Palliative care in small-scale living facilities: a scoping review
BMC Geriatrics volume 24, Article number: 700 (2024)
Abstract
Background
Innovative small-scale facilities for dementia focus on providing quality of life and maintaining the functional abilities of residents while offering residents a home for life. To fulfill the home-for-life principle, palliative care approaches are necessary to maintain quality of life in these facilities. Few studies have reported on how palliative care is provided to residents in small-scale facilities. The aim of our review is to determine the extent to which palliative care approaches are reported in small-scale facilities.
Methods
A scoping review of the literature using recommended methods from the Joanna Briggs Institute. Four databases, CINAHL, PubMed, PsycINFO, and Web of Science, were searched for studies published from 1995 to 2023. One reviewer completed the title, abstract and full-text screening and data extraction; two additional team members piloted the screening and extraction process and met with the main reviewer to make decisions about article inclusion and ensure consistency and accuracy in the review process. The extracted data was open-coded and analyzed using thematic analysis. The data was then synthesized into themes using palliative care domains for dementia.
Results
Of the 800 articles obtained in the search, only ten met the inclusion criteria: six from Japan, two from the Netherlands, and one each from Austria and the United States. In most small-scale facilities, palliative care is important, with facilities prioritizing family involvement and person-centred care, minimizing resident discomfort and enhancing residents’ remaining abilities until the end of life. The included studies did not discuss palliative care policies or professional staff training in depth.
Conclusions
This study provides an overview of the literature on palliative care in small-scale facilities for individuals with dementia. Most facilities focus on residents’ wishes at the end of life to enhance comfort and provide a home-like environment. However, more research is needed to further understand the quality of palliative care approaches in these homes.
Background
Innovative small-scale care environments are designed to meet the complex needs of residents with dementia by maintaining their functional ability and quality of life in a person-centred way while maintaining a true home-like setting [1,2,3]. Small-scale facilities provide physical and psychosocial care for older adults or individuals who are no longer able to live independently. Small-scale facilities differ from long-term care facilities because they have a smaller number of residents (six to fifteen on average). These facilities provide a community environment and person-centred care while stimulating resident autonomy by promoting active participation in social activities, household chores, and decision-making surrounding daily schedules [1,2,3,4,5]. To create a home-like environment, these facilities include home-like kitchens, living rooms, and private bedrooms while also allowing residents to bring pets and furniture from home [1, 3, 6]. Staff in these environments are often responsible for multiple additional tasks, including cooking and cleaning [3]. Small-scale facilities are also “a home for life”, meaning that residents can stay and live a purposeful life within these homes until their death [3, 7].
There are multiple types of small-scale facilities internationally [3]. These include Group Living/Homes (Japan/Sweden), Small-scale Living Facilities (Netherlands/Belgium), Green Care Farms (Netherlands), Residential Groups (Germany), Cantou (France), Care Housing (Scotland), Domuses (United Kingdom), Woodside Place (Canada/United States), and Green Houses (United States) [3, 8]. Recently, research has focused on the outcomes of living in small-scale homes compared to traditional long-term care; however, few studies have reported on palliative care approaches in these homes [3,4,5, 9]. With these studies reporting that residents in small-scale homes have increased social and physical engagement and functioning compared to residents in long-term care and with these facilities growing in popularity, it is critical to understand if these facilities can provide palliative care and a home for life for residents with dementia. Therefore, factors surrounding palliative care in these innovative facilities, including the quality of palliative care and what can be improved, need to be identified [1, 10].
To live within these small-scale settings until death, a palliative approach is essential, as it promotes a focus on person-centred, family-centred and holistic care while trying to improve the quality of dying [11, 12]. Palliative care is also essential for providing residents with peace at the end of life, as only half of individuals with dementia in long-term care die peacefully, according to their families [13]. The quality of care that residents receive toward the end of life is also a more relevant care goal than increasing the length of residents’ lives due to the complicated nature and symptom burden associated with dementia [12, 14, 15].
