9.5 Comorbidity Screening, Stress Management, and Referral Pathways
Key Takeaways
- The CHFN outline expects routine screening for chronic pain, cognitive impairment, sleep disorders, depression, suicide risk, anxiety, domestic violence, environmental safety, falls, anemia, thyroid dysfunction, gout, and other common comorbidities.
- Any positive answer to PHQ-9 item 9 requires a same-day suicide risk assessment and safety plan, regardless of the total PHQ-9 score.
- Gout flares in heart failure are treated with renally dosed colchicine or a short corticosteroid course rather than NSAIDs, and loop and thiazide diuretics raise uric acid.
- Genetic counseling is indicated for familial or unexplained cardiomyopathy, such as nonischemic dilated cardiomyopathy with a first-degree relative who died suddenly at a young age.
- A referral is complete only when the loop is closed: the patient agrees, access barriers are solved, information is sent, and the nurse confirms the visit happened.
Why Screening Belongs in the Implementation Domain
Many heart failure admissions are triggered or prolonged by problems outside the heart: untreated depression that stops self-care, sleep apnea that worsens atrial fibrillation, NSAIDs taken for pain or gout, falls from orthostatic hypotension, or an unsafe home. The CHFN outline therefore lists specific conditions to screen for and a long list of referral pathways. The nurse's job is to screen systematically, act on positive results, and make sure referrals actually happen.
Screening Checklist
| Condition | Why It Matters in Heart Failure | Practical Screening | Positive Screen: Next Step |
|---|---|---|---|
| Chronic pain | Drives NSAID use and inactivity | 0-10 pain scale or PEG scale (Pain, Enjoyment, General activity) | Non-NSAID plan: acetaminophen, topical agents, physical therapy; pain or palliative referral |
| Cognitive impairment | Undermines medication and weight routines | Mini-Cog, MoCA | Involve caregiver, simplify regimen, neurology or geriatrics referral |
| Sleep disorders | Sleep apnea worsens hypertension, AF, and remodeling; insomnia may reflect orthopnea or nocturia | STOP-Bang, Epworth Sleepiness Scale, questions about orthopnea and nocturia | Sleep medicine referral and sleep study; review diuretic timing |
| Depression | Roughly doubles mortality risk and impairs self-care | PHQ-2, then PHQ-9 | Behavioral health referral; psychotherapy and SSRIs such as sertraline; avoid tricyclics |
| Suicide risk | Hopelessness is common in advanced illness | PHQ-9 item 9; structured tools such as the Columbia Suicide Severity Rating Scale | Same-day risk assessment, safety plan, 988 Suicide & Crisis Lifeline, means safety |
| Anxiety | Common after ICD shocks and hospitalization; worsens symptoms | GAD-2, then GAD-7 | Cognitive behavioral therapy, support groups, behavioral health referral |
| Domestic violence and elder abuse | Unsafe homes block self-care and follow-up | Private, direct questions or tools such as HITS (Hurt, Insult, Threaten, Scream) | Safety planning, social work, National Domestic Violence Hotline (1-800-799-7233), report elder or dependent-adult abuse per state law |
| Environmental safety | Trip hazards, oxygen near smoking or flames, extreme heat without cooling, unsafe medication storage | Home safety checklist, home health assessment | Home modifications, occupational therapy, utility or cooling assistance |
| Fall risk | Orthostatic hypotension, nocturia, frailty, anticoagulation | STEADI three key questions, Timed Up and Go (12 seconds or more is high risk) | Physical therapy, medication review, home safety |
| Anemia | Worsens dyspnea, fatigue, and outcomes | CBC (hemoglobin below 13 g/dL in men or 12 g/dL in women) | Iron studies, bleeding evaluation, IV iron when iron deficient |
| Thyroid dysfunction | Both hyper- and hypothyroidism worsen heart failure; amiodarone causes either | TSH | Treat thyroid disease; monitor amiodarone users about every 6 months |
| Gout | Diuretics raise uric acid; flares lead to NSAID use | Joint symptoms, uric acid | Colchicine (renally dosed) or short corticosteroid course for flares; allopurinol for prevention; avoid NSAIDs |
| Other comorbidities (COPD, atrial fibrillation, kidney disease) | Change diagnosis, drug choice, and prognosis | Spirometry, pulse and ECG or device data, eGFR and urine albumin | Specialist co-management |
Managing Stress and Teaching Stress-Reduction Techniques
Stress raises sympathetic tone, disturbs sleep, and makes self-care harder for patients and caregivers. Screening for anxiety and depression is the first step; practical skills are the second. Teach patients and caregivers techniques they can use at home, such as slow paced breathing, progressive muscle relaxation, guided imagery, mindfulness, gentle movement within the exercise prescription, and pacing daily activities. Connect them with support groups and, when symptoms persist, cognitive behavioral therapy. Section 9.2 lists these techniques in more detail.
