Genetic test ordering frequency and its relationship with genetics education among US nephrologists. (A) The genetic test ordering frequency was calculated among “users” (n = 107) based on the reported number of tests ordered per month and number of unique patients seen per month for each respondent. The proportion of nephrologists who ordered genetic tests for <1% of their patients was 48.6%. (B) The reported number of tests ordered per month were stratified by the level of education in genetics indicated by each respondent (n = 149). A positive relationship was identified between physician education in genetics and the number of genetic tests ordered per month. Nephrologists with prior education in genetics ordered more genetic tests than those with no such education. Similarly, those with extensive education in genetics ordered genetic tests more frequently than those with only limited education. ∗P < 0.05. ∗∗∗∗P < 0.0001 by Kruskal-Wallis test.
