Methodological issues in trials of complementary and alternative medicine interventions
Preliminary EvidenceIn Plain Language: cancer pain, explained
Complementary and alternative medicine (CAM) use is widespread among cancer patients. Information on safety and efficacy of CAM therapies is needed for both patients and healthcare providers. Well-designed randomized clinical trials of CAM therapy interventions can inform both clinical research and practice. The aim of this study was to review important issues that affect the design of randomized clinical trials for CAM interventions. Using the methods component of the Consolidated Standards for Reporting Trials as a guiding framework and a National Cancer Institute-funded reflexology study as an exemplar, methodological issues related to participants, intervention, objectives, outcomes, sample size, randomization, blinding, and statistical methods were reviewed. Trials of CAM interventions designed and implemented according to appropriate methodological standards will facilitate the needed scientific rigor in CAM research. Interventions in CAM can be tested using proposed methodology, and the results of testing will inform nursing practice in providing safe and effective supportive care and in improving the well-being of patients.
Key Findings: what this systematic review found about cancer pain
- ✓Well-designed randomized clinical trials are necessary to provide reliable information on the safety and efficacy of complementary and alternative medicine therapies for cancer patients and healthcare providers.
- ✓Methodological rigor in CAM research requires careful attention to design components including participant selection, intervention standardization, outcome measurement, sample size calculation, randomization procedures, blinding protocols, and appropriate statistical analysis.
- ✓CAM interventions can be scientifically tested using established methodological standards when trials are designed according to frameworks like the Consolidated Standards for Reporting Trials.
What This Means for You
This paper provides a framework for evaluating CAM research quality, but it doesn't report reflexology results; look for actual reflexology trials that follow these methodological standards when assessing evidence for reflexology's effectiveness.
What This Means for Practitioners
Use this paper's methodological framework to understand the rigorous study design standards your reflexology practice should support or expect from published research.
