Improving enrollment in cancer clinical trials

'Just one interview': making visible the hidden workload associated with qualitative research

BACKGROUND

Appropriate costing and allocation of resources is vital to ensure that recruitment to a study is achieved on time and on target. However, there is little guidance concerning the workload associated with qualitative research.

AIM

To review the planned versus actual workloads in a qualitative sub-study following elective cardiac surgery in children.

DISCUSSION

Parents of children approached for a clinical trial were invited to participate in a semi-structured interview to explore their views about making decisions concerning their children's participation in the trial. A workload audit was conducted using anticipated points of contact with participants, and the duration of activities identified in the protocol and Health Research Authority statement of activities; these were compared with timed activities documented by the research team.

CONCLUSION

The current system did not anticipate or capture the workload associated with conducting a relatively straightforward qualitative sub-study of a clinical trial with a research-engaged patient group.

IMPLICATIONS FOR PRACTICE

Understanding the hidden workload associated with qualitative research is vital in ensuring that project timelines, recruitment targets and funding for research staff are realistic.

Clinical research nurses' perceptions of the unique needs of people of color for successful recruitment to cancer clinical trials

BACKGROUND

Clinical trials (CTs) test new medical products for safety and effectiveness. Despite federal policy aimed at generating greater inclusivity of people of color (POC) in CTs, disparity in (CT) enrollment persists. Non-Hispanic White patients comprise the majority of CT participants while Black and Hispanic patient participation has declined over the past decade. The scope of Clinical Research Nurses (CRNs) includes recruitment of participants for CTs. The aim of this phenomenological study was to describe adult oncology CRNs' lived experiences of recruiting POC cancer patients to participate in CTs. The first paper for this study identified three major themes regarding how CRNs view their role in caring for POC considering or enrolling onto cancer clinical trials (CCTs): CRNs act as advocates, care coordinators and educators. This paper focuses on two additional major themes regarding how CRNs view the unique needs of POC in clinical research: establishing and maintaining trusting relationships and recruitment infrastructure.

METHODS

Nineteen nurses participated in semi-structured one-to-one interviews and data analysis was based on Colaizzi's method.

RESULTS

CRNs described a history of past research injustices, disparate access to care, inadequate cultural training, a physician-driven recruitment structure and provider-based implicit biases that hinder POC enrollment in CTs.

CONCLUSION

Diversity in CCT enrollment requires CRNs to establish trust with POC, advocate for POC when implicit biases are observed and become competent practitioners of culturally sensitive care. Further, meaningful policy change at both federal and organizational levels must occur to ensure equitable access to novel cancer therapies.

A Survey of Resources and Nursing Workforce for Clinical Research Delivery in Paediatric Intensive Care Within the UK / Ireland

Introduction

Clinical research within Paediatric Intensive Care (PICU) is necessary to reduce morbidity and mortality associated within this resource-intensive environment. With UK PICUs encouraged to be research-active there was a drive to understand how centres support research delivery.

Aim

To identify the research workforce available within UK/Ireland PICUs to support clinical research delivery.

Method

An electronic survey, endorsed by the Paediatric Critical Care Society (PCCS), was designed and reported in accordance with CHERRIES guidelines. The survey was distributed by email to all UK/Ireland Nurse Managers and Medical/ Nursing Research leads, aiming for one response per site during the period of April-June 2021. Only one response per site was included in analysis.

Results

44 responses were received, representing 24/30 UK/Ireland sites (80% response rate). Responses from n = 21/30 units are included (three excluded for insufficient data). 90% (n = 19/21) units were research active, although only 52% (n = 11) had permanent research roles funded within their staffing establishment. The majority of units (n = 18, 86%) had less than two WTE research nurses. Resources were felt to be sufficient for current research delivery by 43% of units (n = 9), but this confidence diminished to 19% (n = 4) when considering their ability to support future research. The top barriers to research conduct were insufficiently funded/unfunded studies (52%; n = 11), clinical staff too busy to support research activity (52%; n = 11) and short-term/fixed-term contracts for research staff (38%; n = 8).

