Recruiting vulnerable populations into research: a systematic review of recruitment interventions

Using Social Media to Engage and Enroll Underrepresented Populations: Longitudinal Digital Health Research

BACKGROUND

Emerging digital health research poses roadblocks to the inclusion of historically marginalized populations in research. Exclusion of underresourced communities in digital health research is a result of multiple factors (eg, limited technology access, decreased digital literacy, language barriers, and historical mistrust of research and research institutions). Alternative methods of access and engagement may aid in achieving long-term sustainability of diversified participation in digital health research, ensuring that developed technologies and research outcomes are effective and equitable.

OBJECTIVE

This study aims to (1) characterize socioeconomic and demographic differences in individuals who enrolled and engaged with different remote, digital, and traditional recruitment methods in a digital health pregnancy study and (2) determine whether social media outreach is an efficient way of recruiting and retaining specific underrepresented populations (URPs) in digital health research.

METHODS

The Better Understanding the Metamorphosis of Pregnancy (BUMP) study was used as a case example. This is a prospective, observational, cohort study using digital health technology to increase understanding of pregnancy among 524 women, aged 18-40 years, in the United States. The study used different recruitment strategies: patient portal for genetic testing results, paid/unpaid social media ads, and a community health organization providing care to pregnant women (Moses/Weitzman Health System).

RESULTS

Social media as a recruitment tool to engage URPs in a digital health study was overall effective, with a 23.6% (140/594) enrollment rate of those completing study interest forms across 25 weeks. Community-based partnerships were less successful, however, resulting in 53.3% (57/107) engagement with recruitment material and only 8.8% (5/57) ultimately enrolling in the study. Paid social media ads provided access to and enrollment of a diverse potential participant pool of race- or ethnicity-based URPs in comparison to other digital recruitment channels. Of those that engaged with study materials, paid recruitment had the highest percentage of non-White (non-Hispanic) respondents (85/321, 26.5%), in comparison to unpaid ads (Facebook and Reddit; 37/167, 22.2%). Of the enrolled participants, paid ads also had the highest percentage of non-White (non-Hispanic) participants (14/70, 20%), compared to unpaid ads (8/52, 15.4%) and genetic testing service subscribers (72/384, 18.8%). Recruitment completed via paid ads (Instagram) had the highest study retention rate (52/70, 74.3%) across outreach methods, whereas recruitment via community-based partnerships had the lowest (2/5, 40%). Retention of non-White (non-Hispanic) participants was low across recruitment methods: paid (8/52, 15.4%), unpaid (3/35, 14.3%), and genetic testing service subscribers (50/281, 17.8%).

CONCLUSIONS

Social media recruitment (paid/unpaid) provides access to URPs and facilitates sustained retention similar to other methods, but with varying strengths and weaknesses. URPs showed lower retention rates than their White counterparts across outreach methods. Community-based recruitment showed lower engagement, enrollment, and retention. These findings highlight social media's potential for URP engagement and enrollment, illuminate potential roadblocks of traditional methods, and underscore the need for tailored research to improve URP enrollment and retention.

Augmenting Insufficiently Accruing Oncology Clinical Trials Using Generative Models: Validation Study

BACKGROUND

Insufficient patient accrual is a major challenge in clinical trials and can result in underpowered studies, as well as exposing study participants to toxicity and additional costs, with limited scientific benefit. Real-world data can provide external controls, but insufficient accrual affects all arms of a study, not just controls. Studies that used generative models to simulate more patients were limited in the accrual scenarios considered, replicability criteria, number of generative models, and number of clinical trials evaluated.

OBJECTIVE

This study aimed to perform a comprehensive evaluation on the extent generative models can be used to simulate additional patients to compensate for insufficient accrual in clinical trials.

METHODS

We performed a retrospective analysis using 10 datasets from 9 fully accrued, completed, and published cancer trials. For each trial, we removed the latest recruited patients (from 10% to 50%), trained a generative model on the remaining patients, and simulated additional patients to replace the removed ones using the generative model to augment the available data. We then replicated the published analysis on this augmented dataset to determine if the findings remained the same. Four different generative models were evaluated: sequential synthesis with decision trees, Bayesian network, generative adversarial network, and a variational autoencoder. These generative models were compared to sampling with replacement (ie, bootstrap) as a simple alternative. Replication of the published analyses used 4 metrics: decision agreement, estimate agreement, standardized difference, and CI overlap.

RESULTS

Sequential synthesis performed well on the 4 replication metrics for the removal of up to 40% of the last recruited patients (decision agreement: 88% to 100% across datasets, estimate agreement: 100%, cannot reject standardized difference null hypothesis: 100%, and CI overlap: 0.8-0.92). Sampling with replacement was the next most effective approach, with decision agreement varying from 78% to 89% across all datasets. There was no evidence of a monotonic relationship in the estimated effect size with recruitment order across these studies. This suggests that patients recruited earlier in a trial were not systematically different than those recruited later, at least partially explaining why generative models trained on early data can effectively simulate patients recruited later in a trial. The fidelity of the generated data relative to the training data on the Hellinger distance was high in all cases.

CONCLUSIONS

For an oncology study with insufficient accrual with as few as 60% of target recruitment, sequential synthesis can enable the simulation of the full dataset had the study continued accruing patients and can be an alternative to drawing conclusions from an underpowered study. These results provide evidence demonstrating the potential for generative models to rescue poorly accruing clinical trials, but additional studies are needed to confirm these findings and to generalize them for other diseases.

Incorporating health literacy principles into the adaptation of a methods motivational interviewing approach for enrolling black adults in a pilot randomized trial

Suboptimal enrollment and retention efforts can compromise the quality of clinical trials. Barriers to enrolling marginalized populations include low awareness/education about clinical trials. Methods-Motivational Interviewing (MMI) is a patient-centered process that integrates education in providing trial information and engages participants in discussions about the trial before enrollment. Though the MMI approach is effective in enhancing trial recruitment and retention, limited studies have incorporated evidence-based health literacy approaches, especially for underrepresented individuals. In this study, prior to the informed consent process, Black adults completed an interactive orientation followed by a small group discussion. The content used health literacy principles including plain language, infographics, and a pictorial roadmap to guide participants about the purpose of a trial, the randomization process, the study objectives, and timeline. Thereafter, two focus groups explored participants' perceptions of the enrollment process. Fifteen participants attended the orientation with 14 enrolled in the trial after the orientation, (93% enrollment rate). Retention was 93% (control) to 100% (intervention) at the end of 6 months. Participants reported positive orientation experiences due to a better understanding of the study information, expectations, and rationale behind randomization. Implementing an adapted MMI approach focused on health literacy principles may improve trial enrollment and retention rates among Black adults.

Racial/Ethnic Disparities in Oncology Clinical Trial Participation: Investigator Attitudes, Needs, and Motivation to Improve

PURPOSE

The perspective of all stakeholders involved in clinical trials is critical to addressing disparities in racial/ethnic minority (REM) clinical trial participation. Little is known about clinical trial investigator perspectives. To our knowledge, there are no published studies assessing differences in investigator perspectives on the basis of their primary role in clinical trials (ie, principal investigator [PI] or subinvestigator [sub-I]). Differences likely exist in investigator perspectives on the basis of having a more design-oriented (PI) or recruitment-oriented (sub-I) role.

MATERIALS AND METHODS

We conducted a cross-sectional, anonymous, pilot survey of 107 oncology clinical trial investigators at an academic center. The survey assessed five domains about disparities in REM clinical trial participation. We performed a subgroup analysis of mid- and late-career investigators (≥10 years of experience) comparing PIs (opened ≥one clinical trial in the past year) with sub-Is (did not).

RESULTS

Among 60 respondents, a majority (83%) strongly agreed disparities exist in REM clinical trial participation and that this is problematic (75%). Notably, 45% agreed they cannot directly address this problem. In the subgroup analysis, PIs were more likely to have received training about barriers/facilitators to REM clinical trial participation and strategies to increase participation. They were also more likely to endorse wanting help in this area.

CONCLUSION

Our results suggest clinical trial investigators are aware of disparities in REM clinical trial participation but do not feel they can address them. PIs are more likely to have received previous training on this topic and to want help to improve their ability to address disparities. More studies are needed to inform targeted interventions and structural improvements to enhance investigators' self-efficacy for improving REM participation in oncology clinical trials.