No review has yet to be completed on the topic of palliative care in small-scale facilities. Our purpose in conducting a scoping review was to identify the current body of knowledge and to identify research gaps in this field. Our research question was “To what extent are palliative care approaches reported in small-scale home-like facilities internationally?”
Methods
We conducted a scoping review to identify the available literature and determine how palliative care approaches are used in small-scale facilities [16, 17]. Our search strategy and review were based on the framework proposed by the Joanna Briggs Institute Reviewers Manual for scoping reviews [17]. This framework proposes enhancements made to Arksey and O’Malley’s framework [16]. We followed the recommended steps of (1) defining the objectives and research questions, (2) developing inclusion criteria and aligning them with the research question, (3) describing a planned approach to searching, data extraction and presentation, (4) searching for evidence, (5) selecting the studies or evidence, (6) data extraction, (7) analysis of data and evidence, (8) presentation of results, and (9) connecting the evidence to the purpose of the review and stating the implications of the findings [17].
Search strategy and study identification
To identify keywords and create a search string for our literature search, Medline, Google Scholar, and CINAHL were searched to analyze the text words and abstracts of the retrieved papers. A health sciences librarian, in addition to the writers, helped define terminology and add to the search strategy. The final search used all identified terms in the steps described in Table 1.
Index terms were constructed once the search strategy was finalized in all the following databases: CINAHL, PubMed, PsycINFO, and Web of Science. Our literature search covered from 1995 onward; for the full search strategy, please see Additional File 1, PubMed Final Search Strategy. The decision to search from 1995 onward was made in partnership with research team members and a health sciences librarian who had familiarity with the literature and discussed this as an adequate timeline to explore both critical concepts identified in our study (palliative care for individuals with dementia, and small-scale dementia care facilities). We also completed an ancestry search of the reference lists of the retrieved papers. We conducted a grey literature search using the search engine Google Scholar. Our initial search was conducted in July 2019 and was updated in September 2023.
We also consulted six experts in palliative care and small-scale living home-like facilities in multiple countries (North America and Europe) to determine if they had access to additional literature focused on this subject area; four answered our inquiry.
Selection criteria
Inclusion criteria
Inclusion criteria were: (1) studies must have collected primary data; (2) the study aims had to have explicitly addressed small-scale residential models (settings that resemble home-like environments, including having a maximum of 15 residents per house or unit, having staff, residents, and their family form a household together sharing responsibilities, staff performing integrated tasks both medical and personal [3, 5]); (3) studies must have described palliative care or end-of-life care approaches; (4) study samples had to include adults aged 65 years or older; (5) studies must have focused primarily on residents with dementia; and (6) studies must have been in English, Dutch, or German languages.
Exclusion criterion
Studies could not have been conducted in a hospice or traditional long-term care facility.
Study selection
Before conducting the review, the selection criteria and review processes were discussed until a consensus was reached between BD, HV, and JM. The selection criteria were piloted in title/abstract and full-text screenings by BD, HV and JM to ensure the criteria were straightforward and to determine agreement between team members. Based on the selection criteria, one reviewer (BD) screened all titles, abstracts, and full-text articles. Two additional team members, HV and JM, each conducted title/abstract and full-text screenings on a subsection of the retrieved articles to ensure consistency and accuracy with BD’s screening decisions. HV and JM also reviewed BD’s screening decisions and notes throughout the screening process. During the screening process, articles that did not directly match the criteria or were deemed questionable by BD were reviewed individually by the three reviewers, who then met to determine the eligibility and make decisions about article inclusion. During these meetings, all decisions and questions that arose during the screening process were discussed with the team to ensure transparency and consistency and reach a consensus. Each full-text article was also discussed in meetings between the three team members (BD, HV, and JM), and an agreement was reached on which papers were to be included.
Database management
We exported the retrieved studies to Endnote X9 for management and deduplication. The review update was conducted using Covidence. Thematic analysis was performed with the assistance of NVIVO-12, which we used to open-code the extracted data and cluster the data into themes.
