Barriers and facilitators for implementation of a combined lifestyle intervention in community-dwelling older adults: a scoping review

Digital Multidomain Lifestyle Intervention for Community-Dwelling Older Adults: A Mixed Methods Evaluation

Objectives

As life expectancy rises at a faster rate than healthy life expectancy, there is a global need for scalable and cost-effective interventions that enhance the health-related quality of life of older adults. This study aimed to examine the user experience and usability of a 12-week digital multidomain lifestyle intervention in community-dwelling older adults aged 65 years and above.

Methods

The intervention was developed involving older adults and delivered through a mobile application (app) focusing on physical activity, nutrition, sleep and mindfulness/relaxation. We used a mixed methods sequential explanatory approach to evaluate the user experience and usability of the intervention. We delivered online questionnaires before and after the intervention, collected app usage data and conducted semi-structured interviews.

Results

One hundred eight older adults participated in the study. Fifty-six percent of participants completed the 12-week intervention. Users who completed the intervention experienced it as highly satisfactory and rated the usability as high. User engagement was particularly high for the physical activity content.

Conclusion

Although participant retention can be a challenge, a digital multidomain lifestyle intervention developed involving community-dwelling older adults can lead to positive user experience and high usability.

A qualitative study on the impact and participation in the AGELESS multidomain intervention: Insights from older adults with cognitive frailty and their caregivers

BACKGROUND

Cognitive frailty (CF) is a major precursor to dementia, and multidomain interventions have the potential to delay, prevent or reverse its early onset. However, the successful translation and sustainability of such interventions in real-life settings remain uncertain. In this study, we aimed to explore the insights of older adults with CF and their caregivers regarding the impact and participation in the AGELESS multidomain intervention.

METHODS

This qualitative study was conducted following the completion of AGELESS multidomain intervention. Semi-structured interviews covering domains such as perceptions, benefits, barriers, facilitators, and program preferences were conducted among 17 older adults with CF and 10 caregivers following the completion of the intervention. The data obtained were transcribed verbatim and analyzed using thematic analysis. Each transcript was reviewed and coded to identify prevailing themes derived from the interview data.

RESULTS

The analysis revealed five distinct themes: (1) impact of the program, (2) facilitators enhancing participation, (3) barriers hindering participation, (4) suggestions for improving participation and (5) challenges to adopt digital platforms. Based on the findings, the AGELESS multidomain intervention had a positive impact on the participants and their caregivers. It was noted that they showed preference for in-person sessions over virtual ones. The study highlighted key factors critical for successful participation, including diversity and inclusivity. It emphasized incorporating a multi-component, group-based approach with social aspects. The intervention should be people-centered, dignified, affordable, and customized to meet the unique needs of each participant.

CONCLUSIONS

The AGELESS multidomain intervention was well received by older adults with CF and their caregivers who participated in this study. Moving forward, it is recommended that future initiatives focus on identifying opportunities to implement existing evidence-based programs on a larger scale for the prevention of dementia in older adults.

Identification and development of implementation strategies: the important role of codesign

Background

To date, implementation strategies reported in the literature are commonly poorly described and take the implementation context insufficiently into account. To unravel the black box of implementation strategy development, insight is needed into effective theory-based and practical-informed strategies. The current study aims to describe the stepwise development of a practical-informed and theory-based implementation strategy bundle to implement ProMuscle, a nutrition and exercise intervention for community-dwelling older adults, in multiple settings in primary care.

Methods

The first four steps of Implementation Mapping were adopted to develop appropriate implementation strategies. First, previously identified barriers to implementation were categorized into the constructs of the Consolidated Framework for Implementation Research (CFIR). Second, the CFIR-ERIC matching tool linked barriers to existing implementation strategies. Behavioral change strategies were added from the literature where necessary. Third, evidence for implementation strategies was sought. Fourth, in codesign with involved healthcare professionals and implementation experts, implementation strategies were operationalized to practical implementation activities following the guidance provided by Proctor et al. These practical implementation activities were processed into an implementation toolbox, which can be tailored to a specific context and presents prioritized implementation activities in a chronological order.

Results

A previous study identified and categorized a total of 654 barriers for the implementation of a combined lifestyle intervention within the CFIR framework. Subsequently, the barriers were linked to 40 strategies. Due to the fact that many strategies impacted multiple barriers, seven overarching themes emerged based on the strategies: assessing the context, network internally, network externally, costs, knowledge, champions, and patient needs and resources. Codesign sessions with professionals and implementation experts resulted in the development of supported and tangible implementation activities for the final 20 strategies. The implementation activities were processed into a web-based implementation toolbox, which allows healthcare professionals to tailor the implementation activities to their specific context and guides healthcare professionals to prioritize implementation activities chronologically during their implementation.

Conclusion

A theory-based approach in combination with codesign sessions with stakeholders is a usable Implementation Strategy Mapping Method for developing a practical implementation strategy bundle to implement ProMuscle across multiple settings in primary care. The next step involves evaluating the developed implementation strategies, including the implementation toolbox, to assess their impact on the implementation and adoption of ProMuscle.
