Recruiting Chinese Americans into cancer screening intervention trials: strategies and outcomes

REPRESENT recommendations: improving inclusion and trust in cancer early detection research

Detecting cancer early is essential to improving cancer outcomes. Minoritized groups remain underrepresented in early detection cancer research, which means that findings and interventions are not generalisable across the population, thus exacerbating disparities in cancer outcomes. In light of these challenges, this paper sets out twelve recommendations to build relations of trust and include minoritized groups in ED cancer research. The Recommendations were formulated by a range of stakeholders at the 2022 REPRESENT consensus-building workshop and are based on empirical data, including a systematic literature review and two ethnographic case studies in the US and the UK. The recommendations focus on: Long-term relationships that build trust; Sharing available resources; Inclusive and accessible communication; Harnessing community expertise; Unique risks and benefits; Compensation and support; Representative samples; Demographic data; Post-research support; Sharing results; Research training; Diversifying research teams. For each recommendation, the paper outlines the rationale, specifications for how different stakeholders may implement it, and advice for best practices. Instead of isolated recruitment, public involvement and engagement activities, the recommendations here aim to advance mutually beneficial and trusting relationships between researchers and research participants embedded in ED cancer research institutions.

Enrollment of Racial and Ethnic Minoritized Groups in Gynecologic Oncology Clinical Trials: A Review of the Scope of the Problem, Contributing Factors, and Strategies to Improve Inclusion

Racial inequities are well-documented across the gynecologic oncology care continuum, including the representation of racial and ethnic minoritized groups (REMGs) in gynecologic oncology clinical trials. We specifically reviewed the scope of REMG disparities, contributing factors, and strategies to improve inclusion. We found systematic and progressively worsening under-enrollment of REMGs, particularly of Black and Latinx populations. In addition, race/ethnicity data reporting is poor, yet a prerequisite for accountability to recruitment goals. Trial participation barriers are multifactorial, and successful remediation likely requires multi-level strategies. More rigorous, transparent data on trial participants and effectiveness studies on REMG recruitment strategies are needed to improve enrollment.

Recruiting foreign-born individuals who have sought an abortion in the United States: Lessons from a feasibility study

Although studies have documented challenges people encounter when attempting to access abortion care in the United States, there is little research on the perspectives and experiences of foreign-born individuals, who may encounter unique barriers to accessing care. Since lack of data may be due to difficulty recruiting this population, we explored the feasibility of using social media to recruit foreign-born individuals who have sought an abortion into interviews to share their abortion experiences. Our target population was limited to English and Spanish-speakers due to budget constraints. As this recruitment method was unsuccessful, we attempted to recruit our target population through the crowdsourcing website, Amazon Mechanical Turk (mTurk) to take a one-time survey on their abortion experience. Both online recruitment methods yielded a significant number of fraudulent responses. Although we aimed to collaborate with organizations that work closely with immigrant populations, they were unavailable to assist with recruitment efforts at the time of the study. Future abortion research utilizing online methods to recruit foreign-born populations should consider incorporating information on their target populations' use of online platforms as well as cultural views on abortion in order to develop effective recruitment strategies.

Promoting inclusion in clinical trials-a rapid review of the literature and recommendations for action

Background

Without inclusion of diverse research participants, it is challenging to understand how study findings will translate into the real world. Despite this, a lack of inclusion of those from under-served groups in research is a prevailing problem due to multi-faceted barriers acting at multiple levels. Therefore, we rapidly reviewed international published literature, in relation to clinical trials, on barriers relating to inclusion, and evidence of approaches that are effective in overcoming these.

Methods

A rapid literature review was conducted searching PubMed for peer-reviewed articles that discussed barriers to inclusion or strategies to improve inclusion in clinical trial research published between 2010 and 2021. Grey literature articles were excluded.

Results

Seventy-two eligible articles were included. The main barriers identified were language and communication, lack of trust, access to trials, eligibility criteria, attitudes and beliefs, lack of knowledge around clinical trials, and logistical and practical issues. In relation to evidence-based strategies and enablers, two key themes arose: [1] a multi-faceted approach is essential [2]; no single strategy was universally effective either within or between trials. The key evidence-based strategies identified were cultural competency training, community partnerships, personalised approach, multilingual materials and staff, communication-specific strategies, increasing understanding and trust, and tackling logistical barriers.

