Case reports have had a varying level of recognition as a source of evidence throughout the history of medicine. In recent years, there has been a revival of interest in clinical case reports in both conventional and complementary medicine. There is a need to further improve the reporting quality of clinical case reports of different Complementary and Alternative Medicine (CAM) therapies. To provide an overview of the different objectives for clinical case reports, identify those that are most relevant for CAM, and to develop a conceptual framework for purpose orientated clinical case reporting guidelines for CAM therapies. To practically illustrate the chosen approach by developing a clinical case reporting guideline for homeopathic cases. The various objectives of clinical case reports were described by Prof. Milos Jenicek, and the potential relevance of these objectives for CAM were discussed and graded by a mixed panel of experts. A conceptual framework for developing clinical case reporting guidelines for CAM treatments with specific objectives is proposed. The aim is to integrate both 'generic' and 'CAM therapy specific' quality items. This framework has been practically applied to the development of a reporting guideline for clinical case reports in homoeopathy which will be reported in a second article. An overview is given of the clinical case reporting literature. The conceptual framework for the development of purpose orientated CAM clinical case reporting guidelines is presented. This framework is based on alignment with the recently published 'generic' CARE guideline for reporting of clinical case reports, whilst addressing the CAM specific elements at the same time. The scope and importance of clinical case reporting guideline development in CAM is illustrated. A conceptual framework for developing CAM specific clinical case reporting guidelines was established. It has been implemented using homoeopathy as an illustration, and this will be reported in a separate article. Further improvements in clinical case reporting in CAM will greatly contribute to CAM research and education, as well as to improved patient care.
