## Case 1: Heart Failure, CKD, and Diabetes with Competing Treatment Priorities

### Clinical Presentation

**Patient Demographics:** 74-year-old male

**Chief Complaint:** "My legs are swelling and I'm short of breath"

**History of Present Illness:**
Mr. Rodriguez is a 74-year-old male with a complex medical history who presents with 1 week of progressive bilateral lower extremity edema, orthopnea requiring 3 pillows to sleep, and dyspnea on exertion now limiting him to walking only 1 room before needing to rest (previously able to walk around the block). He also reports a 6-pound weight gain over 10 days despite "trying to take his water pill." He denies chest pain, fever, or cough. He notes he has been eating more salty foods recently due to poor appetite for his usual low-sodium diet.

**Past Medical History:**
- Heart failure with reduced ejection fraction (EF 30%, ischemic cardiomyopathy)

- Type 2 diabetes mellitus (A1c 8.2%)
- Atrial fibrillation on anticoagulation
- Hypertension
- Gout
- Moderate aortic stenosis
- Peripheral vascular disease
- History of falls (2 in past 6 months)

**Medications (18 medications total):**
- Carvedilol 25 mg BID
- Lisinopril 20 mg daily
- Furosemide 80 mg BID
- Spironolactone 25 mg daily
- Apixaban 5 mg BID

**Social History:**
- Retired mechanic
- Lives with wife (also elderly with mild dementia)
- Daughter visits weekly
- No longer drives
- Uses a cane for ambulation

**Physical Examination:**
- **Vital Signs:** Temperature 36.8C, HR 78 bpm (irregular), BP 142/86 mmHg, RR 20/min, SpO2 93% on room air, Weight 98 kg (baseline 92 kg)
- **General:** Elderly male in mild respiratory distress when lying flat
- **Cardiovascular:** Irregularly irregular rhythm, III/VI systolic ejection murmur at RUSB, JVP 14 cm H2O, positive hepatojugular reflux
- **Lungs:** Bibasilar crackles to mid-lung fields
- **Abdomen:** Soft, mildly distended, no tenderness
- **Extremities:** 3+ pitting edema to thighs bilaterally, cool feet with diminished dorsalis pedis pulses
- **Neurologic:** Alert and oriented, no focal deficits

### Problem Prioritization Framework

**Life-Threatening/Urgent:**
1. Acute decompensated heart failure with volume overload

**Symptom-Causing (High Priority):**
2. Dyspnea and edema affecting quality of life
3. CKD with potential worsening from diuresis

**Potentially Reversible:**
4. Hyperglycemia management
5. Medication optimization (polypharmacy)

**Chronic/Stable (Lower Priority for Acute Visit):**
6. Atrial fibrillation (rate controlled)
7. Gout (not currently flaring)
8. Aortic stenosis (moderate, monitoring)

### Inpatient Workup

**Laboratory Studies:**
- BNP 2,840 pg/mL (significantly elevated)
- Sodium 132 mEq/L
- Potassium 5.4 mEq/L
- BUN 68 mg/dL, Creatinine 3.4 mg/dL (baseline 2.8)
- eGFR 18 mL/min
- Hemoglobin 9.8 g/dL
- A1c 8.2%
- Glucose 186 mg/dL
- INR 1.1 (subtherapeutic - patient admits missing apixaban doses)
- TSH 2.4 mIU/L
- Iron studies: Ferritin 42 ng/mL, TSAT 15%

**Imaging:**
- Chest X-ray: Cardiomegaly, bilateral pleural effusions, pulmonary vascular congestion
- Echocardiogram: EF 25% (decreased from 30%), moderate MR, moderate AS (unchanged)

### Competing Treatment Priorities Analysis

| Condition | Optimal Treatment | Conflict |
|-----------|------------------|----------|
| Heart failure | Aggressive diuresis | Worsens CKD, causes AKI |
| CKD | Avoid nephrotoxins, limit diuretics | Limits HF treatment |
| Diabetes | Tight glycemic control | Hypoglycemia risk with CKD |
| Hyperkalemia | Hold spironolactone/ACE-I | These are key HF medications |
| Fall risk | Reduce sedating medications | Pain control needed |
| Anticoagulation | Continue for AFib | Bleeding risk with CKD |

### Goals of Care Discussion

**Eliciting Patient Values:**
- *"What matters most to you right now?"*
- Patient response: "I want to be able to breathe and spend time with my grandchildren. I don't want to be in the hospital all the time."