Conclusions

Many of the barriers relating to inclusion are the same as those that impact trial design and healthcare delivery generally. However, the presentation of these barriers among different under-served groups may be unique to each population’s particular circumstances, background, and needs. Based on the literature, we make 15 recommendations that, if implemented, may help improve inclusion within clinical trials and clinical research more generally. The three main recommendations include improving cultural competency and sensitivity of all clinical trial staff through training and ongoing personal development, the need to establish a diverse community advisory panel for ongoing input into the research process, and increasing recruitment of staff from under-served groups. Implementation of these recommendations may help improve representation of under-served groups in clinical trials which would improve the external validity of associated findings.

Assessing the feasibility, acceptability and impacts of an education program on hepatitis B testing uptake among ethnic Chinese in Australia: results of a randomised controlled pilot study

Background

In Australia, Chinese migrants are among the populations most affected by hepatitis B virus (HBV) infection but often experience late diagnosis or access to clinical care. This study aims to explore approaches to increase HBV testing in Australia’s Chinese community and inform evaluation planning, specifically to i) assess the feasibility and acceptability of HBV educational programs, and ii) compare HBV testing uptake in people receiving a tailored education resource focussing on liver cancer prevention compared with a standard HBV education package.

Methods

This is a pre-post mixed-methods pilot and feasibility study. People of Chinese ethnicity and unsure of their HBV infection or immunity status were recruited from ten community sites in Melbourne, Australia in 2019–2020. Participants were randomised to receive an education package (comprised of a leaflet and in-person one-on-one educational session) with a focus on either 1) standard HBV-related information, or 2) liver cancer prevention. Participants completed a baseline questionnaire prior to receiving the intervention and were followed up at 6 months’ time for a questionnaire and an opt-in semi-structured interview. Primary study outcomes included feasibility of study procedures, measured by recruitment, participation, and retention rates; acceptability of the education program assessed by acceptability scores; and HBV testing uptake rate in each arm. Secondary outcomes include HBV-related knowledge change, assessed by pre-post comparison; and factors affecting participants’ testing behaviour analysed using qualitative data.

Results

Fifty-four participants received an education package; baseline and follow-up data from 33 (61%) were available. The study procedures of recruitment and retention were feasible; the acceptability of the education program was moderate with improved HBV-related knowledge observed. Four participants self-reported being tested: one (1/15, 7%) in the standard HBV information group and three (3/18, 17%) in the liver cancer prevention information group. Factors identified as affecting testing included perceived relevance and seriousness of HBV, healthcare access and costs of testing, and perceptions of the role of primary care providers in HBV-related care.

Conclusion

A tailored education program targeting ethnic Chinese in Australia was feasible with moderate acceptability. A larger study is required to determine if a liver cancer prevention message would improve HBV testing uptake in Chinese community than standard HBV education message. Supports from healthcare providers, community-based testing programs, and public health education programs are likely needed to motivate diagnostic testing among Chinese people at risk of HBV infection.

Methodological and Ethical Considerations in Research With Immigrant and Refugee Survivors of Intimate Partner Violence

To promote safe and positive health outcomes by utilizing culturally relevant evidence-based interventions for immigrant and refugee women survivors of intimate partner violence, their active participation in research is critical. With 43.6 million immigrants and refugees living in the United States, there is a need for research studies to eliminate health disparities in these populations. However, barriers to recruiting and retaining these populations in research prevent the provision of quality and culturally informed services to meet their needs. The aim of this article is to discuss the recruitment and retention strategies employed and analyze the methodological and ethical challenges in the context of the weWomen Study. The use of a multifaceted approach informed by best practices maximized recruitment efforts and active participation that generated high numbers of immigrant and refugee women participants. The study also substantiated the need for more community-based participatory approaches to engage community members in the development of culturally appropriate approaches that instill a sense of ownership over the research process. Active research participation of immigrant and refugee survivors will help investigators understand their unique needs and facilitate the implementation of targeted evidence-based interventions.

Endocrine Surgery Patients' and Providers' Perceptions of Telemedicine in the COVID Era

Background

Telemedicine has become a key modality for health care delivery during the COVID-19 pandemic, including for endocrine surgery. Little data exists on patients’ and referring endocrinologists’ perspectives of its use. The study aimed to assess and compare endocrine surgery patients’ attitudes about telemedicine to that of referring endocrinologists.

Method

Patients from a regional endocrine surgery practice and referring endocrinologists were sent surveys about their perspectives on telemedicine use.

