Acupuncture’s Role in Solving the Opioid Epidemic: Evidence, Cost-Effectiveness, and Care Availability for Acupuncture as a Primary,

Non-Pharmacologic Method for Pain Relief and

Management – White Paper 2017

Abstract The United States is facing a national opioid epidemic, and medical systems are in need of

non-pharmacologic strategies that can be employed to decrease the public’s opioid depen-

dence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and

available treatment modality suitable to meeting this need. Acupuncture has been shown

to be effective for the management of numerous types of pain conditions, and mechanisms

of action for acupuncture have been described and are understandable from biomedical,

physiologic perspectives. Further, acupuncture’s cost-effectiveness can dramatically

decrease health care expenditures, both from the standpoint of treating acute pain and

through avoiding addiction to opioids that requires costly care, destroys quality of life, and

can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated

that healthcare systems and providers offer non-pharmacologic treatment options for pain.

Acupuncture stands out as the most evidence-based, immediately available choice to fulfill

these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital

settings as diverse as the emergency department, labor and delivery suites, and neonatal

intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is

already being successfully and meaningfully utilized by the Veterans Administration and

various branches of the U.S. military, in some studies demonstrably decreasing the volume

of opioids prescribed when included in care.

of Acupuncturists (ASA), the American Alliance for Professional

Acupuncture Safety (AAPAS), the Acupuncture Now Foundation

(ANF), the American TCM Association (ATCMA), the American TCM

Society (ATCMS), and the National Federation of Chinese TCM

Organizations (NFCTCMO). This article has been simultaneously

1. Introduction

In 2015 it was estimated that 25.3 million Americans suffered

from chronic pain, while an estimated 126 million American

adults reported some type of pain in the prior three months.1 As a

result, more than 240 million prescriptions were written for opioid

medications during that year.2 An unfortunate consequence of

this high use and availability of opioids, is a growing number of

opioid-related deaths from addiction and overdose.

More than 33,000 Americans died from opioid drugs in 2015,

and more than 64,000 died in 2016.3 Due to the severity of this

epidemic, a White House panel urged the United States (U.S.) pres-

ident to declare the opioid crisis a national emergency. August 31,

2017 was designated as “International Overdose Awareness Day”

by the Centers for Disease Control and Prevention (CDC).4

To cope with the opioid crisis, various federal regulatory and over-

sight agencies, including the U.S. Food and Drug Administration

(FDA), the National Academies of Sciences, Engineering, and

Medicine (NASEM), and the Joint Commission have started

to advise or mandate that healthcare systems and providers

offer non-pharmacologic treatment options for pain control.5-7

Acupuncture stands as the most evidence-based, immediately

available choice to fulfil these calls.

The aim of this white paper is to summarize for academic scholars,

healthcare professionals, administrators, policymakers, and the

general public the available evidence for acupuncture as a treat-

ment for various pain conditions as well as for opiate dependency.

This includes evidence on the safety, cost-effectiveness, mecha-

nisms of action, and provider availability for acupuncture.

2. Acupuncture is an effective, safe, and cost-effective treatment for numerous types of acute and chronic pain; acupunc- ture should be recommended as a first line treatment for pain before opiates are prescribed, and may reduce opioid use

2.1 Effectiveness/Efficacy of acupuncture for different types of pain

There is growing research evidence to support the effectiveness

and efficacy of acupuncture for the relief of numerous types of

pain, especially chronic pain, as well as for the use of acupuncture

for a diverse array of medical conditions. In an independently

published work, which is the largest and most comprehensive

of its kind for the period evaluated, McDonald and Janz8 sum-

marized the research from March 2013 to September 2016 for

acupuncture, published and available in all languages on PubMed

and in the Cochrane Library. They looked at systematic reviews,

meta-analyses, network meta-analyses, overviews of systematic

reviews (NHMRC level I evidence), and a number of narrative

reviews. They performed meta-analyses on 62 of the non-Co-

chrane systematic reviews, representing pooled data from more

than 1,000 randomized controlled trials (RCTs). They assessed

and graded the quality of evidence, and noted the strength of

evidence for acupuncture for numerous conditions (Box 1).