**Function-Focused Goals:**
- Able to walk to the bathroom without stopping
- Sleep lying flat
- Maintain independence at home

**Treatment Limitations Discussed:**
- Patient does not want dialysis if kidneys fail
- Would want CPR attempted but not prolonged ICU stay on ventilator
- Willing to accept some decline in kidney function for better breathing

### Treatment Plan

**Immediate Management (with attention to competing priorities):**
1. **Diuresis:** IV furosemide 80 mg BID with close creatinine monitoring
   - Accept some worsening of creatinine for symptom relief
   - Goal: net negative 1-2 L/day
2. **Potassium management:** Hold spironolactone temporarily, low-K diet
3. **Diabetes:** Stop metformin (contraindicated with eGFR < 30), continue insulin, reduce glipizide (hypoglycemia risk with CKD)
4. **Anticoagulation:** Resume apixaban (renal dose 2.5 mg BID given eGFR < 25)

**Medication Reconciliation - Deprescribing Opportunities:**
5. Stop metformin (CKD contraindication)
6. Reduce gabapentin dose (renally cleared, contributing to fall risk)
7. Stop omeprazole (no clear indication, contributes to hypomagnesemia, CKD risk)
8. Stop aspirin (on anticoagulation, no recent ACS - discuss with cardiology)
9. Consolidate calcium/vitamin D timing

**Care Coordination:**
10. Social work consult for home safety assessment
11. PT/OT evaluation for fall prevention
12. Home health referral for medication management
13. Palliative care consult for goals clarification and symptom management

- **Abdomen:** Soft, mildly distended, no bowel movement in 3 days

### Delirium Assessment

**CAM (Confusion Assessment Method):**
1. Acute onset and fluctuating course: YES
2. Inattention: YES
3. Disorganized thinking: YES
4. Altered level of consciousness: YES (fluctuates between drowsy and agitated)

**CAM Positive = DELIRIUM**

**Delirium Risk Factors in This Patient:**
- Advanced age
- Acute infection
- Sensory impairment (hearing, vision)
- Constipation
- New psychoactive medications (tramadol, lorazepam, diphenhydramine, zolpidem)
- Sleep disruption in hospital
- Unfamiliar environment

### Root Cause Analysis - Medication Review

**HIGH-RISK MEDICATIONS CONTRIBUTING TO DELIRIUM:**

| Medication | Mechanism | Action |
|------------|-----------|--------|
| Tramadol | Serotonergic + opioid | STOP - high delirium risk |
| Diphenhydramine | Anticholinergic | STOP immediately |
| Lorazepam | Benzodiazepine | STOP - paradoxical agitation |
| Zolpidem | Z-drug | STOP - confusional states |

**Beers Criteria Violations:**
- Diphenhydramine: Avoid in elderly (anticholinergic, sedating)
- Benzodiazepines: Avoid in elderly (falls, cognitive impairment)
- Zolpidem: Avoid in elderly (falls, delirium)

### Treatment Plan

**Immediate - Address Reversible Causes:**
1. **Medication deprescribing:**
   - Stop tramadol, diphenhydramine, lorazepam, zolpidem
   - Use scheduled acetaminophen for pain
2. **Constipation:** Aggressive bowel regimen (docusate, senna, consider enema)
3. **Sensory optimization:** Hearing aids in, glasses on, adequate lighting
4. **Reorientation:** Clock, calendar, familiar photos in room
5. **Sleep hygiene:** Minimize nighttime interruptions, lights off at night

**Environmental/Non-Pharmacologic:**
6. Family presence during day
7. Early mobilization with PT
8. Avoid physical restraints
9. Normalize sleep-wake cycle

**Pharmacologic (if severe agitation):**
10. Haloperidol 0.5-1 mg PO/IV PRN severe agitation (not scheduled)
11. Avoid benzodiazepines except for alcohol/benzo withdrawal

**Ongoing Management:**
12. Daily reassessment of mental status
13. Transition antibiotics to oral for discharge
14. Family education about delirium and recovery expectations
15. Outpatient cognitive screening at follow-up

### Functional Assessment for Discharge Planning

**ADLs Assessment (comparing to baseline):**
| Activity | Baseline | Current |
|----------|----------|---------|
| Bathing | Independent | Needs supervision |
| Dressing | Independent | Needs assist |
| Toileting | Independent | Needs assist |
| Transferring | Independent | Needs assist |
| Continence | Continent | Incontinent of urine |
| Feeding | Independent | Needs cueing |

