An innovative approach to recruiting homebound older adults

Nurture Early for Optimal Nutrition (NEON) participatory learning and action women's groups to improve infant feeding and practices in South Asian infants: pilot randomised trial study protocol

INTRODUCTION

Feeding practices developed in early life can impact a child's nutrition, growth, dental health, cognitive development and lifetime risk of chronic diseases. Substantial evidence suggests ethnic health inequalities, and non-recommended complementary infant feeding practices among UK's South Asian (SA) population. Nurture Early for Optimal Nutrition aims to use women's group participatory learning and action (PLA) cycles to optimise infant feeding, care and dental hygiene practices in SA infants <2 years in East London.

METHODS AND ANALYSIS

A three-arm pilot feasibility cluster randomised controlled trial will assess feasibility, acceptability, costs and explore preliminary effectiveness for proposed primary outcome (ie, reporting on body mass index (BMI) z-score). Multilingual SA community facilitators will deliver the intervention, group PLA Cycle, to mothers/carers in respective ethnic/language groups. 12 wards are randomised to face-to-face PLA, online PLA and usual care arms in 1:1:1 ratio. Primary outcomes are feasibility and process measures (ie, BMI z-score, study records, feedback questionnaires, direct observation of intervention and sustainability) for assessment against Go/Stop criteria. Secondary outcomes are cluster-level and economic outcomes (ie, eating behaviour, parental feeding practices, network diffusion, children development performance, level of dental caries, general practitioner utilisation, costs, staff time). Outcomes are measured at baseline, every 2 weeks during intervention, 14 weeks and at 6 months by blinded outcome assessors where possible. This study will use concurrent mixed-methods evaluation. Quantitative analyses include descriptive summary with 95% CI and sample size calculation for the definitive trial. The intervention effect with CI will be estimated for child BMI z-score. Implementation will be evaluated qualitatively using thematic framework analysis.

ETHICS AND DISSEMINATION

Ethics approval was obtained from University College London (UCL), National Health Service (Health Research Authority (HRA) and Health and Care Research Wales (HRCW)). Results will be published in peer-reviewed journals, presented at scientific conferences/workshops with commissioners, partners and participating communities. Plain language summaries will be disseminated through community groups, websites and social media.

Recruitment of Community-Based Samples: Experiences and Recommendations for Optimizing Success

Background

Recruitment in health and social science research is a critically important but often overlooked step in conducting successful research. The challenges associated with recruitment pertain to multiple factors such as enrolling groups with vulnerabilities, obtaining geographic, cultural, and ethnic representation within study samples, supporting the participation of less accessible populations such as older adults, and developing networks to support recruitment.

Purpose

This paper presents the experiences of two early career researchers in recruiting community-based samples of older adults, their caregivers, and associated health providers.

Methods

Challenges and facilitators in recruiting two community-based qualitative research samples are identified and discussed in relation to the literature.

Results

Challenges included: identifying potential participants, engaging referral partners, implementing multi-methods, and achieving study sample diversity. Facilitators included: making connections in the community, building relationships, and drawing on existing networks.

Conclusions

Findings suggest the need for greater recognition of the importance of having clear frameworks and strategies to address recruitment prior to study commencement as well as the need to have clear outreach strategies to optimize inclusion of marginalized groups. Recommendations and a guide are provided to inform the development of recruitment approaches of early career researchers in health and social science research.

The impact of empowerment model-based education on quality of life of transgender people under hormone therapy: A randomized clinical trial

Introduction:

Gender identity disorder is a complex psychological problem and people with this disorder are at risk of many problems, including reduced quality of life. Empowerment intervention is one of the methods that can be used to improve the quality of life of people. The present study aimed to investigate the effect of empowerment model-based training on the quality of life of transgender people undergoing hormone therapy.

Methods:

The present study is a randomized clinical trial that was conducted in 2012 on 81 transgender people at Tehran Welfare Center. The study samples were randomly assigned into two groups of intervention and control. The intervention group received training based on the empowerment model (threat perception, problem-solving, educational participation, and evaluation) and the control group received routine treatment.

Results:

According to the findings, after the intervention, a statistically significant difference was found between the two groups in terms of the mean level of overt anxiety (P = 0.045) and aspects of emotional health (P = 0.030), the general perception of health (P = 0.007), mental health (P = 0.008), and overall quality of life (P = 0.005). Also, although there was a statistically significant difference in the aspect emotional well-being in the intervention group before and after the intervention (P = 0.034), this difference was not significant between the two groups (P = 0.274).

