Recruiting Older Adults With Functional Difficulties Into a Community-Based Research Study: Approaches and Costs

Community-based complex interventions to sustain independence in older people, stratified by frailty: a systematic review and network meta-analysis

Background

Sustaining independence is important for older people, but there is insufficient guidance about which community health and care services to implement.

Objectives

To synthesise evidence of the effectiveness of community services to sustain independence for older people grouped according to their intervention components, and to examine if frailty moderates the effect.

Review design

Systematic review and network meta-analysis.

Eligibility criteria

Studies: Randomised controlled trials or cluster-randomised controlled trials. Participants: Older people (mean age 65+) living at home. Interventions: community-based complex interventions for sustaining independence. Comparators: usual care, placebo or another complex intervention.

Main outcomes

Living at home, instrumental activities of daily living, personal activities of daily living, care-home placement and service/economic outcomes at 1 year.

Data sources

We searched MEDLINE (1946-), Embase (1947-), CINAHL (1972-), PsycINFO (1806-), CENTRAL and trial registries from inception to August 2021, without restrictions, and scanned reference lists.

Review methods

Interventions were coded, summarised and grouped. Study populations were classified by frailty. A random-effects network meta-analysis was used. We assessed trial-result risk of bias (Cochrane RoB 2), network meta-analysis inconsistency and certainty of evidence (Grading of Recommendations Assessment, Development and Evaluation for network meta-analysis).

Results

We included 129 studies (74,946 participants). Nineteen intervention components, including 'multifactorial-action' (multidomain assessment and management/individualised care planning), were identified in 63 combinations. The following results were of low certainty unless otherwise stated. For living at home, compared to no intervention/placebo, evidence favoured: multifactorial-action and review with medication-review (odds ratio 1.22, 95% confidence interval 0.93 to 1.59; moderate certainty) multifactorial-action with medication-review (odds ratio 2.55, 95% confidence interval 0.61 to 10.60) cognitive training, medication-review, nutrition and exercise (odds ratio 1.93, 95% confidence interval 0.79 to 4.77) and activities of daily living training, nutrition and exercise (odds ratio 1.79, 95% confidence interval 0.67 to 4.76). Four intervention combinations may reduce living at home. For instrumental activities of daily living, evidence favoured multifactorial-action and review with medication-review (standardised mean difference 0.11, 95% confidence interval 0.00 to 0.21; moderate certainty). Two interventions may reduce instrumental activities of daily living. For personal activities of daily living, evidence favoured exercise, multifactorial-action and review with medication-review and self-management (standardised mean difference 0.16, 95% confidence interval -0.51 to 0.82). For homecare recipients, evidence favoured the addition of multifactorial-action and review with medication-review (standardised mean difference 0.60, 95% confidence interval 0.32 to 0.88). Care-home placement and service/economic findings were inconclusive.

Limitations

High risk of bias in most results and imprecise estimates meant that most evidence was low or very low certainty. Few studies contributed to each comparison, impeding evaluation of inconsistency and frailty. Studies were diverse; findings may not apply to all contexts.

Conclusions

Findings for the many intervention combinations evaluated were largely small and uncertain. However, the combinations most likely to sustain independence include multifactorial-action, medication-review and ongoing review of patients. Some combinations may reduce independence.

Future work

Further research is required to explore mechanisms of action and interaction with context. Different methods for evidence synthesis may illuminate further.

Prevention at home in older persons with (pre-)frailty: analysis of participants' recruitment and characteristics of the randomized controlled PromeTheus trial

BACKGROUND

The "PromeTheus" trial is evaluating a home-based, multifactorial, interdisciplinary prevention program for community-dwelling (pre-)frail older adults. These individuals often suffer from reduced participation, which can complicate the recruitment and enrollment in a clinical trial.

AIMS

The aim of this study was to evaluate different recruitment strategies and differences in participant characteristics in relation to these strategies.

METHODS

This cross-sectional study used baseline data from the randomized-controlled PromeTheus trial, in which community-dwelling (pre-)frail older persons (Clinical Frailty Scale [CFS] 4-6 pt., ≥ 70 years) were recruited via general practitioners ("GP recruitment") or flyers, newspaper articles, and personalized letters ("direct recruitment"). Differences in the sociodemographic, clinical, physical, functional, mobility-related, psychological and social characteristics were analyzed in relation to the recruitment strategy.

