3.1. Overall response rate
Six hundred and twenty one of 1212 EIN members (51%)
submitted responses to the survey. The response rates were
significantly higher among members with 15 or more years of
practice experience since completion of their ID fellowship than
for respondents with less experience (60% vs. 43%, respectively;
p < .0001). The response rates were not different for U.S. Census
Bureau division of practice location or for employment type.
Sixty-four of these respondents (10%) reported that they had not
treated CDI in the prior 6 months and were omitted from further
data analysis. The total numbers of responses to individual
questions varied because not all respondents answered all the
questions.
