 7-8 person unit, the ratio of no staff in the unit was 8.4% (75.6 minutes). On the other hand, in the 12-person unit, the ratio of two or more staffs in the Unit was 64.2% and that in the 13-person unit was 73.3%.

     (3) Percentage of time when there was no staff in LDK: 7-8 person unit is 51% (464.6 minutes), 10-person unit A was 37% (333 minutes) and 10-person unit B was 36% (324 minutes). 12-person unit 37% (333 minutes) and 13-person unit was 28% (243 minutes). The difference between the 7-8 person unit and the 13-person unit was as large as 23%.

     (4) Characteristics of individual assistance: Regarding bathing assistance, the 13-person unit also provided assistance at night, but the 10-person unit A and the 10-person unit B provided assistance in the morning.

     As for dietary assistance, breakfast was provided at all facilities in accordance with the life rhythm of individual residents. For lunch and dinner, the 7-8 person unit, 10 person unit A, 10 person unit B and 12 person unit had a uniform meal time, but the 13 person unit had a long meal time and individual care was possible.

     Regarding excretion assistance, in the 12-person unit and the 13-person unit, the difference between the regular excretion assistance time and that in other time zones was small, and excretion assistance was frequently provided.

     (5) Information transmission such as records and business conversation: In the 7-8 person unit, there were few conversations during work, and information was communicated by meeting and recording. In the 12-person unit, in addition to records, there were long meeting time and business conversations during work, and information was shared among staffs.

     Background

     In Japan, which is becoming a high-mortality society in addition to a super-aging society, the establishment of a suitable residence for older people to spend their last days is an urgent concern. In a home type hospice, which is a residence wherein home care services are provided and covered under nursing insurance, 5-6 individuals live together. Although home type hospices are expected to play an important role in the future as one of the residential options for patients to spend the terminal stage of their life, no study has assessed the actual living conditions and physical characteristics of home type hospices.

     Reserch Objectives

     By understanding the actual environment, such as resident attributes and nursing care provision system, this study aimed to clarify the characteristics of home hospices, which primarily utilize existing residences.

     Research Methods

     The target residences were 28 business establishments and 37 buildings in Japan, which were certified by the Japan Home Hospice Association. Surveys were conducted through interviews with the administrator of each business establishment.

     Conclusion

     1. There are age limitations for moving elderly people to facilities and residences providing home care services. However, home type hospices accept residents regardless of their age. While the majority of the residents are aged >80 years, there are some residents aged <60 years. 2. If we assess the reason and duration of occupancy of such facilities on the basis of disease type, cancer-centric home type hospices mostly accept patients in need of medical care, and most residents remain in the facility for a short duration, usually <1 year. These facilities provide hospice care for patients in the terminal stage of their life. Dementia-centric home hospices support patients with severe dementia. It is believed that these houses complement the insufficiency of facilities in different regions and the variety in the levels of care that is provided. Complex home hospices mostly accept patients in need of medical care and who could not live at their own residence. Thus, home hospices may accept residents regardless of the patient's age and disease type, including older people and those with malignant diseases, respectively. In addition, these facilities function as a safety net for patients with severe conditions, who are difficult to deal with in the existing system . 3. Apart from home type hospices, there were 25 business establishments that were serving as home-visit nursing agencies, accounting for approximately 90% of the surveyed facilities. Cooperation between resident staff, which is responsible for providing daily living support, and home-visit nursing agencies is necessary to provide continuous support before moving patients. Therefore, in many cases, home-visit nursing was provided in the business establishments. 4. Renovation of buildings could be classified into four types, namely "improvement in building performance, " "improvement in accessibility, " "space expansion, " and "barrier-free design." Increase in the number of bathrooms/washrooms and toilets as well as renovation to accommodate wheelchairs were the most common. To utilize existing buildings as home type hospices, emphasis should be particularly given to the barrier-free design of plumbing fixtures. 5. Introduction through acquaintances was the most common method of property selection. It tended to reflect a higher level of connection and recognition with the local residents. This must be because of the owner's connection with the region, which is shared with the new property owner.

