Heart failure (HF) is a significant public health concern. Specialized HF clinics provide the optimal environment to address the complex needs of these patients and improve outcomes. The current and growing population of patients with HF outstrips the ability of these clinics to deliver care. Integrated care is defined as health services that are managed and delivered so that people receive a seamless continuum of health promotion, disease prevention, diagnosis, treatment, disease management, rehabilitation, and palliative care services. This approach requires coordination across different levels and sites of care within and beyond the health sector, according to changing patient needs throughout their lives. The spoke-hub-and-node (SHN) model represents an organization of care that works collaboratively with the primary care sector and is highly integrated with community-based multidisciplinary teams of health care professionals and specialty care. The purpose of this article is to analyze the requirements for successful implementation of SHN models. We consider the respective roles of HF clinics, HF nurse specialists, pharmacists, palliative care teams, telemonitoring, and solo practitioners. We also discuss levels of care delivery and the importance of patient stratification and patient flow. The SHN approach has the potential to build on and improve the chronic care model (CCM) to deliver centralized services to preserve high-quality patient-centred care at affordable costs. 相似文献

Protein-losing enteropathy (PLE) is a chronic condition involving multiple organ systems that may develop any time following Fontan completion. The pathogenesis of PLE is complex and multifactorial. Chronic venous hypertension, low cardiac output, and abnormal lymphatics may all play a role in the pathogenesis of PLE. Common signs and symptoms include chronic diarrhea, abdominal pain, and ascites. Diagnosis is based on the presence of signs and symptoms in addition to hypoalbuminemia and elevated stool alpha 1 antitrypsin. Early identification and a comprehensive approach to evaluation and treatment are important, as they may affect survival. The initial evaluation should include cardiac catheterization for hemodynamic assessment. Although an evidence base for treatment is lacking, various medical, interventional, and surgical approaches have been described with variable degrees of success. Commonly used therapies include nutritional support, diuretics, subcutaneous unfractionated heparin, budesonide, and sildenafil. Limited data exist for Fontan conversion or takedown. Assessment for heart transplantation should be considered. PLE mortality is high—approximately 50%—but may be mitigated by aggressive investigation and management. The evolving understanding of the role of lymphatics in the pathophysiology of PLE and the emerging role of interventional lymphatic procedures may further improve outcomes in this patient population. 相似文献
