Is maintenance digoxin necessary in geriatric patients?

Area of Science:

• Geriatric Medicine
• Cardiology
• Pharmacology

Background:

• Digoxin is a cardiac glycoside used to treat heart failure and arrhythmias.
• Appropriate indications and contraindications for digoxin therapy in the elderly are crucial for safe and effective treatment.

Purpose of the Study:

• To assess the necessity of continuing digoxin therapy in geriatric patients.
• To determine the proportion of elderly patients who could safely discontinue digoxin.

Main Methods:

• A four-year prospective study involving digoxin withdrawal in geriatric wards.
• Established clear criteria for digoxin withdrawal and contraindications.
• Patients were reassessed two months post-withdrawal for signs of cardiac failure or arrhythmias.

Main Results:

• Digoxin was withdrawn from 141 patients.
• Of 134 patients assessed after two months, 108 (81%) did not require continued digoxin treatment.
• This suggests a high rate of unnecessary digoxin use in this population.

Conclusions:

• A substantial proportion of elderly patients may be receiving digoxin without clear indications.
• Systematic review and potential withdrawal of digoxin in geriatric patients can be beneficial.
• This study highlights the importance of regular medication review in elderly care.
