THE NEED FOR MULTIDIMENSIONAL CHRONIC PAIN ASSESSMENT
Chronic pain is common, complex, costly, and distressing to patients, families, and clinicians. Despite multiple national initiatives,1,2 improvements in chronic pain management have been limited. In fact, an estimated 40–60% of patients with chronic pain have inadequate pain management.3 This lack of progress may partly be due to the multidimensionality of chronic pain, which is not routinely incorporated into its assessment and management. A patient-centered approach—that accounts for patient-specific goals and patient-reported outcomes and can be implemented in a congested, time-limited primary care clinic setting—is needed to achieve the primary goals of chronic pain management, including reduction of pain impact and improvement of function and quality of life.3,4
A QUESTION UNASKED IS AN ANSWER UNLEARNED: USE OF A PATIENT-REPORTED OUTCOMES TOOL TO PROVIDE MULTI-MODAL CHRONIC PAIN CARE
To facilitate individually tailored, comprehensive chronic pain care and patient engagement in pain management, clinicians and informaticists at the University of Washington (UW) Center for Pain Relief developed an online patient-reported outcome measurement tool, called PainTracker™. New patients seeking care at UW’s Center for Pain Relief receive unique login information to complete the online PainTracker assessment prior to their clinic appointment, and data are accessed by clinic intake staff through the PainTracker provider portal. As described in Table 1, intake assessments include questions about treatment history, treatment goals and expectations, as well as pain (e.g., pain intensity, interference, pain-related disability, problems with pain medications) and non-pain (e.g., anxiety, depression, health-related quality of life) domain questionnaires. In addition, a body diagram and supplemental questionnaires aid in the diagnosis of specific pain conditions (e.g., radiculopathy versus widespread pain that may indicate fibromyalgia). Providers are alerted when patients’ risk or symptom severity scores exceed established threshold values (see Fig. 1), and so support clinical decisions addressing key patient psychosocial problem areas (e.g., referral to behavioral health, sleep specialists).
Prior to each follow-up appointment, patients complete a subset of core outcome questions (see Table 1). PainTracker displays longitudinal data graphically for providers and patients to quickly visualize areas of improvement or continued difficulty and tailor treatment accordingly. This systematic multidimensional assessment allows for the delivery of dynamic, individualized pain management and accurate evaluation of response to treatment(s). Review of PainTracker graphs with patients allows providers to demonstrate that improvement in sleep, function, and mood often occurs before improvement in pain (see Fig. 1). Identification of treatment goals and expectations is a critical component of PainTracker that engages patients as active participants in their care, facilitates patient-provider communication, promotes individually tailored benchmarks for improvement, and ensures realistic treatment expectations.
An evaluation of aggregate PainTracker data illustrates the necessity for multidimensional pain assessment. A substantial proportion of more than 4000 adult patients exceeded clinically meaningful threshold values for depression (57.4%), anxiety (33.3%), and post-traumatic stress disorder (27.7%). Most patients were severely disabled or worse (64.7%) and many were identified as moderate-high risk for opioid misuse (40.1%) and high risk for obstructive sleep apnea (56.7%) (unpublished data). Knowledge of these problem areas can save patients and providers valuable time and frustration from disappointing treatment failures.
ROLE OF PRIMARY CARE
Primary care physicians play an integral role in the successful coordination of chronic pain care and the implementation of standardized, multidimensional assessment is necessary for the provision of effective multi-modal patient-centered care. Such measurement is essential for establishing clinical practice guidelines for coordinated inter-specialty care of patients with chronic pain, such as measurement-based “step care.”5 Importantly, a sample of primary care providers (N = 30) found an early version of PainTracker easy to use (70%) and believed it helped patients to participate in their pain management (77%),6 providing evidence of the acceptability, feasibility, and utility of incorporating measurement-based chronic pain care into the primary care setting. While PainTracker is not currently available outside the University of Washington system, the instruments included are freely available and can be adopted for use in the primary care setting. A paper version can suffice as an early adoption strategy.
The systematic evaluation of patient-reported outcomes spanning pain and non-pain domains is necessary for capturing the multidimensionality of the pain experience, useful for guiding treatment decisions, and enhances patient engagement in their own pain care.