Recruitment and retention strategies to promote research engagement among caregivers and their children: A scoping review

Long-term health and developmental impact after in utero opioid and other substance exposures is unclear. There is an urgent need for well-designed, prospective, long-term observational studies. The HEALthy Brain and Child Development Study aims to address this need. It will require optimizing recruitment and retention of caregivers and young children in long-term research. Therefore, a scoping review of original research articles, indexed in the PubMed database and published in English between January 1, 2010, and November 23, 2023, was conducted on recruitment and retention strategies of caregiver-child (≤6 years old) dyads in observational, cohort studies. Among 2,902 titles/abstracts reviewed, 37 articles were found eligible. Of those, 29 (78%) addressed recruitment, and 18 (49%) addressed retention. Thirty-four (92%) articles focused on strategies for facilitating recruitment and/or retention, while 18 (49%) described potentially harmful approaches. Recruitment and retention facilitators included face-to-face and regular contact, establishing a relationship with study personnel, use of technology and social platforms, minimizing inconveniences, and promoting incentives. This review demonstrates that numerous factors can affect engagement of caregivers and their children in long-term cohort studies. Better understanding of these factors can inform researchers about optimal approaches to recruitment and retention of caregiver-child dyads in longitudinal research.

Social marketing and the challenges of participant recruitment

Recruitment of research participants often has not obtained a desired sample size, thereby becoming a major problem inhibiting investigators' ability to adequately test the specified hypotheses. Social marketing with its four Ps, originally developed by the business world to sell products and adapted for public health initiatives, is proposed as a dynamic comprehensive conceptual framework to apply marketing principles and practices to enhance participant recruitment. Applying a social marketing approach to research recruitment would require initial investigation to understand the motivations of the target audience in regard to research participation, and continued research throughout the main project to adapt the recruitment efforts as limitations arise. Additional funding would be needed for successful social marketing research recruitment programs to be systematically implemented and evaluated as part of research projects. In this paper, we define social marketing concepts, briefly review the available literature supporting social marketing applied to recruitment for research studies, and consider ethical issues that may arise when using a social marketing approach.

A Systematic Review of Recruiting and Retaining Sociodemographically Diverse Families in Neurodevelopmental Research Studies

Underrepresentation of socioeconomically, culturally, and/or linguistically diverse (SCLD) children with neurodevelopmental disorders (NDD) and their families has become a focal point for researchers. This systematic review aimed to identify researchers' strategies for recruiting and retaining SCLD families of children with NDD, published between 1993 and 2018. One hundred twenty-six articles were included, and study samples were categorized as "High SCLD" and "Low SCLD". Chi-square tests of independence were used to determine associations between sample composition (i.e., High/Low SCLD sample) and study characteristics reported. Significant associations were found between sample composition and studies that explicitly stated intention to recruit SCLD families, χ2(1) = 12.70, p < .001, Phi = 0.38 (moderate); and for studies that reported the following participant characteristics: language, χ2(1) = 29.58, p < .001, Phi = 0.48 (moderate-to-large); and race/ethnicity + SES + language, χ2(1) = 19.26, p <. 001, Phi = 0.39 (moderate). However, associations were not found between recruitment and retention approaches and whether studies included High SCLD or Low SCLD samples. Further study of NDD researchers' recruitment and retention approaches that successfully include SCLD families is needed.

A community health worker led approach to cardiovascular disease prevention in the UK-SPICES-Sussex (scaling-up packages of interventions for cardiovascular disease prevention in selected sites in Europe and Sub-saharan Africa): an implementation research project

Background

This paper describes a UK-based study, SPICES-Sussex, which aimed to co-produce and implement a community-based cardiovascular disease (CVD) risk assessment and reduction intervention to support under-served populations at moderate risk of CVD. The objectives were to enhance stakeholder engagement; to implement the intervention in four research sites and to evaluate the use of Voluntary and Community and Social Enterprises (VCSE) and Community Health Worker (CHW) partnerships in health interventions.

Methods

A type three hybrid implementation study design was used with mixed methods data. This paper represents the process evaluation of the implementation of the SPICES-Sussex Project. The evaluation was conducted using the RE-AIM framework.

Results

Reach: 381 individuals took part in the risk profiling questionnaire and forty-one women, and five men participated in the coaching intervention. Effectiveness: quantitative results from intervention participants showed significant improvements in CVD behavioural risk factors across several measures. Qualitative data indicated high acceptability, with the holistic, personalised, and person-centred approach being valued by participants. Adoption: 50% of VCSEs approached took part in the SPICES programme, The CHWs felt empowered to deliver high-quality and mutually beneficial coaching within a strong project infrastructure that made use of VCSE partnerships. Implementation: Co-design meetings resulted in local adaptations being made to the intervention. 29 (63%) of participants completed the intervention. Practical issues concerned how to embed CHWs in a health service context, how to keep engaging participants, and tensions between research integrity and the needs and expectations of those in the voluntary sector. Maintenance: Several VCSEs expressed an interest in continuing the intervention after the end of the SPICES programme.

Conclusion

Community-engagement approaches have the potential to have positively impact the health and wellbeing of certain groups. Furthermore, VCSEs and CHWs represent a significant untapped resource in the UK. However, more work needs to be done to understand how links between the sectors can be bridged to deliver evidence-based effective alternative preventative healthcare. Reaching vulnerable populations remains a challenge despite partnerships with VCSEs which are embedded in the community. By showing what went well and what did not, this project can guide future work in community engagement for health.

Effective interventions to increase representation of under-served groups in randomised trials in UK and Ireland: a scoping literature review

Background

Participants in clinical trials often do not reflect the populations that could benefit from the treatments being investigated. There are known barriers to trial participation for under-served groups, but limited evidence on strategies to alleviate these barriers to improve representation. This scoping review aimed to identify effective interventions and design features that improve the representation `of under-served groups in trials, focusing on the UK and Ireland.

Methods

We included methodological research studies that reported interventions to improve representation of ethnic minority groups, socioeconomically disadvantaged groups, older people, or those with impaired capacity to consent to randomised controlled trials, conducted in the UK and Ireland, published between 2000-2021. Systematic searches were conducted in November 2021 and data were independently extracted by two authors and narratively synthesised.

Results

Seven studies were included: one randomised controlled study embedded in five trials, one mixed-methods study, and five studies reporting 'lessons learnt' from one trial. We categorised the 47 reported interventions or strategies into nine broad themes: Recruitment sites, recruitment settings, community engagement, and communication with participants, incentives, inclusion criteria, flexibility, patient documentation, and the consent process. Only 28/47 interventions were evaluated, 23 of which were comparison of recruitment pathways.The randomised study found that a £100 incentive mentioned in the invitation letter increased positive responses overall across drug trials in cardiovascular disease and hypertension, but not for older people or those living in the most deprived areas. Invitation letters via GPs and working with communities were reported as successful recruitment pathways in recruiting different under-served populations.

Conclusions

Interventions aiming to improve the recruitment of under-served groups in the UK and Ireland were reported across seven papers, but their effectiveness was rarely rigorously evaluated. Included studies were context specific. Using a variety of recruitment methods is likely to help achieve a more diverse cohort.

Factors related to willingness to participate in biomedical research on neglected tropical diseases: A systematic review

BACKGROUND

Understanding the barriers to and facilitators of participation in research could enhance recruitment rates for biomedical research on Neglected Tropical Diseases (NTDs) and help to avoid the problems associated with poor recruitment.

METHODOLOGY/PRINCIPAL FINDINGS

We conducted a systematic review to identify factors related to willingness to participate in biomedical research on Neglected Tropical Diseases (NTDs). Our search included the following databases: Medline/PubMed, Embase (Embase.com), Global Index Medicus (WHO), Web of Science (Core collection), and gray literature. We included studies that analyzed or reported factors associated with willingness to participate in NTD research, using either quantitative methods (such as clinical trials, cohorts, and cross-sectional studies) or qualitative methods (such as focus group discussions, semi-structured interviews, and in-depth interviews). There were no language restrictions, but we excluded review articles, notes, case reports, letters to the editor, editor's notes, extended abstracts, proceedings, patents, editorials, and other editorial materials. Screening of citations, data extraction, and risk of bias assessment was conducted by independent reviewers, according to the study protocol registered on PROSPERO. For analyses, we assessed the frequency of barriers, enablers, and the frequency of recruitment interventions mentioned in the included studies. The protocol for this systematic review was registered under registration number CRD42020212536. (S1 Appendix) We identified 2070 citations, 1470 from the databases, and 600 from other sources. From those, eleven studies were selected for data extraction and analysis. The studies were conducted in Africa, Asia, and North America. Personal health benefits, monetary benefits, and community engagement and sensitization strategies were identified as the main reasons for participating in biomedical research on Neglected Tropical Diseases (NTDs). However, distrust in researchers, lack of knowledge about research methods among potential participants, and previous negative experiences were identified as the main barriers to participating in biomedical research on NTDs.

CONCLUSIONS/SIGNIFICANCE

This systematic review provides recommendations for improving adherence to biomedical research on Neglected Tropical Diseases, which can be applied in practice.

Equity Concerns Across Pediatric Research Recruitment: An Analysis of Research Staff Interviews

BACKGROUND AND OBJECTIVES

Difficulty recruiting individuals from minoritized and underserved populations for clinical research is well documented and has health equity implications. Previously, we reported findings from interviews with research staff about pediatric research recruitment processes. Respondents raised equity concerns related to recruitment and enrollment of participants from minoritized, low resourced, and underserved populations. We therefore decided to perform a secondary coding of the transcripts to examine equity-related issues systematically.