Results

Fifty two patients responded: average age was 58.3 years; 78% were female; 33% were Black. Sixteen referring endocrinologists responded: average age was 52.4 years; 62.5% were female. Nearly all patients (92%) and providers (100%) would try telemedicine or use it again. Providers were more likely than patients to use telemedicine because of COVID-19 (100% versus 70.6%, P = 0.03). Patients were more concerned about the lack of personal connection with telemedicine than providers (60.8% versus 25.0%, P = 0.02). Endocrinologists were more interested in using telemedicine to review abnormal results (81.3% versus 35.3%, P <0.01), and more patients were specifically disinterested in reviewing abnormal results via telemedicine (54.9% versus 6.3%, P = 0.04). Patients were more interested in its use for postoperative visits (47.1% versus 0%, P <0.01). More endocrinologists were specifically disinclined to conduct new consultations with telemedicine (87.5% versus 58.8%, P <0.01).

Conclusion

Telemedicine is a mutually acceptable method for patients and their referring providers for endocrine surgery delivery, although in-person visits continue to have their place. Telemedicine use may continue to expand after the pandemic as an important point of access for endocrine surgery.

Recruitment and Retention Strategies Among Racial and Ethnic Minorities in Web-Based Intervention Trials: Retrospective Qualitative Analysis

Background

Racial and ethnic minority groups are underrepresented in health research, contributing to persistent health disparities in the United States. Identifying effective recruitment and retention strategies among minority groups and their subpopulations is an important research agenda. Web-based intervention approaches are becoming increasingly popular with the ubiquitous use of the internet. However, it is not completely clear which recruitment and retention strategies have been successful in web-based intervention trials targeting racial and ethnic minorities.

Objective

This study aims to describe lessons learned in recruiting and retaining one of the understudied ethnic minority women—Korean Americans—enrolled in a web-based intervention trial and to compare our findings with the strategies reported in relevant published web-based intervention trials.

Methods

Multiple sources of data were used to address the objectives of this study, including the study team’s meeting minutes, participant tracking and contact logs, survey reports, and postintervention interviews. In addition, an electronic search involving 2 databases (PubMed and CINAHL) was performed to identify published studies using web-based interventions. Qualitative analysis was then performed to identify common themes addressing recruitment and retention strategies across the trials using web-based intervention modalities.

Results

A total of 9 categories of recruitment and retention strategies emerged: authentic care; accommodation of time, place, and transportation; financial incentives; diversity among the study team; multiple, yet standardized modes of communication; mobilizing existing community relationships with efforts to build trust; prioritizing features of web-based intervention; combined use of web-based and direct recruitment; and self-directed web-based intervention with human support. Although all the studies included in the analysis combined multiple strategies, prioritizing features of web-based intervention or use of human support were particularly relevant for promoting recruitment and retention of racial and ethnic minorities in web-based intervention trials.

Conclusions

The growing prevalence of internet use among racial and ethnic minority populations represents an excellent opportunity to design and deliver intervention programs via the internet. Future research should explore and compare successful recruitment and retention methods among race and ethnic groups for web-based interventions.

The importance of community and culture for the recruitment, engagement, and retention of Chinese American immigrants in health interventions

Chinese Americans experience cancer health disparities throughout the entire cancer continuum. Yet, they remain underrepresented in health research in part due to barriers in recruitment, engagement, and retention. This paper describes the strategies that we devised, by drawing upon our experiences with conducting two culturally sensitive cancer intervention studies, to help researchers improve their recruitment and retention rates of Chinese Americans in health research and address the gap in knowledge on intervention research with this population. The first study assessed the efficacy, adoption, and impact of an intervention, delivered by community health workers, to improve adherence to recommended stomach cancer prevention guidelines for at-risk Chinese Americans. The second study evaluated the feasibility and preliminary efficacy of a culturally adapted version of the Expressive Helping intervention for Chinese American cancer patients and survivors. Our main recruitment strategies revolved around building community relationships, developing culturally sensitive materials, and establishing good first impressions with participants. Our main engagement and retention strategies focused on attending to cultural sensitivity, fostering relationships, and using technology. Harnessing the community's inherent strengths and prioritizing cultural understanding is crucial for culturally sensitive health research with Chinese Americans.