Conclusion

Despite the perceived importance of research and 90% of responding UK/Ireland PICUs being research active, the majority have limited resources to support research delivery. This has implications for their ability to participate in future multi-centre trials and opportunities to support the development of future medical/nursing clinical academics. Further work is required to identify optimum models of clinical research delivery.

The role of clinical research nurses in minority recruitment to cancer clinical trials

Clinical trials (CTs) are the established research mechanism designed to examine how new medical therapies are tested for safety and effectiveness. Specifically, non-Hispanic White patients still account for most CT participants and Black patient participation has declined over the past decade. Clinical Research Nurses (CRNs) whose scope of practice includes the recruitment of participants for CTs, have the potential to significantly increase minority patients participation in cancer clinical trials (CCTs). The aim of this phenomenological study was to describe adult oncology CRNs' lived experiences of recruiting minority cancer patients to participate in CTs. A total of 19 nurses participated in semi-structured one-to-one interviews and data analysis was based on Colaizzi's method. The role of CRNs was described as advocates who coordinate care, establish trust, and provide education for CT patients within physician-driven recruitment structures. The CRN's role was also described as self-taught or learn on the go with no formalized recruitment training and lack of robust cultural training. To achieve diverse patient enrollment in CCTs, CRNs and study staff need to receive training on culturally competent clinical research care and the diversity of CRNs and study teams must be increased. Further, meaningful federal and hospital policy change must occur so that minority patients have equitable access to novel cancer therapies and the role of the CRN is delineated from other healthcare staff to optimize research patient care.

Perceptions of Cancer Clinical Research Among African American Men in North Carolina

ACKNOWLEDGEMENTS

The authors are grateful to the men and women who participated in our Focus Groups and shared with us their very personal cancer experience. Their insight is valuable, and will inform and improve cancer care for future generations. The authors thank the Greensboro area Community Research Advocates - especially April Durr, Elvira Mebane, Marie McAdoo, Kathy Norcott, and Cindy Taylor - who assisted in the conduct of the study, including interpretation of results. They also thank Gratia Wright of First Research Group for her expertise in moderating and executing all of the focus groups, and Lindsey Haynes-Maslow for her assistance in responding to reviewer comments. The study was funded as a part of the Carolina Community Network program, funded by a grant from the National Cancer Institute (U01-CA114629). This study was reviewed and approved by the Institutional Review Board (IRB) at the University of North Carolina at Chapel Hill.

OBJECTIVE

The problem of cancer health disparities is substantial. Clinical trials are widely advocated as a means of reducing disparities and bringing state-of-the-art care to the broader community, where most cancer care is delivered. This study sought to develop a better understanding of why disproportionately few African American men enroll in clinical trials given their substantial cancer burden.

DESIGN

This study applied community-based participatory research (CBPR) methods to design and conduct four focus groups of African American male cancer survivors and their caregivers in North Carolina.

RESULTS

Among major themes, participants expressed confusion about the relationship between clinical trials, treatment, and research: signifying patient confusion and misinterpretation of common clinical trial terminology. Social norms including gender barriers and generational differences remain problematic; participants often reported that men do not talk about health issues, are unwilling to go to the doctor, and exhibit misapprehension and distrust regarding trials. Participants perceived this misunderstanding as detrimental to community health and expressed the need for more clarity in clinical trials information and a more fundamental social openness and communication about cancer detection and treatment.

CONCLUSION

Findings indicate the importance of clinical trial education in both traditional provider referral to trials and also in general patient navigation. To dispel pervasive misapprehension regarding placebos, clinical trial information should emphasize the role of standard care in modern cancer treatment trials. Many participants described willingness to participate in a trial upon physician recommendation, suggesting merit in improving patient-physician communication through culturally competent terminology and trial referral systems.

Researchers' and clinicians' perceptions of recruiting participants to clinical research: a thematic meta-synthesis

Background

Recruiting the desired number of research participants is frequently problematic with resulting financial and clinical implications. The views of individuals responsible for participant recruitment have not been previously reviewed. This systematic review and thematic meta-synthesis explores researchers’ and clinicians’ experiences and perceptions of recruiting participants to clinical research, with the aim of informing improved recruitment systems and strategies.

