Figure 3. Health care providers’ confidence in their knowledge about genetic testing in cardiology.

Participants’ responses to 13 “I feel confident in …” statements. Respondents were asked to assess how confident they felt with each task on a Likert scale, from “strongly disagree” to “strongly agree.” Percentages along the left axis represent the percentages of participants who are not confident in the task (participants who “strongly disagreed” or “disagreed”). Percentages centered in the gray boxes represent percentages of participants who neither agree nor disagree to have confidence in the task. Percentages along the right axis represent the percentages of participants who feel confident with the task (participants who “strongly agreed” or “agreed”). With the exception of confidence to “identify the best person to initiate genetic testing,” confidence scores for all questions differed statistically significantly (P<0.005) between genetics and nongenetics professionals. VUS indicates variant of uncertain significance.