Data extraction
The extraction process was piloted by three reviewers (BD, HV, JM). Data from the retrieved articles were extracted and summarized by BD, and the extraction tables were reviewed for accuracy and consistency by two team members (JM and HV). We extracted the following information from each study: (1) title of the literature, (2) study design, (3) research question, (4) country of data collection, (5) study sample, (6) type of housing, (6) results and discussion, and (7) study limitations.
Analysis and synthesis of results
The extracted data were synthesized using thematic analysis, where the author read and became familiar with the data, began to open-code included studies and grouped these codes into sub-themes. The subthemes were then clustered into themes using van der Steen et al.’s [15] domains of palliative care [18]. These domains of palliative care received international consensus from experts in multiple countries in a European Association for Palliative Care (EAPC) whitepaper to promote high-quality care for individuals with dementia, as there are no preexisting guidelines for end-of-life care for individuals with dementia [15]. For an in-depth overview of van der Steen et al.’s [15]. palliative care domains for dementia, please see Table 2.
The data were reported based on the 2018 PRISMA Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist [19]. This was performed by BD and checked by JM and HV for clarity and to reach a consensus on the data charting and extraction methods.
Results
Our search retrieved a total of 800 references from PsycINFO, PubMed, CINAHL, and Web of Science databases; 213 duplicates were removed. After title and abstract screening, 99 articles met our criteria for full-text review. Figure 1 shows the PRISMA diagram [20]. Our final sample of ten reports included eight papers from the initial search and two records (one policy document and one unpublished dataset) from the grey literature.
PRISMA flow diagram [20]
The articles included in the scoping review were from Japan (6), Austria (1), the Netherlands (2), and the United States (1). Nine papers were in English, and one was in German [21]. The article in German [21] was initially translated by Google Translate, and the translation was reviewed by a research associate fluent in German. Of the ten papers, six focused on group homes (GH) in Japan, [2, 22,23,24,25,26] which house 5–9 residents with mild to moderate dementia and encourage residents to participate in activities of daily living in a home-like setting [2, 3]. The concept of group homes in Japan is similar to other homes included in this study, including small-scale facilities in the Netherlands, shared housing (WG’s) in Austria, and Green Houses in the United States, which also have shared home-like kitchen and living areas and private bedrooms and recommend participation in daily activities [3]. For the characteristics of the included reports, please see Table 3.
Study characteristics and design
Seven of the final ten reports had the primary goal of investigating palliative care in dementia [2, 21, 23,24,25, 27, 29]. Two studies [22, 28] had a more general aim in which palliative care was only mentioned briefly. The last study, Takada et al. (2022) [26] aimed to develop an advanced care planning inventory and compare this inventory to the quality of death of residents with dementia.
Four studies used qualitative techniques and explored more detailed descriptions of palliative care approaches in small-scale homes [2, 21, 22, 27]. Five studies used quantitative assessments to compare palliative care practices among a larger population [23,24,25,26, 29]. One article focused on examining palliative care practices in one home [28].
Below, we summarize findings based on van der Steen et al.’s domains of palliative care [15]. An in-depth summary of the thematic analysis results is provided in Table 4.
Domain 1: applicability of palliative care
Palliative care services are important in small-scale facilities due to residents’ increasing age and their dementia diagnosis [21, 28]. Maintaining a familiar lifestyle, minimizing discomfort, proactively utilizing medical care, and collaborating with family members are essential to end-of-life care [2].
Hirakawa et al. (2006) [23] state that despite most group homes reporting that it was possible to provide palliative care (76.4%), 27.5% of these homes would not provide this care, and only 22.3% provided end-of-life care.
Domain 2: person-centred care, communication, and shared decision-making
Having the residents’ wishes as the first priority and including residents in care was discussed in six studies. For example, asking residents’ wishes for end-of-life and incorporating wishes into regular routines, such as asking about preferences for meals, music, and activities [2, 21,22,23, 27]. In some group homes, residents regularly discussed end-of-life wishes (i.e., location of death) with other residents during regular resident council meetings [22]. Takada et al. (2022) [26] also identified a significant relationship between having conversations with residents to express end-of-life wishes (ACP-PI component) and improved quality of end-of-care (increases in the QOD-LTC scores) of individuals who had passed away in group homes in Japan.
