The Use of Technology in Participant Tracking and Study Retention: Lessons Learned From a Clinical Trials Network Study.

ABSTRACT: BACKGROUND:The growing use of newer communication and Internet technologies, even among low-income and transient populations, require research staff to update their outreach strategies to ensure high follow-up and participant retention rates. This paper presents the views of research assistants on the use of cell phones and the Internet to track participants in a multisite randomized trial of substance use disorder treatment. METHODS:Preinterview questionnaires exploring tracking and other study-related activities were collected from 21 research staff across the 10 participating US sites. Data were then used to construct a semistructured interview guide that, in turn, was used to interview 12 of the same staff members. The questionnaires and interview data were entered in Atlas.ti and analyzed for emergent themes related to the use of technology for participant-tracking purposes. RESULTS:Study staff reported that most participants had cell phones, despite having unstable physical addresses and landlines. The incoming call feature of most cell phones was useful for participants and research staff alike, and texting proved to have additional benefits. However, reliance on participants' cell phones also proved problematic. Even homeless participants were found to have access to the Internet through public libraries and could respond to study staff e-mails. Some study sites opened generic social media accounts, through which study staff sent private messages to participants. However, the institutional review board (IRB) approval process for tracking participants using social media at some sites was prohibitively lengthy. Internet searches through Google, national paid databases, obituaries, and judiciary Web sites were also helpful tools. CONCLUSIONS:Research staff perceive that cell phones, Internet searches, and social networking sites were effective tools to achieve high follow-up rates in drug abuse research. Studies should incorporate cell phone, texting, and social network Web site information on locator forms; obtain IRB approval for contacting participants using social networking Web sites; and include Web searches, texting, and the use of social media in staff training as standard operating procedures.

Project description:BackgroundDespite having many advantages, online eHealth trials are not without challenges-notably, participant recruitment, and outcome data retention. Moreover, publications from these trials rarely provide detailed information on the methods used for recruitment and retention or discuss implications of the methods for future studies.ObjectiveTo address this need for empirical guidance regarding recruitment and outcome data retention planning, we aim to describe the methods and lessons learned from the recruitment and retention procedures used in a large randomized trial of 2 Web-based smoking cessation interventions.MethodsTo ensure a demographically and geographically diverse participant sample, we used the recruitment strategies (1) traditional, (2) Web-based, and (3) online survey panel methods and adaptively modified each in response to recruitment success. At baseline, participants indicated how they heard about the study and answered demographic questions. To maximize trial retention at each of the 3-, 6-, and 12-month assessment points, 4 survey modalities (first Web, followed by phone, mail, and postcard) were sequentially timed over a 30-day period. Participants received US $25 for submitting their responses, regardless of modality, and received an additional US $10 bonus for completing the Web survey within 24h of electronic notification.ResultsWe randomized 2637 smokers in 16 months and achieved 88% retention at 12-months. Participants (79.26% female, 72.60% Caucasian) were recruited from all 50 states. The majority of participants were recruited through Facebook (49.43%), followed by the survey panel (20.85%), free internet sources (14.54%), traditional media (11.34%), and Google ads (3.84%). Descriptively, participant demographics varied by recruitment source. Of the completed follow-up surveys, most were completed by Web (92%). Retention rates did not vary by recruitment source.ConclusionsContinuous monitoring and refinement of multiple recruitment methods, particularly of online advertising campaigns, allowed us to maximize the effectiveness of recruitment strategies in recruiting a large, diverse sample of smokers. Likewise, offering multiple follow-up survey modalities in sequential order along with time-dependent bonus incentives enabled us to obtain outcome data from a very high level of enrolled participants for the duration of the trial protocol. These strategies may be similarly useful in other trials.Trial registrationClinicalTrials.gov NCT01812278; https://clinicaltrials.gov/ct2/show/NCT01812278 (Archived by WebCite at http://www.webcitation.org/71gy5GLvO).

