Informed Consent in Two Alzheimer's Disease Research Centers: Insights From Research Coordinators

Consent Builder: an innovative tool for creating research informed consent documents

Objective

To describe process innovations related to research informed consent documents, and development and formative evaluation of Consent Builder, a platform for generating consent documents for multicenter studies.

Materials and Methods

Analysis of Institutional Review Board workflows and documents, followed by process redesign, document redesign, and software development. Locally developed software leverages REDCap and LaTeX. A small-scale usability study was conducted.

Results

Process innovations were combining document types, and conceptualizing 2-part informed consent documents: part 1 standardizing the study description and part 2 with local site verbiage. Consent Builder was implemented in the Trial Innovation Network. User survey scores were acceptable; but areas for improvement were noted. LaTeX coding was the biggest challenge for users.

Discussion

The process changes were generally well accepted. The software implementation uncovered un-accounted for assumptions, and variability in IRB review workflow across centers. Technical modifications may be needed before widespread implementation.

Conclusion

We demonstrated proof-of-concept of an approach to generate research consent documents that are consistent across sites in study description, but which allow for customization of local site verbiage. The Consent Builder tool is an example of an operational innovation, helping meet a need that arose in part due to regulations around use of Single IRB for multicenter trials.

Participation in and withdrawal from cancer clinical trials: A survey of clinical research coordinators

Objective

Poor accrual and withdrawal are the main reasons for the failure of cancer clinical trials. As clinical research coordinators (CRCs) work at the frontlines of clinical trials, CRCs can best identify the main factors that influence patient participation and dropout and suggest potential remedial measures. This study aimed to investigate participation and withdrawal in cancer clinical trials through a survey of CRCs. Furthermore, we collected suggestions of CRCs to increase patient participation and reduce withdrawal from cancer clinical trials.

Methods

This cross-sectional survey among 100 CRC nurses currently coordinating cancer clinical trials and having more than six months of experience was conducted at four hospitals in South Korea between March and August 2021. We designed a questionnaire based on prior studies, and the key items included characteristics of respondents, characteristics of clinical trials, clinical trial participation, and withdrawal.

Results

Patients refused to participate due to concern about adverse events (46.5%) and negative perception of clinical trials (44.4%). The main reasons for study withdrawal were disease progression (71.5%), adverse events (10.6%), and withdrawal of consent due to personal issues (5.5%). The provision of sufficient explanation was suggested as a remedial measure for increasing consent to participate (67.4%) and reducing withdrawal (21.8%).

Conclusions

A survey of CRCs revealed the reasons governing patient participation and withdrawal in cancer clinical trials, thereby providing a novel insight into strategies for promoting subject enrollment and reducing withdrawal from cancer clinical trials.