**Recommendation:** Cannot discharge home independently. Options:
- Short-term rehabilitation for reconditioning
- Home with 24-hour family supervision initially
- Home with home health aides

## Case 3: End-Stage COPD with Goals of Care Complexity

### Clinical Presentation

**Patient Demographics:** 71-year-old female

**Chief Complaint:** "I can't keep doing this"

**History of Present Illness:**
Mrs. Thompson is a 71-year-old female with very severe COPD (GOLD Stage IV, FEV1 22% predicted) on 4L home oxygen who presents with her third COPD exacerbation in 6 months. She reports 5 days of worsening dyspnea, increased sputum production (yellow-green), and fatigue. She was discharged from the hospital 3 weeks ago. During this visit, she tearfully states, "I don't want to keep living like this. I can barely make it to the bathroom."

- **Lungs:** Diffuse wheezes, prolonged expiration, accessory muscle use
- **Cardiovascular:** Distant heart sounds, JVP 10 cm
- **Extremities:** 1+ edema, muscle wasting
- **Mood:** Tearful, expresses hopelessness

### Prognostic Assessment

**Markers of Poor Prognosis in COPD:**
- FEV1 < 30% predicted
- Frequent exacerbations (3 in 6 months)
- Hospitalizations increasing
- Functional decline (now bedbound)
- Malnutrition (BMI < 20)
- Chronic hypoxemia despite oxygen
- Cor pulmonale (pulmonary hypertension, edema)

**BODE Index:** Score 8-10 (indicates 50% 4-year mortality)

**Estimated Prognosis:** Months to approximately 1-2 years

### Goals of Care Conversation

**Opening:**
*"Mrs. Thompson, you mentioned you don't want to keep living like this. Can you tell me more about what you mean?"*

**Patient's Expressed Goals:**
- Does not want to suffer at the end
- Wants to stay home as much as possible
- Worries about being a burden on her husband
- Does not want to be on a breathing machine again
- Wants to see her grandson graduate high school (in 4 months)

**Goals of Care Discussion Framework:**

**Explore:**
- "What is your understanding of where you are with your illness?"
- "When you think about the future, what worries you most?"
- "What brings you the most joy or meaning right now?"

**Inform:**
- "Based on how things have been going, I'm worried that your COPD is getting harder to control. You've needed to be in the hospital three times in six months."
- "I want to be honest with you - even with all our treatments, your lungs are very fragile."

**Recommend (based on her goals):**
- "Given what you've told me about wanting to stay home and not suffer, I think we should focus our treatments on keeping you comfortable. I'd recommend we talk about hospice, which could provide extra support at home."

### Treatment Plan

**Acute Management:**
1. Treat current exacerbation (steroids, bronchodilators, antibiotics)
2. Optimize comfort medications (continue morphine, adjust PRN)
3. Palliative care consultation

**Goals-Concordant Planning:**
4. **Code Status Discussion:**
   - Explained that CPR/intubation very unlikely to be successful given severity
   - Patient elects DNR/DNI
   - Documents wishes in POLST form

5. **Hospice Referral:**
   - Meets criteria (prognosis < 6 months with supportive criteria)
   - Patient agrees to hospice enrollment
   - Will provide: home nursing, aide services, medications, equipment, 24/7 support

6. **Symptom Management Plan:**
   - Continue morphine for dyspnea (may increase as needed)
   - Lorazepam for anxiety/dyspnea
   - Continue oxygen for comfort
   - Reduce unnecessary medications

**Family Meeting:**
7. Included husband to ensure understanding of prognosis and plan
8. Social work for caregiver support resources
9. Discussed what to expect and when to call hospice vs. 911

## Discussion Questions

1. **Competing Priorities:** In Case 1, the patient's heart failure treatment (aggressive diuresis) directly conflicts with preserving kidney function. How do you approach this treatment dilemma? What role do the patient's goals play?

2. **Polypharmacy Management:** In Case 2, multiple medications contributed to delirium. How would you approach deprescribing with the family, particularly the home sleep medication the patient has taken for years?

3. **Prognosis Communication:** In Case 3, how would you respond if the family says "Don't tell her how serious it is - it will take away her hope"?

4. **Discharge Planning:** For Case 2, the patient cannot return to independent living. How would you approach this conversation with the patient and daughter who expected her to go home?

5. **Goals of Care:** What is the difference between a patient saying "I don't want to suffer" versus "I want everything done"? How do these statements guide your treatment recommendations?