Project description:Introduction: Peri-operative window trials, using molecular biomarkers as surrogate endpoints for treatment response, offer investigators a uniqueopportunity to obtain intact tumor samples at 2 different time-points and thus evaluate potential biomarkers over a short period of time. Here we report results of a pilot trial designed to determine if treatment-mediated changes in gene expression can be detected after a 10-day exposure to anastrozole in estrogen receptor (ER)-positive breast cancer compared to untreated controls. Methods: Paired tumor samples (biopsy and surgical) were obtained from 26 postmenopausal women with ER-positive breast cancer. Patients were assigned anastrozole (1mg/dy) for 10 days immediately prior to surgery (13 cases) or no treatment (13 controls). 502 cancer-related genes were examined by the DASL FFPE-based cDNA array (moderated t-test, p ≤ .005). Surrogate biomarkers reflecting changes in gene expression were examined by immunohistochemistry (IHC) (Wilcoxon rank-based test, p < .05). Results: Sufficient RNA was available from 19 paired samples (8 controls, 11 cases). There was no difference in age, tumor size, grade, or baseline biomarker expression between groups. Within each group, 18 genes, reflecting roles in proliferation, angiogenesis, and apoptosis showed differential expression over time from biopsy to surgery (p < 0.005). Dysregulation of estrogen-related genes was present only in the treated group. Comparison between groups identified 5 genes that were significantly dysregulated between controls and treated cases (BAG1/ING1/ERBB4/IFNGR1/TFDP1). Reduction in Ki-67 index was observed in 7 (54%) treated cases in 1 (7.7%) control patient. Conclusions: Short-term (10-day) exposure to anastrozole resulted in significant dysregulation of 18 out of 502 cancer-related genes, and Ki-67 was reduced in 54% of cases. However, the local effects of wound healing may represent a confounding factor in the interpretation of peri-operative window trials as exposed by the changes in gene expression and the increased Ki-67 index in the control group. Prospective, paired tumor samples (biopsy and surgical) were obtained from 26 postmenopausal women with ER-positive breast cancer. Patients were assigned anastrozole (1mg/dy) for 10 days immediately prior to surgery (13 cases) or no treatment (13 controls). 502 cancer-related genes were examined by the DASL FFPE-based cDNA array. Sufficient RNA for gene expression analysis was obtained from 19/26 (73%) FFPE paired (biopsy and surgery) samples (8 controls, 11 anastrozole-treated patients

Project description:BackgroundAlthough the majority of American Indians/Alaska Natives reside in urban areas, there are very few randomized controlled trials analyzing culturally centered substance use prevention interventions for this population.MethodsWe describe methods employed to recruit and retain urban American Indian/Alaska Native adolescents into a randomized controlled trial, which was focused on testing the potential benefits of a substance use prevention intervention for this population. We also report challenges encountered in recruitment and retention of participants and strategies employed addressing these challenges. Data collection occurred from August 2014 to October 2017.ResultsWe partnered with two community-based organizations in different cities in California. We utilized American Indian/Alaska Native recruiters from communities, placed flyers in community-based organizations, and asked organizations to post flyers on their web and social media sites. We also offered gift cards for participants. Our initial recruitment and retention model was moderately successful; however, we encountered five main challenges: (1) transportation, (2) increasing trust and interest, (3) adding research sites, (4) getting the word out about the project, and (5) getting youth to complete follow-up surveys. Strategies employed to overcome transportation challenges included shortening the number of sessions, offering sessions on both weekends and weekdays, and increasing bus tokens and transportation options. We hired more staff from American Indian/Alaska Native communities, added more research sites from our previously established relationships, and were more proactive in getting the word out on the project in American Indian/Alaska Native communities. We also utilized more field tracking and emailed and mailed survey invitations to reach more participants for their follow-up surveys. Because of our efforts, we were nearly able to reach our initial recruitment and retention goals.ConclusionAlthough our research team had previously established relationships with various urban American Indian/Alaska Native communities, we encountered various recruitment and retention challenges in our study. However, by identifying challenges and employing culturally appropriate strategies, we were able to collect valuable data on the potential effectiveness of a substance use prevention intervention for urban American Indian/Alaska Native adolescents. Findings from this study assist toward the development of potentially successful strategies to successfully recruit and retain urban American Indian/Alaska Native adolescents in randomized controlled trials.