METHODS

We conducted a process of secondary coding and analysis of interviews with research staff involved in recruitment for pediatric clinical research. Through consensus we identified codes relevant to equity and developed a conceptual framework including 5 stages of research.

RESULTS

We analyzed 28 interviews and coded equity-related items. We report 6 implications of our findings. First, inequitable access to clinical care is an upstream barrier to research participation. Second, there is a need to increase research opportunities where underserved and under-represented populations receive care. Third, increasing research team diversity can build trust with patients and families, but teams must ensure adequate support of all research team members. Fourth, issues related to consent processes raise institutional-level opportunities for improvement. Fifth, there are numerous study procedure-related barriers to participation. Sixth, our analysis illustrates that individuals who speak languages other than English face barriers across multiple stages.

CONCLUSIONS

Research staff members identified equity-related concerns and recommended potential solutions across 5 stages of the research process, which may guide those endeavoring to improve research recruitment for pediatric patients from minoritized and underserved populations.

The power of language: how to bridge the gap between healthcare research and patients - a scoping review

OBJECTIVE

The value of patient involvement to the design, conduct, and outcomes of healthcare research is increasingly being recognized. Patient involvement also provides greater patient accessibility and contribution to research. However, the use of inaccessible and technical language when communicating with patients is a barrier to effective patient involvement.

METHODS

We analyzed peer-reviewed and gray literature on how language is used in communication between healthcare researchers and patients. We used this analysis to generate a set of recommendations for healthcare researchers about using more inclusive and accessible language when involving patients in research. This scoping review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Review (PRISMA-ScR) checklist.

RESULTS

Four major themes about the use of language were developed from the literature analysis and were used to develop the set of recommendations. These recommendations include guidance on using standardized terminology and plain language when involving patients in healthcare research. They also discuss the implementation of co-development practices, patient support initiatives, and researcher training, as well as ways to improve emotional awareness and the need for greater equality, diversity, and inclusion.

DISCUSSION AND CONCLUSION

The use of inclusive, empathetic, and clear language can encourage patients to be involved in research and, once they are involved, make them feel like equal, empowered, and valued partners. Working toward developing processes and guidelines for the use of language that enables an equal partnership between researchers and patients is critical.

Merits and Pitfalls of Social Media as a Platform for Recruitment of Study Participants

Efficient and effective methods of recruiting participants for studies have characteristically come with many challenges. The unprecedented rise of social media platforms such as Facebook and Instagram has revolutionized the ease of recruiting participants as compared to more traditional methods such as newspaper or radio advertisements. While these new advancements may seem to increase the success of recruitment, they are not without their own faults and limitations. In this paper, we intend to dissect the advantages and disadvantages of social media platforms in recruiting participants. Specifically, we will discuss the advantages of targeted and rapid recruitment, engagement, and cost reduction as well as the disadvantages of representativeness, privacy concerns, limited control, and limited access.

Recruitment and Retention Strategies for Underrepresented Populations and Adults With Arthritis in Behavioral Interventions: A Scoping Review

OBJECTIVE

To identify strategies used to recruit and retain underrepresented populations and populations with arthritis or fibromyalgia (FM) into behavioral programs targeting exercise, physical activity, or chronic disease self management.

METHODS

Five bibliographic databases were searched for articles published between January 2000 and May 2022. The search focused on strategies and best practices for recruiting and retaining underrepresented populations or populations with arthritis or FM into disease self-management or physical activity/exercise programs. Abstracts and full-text articles were screened for inclusion by 2 independent reviewers, and 2 reviewers extracted data from included articles.

RESULTS

Of the 2,800 articles, a total of 43 publications (31 interventions, 8 reviews, 4 qualitative/descriptive studies) met criteria and were included. The majority of studies focused on physical activity/exercise (n = 36) and targeted African American (n = 17), Hispanic (n = 9), or arthritis populations (n = 7). Recruitment strategies that were frequently used included having race- or community-matched team members, flyers and information sessions in areas frequented by the population, targeted emails/mailings, and word of mouth referrals. Retention strategies used included having race- or community-matched team members, incentives, being flexible, and facilitating attendance. Most studies used multiple recruitment and retention strategies.

CONCLUSION

This scoping review highlights the importance of a multifaceted recruitment and retention plan for underrepresented populations and populations with arthritis or FM in behavioral intervention programs targeting exercise, physical activity, or chronic disease self management. Additional research is needed to better understand the individual effects of different strategies and the costs associated with the various recruitment/retention methods in underrepresented populations and populations with arthritis.

Data-Driven and Technology-Enabled Trial Innovations Toward Decentralization of Clinical Trials: Opportunities and Considerations

Traditional trial designs have well-recognized inefficiencies and logistical barriers to participation. Decentralized trials and digital health solutions have been suggested as potential solutions and have certainly risen to the challenge during the pandemic. Clinical trial designs are now increasingly data driven. The use of distributed clinical data networks and digitization has helped to fundamentally upgrade existing research systems. A trial design may vary anywhere from fully decentralized to hybrid to traditional on-site. Various decentralization components are available for stakeholders to increase the reach and pace of their trials, such as electronic informed consent, remote interviews, administration, outcome assessment, monitoring, and laboratory and imaging modalities. Furthermore, digital health technologies can be included to enrich study conduct. However, careful consideration is warranted, including assessing verification and validity through usability studies and having various contingencies in place through dedicated risk assessment. Selecting the right combination depends not just on the ability to handle patient care and the medical know-how but also on the availability of appropriate technologic infrastructure, skills, and human resources. Throughout this process, quality of evidence generation and physician-patient relation must not be undermined. Here we also address some knowledge gaps, cost considerations, and potential impact of decentralization and digitization on inclusivity, recruitment, engagement, and retention. Last, we mention some future directions that may help drive the necessary change in the right direction.

Mobile Technologies for Supporting Mental Health in Youths: Scoping Review of Effectiveness, Limitations, and Inclusivity

BACKGROUND

Over the past decade, there has been growing support for the use of mobile health (mHealth) technologies to improve the availability of mental health interventions. While mHealth is a promising tool for improving access to interventions, research on the effectiveness and efficacy of mHealth apps for youths is limited, particularly for underrepresented populations, including youths of color and economically marginalized youths.

OBJECTIVE

This scoping review study sought to evaluate the following research questions: (1) What is the extent of the current literature on mHealth apps that provide intervention for mental health problems in children and adolescents? (2) What is known from the existing literature about the effectiveness or efficacy of delivering mental health services via mHealth apps? (3) What are the gaps in the knowledge base in the fields of technology and mental health? (4) Do the reviewed mHealth apps address issues of cultural sensitivity or have they been tested with underrepresented groups (ie, youths of color or economically marginalized groups)?

METHODS

An electronic database search was conducted using relevant search terms. Seven independent reviewers screened identified studies, including title and abstract review to determine if studies met the following inclusion criteria: (1) targeted samples with mental health symptomology or disorders, (2) studied youth participants aged 6-17 years, and (3) examined the use of a mobile app-based platform for intervention. Relevant studies were subjected to full-text review to extract and chart relevant data based on a priori research questions.

RESULTS

The initial database search yielded 304 papers published from 2010 to 2021. After screening and selection, the final review included 10 papers on the effectiveness and efficacy of mental health intervention apps for youths aged 8 to 17 years. Identified apps targeted a broad range of mental health challenges in youths (ie, depression, self-harm, autism spectrum disorder, anxiety, and obsessive-compulsive disorder). Results identified only a small number of studies suggesting that current effectiveness and efficacy research in this area are limited. While some studies provided general support for the effectiveness of mHealth apps in improving mental health outcomes in youths, several notable limitations were present across the literature, reducing the generalizability of findings. Additionally, considerations around racial, ethnic, and socioeconomic diversity were scarce across studies.

CONCLUSIONS

Although some studies cited in this scoping review provide support for the effectiveness and efficacy of mHealth apps targeting mental health concerns in youths, the overall body of literature remains quite limited. Moreover, mHealth apps expressly developed to be culturally responsive are almost nonexistent. Further efforts are needed to recruit youths who are typically underrepresented in research and invite stakeholder participation and collaborative input in the early stages of the mHealth app development process.

Longitudinal cognitive evaluation before and after delivery among people with preeclampsia

BACKGROUND

Cognitive impairments related to preeclampsia after pregnancy have been reported; however, it is not known if weaknesses in cognition occur before and shortly after delivery.

OBJECTIVE

This study aimed to assess the feasibility of longitudinal cognitive testing before and after delivery, and to investigate whether those with preeclampsia have cognitive weaknesses during the third trimester of pregnancy and at 1 and 3 months postpartum. We hypothesized that people with preeclampsia would have lower cognition scores across all time points compared with normotensive people.

