The impact of medical recommendations is inherently difficult to measure, as there are no databases in Switzerland that measure changes in prescribing practices. A preliminary study from 2016 by the Policlinique Lausanne with the support of the SGAIM shows that almost 60% of the doctors surveyed are aware of the smarter medicine campaign; in the German-speaking part of Switzerland, the level of awareness is as high as 70%. Agreement with the recommendations of the SGAIM lists was 8.5 and 9 out of 10. The proportion of doctors who, according to their own statements, rarely deviated from the 4 recommendations in practice (not prescribing antibiotics for upper respiratory tract infections, refraining from systematic preoperative chest X-rays, avoiding diagnostic imaging of the lumbar spine in patients with acute lumbalgia without alarm signs or refraining from measuring prostate-specific antigen) was between 67 and 74%. In contrast, the recommendation for proton pump blockers (long-term pharmacotherapy for gastrointestinal symptoms without reduction to the lowest dose) is only followed by 33% of the doctors surveyed.
