[Expert consensus on Tibetan medicine diagnosis and treatment for high altitude polycythemia].

ABSTRACT

High altitude polycythemia(HAPC) is one of the most common chronic high-altitude diseases and a prominent public health issue in the Qinghai-Xizang Plateau region of China. Tibetan medicine has provided a safe and effective treatment approach for HAPC, but there is currently no expert consensus on Tibetan medicine diagnosis and treatment for the disease. This consensus followed the principles of evidence-based medicine and learned the procedure and methods of Technical specifications on developing expert consensus for clinical practice guideline in traditional Chinese medicine recommended by China Association of Chinese Medicine. Five clinical issues were identified through literature search, expert interviews, clinical research, and conference consensus. The PICO principle was used for evidence retrieval, screening, and synthesis, and the opinions of experts on high-altitude diseases and cardiovascular and cerebrovascular diseases from major Tibetan medical institutions in China, as well as some traditional Chinese medicine(TCM), western medicine, and evidence-based experts, were widely solicited. Recommendations and consensus suggestions were formed through one expert consensus meeting and two rounds of Delphi expert questionnaire surveys. The consensus included disease diagnosis, etiology and pathogenesis, syndrome classification, clinical treatment, outcome evaluation, prevention and care, and other contents. Therapies for HAPC included Tibetan medicine treatments based on syndrome differentiation, single formula or patent medicine, and external treatment. Each treatment had corresponding levels of evidence and recommendations. This consensus was guided by solving clinical problems, combining disease diagnosis and syndrome differentiation and highlighting the characteristics and advantages of Tibetan medicine, with a view to promoting the standardization of Tibetan medicine diagnosis, treatment, and research on HAPC and improving the level of prevention and treatment.
