Johnston, M. F., Hays, R. D., Subramanian, S. K., Elashoff, R. M., Axe, E. K., Li, J. J., . . . Hui, K. K. (2011). Patient education integrated with acupuncture for relief of cancer-related fatigue randomized controlled feasibility study. BMC Complementary and Alternative Medicine, 11, 49.
This small pilot study had two objectives: (1) to design a strategy for recruitment tailored to the institutional environment and therapeutic intervention and (2) to collect evidence of preliminary effects.
In a two-part intervention, patients were first taught to improve self-care with regard to exercise, nutrition, and cognitive-behavioral techniques over a four-week period. They were then provided with eight weekly 50-minute acupuncture sessions. This therapeutic protocol references a conceptual framework derived from two theories—Social Cognitive Theory and Integrative Medicine Theory—but did not provide a description of the theory to match the interventions (exercise, nutrition, cognitive therapy, or acupuncture) with conceptual variables in the model.
This was a randomized, controlled feasibility study.
Failure of the recruitment methods led to the development of a tailored recruitment strategy. The intervention was said to be associated with a 2.38-point decline in fatigue (BFI) (90% confidence interval [0.586, 5.014]; p < 0.10). Differences in perceived cognitive dysfunction outcomes were not statistically significant between the two groups over time. The authors talked about using a pooled standard deviation for the BFI at baseline to compare the means of the two groups to determine the effect size.
An effective recruitment strategy is necessary for the execution of any randomized, controlled trial. The conceptual framework integrating social cognitive theory and integrative medicine was not effectively operationalized.
Investigation into outcomes attributed to specific patient education interventions might first be warranted before blending such an educational intervention with a complimentary/alternative therapy studying efficacy on cancer-related fatigue.
