Plain English Summary
Background and study aims
Heart failure (HF) is associated with a high mortality and morbidity, reduced quality of life, and increasing health care costs in Europe as well as across the world. The prescription of evidence-based therapies recommended by guidelines is the most effective way of ensuring that patients receive high-quality and optimal care. Surveys of patients with HF often provide descriptions of the clinical characteristics and management of patients and of outcomes, but we lack data on the use of guideline-recommended therapies in all potentially eligible patients. This is the aim of this study.
Who can participate?
Adult outpatients with chronic HF and left ventricular systolic dysfunction (LVSD).
What does the study involve?
Physician selection is based on the best available sources, either local or regional, concerning the epidemiology and medical care data, including available market data and epidemiological surveys. A general target of 10-20 consecutive patients per investigator was used ensuring the best possible representative inclusion of the HF population in each practice setting.
Information collected includes: demographics; medical history; risk factors and lifestyle; results of physical examination; current symptoms; laboratory values if available; and current medical treatments. Adherence to evidence-based pharmacologic treatments recommended by guidelines will be determined by calculating the adherence score, taking into account the treatment eligibility criteria and the existence of contraindications to drugs based on the international guidelines on management of HF.
What are the possible benefits and risks of participating?
This information is expected to be important to physicians, care providers, and health services, by identifying gaps between evidence and practice and areas for improvement in the post-discharge care of outpatients with chronic HF and LVSD. Physicians have been instructed to continue management and treatment of patients according to their usual practice and the new international guidelines for the management of HF. No specific tests or therapies will be prescribed as part of this survey, and the management of patients will be completely left to the discretion of participating physicians.
Where is the study run from?
547 centres from 36 countries
When is the study starting and how long is it expected to run for?
January 2013 to September 2018

QUAlity of adherence to guideline recommendations for LIfe-saving treatment in heart failure: an international surveY: an observational study
1. Assess clinical characteristics and management of outpatients with heart failure
2. Focus on how monitoring of disease status can be used to guide treatment
3. Evaluate the prescription of recommended therapeutic options in eligible patients
4. Assess adherence to the new European Society of Cardiology guidelines for the management of heart failure
Ethics approval obtained in every country in accordance with local regulations. All 557 centres obtained ethics approval before recruitment of the first participant (the first approval was obtained on 10/06/2013 from the Ethics Committee at the National Institute of Cardiovascular Diseases, Slovakia; approval for the last site was on 20/09/2014 from McGill University Health Centre Biomedical D, Canada).
