Chronic Pain

ADS

Pain is whatever the experiencing person says it is, existing whenever the person says it does (McCaffery, 1968); an unpleasant sensory and emotional experience arising from actual or potential tissue damage or described in terms of such damage; sudden or slow onset of any intensity from mild to severe, constant or recurring, without an anticipated or predictable end and a duration >6 months (NANDA); a state in which an individual experiences pain that persists for a month beyond the usual course of an acute illness or a reasonable duration for an injury to heal, is associated with a chronic pathologic process, or recurs at intervals for months or years (Bonica, 1990)

Defining Characteristics:

Subjective
Pain is always subjective and cannot be proved or disproved. The client's report of pain is the most reliable indicator of pain (Acute Pain Management Guideline Panel, 1992). Clients with cognitive abilities who can speak or point should use a pain rating scale (e.g., 0 to 10) to identify their current level of pain intensity (self-report) and determine a comfort/function goal (McCaffery, Pasero, 1999).

Objective
Expressions of pain are extremely variable and cannot be used in lieu of self-report. Neither behavior nor vital signs can substitute for the client's self-report (McCaffery, Ferrell, 1991, 1992; McCaffery, Pasero, 1999). However, observable responses to pain are helpful in its assessment, especially in clients who cannot or will not use a self-report pain rating scale. Observable responses may be loss of appetite or the inability to ambulate, perform activities of daily living (ADLs), work, or sleep. Clients may show guarding, self-protective behavior, self-focusing or narrowed focus, distraction behavior ranging from crying to laughing, and muscle tension or rigidity. In sudden severe pain, autonomic responses such as diaphoresis, blood pressure and pulse changes, pupillary dilation, and increase or decrease in respiratory rate and depth may be present but are usually not present with chronic pain that is relatively stable. Clients with chronic, cancer, or nonmalignant pain may experience threats to self-image; a perceived lack of options for coping; and worsening helplessness, anxiety, and depression. Chronic pain may affect almost every aspect of the client's daily life, including concentration, work, and relationships.


Related Factors:
Actual or potential tissue damage; tumor progression and related pathology; diagnostic and therapeutic procedures; nerve injury (neuropathic pain)
NOTE: The cause of chronic nonmalignant pain may not be known because pain is a new science and an area of diverse types of problems.

  • Demonstrates ability to pace self, taking rest breaks before they are needed