Recruitment of Asian Americans with Schizophrenia Spectrum Disorder for Research Participation: Barriers, Strategies, and Outcomes

Difficulty reaching Asian Americans with schizophrenia spectrum disorder has prompted mental health researchers to exclude this subpopulation from the sampling frame or enroll a comparatively smaller sample compared to other races and ethnicities with similar diagnoses. Understanding potential influences on research participation may facilitate efforts to increase the representation of this vulnerable yet underrepresented population in research. We detailed our experiences recruiting Asian Americans with schizophrenia spectrum disorder for participation in an observational study that evaluated their clinical outcomes. We applied the matching model of recruitment by identifying recruitment barriers encountered by or arising from the target group and researchers at the macro (community mental health center and academic institution), mediator (gatekeepers and research team), and micro (participant and interviewer) levels and then implementing a multilevel approach to overcoming identified obstacles. Our yearlong recruitment efforts yielded a diverse community sample (n = 75) recruited from six urban community mental health centers. Barriers to involving Asian Americans with schizophrenia spectrum disorder in research are complex and associated with being a member of a heterogeneous racial and ethnic minority group and having a serious psychiatric condition. Engaging Asian Americans with schizophrenia spectrum disorder in research is feasible if researchers devote time and resources to address barriers confronting the target group and challenges researchers encounter.

Comparison of Recruitment Strategies for Engaging Older Minority Adults: Results From Take Heart

BACKGROUND

Few published studies report lessons learned for recruiting older adults from racial/ethnic minority, low SES communities for behavioral interventions. In this article, we describe recruitment processes and results for Take Heart, a randomized controlled trial testing the effectiveness of an adapted heart disease self-management program for primarily African American, urban, low SES adults 50 years or older living in Detroit.

METHODS

Older adults were recruited via community-based (CB), electronic medical record (EMR), and in-person hospital clinic (HC) methods. Recruitment processes, demographic characteristics of enrolled participants, yield and cost, lessons learned, and best practices for each method are described.

RESULTS

Within 22 months, 1,478 potential participants were identified, 1,223 were contacted and 453 enrolled, resulting in an overall recruitment yield of 37%. The CB method had the highest yield at 49%, followed by HC at 36% and EMR at 16%. Of six CB approaches, information sessions and flyers had the highest yields at 60% and 59%, respectively. The average cost of recruiting and enrolling one participant was $142.

CONCLUSIONS

CB, EMR, and HC methods each made important contributions to reaching our recruitment goal. The CB method resulted in the highest recruitment yield, while EMR had the lowest. Face-to-face interaction with community members and hiring a community health worker were particularly useful in engaging this population. Further research is needed to confirm these findings in urban, minority, low SES populations of older adults.

Transparency, trust and minimizing burden to increase recruitment and retention in trials: a systematic review

OBJECTIVE

To describe patient perspectives on recruitment and retention in clinical trials.

STUDY DESIGN AND SETTING

Systematic review of qualitative studies that reported the perspective of adult patients with any health condition who accepted or declined to participate in clinical trials.

RESULTS

Sixty-three articles involving 1681 adult patients were included. Six themes were identified. Four themes reflected barriers: ambiguity of context and benefit - patients were unaware of the research question and felt pressured in making decisions; lacking awareness of opportunities - some believed health professionals obscured trials opportunities, or felt confused because of language barriers; wary of added burden - patients were without capacity because of sickness or competing priorities; and skepticism, fear and mistrust - patients feared loss of privacy, were suspicious of doctor's motivation, afraid of being a guinea pig, and disengaged from not knowing outcomes. Two themes captured facilitators: building confidence - patients hoped for better treatment, were supported from family members and trusted medical staff; and social gains and belonging to the community - altruism, a sense of belonging and peer encouragement motivated participation in trials.

CONCLUSION

Improving the visibility and transparency of trials, supporting informed decision making, minimizing burden, and ensuring confidence and trust may improve patient participation in trials.

Characteristics Associated with Participation in ENGAGED 2 - A Web-based Breast Cancer Risk Communication and Decision Support Trial

PURPOSE

We evaluated demographic and clinical characteristics associated with participation in a clinical trial testing the efficacy of an online tool to support breast cancer risk communication and decision support for risk mitigation to determine the generalizability of trial results.

METHODS

Eligible women were members of Kaiser Permanente Washington aged 40-69 years with a recent normal screening mammogram, heterogeneously or extremely dense breasts and a calculated risk of > 1.67% based on the Breast Cancer Surveillance Consortium 5-year breast cancer risk model. Trial outcomes were chemoprevention and breast magnetic resonance imaging by 12-months post-baseline. Women were recruited via mail with phone follow-up using plain language materials notifying them of their density status and higher than average breast cancer risk. Multivariable logistic regression calculated independent odds ratios (ORs) for associations between demographic and clinical characteristics with trial participation.