Conclusion:

The results showed that the empowerment-based training program had a significant relationship with the improvement in aspects of emotional health, the overall perception of health, mental health, emotional well-being and overall quality of life.

Willingness to Participate in Vaccine-Related Clinical Trials among Older Adults

The purpose of this study is to understand among a convenience sample of 400 adults aged 60 years of age or older (1) reasons for being willing or unwilling to participate in a vaccine clinical research study and (2) overall perceptions about vaccine clinical research. A cross-sectional study using a sample of older adults residing in the metro-Atlanta area and surrounding neighborhoods was conducted. The study questionnaire contained 37 questions, including questions about socio-demographics and perceptions about clinical trial processes. Statistical analysis was conducted using logistic regression. The adjusted modeling results indicated that sex, distance to research clinic, and being informed about the research findings played a role in the likelihood of an elderly person participating in a vaccine study. Males were more likely to participate in clinical trials as compared to females (OR: 2.486; CI: 1.042–5.934). Most participants were willing to travel up to 25 miles from the research clinic. Of the respondents, 45% were unlikely to participate if the results of the current trial are not shared. Improving access to clinical trials in terms of distance traveled and ensuring streamlined processes to inform participants about the results of the trial in the future would increase willingness to participate in vaccine clinical trials. The survey could serve as a useful tool for conducting vaccine studies and other clinical trials by understanding the barriers specific to the elderly.

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

The CAPABLE (Community Aging in Place, Advancing Better Living for Elders) trial in Baltimore City tested whether an interdisciplinary team of occupational therapists, nurses, and handymen reduces disability and health expenditures in community-dwelling older adults with functional difficulties. This study describes methods and associated costs of recruiting 300 low-income, cognitively intact, older adults with functional difficulties into this study. Sources of participant enrollment included direct mailings (35%), government program referrals (19%), community-based organizations (16%), ambassador referrals (15%), and media (4%). Fifty six (30%) of 187 older adults referred through government organizations were enrolled, while 49 (7.6%) of 648 referred from community-based organizations were enrolled. Total recruitment costs were US$81,453.12. Costs per participant for mailings, media, ambassadors, and community-based organizations were respectively US$745.10, US$256.82, US$22.28, and US$1.00. Direct mailings yielded the most participants but was the most costly method per participant. Ambassadors were least expensive and may offer a low-cost addition to community outreach for recruitment of older adults into research.

Evidence for strategies that improve recruitment and retention of adults aged 65 years and over in randomised trials and observational studies: a systematic review

Background

adults aged ≥65 years are often excluded from health research studies. Lack of representation reduces generalisability of treatments for this age group.

Objective

to evaluate the effectiveness of strategies that improve recruitment and retention of adults aged ≥65 in observational studies and randomised controlled trials (RCTs).

Methods

searches conducted in 10 databases for RCTs of recruitment and retention strategies in RCTs or observational studies. Two reviewers screened abstracts and full-text articles for eligibility and extracted data. Studies without separate data for adults aged ≥65 were discarded. Risk of bias assessed using the Cochrane Risk of Bias tool. Results were synthesised narratively.

Results

thirty-two studies were included in the review (n = 75,444). Twelve studies had low risk of bias, of which 10 had successful strategies including: Opt-out versus opt-in increased recruitment (13.6% (n = 261)-18.7% (n = 36) difference; two studies); Advance notification increased retention (1.6% difference, OR 1.45; 95% CI 1.01, 2.10, one study (n = 2,686); 9.1% difference at 4 months, 1.44; 1.08, 1.92, one study (n = 753)); Hand-delivered versus postal surveys increased response (25.1% difference; X2 = 11.40, P < 0.01; one study (n = 139)); Open randomised design versus blinded RCT increased recruitment (1.56; 1.05, 2.33) and retention (13.9% difference; 3.1%, 24.6%) in one study (n = 538). Risk of bias was high/unclear for studies in which incentives or shorter length questionnaires increased response.

Discussion

in low risk of bias studies, few of the strategies that improved participation in older adults had been tested in ≥1 study. Opt-out and advance notification strategies improved recruitment and retention, respectively, although an opt-out approach may have ethical limitations. Evidence from single studies limits the generalisability of other strategies.