Methods

Studies published between January 1995 and May 2013 were identified from: Ovid MEDLINE, Ovid EMBASE, Ovid PSYCHINFO, ASSIA, British Nursing Index, Scopus, Web of Science, CINAHL and PubMed. Included studies were original peer reviewed research, with qualitative methodologies and an aim of exploring the views of clinicians and/or researchers on recruitment to clinical research. Studies discussing the recruitment of patients unable to give informed consent were excluded. The findings sections of the relevant studies were free coded to identify key concepts which were grouped into hierarchical themes. The quality of the identified studies was assessed and the relative contribution of each paper was checked to ensure individual studies did not dominate in any theme.

Results

Eighteen relevant papers were identified which examined the views of researchers and clinicians in 10 clinical specialties. Five main themes emerged: building a research community, securing resources, the nature of research, professional identities and recruitment strategies. The views of researchers and clinicians were similar, although the role of ‘researcher’ was inconsistently defined.

Conclusions

The general experience of recruiting participants to clinical research was one of competition and compromise. Competition arose over funding, staffing and participants, and between clinical and research responsibilities. Compromise was needed to create study designs that were acceptable to patients, clinicians and researchers. Forging relationships between clinical and research teams featured extensively, however the involvement of patients and the public within the research community was rarely discussed.

Recommendations for enhancing clinical trials education: a review of the literature

This study aims to apply the evidence-based practice (EBP) process to determine the factors that influence patients' understanding of, participation in, and satisfaction with clinical trials, the informed consent process, and treatment decisions and to make recommendations for improving clinical trials education. Beginning with evidence retrieval, the authors identified key search terms and searched MEDLINE--Ovid, MEDLINE--PubMed, and the Cumulative Index to Nursing and Allied Health Literature to identify articles published between July 2001 and July 2006 that highlighted clinical trials education. The articles were reviewed for clinical trials patient education information, clinician methods of communicating clinical trial information to patients, and patient satisfaction with the clinical trials process, including the informed consent process. As a result, practice changes were recommended for the patient/family, staff/community, and institution. From the literature review, 81 articles were identified. Recurring themes included decision-making, patient education, staff education, and pediatrics. Most articles focused on methods and strategies aimed at improving education at the patient/family, staff/community, and institutional levels. The issues surrounding clinical trial education are complex due to multiple variables interfering with poor patient understanding of, participation in, and satisfaction with clinical trial treatment decisions. On the basis of our findings, we recommend that clinicians involved in educating patients, families, staff, and communities about clinical trials have an awareness of and understanding for very complex issues.

Physical activity, weight control, and breast cancer risk and survival: clinical trial rationale and design considerations

Substantial observational epidemiological evidence exists that physical activity and weight control are associated with decreased risk of postmenopausal breast cancer. Uncertainty remains regarding several aspects of these associations, including the effect of possible confounding factors on these associations. We present the rationale and design for two randomized controlled trials that can help resolve this uncertainty. In a 5-year prevention trial conducted among women at high risk of breast cancer, the primary endpoint would be breast cancer incidence. For a comparable survivorship trial, the primary endpoint would be the disease-free interval and secondary endpoints would be breast cancer recurrence-free interval, second primary breast cancer, and total invasive plus in situ breast cancer. A set of inclusion and exclusion criteria is proposed for both trials. Intervention goals are the same for both trials. Goals for the weight control intervention would be, for women whose body mass index (BMI) is greater than 25 kg/m(2), to lose 10% of body weight and, for women whose BMI is less than or equal to 25 kg/m(2), to avoid weight gain. The goal for the physical activity intervention would be to achieve and maintain regular participation in a moderate-intensity physical activity program for a total of 150-225 minutes over at least 5 days per week. Sample size calculations are based on alternative assumptions about hazard ratio, adherence, follow-up duration, and power and are presented for the primary prevention and survivorship trials. Although both studies could enhance our understanding of breast cancer etiology and benefit public health, practical considerations, including smaller sample size, ease of recruitment, and reduced likelihood of early termination, favor the survivorship trial at this time.

Cumulative recruitment experience in two large single-center randomized, controlled clinical trials

BACKGROUND

Trial recruitment is challenging for researchers, who frequently overestimate the pool of qualified, willing participants. Little has been written about recruitment and the comparative success of recruitment strategies. We describe one center's experience with recruitment in two regional single-center clinical trials with a combined total of 1971 participants.

