When doctors try to manage medications for older patients in hospitals, they often look for ways to simplify treatment. One common practice is "deprescribing," which means stopping a medication that might no longer be necessary. However, new data suggests that stopping certain acid-reducing drugs, known as proton pump inhibitors (PPIs), might have unexpected consequences.
Researchers looked at nearly 5,000 hospitalized older adults who were taking five or more medications. They compared patients who had their PPIs stopped to those who started using them. The results showed that patients whose medication was stopped had a much higher likelihood of developing a serious stomach infection called Clostridioides difficile (CDI). In contrast, patients who started new doses did not show an increased risk.
It is important to note that this finding comes from a secondary analysis, meaning it is one way of looking at existing data. The researchers also warned that the results might be influenced by "confounding by indication." This means the reason a doctor chose to stop a drug in the first place might have been related to the patient's health status or risk factors, which could cloud the direct link between the medication and the infection.
