Chronic pain is a debilitating condition with a multidimensional impact on the lives of patients, their families and communities. The public health burden of chronic pain is gathering recognition as a major healthcare problem in its own right and deserves closer attention. The challenge in treating chronic pain is to provide effective clinical management of a complex, multifaceted set of conditions that require a coordinated strategy of care. ⋯ I. N. Management is a clinician education program providing up-to-date training in pain management.

Clinical research in interventional pain management techniques: an epidemiologist/trialist's view.
In contrast to drug therapy, interventional pain therapies involve a complex "interaction" between the clinician ("the operator"), the clinical procedure and medical device/equipment. An appreciation of this interaction is fundamental to the understanding of the challenges of designing clinical trials for interventional procedures in chronic pain. This article overviews the evolving evidence requirements of healthcare policy makers and payers, discusses the specific challenges of designing clinical trials of interventional procedures, and outlines some potential clinical trial design solutions to these challenges.

Acute pain is reported as a presenting symptom in over 80% of physician visits. Chronic pain affects an estimated 76.2 million Americans--more than diabetes, heart disease, and cancer combined. It has been estimated to be undertreated in up to 80% of patients in some settings. ⋯ The numeric pain scale certainly has a place in care and in pain management; however, it is important to assess the patient's communication and self-management style and to recognize that patients, like pain, are on a continuum with varied styles of communication and adaptation. It is easy to get lost in the process, even when the process is initiated with the best of intentions. In the quest for individualized medicine, it might be best to keep pain assessment in the individualization arena.

Delirium is an acute fluctuating disturbance in cognitive status, linked to increased morbidity and mortality. The purpose of this pilot study was to assess the feasibility in terms of required time and yield of delirium monitoring by the Acute Pain Service (APS) using the Confusion Assessment Method for Intensive Care Unit instrument. ⋯ The use of this tool required little training, and only 2 minutes per patient. It detected more patients with delirium than did the standard nursing assessments or other patient-clinician interactions. The use of this instrument by the pain service was feasible in terms of time consumption and most likely would be valuable in its yield. Early detection may help in initiating prompt treatment, eliminating known risk factors and thus reducing morbidity.

Informed consent is important: in research, it allows subjects to make an informed and voluntary choice to participate--or refuse to participate--in a project where they will be asked to take risks for the benefit of others. In both research and clinical care, informed consent represents a permission to intervene on a person's private sphere. The elements of informed consent are usually described as disclosure, understanding, decision-making capacity, and voluntariness. ⋯ Moreover, trust is a motivating factor for research participation, and thus we run risks if we allow false expectations and prove ourselves unworthy of this trust. Although improving consent forms does not have a clear effect on understanding, improving the consent process may help. Finally, better information may decrease anxiety and seems to have at most a small negative effect on research recruitment.
