📊 Key findings:
Clinical recommendations alone are insufficient to reduce low-value care in the case of Vit D tests. Insurance coverage restrictions proved more effective than guidelines, reducing unnecessary vitamin D testing by 62% and saving 15.65 million CHF annually. However, coverage restrictions increase administrative burden and risk underuse.
