PI-REAL: A study of informed consent (IC) communication in real-time during phase I clinical trial encounters.

Abstract

22 Background: Advanced cancer patients (ACP) in phase I clinical trials are unable to recall significant elements of IC, yet the actual verbal and non-verbal content of trial discussion between oncology fellows and ACP consenting in real time to such trials has not been well described. Methods: Phase I Communication in Real Time Fellow-ACP Encounters (PI-REAL) study is an evidence-based intervention designed to improve communication about phase I clinical trial IC. ACP completed follow-up questionnaires after new patient visits to assess understanding of IC elements, such as research purpose. Video recordings were analyzed using CanCode for verbal and non-verbal skills associated with IC elements. Results: To date, 61 ACP-fellow clinical encounter video recordings were available for analysis. Average length of encounters: 45.4 min (range: 5.7-87.8 min). ACP demographics included: median age 60y (33-83); 55% male; 89% Caucasian; 55% median income > $60,000. Fellows were coded as verbally disclosing: 1. Purpose of phase I trial as dose-determining in 49% of encounters; 2. Physical risks of trial in 75% of encounters; 3. Potential benefits (e.g. improved QOL) gained by ACP participation in trial in 70% of encounters; 4. Alternatives to trial entry (e.g. other trials, palliative/supportive care) in 55% of encounters. A significant association existedbetween coded fellow empathic statements and ACP subsequently recalling the purpose of the trial as dose-determining, with 72% of subjects who heard empathic statements identifying “dosage” compared to 10% of subjects who did not (72% v. 10%, p < 0.05). Regarding non-verbal skills, fellows: leaned toward ACP in 64% of encounters; observed ACP face directly in 72% of encounters; had relaxed body posture in 55% of encounters; and displayed responsive facial expressions in 77% of encounters. Conclusions: Empathic statements by fellows appear to be associated with improved ACP understanding of Phase I trial research purpose as dose-determining. Additional encounters continue to undergo video recording and analysis.
