Abstract:
Aim: Despite broad interest in advancing personalized medicine, most evidence is currently derived from average results of clinical trials that may obscure heterogeneity of trial participants. Little is known currently about how patients view heterogeneity in trials and whether they can participate in methodological discussions about this concept. Materials & methods: In structured discussions with three focus groups involving 22 participants, we assessed how representatives of patient communities have used research to guide individual treatment decisions. Discussion themes were organized into a framework describing patient decision-making in four steps: decisions patients make in the course of care; information used to make decisions; sources for information; and quality of information. Results/conclusion: Patients prioritize information that reflects their own characteristics, preferences and values. They struggle applying clinical research to their own case.
