Principles of Pain Assessment

• Pain should be assessed in all patients (JCAHO Standard PE 1.4, 2000)

• Patient’s self-report is the single most reliable indicator of pain absent of objective report

• Physiological and behavioral signs of pain (tachycardia, grimacing, etc. ) are neither sensitive nor specific for pain

• Uniform threshold of pain does not exist because pain tolerances vary among individuals

• Unrelieved pain causes adverse health effects both physically and psychologically

• Assessment should address physical and psychological aspects of pain
