Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Acupuncture Group

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.

Intervention Type DEVICE

1-10 needles inserted in systematic nature as described by Battlefield acupuncture protocol.

Standard Care Group

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.
