The problem of harmful, unnecessary and neglected pain has been studied extensively in many health care settings over the past decade. Research has documented the incidence of untreated pain, and scholars and advocates have given the problem several names: “public health crisis,” “oligoanalgesia, and “moral failing,” among them. Articles have identified a litany of now familiar “obstacles” or “barriers” to effective pain relief. Each of these individual obstacles or barriers has been the subject of targeted remedial action in at least (...) some context.The checklist approach to improving care for patients in pain, however, is likely to have only limited effect. What really appears to be operating is a complex ecosystem that supports ambivalence, denial, and even suspicion of the circumstance of patients in pain and efforts to treat them. Pain relief in emergency medicine, a relatively new setting for the study of challenges to treating pain, provides a revealing context for viewing discrete obstacles to effective pain management in medicine as part of an integrated environment into which patients with pain enter for treatment.
