[Methods and development of therapy recommendations for symptom control in palliative medicine].

The Drug Commission of the German Medical Association has decided to develop treatment guidelines for palliative care. A series of systematic reviews was commissioned to evaluate the evidence for interventions of common symptoms that burden patients and care givers. A common methodology for all reviews is described in this paper. The methodology was based on the work of the European Palliative Care Research Collaborative. Standardized search strategies were identified in PubMed and Embase and these templates were then adapted by the authors of the reviews according to their needs. The template included the target group (patients and disease entities), indications (symptoms) and interventions (medicines and classes of medicines). Target groups included search terms on palliative or hospice care, cancer, neurodegenerative diseases, HIV/AIDS as well as cardiac and pulmonary failure. The number of relevant hits was surveyed in the first 40 hits in some exemplary searches. This was used for fine tuning the search templates and to optimize the search strategy in order to achieve the highest possible yield with the minimum possible effort. The review series was performed using this search strategy. Every review graded the quality of the included evidence following categories of the Drug Commission of the German Medical Association. Based on these results and recommendations the treatment guidelines will be formulated which will offer concise and evidence-based guidelines for general palliative medicine, offering primary care givers guidance for adequate palliative care in severely ill and dying patients.
