Core Outcome Measures in Effectiveness Trials

Developing a Core Outcome Set for Traditional Chinese Medicine on Treatment of Ischemic Stroke

General Information

In recent years, cerebrovascular diseases have been the top leading causes of death in China. There are more than 7 million patients with cerebrovascular diseases in China, of which about 70% are ischemic stroke. In clinical practice, Traditional Chinese medicine (TCM) has a unique effect in the treatment of ischemic stroke. An increasing number of trials had been conducted in this area. However, these clinical trials and systematic reviews have failed to confirm the effectiveness of TCM, because the heterogeneous reporting of outcomes in these trials has hindered synthesizing the results in meta-analyses, which reduce the value of trials. Meanwhile, it may exist risk of selective outcome reporting bias in clinical trials. The core outcome set of TCM for the treatment of ischemic stroke have not been standardized. The development of a core outcome set (COS) that should be measured in all clinical trials for a specific health condition has been recommended. So it is necessary to develop a COS for ischemic stroke in clinical trials of TCM.