Acupuncture has been found to be effective for treating various

types of pain, with the strongest evidence emerging for back pain,

neck pain, shoulder pain, chronic headache, and osteoarthritis. In

an individual patient meta-analysis of 17,922 people from 29 RCTs,

patients receiving acupuncture had less pain, with scores that

were 0.23 (95% confidence interval (CI), 0.13–0.33), 0.16 (95% CI,

0.07–0.25), and 0.15 (95% CI, 0.07–0.24) standard deviations (SDs)

lower than sham controls for back and neck pain, osteoarthritis,

and chronic headache, respectively; the effect sizes in comparison

to non-acupuncture controls were 0.55 (95% CI, 0.51–0.58), 0.57

(95% CI, 0.50–0.64), and 0.42 (95% CI, 0.37–0.46) SDs. A variety

of pain severity and disability scores were used, including Visual

Analog Scale ( VAS) ratings, the Western Ontario and McMaster

Universities Osteoarthritis Index ( WOMAC), and the Roland Morris

Disability Questionnaire. These results were robust to a variety of

sensitivity analyses, including those related to publication bias.9

“ Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives.”

In the largest study of its kind to date, 454,920 patients were

treated with acupuncture for headache, low-back pain, and/or

osteoarthritis in an open pragmatic trial. Effectiveness was rated

by the 8,727 treating physicians as marked or moderate in

76% of cases.10

In a network meta-analysis comparing different physical interven-

tions for pain from knee osteoarthritis, acupuncture was found

to be superior to sham acupuncture, muscle-strengthening

exercise, tai chi, weight loss, standard care, and aerobic exercise

(in ranked order). Acupuncture was found to be more effective

than muscle-strengthening exercises, with a statistically significant

difference = 0.49, 95% CI [0.00–0.98].11

In early 2017, the American College of Physicians (ACP) published

guidelines based on the evidence for the non-invasive treatment

of low-back pain. For acute or subacute low-back pain, the ACP

recommends non-pharmacologic treatment with acupuncture,

along with superficial heat, massage, or spinal manipulation, and

nonsteroidal anti-inflammatory drugs or skeletal muscle relaxants.

For chronic low-back pain, the ACP also recommends acupuncture,

in addition to exercise, multidisciplinary rehabilitation, mindful-

ness-based stress reduction, tai chi, yoga, motor control exercise,

progressive relaxation, electromyography biofeedback, low-level

laser therapy, operant therapy, cognitive behavioral therapy, and

spinal manipulation, etc.12

A systematic review and meta-analysis on acupuncture for the

treatment of sciatica reported that acupuncture was superior to

standard pharmaceutical care (such as ibuprofen, diclofenac, and

prednisone) in reducing pain intensity (mean difference (MD) =

1.25, 95% CI [1.63–0.86]) and pain threshold (MD = 1.08, 95% CI

[0.98–1.17]). Effectiveness, pain intensity, and pain threshold scales

were used.13

A systematic review and network meta-analyses of 21 different inter-

ventions for sciatica found that acupuncture was second in global

effect only to biological agents. It was found to be superior to all

other interventions including non-opioid and opioid medications.14

A systematic review on acupuncture and moxibustion for lateral

elbow pain found moderate-level evidence that acupuncture and

moxibustion were more effective than sham. It also found low-level

evidence that acupuncture and moxibustion may be superior or

equal to standard care.15 A systematic review on acupuncture for

plantar heel pain found that evidence supporting the effectiveness

of acupuncture was comparable to the evidence available for

standard care interventions such as stretching, night splints, and

dexamethasone.16

The use of acupuncture to relieve pain associated with surgical

procedures captured the world’s attention in the early 1970s.

When in China, well-known New York Times journalist James Reston

witnessed acupuncture’s effectiveness on his post-operative pain.

He published his personal experience with acupuncture shortly

before President Richard Nixon’s trip to China.

