- The objective of this study was to compare, using hypothetical research scenarios, different models of patient notification and authorization used in comparative effectiveness research. Respondents were asked about their willingness to participate, acceptability of the notification and authorization approach, their understanding of the research, perception of personal risks or benefits, and trust.
- The approaches to notification and authorization included:
- Written consent
- Oral consent with and without an information sheet
- General notification with opt-out
- Post-notification after the study is done
- One finding of the study is that people have difficulty understanding aspects of pragmatic trials of commonly used medical practices. There are misconceptions about both research and clinical care.
To gain more evidence about the effectiveness of alternative approaches, we need to design and conduct nested comparisons within pragmatic trials. Depending on the nature of the trial, one could compare oral versus written consent or general notification versus oral consent—and then evaluate the outcomes.
With respect to understanding and willingness to participate, what influence does the relationship between participant and clinician play? In other words, how important is the role of providers?
Different people want different amounts of information. What are the barriers to reducing the size of consent documents?