RESULTS

Of 2,569 eligible women contacted, 995 (38.7%) participated. Women with some college (OR = 1.99, 95% confidence interval [CI] 1.34-2.96) or college degree (OR = 3.35, 95% CI 2.29-4.90) were more likely to participate than high school-educated women. Race/ethnicity also was associated with participation (African-American OR = 0.50, 95% CI 0.29-0.87; Asian OR = 0.22, 95% CI 0.12-0.41). Multivariate adjusted ORs for family history of breast/ovarian cancer were not associated with trial participation.

DISCUSSION

Use of plain language and potential access to a website providing personal breast cancer risk information and education were insufficient in achieving representative participation in a breast cancer prevention trial. Additional methods of targeting and tailoring, potentially facilitated by clinical and community outreach, are needed to facilitate equitable engagement for all women.

Culturally Tailored Intervention to Promote Mammography Screening Practice Among Chinese American Women: a Systematic Review

Our review aimed to assess the effectiveness of culturally tailored intervention in mammography practice for Chinese American women. We searched the entire paper published by the Cochrane Library, PubMed, and Web of Science from inception to 17 October 2019. Moreover, we manually checked reference lists of included studies to find other potentially eligible studies. It included clinical trials published in English that evaluated the effects of culturally tailored intervention on mammography practice for Chinese American women. Finally, we involved eight studies in our review. After the intervention, the mammography intention and breast cancer-related knowledge were significantly improved. However, there was no significant impact on mammography completion rate, perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers, and Eastern cultural views of Chinese American women. The culturally tailored interventions could serve as promising approaches to improve mammography screening practice for Chinese American women, but further improvements are needed.

Barriers and Facilitators to Breast and Cervical Cancer Screening Among Immigrants in the United States

To summarize the literature on barriers and facilitators to breast and cervical cancer screening among immigrants to the US. A literature review was conducted for studies on breast and cervical cancer screening among immigrant populations. A thematic analysis of 180 studies identified a variety of barriers and facilitators to screening at the personal and system levels. Personal barriers included lack of knowledge and insurance coverage, high cost of care, and immigration status. System barriers included poor access to services, lack of interpreter services, and insensitivity to patient needs. Facilitators to screening included knowledge of disease, access to information sources, physician recommendation, and social networks. Cultural norms and resource availability at the individual and system levels influence screening among immigrants. Health insurance coverage was found to be an important predictor of preventative screening use. Future research should seek to identify the best way to address this and other barriers to cancer screening among immigrants groups.

Recruiting African Immigrant Women for Community-Based Cancer Prevention Studies: Lessons Learned from the AfroPap Study

Recruitment in research can be challenging, particularly for racial/ethnic minorities and immigrants. There remains a dearth of research identifying the health and sociocultural needs of these populations related to recruitment. To describe our experiences and lessons learned in recruiting African immigrant (AI) women for the AfroPap study, a community-based study examining correlates of cervical cancer screening behaviors. We developed several recruitment strategies in collaboration with key informants and considered published recruitment methods proven effective in immigrant populations. We also evaluated the various recruitment strategies using recruitment records and study team meeting logs. We enrolled 167 AI women in the AfroPap study. We used the following recruitment strategies: (1) mobilizing African churches; (2) utilizing word of mouth through family and friends; (3) maximizing research team's cultural competence and gender concordance; (4) promoting altruism through health education; (5) ensuring confidentiality through the consenting and data collection processes; and (6) providing options for data collection. Online recruitment via WhatsApp was an effective recruitment strategy because it built on existing information sharing norms within the community. Fear of confidentiality breaches and time constraints were the most common barriers to recruitment. We were successful in recruiting a "hard-to-reach" immigrant population in a study to understand the correlates of cervical cancer screening behaviors among AI women by using a variety of recruitment strategies. For future research involving African immigrants, using the internet and social media to recruit participants is a promising strategy to consider.

A Systematic Review of Promising Strategies of Faith-Based Cancer Education and Lifestyle Interventions Among Racial/Ethnic Minority Groups

