“…The usefulness of graphical presentation of information has been explored previously in making informed consent a more informed process. Methods explored include graphs and tables [3], pictograms [4], videotapes [5], and interactive multimedia programs [6]. Altering the style and substance of consent forms has shown mixed results in improving patient comprehension [7].…”

Background:The communication of risk is a difficult task, with evidence to suggest that doctors perform poorly in the attempt to convey it. Consent forms should be designed to assist in informing patients of these risks, and encourage their comprehension. The authors present a pilot study into a novel risk visualization tool (RVT) for the informed consent process, which provides probabilistic and severity information in a single graphical form.Methods: This is a prospective, randomized study of adult volunteers. One hundred volunteers were taken through a mock consent process for a laparoscopic appendicectomy, with either the RVT or standard institutional form. Results:There was greater recall of surgical risks in the group that utilized the RVT (4.94/8.0, 61%) compared to the standard consent form (3.52/8.0, 44%) (P ≤ 0.005). Participants who were given the RVT were also more likely to recall the most common risk and the most severe risk. Participants who were given the RVT also reported greater satisfaction with the informed consent process than those patients given the standard consent form. Conclusion:The results of the study suggest that a patient's ability to comprehend the risks of a surgical procedure and satisfaction with the consenting process can be improved with the use of the RVT.

Objective: Evaluate the effect of risk communication tools on the understanding of statistical risk of complications occurring in patients undergoing a surgical or interventional procedure. Summary Background Data: Informed consent is an essential process in clinical decision-making, through which healthcare providers educate patients about the benefits, risks and alternatives of a procedure. Numerical risk information is by nature probabilistic and difficult to communicate. Aids which support statistical risk communication and studies assessing their effectiveness are needed. Methods: A systematic search was performed across Medline, Embase, PsycINFO, Scopus and Web of Science until July 2021. Studies examining risk communication tools (e.g. informative leaflets, audio-video) in adults (age>16) patients undergoing a surgical or interventional procedure were included. Both randomised control trials (RCTs) and observational studies were included. Cochrane risk-of-bias and the Newcastle-Ottawa Scale were used to assess the quality of studies. Due to heterogeneity of the studies, a narrative synthesis was performed (PROSPERO ID: CRD42022285789). Results: A total of 4348 articles were identified and following abstract and full-text screening a total of 11 articles were included. 8 studies were RCTs and 3 were cross-sectional. The total number of adult patients was 1030. The most common risk communication tool used was additional written information (n=7). Of the 8 RCTs, 5 showed statistically significant improvements in the intervention group in outcomes relating to recall of statistical risk. Quality assessment of RCTs found some concerns with all studies. Conclusions: Risk communication tools appear to improve recall of statistical risk. Additional prospective trials are warranted which can compare various aids and determine the most effective method of improving patient understanding.

“…Gastrointestinal endoscopies are among the most common procedures, and despite the importance of informed consent, patients report they often receive inadequate information about these procedures. [1][2][3][4] Data examining the content of consents for endoscopy are scant, with no reports to our knowledge from North America. We sought to determine the proportion of consents for colonoscopy that contain the necessary components of consent and to identify variables associated with complete consent.…”
