About
Heart failure (HF) is characterized by high mortality, poor quality of life and frequent hospitalizations. The effectiveness of out-patient care for HF patients is unsatisfactory. Therefore the solutions that enable effective monitoring and assessment of HF patients' clinical status become priority in treatment strategy. The applicant proposes to develop a model of care for HF patients based on modern non-invasive diagnostic tools and telemedicine. Clinical evaluation will be based on i.e. impedance cardiography, a simple non-invasive method of hemodynamic monitoring, including assessment of heart rate, blood pressure, left ventricular stroke volume, chest and total fluid status. The telemedicine system will enable rapid, appropriate to the patient's clinical status, therapeutic decision undertaken remotely by specialist. Implementation of the proposed model of care will contribute to a significant improvement in prognosis of HF patients (through i.e. improved access to specialist consultation, the early diagnosis of the deterioration of HF and the optimization of treatment). The significant economic, social and scientific benefits related to the project are also expected.
Full description
Treatment of patients with heart failure (HF) is a great challenge for contemporary medicine. HF frequency in European population is assessed for 0.4-2%. This disease is characterized by high morbidity and mortality rate, poor quality of life and frequent hospitalizations. Along with the medicine progress, in particular in the scope of acute coronary syndromes treatment, the number of HF patients is constantly growing. The essential problem connected with HF is its progress course and an increasing rate of subsequent hospitalizations (approximately 30% of hospitalizations are the repeated ones). It is estimated that the costs of hospital stays constitute nearly 2/3 of healthcare costs provided for HF patients.
It has been estimated that the prevalence of HF will increase by 25% and its direct costs by 215% in the next 20 years. The prognosis in HF is closely connected with the progression of the disease defined in accordance with the NYHA (New York Heart Association) functional classification. The yearly mortality rate among each NYHA class is: class 1 - up to 10%, class 2 - 10-20%, class 3 - 20-40%, class 4 - mortality 40-60%. Over a half of the patients with symptomatic HF die within 4 years of observation.
In the AMULET study we we will merging the interventions that so far turned out to be effective (specialist counselling, phone counselling programmes and telemonitoring). Therefore, we created of ambulatory care points for HF patients, which would be equipped with diagnostic devices (impedance cardiography and body composition analyser (bioimpedance scale)), assessing the most important clinical parameters. Ambulatory care point will be operated by a trained nurse, under a telemetry supervision of a specialist.
The following parameters were identified as the indicators of treatment effects: heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), thoracic fluid content (TFC) and its change (delta TFC), change of body mass and total body water (delta TBW).
The telemedicine solutions will strongly support the proposed system. The clinical data will be automatically entered into an interactive system (database), which will send information to a supervising cardiologist, in accordance with the previously implemented recommendation support module (RSM). Regarding RSM indications remote specialist recommendation will be generated (e.g. maintenance or modification of treatment, referral to hospital).
The proposed approach will satisfy ESC recommendations on long-term management: plan follow-up strategy (including plan to up-titrate/optimize dose of disease-modifying drugs); improvement in symptoms, quality of life and survival; prevention of readmissions; management programme; education and appropriate lifestyle adjustments.
