Safe Prescribing in Older ED Patients
• Review Beers’ Criteria, tool for identifying Potentially Inappropriate Medications
• Discuss most frequent medication problems in ED discharge medications
• Review strategies for reducing use of high risk medications in the ED

ED Discharge Medications
• In VAMC EDs, 45-65% of older adults are prescribed at least one new medication at the time of ED discharge• 59% - 1 new medication• 27% - 2 new medications• 14% - 3 or more
• Most common drug classes• Anti-infectives • Cardiovascular• Central nervous system

The Medication Maze
New medications and dosage
changes
Common ED discharge drugs (e.g. NSAIDs,
opioid analgesics, antibiotics) are often risky for older patients Medication
Reconciliation Across Transitions
Differentprescribers
Multiple medications and
chronic conditions
Over thecounter drugs

Potentially Inappropriate Medications
• Risk of adverse event outweighs clinical benefit
• Identifying PIMs in older adults– Beers’ Criteria– STOPP/START Criteria– HEDIS– Medication Appropriateness Index
![Page 6: Best Practices for Safe Prescribing in Older ED Patients S. Nicole Hastings, M.D., M.H.S. 1](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d8a5503460f94a70028/html5/thumbnails/6.jpg)

Beers’ Criteria
• 2012 Update with AGS• Target audience – practicing clinician• Goal - Improve care by ↓ exposure to
PIMS– Educational tool– Quality measure– Research tool
![Page 7: Best Practices for Safe Prescribing in Older ED Patients S. Nicole Hastings, M.D., M.H.S. 1](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d8a5503460f94a70028/html5/thumbnails/7.jpg)
Beers’ Criteria
• Intended clinical use– Improve care of older adults by reducing
exposure to PIMs– Guideline to identify medications for which
risk > benefit– Not meant to supersede clinical judgment
or individual patient’s values and needs– Serve as a reminder for closer monitoring
American Geriatrics Society

Beers’ Criteria
Table 2 – AvoidDrug or Class
Rationale Recommendation
Quality of Evidence
Strength of Recommendation
First generation antihistaminesExamples:-Diphenhydramine-Hydroxyzine-Promethazine
Highly anticholinergic; clearance reduced with advanced age..greater risk of confusion, dry mouth, constipation, etc (urinary retention)
Avoid Hydroxyzine and promethazine: high; all others, moderate
Strong

Anticholinergics
• Diphenhydramine• Hydroxyzine• Meclizine• Promethazine• Prochlorperazine
(Compazine)• Oxybutynin• Scopolamine• Cyclobenzaprine
J Am Geriatr Soc 2012

Prescriber Beware…..• Drug-Drug Interactions
– Warfarin, digoxin– QTc prolongation
• Drug-Disease Interactions– NSAIDS-PUD– Anticholinergics/antihistamines and bladder
outlet obstruction– Anticholinergics/antihistamines and cognitive
impairment• Dose adjust for renal insufficiency
– Cr overestimates GFR in older adults

ED Discharge Medication Problems
• Beers’ drug – 11.6%• Drug-drug interactions – 12.6%• Drug-disease interactions – 5.7%• Problem with monitoring - 17.6% • One or more – 31.8%
![Page 13: Best Practices for Safe Prescribing in Older ED Patients S. Nicole Hastings, M.D., M.H.S. 1](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d8a5503460f94a70028/html5/thumbnails/13.jpg)
ED Discharge Medication Problems
Quality Problem Examples
Drug to avoid cyclobenzaprine, diphenhydramine, indomethacin
Drug-drug interaction lisinopril - naproxen
Drug-disease interaction
amitryptyline – benign prostatic hyperplasia
Therapeutic duplication ibuprofen - naproxen
Inadequate monitoring no potassium, creatinine check after new prescription for diuretic

Suboptimal Pharmacotherapy
Time until first adverse event (repeat ED visit, hospital admission or death) among patients with: (1) no new discharge drug, (2) new discharge drug but
no suboptimal pharmacotherapy and (3) new discharge drug with suboptimal pharmacotherapy.

Before Prescribing, Consider…
• Is a medication necessary?– Think drugs with any new geriatric
syndrome
• Do the benefits outweigh the risks?• Is it used to treat effects of another
drug?• Could it interact with a disease, other
drugs?• Does the patient know what it’s for, how
to take it, and what ADEs to look for?

Safe Prescribing in Older ED Patients
• Is a medication necessary?• Is there a safer alternative?• Does the risk outweigh the benefit?• AGS Beers Criteria as a guideline • Reduce PIM use in your ED through
education, provider feedback, CPRS tools
