Recruitment strategies and reach of a digital fall-prevention intervention for community-dwelling older adults

Effectiveness of the Safe Step Digital Exercise Program to Prevent Falls in Older Community-Dwelling Adults: Randomized Controlled Trial

BACKGROUND

Falls among older adults are a significant public health issue due to their high incidence, severe consequences, and substantial economic impact. Exercise programs incorporating balance and functional exercises have been shown to reduce fall rates, but adherence and scaling up the interventions remain challenges. Digital technology offers a promising avenue to deliver this type of exercise, potentially improving exercise adherence and enabling self-management of exercise in the aging population.

OBJECTIVE

This study aims to assess the effectiveness of the Safe Step app, a self-managed, unsupervised, home-based digital exercise program, in reducing fall rates or fall risk in community-dwelling older adults. Additional aims were to describe fall-related injuries in both the exercise and control groups, study attrition, and adherence to the Safe Step exercise program.

METHODS

Community-dwelling individuals, aged 70 years or older, who had experienced falls or a decline in balance in the past year were randomized to either an exercise group using the Safe Step app combined with educational videos, or a control group receiving educational videos alone. Both interventions lasted for 1 year. Information regarding fall events was self-reported monthly through questionnaires. Exercise adherence was monitored through questionnaires every third month. Negative binomial and logistic regression estimated the incidence rate ratio of fall rate and the risk ratio (RR) of experiencing falls, respectively. Fall-related injuries, study attrition, and exercise adherence were reported descriptively.

RESULTS

In total, 1628 people were enrolled in the study, 79% were women, and the mean age was 75.8 (SD 4.4) years (range 70-94 years). The intention-to-treat analysis showed no significant difference in fall rates between the exercise and control groups after 12 months (2.21 falls per person-year in the exercise group and 2.41 in the control group; incidence rate ratio 0.92, 95% CI 0.76-1.11; P=.37). The risk of experiencing at least 1 fall was significantly lower (11%) in the exercise group compared to the control group (53% vs 59.6%; RR 0.89, 95% CI 0.80-0.99; P=.03). No differences were observed regarding the risk of 2 or more falls (34.1% in the exercise group, 37.1% in the control group; RR 0.92, 95% CI 0.79-1.06; P=.23). Injurious fall rates were similar between the exercise and control group. During the trial, 161 (20%) participants from the exercise group and 63 (8%) from the control group formally withdrew. The proportion of exercise group participants meeting the 90-minute weekly exercise goal was 12.7%, 13.4%, 8.6%, and 9.1% at 3, 6, 9, and 12 months, respectively.

CONCLUSIONS

Access to a self-managed unsupervised digital exercise program can be an effective component of a primary fall prevention strategy for community-dwelling older adults. Further research is needed to explore the mediating factors that influence the outcomes and develop strategies that enhance adherence for optimal impact in this population.

Online-Based Recruitment Methods for Community-Dwelling Older Adults: Scoping Review and Lessons Learned From the PLAN Trial

BACKGROUND

Despite rapid technological advancement and a considerably aging US population, there remains a gap in the literature pertaining to online-based recruitment strategies for older adults.

OBJECTIVE

This study aimed to describe the lessons learned from the authors' experience of recruiting a sample for PLAN (Preparing successful aging through dementia Literacy education And Navigation), an ongoing, community-based randomized controlled trial designed to promote the transition of community-dwelling Korean American older adults with probable dementia and their caregivers into the health care system. The authors also present online-based recruitment strategies focused on older adults reported in relevant published studies to compare with their experiences.

METHODS

Data sources included PLAN recruitment tracking files, study team meeting minutes, and interviews with community consultants. We also conducted a scoping review of published studies, searching PubMed in July 2021, and updated our search in September 2023. Eligibility criteria included (1) focus on older adults aged more than 65 years, (2) sample recruited from a community setting, and (3) inclusion and description of online-based recruitment strategies. Exclusion criteria (1) did not focus on adults older than 65 years in a community setting, (2) did not include or describe online-based recruitment strategies, or (3) used online-based methods but not for the purpose of recruitment. The review followed the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews). Information was extracted using a data charting table and synthesized by conducting a thematic analysis.

RESULTS

In total, 8 articles were included in the scoping review and primarily addressed health promotion and recruitment strategy evaluation. When compared with PLAN data sources, five key themes emerged as relevant to the online-based recruitment of community-dwelling older adults: (1) unfamiliarity with technology-limited digital literacy, (2) differences in internet access and use across older age groups, (3) providing technological support to promote recruitment, (4) successful and unsuccessful recruitment using social media, and (5) other diverse online-based methods of recruitment. In particular, direct quotes from multiple sources for the PLAN trial revealed technological challenges that were common among immigrant older adults as the study team used various online-based recruitment activities.

