The effect of physician permission versus notification on research recruitment through cancer registries (United States)

Effectiveness and Cost of Recruiting Participants to a Research Registry Using an Emergency Department Research Associate Program

We identified a novel way to recruit participants into a research registry by using an Emergency Department Research Associate (EDRA) Program. Research associates working in the Emergency Department at Strong Memorial Hospital approached patients and family members to enroll into the University of Rochester Research Participant Registry and for http://ResearchMatch.org. We found that 73% of individuals (574/781) approached agreed to register for either one or both registries. Those who registered were more diverse than individuals who registered through other methods. Overall, using EDRAs to enroll adult patients and their family members is an effective method for growing research participant registries.

Patient perspectives on use of electronic health records for research recruitment

BACKGROUND

EHR phenotyping offers the ability to rapidly assemble a precisely defined cohort of patients prescreened for eligibility to participate in health-related research. Even so, stakeholders in the process must still contend with the practical and ethical challenges associated with research recruitment. Patient perspectives on these matters are particularly important given that the success of research recruitment depends on patients' willingness to participate.

METHODS

We conducted 15 focus groups (n = 110 participants) in four counties in diverse regions of the southeastern US: Appalachia, the Mississippi Delta, and the Piedmont area of North Carolina. Based on a hypothetical study of a behavioral intervention for type 2 diabetes, we asked about the acceptability and appropriateness of direct investigator versus physician-mediated contact with patients for research recruitment, and whether patients should be asked to opt in or opt out of further contact in response to recruitment letters.

RESULTS

For initial contact, nearly all participants said it would be acceptable for researchers to contact patients directly and three-fourths said that it would be acceptable for researchers to contact patients through their physicians. When we asked which would be most appropriate, a substantial majority chose direct contact. Themes that arose in the discussion included trust and transparency, decision-making power, the effect on research, and the effect on patient care. For response expectations, the vast majority of participants said both opt-in and opt-out would be acceptable-typically finding neither especially problematic and noting that both afford patients the opportunity to make their own decisions.

CONCLUSIONS

External validity relies heavily on researchers' success enrolling eligible patients and failure to reach accrual targets is a costly and common barrier to advancing scientific knowledge. Our results suggest that patients recognize multiple advantages and disadvantages of different research recruitment strategies and place value on the implications not just for themselves, but also for researchers and healthcare providers. Our findings, including rich qualitative detail, contribute to the body of empirical and ethical literature on improving research recruitment and suggest specific ways forward as well as important areas for future research.

A survey of practices for the use of electronic health records to support research recruitment

Electronic health records (EHRs) provide great promise for identifying cohorts and enhancing research recruitment. Such approaches are sorely needed, but there are few descriptions in the literature of prevailing practices to guide their use. A multidisciplinary workgroup was formed to examine current practices in the use of EHRs in recruitment and to propose future directions. The group surveyed consortium members regarding current practices. Over 98% of the Clinical and Translational Science Award Consortium responded to the survey. Brokered and self-service data warehouse access are in early or full operation at 94% and 92% of institutions, respectively, whereas, EHR alerts to providers and to research teams are at 45% and 48%, respectively, and use of patient portals for research is at 20%. However, these percentages increase significantly to 88% and above if planning and exploratory work were considered cumulatively. For most approaches, implementation reflected perceived demand. Regulatory and workflow processes were similarly varied, and many respondents described substantive restrictions arising from logistical constraints and limitations on collaboration and data sharing. Survey results reflect wide variation in implementation and approach, and point to strong need for comparative research and development of best practices to protect patients and facilitate interinstitutional collaboration and multisite research.

Recruiting families at risk for hereditary breast and ovarian cancer from a statewide cancer registry: a methodological study

PURPOSE

Cancer genetic services (counseling/testing) are recommended for women diagnosed with breast cancer younger than 45 years old (young breast cancer survivors-YBCS) and at-risk relatives. We present recruitment of YBCS, identification and recruitment of at-risk relatives, and YBCS willingness to contact their cancer-free, female relatives.

METHODS

A random sample of 3,000 YBCS, stratified by race (Black vs. White/Other), was identified through a population-based cancer registry and recruited in a randomized trial designed to increase use of cancer genetic services. Baseline demographic, clinical, and family characteristics, and variables associated with the Theory of Planned Behavior (TPB) were assessed as predictors of YBCS' willingness to contact at-risk relatives.

