Medication-related factors associated with proton pump inhibitor prescription beyond official guidelines in older adults.

Abstract

To investigate the relationship between medications with a known risk of gastrointestinal bleeding and proton pump inhibitor (PPI) prescription not according to guidelines. An analysis of the records of 592 hospitalised patients aged 65years or older was undertaken. The number of all medicines, potentially inappropriate medicines according to the EU(7)-PIM list and the Beers Criteria 2019 and medicines with a known risk of gastrointestinal bleeding, was compared in patients with PPI prescription not given based on guidelines and in patients with no PPI prescription. Patients prescribed PPI not based on guidelines used more medications on average (9.6 vs. 6.4, p < 0.001), more PIMs according to the EU(7)-PIM list (2.4 vs. 1.1, p < 0.001) and the Beers criteria (2.0 vs. 0.6, p < 0.001) at hospital admission and at discharge (8.9 vs. 7.5, p < 0.001, mean number of medications), (2.0 vs. 1.2, p < 0.001, EU(7)-PIM list), (1.9 vs. 0.8, p < 0.001, Beers criteria) than patients with no PPI prescription. Patients prescribed PPI not according to guidelines were more frequently using direct oral anticoagulants (28% vs. 12.8%, p < 0.001), corticosteroids (5.3% vs. 0.7%, p = 0.025) at hospital admission and at discharge (25.9% vs. 16.5%, p = 0.018, oral anticoagulants), (6.6% vs. 1%, p = 0.006, corticosteroids), (13.3% vs. 5.4%, p = 0.004, warfarin) than patients with no PPI prescription. The number of medications, potentially inappropriate medications according to the EU(7)-PIM list and Beers criteria, and the use of direct oral anticoagulants, warfarin and corticosteroid prescriptions were the medication-related factors associated with PPI prescription not according to guidelines in elderly patients.
