Quality assurance and assessment in pain management.

Relief from pain is itself a marker of high-quality medical care. Quality assurance in the case of pain management could simply mean successful elimination of pain. Because the means of controlling pain are imperfect, it is essential to consider whether pain interventions actually achieve the primary goal of pain relief and also whether they are safe, cost-effective, and even capable of producing secondary benefits such as early recovery from surgery. Quality assurance and assessment in pain management therefore becomes a complex undertaking that must incorporate into its processes the often-conflicting goals of comfort versus safety versus patients' rights.
