As older adults take more medications, there is a higher risk of them being exposed to drug\u2013drug or drug\u2010disease interactions. The American Geriatrics Society in 2019 updated their Beers Criteria for Potentially Inappropriate Medication (PIM) Use in Older Adults. The objective of this study was to assess the prevalence of utilization of medications included in the 2019 Beers Criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>An analysis was conducted using the Medicare Part D Provider Utilization and Payment Data Public Use File for calendar\u2010year 2020.

The most utilized medication classes in this category were benzodiazepines (25,949,994 prescriptions), \u201cZ\u2010drugs\u201d (6,204,909 prescriptions), long\u2010acting sulfonylureas (5,306,577 prescriptions), 1st\u2010generation antihistamines (5,049,289 prescriptions), and tricyclic antidepressants (4,190,062 prescriptions). Additionally, 135\u2009million prescriptions were dispensed to Medicare beneficiaries 65\u2009years and older for medications which the Beers Criteria states to use caution (11.3% of all prescriptions) exceeding $2.85\u2009billion in medication costs. The most utilized medications for this category were diuretics (74,599,126 prescriptions), selective serotonin reuptake inhibitors (30,033,121 prescriptions), serotonin and norepinephrine reuptake inhibitors (11,858,968 prescriptions), tramadol (11,450,878 prescriptions), and mirtazapine (5,737,304 prescriptions).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Even with the existence of the AGS Beers Criteria for PIM Use in Older Adults and its continued updated versions, 16% of medications dispensed to Medicare Part D were potentially inappropriate.