Domain 3: advanced care planning and care goals
Managing directors (60.6%) were the primary palliative care planners in group homes and were responsible for confirming resident wishes and directing care, such as organizing staff training to prepare for resident deterioration [2, 24]. In Reitinger et al.’s (2010) study, homes described contradictory views on living wills (advanced directives). Some homes preferred living wills to be written as soon as possible (i.e., upon admission), while other homes only used them as a safeguard for the staff or did not require them at all [21].
Hirakawa et al. (2006) [23] reported that 68% of staff members asked families about their wishes for end-of-life care, and 65.5% of staff members asked residents about their wishes. Residents with dementia in many homes were viewed as capable of discussing end-of-life wishes and care planning [2, 22, 28]. Similarly, Takada et al. (2022) [26] emphasized the significance of advanced care planning for residents with dementia, as they reported that the advanced care planning practice inventory (ACP-PI) had a significant association (p < 0.001) with improvements in the quality of end of life care (QOD-LTC) of residents who had passed away in group homes.
Identifying and respecting residents’ wishes at the end of life did not occur in all group homes; for example, in Nakanishi and Honda’s (2009) [24] study of 33 end-of-life cases, residents’ preferred place of death was confirmed in only 18.2% of cases.
Domain 4: continuity of care
Group homes and green care farms aim to maintain optimal continuity of care by having staff closely observe and record resident conditions to provide detailed information to other healthcare professionals [2, 23, 27]. These collaborations included close contact between healthcare workers, physicians and psychologists. Healthcare workers shared how a guideline for end-of-life care within the home for all disciplines would be beneficial [27]. Group homes also report collaborative relationships with medical institutions, which are often mandatory; however, Hirakawa et al. (2006) [23] report that group homes with progressive end-of-life care policies were less likely to have these affiliations with in-home institutions. Managers in group homes set criteria for physicians to follow during end-of-life consultations and treatment. If the criteria were not met, physicians were replaced [2, 23].
Reitinger et al. (2010) [21] report avoiding or shortening hospitalizations of residents at the end of life with methods including encouraging residents, families, and staff to work together to maintain continuity of care by avoiding hospitalizations. This was found to be an important component of care, as hospitals were identified to not be suitable for residents with dementia as they were often left unattended and lacking in basic dignity while in this setting [2, 21]. However, group homes in Japan associated themselves with hospitals to provide end-of-life or emergent care [2, 23].
None of the 10 studies reported how the continuity of care between facilities was maintained, especially at the end of life, nor did they report barriers to care or care transfers.
Domain 5: prognostication and timely recognition of dying
Staff reported anticipating resident death through accurate assessments, such as recognizing that a decline in the residents’ appetite and changes in activities of daily living including how becoming dependent on personal hygiene signals the beginning of the end-of-life period [2, 24]. Smit et al. (2022) also described how the end-of-life phase is often short in green care farms, possibly due to the encouragement of activity up until death, and this sometimes results in deaths that are sudden and may come as a surprise to staff and family members [27].
Domain 6: avoiding overly aggressive, burdensome, or futile treatment
Avoiding aggressive treatment is achieved by carefully examining therapeutic measures; for example, care homes try to avoid hospitalization due to these environments, often leading to poor outcomes [2, 21].
However, Nakanishi et al. (2016) [25] report more frequent use of physical restraint and antipsychotics with residents in Japanese group homes than in those receiving home care (in-home long-term care support or multiple care providers). These treatments were used regardless of the professionals’ attitudes and knowledge regarding palliative and dementia care. The authors do not identify in their results why group homes have more aggressive treatments compared to other community providers [25].
