Content validity of patient-reported outcome measures for patients with chronic pain: considering the patient's perspective

ABSTRACT

Understanding chronic pain and disability requires a consideration of the lived experience of the patient. There is limited evaluation of the content validity of patient-reported outcome measures (PROMs) in chronic pain using a comprehensive biopsychosocial view of the patient's experience. To address this gap, this study aimed to evaluate the content validity of PROMs for patients with chronic pain. A literature review was performed to identify PROMs for patients with chronic pain. Concepts from PROMs were linked to the International Classification of Functioning, Disability, and Health (ICF); the ICF Core Set for Chronic Widespread Pain; and the International Classification of Diseases-11 Functioning Properties of Chronic Pain (FP). Concepts were compared with published "attributes'' of chronic pain. 62 PROMs (1336 items total) were identified and linked to 560 unique second-level ICF categories. The greatest number of items across PROMs were represented in the activities and participation category (44% of all total items), followed by body functions (41%), environmental factors (9%), personal factors (5%), and body structures (0.3%). There was a 41% to 78% match with the Core Set for Chronic Widespread Pain and the International Classification of Diseases-11 FP, respectively. 20% of items reflected the pain-experience attributes with the most items reflecting the concept of "control over pain." Content validity analysis suggests chronic widespread pain patient-reported outcome measures poorly address attributes of living with chronic pain that matter most to patients. Future development or refinement should consider a more comprehensive view of the patients' lived experience.

Development and field testing of primary care screening tools for harms of long-term opioid therapy continuation and tapering to discontinuation: a study protocol

INTRODUCTION

Despite calls for screening tools to help providers monitor long-term opioid therapy (LTOT) harms, and identify patients likely to experience harms of discontinuation, such screening tools do not yet exist. Current assessment tools are infeasible to use routinely in primary care and focus mainly on behaviours suggestive of opioid use disorder to the exclusion of other potential harms. This paper describes a study protocol to develop two screening tools that comprise one integrated instrument, Screen to Evaluate and Treat (SET). SET1 will indicate if LTOT may be harmful to continue (yes or no), and SET2 will indicate if tapering to discontinue opioids may be harmful to initiate (yes or no). Patients receiving LTOT who screen positive on the SET tools should receive subsequent additional assessment. SET will give providers methods that are feasible to implement routinely to facilitate more intensive and comprehensive monitoring of patients on LTOT and decision-making about discontinuation.

METHODS AND ANALYSIS

We will develop the screening tools, SET1 and SET2, concurrently. Tool development will be done in stages: (1) comprehensive literature searches to yield an initial item pool for domains covered by each screening tool; (2) qualitative item analyses using interviews, expert review and cognitive interviewing, with subsequent item revision, to yield draft versions of each tool; and (3) field testing of the draft screening tools to assess internal consistency, test-retest reliability and convergent and discriminant validity.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Institutional Review Boards of Stanford University and the University of California, San Francisco for the VA Palo Alto Health Care System, and the VA San Francisco Healthcare System, respectively. Findings will be disseminated through peer-reviewed manuscripts and presentations at research conferences.

Correlates of Manual Therapy and Acupuncture Use Among Rural Patients Seeking Conventional Pain Management: A Cross-sectional Study

OBJECTIVE

In this cross-sectional study, we examined correlates of manual therapy (spinal manipulation, massage therapy) and/or acupuncture use in a population engaging in conventional pain care in West Virginia.

METHODS

Participants were patients (aged 18+ years) from 4 Appalachian pain and rheumatology clinics. Of those eligible (N = 343), 88% completed an anonymous survey including questions regarding health history, pain distress (Short Form Global Pain Scale), prescription medications, and current use of complementary health approaches for pain management. We used age-adjusted logistic regression to assess the relation of sociodemographic, lifestyle, and health-related factors to use of manual therapies and/or acupuncture for pain (complete-case N = 253).

RESULTS

The majority of participants were white (92%), female (56%), and middle aged (mean age, 54.8 ± 13.4 years). Nearly all reported current chronic pain (94%), and 56% reported ≥5 comorbidities (mean, 5.6 ± 3.1). Manual therapy and/or acupuncture was used by 26% of participants for pain management (n = 66). Current or prior opioid use was reported by 37% of those using manual therapies. Manual therapy and/or acupuncture use was significantly elevated in those using other complementary health approaches (adjusted odds ratio, 3.0; 95% confidence interval, 1.5-5.8). Overall Short Form Global Pain Scale scores were not significantly associated with use of manual therapies and/or acupuncture after adjustment (adjusted odds ratio per 1-point increase, 1.01; 95% confidence interval, 1.00-1.03).

CONCLUSION

We found no evidence for an association of pain-related distress and use of manual therapies and/or acupuncture, but identified a strong association with use of dietary supplements and mind-body therapies. Larger studies are needed to further examine these connections in the context of clinical outcomes and cost-effectiveness in rural adults given their high pain burden and unique challenges in access to care.