STUDY DESIGN

This longitudinal, prospective, observational study in a single institution enrolled people (N=30) at ≥28 weeks of gestation with preeclampsia (N=16) or normotension (N=14). People with chronic hypertension, neurologic or developmental disabilities, moderate or severe depression or anxiety, or current substance use were excluded. Subjective (Everyday Cognition Scale) and objective assessment of executive function (Stroop Color-Word Interference Test, Trail-Making Test), attention and working memory (Digit Span subtest), and information processing speed (Digit Symbol Substitution Test) was conducted, and Z-scores were calculated. Baseline characteristics (eg, prepregnancy body mass index) were collected from the medical record. Generalized linear models were used to estimate associations.

RESULTS

We enrolled 37% (30/81) of eligible people and retained 80% (24/30) and 53% (16/30) at 1 and 3 months postpartum, respectively. People with preeclampsia reported more memory problems (ß=0.87; 95% confidence interval, 0.44-1.31), and scored worse on attention and working memory (ß=-0.94; 95% confidence interval, -1.42 to -0.45) and executive function (Stroop test ß=-0.86; 95% confidence interval, -1.53 to -0.19) domains compared with normotensive people after adjusting for time, age, education, and prepregnancy body mass index.

CONCLUSION

Longitudinal assessment of cognition in pregnant preeclamptic and normotensive people is feasible. People with preeclampsia reported worse subjective memory and had lower scores in attention, working memory, and executive function.

Engaging adults in organized physical activity: a scoping review of recruitment strategies

Scaling up established physical activity (PA) opportunities for broader population reach requires practitioners to carefully consider strategies implemented to recruit and attract new participants to their PA programs. This scoping review examines the effectiveness of recruitment strategies for engaging adults in organized (established and sustained) PA programs. Electronic databases were searched for articles published between March 1995 and September 2022. Qualitative, quantitative and mixed methods papers were included. Recruitment strategies were assessed against Foster et al. (Recruiting participants to walking intervention studies: a systematic review. Int J Behav Nutr Phys Act 2011;8:137-137.) assessment of quality for reporting recruitment and the determinants of recruitment rates were examined. 8394 titles and abstracts were screened; 22 articles were assessed for eligibility; 9 papers were included. Three of the 6 quantitative papers adopted a combination of passive and active recruitment strategies and 3 relied solely on active strategies. All 6 quantitative papers reported on recruitment rates; 2 evaluated the efficacy of recruitment strategies based on the achieved levels of participation. The evaluation evidence on how individuals are successfully recruited into organized PA programs, and how recruitment strategies influence or address inequities in PA participation, is limited. Culturally sensitive, gender sensitive and socially inclusive recruitment strategies based on building personal relationships show promise for engaging hard-to-reach populations. Improving the reporting and measurement of recruitment strategies into PA programs is essential to better understand which strategies are attracting various population groups thus allowing program implementers to employ recruitment strategies best suited to the needs of their community while making efficient use of program funding.

Telephone Outreach Enhances Recruitment of Underrepresented Seriously Ill Patients for an Advance Care Planning Pragmatic Trial

BACKGROUND

Patients experiencing systemic patterns of disadvantage, such as racial/ethnic minorities and those with limited English proficiency, are underrepresented in research. This is particularly true for large pragmatic trials of potentially sensitive research topics, such as advance care planning (ACP). It is unclear how phone outreach may affect research participation by underrepresented individuals.

OBJECTIVE

To assess the effect of phone outreach, in addition to standard mail survey recruitment, in a population-based ACP pragmatic trial at three academic health systems in California.

DESIGN

Retrospective cohort study PATIENTS: Primary care patients with serious illness were mailed a survey in their preferred language. Patients who did not initially respond by mail received up to three reminder phone calls with the option of survey completion by phone.

MAIN MEASURES

Effect of phone outreach on survey response rate associated with respondent demographic characteristics (e.g., Social Vulnerability Index [SVI], range 0 (low) to 1 (high)).

RESULTS

Across the health systems, 5998 seriously ill patients were mailed surveys. We obtained completed surveys from 1215 patients (20% response rate); 787 (65%) responded after mail alone and 428 (35%) participated only after phone outreach. Patients recruited after phone outreach compared to mail alone were more socially vulnerable (SVI 0.41 v 0.35, P < 0.001), were more likely to report being a racial/ethnic minority (35% v 28%, P = 0.006), and non-English speaking (16% v 10%, P = 0.005). Age and gender did not differ significantly. The inclusion of phone outreach resulted in a sample that better represented the baseline population than mail alone in racial/ethnic minority (28% mail alone, 30% including phone outreach, 36% baseline population), non-English language preference (10%, 12%, 15%, respectively), and SVI (0.35, 0.37, 0.38, respectively).

CONCLUSIONS

Phone outreach for a population-based survey in a pragmatic trial concerning a potentially sensitive topic significantly enhanced recruitment of underrepresented seriously ill patients.

Outcomes among patients with peripheral artery disease in the Aspirin Dosing: A Patient-Centric Trial Assessing Benefits and Long-Term Effectiveness (ADAPTABLE) study

BACKGROUND

We aimed to understand the effects of aspirin dose on outcomes in patients with peripheral artery disease (PAD) as well as their participation in a pragmatic randomized controlled trial.

METHODS

In a subanalysis of the Aspirin Dosing: A Patient-Centric Trial Assessing Benefits and Long-Term Effectiveness (ADAPTABLE) study, we compared aspirin doses (81 vs 325 mg) among participants with PAD and study participation metrics in patients with and without PAD. The primary outcome composite was all-cause mortality, nonfatal myocardial infarction, and nonfatal stroke.

RESULTS

Among 14,662 participants enrolled in ADAPTABLE with PAD status available, 3493 (23.8%) had PAD. Participants with PAD were more likely to experience the primary composite (13.76% vs 5.31%, p < 0.001), all-cause mortality (7.55% vs 3.01%, p < 0.001), myocardial infarction (5.71% vs 2.09%, p < 0.001), stroke (2.45% vs 0.86%, p < 0.001), and major bleeding (1.19% vs 0.44%, p < 0.001). A higher aspirin dose did not reduce the primary outcome in patients with PAD (13.68% vs 13.84% in 81 mg and 325 mg groups; OR 1.05, 95% CI 0.88-1.25). Participants with PAD were less likely to enroll via email (33.0% vs 41.9%, p < 0.0001), less likely to choose internet follow-up (79.2% vs 89.5%, p < 0.0001), and were more likely to change their aspirin doses (39.7% vs 30.7%, p < 0.0001).

CONCLUSIONS

ADAPTABLE participants with PAD did not benefit from a higher dose of aspirin and participated in the study differently from those without PAD. These results reinforce the need for additional PAD-specific research and suggest that different trial strategies may be needed for optimal engagement of patients with PAD.

Recruitment approaches and profiles of consenting family caregivers and people living with dementia: A recruitment study within a trial

Background

While studies have identified strategies that are useful for recruiting people living with dementia, none have focused on psychosocial interventions involving arts therapies, or have examined the profiles of older people living in the community who consent or decline participation, particularly during a global pandemic. We aimed to identify the most effective recruitment strategies according to participant characteristics and transnational differences and develop a profile of consenting and non-consenting participants.

Methods

Recruitment teams in Australia, Norway, Germany, Poland, and the United Kingdom, recorded participants' source of study awareness and characteristics of consenting and non-consenting participants. Distributions of participants 'consenting to participate' were compared and logistic regressions were used to estimate the odds ratios.

Results

Consenting female caregivers were disproportionally represented. Study awareness differed between countries but overall, most expressions of interest to participate were derived from referrals from professionals or organisations, or from databases of people wanting to participate in research. Troughs in recruitment rates occurred during Northern Hemisphere summer vacation periods, and during Christmas periods.

Conclusions

This study found that recruiting for a trial with community-dwelling family caregivers and people living with dementia is challenging, especially during a global pandemic. While spousal caregivers comprised the highest proportion of dyads recruited, overall spousal caregivers were more reluctant to consent to participate than adult child caregivers. More targeted recruitment strategies designed for minority groups are also needed to ensure broader representation in dementia treatment studies.

Piloting a complex intervention to promote a tobacco and alcohol-free pregnancy: the Smoke and Alcohol Free with EHealth and Rewards (SAFER) pregnancy study

BACKGROUND

Tobacco smoking and alcohol consumption before and during pregnancy increase the risk of adverse health outcomes for mother and child. Interventions to address smoking and drinking before and during pregnancy have the potential to reduce early-life health inequalities. In the Smoke and Alcohol Free with EHealth and Rewards (SAFER) pilot study we aimed to evaluate the acceptability, feasibility and effectiveness of a complex intervention supporting women in smoking and alcohol cessation before and during pregnancy.