Church-based interventions have been used to reach racial/ethnic minorities. In order to develop effective programs, we conducted a comprehensive systematic review of faith-based cancer prevention studies (2005~2016) to examine characteristics and promising strategies. Combination terms "church or faith-based or religion," "intervention or program," and "cancer education or lifestyle" were used in searching the five major databases: CINAHL; ERIC; Health Technology Assessments; MEDLINE; and PsycInfo. A total of 20 studies met study criteria. CDC's Community Guide was used to analyze and review group interventions. Analyses were organized by two racial groups: African American (AA) and Latino/Hispanic American groups. Results showed most studies reviewed focused on breast cancer alone or in combination with other cancers. Studies of Latino/Hispanic groups targeted more on uninsured, Medicare, or Medicaid individuals, whereas AA studies generally did not include specific insurance criteria. The sample sizes of the AA studies were generally larger. The majority of these studies reviewed used pre-post, posttest only with control group, or quasi-experience designs. The Health Belief Model was the most commonly used theory in both groups. Community-based participatory research and empowerment/ecological frameworks were also used frequently in the Latino/Hispanic studies. Small media and group education were the top two most popular intervention strategies in both groups. Although one-on-one strategy was used in some Latino studies, neither group used reducing client out-of-pocket costs strategy. Client reminders could also be used more in both groups as well. Current review showed church-based cancer education programs were effective in changing knowledge, but not always screening utilization. Results show faith-based cancer educational interventions are promising. To maximize intervention impact, future studies might consider using stronger study designs, incorporating a variety of proven effective strategies, including those frequently used evidence-based strategies, as well as exploring promising strategies among specific target groups.

Knowledge, attitudes, practices and perceptions of clinicians towards conducting clinical trials in an Academic Tertiary Care Center

Objectives:

To investigate the knowledge, attitudes practices and perceptions of clinicians concerning the conducting of clinical trials (CTs).

Methods:

A cross-sectional study was conducted on clinicians at King Fahad Medical City, Riyadh, Saudi Arabia. Data were collected using a self-administered questionnaire which divided into 5 sections: Section 1 covered respondents’ demographics. The other 4 sections explored respondents’ knowledge, attitudes, perceptions and practice towards conducting CTs.

Results:

A total of 316 clinicians completed the questionnaire. The majority were assistant consultants and consultants 125 (39.5%) and 108 (34.2%), respectively. One hundred sixty-nine (56%) respondents were not aware of the Declaration of Helsinki at all. Two hundred seventy-five (88.4%) respondents expressed interest in conducting CTs and 61.7% and participants showed their willingness to facilitate and assist in CTs conducted by other clinicians. Moreover, 112 (35.9%) respondents participated in CTs previously. Regarding the disadvantages in conducting CTs, participants indicated that the paperwork was complicated and they believed that they might lose patients from their clinical practice once they are recruited in CTs. Lack of research protected time for clinicians 295 (97.7%), and a shortage of clinical research coordinators 293 (97%) were the main problems reported by respondents.

Conclusions:

Although the majority of participants had an unsatisfactory level of knowledge and misperceptions about CTs, they showed an interest in and positive attitudes about conducting CTs.

Strategies to improve recruitment to randomised trials

BACKGROUND

Recruiting participants to trials can be extremely difficult. Identifying strategies that improve trial recruitment would benefit both trialists and health research.

OBJECTIVES

To quantify the effects of strategies for improving recruitment of participants to randomised trials. A secondary objective is to assess the evidence for the effect of the research setting (e.g. primary care versus secondary care) on recruitment.

SEARCH METHODS

We searched the Cochrane Methodology Review Group Specialised Register (CMR) in the Cochrane Library (July 2012, searched 11 February 2015); MEDLINE and MEDLINE In Process (OVID) (1946 to 10 February 2015); Embase (OVID) (1996 to 2015 Week 06); Science Citation Index & Social Science Citation Index (ISI) (2009 to 11 February 2015) and ERIC (EBSCO) (2009 to 11 February 2015).

SELECTION CRITERIA

Randomised and quasi-randomised trials of methods to increase recruitment to randomised trials. This includes non-healthcare studies and studies recruiting to hypothetical trials. We excluded studies aiming to increase response rates to questionnaires or trial retention and those evaluating incentives and disincentives for clinicians to recruit participants.

DATA COLLECTION AND ANALYSIS

We extracted data on: the method evaluated; country in which the study was carried out; nature of the population; nature of the study setting; nature of the study to be recruited into; randomisation or quasi-randomisation method; and numbers and proportions in each intervention group. We used a risk difference to estimate the absolute improvement and the 95% confidence interval (CI) to describe the effect in individual trials. We assessed heterogeneity between trial results. We used GRADE to judge the certainty we had in the evidence coming from each comparison.