Recruiting Participants into Pilot Trials: Techniques for Researchers with Shoestring Budgets

Limited research has focused on recruitment strategies for health promotion researchers conducting small-scale pilot studies. Such research is important because small studies often have limited funding streams and personnel resources. Accordingly, many techniques implemented by large-scale studies are of limited use to smaller research projects. This article provides an overview effective participant recruitment techniques for pilot studies with limited funds and personnel resources. Recruitment techniques were derived from the first author's experience in recruiting participants during his doctoral and postdoctoral studies, the over 25 years of research experience of each of the co-authors, and an extensive review of the literature. Five key recruitment techniques are discussed: 1) leverage existing social networks and personal contacts, 2) identify and foster collaborations with community gatekeepers, 3) develop a comprehensive list of potential recruitment platforms and venues, 4) create recruitment materials that succinctly describe the purpose of the study, and 5) build respectful and trusting relationships with potential participants. Implementation of the proposed techniques can lead to enhanced recruitment, as well as retention among study participants.

The effect of out-of-home activity intervention delivered by volunteers on depressive symptoms among older people with severe mobility limitations: a randomized controlled trial

OBJECTIVES

To examine the effects of an individualized outdoor activity intervention carried out by volunteers on depressive symptoms among community-living older people with severe mobility limitations who have difficulties accessing the outdoors independently.

METHODS

Secondary analyses of the 'Volunteering, Access to Outdoor Activities and Wellbeing in Older People' (VOW) data (ISRCTN56847832). VOW was a randomized single blinded two-arm controlled trial conducted in Jyväskylä, Finland, in 2009-2011. At baseline, 121 people aged 67-92 years with severe mobility limitations were interviewed at home and randomized into either an intervention or waiting list control group. Volunteers (n = 47) had retired from regular work and were trained for the study. A volunteer assisted the participant in attending recreational out-of-home activities once a week for three months. Depressive symptoms were assessed using the Center for the Epidemiological Studies Depression Scale (CES-D).

RESULTS

In the intervention group the CES-D score did not change during the intervention (from 15.1 ± standard error 0.9 to 15.1 ± 0.9), while in the control group it increased from 17.0 ± 1.3 to 19.1 ± 1.4 (intervention effect p = .096). Among the subgroups with minor depressive symptoms at baseline (CES-D score 16-20), the CES-D score decreased in the intervention group and increased in the control group (p = .025).

CONCLUSION

A three-month outdoor activity intervention may improve mood among older people with severe mobility limitations. More randomized controlled trials of the topic are needed.

Exploring gender, age, time and space in research with older Pakistani Muslims in the United Kingdom: formalised research 'ethics' and performances of the public/private divide in 'the field'

In recent years, there has been an increasing interest in researching ageing ethnic minority populations in the West. However, older people from such minority communities have received comparatively little attention in wide-ranging discussions on appropriate research methodologies. By a process of critically reflecting on our experiences of undertaking fieldwork for our Economic and Social Research Council New Dynamics of Ageing study of ‘Families and Caring in South Asian Communities', this paper maps out the key methodological and ethical challenges we faced and, in the process, highlights the importance of developing socially appropriate research methodologies and ethical frameworks for research with such populations. With a reflexive approach, we specifically explore the significance of gender, age, time and space to the fieldwork processes and the ‘field’ relationships formed at various stages of the research process. In particular, we explore three key emergent issues which conflicted with our formal research protocols and presented particular challenges for us and our older Pakistani Muslim participants: (a) structuring of time in daily life; (b) gendered use of public and private spaces; and (c) orality of informal social contexts and relationships. Using illustrations from our fieldwork which reveal the particular significance of these issues to our fieldwork experiences and performativities of public/private identities, we highlight important tensions between formalised ethical and methodological dimensions of conducting funded research and the realities of being in ‘the field’. We conclude the paper by emphasising the need to explore further not only the ways in which researchers can adopt more socially and culturally sensitive data collection processes and methodologies at the micro level of their interactions with research participants, but also contextualising the particular challenges experienced by researchers and their participants in terms of the wider research frameworks and agendas as well as the broader social contexts within which they live and work.

Recruiting older people at nutritional risk for clinical trials: what have we learned?

Background

The difficulty of recruiting older people to clinical trials is well described, but there is limited information about effective ways to screen and recruit older people into trials, and the reasons for their reluctance to enrol. This paper examines recruitment efforts for a community-based health intervention study that targeted older adults.

