Guidelines and Expert Consensus Documents summarize and evaluate all currently available evidence on a particular issue with the aim to assist physicians in selecting the best management strategies for a typical patient, suffering from a given condition, taking into account the impact on outcome, as well as the risk/benefit ratio of particular diagnostic or therapeutic means. Guidelines are no substitutes for textbooks. The legal implications of medical guidelines have been discussed previously. A great number of Guidelines and Expert Consensus Documents have been issued in recent years by the European Society of Cardiology (ESC) as well as by other societies and organizations. Because of the impact on clinical practice, quality criteria for development of guidelines have been established in order to make all decisions transparent to the user. The recommendations for formulating and issuing ESC Guidelines and Expert Consensus Documents can be found on the ESC website (http://www.escardio.org/knowledge/guidelines). In brief, experts in the field are selected and undertake a comprehensive review of the published evidence for management and/or prevention of a given condition. Unpublished clinical trial results are not taken into account. A critical evaluation of diagnostic and therapeutic procedures is performed including assessment of the risk/benefit ratio. Estimates of expected health outcomes for larger societies are included, where data exist. The level of evidence and the strength of recommendation of particular treatment options are weighed and graded according to predefined scales, as outlined in Tables 1 and 2 . View this table: Table 1 Classes of recommendations View this table: Table 2 Levels of evidence The experts of the writing panels have provided disclosure statements of all relationships they may have which might be perceived as real or potential sources of conflicts of interest. These disclosure forms are kept on file at the European Heart House, headquarters of the ESC. Any changes in conflict of interest that arise …

Cancer patients have physical, social, spiritual an emotional needs. They may suffer from severe physical symptoms, from social isolation and a sense of spiritual abandonment, and emotions such as sadness and anxiety, or feeling of deception, helplessness, anger and guilt. In some of them, the disease is rapidly progressive and they ultimately die. Their demanding care evokes intense feelings in health care providers, the more so since these incurable patients represent a challenge, which can be characterized as one of 'medical omnipotence'. It may be assumed that the way health care providers cope with these circumstances profoundly influences the way these patients are cared for. Attitudes regarding the emerging heterogeneous movement of palliative and supportive care and its different models of implementation can be viewed form this vantage point. Here we look at these interrelations and discuss the potential pitfalls if they are ignored and remain unexamined.