RESULTS

A total of 385 participants (mean age = 81.2, SD 5.9 years; women: n = 283, 73.5%) were enrolled, of which 60 (16%) were recruited by GPs and 325 (84%) through direct recruitment. Participants recruited via GPs had significantly higher subjective frailty levels (CFS), were more often physically frail (Fried Frailty Phenotype), and showed lower physical capacity (Short Physical Performance Battery), participation (disability component of the short version of the Late-Life Function and Disability Instrument), and life-space mobility (Life-Space Assessment) compared to those recruited via the direct approach (p = 0.002-0.026). Costs per randomized participant were 94€ for the GP recruitment strategy and €213 for the direct recruitment strategy.

CONCLUSION

Different strategies may be required to successfully recruit (pre-)frail home-living older adults into preventive programs. Direct recruitment strategies, in which potential participants are directly informed about the prevention program, seem to be more promising than GP recruitment but may result in enrolment of persons with less functional impairment and higher recruitment costs.

Self-management by older people living with cancer and multi-morbidity: a qualitative study

PURPOSE

Over half of individuals diagnosed with cancer are aged over 70 years, and more than 75% of those with cancer report at least one other medical condition. Having multiple conditions alongside cancer in old age may lower functional status, greater likelihood of treatment complications and less favourable prognoses. This qualitative study explored how older people with long-term chronic conditions manage their health and meet their health-related goals after they have completed treatment for cancer.

METHODS

One-to-one face-to-face qualitative interviews were conducted with 8 older people and 2 informal caregivers based in the UK. Older adults were eligible to participate if they were over 70 and had completed primary cancer treatment with curative intent and had at least one other chronic health condition. A semi-structured interview schedule developed a priori based on Shippee's cumulative complexity model was used. We aimed to explore experiences that could influence self-management, utilisation of healthcare services and health outcomes. A framework analysis was used to describe and interpret the data.

RESULTS

Four overarching themes were identified in the analysis. These themes related to factors that influenced the everyday health-related workload and capacity of the participants. These factors included their health, resources, and opportunities, as well their motivation and sense of perceived control over their lives.

CONCLUSIONS

Fragmented healthcare systems and relationships with healthcare professionals also influenced the participants' self-management of their health. Our findings highlight the interaction between an individuals' needs, capacity, treatment burden, and the services and resources available to them. These findings support calls to promote person-centred care to better support older adults to manage their health.

Aging Gracefully in Place: An Evaluation of the Capability of the CAPABLE© Approach

As American adults live longer, society must prioritize effective strategies promoting safe aging-in-place and decreasing institutional health care costs. Social determinants of health, especially housing, critically influence older adult health, particularly for disadvantaged, low-income older adults. Johns Hopkins University developed Community Aging in Place-Advancing Better Living for Elders (CAPABLE^©), a client-centered, home-based program to improve older adults' function and capacity to age in place. This evaluation studied CAPABLE's long-term effectiveness in four distinct locations in California, North Carolina, Pennsylvania, and Vermont. Seven months after CAPABLE, intervention group participants experienced greater improvements than the control group in activities of daily living limitations (2-point vs. 0.7-point improvement, p = .012), falls efficacy (8.9-point improvement vs. 0.1-point worsening, p = .012), depression (1.3-point improvement vs. 0.4-point worsening, p = .021), and pain (1.5-point improvement vs. 0.3-point worsening, p = .002). These results add to existing research on short-term effectiveness in urban locales, showing CAPABLE yields long-term health improvement for older adults in micropolitan and small urban locations, with different implementation organizations, housing stocks, and clients.

Evaluation of Implementing TOM: A Group-Based Fall Prevention Programme among Community-Dwelling Older Adults in The Netherlands

There is strong evidence that effective fall prevention elements exist, but the implementation into society remains difficult. The aim of the current study is to describe and evaluate the implementation of the fall prevention programme "Thuis Onbezorgd Mobiel" (TOM). This novel approach combines effective components into a multidisciplinary group-based programme for adults aged 65 years or older with an increased risk of falling. To investigate the impact on several health-related outcomes such as subjective health, quality of life, physical functioning, and falls, we applied a quasi-experimental pre-post design including a follow-up period. A total of 164 older adults subscribed to the programme: 80 were eligible to start and 73 completed it. The impact analysis revealed a significant improvement in subjective health, physical functioning, and quality of life directly after participating in the programme. The impact on subjective health and quality of life persisted six months after the programme. Important facilitators for the implementation of the programme were social contact and clear communication. Lack of a concrete follow-up was seen as an important barrier. The results of the current research help guide further implementation of effective fall prevention interventions in practice.

The Tribulations of Trials: Lessons Learnt Recruiting 777 Older Adults Into REtirement in ACTion (REACT), a Trial of a Community, Group-Based Active Aging Intervention Targeting Mobility Disability

BACKGROUND

Challenges of recruitment to randomized controlled trials (RCTs) and successful strategies to overcome them should be clearly reported to improve recruitment into future trials. REtirement in ACTion (REACT) is a United Kingdom-based multicenter RCT recruiting older adults at high risk of mobility disability to a 12-month group-based exercise and behavior maintenance program or to a minimal Healthy Aging control intervention.

