Strategies for Successful Recruitment of Pregnant Patients Into Clinical Trials.

ABSTRACT: Clinical research in the pregnant population allows for delivery of quality, evidence-based care in obstetrics. However, in recent years, the field of obstetrics has faced severe challenges in the recruitment of the pregnant population into clinical trials, a struggle also shared by several other medical disciplines. We candidly describe our failure to recruit a healthy population of overweight and obese pregnant women in their first trimester. We were then able to glean unsuccessful and successful recruitment approaches and improve our recruitment effort by autopsy of failed strategies and with guidance from a survey disseminated to improve our understanding of community feelings about participating in research while pregnant. These "lessons learned" taught us that active recruitment within this population is a necessity; that is, direct (face-to-face discussions at obstetric appointments) compared with indirect (flyers and general emails) modalities and that prenatal care provider support of the proposed research study is vital to a patient's willingness to participate. By implementation of "lessons learned," we describe how we successfully recruited a similar pregnant population 1 year later. The Clinical Trials related to our article are as follows: 1) Expecting Success: NCT01610752, https://clinicaltrials.gov/ct2/show/NCT01610752; 2) MomEE: NCT01954342, https://clinicaltrials.gov/ct2/show/NCT01954342; and 3) Participate While Pregnant Survey: NCT02699632, https://clinicaltrials.gov/ct2/show/NCT02699632.

Project description:IntroductionRecruitment of sufficient patients with Parkinson disease into clinical trials is a barrier to successful, timely study completion. Non-pharmacologic studies have shown to be even more challenging for recruitment, despite some studies focusing on de novo Parkinson disease populations. This paper describes successful recruitment techniques from a randomized exercise clinical trial in Parkinson disease.MethodsSeveral recruitment strategies were used to enroll de novo patients with Parkinson disease into a year-long clinical trial. Strategies focused on infrastructure included fast-track clinic scheduling, weekly research meetings, an established clinical repository, real-time clinic recruitment, and outreach to the community. The nature of the study facilitated recruitment by offering a wait-listed control group, exercise at a local fitness center with a paid membership, and collection of data by shipping equipment foregoing some visits. An experienced nurse study coordinator involved in recruitment and training of the principal investigator in recruitment of minorities enhanced overall recruitment. Finally, the patient population chosen for this study, patients with de novo Parkinson disease, may be more likely to enroll in an exercise study than patients with later stage disease.ResultsSeventy-six patients with de novo Parkinson disease were successfully enrolled into the exercise clinical trial from a single site.ConclusionTargeted recruitment strategies were successful in this study. Additional modifications to the study protocol, such as eliminating treadmill stress tests before randomization, travel to an urban downtown location for study visits, and a relatively healthy Parkinson disease population, may also have impacted this study. These strategies could all be adopted for other studies in Parkinson disease, neurodegenerative diseases, or other chronic disorders.Trial registrationClinicaltrials.gov, NCT01506479 .

Project description:BackgroundRecruitment of participants into randomised controlled trials (RCTs) is critical for successful trial conduct. Although there have been two previous systematic reviews on related topics, the results (which identified specific interventions) were inconclusive and not generalizable. The aim of our study was to evaluate the relative effectiveness of recruitment strategies for participation in RCTs.Methods and findingsA systematic review, using the PRISMA guideline for reporting of systematic reviews, that compared methods of recruiting individual study participants into an actual or mock RCT were included. We searched MEDLINE, Embase, The Cochrane Library, and reference lists of relevant studies. From over 16,000 titles or abstracts reviewed, 396 papers were retrieved and 37 studies were included, in which 18,812 of at least 59,354 people approached agreed to participate in a clinical RCT. Recruitment strategies were broadly divided into four groups: novel trial designs (eight studies), recruiter differences (eight studies), incentives (two studies), and provision of trial information (19 studies). Strategies that increased people's awareness of the health problem being studied (e.g., an interactive computer program [relative risk (RR) 1.48, 95% confidence interval (CI) 1.00-2.18], attendance at an education session [RR 1.14, 95% CI 1.01-1.28], addition of a health questionnaire [RR 1.37, 95% CI 1.14-1.66]), or a video about the health condition (RR 1.75, 95% CI 1.11-2.74), and also monetary incentives (RR1.39, 95% CI 1.13-1.64 to RR 1.53, 95% CI 1.28-1.84) improved recruitment. Increasing patients' understanding of the trial process, recruiter differences, and various methods of randomisation and consent design did not show a difference in recruitment. Consent rates were also higher for nonblinded trial design, but differential loss to follow up between groups may jeopardise the study findings. The study's main limitation was the necessity of modifying the search strategy with subsequent search updates because of changes in MEDLINE definitions. The abstracts of previous versions of this systematic review were published in 2002 and 2007.ConclusionRecruitment strategies that focus on increasing potential participants' awareness of the health problem being studied, its potential impact on their health, and their engagement in the learning process appeared to increase recruitment to clinical studies. Further trials of recruitment strategies that target engaging participants to increase their awareness of the health problems being studied and the potential impact on their health may confirm this hypothesis.
