The first step in treating pain effectively is properly assessing it. A number of tools and protocols are available to clinicians to guide them in pain assessment, including scales for pain rating and guidelines for special populations.
Health professionals should always remember that the patient's own report of pain is indispensable in assessing and treating it. Objective tests and data often correlate poorly with the level of pain experienced, and the key diagnostic tool of simply listening to patients should be fully utilized.
It is just as important that initial assessments be followed by regular reassessments in order to gauge the efficacy of treatment and emerging needs. Reassessment is appropriate upon each new report of pain from the patient and soon after a treatment intervention.