Since then, reports in the scientific literature reveal that acupunc-

ture has been used before, during, and after surgery to manage pain

and to improve post-surgical recovery in a variety of contexts.17-25 It

is noteworthy to mention that acupuncture has been reported to

be effective in pain relief during and after surgical procedures on

children and animals as well.19,20,26,27

Nonetheless, over the past two decades in the U.S., post-operative

pain management has come to rely increasingly on opioids, while

underutilizing alternative analgesics such as acupuncture. In 2012,

surgeons and dentists combined prescribed 16.2% of all opioids in

the U.S., trailing only family practices as the leading source of opioid

prescriptions at 18.2%.28 Eighty to ninety-four percent of patients

undergoing low-risk surgical procedures fill a prescription for

opioids within seven days.29,30

Recent data has shown that opioid prescriptions vary widely and

that the majority of surgical patients are over-prescribed opi-

oids—approximately 70% of pills go unused.31 The risk of chronic

opioid use after surgery in previously non-dependent patients

is determined to be 5.9%–6.5%,32 although in select populations

such as head and neck cancer patients, the risk is up to 40%.33 The

increase in post-operative opioid use is somewhat paradoxical

considering that known adverse effects such as sedation, pneu-

monia,34,35 ileus, urinary retention, and delirium prolong patient

recovery and delay the meeting of discharge goals.36

Acupuncture has emerged as a promising adjunctive analgesic

modality to reduce the risk of post-operative opioid dependence.

A meta-analysis published in late 2017 in JAMA Surgery focused on

non-pharmacological treatments in reducing pain after total knee

arthroplasty. Thirty-nine RCTs were included in the meta-analysis

(2,391 patients). Moderate-certainty level evidence showed that

electrotherapy reduced the use of opioids (MD = −3.50; 95% CI,

[−5.90 to −1.10] morphine equivalents in milligrams per kilogram

per 48 hours; P = 0.004; I2 = 17%), and that acupuncture delayed

opioid use (MD = 46.17; 95% CI, [20.84–71.50] minutes to the

first patient-controlled analgesia; P < 0.001; I2 = 19%). There was

low-certainty level evidence that acupuncture improved pain

(MD = 1.14; 95% CI, [1.90–0.38] on a VAS at 2 days; P = 0.003; I2 = 0%).

Evidence showed that acupuncture out-performed cryotherapy,

continuous passive motion, and preoperative exercise in the stud-

ied condition.37 Reduction in opioid use has been demonstrated

across a wide range of both minor and major surgical procedures,

including cardiac surgery,38 thoracic surgery,39 and craniotomy.17,40

Additionally, it was reported that acupuncture may even reduce

post-operative ileus and expedite bowel recovery after colorectal

cancer resection.41 Acupuncture is often combined with electric

stimulation, and electro-acupuncture may have added clinical

benefit in post-operative pain management.

A Cochrane systematic review on acupuncture or acupressure

for primary dysmenorrhea found that both acupuncture and

acupressure were more effective in reducing pain than placebo

controls.42 Five other systematic reviews and/or meta-analyses

on various forms of acupoint stimulation including acupuncture,

acupressure, and moxibustion for primary dysmenorrhea have

reported similar outcomes.43-47

The effectiveness of acupuncture for labor pain is still unclear,

largely due to the heterogeneity of designs and methods in

studies, which have produced mixed results. While some studies

reported no reduction in analgesic medications, some studies

reported reduction of pain during labor, reduced use of opioid

medications and epidural analgesia, and a shorter second stage

of labor.48-50

ACUPUNCTURE’S ROLE IN SOLVING THE OPIOID EPIDEMIC – WHITE PAPER 2017

MJAOM | WINTER 2018 17

A systematic review of acupuncture for trigeminal neuralgia

suggests that acupuncture may be equal to or superior to

carbamazepine. However, the evidence is weakened by the low

methodological quality of some included studies.51

A Cochrane systematic review on acupuncture for fibromyalgia

found low-to-moderate certainty level evidence that acupuncture

improves pain and stiffness compared with no treatment and

standard therapy. Furthermore, electro-acupuncture is likely better

than manual acupuncture for pain in fibromyalgia, although more

studies with methodological rigor are warranted.52

A prospective, randomized trial of acupuncture vs. morphine

to treat emergency department/emergency room patients

with acute onset, moderate to severe pain was conducted.

Acupuncture provided more effective and faster analgesia than

morphine and was better tolerated. The study included 300

patients, with 150 patients in each group. Success rate was signifi-

cantly different between the two groups (92% in the acupuncture

group vs. 78% in the morphine group, P < 0.001).

Resolution time was (16 ± 8) minutes in the acupuncture group

vs (28 ± 14) minutes in the morphine group (P < 0.005). Overall, 89

patients (29.6%) experienced minor adverse effects; of these, 85

(56.6%) were in the morphine group and only 4 (2.6%) were in the

acupuncture group (P < 0.001).53

The above-mentioned meta-analysis included 29 trials and 17,922

patients with chronic pain conditions; data on longer-term follow

up (available for 20 trials, including 6,376 patients) suggests

that approximately 90% of the benefit of acupuncture relative

to controls would be sustained at 12 months post-treatment.