Domain 7: optimal treatment of symptoms and providing comfort
Contrary to the findings of Nakanishi et al. (2016) [25], minimizing mental and physical discomfort is essential in end-of-life care. In many cases, staff compensate for decreased residents’ ability to maintain quality of life, such as assisting with impaired mobility to enhance residents’ remaining abilities [2]. Staff use many methods to provide physical and psychological comfort, such as supporting a comfortable posture, touch, and massage while providing optimal treatment for discomfort and pain [2, 23, 27].
However, in van der Steen’s (2016) [29] unpublished data from the Dutch End of Life in Dementia (DEOLD) study of 330 care homes, small-scale facilities exhibited no difference in comfort at dying but a better quality of dying compared to traditional long-term care.
Domain 8: psychosocial and spiritual support
Group homes provide residents with opportunities for discussion of feelings and provision of grief support near the end of life. These homes also promote a familiar lifestyle and comfort by encouraging interactions with other residents and maintaining familiar relationships, as this helps decrease agitation and promotes quality of life in the end-of-life period [2, 21, 23]. Similarly, Nakanishi et al. (2016) [25] found that compared to in-home and multiple small-scale home providers, residents in group homes had higher scores of interactions with their surroundings and self-expression closer to the end of life.
Group homes also report a smaller opportunity to heal religiously and provide education about property law within their facilities [23].
Domain 9: family care and involvement
Family involvement is encouraged by staff by providing the family with a bed to stay at the residents’ bedside at the end of life and encouraging the family to participate in care, such as by picking out residents’ clothes [2, 27]. Family education also includes palliative care services and objective health changes experienced by residents to help families make end-of-life care decisions [2, 23, 27]. However, Hirakawa et al. (2006) [23] found that only 37.2% of group homes within their study provided families with information about palliative care services in their homes.
Most homes focused on family involvement in medical treatment and end-of-life decision-making, including asking about wishes for their loved one’s care. These discussions were held on multiple occasions, including at the beginning of the resident’s stay and as the resident’s condition deteriorated [2, 24, 27]. In some homes, the managing director handled discrepancies between residents’ and families’ wishes [2, 24].
In many group homes, aftercare rituals and grief support for staff and families are important in honouring the resident and supporting the community after the resident’s death [21, 22]. These rituals include planning ceremonies with families and maintaining cultural practices to honour the resident’s relationships with the family, staff, and residents [22]. Group homes with more progressive policies on palliative care also reported providing more grief support to families. In contrast, only 69% of group homes reported providing this via various methods, such as phone calls [23].
Domain 10: education of the healthcare team
Nursing staff regard competence in providing care support as critical for providing end-of-life care [21]. Staff also describe feeling anxious about providing care when they lack detailed knowledge about the decline of the resident’s condition [2]. Education surrounding palliative care in group homes includes various topics, such as living wills, communication skills, mental support for residents and family, and end-of-life symptoms and care, to adequately prepare staff to provide palliative care services [23]. These educational resources have become more common in small-scale homes and are provided via various methods, such as manuals, case studies, or work experience. Teaching sessions also provide staff members with mental health support surrounding their positions as palliative care providers [2, 21, 23].
Increases in quality of life, self-expression, interaction with the surrounding environment, and exhibition of minimum negative behaviour in residents are associated with caregivers having greater knowledge and positive attitudes toward palliative and dementia care [25].
Domain 11: societal and ethical issues
Kobayashi et al. (2008) [2] describe that despite financial and staffing restrictions from the Japanese long-term care insurance system that result in these facilities being ill equipped to provide palliative care, administrators choose to provide this care to maintain residents’ quality of life until death. However, many group homes in Hirakawa et al. (2006) report that homes will only provide palliative care when the resident requires no medical intervention, there is no complaint of pain from the resident, and when there is an understanding by all parties surrounding the limitations to care that the group home can provide [23].
Takada et al. (2022) [26] was the only study to briefly address national strategies or incentives to provide palliative care. They discussed an end-of-life care bonus, which incentivized nursing homes and group homes to improve the quality of care and advanced care planning at the end of life. In particular, this study revealed that homes that received this national incentive had a significant association with higher QOD-LTC scores and, therefore, higher quality end-of-life care.