Referral Pathways
| Referral | Typical Trigger | What It Provides |
|---|---|---|
| Heart failure disease management program | Recent hospitalization, high readmission risk, GDMT not at target | Structured follow-up, titration, education |
| Social work | Financial, housing, transportation, caregiver, or safety problems | Resource linkage, counseling, benefits |
| Home care | Homebound, complex regimen, recent discharge | Skilled nursing visits, medication and weight checks |
| Nutritionist or dietitian | Sodium or fluid questions, diabetes, CKD diet, cachexia, obesity | Individualized nutrition plan |
| Physical or occupational therapy | Falls, frailty, deconditioning, ADL difficulty | Strength, balance, energy conservation, equipment |
| Cardiac specialist | Electrophysiologist (ICD, CRT, AF ablation), cardiac surgeon (valve, CABG, LVAD), interventional cardiologist (coronary or structural procedures) | Device and procedural evaluation |
| Non-cardiac specialist | Endocrinologist (diabetes, thyroid), psychiatrist, pulmonologist (COPD), nephrologist (advanced CKD), hematologist (anemia, AL amyloidosis) | Comorbidity co-management |
| Cardiac rehabilitation | Stable HFrEF meeting coverage criteria | Supervised exercise and education |
| Genetic counseling | Familial or unexplained cardiomyopathy, young sudden death in the family, suspected hereditary amyloidosis | Genetic testing and family screening |
| Remote patient monitoring | Frequent decompensation, rural location | Daily biometrics or hemodynamic monitoring |
| Sleep specialist | Positive sleep screen, suspected central or obstructive apnea | Sleep study and treatment |
| Hospice or palliative care | High symptom burden, goals-of-care needs, Stage D disease | Symptom relief, advance care planning, end-of-life care |
| Support groups | Isolation, anxiety, new diagnosis, caregiver strain | Peer support (for example, AHA Support Network, Mended Hearts) |
| Case management | Complex care across settings, insurance coordination | Care coordination and utilization support |
| Prescription assistance programs | Unaffordable GDMT | Free or reduced-cost medications, foundation grants, Extra Help |
| Mental health | Depression, anxiety, substance use, suicidal thoughts | Therapy, medication management, crisis care |
Making Referrals Work
- Explain the reason in terms of the patient's goals and get agreement.
- Solve access barriers first: insurance authorization, transportation, cost, and scheduling.
- Use a warm handoff when possible and send the relevant information.
- Close the loop: confirm the appointment happened and that recommendations were received, then update the shared care plan.
Clinical Case Scenario: One Visit, Several Positive Screens
A 69-year-old woman with HFpEF and atrial fibrillation returns 2 weeks after discharge. She has knee pain and has been taking naproxen, her PHQ-9 score is 13 with item 9 marked "several days," her STOP-Bang score is 6, and her Timed Up and Go is 15 seconds.
- Immediate priority: The nurse completes a same-day suicide risk assessment for the positive item 9, develops a safety plan with her, and arranges urgent behavioral health follow-up.
- Medication safety: Naproxen is stopped. The team uses acetaminophen, a topical agent, and physical therapy for knee pain.
- Referrals: Sleep medicine for a sleep study, physical therapy for balance and strengthening, and social work for caregiver support. The nurse schedules a call in 1 week to confirm every referral was completed.
CHFN Exam Traps & Clinical Pearls
Exam Trap: A positive PHQ-9 item 9 outranks every other screening result. The correct answer is a same-day suicide risk assessment, not a routine referral.
Clinical Pearl: Ask about pain and gout at every visit. Unrelieved pain is a common reason patients restart NSAIDs.
Exam Trap: Screening for domestic violence must be done privately, without the partner or family present.
A patient with heart failure completes the PHQ-9 at a clinic visit. The total score is 12, and item 9 ("thoughts that you would be better off dead or of hurting yourself") is scored 1 ("several days"). What is the nurse's priority action?
A patient with HFrEF (eGFR 48 mL/min/1.73 m²) taking furosemide develops an acute gout flare in the right great toe. Which treatment plan is most appropriate?
Which patient has the clearest indication for referral to genetic counseling?
