Background: Evidence-based prescribing (EBP) results in decreased morbidity and reduces medical costs. However, pharmaceutical marketing influences medication requests and prescribing habits, which can detract from EBP. Media literacy, which teaches critical thinking, is a promising approach for buffering marketing influences and encouraging EBP. The authors developed the "SMARxT" media literacy education program around marketing influences on EBP decision-making. The program consisted of six videos and knowledge assessments that were delivered as an online educational intervention through the Qualtrics platform.
Methods: In 2017, we assessed program feasibility, acceptability, and efficacy of enhancing knowledge among resident physicians at the University of Pittsburgh. Resident physicians (n=73) responded to pre-test items assessing prior knowledge, viewed six SMARxT videos, and responded to post-test items. A 6-month follow-up test was completed to quantitatively assess sustained changes in knowledge and to qualitatively assess summative feedback about the program (n=54). Test scores were assessed from pre- to post-test and from pre-test to follow-up using paired-sample t-tests. Qualitative results were synthesized through content analysis.
Results: Proportion of correct knowledge responses increased from pre-test to immediate post-test (31% to 64%, P<0.001) at baseline. Correct responses also increased from pre-test to 6-month follow-up (31% to 43%, P<0.001). Feasibility was demonstrated by 95% of enrolled participants completing all baseline procedures and 70% completing 6-month follow-up. Quantitative measures of acceptability yielded positive scores and qualitative responses indicated participants' increased confidence in understanding and countering marketing influences due to the intervention. However, participants stated they would prefer shorter videos, feedback about test scores, and additional resources to reinforce learning objectives.
Conclusion: The SMARxT media literacy program was efficacious and acceptable to resident physicians. Participant suggestions could be incorporated into a subsequent version of SMARxT and inform similar clinical education programs. Future research should assess program impact on real-world prescribing practices.