Methods

One year randomized control trial. Undernourished men and women, aged ≥ 65 years and living independently in the community were recruited in three Australian states. Participants were allocated to either oral testosterone undecanoate and high calorie oral nutritional supplement or placebo medication and low calorie oral nutritional supplementation. Hospital admissions, functional status, nutritional health, muscle strength, and other variables were assessed.

Results

4023 potential participants were identified and 767 were screened by a variety of methods: hospital note screening, referrals from geriatric health services, advertising and media segments/appearances. 53 participants (7% of total screened) were recruited. The majority of potentially eligible participants declined participation in the trial after reading the information sheet. Media was the more successful method of recruiting, whereas contacting people identified by screening a large number of hospital records was not successful in recruiting any participants.

Conclusion

Recruitment of frail and older participants is difficult and multiple strategies are required to facilitate participation.

Improving the Cooperation Rate of Older Adults and Their Caregivers in Research Surveys

BACKGROUND

Recruiting older adults, their family members and their home care workers as participants in research studies is particularly complicated. This might be due to medical or cognitive problems of the older adult as well as the high workload and shortage of time experienced by caregivers. The present study compared the contribution of two different versions of an advanced letter followed by two different versions of a recruitment phone call to the cooperation rate of older adults, family caregivers and home care workers in a face-to-face survey.

METHODS

A quasi-experimental design was used to compare the contribution of the different types of appeal. A total of 2,014 caregiving units (composed of an older adult, a family member and a home care worker) were randomly sampled from a list of Israeli long-term care insurance beneficiaries. 74.32% of the sampled caregiving units were eligible to participate in the study. The first group of participants received formal and succinctly phrased written and oral appeals - an advanced letter followed by a recruitment phone call. The second group of participants received the original formal and succinctly phrased advanced letter, but a revised recruitment phone call that included a more personal approach, the provision of broader information about the study and the avoidance of words with a possible negative connotation. The third group of participants received both a revised advanced letter and a revised recruitment phone call.

RESULTS

Using the succinctly phrased written and oral appeals, we had a cooperation rate of about 50% for the entire caregiving unit. Using a revised advanced letter and a revised recruitment phone call yielded an increase of 20-25% in the cooperation rate for the entire caregiving unit. Using the revised recruitment phone call and the original advanced letter yielded an increase in the cooperation rate only among migrant home care workers.

CONCLUSION

This study showed that by changing the format of appeal we can increase the cooperation rate of older adults and their caregivers in a research survey. This study also pointed out the importance of the advanced letter.

A chronic grief intervention for dementia family caregivers in long-term care

Dementia caregivers do not relinquish their role after placing family members in long-term care and they experience increased chronic grief. The Chronic Grief Management Intervention (CGMI) is a12-week group-based program that uses guided discussion to deliver knowledge of Alzheimer's or a related dementia and teach skills in communication, conflict resolution, and chronic grief management in dementia caregivers who placed their family members in long-term care. Using a quasi-experimental design, 83 caregivers from 15 long-term care facilities received either the CGMI (n = 34) or a comparison condition consisting of two check-in calls (n = 49). In this pilot study, we examined the feasibility of implementing the CGMI and evaluated the effects of the intervention on caregivers' knowledge and skill and their chronic grief and depression. The intervention was feasible and resulted in significant improvement in caregivers' heartfelt sadness and longing at 3 months and a significant drop in their guilt at the 6-month follow-up.

Nurse-led health promotion interventions improve quality of life in frail older home care clients: lessons learned from three randomized trials in Ontario, Canada

OBJECTIVE

This paper explores the lessons learned from a series of three randomized controlled trials that included 498 community-living frail older adults (≥65 years) using home care services in Southern Ontario, Canada. Each study was designed to evaluate the effectiveness of different multi-component nurse-led health promotion and disease prevention (HPDP) interventions.

METHODS

The nurse-led HPDP interventions were 6- or 12-month multi-component and evidence-based strategies targeting known risk factors for functional decline and frailty. Across the three studies, a common approach was used to measure the change in health-related quality of life (HRQOL) (SF-36) and the costs of use of health services (Health and Social Services Utilization Inventory) from baseline to the end of the intervention.

