A Novel Strategy for Recurrent Heart Failure: Planned Hospitalization Before Clinical Worsening: A Retrospective Study of the Kurume-HEARTS Program

This retrospective study demonstrates that the Kurume-HEARTS program, which utilizes planned hospitalizations for structured education and management, significantly reduces total hospitalization costs and length of stay per person-year compared to unplanned admissions for patients with recurrent heart failure.

The Gist

Imagine your heart is like the engine of a very old, very complex car. For most people, this engine runs fine with regular oil changes and a quick check-up at the mechanic once a year. But for some drivers, the engine is so worn out that it keeps sputtering and stalling, forcing them to call a tow truck (the emergency room) constantly.

This is the story of Heart Failure. It's a condition where the heart struggles to pump blood, leading to frequent, scary, and expensive trips to the hospital.

The paper you shared describes a new strategy called the Kurume-HEARTS program. Think of it as a "Preventative Pit Stop" instead of waiting for the car to break down on the highway.

Here is the simple breakdown of what they did and what they found:

1. The Problem: The "Breakdown" Cycle

Usually, when a patient's heart gets worse, they wait until they feel terrible (short of breath, swollen legs) and then rush to the hospital.

• The Analogy: This is like waiting until your car is smoking and the engine is on fire before you call for help. By the time you get there, the damage is severe.
• The Cost: These emergency trips are chaotic. Doctors have to work overtime, use expensive equipment, and keep the patient in the hospital for a long time to cool the engine down. It's incredibly expensive and stressful for the patient.

2. The Solution: The "Scheduled Pit Stop"

The doctors in Kurume, Japan, tried a different approach. Instead of waiting for the car to break, they scheduled regular "pit stops" for their most troubled drivers before the engine failed.

• How it works: If a patient usually gets sick every 6 months, the doctors schedule a planned hospital stay every 4 months.
• What happens there: It's not an emergency. It's a calm, organized week where a whole team (doctors, nurses, dietitians, exercise coaches) works together to:
  • Tune the engine: Adjusting medications to the perfect dose.
  • Teach the driver: Showing the patient exactly how to manage their diet, weight, and symptoms at home.
  • Exercise the engine: Getting the patient moving safely to strengthen their heart.

3. The Results: Smoother Rides, Lower Bills

The researchers compared the "Emergency Breakdowns" (unplanned hospitalizations) with the "Scheduled Pit Stops" (the Kurume-HEARTS program) for the same group of patients.

• The Cost: The "Scheduled Pit Stops" were much cheaper. Because the doctors knew exactly what to do and didn't have to rush, the bill was lower.
• The Time: Patients spent fewer days in the hospital during these planned visits. They didn't have to wait for the engine to cool down; they were already in a stable state.
• The Health: When patients came in for an emergency, their "engine gauges" (blood tests) showed they were in crisis. When they came in for a planned visit, their numbers were much better, meaning they were healthier and more stable.

4. The Big Takeaway

The study found that by being proactive (planning ahead) rather than reactive (waiting for a crisis), you can save money and reduce stress.

The Metaphor:
Think of it like home maintenance.

• Unplanned Hospitalization: Your roof leaks, the ceiling collapses, and you have to call an emergency contractor at 2 AM to fix a disaster. It costs a fortune and ruins your day.
• Planned Hospitalization: You hire a contractor to come every few months to check the shingles, clean the gutters, and fix small cracks. It costs less, takes less time, and you never have a collapsed ceiling.

Why This Matters

For patients with severe heart failure, the "emergency room" route is often the only option they know. This study suggests that if we can get these patients into a structured, planned program, we can:

1. Save money for the healthcare system.
2. Save time for the patients (less time in a hospital bed).
3. Improve quality of life by keeping the "engine" running smoothly for longer.

In short: Don't wait for the smoke to see the fire. Schedule the check-up before the smoke appears.

Technical Summary

1. Problem Statement

Heart failure (HF) imposes a massive global burden, characterized by high rates of rehospitalization due to acute decompensation. These unplanned hospitalizations are the primary driver of morbidity, mortality, and healthcare costs. While guideline-directed medical therapy (GDMT) and outpatient self-management education have improved outcomes, a subset of patients with recurrent HF continues to experience frequent decompensations despite standard care. These patients often present to the hospital in a state of severe clinical instability (high congestion, organ dysfunction), necessitating intensive, resource-heavy interventions that result in prolonged stays and elevated costs. There is a lack of structured strategies to proactively manage this high-risk population before they reach a critical decompensation point.

