AAFP Chronic Pain Toolkit PAIN ASSESSMENT | Section 1 OVERVIEW Assessment of chronic pain should be multidimensional. Consideration should be given to several domains, including the physiological features of pain and its contributing factors, with physicians and other clinicians assessing patients for function, quality of life, mental health, and emotional health. In addition to a complete medical and medication history typically obtained at an office visit, documentation should be obtained about pain intensity, location, duration, and factors that aggravate or alleviate pain. A physical exam should include musculoskeletal and neurological components, as appropriate. Diagnostic testing and imaging may also be considered for some types of chronic pain. Many organizations, including the AAFP, recommend against imaging for low back pain within the first six weeks of treatment unless there are reasons for the imaging. These reasons may include concerns of underlying conditions, such as severe or progressive neurological deficits, or if osteomyelitis is suspected.1 Periodic reassessments of chronic pain and treatment should focus on evaluating improvements in physical health; mental and emotional health; progress towards functional treatment goals; and effectiveness and tolerability of medications for chronic pain treatment. Currently, there are no universally adopted guidelines or recommendations for assessment of chronic pain. The use of appropriate assessment tools can assist in diagnostic assessment, management, reassessment, and monitoring of treatment effects. Multiple tools are available, with many embedded in electronic health record (EHR) systems. Pain Assessment Tools The table on the next page includes selected tools for pain assessment included in this toolkit, along with links and reference to additional tools. Assessments about other relevant domains are covered in Functional and Other Assessments (Section 2). 2 AMERICAN ACADEMY OF FAMILY PHYSICIANS AAFP Chronic Pain Toolkit Pain Assessment Tools in Toolkit Name Use Scoring Description Location Brief Pain Assess pain severity • Worst pain score: 1-4 = mild pain Fillable PDF completed in Jump to tool in toolkit.