METHODS

The recruitment target was 768 adults, aged 65 years and older scoring 4-9 on the Short Physical Performance Battery (SPPB). Recruitment methods include the following: (a) invitations mailed by general practitioners (GPs); (b) invitations distributed via third-sector organizations; and (c) public relations (PR) campaign. Yields, efficiency, and costs were calculated.

RESULTS

The study recruited 777 (33.9% men) community-dwelling, older adults (mean age 77.55 years (SD 6.79), mean SPPB score 7.37 (SD 1.56)), 95.11% white (n = 739) and broadly representative of UK quintiles of deprivation. Over a 20-month recruitment period, 25,559 invitations were issued. Eighty-eight percent of the participants were recruited via GP invitations, 5.4% via the PR campaign, 3% via word-of-mouth, and 2.5% via third-sector organizations. Mean recruitment cost per participant was £78.47, with an extra £26.54 per recruit paid to GPs to cover research costs.

CONCLUSIONS

REACT successfully recruited to target. Response rates were lower than initially predicted and recruitment timescales required adjustment. Written invitations from GPs were the most efficient method for recruiting older adults at risk of mobility disability. Targeted efforts could achieve more ethnically diverse cohorts. All trials should be required to provide recruitment data to enable evidence-based planning of future trials.

Attention control group activities and perceived benefit in a trial of a behavioral intervention for older adults

Researchers trialing behavioral interventions often use attention control groups, but few publish details on attention control activities or perceived benefit. Attention control groups receive the same dose of interpersonal interaction as intervention participants but no other elements of the intervention, to control for the benefits of attention that may come from behavioral interventions. Because intervention success is analyzed compared to control conditions, it is useful to examine attention control content and outcomes. The purpose of this study is to report on attention control visit activities and their perceived benefit in a randomized control trial. The trial tested an aging-in-place intervention comprised of a series of participant goal-directed visits facilitated by an occupational therapist, nurse, and handyman. The attention control group participants received visits from a lay person. We report on the number and length of visits received, types of visit activities that participants chose, and how much visit time was spent on each activity, based on the attention visitor's records. We report on participant perceptions of benefit based on a 10-item Likert-scale survey. The attention control group participants (n = 148) were cognitively intact, at least 65 years old, with at least one Instrumental Activities of Daily Living. Attention control group participants most often chose conversation (20.1% of visit time), and playing games (18.7%), as visit activities. The majority of attention control group participants (63.4%) reported "a great deal" of perceived benefit. Attention control group visits may be an appropriate comparison in studies of behavioral interventions for community-dwelling older adults.

Commentary: Engaging African Immigrants in Research Experiences and Lessons from the Field

Global migration from Africa to more economically developed regions such as the United States, Europe, the Middle East, and Australia has reached unprecedented rates in the past five decades. The size of the African immigrant population in the United States has roughly doubled every decade since 1970. However, research has not kept up with the growing size of this vulnerable population. Data from African immigrants have not traditionally been reported separately from Blacks/African Americans. There is growing interest in increasing the participation of African immigrants in research to understand their unique health needs and the full spectrum of factors impacting their health, ranging from racial, social, environmental, and behavioral factors, to individual biological and genetic factors which may also inform health challenges. This line of inquiry may also inform our understanding of health disparities among their African American counterparts. However, little is known about effective community engagement and recruitment strategies that may increase the participation of this population in research studies. The purpose of this commentary is to: 1) describe lessons learned from our experiences engaging African immigrants in research in the Baltimore, Washington, DC, and Atlanta metropolitan areas; 2) discuss strategies for successful recruitment; and 3) consider future directions of research and opportunities to translate research findings into health policy for this population.

Achieving self-management goals among low income older adults with functional limitations

Although self-management interventions can improve symptoms and disease among older adults, there is a dearth of literature on how self-management behaviors may improve factors related to the older adults' physical function. To fill this gap in the literature, we describe the patient-directed self-management goals in nursing visits that relate to physical function as part of a multi-component program. We analyze the self-management goals and outcomes of 367 low- income older adults with functional limitations who participated in the CAPABLE program: a program to reduce the health effects of impaired physical function in low-income older adults. We focus on the following self-management goals that participants chose with the nurses: pain management, depressive symptoms, incontinence, fall prevention, and communication with healthcare providers. The majority of participants chose pain (50%) or fall prevention (51%) as goals and partially or fully met their goals. Improvements across these areas may lead to improved physical function.
