Deprescribing proton pump inhibitors: A study in hospitalized patients in Slovenia.

Objective: To evaluate the possibility of deprescribing proton pump inhibitors in adult inpatients hospitalized in a teaching hospital in Slovenia.
Materials and Methods: We conducted a prospective observational clinical study in 120 patients taking a proton pump inhibitor. Data were obtained from hospital medical records and patient interviews. First, treatment compliance with relevant guidelines was assessed, and then the possibility of deprescribing was considered.
Results: Treatment with a proton pump inhibitor was in accordance with guidelines in only 39% of the 120 patients. In 24% of patients, the indication for proton pump inhibitor use was invalid, and 22% and 15% of patients were taking a proton pump inhibitor at a higher dose or for a longer period than recommended, respectively. Deprescribing could be undertaken in 61% of patients, as discontinuation in 38%, and dose reduction in 23%. A deprescribing possibility was noted more frequently in patients prescribed proton pump inhibitors for peptic ulcer disease, Helicobacter pylori infection, or without a valid indication (p < 0.001), as well as in patients taking a double or higher dose of a proton pump inhibitor (p < 0.001).
Conclusion: Deprescribing of proton pump inhibitors could be undertaken in nearly 2/3 of our cohort of adult hospitalized patients. Hospitalization may serve as an opportunity to deprescribe proton pump inhibitors.