METHODS

From February 2019 till March 2021, we piloted the SAFER pregnancy intervention among pregnant women and women planning pregnancy in South-West Netherlands in an uncontrolled before-after study. Participants were supported in smoking and alcohol cessation via up to six group sessions and an online platform. In addition, biochemically validated cessation was rewarded with incentives (i.e. shopping vouchers) amounting up to 185 euros. We aimed to include 66 women. The primary outcome was smoking and/or alcohol cessation at 34-38 weeks of gestation (if pregnant) or after six group sessions (if not pregnant). Quantitative data were analysed using descriptive statistics. Focus group interviews among those involved in the study were conducted at the end of the study to explore their experiences. Qualitative data was analysed using thematic analysis.

RESULTS

Thirty-nine women who smoked were included; no women who consumed alcohol were referred to the study. Unemployment (51%), financial problems (36%) and a smoking partner (72%) were common. Thirteen women (33%) dropped out, often due to other problems impeding smoking cessation or 'being too busy' to participate in the group sessions. Eleven women (28%) had quit smoking at the study's endpoint. The personal and positive approach was highly valued and biochemical validation was felt to be helpful.

CONCLUSION

The SAFER pregnancy intervention seems appropriate for women in need of extra support for smoking cessation before and during pregnancy. Its impact on alcohol cessation could not be studied due to recruitment issues. Recruitment and prevention of early dropout need attention in further development of this intervention.

Adaptation of an evidence-based parenting intervention for integration into maternal-child home-visiting programs: Challenges and solutions

Background

The objective of this study was to assess potential challenges, prioritize adaptations, and develop an implementation and research approach to integrate and study a parenting intervention for mothers in recovery from substance use disorders in community-based home-visiting programs.

Method

An explanatory mixed-methods design, guided by process mapping with Failure Modes and Effects Analysis tools, and an Advisory Panel of 15 community members, identified potential implementation challenges and recommended solutions for the proposed intervention within five pre-specified domains. Thematic content analysis identified themes from detailed field notes.

Results

The Advisory Panel identified 44 potential challenges across all domains. They determined that the recruitment domain was most likely to create challenges. Regarding the potential challenges, two cross-domain themes emerged: (1) development of mistrust in the community and (2) difficulty initiating and sustaining engagement. Potential solutions and adaptations to protocols are reported.

Conclusion

Mistrust in the community was cited as a potentially important challenge for the delivery and study of an evidence-based parenting intervention for mothers in recovery through home-visiting programs. Adaptations to research protocols and intervention delivery strategies are needed to prioritize the psychological safety of families, particularly for groups that have been historically stigmatized.

Defining the observable processes of patient care related to social determinants of health

INTRODUCTION

An understanding of social determinants of health (SDH) and patients' social circumstances is recommended to deliver contextualised care. However, the processes of patient care related to SDH in clinical settings have not been described in detail. Observable practice activities (OPAs) are a collection of learning objectives and activities that must be observed in daily practice and can be used to describe the precise processes for professionals to follow in specific situations (process OPA.) METHODS: We used a modified Delphi technique to generate expert consensus about the process OPA for patient care related to SDH in primary care settings. To reflect the opinions of various stakeholders, the expert panel comprised clinical professionals (physicians, nurses, public health nurses, social workers, pharmacists and medical clerks), residents, medical students, researchers (medical education, health care, sociology of marginalised people), support members for marginalised people and patients. The Delphi rounds were conducted online. In Round 1, a list of potentially important steps in the processes of care was distributed to panellists. The list was modified, and one new step was added. In Round 2, all steps were acknowledged with few modifications.

RESULTS

Of 63 experts recruited, 61 participated, and all participants completed the Delphi rounds. A total of 14 observable steps were identified, which were divided into four components: communication, practice, maintenance and advocacy. The importance of ongoing patient-physician relationships and collaboration with professionals and stakeholders was emphasised for the whole process of care.

DISCUSSION

This study presents the consensus of a variety of experts on the process OPA for patient care related to SDHs. Further research is warranted to investigate how this Communication-Practice-Maintenance-Advocacy framework could affect medical education, quality of patient care, and patient outcomes.

Early Maternal Caregiving Capacities in Highly Vulnerable, Multi-Problem Families

Caregiving capacities may be an important link between multi-problem circumstances and adverse child development. This study aims to assess caregiving capacities and their correlations in highly vulnerable, multi-problem families in Rotterdam, the Netherlands. Caregiving capacity (overall, emotional and instrumental) was prospectively assessed in 83 highly vulnerable women using video-observations of daily caregiving tasks, six week postpartum. Supporting data were collected at three time points: at inclusion, six weeks after inclusion and six weeks postpartum, and these included psychological symptoms, self-sufficiency, problematic life domains, home environment, income, depression, anxiety and stress. Pregnancy- and delivery-related information was collected from obstetric care professionals. Maternal caregiving scores averaged below adequate quality. Mothers living in an unsafe home environment (B = 0.62) and mothers with more problematic life domains (≤3 domains, B = 0.32) showed significantly higher instrumental caregiving capacities. Other variables were not related to caregiving capacities. Caregiving capacity in this highly vulnerable population was below adequate quality. However, in most cases there was no significant association between caregiving and the variables related to vulnerability. This means that a potential association between vulnerability and caregiving capacities might be driven by the interaction between several problems, rather than the type or number of problems.

The Impact of Interpretation Services Training on Contact Tracing Efforts During the COVID-19 Pandemic

There is limited research regarding interpretation services training and its benefit in contact tracing programs. This study seeks to assess the impact of optional formal interpretation services training on contact tracers and identify specific barriers tracers face when contacting patients with limited English proficiency, who have been disproportionately impacted by the COVID-19 pandemic.

Process evaluation of a pragmatic implementation trial to support self-management for the prevention and management of type 2 diabetes in Uganda, South Africa and Sweden in the SMART2D project

INTRODUCTION

Type 2 diabetes (T2D) and its complications are increasing rapidly. Support for healthy lifestyle and self-management is paramount, but not adequately implemented in health systems. Process evaluations facilitate understanding why and how interventions work through analyzing the interaction between intervention theory, implementation and context. The Self-Management and Reciprocal Learning for Type 2 Diabetes project implemented and evaluated community-based interventions (peer support program; care companion; and link between facility care and community support) for persons at high risk of or having T2D in a rural community in Uganda, an urban township in South Africa, and socioeconomically disadvantaged urban communities in Sweden.

RESEARCH DESIGN AND METHODS

This paper reports implementation process outcomes across the three sites, guided by the Medical Research Council framework for complex intervention process evaluations. Data were collected through observations of peer support group meetings using a structured guide, and semistructured interviews with project managers, implementers, and participants.

RESULTS

The countries aligned implementation in accordance with the feasibility and relevance in the local context. In Uganda and Sweden, the implementation focused on peer support; in South Africa, it focused on the care companion part. The community-facility link received the least attention. Continuous capacity building received a lot of attention, but intervention reach, dose delivered, and fidelity varied substantially. Intervention-related and context-related barriers affected participation.

CONCLUSIONS

Identification of the key uncertainties and conditions facilitates focus and efficient use of resources in process evaluations, and context relevant findings. The use of an overarching framework allows to collect cross-contextual evidence and flexibility in evaluation design to adapt to the complex nature of the intervention. When designing interventions, it is crucial to consider aspects of the implementing organization or structure, its absorptive capacity, and to thoroughly assess and discuss implementation feasibility, capacity and organizational context with the implementation team and recipients. These recommendations are important for implementation and scale-up of complex interventions.

Community-Based Participatory Research (CBPR) to Enhance Participation of Racial/Ethnic Minorities in Clinical Trials: A 10-Year Systematic Review

There has not been a significant improvement in the rate of clinical trial accrual in more than 20 years. Worse, the challenge of inadequate representation among racial and ethnic minorities also persists, deepening disparities in health. Community-Based Participatory Research (CBPR) is a participatory communication method that centers on effective dialogue between researchers and community stakeholders with the goal of creating an equitable partnership for health and social change. The objective of the current study was to provide an update since a systematic review in 2012, on the current status of the empirical research, with a particular focus on the elements of CBPR methods used to improve the rate of accrual of members of racial and ethnic minority communities for clinical trials. Our systematic review found a large increase in the number of CBPR related studies and studies related to racial and ethnic representation in research. More than 85% of studies employing CBPR methods saw statistically positive outcomes. Specifically, the elements of CBPR that are associated with these positive outcomes include community partner participation in (1) a study advisory committee, (2) data collection, (3) the development of interventions, and (4) participant recruitment. However, the results of our study indicate that researchers need to be more transparent about the extent of community participation as well as more thoroughly and accurately describe the nature of the partnership with members of minority communities in order to build upon the scientific literature on community-engaged methods.

