Guideline implementation is effective at reducing proton pump inhibitor use in hematology-oncology units: A multidisciplinary intervention for reducing Clostridioides difficile risk

We implemented a guideline for appropriate acid suppressant use in hematology-oncology patients. This intervention resulted in a sustained reduction in proton pump inhibitor (PPI) use without an increase in rates of gastrointestinal bleeding. Practice guidelines are effective in reducing PPI use, which is associated with risk of Clostridioides difficile...