Smit et al. (2022) [27] discuss the implications of COVID-19 for end-of-life care, particularly how staff and caregivers identified barriers to providing care due to specific national guidelines implemented during the pandemic.
No papers discuss the training of caregivers during their professional education domain [15].
Discussion
Main findings
To our knowledge, this scoping review is the first to provide an overview of palliative care approaches in innovative small-scale dementia care homes. We found few studies discussing palliative care in small-scale facilities; however, the included studies identified that it is possible to provide palliative care approaches and a “home for life” for residents with dementia in these innovative facilities.
The findings in the 10 included articles suggest that it is possible to provide palliative care for individuals with dementia within innovative small-scale facilities. The homes in this review prioritized resident and family-centred palliative care approaches while providing a familiar environment for residents, avoiding hospital admissions, and providing quality psychosocial and physical care up until death [2, 21,22,23, 25, 27]. By maintaining these priorities, these small-scale homes are prioritizing a “home-for-life” principle, which involves maintaining an environment that provides comprehensive care to residents with dementia and a place where they can live and maintain their quality of life up until death [3, 7, 27, 30]. The home-for-life principle and quality palliative care approaches in these homes support residents’ and families’ wishes when they need it the most [11, 12].
Barriers to palliative care
While our results suggest that palliative care is possible in these homes, the included studies rarely discussed barriers to palliative care. Identifying and considering how barriers may influence the ability to provide quality palliative care in these settings is important. One particular barrier identified was the COVID-19 pandemic, which influenced the ability of staff to maintain resident comfort, particularly due to visitation restrictions for family caregivers [27]. Additional barriers to providing palliative care for dementia in traditional long-term care homes include time commitment, lack of equipment, and inadequate staffing [31]. Additional research is needed to identify the barriers and potential solutions in innovative small-scale facilities, including barriers newly introduced by the COVID-19 pandemic.
Palliative care approaches in small-scale facilities internationally
The papers in this review touched on all general themes of van der Steen et al.’s [15] palliative care domains for dementia and applied them to palliative care within these innovative homes. Most of the papers in this review were from Japan. Therefore, our results must be interpreted with some caution because they are likely influenced by cultural factors specific to Japanese group homes. This includes factors such as the end-of-life bonus implemented in Japan in 2006 to care homes (including group homes) to incentivize the quality of palliative care and advanced care planning in care homes toward the end of life [26, 32]. Studies in this review, such as Hirakawa et al. (2006) [23], were published in the early years of this program, and the group homes included in this paper were the only small-scale facilities in our review with strong relationships with hospitals. These relationships may provide additional care resources and relate to Japan’s national strategy for dementia, which emphasizes avoiding hospitalizations of residents by using a trained outreach team to treat individuals with dementia in the community [2, 23, 24, 32, 33]. This is particularly important for Japanese group homes, as not all group homes are constructed to provide end-of-life care and are not required to have trained medical professionals on site; this differs from other small-scale homes, such as green houses in the United States, which hold hospice principles and have some specialized palliative care training [21, 24, 28]. Avoiding hospitalizations is a common theme in many homes included in this review. This may be due to the association of hospital use with poor outcomes for residents with dementia, including aggressive treatments, functional decline, falls, and dehydration [2, 21, 34, 35]. This is consistent with our findings that many small-scale homes prioritized similar palliative care domains, such as reducing discomfort [15].
