Battlefield Acupuncture for Acute/Subacute Back Pain in the Emergency Department

Study Overview
=================
Brief Summary
-----------------
The randomized controlled study aims was to investigate the pain control of Battle Field Acupuncture as Primary or Adjunctive Treatment in Back Pain (Acute Musculoskeletal pain) in the (acute pain setting) Emergency Department vs stand of care pain medications.

Detailed Description
-----------------
Purpose: To evaluate the effectiveness of Battlefield Acupuncture versus standard care (medicinal therapy) in an Emergency Room setting for acute/subacute back pain using the Visual Analog Scale (VAS) and Numeric Rating Scale (NRS) to determine changes in pain levels. Secondary outcomes will include performance using the back pain functional scale (BPFS), satisfaction of treatment, and the need for further pain medication after discharge from the emergency department. Design and Methods: A prospective, randomized control trial, (un-blinded, non-placebo controlled) with convenience sampling based on scheduled clinical shifts in the Emergency Department. The population consisted of active duty service members and Department of Defense beneficiaries (dependents and retirees) at the DoD's sole Level I trauma center, San Antonio Military Medical Center Emergency Department with acute/subacute, or acute/subacute on chronic back pain as the chief complaint. The participants studied age range was from 18-55 years old without concern for pathological back pain. Subjects were selected based on their chief complaint identified by the triage nurse. A randomized convenience sampling method was used while members of the research team were on shift. Subjects were informed of the study once they were triaged at the Emergency Department treatment area. Members were screened for pathological back pain by history and physical, and if negative were offered enrollment into the study. After informed consent and Health Insurance Portability and Accountability Act (HIPPA), demographics were collected as well as an initial Visual Analog Score (VAS) score, Numeric Rating Scale (NRS) score, and back pain functional scale (BPFS). Participants were randomly assigned to either the treatment or control group based on a random number generator. Subjects then received either BFA or the standard care, which was a pre-determined medicinal treatment. Participants were reassessed at 30-40 minutes post intervention for effectiveness of intervention for both pain and satisfaction. After initial pain control was achieved subjects completed a questionnaire on their perceived effectiveness of BFA as well as if they would repeat BFA in the future. If participants did not feel pain was adequately controlled in the either treatment arm they were provided rescue pain medications based on the preference of the treating provider. At discharge, participants were given further instructions including a follow-up telephone interview between 48-72 hours. In the telephone follow-up, participants were assessed on a Numerical Rating Scale (NRS), repeat functionality questionnaire, and if they used any other pain medications since discharge to help improve their pain (either pain medications given at discharge from the emergency department or their regularly prescribed pain medications). Data Analysis: In this study, the independent variables were treatment for musculoskeletal pain in the emergency department (standard care, battlefield acupuncture) and time (before treatment, 30 to 40 minutes post-treatment and 48 to 72 hours post-treatment). The dependent variable is pain measured on a VAS or NRS at 48-72 hours post-treatment. The null hypothesis is that there is no statistically significant difference in pain related to treatment or time between treatment groups. With 26 subjects per group (52 total), the investigator was able to detect a 1.0 standard deviation (SD) difference measured by a 13mm change in the VAS or a 2 point change in the NRS.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Acupuncture Group<br>Battlefield Acupuncture (BFA) has a structured administration sequence that was utilized to limit any variability between investigators administering the treatment. The BFA technique has been suggested that the needles are placed not just in an acupoint but actually acupoint zones. BFA utilizes one to ten (maximum five points per ear) ASP semi-permanent gold needles® placed in one or both ears. The ASP Gold needle® is a sterile device which inserts a small 2 mm needle into the auricle. It is comprised in single-needle applicator ensuring ease of insertion combined with excellent precision. The needles remain in the ear and fall out spontaneously as early as two hours and up to seven days. After administration of the BFA, if subjects felt that their pain was not controlled based on verbal response, rescue medication could be administered to control pain to a tolerable level for discharge. | Device: Battlefield Acupuncture<br>* 1-10 needles inserted in systematic nature as described by Battlefield acupuncture protocol.<br>|
| Active Comparator: Standard Care Group<br>Participants randomized to the standard care group were treated with one, or a combination of selected medications to include oral Acetaminophen 500mg-1000mg, Diclofenac 50mg-75 mg orally, Diazepam 5mg-10 mg intravenous or oral, Hydrocodone 5mg/325mg-10mg/650mg mg oral, or intramuscular Ketorolac 30mg-60 mg, as deemed appropriate by the treating investigator (medical provider). Standard treatment was administered by the investigators based on the patient's presentation and driving status as many of the medications cannot be administered if the subject would operate a vehicle. No standardized algorithm was specified and the route and dose of medications was administered at the provider's discretion. After administration of the traditional standard care medications, if subjects felt their pain was not controlled based on verbal responses, rescue medication would be given to control pain to a more tolerable level for discharge. | Drug: Acetaminophen<br>* Acetaminophen 500mg-1000mg,<br>* Other names: Tylenol;Drug: Diclofenac<br>* Diclofenac 50mg-75 mg orally<br>* Other names: Voltaren;Drug: Diazepam<br>* Diazepam 5mg-10 mg intravenous or oral<br>* Other names: Valium;Drug: Hydrocodone<br>* Hydrocodone 5mg/325mg-10mg/650mg mg<br>* Other names: Norco;Drug: Ketorolac<br>* oral, or intramuscular Ketorolac 30mg-60 mg<br>* Other names: Toradol;|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| time-response of BFA, and the association with pain level using the Visual Analog scale (0-10 mm) scoring as well as the Numeric Rating Scale (0-10) scoring | determine if there is any significant change in pain in the BFA treatment group at specific time points using the Visual Analog scale (0-10 mm) scoring as well as the Numeric Rating Scale (0-10) scoring | before treatment, 30-40 minutes post-treatment, and 48 to 72 hours post-treatment | 
| Evaluate the change of pain on Visual Analog scale (0-10mm) scoring with BFA administered in the emergency department for persons presenting with non-pathologic back pain. | Using the Visual Analog scale which is a 10mm line, the patient will place a mark on the graph which will be measured to determine if there is any significant difference between the BFA treatment group pain at specific timepoints using the VAS. The lower the score determined on the scale corresponds to a lower pain level for the patient and a higher score corresponds to a higher pain level. | baseline and at 30-40 minutes post treatment | 
| Evaluate the change of pain on Numeric Rating Scale (0-10) scoring with BFA administered in the emergency department for persons presenting with non-pathologic back pain. | The Numeric Rating scale which is a scale that is verbally asked to determine the patients pain response on a scale from 0 to 10 determine if there is any significant difference between the BFA treatment group pain at specific timepoints using the NRS. The lower the score determined on the scale corresponds to a lower pain level for the patient and a higher score corresponds to a higher pain level. | baseline, 30-40 minutes, and 48-72 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