MAIN RESULTS

We identified 68 eligible trials (24 new to this update) with more than 74,000 participants. There were 63 studies involving interventions aimed directly at trial participants, while five evaluated interventions aimed at people recruiting participants. All studies were in health care.We found 72 comparisons, but just three are supported by high-certainty evidence according to GRADE.1. Open trials rather than blinded, placebo trials. The absolute improvement was 10% (95% CI 7% to 13%).2. Telephone reminders to people who do not respond to a postal invitation. The absolute improvement was 6% (95% CI 3% to 9%). This result applies to trials that have low underlying recruitment. We are less certain for trials that start out with moderately good recruitment (i.e. over 10%).3. Using a particular, bespoke, user-testing approach to develop participant information leaflets. This method involved spending a lot of time working with the target population for recruitment to decide on the content, format and appearance of the participant information leaflet. This made little or no difference to recruitment: absolute improvement was 1% (95% CI -1% to 3%).We had moderate-certainty evidence for eight other comparisons; our confidence was reduced for most of these because the results came from a single study. Three of the methods were changes to trial management, three were changes to how potential participants received information, one was aimed at recruiters, and the last was a test of financial incentives. All of these comparisons would benefit from other researchers replicating the evaluation. There were no evaluations in paediatric trials.We had much less confidence in the other 61 comparisons because the studies had design flaws, were single studies, had very uncertain results or were hypothetical (mock) trials rather than real ones.

AUTHORS' CONCLUSIONS

The literature on interventions to improve recruitment to trials has plenty of variety but little depth. Only 3 of 72 comparisons are supported by high-certainty evidence according to GRADE: having an open trial and using telephone reminders to non-responders to postal interventions both increase recruitment; a specialised way of developing participant information leaflets had little or no effect. The methodology research community should improve the evidence base by replicating evaluations of existing strategies, rather than developing and testing new ones.

Physician Intervention and Chinese Americans' Colorectal Cancer Screening

OBJECTIVE

We conducted a cluster-randomized trial evaluating an intervention that trained Chinese-American primary care physicians to increase their Chinese patients' colorectal cancer (CRC) screening.

METHODS

Twenty-five physicians (13 randomized to the intervention arm and 12 to the control arm) and 479 of their patients (aged 50-75 and nonadherent to CRC screening guidelines) were enrolled. The intervention, guided by Social Cognitive Theory, included a communication guide and 2 in-office training sessions to enhance physicians' efficacy in com- municating CRC screening with patients. Patients' CRC screening rates (trial outcome) and rating of physician communication before intervention and at 12-month follow-up were assessed. Intention-to-treat analysis for outcome evaluation was conducted.

RESULTS

Screening rates were slightly higher in the intervention vs. the control arm (24.4% vs. 17.7%, p = .24). In post hoc analyses, intervention arm patients who perceived better communication were more likely to be screened than those who did not (OR = 1.09, 95% CI: 1.03, 1.15). This relationship was not seen in the control arm.

CONCLUSIONS

This physician-focused intervention had small, non-significant effects in increasing Chinese patients' CRC screening rates. Physician communication appeared to explain intervention efficacy. More intensive interventions are needed to enhance Chinese patients' CRC screening.

Strategies for recruiting South Asian women to cancer screening research and the lessons learnt

AIMS

The aim of this study was to describe and discuss the recruitment strategies used in a research study of cervical cancer screening among South Asian women, the challenges encountered and the lessons learnt from the experience.

BACKGROUND

Ethnic minority populations face different barriers to participating in research studies. Strategies have been developed to recruit this population to health-related research in Western countries, but there is little information about such research in the Asian region.

DESIGN

Discussion paper.

DATA SOURCES

The discussion is based on our previous experience. The source of this experience is the recruitment strategies used, their results and the challenges encountered during the process.

IMPLICATIONS FOR NURSING

Culturally, relevant strategies and maintaining good relationships with stakeholders improved participant recruitment. Familiarity with South Asians' traditional calendar - when cultural and religious festivals are held every year - would aid the setting up of appropriate schedules for participant recruitment, either before or after the periods when they cannot be reached, such as Ramadan. South Asian women are often busy with childcare and housework. This is their major responsibility in the family and any failure to fulfil such duties is a source of stress and may foster feelings of guilt. A better understanding of their daily routines is therefore important. Such information enables the establishment of daily meeting schedules to increase the success rate of recruitment.

CONCLUSION

Recruitment is a tedious process, but appropriate planning and taking account of cultural and religious practices and daily schedules will help to improve its rate of success.

Conducting Cancer Research among Culturally and Linguistically Diverse Groups in Australia: A Reflection on Challenges and Strategies

Background

While effort has been made to include minority groups in cancer studies in Western countries, overseas experience indicates that recruiting immigrant members to participate in cancer research is challenging. The aim of the paper is to set out the challenges and strategies needed to ensure the success of cancer research among culturally and linguistically diverse (CALD) groups in Australia.