     This study aims to quantify the structural damages, evacuation situation, and utility interruptions caused to facilities for the elderly in the 2016 Kumamoto earthquake. We gathered data by administering a questionnaire to all facilities for the elderly in Kumamoto and Oita prefectures, and a series of interviews administered at 17 facilities in the Kumamoto prefecture. The results are as follows:
     1) The foreshock caused structural damages in 56.2% and 16.1% of facilities in the Kumamoto and Oita prefectures, respectively. Further, the main earthquake caused structural damages in 69.2% and 21.4% facilities in the Kumamoto and Oita prefectures, respectively. The interior and exterior walls and ceilings were found to be cracked, and some furniture were damaged, while the interior of one of the facilities was severely damaged by flooding because of a sprinkler malfunction. After the foreshock, in most facilities, the furniture was damaged because it was not fixed to the walls. To ensure less damage after the foreshock, most facilities took precautions such as putting tall furniture on the floor and moving the residents' beds to a safe space.
     2) According to the interview survey, most of three facilities to which evacuees temporarily fled from outside the facilities, and they returned to the facilities in the following morning after staying a night in vehicles. Evacuation to other facilities was made at only two facilities of GH. At four facilities, most of which were nursing homes, residents gathered in a space. At unit-type nursing homes, residents gathered in a dining room and a hallway within a unit, and at old type nursing homes, residents gathered in a functional recovery training room and an elevator hall. The number of residents per room changed at only one unit type nursing home.
     3) According to the questionnaire survey, electricity was lost in 21.4% of the facilities, water supply was lost in 25.3% of the facilities, gas outage was observed in 55.6% of the facilities, with 12.1% of propane gas outage, and 6.3% of facilities suffered from sewage drainage stops. According to the interview survey, no facilities experienced a serious shortage of food because relief supplies became available and procurement became possible after a few days of subsistence with their food stock.
     4) About a quarter of the facilities (29.5%) accepted evacuees who needed care, and 17.6% accepted general evacuees by the questionnaire survey. The interview survey found that there were many cases where local residents evacuated their homes because they felt uneasy about the aftershocks following the foreshock, and no facilities clearly differentiated required assistances from general evacuees when they accepted evacuees, and the facilities used their community regional common space, entrance hall, and annexed day service floor as an evacuation space.

Out of these, (1) cooperation in provision of medicine and care and (2) prevention, health, life support, and various preparations of counseling services are important problems of the future. Especially, the latter services concerning prevention and health, and life support, are required to develop in each region. However, this service has been established in the insurance system. Omuta city started the Community Center Project in 2006, and this project has worked on the prevention of a long-term care state and health class in the core of community centers. It is located throughout the city: the number of community centers was 36 and 40 facilities in 2010 and 2014, respectively. This study aims to clarify the time series change of facility management and the factors that activate it. The investigation period was between 2010 and 2014, five and nine years since the project started. 2. Research Method The objects of this study were all the community centers opened in Omuta city as of April 2014. The methods used included a questionnaire, interview, and location survey. The questionnaire comprised facility management and actual performance for each facility. The recovery rate of the questionnaires was 100% in 2010 and 92.5% (actual performance rate was 87.5%) in 2014. Interviews were conducted on 10 facilities. The locational survey rate was 40/40 and the analyses of floor plans were 39/40. 3. Discussion 1) The facility of "Opening at amount of time hours" in 2010 and 2014 was more than 80%. The facility operated from six to nine hours. The percentage for opening hours was about 60%. 2) A steering group in action decreased proprietary activities by corporations and increased group activities by citizens. 3) In 2014, the average monthly number of openings per facility was 20 counts; the average monthly number of participants per facility was 163 people. A comparison of 2010 and 2014 show a significant difference of 1% for both indexes. 4) In the case study, community centers served the function of providing consultation services from social welfare workers and residents, finding problems, and noticing changes of local residents. It also acted as an intermediary to specialized agencies and coordinated with various organizations. 5) Factors influencing the revitalization of community centers from statistical investigation were as follows: (a) Having staff on duty at all times in the community center, and always being open in the daytime; (b) Conducting original activities for children and commissioned projects from local governments; (c) Advertising facilities in the area to create public relations papers; (d) Developing a relationship between human resources, such as regarding volunteer; and (e) Participating in neighborhood community associations and community activities.

    The aims of this paper is acquiring planned knowledge through present and actual condition grasp of "community base small multi care facilities" which is a place to support the aged people requiring care of being home that was newly appeared by the public-nursing-care-insurance revision in April, 2006. Investigation is based on the actual condition grasp investigation by the questionnaire in a nationwide scale. The management of institutions and the actual condition of a construction outline which have been just institutionalized became clear. Since there are many examples using especially the existing building, it is necessary to grasp from now on in nearby details, such as the method of practical use of the existing building, and a subject in that case. Moreover, since the state of the space composition of "visiting" and "night staying" portion, the kind of compound function, etc. are also the points which lead to the state of the plan of the facilities directly, analysis is advanced and pursuit of a planned subject and pursuit of planned knowledge are needed.

