Applying the Delphi Method to the New Integrative Homeopathic Cancer Care Recommendations of the International Homeopathic Society for Supportive Care in Oncology (SHISSO)

Background: Since 2017, the International Homeopathic Society for Supportive Care in Oncology (SHISSO) has been developing thirty homeopathic integrative care guidelines using the “recommendations by formalised consensus” method. It led to the publication of guidelines according to patient symptoms. However, challenges have emerged. How can we benefit from the experience of experts from other parts of the world? How can we avoid a situation where certain experts take the lead and influence others? How can we be sure that our recommendations meet the consensus of all the different homeopathic schools? Methods: The Delphi method, a qualitative and quantitative method based on open and closed questions, was used by a group of analysts and sent anonymously to a panel of international experts, representing five continents and different homeopathic schools of thought. Each question begins with: “If you had to give advice to a colleague, to help a patient you don’t know, with one of the following symptoms, which homeopathic medicine(s) would you suggest as first-line treatment?” Consensus answers (>75% agreement) are retained, while the others are subjected to a second or even third round, each accompanied by a synthesis. Consensus responses are published, while others are rejected. Results: The design of the study is done, the choice of the experts is underway, and the final results are expected to be available for presentation end of 2025. Conclusion: The Delphi method is particularly suited for homeopathic research, as it provides a first level of evidence through expert consensus. This process strengthens homeopathic practice by offering validated recommendations for clinical use and helps justify homeopathic protocols to health authorities. Moreover, it can serve as a precursor to clinical research protocols, ensuring their relevance and feasibility.
