Perspectives in biology and medicine

Narrative is ever present in medicine and is an integral aspect of the doctor and patient relationship. Although theoretical discussions of narrative medicine and narrative ethics are important, they may serve to reify the patient's story, to make it a specific entity. In practice, the patient's story unfolds in the moment of communication depending on the individuals and the circumstances; the story is not an "object." Patients' narratives heard in clinical settings are often limited by physician behaviors, especially the tendency of physicians to control the interaction with the patient. ⋯ If the patient's narrative is not heard fully, the possibility of diagnostic and therapeutic error increases, the likelihood of personal connections resulting from a shared experience diminishes, empathic opportunities are missed, and patients may not feel understood or cared for. The practice of mindfulness--moment-to-moment, nonjudgmental awareness--opens a doorway into the patient's story as it unfolds. Such mindful practice develops the physician's focus of attention and offers the possibility for a meaningful and important narrative to arise between patient and physician.

Despite the recent blossoming of rigorous research into placebo mechanisms and the long-standing use of placebos in clinical trials, there remains widespread and profound misunderstanding of the placebo response among both practicing physicians and clinical researchers. This review identifies and clarifies areas of current confusion about the placebo response (including whether it exists at all), describes its phenomenology, and outlines recent advances in our knowledge of its underlying psychological and neural mechanisms. ⋯ In addition, this subfield of placebo research offers a specific neural circuit hypothesis capable of being integrated with equally rigorous experimental work on the psychological (including social psychological) and clinical levels. In this sense, placebo analgesia research bears all the marks of a genuine multilevel interdisciplinary research paradigm in the making, one that could serve as a model for research into other kinds of placebo responses, as well as into other kinds of mind-body responses.

The randomized controlled trial (RCT) is not a gold standard: it is a good experimental design in some circumstances, but that's all. Potential shortcomings in the design and implementation of RCTs are often mentioned in passing, yet most researchers consider that RCTs are always superior to all other types of evidence. ⋯ This has important consequences for research methodology, for quality of care in clinical medicine, and--especially--for research funding policy. Because every study design may have problems in particular applications, studies should be evaluated by appropriate criteria, and not primarily according to the simplistic RCT/non-RCT dichotomy promoted by some prominent advocates of the evidence-based medicine movement and by the research evaluation guidelines based on its principles.
