Creating evidence for naturopathic nursing interventions in oncology - a systematic approach

Background: Nurses working in oncology use a wide range of naturopathic interventions in their daily practice to alleviate symptoms and improve the quality of life of oncological patients. However, there is no external evidence for many of these interventions. Due to a lack of scientific studies in the field, the aim of the project described here is to develop a standardized procedure to generate evidence on naturopathic interventions, on the basis of which recommendations may be derived for nursing practice. Method: The systematic procedure presented here was developed by the working group (WG) Integrative Nursing in Oncology over a period of four years in an iterative process. This process is based on the expert panel members' experience with the development of guidelines and/or quality instruments such as practice standards. Result: The systematic methodological approach presented here consists of three successive steps where internal and external evidence have been combined: a scoping review, a structured consensus process with oncology nurses to collect and evaluate naturopathic interventions, and finally a further supplementary literature review based on additional findings of the consensus conference. The procedure was successfully carried out for mucositis, insomnia, fatigue, hand-foot syndrome and chemotherapy-induced polyneuropathy. Conclusion: Through the step-by-step synthesis of internal evidence and the best available external evidence, the evidence base for naturopathic nursing interventions in oncology can be generated and practice recommendations derived. The procedure represents a successful theory-practice transfer through structured cooperation between (nursing) scientists and nursing practitioners. In terms of the AWMF classification, the practice recommendations developed in the process described fall somewhere in between an S1 guideline (informal consensus of an expert group) and an Ste guideline (evidence-based).
