Guidelines on the Diagnosis and Management of Pericardial Diseases Executive SummaryThe Task Force on the Diagnosis and Management of Pericardial Diseases of the European Society of Cardiology

Guidelines and Expert Consensus documents aim to present all the relevant evidence on a particular issue in order to help physicians to weigh the benefits and risks of a particular diagnostic or therapeutic procedure.They should be helpful in everyday clinical decision-making.A great number of Guidelines and Expert Consensus Documents have been issued in recent years by different organisations, the European Society of Cardiology (ESC) and by other related societies.By means of links to web sites of National Societies several hundred guidelines are available.This profusion can put at stake the authority and validity of guidelines, which can only be guaranteed if they have been developed by an unquestionable decisionmaking process.This is one of the reasons why the ESC and others have issued recommendations for formulating and issuing Guidelines and Expert Consensus Documents.In spite of the fact that standards for issuing good quality Guidelines and Expert Consensus Documents are well defined, recent surveys of Guidelines and Expert Consensus Documents published in peer-reviewed journals between 1985 and 1998 have shown that methodological standards were not complied within the vast majority of cases.It is therefore of great importance that guidelines and recommendations are presented in formats that are easily interpreted.Subsequently, their implementation programmes must also be well conducted.Attempts have been made to determine whether guidelines improve the quality of clinical practice and the utilisation of health resources.The ESC Committee for Practice Guidelines (CPG) supervises and coordinates the preparation of new Guidelines and Expert Consensus Documents produced by Task Forces, expert groups or consensus panels.The Committee is also responsible for the endorsement of these Guidelines and Expert Consensus Documents or statements.
