Here are a few important points to keep in mind when evaluating elderly patients in the ED or when prescribing a new drug:

  • Adverse drug effects lead to 11% of ED visits in patients > 65
  • Older patients in the ED generally take > 4 medications per day, with 13% taking > 8 medications
  • 11% of elderly patients in the ED receive at least 1 inappropriate medication
  • 3 medication classes account for 48% of all ED visits for adverse drug effects in the elderly: oral anticoagulants or antiplatelet meds, antidiabetic medications, and agents with a narrow therapeutic index (e.g. digoxin, phenytoin)

Pay special attention to medication lists and new prescriptions in the elderly....much more attention than with younger patients!