Patients can generally be reassured that treatment effects persist

for some duration.54

2.2 Safety and feasibility of acupuncture for pain

management

Strong evidence for the safety of acupuncture in chronic pain

management comes from an open pragmatic trial involving

454,920 patients who were treated for headache, low-back pain,

and/or osteoarthritis. Minor adverse events were reported in 7.9%

of patients while only 0.003% (13 patients) experienced severe

adverse events. Minor adverse events included needling pain,

hematoma, and bleeding, while serious adverse events included

pneumothorax, acute hyper- or hypotensive crisis, erysipelas,

asthma attack, and aggravation of suicidal thoughts.10

In a prospective feasibility study, acupuncture was seen as

feasible, safe, and acceptable in an intensive care unit setting by

patients from diverse backgrounds.55 A systematic review suggests

that acupuncture performed by trained practitioners using clean

needle technique is a generally safe procedure.56 The medical

literature also indicates that acupuncture may be used success-

fully on cancer patients for symptom management due to the low

risks associated with its use.57

2.3 Cost-effectiveness of acupuncture for pain management

A systematic review of eight cost-utility and cost-effectiveness

studies of acupuncture for chronic pain indicated that the cost

per quality-adjusted life-year gained was below the thresholds

used by the UK National Institute for Health and Clinical

Excellence for “willingness to pay.” The chronic pain conditions

discussed in the systematic review included low-back pain, neck

pain, dysmenorrhoea, migraine and headache, and osteoarthritis.58

A cost-effectiveness analysis of non-pharmacological treatments

for osteoarthritis of the knee found acupuncture to be the most

cost-effective option when analysis was limited to high-quality

studies.59 Using acupuncture for pain management, patients and

insurers can save money and successfully manage their pain

and other symptoms without the adverse risks associated with

prescription medications.

A recent study from the Center for Health Information and

Analysis, in response to a piece of Massachusetts legislation

seeking mandated coverage for acupuncture for some conditions,

found that full insurance coverage for acupuncture would

increase an average insured member’s monthly health insurance

premium only by $0.38 to $0.76. Acupuncture was noted to save

$35,480, $32,000, $9 000, and $4,246 per patient for migraine,

angina pectoris, severe osteoarthritis, and carpal tunnel syndrome

respectively.60 Compared to the large fees associated with

imaging, prescription medications and surgery for pain conditions,

acupuncture proved extremely cost-effective.

The Acupuncture Evidence Project also enumerates those

conditions for which they found evidence of acupuncture being

cost-effective (Box 2).61

PERSPECTIVES

Box 2. Conditions with Demonstrated Evidence of Cost-Effectiveness

- Allergic rhinitis

- Low-back pain

- Ambulatory anaesthesia

- Migraine

- Chronic pain: neck pain (plus usual medical care)

- Depression

- Osteoarthritis

- Dysmenorrhoea

- Post-operative nausea and vomiting

- Headache

18 MERIDIANS: The Journal of Acupuncture and Oriental Medicine | WINTER 2018

A 2015 study by Da Silva62 published in the journal Headache

showed acupuncture to be at least as effective as conventional

drug preventative therapy for migraine and to be safe, long-

lasting, and cost-effective. Another 2015 study by Liodden and

Norheim63 noted acupuncture to be potentially useful for post-op-

erative pain and post-operative nausea and vomiting, and to be a

low-cost intervention. A 2014 study by Spackman et al.64 showed

acupuncture to be cost-effective compared to counselling or

usual care alone.

Two studies demonstrated acupuncture’s cost-effectiveness for

the treatment of low-back pain. A study by Taylor et al.65 from

2014 showed that acupuncture as a complement to standard care

for the relief of chronic low-back pain was highly cost-effective,

costing around $48,562 per disability-adjusted life-year (DALY )

avoided. It also found that when comorbid depression was

alleviated at the same rate as pain, the cost was around $18,960

per DALY avoided. A study by Andronis et al.66 also identified

acupuncture as likely to be cost-effective for low-back pain.

