Poll Results: Low-Dose Aspirin Use in Older Adults

Mrs. L is an 81-year-old female who reports for her annual cardiology visit. Her medical history can be found here.

The below poll questions were posed in response to Mrs. L's primary request to discuss a reduction in the number of medications she is presently prescribed.

Poll Results: Low-Dose Aspirin Use in Older Adults

Most respondents agreed that aspirin (79.44%) should be deprescribed. The patient is taking aspirin for primary prevention despite having no prior history of a coronary event. In the ASPREE trial, 19,114 older adults with median age of 74 years were randomized to aspirin (n = 9,525) and placebo (n = 9,589). The findings from this trial demonstrated that the use of low-dose aspirin as a primary prevention strategy in older adults resulted in a significantly higher risk of major hemorrhage and an equivalent risk of cardiovascular events when compared to placebo.1 Moreover, the risk of hemorrhage in this patient is increased with concurrent anticoagulant use for atrial fibrillation.

Pantoprazole may be deprescribed (since it is on the Beers Criteria2) as a potentially inappropriate medication (PIM). However, in this patient it is reasonable to continue it due to her gastroesophageal reflux disease (GERD) diagnosis and to decrease probability of gastrointestinal bleed. One consideration could be to switch to a H2 antagonist (such as ranitidine, etc.) from the proton pump inhibitor (pantoprazole) after discussion with gastroenterology.

Warfarin should not be deprescribed because of continued atrial fibrillation and risk of stroke with evidence showing greater benefit of using anti-coagulants long term compared to anti-platelets.3

Poll Results: Low-Dose Aspirin Use in Older Adults

All of the above (time, trust, and risk of serious events) as stated by respondents have been shown to be barriers to deprescribing.5-7 Deprescribing is the act of removing medications or decreasing doses, under healthcare supervision and for a specific outcome. Deprescribing requires three items: a trigger, a framework (that considers a comprehensive clinical status – which includes geriatric specific conditions), and a process (Figure 1).4
