Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1
Ten ASP (Aigulle Acupuncture semi-Permanent) gold needles inserted according to the Battlefield ear acupuncture protocol (5 needles each ear i.e. cingulate gyrus, thalamus, omega, point zero and Shenmen), needles concealed with 10 DuoDerm tapes and then also receive standard analgesia care (see below). Acupuncture practitioners will be usual health care providers i.e. non-acupuncturists (emergency doctors, nurse practitioners, registered nurses) trained by the principal investigator (a registered medical acupuncturist).
Reference Battlefield ear acupuncture protocol: Niemtzow RC. Battlefield acupuncture. Medical Acupuncture. 2007 Dec 1;19(4):225-8.
Note: Duoderm tapes are cut into approximately 1cm squares with a central mark to obscure needle. Product information on extra thin Duoderm dressings can be obtained from: https://www.convatec.com.au/advanced-wound-care/duoderm-dressings/duoderm-extra-thin-dressing/

Arm 2
The second arm or sham group will have a piezoelectric device (Pulsar Plus Piezo Stimulator) sounded adjacent (1-2cm) to but not onto the ear. Normally the piezo stimulator generates a single electric impulse by compressing and releasing pressure on a piezo crystal inside the stimulator. However, because it is only activated in the air away from the patient, no electric current enters the patient and the only perceived intervention is a clicking sound - hence used as our sham device. 10 DuoDerm tapes will be applied similarly to the needle intervention arm and then will also receive standard analgesia care (see below). Product information on the Pulsar Plus Piezo Stimulator can be obtained from: https://www.heliosupply.com.au/index.php/electro-laser/stimulators-point-locators/electrical-leads-wq001-2.html

Arm 3
The third arm is the standard analgesia care group alone. This group will have standard analgesia care and 10 DuoDerm tapes also applied. Standard usual analgesic care consists of:
Patients with a NPRS-10 greater or equal to 4 and less than or equal to 7 will receive paracetamol 1g orally / intravenously and Ibuprofen 400-800mg orally or Ketorolac 10mg intravenously / 15mg intramuscularly pending last dose of relevant / same analgesic.
Rescue medication is oral / under the tongue opioid after 30 minutes’ post triage: Oxycodone 5-10mg orally, Buprenorphine 200-400mcg under the tongue or Tapentadol IR 50 – 100mg orally. Antiemetic if nauseated

Patients with a NPRS-10 > 7 will receive above regime for paracetamol / non-steroidal anti-inflammatory and rapid acting opioid: Fentanyl 1.5mcg/Kg/dose intranasally – max 2 doses or intravenously, Fentanyl 25mcg boluses to 100mcg total intravenously or Morphine 1-2.5mg boluses to 10mg total intravenously. Further rescue doses of Fentanyl intravenously, Morphine intravenously and Oxycodone 5-10mg orally. Antiemetic if nauseated

The expected duration of application of the ear needles per patient is approximately 4 minutes. This application time is a secondary outcome. Needles will remain in situ for 2 hours and then removed.

Total oral morphine equivalent opioid dose (milligrams) in 2 hours from intervention.
Total opioids administered within the 2-hour frame from intervention obtained retrospectively (post attendance) from the patient's drug chart (hospital record) and will be calculated by converting the dosage of the various administered opioids in that 2 hour time frame to a oral morphine dose (milligrams) equivalent. The Faculty of Pain Medicine ANZCA opioid dose converter which is an evidence-based and authoritative opioid conversion application will be used i.e. http://www.opioidcalculator.com.au/

2 hours post-intervention
Secondary outcome [5] 350498 0
Adverse effects using a spontaneous (unsolicited) reporting method will be collected using a non-structured open-ended question for either intervention (acupuncture or sham) or pharmacological analgesia.

Costings: Will include prices (AUD) of analgesics and needles used. Analgesics used during the 2-hour time period will be obtained from the medical record and prices calculated from analgesia imprest costs provided by the private pharmacy supplier for the ED.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation will be allocated prior to the trial with opaque sealed envelopes placed in a draw on site and opened post consent to enter the trial. The envelopes will be marked: low back pain 1-30, abdominal pain 1-30 and limb trauma pain 1-30.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Ninety patients (30 from each pain condition) will be randomly allocated to one of the three treatment arms, such that each treatment arm comprises 10 patients from each pain condition, using a block size of six. The randomisation sequence will be determined using Stata (15.0 StataCorp™, College Station, TX, USA) by a statistician not involved in treatment allocation or data collection. Patients will only be invited to participate into the trial when a trained investigator is available.

Efficacy
Statistical methods / analysis
Data analysis will consist of using the independent Student’s t-test for continuous data and Chi-square for categorical data using the Stata software program. The continuous variables include: NPRS-10, morphine dose equivalent (mg).

Categorical variables will be used to compare the differences in proportions for demographics of the three treatment arms including sex, medical condition and age group. Non-parametric tests such as the Kruskall Wallis will be used to confirm results from the t test in case there is a violation of the normality assumption. Generalised Linear mixed models will be used to analyse NPRS-10s controlling for confounding variables such as time. Both parametric and non-parametric analysis will be performed on the satisfaction scores (six-point Likert scale). Costing will include prices of consumables and medications. Needling time will be compared to an approximated time taken for administration of opioids approximated from a prior audit. Data analysis will be blinded and using ‘intention to treat’ to avoid bias from any dropouts.
