In a randomized single-center study of prayer in coronary care unit patients, Harris et al6 were supported by the hospital institutional review board (IRB) to conduct the study without obtaining informed consent from patients. The concern leading to this design element was a deep and thoughtful one: patient awareness that a study of prayer was ongoing might profoundly change the spiritual landscape being studied. The IRB was duly consulted, and the study design was approved based on the IRB’s conclusion that this therapy “could not possibly do harm.” Although for personal or cultural practices assumptions of Divine benevolence may be both relevant and satisfactory, for clinical research, such an assumption could only be considered scientifically naive as in the history of medicine there has never been a healing remedy that was actually effective without having potential side effects or toxicities.
Rigorous thinking is not an indictment of prayer or prayer’s potential healing power. Rather, it is respect for the complex, redundant, and relatively frail aspects of human physiology in the setting of coronary revascularization. In medical school, almost 30 years ago, we were taught to define health as a state of equilibrium and to understand disease as a fundamental disequilibrium. Protocol addition of an influence we do not mechanistically understand into a physiologic or even “mind-body-spirit” disequilibrium such as heart disease obliges open minded clarity in interpreting the results, even if the results are not what we intend or expect. Both ethically and scientifically, this approach should be no different for the clinical study of intercessory prayer than for any other novel therapeutic.
In STEP, the safety of patients and related ethical obligations to study subjects were conducted, like so much of the study methodology, at the very highest level. Informed consent was required, and data and safety monitoring board oversight was provided. The data, on the other hand, proved to be counterintuitive. The assumption imbedded in the analysis plan was that blinded prayer would be effective and unblinded prayer even more effective, with expected complication rates of 50% in the standard care group, 40% in the blinded prayer group, and 30% in the unblinded prayer group–exactly the opposite of what was actually observed. In the interpretation of obviously counterintuitive findings as “what may have been chance,” the STEP investigators have allowed cultural presumption to undermine scientific objectivity. Leading researchers such as the STEP team should be underlining the imperative that mechanistically undefined “frontier” therapy research–even well intentioned intercessory prayer–must be scrutinized for safety issues at an equal or even higher level than efficacy measures if medically important and useful knowledge in this arena is to truly step forward.
So it seems the scientific community is not as impressed with the results as those who gleefully throw around headlines and sound bites.