Discussion

Author suggested that partnership with ethnic community organization, research team, research setting and data collection methods, access to national data in cancer register, the informed consent process, and resources management are important elements to ensure the success of cancer research among CALD groups.

Summary

The paper provides health care professionals with insight into methodological and practical issues needed to plan and conduct cancer research among CALD populations not only in Australia but also other Western countries, where numbers of minority groups are increasing significantly.

Recruiting Chinese- and Korean-Americans in Cancer Survivorship Research: Challenges and Lessons Learned

This paper describes Asian-American recruitment experiences using data from the cancer survivorship study involving Chinese- and Korean-American breast cancer survivors specifically. The article discusses challenges to the successful recruitment of Asian-American populations for cancer survivorship research and provides recommendations for future recruitment efforts. The study investigated the role of family communication in coping and quality of life for survivors from Chinese- and Korean-American groups diagnosed with breast cancer. Participants were primarily recruited through cancer registries and community outreach. A total of 157 breast cancer survivors (86 Chinese-Americans and 71 Korean-Americans) completed the final survey, yielding a final response rate of 62.8 % of the accessible samples. Chinese-Americans were more likely to agree to participate but less frequently completed the survey, and Korean-Americans were more likely to refuse to participate. Common reasons for refusal were "too busy or too painful to recall," followed by "not interested," "too old," "distrust of the research," or "health issue." Participants were more likely to be young and Korean-American compared to non-participants. Cultural and linguistic barriers, distrust, and lack of awareness about cancer research should be considered to recruit more Asian-American cancer survivors. Community participatory research is required to ensure participation by sufficient numbers of ethnic minorities in cancer survivorship research.

Hepatitis B screening practice among older Chinese in the Greater Washington, DC, area

OBJECTIVES

Older Chinese Americans are at greater risk of contracting hepatitis B virus (HBV) because they were born before the implementation of universal childhood vaccination policies. This study examined the prevalence of HBV screening, test results, and predictors of HBV screening among older Chinese.

METHODS

Two hundred fifty-two Chinese immigrants (older than 50 years) recruited from Chinese-speaking physicians' offices in the Washington, DC, area participated in a cancer screening questionnaire. Descriptive statistics and hierarchical logistic regressions were conducted.

RESULTS

Among the 164 participants (65%) who underwent HBV screening, 66% reported that they were susceptible to HBV infection. Stronger self-care beliefs, longer US residency, lower HBV knowledge, and lack of physician recommendations were independently and negatively associated with HBV screening.

CONCLUSIONS

Many older Chinese did not adhere to HBV screening guidelines because of cultural views and information deficiency. Culturally appropriate interventions aimed to enhance their knowledge and communication with physicians about HBV are needed for promoting screening.

Challenges in recruitment to a randomized controlled study of cardiovascular disease reduction in sleep apnea: an analysis of alternative strategies

STUDY OBJECTIVES

A challenge in conducting randomized controlled trials of sleep apnea is the timely recruitment of participants to active and control arms. This study assesses the costs and efficiencies of alternative recruitment methods.

DESIGN

Analysis of recruitment data from the Best Apnea Intervention in Research planning study.

SETTING

Sleep clinics and cardiology practices.

PARTICIPANTS

One hundred forty-eight individuals with an apnea-hypopnea index > 15 and cardiovascular (CV) risk factors randomized from a pool of more than 30,000 potentially eligible patients.

INTERVENTIONS

Comparisons: (1) modes of recruitment: face-to-face (F2F) recruitment versus mail-based recruitment (MBR); (2) recruitment source (sleep versus cardiology clinics).

MEASUREMENTS AND RESULTS

Recruitment yield was defined as the ratio of the number of subjects randomized to the number of screened records. Recruitment costs were estimated based on staff time. Of the 148 randomized subjects, 25 were recruited from sleep clinics using F2F recruitment and 123 were recruited from cardiology using a F2F (n = 35) or MBR (n = 88) strategy. F2F recruitment yields were 0.17% and 0.30% for sleep versus cardiology sources, respectively (P = 0.04). A comparison of F2F to MBR showed recruitment yields of 1.11% and 0.90% and costs per randomized subject of $2,139 and $647, respectively.

CONCLUSIONS

Large resources may be needed to meet the recruitment goals of sleep apnea intervention trials. Recruitment source and mode influence efficiencies. For a trial comparing active versus sham continuous positive airway pressure in patients with CV risk factors, recruiting from cardiology was more efficient than from sleep clinics. MBR was three times less costly than F2F recruitment.