RESULTS

The 883 YBCS (33.2% response rate; 40% Black) who returned a survey had 1,875 at-risk relatives and were willing to contact 1,360 (72.5%). From 853 invited at-risk relatives (up to two relatives per YBCS), 442 responded (51.6% response rate). YBCS with larger families, with a previous diagnosis of depression, and motivated to comply with recommendations from family members were likely to contact a greater number of relatives. Black YBCS were more likely to contact younger relatives and those living further than 50 miles compared to White/Other YBCS.

CONCLUSION

It is feasible to recruit diverse families at risk for hereditary cancer from a population-based cancer registry. This recruitment approach can be used as a paradigm for harmonizing processes and increasing internal and external validity of large-scale public health genomic initiatives in the era of precision medicine.

The National Cancer Institute-American Society of Clinical Oncology Cancer Trial Accrual Symposium: summary and recommendations

INTRODUCTION

Many challenges to clinical trial accrual exist, resulting in studies with inadequate enrollment and potentially delaying answers to important scientific and clinical questions.

METHODS

The National Cancer Institute (NCI) and the American Society of Clinical Oncology (ASCO) cosponsored the Cancer Trial Accrual Symposium: Science and Solutions on April 29-30, 2010 to examine the state of accrual science related to patient/community, physician/provider, and site/organizational influences, and identify new interventions to facilitate clinical trial enrollment. The symposium featured breakout sessions, plenary sessions, and a poster session including 100 abstracts. Among the 358 attendees were clinical investigators, researchers of accrual strategies, research administrators, nurses, research coordinators, patient advocates, and educators. A bibliography of the accrual literature in these three major areas was provided to participants in advance of the meeting. After the symposium, the literature in these areas was revisited to determine if the symposium recommendations remained relevant within the context of the current literature.

RESULTS

Few rigorously conducted studies have tested interventions to address challenges to clinical trials accrual. Attendees developed recommendations for improving accrual and identified priority areas for future accrual research at the patient/community, physician/provider, and site/organizational levels. Current literature continues to support the symposium recommendations.

CONCLUSIONS

A combination of approaches addressing both the multifactorial nature of accrual challenges and the characteristics of the target population may be needed to improve accrual to cancer clinical trials. Recommendations for best practices and for future research developed from the symposium are provided.

Recruitment of representative samples for low incidence cancer populations: do registries deliver?

Background

Recruiting large and representative samples of adolescent and young adult (AYA) cancer survivors is important for gaining accurate data regarding the prevalence of unmet needs in this population. This study aimed to describe recruitment rates for AYAs recruited through a cancer registry with particular focus on: active clinician consent protocols, reasons for clinicians not providing consent and the representativeness of the final sample.

Methods

Adolescents and young adults aged 14 to19 years inclusive and listed on the cancer registry from January 1 2002 to December 31 2007 were identified. An active clinician consent protocol was used whereby the registry sent a letter to AYAs primary treating clinicians requesting permission to contact the survivors. The registry then sent survivors who received their clinician's consent a letter seeking permission to forward their contact details to the research team. Consenting AYAs were sent a questionnaire which assessed their unmet needs.

Results

The overall consent rate for AYAs identified as eligible by the registry was 7.8%. Of the 411 potentially eligible survivors identified, just over half (n = 232, 56%) received their clinician's consent to be contacted. Of those 232 AYAs, 65% were unable to be contacted. Only 18 AYAs (7.8%) refused permission for their contact details to be passed on to the research team. Of the 64 young people who agreed to be contacted, 50% (n = 32) completed the questionnaire.

Conclusions

Cancer registries which employ active clinician consent protocols may not be appropriate for recruiting large, representative samples of AYAs diagnosed with cancer. Given that AYA cancer survivors are highly mobile, alternative methods such as treatment centre and clinic based recruitment may need to be considered.

A cost-effectiveness analysis of subject recruitment strategies in the HIPAA era: results from a colorectal cancer screening adherence trial

BACKGROUND

Changes in regulatory standards that restrict use of identifiable health information can reduce patient recruitment to clinical trials and increase recruitment costs.

