Clinical decision-making can be influenced by both individual and team factors. This article describes the de Groot Critically Reflective Diagnoses Protocol (DCRDP), which can be used to evaluate how group dynamics and interactions can influence collective clinical decision-making. Transcripts of recorded decision-making meetings can be coded based on six DCRPD criteria (challenging groupthink, critical opinion-sharing, research utilization, openness to mistakes, asking and giving feedback, and experimentation), which identify teams that are interactive, reflective, higher functioning, and more equitable.
