Quality Assessment of Randomized Controlled Trials on Treatment of Chronic Obstructive Pulmonary Disease in Stationary Phase with Point Application / 中国中医药信息杂志

ABSTRACT

Objective To investigate the current situation of randomized controlled trials (RCTs) on the treatment of chronic obstructive pulmonary disease (COPD) in stationary phase with point application, and provide evidence for clinical practice. Methods Such databases as CNKI, VIP, and CBM were searched from the establishment date to October 2011 to collect the RCTs on the treatment of COPD in stationary phase with point application according to the predefined inclusion criteria. And the quality was assessed by using the Jadad scale, the revised CONSORT statement and other self-defined indexes. Results Among 32 included RCTs, 1 literature scored three points, 8 scored two points, 23 scored one point according to Jadad scale, and no RCT performed the allocation concealment. According to the CONSORT criteria, only one can be prompted randomized trials from the title of the article, 23 from abstracts, 2 literature showed how to determine the sample size, 7 described the method to generate random allocation sequence, only 1 literature mentioned blind method, 15 literature explicitly mentioned syndromes. Conclusion Currently, the methodology and reporting quality of studies on the treatment of COPD in stationary phase with point application are not good enough to provide reliable evidence for clinical practice, and we should improve the quality of our clinical research.