2.4 Can adjunctive acupuncture treatment reduce the use

of opioid-like medications?

Some studies have reported reduced consumption of opioid-like

medication (OLM) by more than 60% following surgery when

acupuncture is used.67,68 A pilot RCT also showed a reduction by

39% in OLM use in non-malignant pain after acupuncture, an

effect which lasted fewer than eight weeks after acupuncture

treatment ceased.69 The above mentioned meta-analysis, having

moderate-certainty level evidence, showed that electro-acu-

puncture therapy reduced the use of opioids, and acupuncture

delayed opioid use, with low-certainty level evidence indicating

that acupuncture improved pain.37 The conclusions suggest that

electro-acupuncture may be effective in reducing or delaying the

use of opioid medications.

In a study examining acupuncture’s effectiveness in treating

pain in a military cohort of 172 at a U.S. Air Force medical center,

acupuncture dramatically decreased the use of opiates and

other pain medications among personnel. Opioid prescriptions

decreased by 45%, muscle relaxants by 34%, non-steroidal

anti-inflammatory drugs by 42%, and benzodiazepines by 14%.

Quality of life measures also showed impressive changes, with

some measures of improvements showing statistical significance

(P < 0.001).70

The Veterans Administration is increasingly looking to incorporate

acupuncture into care, as is the U.S. Air Force and other military

branches. Training of military physicians is increasing, and systems

are being studied to further incorporate acupuncture. The military

is rapidly incorporating this care into its offered services for

service members.71,72

Studies of the effects of opioid analgesia in the elderly reveal a

significant burden of disease due to falls from mental impairment.

This is worsened when seniors are using multiple medications

affecting cognition. In a recent study, serious falls as per Medicare

Part A and B ICD/CPT codes were evaluated in 5,556 nursing home

residents aged 65 or greater. Seniors taking > 3+ central nervous

system (CNS) standardized daily doses were more likely to have a

serious fall than those not taking any CNS medications (adjusted

odds ratio = 1.83, 95% CI [1.35–2.48]), and the authors urge,

“Clinicians should be vigilant for opportunities to discontinue or

decrease the doses of individual CNS medications and/or consider

non-pharmacological alternatives.”73

A recent study in the New Zealand Medical Journal noted that

medication-related harms were both common and created a

substantial burden of disease for patients and the healthcare

system. They listed opioids first among the six categories of

medications causing the most significant burden.74 In light of the

findings of these studies and similar, utilization of non-pharmaco-

logic treatment options such as acupuncture must be a priority of

paramount status.

3. Acupuncture’s analgesic mechanisms have been extensively researched and acu- puncture can increase the production and release of endogenous opioids in animals and humans

Mechanisms underlying acupuncture’s analgesic effects have

been extensively researched for over 60 years. In animal models,

acupuncture and/or electro-acupuncture has been shown to

be effective for the alleviation of inflammatory, neuropathic,

cancer-related, and visceral pain. Mechano-transduction of the

needling stimulus at specific points on the body triggers the

release of ATP and adenosine, which bind to local afferents.75,76

Ascending neural pathways involving Aβ, Aδ, and C sensory fibers have been mapped (using techniques such as single fiber

recordings with Evans blue dye extravasation), as have been a

mesolimbic analgesic loop in the brain and brainstem, descending

pathway mechanisms, dopaminergic contributors, and cytokine,

glutamate, nitric oxide, and gamma-amino butyric acid

(GABA) effects.

Acupuncture analgesia has been shown to involve several classes

of opioid neuropeptides including enkephalins, endorphins,

dynorphins, endomorphins, and nociceptin (also known as

orphanin FQ). Among the non-opioid neuropeptides, substance P,

vasoactive intestinal peptide, and calcitonin gene-related peptide

have been investigated for their roles in both the analgesic and

anti-inflammatory effects of acupuncture.77-80

ACUPUNCTURE’S ROLE IN SOLVING THE OPIOID EPIDEMIC – WHITE PAPER 2017

MJAOM | WINTER 2018 19

Given that acupuncture analgesia activates the production and

release of endogenous opioids and activates μ and δ opioid receptors, it is feasible that acupuncture used in conjunction with

OLM might alleviate pain with a lower OLM dose for patients

already taking OLM.81 This idea is further supported by evidence

that acupuncture increases μ opioid receptor binding potential,

allowing for effective analgesia at lower doses of OLM.82

For patients not yet prescribed OLM, acupuncture should be

recommended prior to OLM prescription commencing. This would

be in-line with existing guidelines, such as those by the ACP12 and

the CDC,83 which recommend that safe and effective non-opioid

alternatives should first be exhausted before resorting to OLM.