    本論では、特別養護老人ホームとグループホームの2種類を取り上げ、両者における錯誤行動の違いを検証することによって、環境が認知症高齢者の行動におよぼす影響を考察する。施設の介護スタッフに日常見られる錯誤行動の事例を聞くフォーカスインタビュー調査を行い、その結果を8つのカテゴリーに分類した。分析の結果、8つのカテゴリーの錯誤行動には、2)建物内の探索・迷込のように特別養護老人ホームに多く見られる傾向のものと、逆に1)外出・出入、6)作業のようにグループホームに多く見られる傾向のあるものとがあることが示唆された。また、3)排泄・不潔行動、5)物品関連などは、有意に多い施設がみられるが、特別養護老人ホームとグループホームで傾向が分かれないカテゴリーと考えられる。カテゴリーごとに事例の特徴を検討し考察した結果、特別養護老人ホームとグループホームの間の物理的環境の差異が施設による報告の多寡の背景にある可能性がいくつか指摘された。

    This study clarifies the effects of downsizing of care units on individual care. To make it clear, the behavioral tracking surveys for staff and residents were carried out at an existing nursing home. The results are as follows: 1) The staff members go to other units less frequently, and stay longer at their own units. 2) The amount of physical care given to residents maintains, and that of communication increases. Staff members give care residents twice as long as before. 3) Staff members shared information at a meeting room where all of them attended, but now they do by communicating each other within their own units.

    The purpose of this study is to clarify the circumstances in which the residents' postures are changed in a nursing home. The residents' behavior tracking survey and the interviews with the staff were performed for this study. The results are as follows. 1)As the body functional capacity declines, the ratio of staying in a common space decreases. Some with akathisia or with dysphagia were observed bedridden for the whole day. 2)As the body functional capacity declines, the variation and the number of the residents' postures decreases. 3)Among the postures observed of those who are unable to transfer or with akathisia and dysphagia. "sitting on a wheelchair" holds 100% of the data in the common spaces. And some were observed staying seated for quite a long time in one day

    The purpose of this paper is to summarize the current status of improving the residential settings for the elderly and to discuss the future issues in the relating field. This study focuses on the importance of minimizing relocation shock that the elderly experience in the process of moving to a new facility and of the physical environment which facilitates adaptation to a new environment. Personalizing residents' rooms and planning common spaces which afford the various life patterns - this is the first endeavor seen in the improvement process at nursing homes. Spatial composi- tion in the smaller setting such as a GH is also introduced as another key factor in the process at the large facility. This paper also introduces "Group House AMAGASAKI" as the most leading case.

    インカムの導入がリーダー起点とした会話から多極型の会話に構造が変化すること，他の職員との連携，利用者や職員を待たせる時間の減少の有効性を実証した．こうした効果は，特にフロア面積の広いデイケア施設で認められ，歩数が30％弱減少する事例もあった．一方で，歩数の減少が認められない個室ユニット型の特養もあったが，アンケート調査の結果からは，介護職員は業務時の移動距離の減少が実感されていた．これは，インカムの導入による無駄な動きの減少が実感された結果と考えられる．心拍数の変動から介護中のストレスを算出した結果，職員間の会話などでストレスが高く，インカムなどによるコミュニケーションの改善可能性を把握した．

    高齢者向け住宅における互助活動を活性化していくためには、住民相互の関係性を醸成していく「出来事」や「場所」が必要となる。本年度は、高齢化が進み高齢者向け住宅と同じ問題を抱える公営住宅におけるコミュニティ活動の実態調査を実施した。本調査対象施設の特徴は、住民の自治機能だけに依存するのではなく、行政、地域包括支援センター、介護事業所といった地域機能が連携しコミュニティ活動を推進している点にある。具体的な活動は、月1回のサークル活動、独居高齢者に対する見守り活動、認知症に対する研修やまちづくりイベント等である。調査方法は、関係者に対するヒアリング調査や現地における記録調査であり、これらの活動を詳細に記録することを目的とする。その結果、１）コミュニティ活動の推進は、中立的な立場である行政からの働きかけと補助金等の資金援助が重要であり、これらの支援により初期活動が円滑に行われていた。２）地域包括支援センターや介護事業所は健康体操や各種のレクリエーション活動に対する経験が豊富であり継続的な会を維持していくことに大きな貢献を果たしていた。３）各種のボランティアサークルを招くことにより経済的に多様な活動を取り込むことができていた。４）見守り活動を行うことにより住民相互の関心と理解が深まっていた。５）高齢者の自治活動には継続的な外部からの支援が必要である。ということが明らかとなった。本研究の結果から住民によるコミュニティ活動は引きこもりの防止や、住民同士の理解にはつながっていたが、助け合い活動までは進展していなかった。会の継続についても外部からの支援による部分が多く、完全に自主的に運営してくことは困難であることが分かった。また、本研究ではこれらの活動を詳細に表現し、第三者にも理解しやすい資料の作成を行った。