Social determinants and lifestyle factors for brain health: implications for risk reduction of cognitive decline and dementia

Substantial evidence indicates a huge potential for risk reduction of cognitive decline and dementia based on modifiable health and lifestyle factors. To maximize the chances for risk reduction, it is useful to investigate associations of social determinants and lifestyle for brain health. We computed the "LIfestyle for BRAin health" (LIBRA) score for baseline participants of the Leipzig Research Centre for Civilization Diseases (LIFE) Adult Study, a population-based urban cohort in Germany. LIBRA predicts dementia in midlife and early late life populations, comprising 12 modifiable risk factors (heart disease, kidney disease, diabetes, obesity, hypertension, hypercholesterolemia, alcohol consumption, smoking, physical inactivity, diet, depression, cognitive inactivity). Associations of social determinants (living situation, marital status, social isolation, education, net equivalence income, occupational status, socioeconomic status/SES, employment) with LIBRA were inspected using age- and sex-adjusted multivariable linear regression analysis. Z-standardization and sampling weights were applied. Participants (n = 6203) were M = 57.4 (SD = 10.6, range 40-79) years old and without dementia, 53.0% were women. Except for marital status, all considered social determinants were significantly associated with LIBRA. Beta coefficients for the association with higher LIBRA scores were most pronounced for low SES (β = 0.80, 95% CI [0.72-0.88]; p < 0.001) and middle SES (β = 0.55, 95% CI [0.47-0.62]; p < 0.001). Social determinants, particularly socioeconomic factors, are associated with lifestyle for brain health, and should thus be addressed in risk reduction strategies for cognitive decline and dementia. A social-ecological public health perspective on risk reduction might be more effective and equitable than focusing on individual lifestyle behaviors alone.

Multidomain interventions for risk reduction and prevention of cognitive decline and dementia: current developments

PURPOSE OF REVIEW

The potential for dementia prevention is deemed substantial if modifiable risk factors were addressed. First large-scale multidomain lifestyle interventions aiming at reducing risk of cognitive decline and dementia have yielded mixed but promising evidence.

RECENT FINDINGS

Despite the impact of the COVID-19 pandemic on trials conduction, causing interruptions and delays, the research landscape on multidomain interventions is growing rapidly. The successful Finish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) has led to an adaptation of the FINGER model in trials underway or being planned in over 40 countries. Recent studies identified barriers and facilitators of and adherence to multidomain interventions, showed the suitability of dementia risk scores as surrogate outcomes, and suggested mechanisms. Multidomain interventions are increasingly conducted in the Global South, and study protocols are increasingly testing expanded FINGER models, for example, with pharmacological components, in digital/remote settings and co-designed personalized interventions.

SUMMARY

Though results remain mixed, the many ongoing trials will provide more conclusive evidence within the next few years and help to optimize interventions. Continued international collaboration is pivotal to scale and accelerate the development and implementation of effective multidomain interventions as part of larger public health strategies to counteract the global dementia increase.

Moving the Dial Toward Equity in Parkinson's Disease Clinical Research: a Review of Current Literature and Future Directions in Diversifying PD Clinical Trial Participation

PURPOSE OF REVIEW

Parkinson's disease (PD), the second most common neurodegenerative disease, has a worldwide prevalence projected at 12 million by 2040. While PD has been extensively researched, our understanding of the disease is based on research studies that include mostly participants of European descent. The lack of diversity in clinical trial enrollment has limited the generalizability of scientific discoveries in the field. Here, we discuss contributors to racial and ethnic disparities in PD clinical research enrollment, summarize recently proposed and tested interventions, and propose next steps to increase equity and representation in PD research.

RECENT FINDINGS

Enrollment in PD clinical research is vulnerable to upstream disparities and inequities from PD awareness to access to specialized PD centers. While additional research is still needed, recent studies have identified some potential strategies for increasing underrepresented minority (URM) recruitment including increasing the availability of linguistically and culturally diverse research materials and team members, partnering with community organizations, and forming relationships with URM-serving community physicians. To move the dial toward equity in PD research, it will be necessary to implement known successful strategies and further investigate additional contributors to the underrepresentation of URMs in PD clinical research while developing and testing interventions to address these factors.

Patient-centred clinical trial design

Patient involvement in clinical trial design can facilitate the recruitment and retention of participants as well as potentially increase the uptake of the tested intervention and the impact of the findings on patient outcomes. Despite these benefits, patients still have very limited involvement in designing and conducting trials in nephrology. Many trials do not address research questions and outcomes that are important to patients, including patient-reported outcomes that reflect how patients feel and function. This limitation can undermine the relevance, reliability and value of trial-based evidence for decision-making in clinical practice and health policy. However, efforts to involve patients with kidney disease are increasing across all stages of the trial process from priority setting, to study design (including selection of outcomes and approaches to improve participant recruitment and retention) and dissemination and implementation of the findings. Harnessing the patient voice in designing trials can ensure that efforts and resources are directed towards patient-centred trials that address the needs, concerns and priorities of patients living with kidney disease with the aim of achieving transformative improvements in care and outcomes.

Traversing the Aging Research and Health Equity Divide: Toward Intersectional Frameworks of Research Justice and Participation

Meaningful reductions in racial and ethnic inequities in chronic diseases of aging remain unlikely without major advancements in the inclusion of minoritized populations in aging research. While sparse, studies investigating research participation disparities have predominantly focused on individual-level factors and behavioral change, overlooking the influence of study design, structural factors, and social determinants of health on participation. This is also reflected in conventional practices that consistently fail to address established participation barriers, such as study requirements that impose financial, transportation, linguistic, and/or logistical barriers that disproportionately burden participants belonging to minoritized populations. These shortcomings not only risk exacerbating distrust toward research and researchers, but also introduce significant selection biases, diminishing our ability to detect differential mechanisms of risk, resilience, and response to interventions across subpopulations. This forum article examines the intersecting factors that drive both health inequities in aging and disparate participation in aging research among minoritized populations. Using an intersectional, social justice, and emancipatory lens, we characterize the role of social determinants, historical contexts, and contemporaneous structures in shaping research accessibility and inclusion. We also introduce frameworks to accelerate transformative theoretical approaches to fostering equitable inclusion of minoritized populations in aging research.

Meeting ethical challenges with authenticity when engaging patients and families in end-of-life and palliative care research: a qualitative study

BACKGROUND

Delivering high quality, patient- and family-centered care depends upon high quality end-of-life and palliative care (EOLPC) research. Engaging patients and families as advisors, partners, or co-investigators throughout the research lifecycle is widely regarded as critical to ensuring high quality research. Engagement is not only an ethical obligation, it also raises ethical challenges of its own. We conducted a qualitative study to understand ethical challenges and potential solutions when engaging patients and families in EOLPC research.

METHODS

We recruited and interviewed 20 clinical investigators and 22 patients or family caregivers through the Palliative Care Research Cooperative Group (PCRC). Interview transcripts were analyzed using constructivist grounded theory methodology. Analysis sought to identify ethical challenges and potential solutions, as well as to synthesize findings into practical recommendations tailored to engaging patients and families in EOLPC research.

RESULTS

Our study identified 8 ethical challenges considered unique to the EOLPC research context and 11 potential solutions to these challenges. The most frequently described ethical challenges included the need to minimize burdens of engagement for patients and caregivers, challenges of dealing with death and illness, and paternalism or "gatekeeping" (i.e., withholding the opportunity to participate from patients or caregivers). Investigators and patients or family caregivers conceptualized ethics challenges differently; several issues appeared to fall outside a traditional research ethics paradigm and more into the ethics of relationships. We synthesized these findings into 4 practical recommendations hypothesized to support authentic engagement.

CONCLUSIONS

Engaging patients and families in EOLPC research can raise unique ethical challenges. These challenges can be overcome to empower participation, minimize the unique burdens of EOLPC, and promote diversity. Whereas traditional research ethics tend to emphasize protecting research participants who may be vulnerable, an ethics approach based on authentic engagement that explores what it means for investigators and patients or family caregivers to be in a relationship may be needed. Future research is needed to explore this approach and test these recommendations in practice.

As Steady as a Rock! Gaining Insight in Recruitment and Retention Among Primary School Children With Behavioural Problems in Sport Mix Club

The number of children dealing with behavioural problems is increasing. A major challenge in many health-supportive programmes is the recruitment and retention of these children. In the current study, Sport Mix Club (SMC), an approach to enhance socioemotional disorders of 4- to 12-year-old children through sport classes in municipality Vaals, the Netherlands, is used as an illustration. Where many studies faced difficulties getting and keeping children in their interventions, SMC overcame this challenge. Therefore, we decided to explore "What factors contribute to enhanced recruitment and retention procedures among children with behavioural problems in Sport Mix Club?" A qualitative case study design using the analysis of the administrative logbook of the SMC coach and trainees, individual interviews with the SMC coach, trainees (n = 2), school teachers (n = 3) and parents of participating children (n = 9), and four focus group interviews with children (n = 13) were carried out. During the recruitment and retention of SMC, the human psychological need of relatedness seemed to be of crucial value. The fact that the SMC coach: (1) made efforts to become a familiar face for children, parents and community partners beforehand; (2) showed enthusiasm; and (3) placed her focus on having fun as opposed to the children's problems, seemed to be decisive in the process of getting children to participate in SMC and retaining their participation.