It is important to note as well that opioids as a monotherapy are

often not as successful as may be thought in the general public

perception. A recent systematic review of opioid analgesics for

low-back pain, which included 7,925 participants, found that

opioids were poorly tolerated and for those who tolerate them

the effect is unlikely to be clinically important within guideline

recommended doses.84

The first ever RCT evaluating the long-term effectiveness of

opioids, found that those on long-term opioid analgesia were

actually in marginally more pain at 12 months than those in the

non-opioid group.85 Hence, complementary methods of pain

control are critical to successful patient management.

4. Acupuncture is effective for the treat- ment of chronic pain involving maladaptive neuroplasticity

Adverse neuroplastic changes can present a challenge in pain

management, as maladaptive neuroplasticity can be associated

with severe chronic pain that is resistant to treatment. Via

peripheral stimulation, acupuncture may relieve the symptoms

of patients affected by problematic neuroplastic changes. There

is evidence that acupuncture has the capacity to reverse adverse

neuroplastic changes in the dorsal horns of the spine, as well as in

the somatosensory cortex.86-89 This suggests that acupuncture may

have an important role in treating chronic pain which involves

adverse neuroplastic changes.

5. Acupuncture is a very promising, already utilized adjunctive therapy in opiate depen- dency and rehabilitation

In 1973, Wen et al.90 from Hong Kong published an accidental

finding that ear acupuncture treatment for respiratory patients

had apparently alleviated opioid withdrawal signs and symptoms.

These findings were replicated by others around the world,

including in New York and Sydney in the mid-1970s.

In 1985, Dr. Michael Smith and colleagues in New York established

the National Acupuncture Detoxification Association (NADA),

which today operates in over 40 countries with an estimated

25,000 providers. There are more than 1,000 programs in the U.S.

and Canada that now use acupuncture to help addicts overcome

their addictions.91

Evidence for acupuncture’s role in addiction treatment has been

found in both animal and human studies. In 2009, Hu et al.92 found

that electro-acupuncture in rats appeared to affect dopamine

neurons in the ventral tegmental area, meaningfully improving

the deleterious effects caused to this area by opioid medication.

In 2012, Lee et al.93 demonstrated that electro-acupuncture could

be used to decrease drug-seeking behaviour in rats. As far back as

1978 it was demonstrated that acupuncture decreased biochem-

ical markers of stress in heroin addicts compared to observational

controls.94

In 2014, Chan et al.95 demonstrated that acupuncture decreased

the amount of morphine used by addicts in treatment and

simultaneously improved sleep in the treatment subjects.

Acupuncture for addiction is a versatile modality that can be

effortlessly integrated into many environments including prisons,

in- and outpatient programs, community centers, disaster relief,

and humanitarian aid efforts. Furthermore, acupuncture addiction

protocols can address acute and prolonged withdrawal symp-

toms, stress and anxiety related to drug withdrawal, and help

prevent relapse. Using drugs to treat those already drug-addicted

is not a rational plan of action, and finding sound, non-pharmaco-

logic treatment options is of paramount importance.

A meta-analysis done in 2012 concluded that “the majority [of

studies] agreed on the efficacy of acupuncture as a strategy for

the treatment of opiate addiction” and that “neurochemical and

behavioral evidence has shown that acupuncture helps reduce

the effects of positive and negative reinforcement involved in

opiate addiction by modulating mesolimbic dopamine neurons.

Moreover, several brain neurotransmitter systems involving

opioids and GABA have been implicated in the modulation of

dopamine release by acupuncture.”96

In a recent RCT involving 28 newborns with neonatal abstinence

syndrome, laser acupuncture plus OLM significantly reduced

the duration of oral morphine therapy when compared to OLM

alone.97 The mechanism for acupuncture in opiate withdrawal

was found to be mediated by the endogenous opioid “dynorphin”

binding to κ opioid receptors.98 While considerable research on acupuncture’s role in addiction is still greatly needed,

long-standing and new data provide a sound foundation for

that future research. Demonstration of trans-species effects with

multiple, plausible mechanisms and documented clinical efficacy

in humans for opioid addiction specifically, coupled with vast,

existing clinical precedent of use in this realm, argues strongly for

acupuncture’s likely value in this domain.