METHODS

The heart failure trial was conducted between 1999 and 2003. The asthma trial was performed between 2003 and 2006. Trial databases were queried for referral source of each individual. Data were analyzed for effectiveness of referral source using three measures: percentage of enrollment due to that source, subject commitment to the trial (retention rate), and economics (cost per enrollee).

RESULTS

47.8% of CHF enrollees came from computer-generated lists or from healthcare provider referrals. Average marketing cost for enrollees and completers was $29.20 and $41.96 respectively. The most economical marketing strategy was self-referral in response to flyers. Most asthma participants (53.5%) were referred from healthcare providers, mailings to lists from local healthcare institutions, or self-referred in response to flyers. Average marketing cost for enrollees and completers was $20.44 and $38.10 respectively. The most economical marketing strategy was patient mailings. Retention rates were not markedly different among referral sources in either trial.

CONCLUSION

In order to be considered effective, a recruitment strategy must demonstrate a balance between response to recruitment, retention rates, and economics. Despite the differences between these two clinical trials, the most effective recruitment strategies in both trials were mailings to locally-generated, targeted lists, and referrals from healthcare providers.

Lifestyle interventions in cancer survivors: designing programs that meet the needs of this vulnerable and growing population

In the world today, there are roughly 25 million cancer survivors. Although the increasing numbers of survivors testifies to the success of early detection and treatment, there is a downside. Cancer survivors are at increased risk for second cancers, other forms of comorbidity (e.g., cardiovascular disease, diabetes, osteoporosis), and functional decline. Lifestyle factors, such as a healthy diet, regular exercise, and smoking cessation may prevent these conditions and improve survivors' quality of life. Data also are accumulating to suggest that healthful lifestyle practices and successful weight management may prevent progressive or recurrent disease. Previous surveys conducted among both adult and pediatric cancer survivors indicate that most survivors have high levels of interest in diet and exercise interventions. Additionally, survivors who smoke report high levels of interest in interventions aimed at smoking cessation. Many factors, such as intervention timing and duration and channels of delivery, must be carefully considered in developing interventions that best meet the needs of this vulnerable population. Total transparency also is necessary in reporting the results of trials to ensure the inclusion of information regarding proportional accrual, attrition, and study sample sociodemographic characteristics to move toward the development of interventions most likely to gain broad-scale acceptance and adherence. Home-based interventions that rely on telephone counseling, mailed materials, or computer-assisted approaches offer promising means of reaching the geographically dispersed population of cancer survivors. More research is necessary to develop interventions that can reach and effectively promote long-term behavior change in this ever-increasing population.

Factors influencing inclusion of patients with malignancies in clinical trials

Participation in clinical trials remains low and is a central issue in oncology. The authors identified, through a systematic review, 75 papers published up to August 2004 that report barriers to recruitment of patients in clinical trials. These barriers range from patient preference and concern about information/consent to clinical problems with protocols. Strategies to overcome barriers on the part of patients and clinicians are needed and should be carefully evaluated. Thirty-three (44%) papers reported factors related to patients as influencing the inclusion of patients, 28 (37%) reported clinician's related factors, and 37 (49%) other factors from either specific groups of patients (30 papers, 40%) and/or other scopes (13 papers, 17%). No differences in prevalence were found between papers dedicated to hematologic malignancies and solid tumors. Factors related to clinicians as influential were more frequently reported before 1995 (70%) than thereafter (25%; P = 0.0009). Reporting specific groups of patients as influential was more frequent in North American articles (50%) than in others (14%, P = 0.008). Patients' barriers included mostly patient preference (12 papers), concern about information and/or consent (11 papers), worry about uncertainty (7 papers), and/or relationship with medical team (7 papers). Concerning clinicians, incompatibility of protocol with normal practice (nine papers), problems in complying with the protocol (eight papers), and/or consent procedure (eight papers) were the most reported factors. The remaining factors mostly relied on specific groups of patients (30 papers), notably age of patients (18 papers) and/or minority population (11 papers, all from the USA). Strategies to overcome these barriers are needed and should be carefully evaluated.
