Effects of a Multidisciplinary Integrated Care Model on Care Outcomes in Patients With Heart Failure With Preserved Ejection Fraction (MICM-HFpEF)
A Prospective Quasi-Experimental Study With Historical Control to Evaluate the Effects of a Multidisciplinary Integrated Care Model on Care Outcomes in Patients With Heart Failure With Preserved Ejection Fraction
Heart failure with preserved ejection fraction (HFpEF) accounts for approximately half of all heart failure cases and is associated with frequent hospitalizations, poor quality of life, and limited effective treatment options. Fragmented, single-discipline care often fails to address the multiple comorbidities and self-management needs of this population.
This study evaluates a Multidisciplinary Integrated Care Model (MICM) for patients with HFpEF, delivered by a coordinated team including cardiologists, case managers, pharmacists, dietitians, and rehabilitation specialists. The intervention group will receive structured team-based care, including regular follow-up, medication optimization, dietary and lifestyle counseling, and exercise guidance, in addition to standard cardiology care.
Using a prospective quasi-experimental design with a historical control group, this study compares clinical and patient-reported outcomes between patients receiving the multidisciplinary integrated care model and a historical cohort receiving usual care. The primary aim is to determine whether this integrated care approach improves outcomes such as heart failure-related hospitalization, functional status, and quality of life in patients with HFpEF.

Descrição detalhada
Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous clinical syndrome characterized by signs and symptoms of heart failure with a left ventricular ejection fraction ≥50%. It disproportionately affects older adults and patients with multiple comorbidities, including hypertension, diabetes, obesity, and chronic kidney disease. Despite its high prevalence and disease burden, few pharmacologic therapies have demonstrated consistent benefit in this population, highlighting the importance of non-pharmacologic and system-level interventions.
This study investigates whether a Multidisciplinary Integrated Care Model (MICM) improves care outcomes for patients with HFpEF compared with historical usual care. The MICM intervention integrates the following components:
- Cardiology-led clinical management with guideline-directed medical therapy optimization
- Case management for care coordination, symptom monitoring, and care transitions
- Pharmacist-led medication review and adherence support
- Nutritional counseling tailored to heart failure and comorbidity management
- Structured exercise and cardiac rehabilitation guidance
- Patient and caregiver education on self-management and warning signs
Eligible participants are adults diagnosed with HFpEF (left ventricular ejection fraction ≥50%) who receive care at the study institution. The intervention cohort will be prospectively enrolled and followed under the MICM program, while the historical control cohort will consist of patients who received standard usual care prior to program implementation, matched on relevant baseline characteristics.
Outcomes of interest include heart failure-related hospitalization and emergency visits, all-cause mortality, functional capacity, NYHA functional class, and health-related quality of life. Data will be collected through structured clinical assessments and medical record review at baseline and at scheduled follow-up intervals.
Findings from this study are intended to generate evidence on the effectiveness of multidisciplinary, team-based care models in improving outcomes for patients with HFpEF, and to inform future integrated care program development in similar clinical settings.
