RESUMO
Travel constraints can hinder the recruitment of eligible research participants in clinical trials, causing research timeline extensions, added costs, underpowered results, and early termination. Remote consenting can help solve these issues by allowing researchers and potential participants to connect remotely. This controlled experimental study investigates the effect of remote consenting on workload, workflow, usability, and barriers and facilitators to its implementation. Using a mixed experimental design, simulated consenting sessions were conducted with three different modalities (remote paper consent, eConsent, and teleconsent) with 23 researchers and 93 research participants. Each session involved a single researcher who experienced all three modalities, while three different research participants were assigned to each modality individually. Research participants and researchers completed surveys measuring workload and usability. Remote consenting allows researchers and participants to connect at their preferred location and time, and teleconsenting was found to be the preferred modality by the researchers, primarily due to its ability to exchange visual cues. However, challenges such as training requirements and technology dependence need to be addressed for widespread implementation. Future research should aim to eliminate these barriers and improve remote consenting modalities to facilitate clinical research participation.
