Healthcare decisions are increasingly being made on research-based evidence, rather than on expert opinion or clinical experience alone. Consequently, the process by which the strength of scientific evidence is evaluated and developed by means of evidence-based medicine recommendations and guidelines has become crucial resulting in the past decade in unprecedented interest in evidence-based medicine and clinical practice guidelines. Systematic reviews, also known as evidence-based technology assessments, attempt to minimize bias by the comprehensiveness and reproducibility of the search for and selection of articles for review. ⋯ The complex processes of guideline development depend on integration of a number of activities, from collection and processing of scientific literature to evaluation of the evidence, development of evidence-based recommendations or guidelines and implementation and dissemination of the guidelines to relevant professionals and consumers. Guidelines are being designed to improve the quality of healthcare and decrease the use of unnecessary, ineffective or harmful interventions. This review describes various aspects of evidence-based medicine, systematic reviews in interventional pain management, evaluation of the strength of scientific evidence, differences between systematic and narrative reviews, rating the quality of individual articles, grading the strength of the body of evidence and appropriate methods for searching for the evidence.

It is the responsibility of clinician investigators to advance clinical knowledge and specifically its application to patient care. Randomized controlled trials remain near the top of the hierarchy of evidence based medicine. The acquisition of evidence based medicine by means of randomized controlled trials presents general difficulties and additional pitfalls specific to interventional treatments. ⋯ To generate clinically useful research results requires an understanding of the mechanics of performing studies and the reporting of methodologies to ensure appropriate interpretation. Placebo arms and sham interventions present serious ethical issues, which must be analyzed on a case by case basis. The conscientious researcher must always abide by the principles of ethical research and the tenets of human subject protection.

Behavioral emergencies are a common and serious problem for consumers, their communities, and the healthcare settings on which they rely, but there is little research to guide provider responses to this challenge. Key constructs such as agitation have not been adequately operationalized so that the criteria defining a behavioral emergency are vague. A significant number of deaths of patients in restraint has focused government and regulators on these issues, but a consensus about key elements in the management of behavioral emergencies has not yet been articulated by the provider community. The authors assembled a panel of 50 experts to define the following elements: the threshold for emergency interventions, the scope of assessment for varying levels of urgency and cooperation, guiding principles in selecting interventions, and appropriate physical and medication strategies at different levels of diagnostic confidence and for a variety of etiologies and complicating conditions. ⋯ To evaluate many of the treatment options in this survey, the experts had to extrapolate beyond controlled data. Within the limits of expert opinion and with the expectation that future research data will take precedence, these guidelines provide some direction for addressing common clinical dilemmas in the management of psychiatric emergencies and can be used to inform clinicians in acute care settings regarding the relative merits of various strategies.

This article examines how patients with cancer construct and legitimate do-not-resuscitate (DNR) orders. Semi-structured interviews with 23 outpatients attending an oncology clinic were tape-recorded, transcribed, and analyzed in accordance with discourse-analytic methodology. Results indicate some variability for participants regarding the meaning of DNR orders, which were nonetheless viewed as appropriate and desirable. ⋯ Non-compliance with DNR orders, or the instigation of CPR was seen as violating nature, infringing autonomy, and as uncompassionate. The combined effect was to construct dying as a natural event which is the concern of the individual patient and their family, endorsing medical non-intervention in the process. This research provides support, from the patients' viewpoint, for a policy of non-intervention when death is imminent and inevitable, and for those questioning the wisdom of a default policy of initiating CPR on any hospitalized patient, especially those patients inevitably in the process of dying.
