Exploring the Role of Chronic Pain Clinics: Potential for Opioid Reduction

Background: The management of chronic nonmalignant pain with high-dose opioids has partially contributed to the current opioid epidemic, with some responsibility shared by chronic pain clinics. Traditionally, both primary care providers and patients used chronic pain clinics as a source for continued medical management of patients on high-dose opioids, often resulting in tolerance and escalating doses. Although opioids continue to be an important component of the management of some chronic pain conditions, improvement in function and comfort must be documented. Pain clinics are ideally suited for reducing opioid usage while improving pain and function with the use of a multimodal approach to pain management. We assessed whether the application of multimodal treatment directed by pain specialists in a pain clinic provides for improved function and reduced dosages of opioid analgesics. Objective: We evaluated the role of a pain clinic staffed by fellowship-trained pain physicians in reducing pain and opioid use in chronic nonmalignant pain patients. Study Design: This study used a retrospective design. Setting: The research took place in an outpatient pain clinic in a tertiary referral center/teaching hospital. Methods: Of 1268 charts reviewed, 296 patients were on chronic opioids at the time of first evaluation. After a thorough evaluation, the patients were treated with nonopioid pharmacotherapy and interventional pain procedures as necessary. The data utilized from patients’ latest follow-up visit included current pain level using the Numerical Rating Scale (NRS-11), opioid usage, and various functional parameters. Results: NRS-11 scores decreased by 33.8% from 6.8 (± 0.1)/10 to 4.5 (± 0.2)/10. The pain frequency and number of pain episodes improved by 36.8 ± 2 and 36.2 ± 2.1, respectively. Additionally, the ability to sleep, work, and perform chores significantly improved. Total opioid use decreased by about 55.4% from 53.8 ± 4 to about 24 ± 2.8 MME/patient/day. Limitation: This study is not a randomized prospective controlled study. The patients analyzed are still getting therapy and their pain status may change. Some opioids are underrepresented in the analyzed cohort. Finally, this study lacks in-depth stratification by type of pain, age, gender, and duration of opioid use. Conclusion: Chronic pain clinics can play a pivotal role in reducing opioid usage while improving pain and function in patients on chronic opioids. We wish to emphasize the importance of allocating resources toward nonopioid treatments that may improve the function and well-being of patients.

Relationship Between Opioid Analgesic Prescription and Unemployment in Patients Seeking Acupuncture for Chronic Pain in Urban Primary Care

Objective The widespread use of opioid analgesics to treat chronic nonmalignant pain has contributed to the ongoing epidemic of opioid-related morbidity and mortality. Previous studies have also demonstrated a relationship between opioid analgesic use and unemployment due to disability. These studies have been limited to mainly white European and North American populations. The objective of this study is to explore the relationship between opioid analgesic use for chronic nonmalignant pain in an urban, mainly black and Hispanic, low-income population. Design This is a cross-sectional observational study. Setting Subjects were recruited from six urban primary care health centers. Subjects Adults with chronic neck, back, or osteoarthritis pain participating in an acupuncture trial were included. Methods Survey data were collected as a part of the Acupuncture Approaches to Decrease Disparities in Pain Treatment two-arm (AADDOPT-2) comparative effectiveness trial. Participants completed a baseline survey including employment status, opioid analgesic use, the Brief Pain Inventory, the global Patient Reported Outcomes Measurement Information Systems quality of life measure, the Patient Health Questionnaire-9 (PHQ-9), and demographic information. A multivariable logistic regression model was built to examine the association between opioid analgesic use and unemployment. Results Opioid analgesic use was associated with three times the odds of unemployment due to disability while controlling for potential confounders, including depression, pain severity, pain interference, global physical and mental functioning, and demographic characteristics. Conclusions This study adds to the growing body of evidence that opioid analgesics should be used with caution in chronic nonmalignant pain.
