Can a patient with stable condition be discharged home with furosemide (loop diuretic) and continue the prescription from their primary care physician (PCP)?

Furosemide Discharge and Continuation with PCP for Stable Patients

Yes, a stable patient can be safely discharged home with furosemide and continue the prescription through their primary care physician, provided appropriate monitoring is established and the patient is educated about potential side effects. 1, 2

Criteria for Safe Discharge with Furosemide

• Patients should be clinically stable with adequate peripheral perfusion and controlled blood pressure before discharge with furosemide 1
• Regular monitoring of renal function and electrolytes should be arranged through the PCP, with initial follow-up within 1-2 weeks after discharge 1
• Patients should be educated about monitoring for signs of fluid and electrolyte imbalance (thirst, weakness, muscle cramps, hypotension, tachycardia) 2
• Stable patients can be maintained on oral furosemide at appropriate doses with continued PCP monitoring 1

Monitoring Requirements After Discharge

• For stable heart failure patients, ESC guidelines recommend renal function monitoring at baseline, then 1-2 weeks after initiation or dose change 1
• Serum electrolytes (particularly potassium), creatinine, and BUN should be checked frequently during the first few months of therapy and periodically thereafter 2
• Once stable, regular monitoring can occur at 4-month intervals according to ESC guidelines 1
• The ACCF/AHA guidelines suggest a pragmatic approach to furosemide dosing based on daily weight monitoring, with adjustments made in primary care as necessary 1

Potential Risks and Precautions

• Excessive diuresis can cause dehydration and blood volume reduction with risk of circulatory collapse, particularly in elderly patients 2
• Electrolyte depletion (especially hypokalemia) may occur during furosemide therapy, particularly with higher doses and restricted salt intake 2
• Furosemide should be discontinued if there is significant worsening of renal function or dehydration 1
• High doses of furosemide (>80 mg daily) have been associated with poorer outcomes in stable heart failure patients and should be avoided if possible 3

Optimizing Outpatient Furosemide Management

• For stable heart failure patients, the lowest effective dose should be used - studies show that some patients can be maintained on as little as 20 mg daily 4
• In stable patients with heart failure, furosemide can be given orally at doses of 2-5 mg/kg per day, with appropriate monitoring 1
• Periodic reevaluation of clinical status and diuretic requirements is critical for optimal management of patients with heart failure 4
• Consider diuretic deprescribing in stable patients without signs of congestion, as successful withdrawal has been demonstrated in appropriate candidates 1

Discharge Planning and PCP Coordination

• Clear communication of the discharge medication regimen to both the patient and PCP is essential to avoid confusion and reduce likelihood of readmission 1
• The PCP should be informed of any medication changes made during hospitalization and the rationale behind current dosing 1
• Patients should be instructed to monitor daily weights and report significant changes to their PCP 1
• Follow-up appointments should be scheduled before discharge to ensure continuity of care 1

By following these guidelines, stable patients can be safely discharged home with furosemide therapy that can be continued under PCP supervision, reducing hospitalization time while maintaining appropriate management of their condition.