RESULTS

The main lesson learned from the three studies is that nurse-led HPDP interventions for frail older home care clients provide greater improvements in HRQOL compared with usual home care. Such approaches are highly acceptable to this population and can be implemented using existing home care resources. Nurse-led HPDP interventions should include multiple home visits, multidimensional screening and assessment, multi-component evidence-based HPDP strategies, intensive case management, inter-professional collaboration, providers with geriatric training and experience, referral to and coordination of community services, and theory use.

CONCLUSION

The results of the three trials underscore the need to reinvest in nurse-led HPDP interventions in home care to optimize HRQOL and promote ageing in place in the target population of frail older adults. More studies are needed to evaluate the effectiveness of additional nurse-led HPDP interventions in other contexts and settings.

Recruitment of Older Adults: Success May Be in the Details

PURPOSE

Describe recruitment strategies used in a randomized clinical trial of a behavioral prospective memory intervention to improve medication adherence for older adults taking antihypertensive medication.

RESULTS

Recruitment strategies represent 4 themes: accessing an appropriate population, communication and trust-building, providing comfort and security, and expressing gratitude. Recruitment activities resulted in 276 participants with a mean age of 76.32 years, and study enrollment included 207 women, 69 men, and 54 persons representing ethnic minorities. Recruitment success was linked to cultivating relationships with community-based organizations, face-to-face contact with potential study participants, and providing service (e.g., blood pressure checks) as an access point to eligible participants. Seventy-two percent of potential participants who completed a follow-up call and met eligibility criteria were enrolled in the study. The attrition rate was 14.34%.

IMPLICATIONS

The projected increase in the number of older adults intensifies the need to study interventions that improve health outcomes. The challenge is to recruit sufficient numbers of participants who are also representative of older adults to test these interventions. Failing to recruit a sufficient and representative sample can compromise statistical power and the generalizability of study findings.

Older people's preferences regarding programme formats for managing concerns about falls

OBJECTIVE

to explore the preferences of community-dwelling older persons regarding different programme formats for managing concerns about falls.

SUBJECTS AND DESIGN

cross-sectional study of 5,755 community-dwelling people aged ≥ 70 years in the Netherlands.

METHODS

a questionnaire assessed people's willingness to participate per programme format (n=6), i.e. a programme at home, via telephone, via home visits and telephone consultations, via television or via Internet.

RESULTS

of the 2,498 responders, 62.7% indicated no interest in any of the formats. The willingness to participate per programme format varied between 21.5 (at home) and 9.4% (via Internet). Among people interested in at least one of the formats (n=931), higher levels of fall-related concerns were associated with increased preference for a programme with home visits. Poor perceived health and age ≥ 80 years were associated with less preference for a group programme. Higher educated people were more in favour of a programme via Internet compared with their lower educated counterparts.

CONCLUSION

the majority of community-dwelling older people are not likely to participate in any of the six proposed programme formats for managing concerns about falls. However, when diverse formats of effective programmes will be made available, uptake and adherence may be increased since programme preferences are associated to specific population characteristics.

Randomized control trial of the Health Empowerment Intervention: feasibility and impact

BACKGROUND

Older adults prefer to stay in their homes for as long as possible but are often unaware of the resources in their community to help them to remain in their home. Access to resources may be important among older adults, representing a critical area for intervention.

OBJECTIVES

The study aim was to evaluate the feasibility of the Health Empowerment Intervention (HEI) and to explore the impact of the HEI on the theoretical mediating variables of health empowerment and purposeful participation in goal attainment and the outcome variable of well-being with homebound older adults.

METHOD

Fifty-nine eligible homebound older adults were randomly assigned to the intervention group or the comparison group. The HEI consisted of 6 weekly visits, whereas the comparison group received a weekly newsletter for 6 weeks. Participants were measured at baseline, after the 6-week protocol, and at 12 weeks. Data were analyzed using descriptive statistics, t test, chi, and analysis of covariance.

RESULTS

There was a significant difference between groups in education. The participants in the intervention found the sessions to be helpful in recognizing resources. In addition, participants in the intervention group had significantly higher scores in the mediator purposeful participation in goal attainment, F(2, 83) = 3.71, p = .03. There was no significant main effect for the mediator health empowerment; however, the intervention group increased in the subscale personal growth from baseline to 12 weeks, F(1, 83) = 3.88, p = .05.

DISCUSSION

This randomized control trial provided initial support for the hypothesis that homebound older adults receiving the HEI would find the intervention acceptable and have significantly improved health empowerment, purposeful participation in goal attainment, and well-being than an attentional comparison group receiving a weekly newsletter.
