Insight Is Insufficient

In this depressing trial, we witness a disheartening truth – physicians won’t necessarily do better, even if they know they’re not doing well.

This study tested a mixed educational and peer comparison intervention on primary care physicians in Switzerland, with an end goal of improving antibiotic stewardship for common ambulatory complaints. The “worst-performing” 2,900 physicians with respect to antibiotic prescribing rates were enrolled and randomized to the study intervention or none. The study intervention consisted of materials regarding appropriate prescribing, along with personalized feedback regarding where their prescribing rate ranked compared to the entire national cohort. The core of their hypothesis involved whether just this passive knowledge regarding their peer performance would exert normalizing influence over their practice.

Unfortunately, despite providing these physicians with this insight, as well as tools for improvement, the net effect of their intervention was effectively zero. There were some observations regarding changes in prescribing rates for certain age groups, and for certain types of antibiotics, but dredging through these secondary outcomes leads to only unreliable conclusions.

This is not particularly surprising data. These sorts of passive feedback mechanisms unhitched from material consequences have never previously been shown to be effective. There are other, more effective mechanisms – focused education, decision-support interventions, and shared decision-making – but, for a fragmented, national health system, this represented a relatively inexpensive model to test.
