The reporting of clinical acupuncture research: what do clinicians need to know?

Attitudes and interests toward research among students at two colleges of acupuncture and Oriental medicine

BACKGROUND

Collaborative input from clinicians of acupuncture and Oriental medicine (AOM) is required for sound AOM research, and AOM training institutions have begun to include research education into their curriculum. However, few attempts have been made to systematically evaluate AOM practitioners' perspectives on the value of research to their profession.

METHODS

We conducted surveys of AOM students at two institutions that have begun to integrate research training into their curriculum, the New England School of Acupuncture and the Oregon College of Oriental Medicine. Surveys were conducted to assess current attitudes regarding the value of research and to serve as a reference point for documenting the impact of ongoing research training programs on these attitudes. Surveys at both institutions were independently developed and administered but shared seven questions that were phrased very similarly. This paper summarizes responses to these questions.

RESULTS

Surveys at both institutions suggest interest in research among AOM students is high in first-year students; students in later years showed a lower level of interest, but the cross-sectional design of this survey does not allow any temporal effects to be inferred. Results also indicate that AOM students believe research is highly relevant to how both the public and the health insurance industry view their system of healthcare but not highly relevant to their own clinical practice of AOM. The belief that research is of limited relevance to clinical practice was associated with widespread belief that scientific methods may not be consistent with the principles of AOM.

CONCLUSIONS

Results of these surveys provide important preliminary information about attitudes of AOM students toward research, and thus the value and future specific needs of research training programs targeting this population. Repeated implementation of validated versions of our surveys are needed to confirm the trends we report and to evaluate the impact of research training programs already in place on AOM students' attitudes toward research.

Redefining the randomized controlled trial in the context of acupuncture research

BACKGROUND

The randomized controlled trial (RCT) is considered the 'gold standard' methodology for evaluating efficacy of an intervention. It has been argued that RCTs cannot be used to examine the effectiveness of acupuncture.

PURPOSE

The purpose of this paper is to examine the applicability of an RCT study design for acupuncture research.

FINDINGS

RCTs would be more effective in studying acupuncture if study participants were randomized to groups based on the acupuncture diagnosis and not solely on the Western diagnostic criteria. Treatments must also be standardized somewhat to ensure replicability of the study and the information it provides. Blinding is not absolutely necessary for a good-quality RCT; however, if used, control groups need to be standardized and sham techniques evaluated to ensure accurate interpretation of results.

CONCLUSIONS

With these factors combined, it is possible to greatly increase internal and external validity in acupuncture RCTs.

Clinical Research on Acupuncture: Part 2. Controlled Clinical Trials, an Overview of Their Methods

There is almost universal agreement that the quality of clinical trials of acupuncture is poor. There is an urgent need to improve their quality. The author develops here a list of 45 criteria important in the design, implementation, and writing up of controlled clinical acupuncture trials. This list has been compiled after examining the quality assessment criteria used in meta-analyses and systematic reviews of acupuncture, general publications on clinical trial designs and methodological considerations specific to acupuncture trials. Each criterion is discussed with recommendations about use and implementation. Additionally, each criterion is discussed relative to their importance in three types of acupuncture trial, acupuncture versus sham acupuncture, acupuncture versus standard therapy and acupuncture versus no treatment or wait-list. It is hoped that this exploration and systematic presentation of the 45 criteria will contribute to improving the quality of clinical trials of acupuncture. Improved trial quality will lead to greater ease interpreting the results of trials, especially in systematic reviews.
