Abstract

A great deal has been learned in the past fifteen years from the study of pain mechanisms. More recently, the relief of pain has begun to receive much needed attention as well. Although most, if not all, acute and cancer pain can be relieved, recent evidence shows that inadequate treatment of pain is still common among the general population—even for pain due to cancer. Inadequate treatment of cancer pain is even more likely if the patient is a member of an ethnic minority, female, elderly, or a child. Evidence also suggests that substance abusers are at risk for poor pain treatment.A number of barriers which involve problems of knowledge, attitudes, and laws and regulations affect health care professionals, patients, and the health care system; collectively, they contribute to the inadequate treatment of pain.
