  "abstract": "Introduction Patient understanding of angiography and angioplasty is often incomplete at the time of consent. Language barriers and time constraints are significant obstacles. Multi-language digital animations describing the benefits, risks and alternatives of the procedure ( www.explainmyprocedure.com/iht), introduced early in the patient pathway, have previously been shown to improve understanding. We re-examined patient understanding after animations were withdrawn from service and replaced with a digital consent form.Methods In a previous evaluation 1 40 consecutive patients were interviewed, 20 before the animations were introduced (Group 1), and 20 during routine use of the animations (Group 2). We subsequently surveyed a further 20 consecutive patients after the animations were withdrawn from service (Group 3). Each patient was asked whether they felt they completely understood the procedure, understood the benefits, the risks and the alternative options. Responses to these four questions were analysed categorically and ratios calculated comparing the Groups 2 v 1 and Groups 3 v 1 (with 95% confidence intervals), respectively.Results Table 1 shows that patients in the three groups were well matched. figure 1 shows that understanding of the procedure was greater in the animation group (Group 2) than in either of the non-animation groups (Group 1 or Group 3). For Group 2 versus Group 1, there was a statistically significant 3-fold greater understanding of the risks of the procedure (ratio 3.0 (95% CI 1.2 to 7.7), p=0.023) and a 2.5-fold increase in patients feeling completely informed before giving consent (2.5 (1.2 to 5.1), p=0.01), with similar directional effects on benefits and alternatives. These effects disappeared once the animations were withdrawn (Group 3 versus Group 1), 0.75 (0.2-2.9), p=0.677) and 1.0 respectively.Conclusion Viewing animations of angiography and angioplasty before consent was associated with a greater understanding of the procedures and associated risks – improvements that were lost when the animations were withdrawn. Substituting digital animations for a digital consent form may appear a reasonable cost-saving option but the two approaches are not alternatives. Patient education and signing a consent form are complementary parts of a valid consent process.Reference Sing P, Wald DS, Cobb V.
