Guide for recommendations on specific drug-related off-label treatment in palliative care: A Group Delphi process
Abstract Background The use of drugs beyond their authorisation label, i.e. off-label-use, is common practice in palliative care with over 70% of off-label-use having little or no scientific support. Recommendations for off-label-use are essential to increase the safety of drug therapy and thus patient safety. The aim was to develop a guide for preparing and consenting drug-specific recommendations for off-label-use in palliative medicine.Methods Group Delphi Study with three rounds and a prior online survey. Participants represented professional groups working in palliative care involved in direct patient care and/or drug management (doctors, pharmacists, nurses) and various care settings (inpatient/community, university/non-university). Furthermore, representatives of relevant professional associations, experts with academic, non-clinical background and experts with international expertise were invited.Results For the preliminary online-survey 18/20 invited participants returned 18 questionnaires. Six domains, including identification of drugs, drug uses, assessment of evidence, formulation, consensus and updating of recommendations were generated and eventually 22 statements were included in the Group Delphi process. 15 experts participated in this consensus process. In combination with the survey results, consensus was achieved over a 28 statements after 3 Delphi rounds.Conclusions The resulted systematic approach for preparing and consenting drug-specific recommendations for off-label-use will allow to develop such recommendations with transparent and reproducible monographs. This will help to increase treatment quality and patient safety as well as security of decision-making in palliative care. The developed guide is part of a larger project aiming to provide therapy recommendations for areas that have little or no scientific evidence to date.
