FOAM Impact: The Influence of Open-access Medical Education on Practice Uptake

The FOAM Impact study sought to examine baseline rates of intravenous (IV) lidocaine usage for the treatment of renal colic and to compare rates of use between FOAM utilizers and nonutilizers. We sought to measure the effect of FOAM resources on clinical practice by timing the release of FOAM content with publication of the LIDOKET trial.

A cross-sectional before-and-after survey was conducted and disseminated on two social media platforms. The 13-question, anonymous survey was posted for 1 week prior following the release of the LIDOKET study. Descriptive statistics, Mann-Whitney t-test, and chi-square test statistics were used to describe survey respondent characteristics and Likert responses.

There were a total of 472 survey respondents. A total of 321 physicians (75.7% of total respondents) provided pre- and postpublication survey answers. There was no significant change in the use of analgesics before and after publication of LIDOKET and concurrent REBEL EM blog post. A total of 197 (42%) survey respondents reported using lidocaine for renal colic, of which 60 respondents (13%) reported frequent or occasional use. The mean difference in perceived efficacy of lidocaine before and after publication was -0.30 (95% confidence interval [CI] = -0.80 to 0.19, p = 0.15). Being a FOAM user was not associated with changes in mean difference in perception of lidocaine efficacy (F = 0.127, p = 0.72); however, there was a significant difference in perception of lidocaine's efficacy following LIDOKET and REBEL EM publication (F = 4.718, p = 0.03).

Using an online survey-based technique, no appreciable impact of FOAM resources was immediately apparent; however, engagement with FOAM was associated with a change in perception of IV lidocaine's efficacy. To our knowledge, this is the first study of its kind to evaluate the impact of FOAM on clinical practice. The unique method of coordinating FOAM distribution with traditional medical publication may provide future opportunities for measuring the impact of asynchronous medical education resources on medical practice.
