The management algorithm ( FIGURE 2 ) now leads with “core principles”—a term suggesting greater importance than the former term, “general management,” implied. Clinical highlights, a synthesis of key recommendations, have been revised to better align with the guideline’s main components—assessment, functional goals, patient-centered/biopsychosocial care planning, Level I vs Level II approaches, and medication and patient selection.
Other changes in the guideline may contribute to clinicians’ understanding of chronic pain and its complex presentation. The guideline now includes a statement about allodynia and hyperalgesia to indicate that both may play an important role in any pain syndrome—not just complex regional pain syndrome. Information about fibromyalgia symptoms and myofascial pain has been added. The definitions page now has an entry for “biopsychosocial model,” as well as language designed to stress the differences between untreated acute pain and ongoing chronic pain.

A limitation, an improvement
A limitation of the guideline is the lack of studies addressing the effectiveness of a comprehensive, multidisciplinary treatment approach to chronic pain management. Most studies consider single therapies.
An improvement in this guideline is that the evidence levels of each strategy are now listed within the section describing it—a notable change that makes it far easier to identify the quality of individual recommendations.
As has been the case in the past, this latest edition of the guideline offers a number of tools for physicians. The assessment and management algorithms ( FIGURES 1 AND 2 , respectively) walk clinicians through the decision-making process. In addition, the following 9 appendices provide practical guidance to physicians in various aspects of patient evaluation and care:
- Brief Pain Inventory (Short Form)
- Patient Health Questionnaire (PHQ-9)
- Functional Ability Questionnaire
- Personal Care Plan for Chronic Pain
- DIRE (diagnosis, intractability, risk, efficacy) Score: Patient Selection for Chronic Opioid Analgesia
- Opioid Agreement Form
- Opioid Analgesics
- Pharmaceutical Interventions for Neuropathic Pain
- Neuropathic Pain Treatment Diagram.
