Abstract
This paper reports on the research methods used in five different projects aimed at supporting people living with dementia in their everyday lives and activities of daily living. In all five projects, people living with dementia and their informal carers were involved. Applied methods ranged from passive involvement in the form of observations to very active involvement consisting of consultation rounds and think-aloud sessions. The projects highlighted that people living with dementia can still contribute to the development of solutions that support them in the self-management of their symptoms and challenges, as well as technological solutions that support them in daily living.
Introduction
Caring for older people has been an essential part of societies all over the world, yet the perspective of caring has shifted. There have been political and societal transitions and technological innovations. In addition, organizational perspectives on caring have changed as the focus has expanded from medical cure to holistic care. Furthermore, care has transitioned from passive reception to individual self-management. This shift is also evident in dementia care.
Globally, 50 million individuals were living with dementia in 2017 [1]. Caring for people living with dementia (PwD) begins at home, which is considered to be the safe haven for ageing-in-place. PwD behavioral and psychological symptoms of dementia are associated with an increased risk of nursing home admission [2].
In general, older people will age at home. Ageing comprises certain changes in life; on one hand there is an increasing level of experience, on the other a decrease in physical performance and consequently a gradual decline in physical independence. Older people accommodate to this in ways that are aligned with their lifestyle, through psychological attributes and coping (intraindividual factors) or through use of medication, support from professional care and informal care, or by environmental modifications and use of assistive technologies (extraindividual factors) [3]. All these strategies are used in order to stay independent for as long as possible. This also applies to PwD, who not only have to deal with functional decline but also with cognitive decline. The latter poses additional barriers to accommodate to the changes in life when compared to other older people.
In this paper we focus on how PwD can be involved in the development of environmental modifications, the design of technology, and medication adherence strategies so that they can positively accommodate to the changes in their lives. The goal is to describe methodologies used in these studies, which involve PwD in the development of these extraindividual factors for physical independence.
Materials and Methods
The methods used for the involvement of PwD are taken from the methodology sections as used in five different projects. The projects considered were: design of a website to provide PwD with information to age-in-place (DAD project); creating an enriched environment for older adults (BEZO project); supporting PwD in their medication adherence (MedGUIDE project); creation of a sense of home in nursing home environments (VETO project), and design of an Automated Asset Management in Nursing Homes (SCHAT project).
Description of the Projects and Participants
The DAD project took place in 2010 and was initiated on request of the Dutch Alzheimer’s Society (DAS). The knowledge and experience related to ageing-in-place for PwD needed to be extended outside the academic world to PwD, informal carers and practitioners. For this project, the DAS recruited volunteers of the society, who were active in several of the DAS working groups. The recruitment of participants was performed digitally. Three couples, in which the husband had early dementia, were willing to participate. All participants had digital skills, although the wives had become the primary operators of the personal computer. The goal was for PwD and family carers to gather and systematically order all information available at that time in a comprehensive manner for other PwD. The findings and results of this project were published by Kort and van Hoof [4].
The BEZO project was conducted from 2013 to 2015 at a nursing home in the Netherlands, which also has small scale living facilities for older people (6–10 residents per group), most of whom have dementia. The project was initiated on request of the board of directors, who aimed to transform their home into an enriched environment for the benefit of both residents and staff. The project focused on the environment in two identical common rooms in the home. The selection of the participants was based on informed consent and the willingness of the residents and/or their legal representatives who were also invited to join the project. Professionals working as caregivers in these common rooms also participated. The goal was to translate the vision of the board to enhance the indoor environmental quality of one common room for the benefit of residents and staff through design features and practical methods, while the other common room kept its status quo. No instructions were given to staff or residents after the indoor environmental quality interventions had been implemented and the one common room was modified. The results of the acoustic intervention and the participatory design approach were published by Huisman et al. in 2017 [5] and 2018 [6], respectively.
The MedGUIDE project started in 2017 and will end in 2019. Because the project is in progress, no findings and results have been published, but more information can be found on the project website [7]. Twenty-one percent of PwD are exposed to polypharmacy but their cognitive decline makes it challenging for them to self-manage their disease, including taking their medication. This project was initiated by a consortium which identified that medication adherence for PwD could be improved. This consortium consists of both businesses (in Cyprus, Norway, Switzerland and the Netherlands) and universities (in the Netherlands and Romania). End users, or primary users participating in the project, are people with early (self-reported) dementia or mild cognitive impairment who use 3 or more medicines and have a signed informed consent by them or a legal representative. Other users in the project are secondary users, being family caregivers and professional caregivers, and tertiary users, being pharmacists and medical doctors. The first phase was conducted over 9 months and included 7 persons with dementia and 10 next of kin, 8 secondary users and 5 tertiary users. PwD were interviewed at home or in a group session at the day care, while secondary and tertiary users were interviewed together on campus. The goal of the project is to develop a smart pill box platform that allows PwD to self-manage their medication intake while also providing information to secondary and tertiary users about their medication adherence.