Another example of the influence of culture and end-of-life care policies on end-of-life care is how resident autonomy and advanced care planning are treated near the end of life. Hirakawa [36] describes that resident autonomy is a key factor in the cultural difference between Japan and Western Countries, as Western Countries have high respect for patient autonomy, while in Japan, when an individual lacks decision-making capacity, both the family and physicians play an important role in decision making. Hirakawa [36] also describes how patients in Japan often have submissive attitudes toward medical professionals concerning their concept of life and death. Similarly, Groenewoud et al. [37] discuss how Japanese individuals were less likely than Dutch individuals in their study to want to discuss end-of-life care in advance, and more Japanese individuals reported that they would be a burden to family members if they were dependent on help at the end of life. Nakanishi et al. [33] also explored the differences between end-of-life care policies for dementia in multiple countries using van der Steen et al.’s [15] recommendations for palliative care for dementia. Nakanishi et al. [33] found that palliative care policies vary significantly among countries, including the Netherlands, Japan, and the United States, on topics such as the applicability of palliative care, staff education, and person-centred care. This finding is consistent with that of Krikorian et al. [38], who report that ideas about a good death or end-of-life care relate to financial issues, religion, disease, and cultural factors. Despite the cultural factors that may have influenced our findings, many components of palliative care remain consistent despite cultural and geographical contexts, particularly pain and symptom control [39]. While the studies included in the review did not identify the cultural or contextual implications influencing palliative care, this research gap should be addressed in the future.
Palliative care domains for dementia
Some of van der Steen et al.’s [15] recommendations were covered to a greater extent in some of the papers included in this review. The studies included in this review did not adequately describe all palliative care components. This may be the case, as many of the studies included did not aim to describe palliative care in terms of the van der Steen et al. [15] domains. Palliative care domains such as advanced care planning, palliative care policies, and palliative care education require more research to determine how these processes occur in small-scale facilities. This is important as a focus on palliative care and improving palliative care education is needed both within small-scale facilities and at the public policy level to improve care at the end of life for individuals with dementia and reduce the emotional distress of family and staff members [40, 41].
Strengths & limitations
Strengths. We used a rigorous review approach, including using the Joanna Briggs Institute Reviewers Manual for a scoping review, to structure our search and review process [17]. The van der Steen et al.’s domains for palliative care with dementia, which we used to interpret our findings, have received international consensus from experts in multiple countries [15]. Using these domains, we identified key gaps surrounding what is currently known about palliative care approaches in these small-scale dementia care facilities.
Limitations. Only papers written in English, German, or Dutch were included in this study, which may limit the number of relevant papers included in the review. The included studies were from four high-income countries, with the majority from Japan. Thus, this paper may not account for the variation in small-scale facilities in other countries. Differences in culture, national policies, and facilities, such as access to resources, may also influence the palliative care approaches of various small-scale facilities, limiting our findings’ generalizability. For example, while there are similarities between small-scale homes, there are differences in terms of access to outdoor space, participation in group activities, staffing, and the inclusion of cultural rituals that may affect palliative care approaches in these facilities [3, 22]. The decision to have a single reviewer conduct most of our article screenings may have influenced the sensitivity of our screening process and the number of papers included in our review. However, we aimed to reduce that risk by (1) using strict selection criteria, (2) piloting our selection criteria, and (3) having two additional reviewers conduct subsections of the screening process and reviewing the screening notes and decisions made by the primary reviewer (BD).
Implications
This review identifies the current knowledge base and practices used in small-scale innovative facilities to maintain quality of life and end-of-life for residents living with dementia. The findings of our review can help inform future research in this area by identifying research gaps surrounding palliative care in these innovative facilities. Specifically, future research is needed to identify the following:
-
Outcomes of palliative care approaches in small-scale facilities compared to traditional homes.
-
Differences and similarities between countries and cultures regarding palliative care in small-scale facilities.
-
Various outcomes and practices related to palliative care in different models of small-scale living facilities (comparative evaluation). This includes research on the quality of palliative care, barriers to palliative care, advanced care planning, policies, and education.
Conclusions
This scoping review is the first of which we are aware that attempts to characterize palliative care in small-scale innovative dementia care facilities. Our results suggest that it is possible to provide palliative care and a “home for life” for individuals with dementia in these settings. This paper offers a glimpse into the palliative care approaches in these innovative facilities, particularly their focus on minimizing discomfort and prioritizing patient and family-centred care at the end of life. Most studies in this area have focused primarily on Japanese Group Homes; therefore, cultural factors may have influenced our results. Future research is, therefore, needed to understand the palliative care approaches in small-scale homes internationally and how these innovative facilities compare to traditional long-term care homes.
