Aging in place among home-dwelling older adults in Canton Basel-Landschaft: the INSPIRE Population Survey

Due to medical and technological advancements, many individuals in countries around the world are living longer (1). In Switzerland between 2020 and 2050, a rise from 18% to 26% for those aged 65 years or older and from 5% to 11% for those aged 80 years and older is foreseen (2). The gains in life expectancy, although a positive outcome, are not always enjoyed in full health and free of limitations. As individuals age, many of them may suffer from the presence of multi-morbidity and frailty (3, 4). Functional limitations as well as isolation and loneliness are also frequently reported among this population (3, 5-7). Moreover, these individuals usually receive care from different providers across various settings which can lead to their care being fragmented (8). Fragmentation of care is characterized by gaps in provision of care which could cause confusion and distress for older adults and their caregivers, as well as higher costs associated with unnecessary use of services (9). Despite challenges associated with aging, many older individuals prefer to remain living in their own environments for as long as possible (10, 11), an objective known as aging in place (12). Aging in place is linked to the ability to maintain independence and live a thriving and highly qualitative life within an individual’s own environment (13). It can therefore be fostered by designing environments that facilitate the mobility and engagement in social activities, which are important components for the health and quality of life of older adults (14). There is also an opportunity for countries to exploit existing and new assistive technologies, another pertinent facilitator of aging in place (15). Assistive technologies are an umbrella term including any device, equipment, instrument or software whose purpose is to maintain or improve an individual’s functional status and independence (16). To assist older adults to age in place and address their complex needs, the World Health Organization (WHO) has proposed an integrated care approach to support older adults’ independence and make aging in place possible (8, 17). Integrated care models are complex, dynamic interventions targeting multiple levels of the healthcare system, which often entail behavior change in the way various health and social care providers provide joint care (18, 19). To successfully develop and implement an integrated model of care, not only the perspectives of the healthcare providers, social care professionals or policymakers are essential, but also the needs and preferences of older adults and their informal caregivers (15, 20). Understanding the demographic and social characteristics of a target population, is also fundamental in planning, developing and implementing integrated care for older people (21). In 2018, an opportunity for integrated care for home-dwelling older adults was put forward by a new care law in Canton Basel-Landschaft in Switzerland (22). The INSPIRE project is working together with the local policymakers to support the development, implementation and evaluation of an integrated care model for home-dwelling adults aged 75 and above living in this region (23). The INSPIRE project is an implementation science project, positioned within the three phases (development, feasibility and effectiveness evaluation) of the Medical Research Council (MRC) for developing and implementing complex interventions (18). The project incorporates the recommendations of the MRC framework with several implementation science components such as contextual analysis, stakeholder involvement, as well as using implementation strategies and implementation outcomes to ensure the successful implementation and sustainability of the care model in Canton BL. During the development phase, an understanding of the context aids in ensuring the suitability of the intervention components for the implementation setting (23, 24). Therefore, we conducted the INSPIRE Population Survey (25, 26) as part of the contextual analysis, with the aim to understand the needs and preferences of older adults, as well as the support and services they currently require and anticipate needing in the future to maintain their independence and make aging in place possible. The overall goals of this dissertation are threefold. First, we aimed to describe the development of the INSPIRE Population Survey and the marketing strategy we used to reach as many home-dwelling older adults as possible, a population that is known to be challenging to recruit in research (27). Second, we used an ecological approach to dive deeper into the health-related quality of life of this population, as one of the main goals of aging in place. Finally, we investigated factors associated with openness to use assistive technologies that can facilitate independence among home-dwelling older adults and support them to age in place. Chapter 1 provides a general overview of challenges associated with caring for an aging population as well as the opportunities for integrated care for aging in place among home-dwelling older adults. The current literature on the concepts of quality of life and health-related quality of life, as well as the current state of the art on assistive technologies facilitating the autonomy of older adults is also provided. Chapter 2 follows with the dissertation aims. Chapter 3 chronicles the research conducted to develop the INSPIRE Population Survey, as well as an outline of the variables and measurements used in the survey (25). The work also describes the marketing strategy used for disseminating the survey and briefly reports on the response rate and participant characteristics. This population-based survey achieved a response rate of 30.7%, which is considerably high for postal surveys (28), particularly in those involving older adults (27). This accomplishment can be credited to the ongoing stakeholder involvement strategies we used, including early engagement of all stakeholders during the development of the questionnaire as well as its marketing. In Chapter 4, we evaluated HRQoL and factors related to it using an ecological outlook. The participants of our survey reported a high HRQoL, similar to findings from previous research (29, 30). We specifically looked at multilevel factors at the micro, meso and macro level related to how home-dwelling older adults perceived their HRQoL. This ecological perspective permitted the investigation of variables associated not only with the individual, but also with the environment around the older adult. We confirmed that among home-dwelling older adults, having a higher income, supplementary insurance, better education and generally a greater socio-economic status were associated with a higher HRQoL (31, 32). Our findings also validated previous studies indicating that individuals who report to be more frequently involved in one or more social activities, correspondingly report a higher HRQoL (33, 34). We also confirmed factors that negatively impact home-dwelling older adults’ HRQOL, as previously researched, like being older and female, having multimorbidity and polypharmacy, and being lonely or socially isolated (35-46). Chapter 5 presents the results from our study aiming to describe the current and anticipated use of assistive technologies among our participants, namely telemedicine, phone/SMS, wearables and assistive robots; as well the factors associated with openness to use such assistive technologies. We showcased that the current use of assistive technologies was rather low amid participants, compared to findings from two other surveys conducted on this topic among Swiss older adults (47, 48). Our results highlight a new finding that compared to current use, a higher percentage of home-dwelling older adults were open to using wearables and telemedicine in the future. We also found that openness to use assistive technologies in this population was positively associated with their current use, and also with receiving support from a spouse or a partner. Similar to the two previous surveys in Switzerland, openness to use assistive technologies was negatively associated with older age and with being female (47, 48). Chapter 6 presents a summary of the findings from the three preceding chapters and interprets them in the context of the current literature. Furthermore, methodological strengths and limitations of these studies are discussed. At last, reflections on the implication of this thesis for future research, policy and practice are presented. In conclusion, this dissertation was part of the development phase of an implementation science project aiming to implement and sustain an integrated care model for home-dwelling older adults. Our findings provide some important insight into the areas requiring the attention of care professionals and policymakers. We brought forward the need for considering the role the environment and the social network surrounding home-dwelling older adults play in fostering care that augments their quality of life and supports them in maintaining their desired independence. We also showed the potential assistive technologies have in attaining this goal, possibly also alleviating some of the burden of informal caregivers who are providing care and support for home-dwelling older adults. From a research, practice and policy position, we believe our findings have the prospective to provide a better scientific and policy approach in assuring older adults are reaching their goal to age in place