The VETO project (Nursing Home of the Future) started in 2014 and ended in 2017 as part of a larger research program. The project focuses on the study and creation of a “sense of home” in the nursing home. The sense of home of nursing home residents is a multifactorial phenomenon important for the quality of living. This purpose of the study was to investigate the factors influencing the sense of home among older adults residing in the nursing home from the perspective of residents, their relatives and care professionals. 24 residents and 18 relatives participated in 4 nursing homes in the Netherlands in a photoproduction study with subsequent interviews [8]. The methodology had been tested before in a gerontopsychiatric nursing home population [9].
The SCHAT project (Smart Care Homes and Assistive Technologies) project started in 2015 and concluded in 2018. The project utilized a work package structure with one work package focused on older PwD and their informal caregivers [10]. The project concerns real-time location systems (RTLS) which can be implemented in aged care for monitoring persons with wandering behavior and asset management. RTLS can help retrieve personal items and assistive technologies that, when lost or misplaced, may have serious financial, economic and practical implications. Various ethical questions arose during the design and implementation phases of RTLS. The work package investigated the perspectives of various stakeholders on ethical questions regarding the use of RTLS for asset management in nursing homes. One focus group session was conducted concerning the needs and wishes of residents (n = 2) and their relatives (n = 4) [11].
In the aforementioned projects, several qualitative methods were used. An overview of the methods and instruments used is given in Table 1.
Results
Various methods could be combined in order to meet the goal of a project involving PwD and their carers. For the DAD project, PwD were observed during consultation sessions for their navigation skills and patterns using a personal computer. At the same session, PwD and their spouses were consulted about the features they liked and disliked about a selection of existing websites.
For the BEZO project, observations were made in order to score the residents’ activities and their viewing direction from the perspective of the indoor light conditions in both a modified shared living room as in a nonmodified room. These methods encompass a passive involvement of PwD. At the start of the BEZO project, the more fluently speaking residents and their relatives, as well as staff and board members, contributed to a development session for interventions to the indoor environment and the design of the common living room.
During the MedGUIDE project, observations, storytelling and the think-aloud methods were used. First, storytelling sessions were held during which the PwD spoke about the structure and routines in their daily life. The goal was to adjust the system that was to be developed to these individual needs. Moreover, PwD gave feedback using “talking sheets” which contained examples of applications and/or systems which are already used for supporting the medication adherence. These sessions were conducted at the PwD’s home to gain a better understanding of their daily routines in the search of finding reminders for medication adherence. Based on the findings of the storytelling phase, a clickable design of the MedGUIDE platform was designed, and researchers collected PwD feedback and suggestions for improvement in so-called mock-up sessions. When possible, respondents participated in both the requirements phase and the mock-up sessions.
For the VETO project, PwD, their family carers and professional carers were invited to take photographs in a study in which they had to capture the essence of their sense of home in terms of facilitators and hindrances. At the end, when the photographs were available, individual interviews about the contents of the photos were held with PwD, and focus group sessions were conducted with the carers. Finally, a comparison of findings was made.
In the SCHAT project, older PwD were involved in focus group sessions, but given the complexity and abstract levels of thinking that are required in thinking about new technologies and ethical aspects, the input was rather basic. The actual participation in the project was deemed more important than the actual contribution.
In Table 1 an overview of methods used is given.
Discussion/Conclusion
Older people with early-stage dementia are very capable of contributing as participants in scientific studies. They are able to take an active role as co-creator of solutions to accommodate to their life when living with dementia. For those PwD whose speech is still fluent and not affected by the syndrome, active engagement in interviews and focus groups should always be considered. The methods used were supported with validated instruments in order to gather the instant opinion or feeling of PwD concerning the solution developed or topic studied. People with early-stage dementia are able to share and communicate their daily life routines in spoken words. Other methods based on visual and tactile capacities could also be considered in studies, as other sensory stimuli can come into action as a way of method triangulation. Such methodologies include the use of the visual-assessment (sensing) methods, which use photos and images taken by users to express what they feel about the item or image chosen or making mood boards with PwD in order to indicate what type of interior design PwD wish [17]. Another method which should be explored in relation to the involvement of PwD in research is the LEGO Serious Play method [18], in which people are stimulated to engage in storytelling activities based on a small-scale model made with LEGO bricks (or even LEGO DUPLO bricks). Such visually enhanced methods, including the aforementioned photoproduction methodology, can also be used when PwD are not fully able to engage in lengthy interview sessions, and when they require visual support to express themselves. The goal is to move user-centered design into actual participatory design, in which the active inclusion of PwD may be seen as an emancipatory step in dealing with dementia in society. Participatory design breaks away from the traditional designer-user relationship, and the designer or design-researcher acknowledges the empirical expertise of the user on the given subject. The user is therefore participating in the process as an active co-creator, rather than as a subject of research. Apart from product design, or the design of environments, similar approaches could also be used for service design, including the creation of new health care services for older PwD that are tailored towards the actual needs.
In future studies PwD and their relatives should have a more prominent role as co-creators or co-producers of technological solutions. Researchers should be challenged to offer the most appropriate methods for this goal. Therefore, a more systematic study about the pros and cons about the various methods for co-creation sessions with PwD should be executed.