6. Acupuncture has been recommended as a first-line, non-pharmacologic therapy by the FDA as well as the NASEM in coping with the opioid crisis; the Joint Commission has also mandated that hospitals provide non-pharmacologic pain treatment modalities

In early May 2017, the U.S. FDA released proposed changes to its

opioid prescription guidelines. Entitled a “Blueprint for Prescriber

Education for Extended-Release and Long-Acting Opioids,” the

guidelines now recommend that doctors become informed about

non-pharmacologic options for pain control to help avoid the

overuse of opioids.5 Per the FDA’s request, the NASEM released a

report to outline the state of the science regarding prescription

opioid abuse and misuse as well as the evolving role that opioids

play in pain management.

The new NASEM report on pain management and opioids

recommends more public education, reimbursement models, and

support for non-drug approaches to pain treatment. It systemati-

cally summarizes the evidence for acupuncture’s clinical benefits

in treating different pain conditions, and provides an overview of

some of the basic science underlying acupuncture’s mechanisms

in pain management.6

In addition, effective January 1, 2018, the Joint Commission

has mandated that hospitals provide non-pharmacologic pain

treatment modalities.7 Acupuncture is ideally suited to fulfil this

mandate. These official, evidence-based clinical guidelines are in

line with global healthcare trends. As of November 2015, acupunc-

ture had over 870 recommendations in official clinical guidelines

for over 100 conditions from institutions in over 30 countries.99

7. Among the most commonly recommended, non-pharmacological man- agement options for pain relief, evidence supports acupuncture as the most specific and effective for opioid abuse and overuse

Several forms of non-pharmacological management options for

acute and chronic pain have been examined, including physical

therapy, spinal cord manipulation, yoga, tai chi, cognitive behav-

ioral therapy, as well as others. Among those therapies commonly

recommended by medical authorities, evidence supports

acupuncture as the most specific in targeting the endogenous

opioid system. There is more evidence that acupuncture can

induce endorphins to cope with acute and chronic pain in basic

research than for any other non-pharmacological approach for

pain.12,37,53,60 Other mechanisms for acupuncture’s effects have also

been discussed above.

8. Acupuncture is widely available from qualified practitioners nationally

In 2013, more than 28,000 licensed acupuncturists were estimated

to be practicing in the U.S., with many more in training.100 A 2015

study found the number of trained licensed acupuncturist prac-

titioners to be approximately 34,400. This number was noted to

have increased by 23.3% and 52.1% compared to the years 2009

(n = 27 965) and 2004 (n = 22 671) respectively, increasing about

1,266 per year.101 Currently, the Council of Colleges of Acupuncture

and Oriental Medicine has 57 schools in its membership,102 with

approximately ten schools offering doctoral degrees.

The National Certification Council for Acupuncture and Oriental

Medicine has certified more than 18,000 practitioners for minimal

competency.103 The practitioners emerging from this educational

and testing infrastructure are the most highly trained in Chinese

medicine as a complete system, and the training capacity is vastly

underutilized. This system could produce many more practitioners

were demand increased.

The American Academy of Medical Acupuncture also represents

more than 1,300 medical doctors trained to offer acupuncture

services and has approved nine programs for medical doctor

certification in acupuncture.104 One certification program alone

has trained more than 6,000 physicians in medical acupuncture,105

so a conservative estimate of the total number of physicians

trained would be approximately 10,000, though the number

actively practicing acupuncture is unknown.

Most states allow physicians to practice acupuncture, with some

specifying additional training.106 Increased coverage and demand

for acupuncture will lead to a greater supply of providers as well.

As noted above, NADA providers are estimated at 25,000 individu-

als, with more than 1,000 programs in the U.S. and Canada.

There is currently debate within the scientific and academic communities on how to perform high-quality studies on acupuncture. It is widely recognized that standards applied to drug trials are inappropriate for acupuncture studies, as it is impossible to effectively blind patients to treatment with acupuncture as can be done with medications. Hence, this literature review, adhering to standards for drug studies, may undervalue some existing studies, and hence the strength of acupuncture for care may also be underestimated.