Protocol for a mixed methods feasibility and implementation study of a community-based integrated care model for home-dwelling older adults: The INSPIRE project

Evaluations of integrated care models for home-dwelling frail older adults have shown inconclusive results on health and service outcomes. However, limited research has focused on the implementation of integrated care models. Applying implementation science methods may facilitate uptake of integrated care models, thus generating positive outcomes e.g., reduced hospital admissions. This paper describes the protocol to assess the feasibility of an integrated care model (featuring a four-step comprehensive geriatric assessment: screening, a multi-dimensional assessment, a coordinated individualized care plan and follow-up) designed for a new community-based center for home-dwelling older adults in Switzerland. The study includes the following objectives: 1) to assess implementation by a) monitoring respondents to the outreach strategies and describing the Center's visitors; b) assessing implementation outcomes related to the care model (i.e., adoption, acceptability, feasibility, fidelity) and implementation processes related to collaboration; and 2) assessing implementation costs.; For objective 1a, we will use a descriptive design to assess respondents to the outreach strategies and describe the Center's visitors. We will use a parallel convergent mixed methods design for objective 1b. Implementation outcomes data will be collected from meetings with the Center's staff, interviews with older adults and their informal caregivers, and reviewing older adults' health records at the Center. Implementation processes related to collaboration will be assessed through a questionnaire to external collaborators (e.g., GPs) towards the end of the study. For objective 2, implementation costs will be calculated using time-driven activity-based costing methods. Data collection is anticipated to occur over approximately six months.; This study of a contextually adapted integrated care model will inform adaptations to the outreach strategies, care model and implementation strategies in one community center, prior to evaluating the care model effectiveness and potentially scaling out the intervention.; Feasibility study registration ID with clinicaltrials.gov: NCT05302310; registration ID with BMC: ISRCTN12324618

