Evidence-based health care (EBHC) has consistently been attacked by opponents for being perniciously reductive. Although these attacks are overwhelmingly framed as critiques of evidence-based medicine, they standardly target the research wing of EBHC upon which evidence-based medicine is dependent, and increasingly extend to adjacent health care disciplines, such as nursing. One of the most persistent forms this line of attack has taken is the allegation that EBHC, with its emphasis on the hierarchy of evidence, grounded in the use of randomized controlled trials, and the clinical guidelines developed on their basis, fails to recognize the patient as the complex self she is, treating her instead as merely a quantifiable, medical-scientific object. By reducing the patient to certain quantifiable dimensions, the patient as self is allegedly 'erased'. In short, the complaint is that an evidence-based approach to health care has no room for the self. Contrary to this persistently held view, it is argued here that EBHC does have room for the self. Review of these critiques suggests they can be categorized into two groups: soft critiques and strong critiques. Soft critiques tend to take a more measured tone grounded in empirical concerns about the dangers of an evidence-based approach to health care, whereas strong critiques tend to make sweeping claims grounded in theoretical commitments to anti-foundationalist philosophical frameworks. While both soft and strong critiques ultimately fail to make the case that EBHC has no room for the self, the empirical concerns of soft critiques nevertheless present a challenge EBHC advocates would do well to take seriously and address.
循证医疗保健(EBHC)一直遭到反对者的抨击,被指具有有害的简化倾向。尽管这些抨击绝大多数被视为对循证医学的批评,但它们通常针对的是循证医学所依赖的EBHC的研究分支,并且越来越多地延伸到相邻的医疗保健学科,如护理学。这种攻击最持久的形式之一是声称,EBHC强调以随机对照试验的使用为基础的证据等级制度以及在此基础上制定的临床指南,没有将患者视为她真实的复杂个体,而是仅仅将其当作一个可量化的医学科学对象。通过将患者简化为某些可量化的维度,作为个体的患者据称被“抹去”了。简而言之,抱怨的是基于证据的医疗保健方法没有给个体留有余地。与这种长期持有的观点相反,本文认为EBHC确实给个体留有余地。对这些批评的审视表明,它们可以分为两类:温和批评和激烈批评。温和批评往往采取更审慎的语气,基于对循证医疗保健方法危险性的实证担忧,而激烈批评往往基于对反基础主义哲学框架的理论承诺提出一概而论的主张。虽然温和批评和激烈批评最终都未能证明EBHC没有给个体留有余地,但温和批评的实证担忧仍然提出了一个挑战,EBHC的倡导者最好认真对待并加以应对。
