Post-Discharge Heart Failure With Conflicting Diuretic Orders
A 74-year-old woman is seen in your clinic the day after discharge for a heart failure exacerbation. She lives alone. Her daughter is out of state. The discharge summary lists furosemide 40 mg twice daily (an increase from her prior dose), metoprolol succinate 25 mg daily, spironolactone 12.5 mg daily, and potassium chloride 20 mEq daily. Her home bottle of furosemide is labeled 20 mg daily, and she has been taking that, plus the potassium, because 'it was already in the cabinet.' She has no scale at home. She reports 2-pillow orthopnea and her shoes feel tight. Weight today is 1.5 kg above the discharge weight. She has no transportation and her primary care follow-up is scheduled in 3 weeks.
1. What are your priorities in this visit, in order? Justify what you are not doing today.

Order of priorities
- Assess volume status and safety right now - orthopnea, edema, lung sounds, weight trend, BP, HR, and a basic metabolic panel if you can obtain it today (she is on furosemide plus spironolactone plus potassium, so hyperkalemia and worsening renal function are live risks).
- Do not let her leave without a corrected medication list. She is under-dosing the diuretic and taking a supplement whose need depends on the diuretic dose and renal function.
- Same-day or next-day contact with the discharging or covering prescriber to confirm the intended regimen. The discharge summary is the best available record, but you do not independently start 40 mg BID on a 74-year-old with unknown renal function on the basis of a faxed document.
- Close the follow-up gap - a 3-week PCP visit is too far for a patient 24 hours post-HF discharge with recurrent congestion.
What I am deliberately not doing today: giving a broad 'heart failure teaching' session. She is symptomatic and confused about her pills; education will not stick until the regimen is correct and the follow-up safety net exists.
2. Describe how you reconcile the medications and what you say and do about the potassium.

Reconciliation approach
- Use a single source of truth hierarchy: discharging prescriber confirmation > discharge summary > pharmacy fill history > patient's cabinet. When they conflict, the tiebreaker is the prescriber, not the loudest document.
- Bring in the actual bottles, not a verbal list. Call the retail pharmacy for the fill history - it will show what she is actually taking and when.
- Ask specifically about over-the-counter products, supplements, and any remaining predischarge bottles she kept.
The potassium specifically
- Do not simply tell her to keep taking it or to stop it. Potassium 20 mEq daily alongside furosemide, spironolactone, and an ACE inhibitor/ARB or MRA is a hyperkalemia setup, but stopping it in a patient who may be under-diuresed is also a judgment call that belongs to the prescriber.
- Get a potassium and creatinine today if at all possible, then relay the values when you reach the prescriber and get an explicit instruction.
- In the interim, tell her plainly: 'Keep taking your heart pills exactly as the bottle says until we call you back today with the corrected list. Do not take extra water pills.' Give her a written, dated list with the old bottles physically removed from the cabinet.
3. She cannot drive and has no scale. What care-coordination actions do you initiate before she leaves, and how do you follow up?

Barriers and matched interventions
- No scale: have the clinic provide one today or arrange pharmacy/home-health delivery; teach daily weights with the same scale, same time, same clothing.
- No transportation: arrange a telehealth or phone check within 48–72 hours, a home health nursing referral for weights and assessment, or ride services through her insurer or community programs. Do not schedule a follow-up she cannot attend.
- Lives alone, daughter out of state: ask permission to include the daughter by phone for the medication teach-back, and confirm an emergency contact.
- 3-week PCP gap: request a sooner slot or a bridge visit with a heart failure clinic or home health; the transitional-care window is the highest-risk period.
Follow-up plan
- Phone check in 48 hours: weight, orthopnea, pill list read back, red-flag review.
- Explicit call parameters: weight gain >2 lb in a day or >5 lb in a week, increasing shortness of breath, inability to lie flat, dizziness, or decreased urination.
- Document who was contacted, when, and what the prescriber ordered - the coordination trail is the deliverable.
