Acupuncture Approaches for Chronic Pain

Study Overview
=================
Brief Summary
-----------------
Chronic pain is a major public health problem that places many burdens on individuals, including impairment of physical and psychological functioning, lost productivity, and side effects of medications used to treat pain. There is also substantial evidence that minority populations differ both in prevalence and outcomes of chronic pain; access to care is a key component in these differences. Strong evidence now supports the use of acupuncture in the treatment of chronic pain conditions, including when provided in the primary care setting to participants from ethnically diverse, medically underserved populations. Acupuncture is slowly being integrated into pain management in many conventional health care settings, but cost and reimbursement for this service remain obstacles to offering acupuncture, especially in primary care and safety net settings. Because group acupuncture can be offered at much lower cost, demonstrating that individual and group delivery are equally effective could reduce barriers to use of this effective pain management approach. The primary aim of this study will be to evaluate whether acupuncture delivered in the group setting for participants with chronic pain is equal to acupuncture delivered in the individual setting. A secondary objective will be to use qualitative analysis to understand and describe the participants' experience of both acupuncture approaches, and to utilize this data to inform intervention delivery and dissemination, to better incorporate the participants' perspective.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain Interference as Measured by the Brief Pain Inventory (BPI) (Intent to Treat Model) | The Brief Pain Inventory (BPI) short form, is a self-reported questionnaire that serves as the primary measure of how much the participants' pain interferes with daily life. Pain interference is calculated using 7 questions that range from a score of 0 (no pain) to 10 (worst pain imaginable). The scores are added and divided by 7, therefore final scores can range from 0 - 10. Having a higher mean score indicates your pain severity is worse. Investigators measured improvement in BPI pain interference from baseline to week 24 (12 weeks after treatment window). The definition of intent to treat is all participants who were randomized into treatment. Statistical analysis only performed on baseline and week 12 (end of treatment) data. | Baseline, Week 12 (end of treatment window), and Week 24 (12 Weeks After Treatment Window) |

Only participants who report having an opioid prescription are included in the analysis therefore if the participant did not have an opioid prescription they were excluded from the analysis. Statistical analysis only performed on baseline and week 12 (end of treatment) data. | Baseline, Week 12 (end of treatment window), and Week 24 (12 Weeks After Treatment Window) | 
| Number of Days Participants Reported Using Prescription Opioids in the Last 7 Days (Intent to Treat Model) | Participants were asked whether they took any opioid medication within the last week. If they did take any opioids in the last week we asked how many days they took their opioid medication. We collected data on the mean number of days participants took prescription opioid medication from baseline to week 24 (12 weeks after treatment window). The definition of intent to treat is all participants who were randomized into treatment. Statistical analysis only performed on baseline and week 12 (end of treatment) data. | Baseline, Week 12 (end of treatment window), and Week 24 (12 Weeks After Treatment Window) | 
| Number of Days Participants Reported Using Prescription Opioids in the Last 7 Days (Per Protocol Model) | Participants were asked whether they took any opioid medication within the last week. If they did take any opioids in the last week we asked how many days they took their opioid medication. We collected data on the mean number of days participants took prescription opioid medication from baseline to week 24 (12 weeks after treatment window). The definition of Per Protocol is all participants who were randomized and who attended >=8 sessions of acupuncture. Statistical analysis only performed on baseline and week 12 (end of treatment) data. | Baseline, Week 12 (end of treatment window), and Week 24 (12 Weeks After Treatment Window) | 
| Change in Participant Opioid Use in Milligrams of Morphine Equivalents (MME) Between 3 Months Pre and 3 Months Post-treatment Using Electronic Medical Record (EMR) Data (Intent to Treat Model) | Milligrams of Morphine Equivalence (MME) is a value assigned to represent how strong an opioid is. It is determined by calculating a dose of morphine equivalent to the prescribed opioid. We compared the MME for participants who had Opioid prescriptions in their electronic medical records (EMR) during the 6 month period around treatment (3 months prior and post-treatment). A smaller MME indicates that the participant was using less medication. The definition of intent to treat is all participants who were randomized into treatment. The analysis is limited to participants who have documented opioid prescriptions in EMR. The change in MME was defined as post treatment minus pre treatment (in milligrams). | 6-Month Period Around Treatment Window (3 months pre- and 3 months post-treatment) |

| Participants With Opioid Prescription Within a 6 Month Period Around Treatment Window According to Electronic Medical Record (EMR) Data (Intent to Treat Model) | Participants' electronic medical records (EMR) were reviewed to see if they had a prescription for opioids during the 6-month period around their treatment window (3 months pre- and 3 months post-treatment). The definition of intent to treat is all participants who were randomized into treatment. There were 191 total participants that had any documented opioid prescriptions in EMR. | 6-Month Period Around Treatment Window (3 months pre- and 3 months post-treatment) | 
| Participants With Opioid Prescription Within a 6 Month Period Around Treatment Window According to Electronic Medical Record (EMR) Data ) (Per Protocol Model) | Participants' electronic medical records (EMR) were reviewed to see if they had a prescription for opioids during the 6-month period around their treatment window (3 months pre- and 3 month post-treatment). The definition of Per Protocol is all participants who were randomized and who attended >=8 sessions of acupuncture. | 6-Month Period Around Treatment Window (3 months pre- and 3 months post-treatment) |