Lessons Learned: Recruiting Research Participants from an Underrepresented Patient Population at a Safety Net Hospital

BACKGROUND

Recruiting participants to clinical research studies is challenging, especially when conducted in safety net settings. We sought to compare the efficacy of different recruitment strategies in an NIH-funded study assessing treatment burden in patients with multiple chronic conditions (MCCs).

METHODS

Targeted mailing, in-person table-based recruitment ("tabling") in the waiting room, and telephone calling were used to enroll subjects into one of two studies of treatment burden: a survey study to validate a brief measure of treatment burden for quality assessment (study 1) or a qualitative study to develop a treatment burden clinical communication tool (study 2).

RESULTS

Over 50% of subjects in each study were African American or African immigrants. In study 1, the enrollment goal of 200 was reached within 4 months. Tabling enrolled 78.5% of patients, while the remainder (21.5%) were enrolled from phone calls to eligible patients identified through the electronic medical record (EMR). In study 2, 340 eligible patients were identified through the EMR, and 7 (2.1%) were successfully enrolled via mailed invitations and responses. Retention rates (66% in study 1 and 71% in study 2) were reasonable in all groups.

CONCLUSIONS

Study recruiting goals in our safety net population were rapidly reached using the tabling method, which had substantively higher enrollment rates than mailings or telephone calls based on EMR reports. Future trials could compare recruitment strategies across settings and clinical populations.

A salutogenesis approach to ageing with impairment: the managing and coping experiences of older people ageing with deafblindness

An understanding of the psychosocial impact of deafblindness on older people is impoverished by a dearth of research in the field. Particularly limited are studies adopting a salutogenesis perspective, in which older deafblind people's coping capacities are explored. Much research focuses on vulnerability to unfavourable outcomes, which may perpetuate negative stereotypes of deafblind people as passive and dependent. Identifying deafblind people as a vulnerable group gives rise to misunderstanding of the impairment, perceptions of incapability and neglect of deafblind people's agency. This paper draws on data from the first United Kingdom-based study of vulnerability from the perspectives of older adults ageing with deafblindness. Findings presented here relate to participants’ experiences of managing and coping with their felt vulnerability and ageing with deafblindness. The study adopted interpretative phenomenological analysis (IPA) as its qualitative approach. In-depth semi-structured interviews were undertaken between October 2014 and July 2016 with eight participants, aged between 48 and 83 years. Data were analysed using an iterative six-step IPA process. Three superordinate themes were identified: taking action to protect self; psychological coping strategies; and accessing and using care and support. Participants’ managing and coping strategies, and the care and support they value, respond to elements identified as generating felt vulnerability. Professionals should seek to bolster coping capacity and provide support in ways valued by those ageing with deafblindness.

The Relationship Between Attitudes about Research and Health Literacy among African American and White (Non-Hispanic) Community Dwelling Older Adults

BACKGROUND

Ethnic minority representation lacks in research. Understanding factors that promote minorities in research helps address this participation gap. Minorities often face representation disparities, including health education, socioeconomic status, and race. Compared to other races in the USA, over 50% of African Americans (AA) over age 65 face obstacles towards achieving basic health literacy skills. This study aims to investigate differences in beliefs regarding research and health literacy between White and AA participants.

METHODS

This cross-sectional study compared 46 AA vs. 60 White healthy older adults (n = 106; age = 73.97 ± 10.6 years). Participants were assessed once with the Participant Attitudes and Beliefs towards Research Questionnaire (PABRQ) and two validated health literacy measures, the Rapid Estimate of Adult Literacy in Medicine (REALM) and the Short Test of Functional Health Literacy for Adults (S-TOFHLA).

RESULTS

Controlling for age, sex, and education, AA performed significantly worse on REALM. Compared to White participants, AA more likely believed that researchers were motivated to perform studies to increase their general knowledge. Participants with lower health literacy scores more likely believed that scientists were motivated to conduct research to minimize treatment expenses. About 83-85% of participants reported not being familiar with the informed consent process, 90-95% had positive attitudes towards research involvement, and 38-52% believed researchers performed to promote their own careers.

CONCLUSION

This work helps link older adults' beliefs towards research, health literacy, and their participation in research. Future research is needed to remove barriers to participation in research for underserved, older adults.

Persistent pain and long-term physical and mental conditions and their association with psychological well-being; data from 10,744 individuals from the Lolland-Falster health study

INTRODUCTION

Persistent pain (PP) and long-term conditions are all associated with psychological well-being. Less is known about their associations with reduced psychological well-being when co-occurring. We investigated how PP and long-term physical and mental conditions relate to psychological well-being when occurring together.

METHOD

Data collected in the Danish population-based Lolland-Falster Health study were used in this cross-sectional study. Participants aged ≥18 years completing questions concerning PP, long-term conditions and psychological well-being were included. PP and long-term conditions were defined as conditions lasting 6 months or longer. Psychological well-being was assessed by the World Health Organization Well-Being Index (WHO-5). Multiple linear regression investigated combinations of PP and physical and mental long-term conditions and their associations with WHO-5.

RESULTS

Of 11,711 participants, 10,744 had available data. One third had PP (n = 3250), while 6144 (57%), 213 (2%) and 946 (9%) reported having only physical conditions, only mental conditions or both, respectively. All combinations of PP and long-term conditions were negatively associated with WHO-5. PP in combination with mental (-23.1 (95% CI -28.3 to -17.8)) or both physical and mental conditions (-25.1 (-26.7 to -23.52) yielded the strongest negative associations. Two or more pain sites together with long-term physical and mental conditions was associated with a lower WHO-5 score (-6.2 (-8.9 to -3.5) compared to none or one pain site.

CONCLUSION

The presence of PP and long-term conditions, in particular mental conditions, were strongly associated with worse psychological well-being. This highlights the importance of assessing psychological well-being in individuals with PP and long-term conditions.

Design, analysis, and reporting of pilot studies in HIV: a systematic review and methodological study

Background

Pilot studies are essential in determining if a larger study is feasible. This is especially true when targeting populations that experience stigma and may be difficult to include in research, such as people with HIV. We sought to describe how pilot studies have been used to inform HIV clinical trials.

Methods

We conducted a methodological study of pilot studies of interventions in people living with HIV published until November 25, 2020, using Medline, Embase, and Cochrane Controlled Register of Trials (CENTRAL). We extracted data on their nomenclature, primary objective, use of progression criteria, sample size, use of qualitative methods, and other contextual information (region, income, level, type of intervention, study design).

Results

Our search retrieved 10,597 studies, of which 248 were eligible. The number of pilot studies increased steadily over time. We found that 179 studies (72.2%) used the terms “pilot” or “feasibility” in their title, 65.3% tested feasibility as a primary objective, only 2% used progression criteria, 23.9% provided a sample size estimation and only 30.2% used qualitative methods.

Conclusions

Pilot studies are increasingly being used to inform HIV research. However, the titles and objectives are not always consistent with piloting. The design and reporting of pilot studies in HIV could be improved.

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.

Recruiting Participants for Population Health Intervention Research: Effectiveness and Costs of Recruitment Methods for a Cohort Study

Background

Public health research studies often rely on population-based participation and draw on various recruitment methods to establish samples. Increasingly, researchers are turning to web-based recruitment tools. However, few studies detail traditional and web-based recruitment efforts in terms of costs and potential biases.

Objective

This study aims to report on and evaluate the cost-effectiveness, time effectiveness, and sociodemographic representation of diverse recruitment methods used to enroll participants in 3 cities of the Interventions, Research, and Action in Cities Team (INTERACT) study, a cohort study conducted in Canadian cities.

Methods

Over 2017 and 2018 in Vancouver, Saskatoon, and Montreal, the INTERACT study used the following recruitment methods: mailed letters, social media (including sponsored Facebook advertisements), news media, partner communications, snowball recruitment, in-person recruitment, and posters. Participation in the study involved answering web-based questionnaires (at minimum), activating a smartphone app to share sensor data, and wearing a device for mobility and physical activity monitoring. We describe sociodemographic characteristics by the recruitment method and analyze performance indicators, including cost, completion rate, and time effectiveness. Effectiveness included calculating cost per completer (ie, a participant who completed at least one questionnaire), the completion rate of a health questionnaire, and the delay between completion of eligibility and health questionnaires. Cost included producing materials (ie, printing costs), transmitting recruitment messages (ie, mailing list rental, postage, and sponsored Facebook posts charges), and staff time. In Montreal, the largest INTERACT sample, we modeled the number of daily recruits through generalized linear models accounting for the distributed lagged effects of recruitment campaigns.