2. Methodology

• Study Design: Retrospective cohort study utilizing a within-patient paired analysis.
• Setting: Kurume University Hospital, Japan.
• Study Period: January 2020 to October 2025 (Data assessed in February 2026).
• Population:
  • Inclusion: Patients aged ≥20 with HF, a history of at least one HF-related hospitalization in the preceding 12 months, and specific needs for enhanced self-care support (e.g., poor adherence, inadequate weight management).
  • Exclusion: Dementia, terminal malignancy, immediate dialysis initiation, or scheduled surgery.
  • Final Cohort: 20 patients (13 men, 7 women; mean age 69.2 years) with heterogeneous etiologies (ischemic, non-ischemic cardiomyopathy, valvular, pulmonary arterial hypertension).
• Intervention (Kurume-HEARTS Program):
  • A structured program of planned hospitalizations scheduled proactively (e.g., every 4–12 months) based on the patient's prior recurrence interval, rather than waiting for acute symptoms.
  • Multidisciplinary Approach: Included physicians (disease management, medication titration, advance care planning), dietitians, pharmacists, physiotherapists, and nurses.
  • Activities: Intensive education, cardiac rehabilitation, medication optimization, and reassessment of hemodynamics/volume status.
• Comparison: Each patient served as their own control, comparing outcomes during unplanned hospitalizations (emergency admissions for exacerbation) versus program-based planned hospitalizations.
• Endpoints:
  • Co-Primary: Total hospitalization cost per person-year and total length of stay (LOS) per person-year.
  • Secondary: Per-admission cost, per-admission LOS, admission frequency, and NT-proBNP levels at admission.
• Cost Calculation: Utilized Japan's Diagnosis Procedure Combination (DPC) system, encompassing bundled payments and fee-for-service components (excluding oral medication fees).
• Statistical Analysis: Wilcoxon signed-rank test for paired comparisons; effect sizes reported as Hodges-Lehmann medians with 95% confidence intervals (CI).

3. Key Contributions

• Novel Strategy: Proposes "planned hospitalization" not as a failure of outpatient care, but as a proactive, scheduled intervention to stabilize high-risk patients before clinical deterioration.
• Within-Patient Design: By comparing the same patients' unplanned vs. planned admissions, the study minimizes confounding variables related to patient baseline characteristics.
• Multidisciplinary Integration: Demonstrates a model where inpatient stays are utilized specifically for education, rehabilitation, and GDMT optimization rather than solely for acute crisis management.
• Economic Analysis: Provides specific data on the cost differential between reactive (unplanned) and proactive (planned) care models in the Japanese healthcare system.

4. Results

• Hospitalization Volume: Over a median follow-up of 27.1 months, 135 hospitalizations occurred (69 unplanned vs. 66 program-based).
• Primary Outcomes (Per Person-Year):
  • Cost: Total hospitalization cost was significantly lower during the Kurume-HEARTS program compared to unplanned periods (Median difference: +1,658,000 JPY higher for unplanned; p=0.015).
  • Length of Stay (LOS): Total LOS per person-year tended to be shorter for the program (Median difference: +19.3 days longer for unplanned; p=0.070).
• Secondary Outcomes (Per Admission):
  • Cost per Admission: Significantly lower for planned admissions (Median: 887,000 JPY) vs. unplanned (1,330,000 JPY; p<0.001).
  • LOS per Admission: Significantly shorter for planned admissions (Median: 17.5 days) vs. unplanned (29.2 days; p=0.001).
  • Admission Frequency: No significant difference in the number of admissions per person-year between the two strategies (p=0.950).
  • Clinical Status (NT-proBNP): NT-proBNP levels at admission were significantly higher during unplanned hospitalizations (Geometric Mean Ratio: 1.36; p=0.008), indicating greater clinical instability and congestion at the time of emergency admission.
• Medication Optimization: Following the program, GDMT was optimized in the majority of patients (e.g., SGLT2 inhibitors in 17/20, RAAS inhibitors in 15/20).

5. Significance and Implications

• Clinical Efficiency: The study suggests that scheduled, shorter, and less intensive hospitalizations can effectively manage recurrent HF, preventing the need for prolonged, high-intensity emergency care.
• Economic Impact: While the frequency of admissions did not decrease, the per-admission cost and duration were significantly reduced, leading to a lower total annual cost burden. This indicates that shifting resources toward planned care is more cost-effective than reacting to crises.
• Patient Safety: The lower NT-proBNP levels in planned admissions suggest that patients are admitted earlier in the disease trajectory, avoiding the severe decompensation associated with emergency visits.
• Policy Implications: The authors argue for health policy reforms to reimburse planned hospitalizations for education and rehabilitation as a standard component of HF management, potentially reducing the overall economic burden of heart failure.
• Limitations: The study is single-center, retrospective, and has a small sample size (n=20), limiting generalizability. Long-term mortality and quality of life outcomes were not assessed. Future prospective, multicenter trials are needed to validate these findings.

Conclusion: The Kurume-HEARTS program demonstrates that a proactive strategy of planned hospitalization for education, rehabilitation, and medication titration can significantly reduce the cost and length of hospital stays for patients with recurrent heart failure, offering a viable alternative to the current reactive model of care.