Factors associated with health-related quality of life among home-dwelling older adults aged 75 or older in Switzerland: a cross-sectional study

HRQoL is an indicator of individuals' perception of their overall health, including social and environmental aspects. As a multidimensional concept, HRQoL can be influenced by a multitude of factors. Studies of HRQoL and factors associated with it among home-dwelling older adults have often been limited to inpatient settings or to a sub-population with a chronic disease. Studying HRQoL and its correlating factors among this population, by providing an ecological lens on factors beyond the individual level, can provide a better understanding of the construct and the role of the environment on how they perceive their HRQoL. Thus, we aimed to assess the HRQoL and investigate the correlates of HRQOL among home-dwelling older adults, guided by the levels of the ecological model.; This is a cross-sectional population survey conducted in 2019 in Canton Basel-Landschaft, in northwestern Switzerland, and includes a sample of 8786 home-dwelling older adults aged 75 and above. We assessed HRQoL by using the EQ-index and the EQ-VAS. The influence of independent variables at the macro, meso and micro level on HRQoL was tested using Tobit multiple linear regression modelling.; We found that having a better socio-economic status as denoted by higher income, having supplementary insurance and a higher level of education were all associated with a better HRQoL among home-dwelling older adults. Furthermore, being engaged in social activities was also related to an improved HRQoL. On the other hand, older age, female gender, presence of multimorbidity and polypharmacy as well as social isolation and loneliness were found to all have a negative impact on HRQoL.; Understanding factors related to HRQoL by using an ecological lens can help identify factors beyond the individual level that impact the HRQoL of home-dwelling older adults. Our study emphasises the importance of social determinants of health and potential disparities that exists, encouraging policymakers to focus on policies to reduce socio-economic disparities using a life-course approach, which consequently could also impact HRQoL in later stages of life

Health and social care of home-dwelling frail older adults in Switzerland : a mixed methods study

Home-dwelling frail older adults are often faced with multimorbidity and complex care needs, requiring health and social care systems that support frail older adults to age in place. The objective of this paper was to investigate the types of formal health and social care as well as informal care and social support used by home-dwelling frail older adults; whether they perceive their support as sufficient; and their experience with and preferences for care and support

Implementation fidelity of a multifactorial in-hospital fall prevention program and its association with unit systems factors: a single center, cross-sectional study

Falls are a common, costly global public health burden. In hospitals, multifactorial fall prevention programs have proved effective in reducing falls' incidence; however, translating those programs accurately into daily clinical practice remains challenging. This study's aim was to identify ward-level system factors associated with implementation fidelity to a multifactorial fall prevention program (StuPA) targeting hospitalized adult patients in an acute care setting.; This retrospective cross-sectional study used administrative data on 11,827 patients admitted between July and December 2019 to 19 acute care wards at the University Hospital Basel, Switzerland, as well as data on the StuPA implementation evaluation survey conducted in April 2019. Data were analysed using descriptive statistics, Pearson's coefficients and linear regression modelling for variables of interest.; The patient sample had an average age of 68 years and a median length of stay of 8.4 (IQR: 2.1) days. The mean care dependency score was 35.4 points (ePA-AC scale: from 10 points (totally dependent) to 40 points (totally independent)); the mean number of transfers per patient -(e.g., change of room, admission, discharge) was 2.6 (range: 2.4- 2.8). Overall, 336 patients (2.8%) experienced at least one fall, resulting in a rate of 5.1 falls per 1'000 patient days. The median inter-ward StuPA implementation fidelity was 80.6% (range: 63.9-91.7%). We found the mean number of inpatient transfers during hospitalisation and the mean ward-level patient care dependency to be statistically significant predictors of StuPA implementation fidelity.; Wards with higher care dependency and patient transfer levels showed higher implementation fidelity to the fall prevention program. Therefore, we assume that patients with the highest fall prevention needs received greater exposure to the program. For the StuPA fall prevention program, our results suggest a need for implementation strategies contextually adapted to the specific characteristics of the target wards and patients