Results

Overall, 1791 participants were recruited from 3 cities and completed at least one questionnaire: 318 in Vancouver, 315 in Saskatoon, and 1158 in Montreal. In all cities, most participants chose to participate fully (questionnaires, apps, and devices). The costs associated with a completed participant varied across recruitment methods and by city. Facebook advertisements generated the most recruits (n=687), at a cost of CAD $15.04 (US $11.57; including staff time) per completer. Mailed letters were the costliest, at CAD $108.30 (US $83.3) per completer but served to reach older participants. All methods resulted in a gender imbalance, with women participating more, specifically with social media. Partner newsletters resulted in the participation of younger adults and were cost-efficient (CAD $5.16 [US $3.97] per completer). A generalized linear model for daily Montreal recruitment identified 2-day lag effects on most recruitment methods, except for the snowball campaign (4 days), letters (15 days), and reminder cards (5 days).

Conclusions

This study presents comprehensive data on the costs, effectiveness, and bias of population recruitment in a cohort study in 3 Canadian cities. More comprehensive documentation and reporting of recruitment efforts across studies are needed to improve our capacity to conduct inclusive intervention research.

Reach Outcomes and Costs of Different Physician Referral Strategies for a Weight Management Program Among Rural Primary Care Patients: Type 3 Hybrid Effectiveness-Implementation Trial

BACKGROUND

Rural residents are at high risk for obesity; however, little resources exist to address this disproportional burden of disease. Primary care may provide an opportunity to connect primary care patients with overweight and obesity to effective weight management programming.

OBJECTIVE

The purpose of this study is to examine the utility of different physician referral and engagement processes for improving the reach of an evidence-based and technology-delivered weight management program with counseling support for rural primary care patients.

METHODS

A total of 5 rural primary care physicians were randomly assigned a sequence of four referral strategies: point-of-care (POC) referral with active telephone follow-up (ATF); POC referral, no ATF; a population health registry-derived letter referral with ATF; and letter referral, no ATF. For registry-derived referrals, physicians screened a list of patients with BMI ≥25 and approved patients for participation to receive a personalized referral letter via mail.

RESULTS

Out of a potential 991 referrals, 573 (57.8%) referrals were made over 16 weeks, and 98 (9.9%) patients were enrolled in the program (58/98, 59.2% female). Differences based on letter (485/991, 48.9%) versus POC (506/991, 51.1%) referrals were identified for completion (100% vs 7%; P<.001) and for proportion screened (36% vs 12%; P<.001) but not for proportion enrolled (12% vs 8%; P=.10). Patients receiving ATF were more likely to be screened (47% vs 7%; P<.001) and enrolled (15% vs 7%; P<.001) than those not receiving ATF. On the basis of the number of referrals made in each condition, we found variations in the proportion and number of enrollees (POC with ATF: 27/190, 50%; POC no ATF: 14/316, 41%; letter ATF: 30/199; 15.1%; letter no ATF: 27/286, 9.4%). Across all conditions, participants were representative of the racial and ethnic characteristics of the region (60% female, P=.15; 94% White individuals, P=.60; 94% non-Hispanic, P=.19). Recruitment costs totaled US $6192, and the overall recruitment cost per enrolled participant was US $63. Cost per enrolled participant ranged from POC with ATF (US $47), registry-derived letter without ATF (US $52), and POC without ATF (US $56) to registry-derived letter with ATF (US $91).

CONCLUSIONS

Letter referral with ATF appears to be the best option for enrolling a large number of patients in a digitally delivered weight management program; however, POC with ATF and letters without ATF yielded similar numbers at a lower cost. The best referral option is likely dependent on the best fit with clinical resources.

Using increased trust in medical researchers to increase minority recruitment: The RECRUIT cluster randomized clinical trial

While extensive literature exists on barriers and strategies to increase minority participation in clinical trials, progress is limited. Few strategies were evaluated in randomized trials. We studied the impact of RECRUIT, a trust-based, cluster randomized minority recruitment trial layered on top of four traditional NIH-funded parent trials (BMT CTN, CABANA, PACES, STEADY-PD III; fifty specialty sites). RECRUIT was conducted from July 2013 through April 2017. Intervention sites implemented trust-based approaches customized to individual sites, promoting relationships between physician-investigators and minority-serving physicians and their minority patients. Control sites implemented only parent trials' recruitment procedures. Adjusting for within-site clustering, we detected no overall intervention effect, odds ratio 1.3 (95% confidence limits 0.7,2.4). Heterogeneity among parent trials may have obscured the effect. Of the four parent trials, three enrolled more minorities in intervention versus control sites. CABANA odds ratio = 4.2 (adjusted 95%CL 1.5,11.3). PACES intervention sites enrolled 63% (10/16) minorities; control sites enrolled one participant in total, a minority, yielding an incalculable odds ratio. STEADY-PD III odds ratio = 2.2 (adjusted 95%CL 0.6,8.5). BMT CTN odds ratio < 1, 0.8 (adjusted 95%CL 0.4,1.8). In conclusion, RECRUIT findings suggest the unique trust-based intervention increased minority recruitment to intervention trials in ¾ of studied trials. Physician-investigators' participation was critical to recruitment success. Lack of commitment to minority recruitment remained a barrier for some physician-investigators, especially in control sites. We recommend prospective physician investigators commit to minority recruitment activities prior to selection as site investigators and trial funding include some compensation for minority recruitment efforts.

The MoveStrong program for promoting balance and functional strength training and adequate protein intake in pre-frail older adults: A pilot randomized controlled trial

BACKGROUND

Balance and functional strength training can improve muscle strength and physical functioning outcomes and decrease the risk of falls in older adults. To maximize the benefits of strength training, adequate protein intake is also important. However, the number of older individuals that consume enough protein or routinely engage in strength training remains low at less than 5% and even lower for activities that challenge balance. Our primary aim was to assess the feasibility of implementing a model (MoveStrong) of service delivery to teach older adults about balance and functional strength training and methods to increase protein intake.

METHODS

This study was a closed cohort stepped wedge randomized controlled trial. We recruited individuals ≥60 years considered pre-frail or frail with at least one chronic condition who were not currently engaging in regular strength training from Northern (rural) and Southern (urban) Ontario sites in Canada. The primary outcome was feasibility of implementation, defined by recruitment, retention, and adherence, and safety (defined by monitoring adverse events). We also reported participants' and providers' experience with MoveStrong, adaptations to the model based on participant's and provider's experience, and program fidelity.

RESULTS

We recruited 44 participants to the study and the average adherence rate was 72% with a retention of 71%. The program had a high-fidelity score. One person experienced a fall-related injury during exercise, while two other participants reported pain during certain activities. Five individuals experienced injuries or health problems that were not related to the program. Suggestions for future trials include modifying some exercises, exploring volunteer assistance, increasing the diversity of participants enrolled, and considering a different study design.

CONCLUSIONS

Our pilot trial demonstrates the feasibility of recruitment and adherence for a larger multisite RCT of balance and functional strength training with attention to protein intake in pre-frail and frail older adults.

Insight into the process of postpartum care utilisation and in-home support among vulnerable women in the Netherlands: an in-depth qualitative exploration

OBJECTIVE

To gain insight into the process of postpartum care utilisation and in-home support among vulnerable women.

DESIGN, METHOD, PARTICIPANTS AND SETTING

A qualitative interview study was conducted among 23 pregnant and postpartum vulnerable women in the Netherlands, following a grounded theory approach. Women were determined as vulnerable by their healthcare providers. Theoretical sampling of participants was applied and was alternated by data analysis to include information-rich cases until saturation was achieved.

RESULTS

A conceptual framework of postpartum care utilisation was generated consisting of three phases: pregnancy, early postpartum period and late postpartum period. Within these phases, information provision, parenting self-efficacy and social network were identified as overarching themes. Perceived inadequate information on content of postpartum care posed a major barrier to forming realistic expectations during pregnancy and hindered its utilisation. Low self-efficacy facilitated postpartum care utilisation. All women experienced increased self-efficacy during and after postpartum care. Support from a social network influenced expectations regarding the added value of postpartum care during pregnancy, and lowered actual utilisation during the postpartum period. The costs of postpartum care and the role of the maternity care assistant acted as general barriers or facilitators influencing the three overarching themes and therefore postpartum care utilisation indirectly.

CONCLUSIONS

Our findings suggest that postpartum care utilisation among vulnerable women may be improved by considering the particular phase and relevant themes applying to individual women, and adapt care accordingly. We recommend to provide comprehensive, understandable information and to emphasise the gains of postpartum care in improving self-efficacy for vulnerable women. Moreover, involving a woman's social network in postpartum care may add value to this care for this population.
