  • Characteristics of the methodological studies on patient compliance in clinical trials in China

    ObjectivesTo explore the characteristics of Chinese methodological studies on patient compliance in clinical trials so as to provide reference for clinical trial of patient compliance in future.MethodsCNKI, VIP, CBM and WanFang Data databases were electronically searched to collect methodological studies on patient compliance in clinical trials published in Chinese language from January 2000 to December 2018. Two reviewers independently screened literature, extracted data and then, qualitative analysis of document characteristics was then performed.ResultsA total of 84 articles were included, in which 68 were studies on Western medicine and 16 were studies on traditional Chinese medicine (TCM). The results showed that: the quantity of studies on patient compliance increased along with time. However, those in TCM field did not increase. All included studies summarized their strategies to improve patient compliance, however key information for quality evaluation were missing.ConclusionsThere is still a lack of research on how to improve patients’ compliance in clinical trials to ensure the reliability of the results. Existing studies have not systematically and comprehensively explored the influencing factors of patients’ compliance. Clinical trials researchers in China have not focused sufficiently to patients’ compliance and lack the proper methodology to frame studies.

  • Characteristics of the international clinical studies using objective performance criteria

    ObjectivesTo explore the characteristics of the international clinical studies using objective performance criteria (OPC) and provide a reference to design clinical trials and determine external controls.MethodsPubMed, The Cochrane Library and EMbase databases were searched for all clinical studies which used OPC. Two reviewers independently screened literature, extracted data and descriptive analysis was then performed.ResultsA total of 51 English language articles were included. Merely one was published in 2001, and others were published between 2010 and 2018. Twenty-seven articles (27/51, 52.9%) were published between 2017 and 2018, with accumulated impact factors of 411. In the article referring to the reasons for using the objective performance criteria, reasons for using OPC study was primarily the difficulties of randomization and comparison (8/11, 72.7%). Articles with cardiovascular disease and peripheral vascular disease accounted for 86%, and articles on the effectiveness or safety of medical devices accounted for 76.5%. Single-arm trial (40), randomized controlled trials (2), case-control studies (2), case series (5) and diagnostic tests (2) were included. OPCs were mostly derived from the data of clinical trials of other similar products, national standards, specialist association standard and meta-analysis of multiple clinical studies. A total of 27 articles (27/51, 52.9%) used hypothesis testing to compare research results with objective performance goal, and 24 articles (24/51, 47.1%) used the confidence interval method.ConclusionsOPC studies are primarily used for safety intervention and effect evaluation. OPC studies are developing very rapidly, especially in the field of cardiovascular studies. Methodological details are reported reasonably sufficient. Reasons for using OPC study are primarily the difficulties of randomization and comparison. Factors such as source of the OPC, sample size, and comparison method should be taken into account. The application of the OPC can not only solve the difficulties of the implementation of numerous clinical research, but also provide new insights for solving the practical difficulties of clinical research in the real-world.