PURPOSE

To compare subject accrual rates and costs of three recruitment strategies that comply with new regulatory standards within the context of a clinical trial evaluating the impact of shared decision-making on colorectal cancer screening adherence.

METHODS

Sequential cohorts of English-speaking, average-risk patients due for colorectal cancer screening were allocated to one of three recruitment strategies: (1) a provider-initiated electronic 'opt-in' referral (Click) method; (2) a provider-mediated 'opt-in' referral letter (Letter) method; and (3) an investigator-initiated direct contact 'opt-out' (Call) method.

RESULTS

During distinct 6-month recruitment periods between March 2005 and April 2006, 100 potential subjects were identified using the Click method, 847 by the Letter method, and 758 by the Call method. After excluding ineligible prescreened patients, accrual rates were higher for the Call method (188 of 531 [35.4%]) than either the Click (12 of 72 [16.7%]; p = 0.002) or Letter (17 of 816 [2.1%]; p < 0.001) methods. The average cost per patient enrolled for the Call ($156) method was competitive with the Click ($129) and substantially lower than the Letter ($1967) methods; the Call method was least expensive if combined with automated patient identification ($99). Data extrapolation suggest it would take 2.4 years at an overall cost of $138,518 to recruit a target sample of 900 patients by the Call method, 40.5 years at $62,419 for the Click method and 27.9 years at $1,737,757 for the Letter method.

LIMITATIONS

The study was nonrandomized and findings may not be generalizable to other research settings.

CONCLUSION

The investigator-initiated direct contact 'opt-out' strategy is significantly more cost-effective and feasible than provider-initiated and provider-mediated 'opt-in' strategies for patient recruitment to clinical trials.

Race, healthcare access and physician trust among prostate cancer patients

OBJECTIVE

To study the effect of healthcare access and other characteristics on physician trust among black and white prostate cancer patients.

METHODS

A three-timepoint follow-up telephone survey after cancer diagnosis was conducted. This study analyzed data on 474 patients and their 1,320 interviews over three time periods.

RESULTS

Among other subpopulations, black patients who delayed seeking care had physician trust levels that were far lower than that of both Caucasians as well as that of the black patients overall. Black patients had greater variability in their levels of physician trust compared to their white counterparts.

CONCLUSIONS

Both race and access are important in explaining overall lower levels and greater variability in physician trust among black prostate cancer patients. Access barriers among black patients may spill over to the clinical encounter in the form of less physician trust, potentially contributing to racial disparities in treatment received and subsequent outcomes. Policy efforts to address the racial disparities in prostate cancer should prioritize improving healthcare access among minority groups.

Differences in baseline characteristics and outcomes at 1- and 2-year follow-up of cancer survivors accrued via self-referral versus cancer registry in the FRESH START Diet and exercise trial

Participant accrual to research studies is a challenge; oftentimes, advertisements are used to supplement cases ascertained through clinic caseloads and cancer registries. It is unknown, however, if cases ascertained through these two sources differ. In this study, we compared self-referred (n = 209) and registry-ascertained (n = 334) participants enrolled in FRESH START, a randomized controlled trial promoting a healthy diet and increased exercise among breast and prostate cancer survivors. The two groups were compared on baseline characteristics, adherence, attrition, and outcomes by study arm. Compared with participants enrolled from registries, self-referrals were significantly younger (54.1 +/- 10.4 versus 58.7 +/- 10.7 years), more likely to have later-stage disease and to have received chemotherapy (40% versus 19%), and more likely to report "fighting spirit" coping styles (50% versus 30%), lower quality-of-life (88.2 +/- 15.1 versus 92.0 +/- 12.9), fewer comorbid conditions (1.87 +/- 1.60 versus 2.24 +/- 1.78), and lower consumption of five or more daily servings of fruits and vegetables (35% versus 45%; P values <0.05). Although no differences in behavior change were observed between self-referred and registry-ascertained cases assigned to the tailored intervention arm, this was not the case within the attention control arm. Among those who received the attention control intervention of standardized materials in the public domain, self-referred versus registry-ascertained participants showed significantly greater increases in exercise at 1-year follow-up and significantly greater increases in fruit and vegetable consumption at both 1- and 2-year follow-up (P values <0.05). Several differences exist between self-referred and registry-ascertained participants, including motivation to respond to standardized educational materials, which appears significantly greater in self-referred populations.