CONCLUSIONS

The literature was limited in the discussion of online-based recruitment among older participants. Data sources revealed the digital divide and limited digital literacy, particularly among non-English-speaking immigrant older adults and their caregivers. The usefulness of online-based recruitment of older adults is uncertain due, in large part, to limited sociodemographic diversity noted in the samples recruited in the included studies. Future research should explore the role of race and ethnicity and other characteristics, such as socioeconomic status, sex, education, access to technology, and digital literacy, in relation to online-based recruitment for adequate representation of diverse older adults in research.

A qualitative study of recruitment strategies: Perspectives from older adults living with diabetes

AIMS

There is a need to increase representation of diverse older adults in health-related qualitative research to better understand and improve chronic disease care over the lifespan. Our aim was to elicit perspectives about research recruitment among a diverse sample of older adults with diabetes participating in a qualitative study.

METHODS

Older adults with diabetes and caregivers were recruited through purposive sampling for semi-structured interviews focused on diabetes self care. Six questions were used to explore recruitment strategies and recommendations for engaging older adults in research. We analysed interview transcripts using descriptive analysis to identify themes related to engaging older adults in research studies.

RESULTS

Seventeen older adults with diabetes and three caregivers participated (N = 20). Descriptive analysis revealed four themes: (1) Recruitment of older adults requires varied strategies to overcome barriers to engagement and participation; (2) Building and leveraging personal relationships is central to successful recruitment; (3) Transparent communication about the research process and value of the study is needed to inform and motivate older adults to participate; and (4) Research offers a connection to a broader community: sharing, learning and helping others.

CONCLUSIONS

We found four main themes related to the complexity of recruiting older adults for research studies. These insights may inform more effective, equitable and inclusive recruitment efforts targeted at older adults in the future.

Comparison of digital recruitment strategies for Alzheimer's disease patients

Objectives

Clinical trials studying Alzheimer's Disease (AD) face the challenge of recruiting participants with significant barriers to entering research studies. The objective of this study is to compare digital recruitment strategies' ability to recruit older adults with cognitive impairment (CI).

Methods

Older adults with CI were recruited for a clinical trial studying vestibular therapy in reducing falls and improving balance and cognition in older adults with CI. Potential participants were recruited via two different digital recruitment methods, a direct messaging campaign using established patient records and a social media campaign. Potential participants then filled out surveys to determine eligibility for the study.

Results

The direct messaging campaign contacted 3060 potential participants and the social media campaign resulted in 8265 instances of unique engagement. Of the number of people reached, the direct messaging campaign had a higher percentage of people who submitted the survey compared to the social media campaign (8.3% vs. 1.2%, p < 0.001). There was no significant difference in age, race, ethnicity, education, household income, and insurance status between the recruitment groups (p > 0.05). Direct messaging recruitment proved more cost-effective at $21.74 per eligible participant compared to the social media campaign at $859.58 per eligible participant.

Conclusion

This study found that direct messaging recruitment using established patient records was more cost-effective compared to social media recruitment for this clinical trial. In this sample size, similar demographics were reached by both recruitment methods. Future studies should continue to explore the use of social media and alternative methods to recruit representative participant populations for ongoing AD research.

'Maintaining balance in life'-exploring older adults' long-term engagement in self-managed digital fall prevention exercise

BACKGROUND

Accidental falls are one of the greatest threats to older adults' health and well-being. The risk of falling can be significantly reduced with strength and balance interventions. However, there needs to be further knowledge into how older adults can be supported to achieve a maintained exercise behaviour. Therefore, the aim of this study was to explore factors that enabled older adults to maintain their exercise during a 1-year self-managed digital fall prevention exercise intervention.

METHODS

This study used a grounded theory methodology. Semi-structured individual interviews were conducted by phone or conference call. Eighteen community-dwelling older adults aged 70 years or more participated. The participants had a self-reported exercise dose of 60 min or more per week during the last three months of participation in a 12-months intervention of self-managed digital fall prevention exercise, the Safe Step randomized controlled trial. Open, axial, and selective coding, along with constant comparative analysis, was used to analyze the data.

RESULTS

The analysis resulted in a theoretical model. We found that the fall prevention exercise habits of adults were developed through three stages: Acting against threats to one's own identity, Coordinating strategies to establish a routine, and Forming habits through cues and evaluation. The main category of Maintaining balance in life encases the participants transition through the three stages and reflects balance in both physical aspects and in between activities in daily life. The process of maintaining balance in life and desire to do so were mediated both by intrinsic person-dependent factors and the Safe Step application acting as an external mediator.

CONCLUSION

This study identified three stages of how older adults developed self-managed fall prevention exercise habits, supported by a digital application. The generated theoretical model can inform future interventions aiming to support long-term engagement in digitally supported and self-managed fall prevention interventions.
