Changing the pain-management paradigm from opioids to organic interventions

Updated: May 1

There is no denying that mechanical and neurological pain has been one of the biggest burdens on productivity in the workplace and homestead. Surprisingly, pain effects more people than cancer, heart disease, and diabetes combined.1 25.3 million American adults suffer from pain on a daily basis.2 2/3 of office workers have experienced pain in the last 6 months and 1/4 of them believe it’s a normal part of the job.3 As a result, the pain is commonly untreated and the worker joins the other 100 million Americans suffering from chronic pain.3 The total costs attributable to low back pain alone in the United States were estimated at $100 billion in 2006, 2/3 of which were indirect costs of lost wages and productivity in the workplace.4

Initially, as most patients with acute/subacute low back pain improve over time regardless of treatment, the American College of Physicians (ACP, 2017) recommends that clinicians and patients should select nonpharmacologic treatment with superficial heat, massage, acupuncture, or spinal manipulation. If pharmacologic treatment is desired, clinicians and patients should select nonsteroidal anti-inflammatory drugs or skeletal muscle relaxants.4

Each of these suggested nonpharmacologic treatments in the acute/subacute phase can be implemented by an Osteopractic Physical Therapist. Moist hot packs are a standard in every Physical Therapy clinic. Massage can be performed in a variety of deep/soft tissue mobilization techniques such as Instrument-Assisted Soft Tissue Mobilization, body tempering, and static and dynamic cupping. Additionally, Osteopractors are certified in Functional Dry Needling/Electro Dry Needling, a scientific/western medicine version of acupuncture.5 Lastly, an Osteopractor is certified in Spinal Manipulation Therapy.5

For patients with chronic low back pain, the ACP strongly recommends that clinicians and patients should initially select nonpharmacologic treatment with exercise, multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction, tai chi, yoga, motor control exercise, progressive relaxation, electromyography biofeedback, low-level laser therapy, operant therapy, cognitive behavioral therapy, or spinal manipulation.4

If the patient response to these interventions is insufficient, it would then be appropriate for clinicians and patients to consider pharmacologic treatment with nonsteroidal anti-inflammatory drugs, followed by tramadol or duloxetine.4 Clinicians should only consider opioids as an option for patients who have failed the aforementioned treatments and only if the potential benefits outweigh the risks for individual patients. Physicians are expected to have a discussion of the known risks and realistic benefits of opioids with their patients before prescribing them.4 Despite this recommendation, only 60.5% of patients nationally and 36.2% of patients in Massachusetts recall a discussion involving the risk of addiction with their physician.6

Significant side effects in those taking opioids compared to placebo include constipation (16%), nausea (15%), dizziness/vertigo (8%), somnolence (9%), vomiting (5%), and pruritis (4%).7 Other risks include dependence (3-26%),8 amnesia, insomnia, weight gain, sexual dysfunction, dry mouth, hyperhydrosis, urinary retention, cardiovascular issues, and death.9 Furthermore, concurrently taking an opioid with a benzodiazepine more than doubles a patient’s chance of hospital admission from an overdose (1.16% to 2.42%).10 Despite the increased risk, 60% of patients who are taking opioids are also taking benzodiazepines or muscle relaxants.9 In addition, chronic use of opioids frequently results in decreased efficacy of the drug and opioid-induced hyperalgesia.9

To better understand the shifting trends toward using opioids as a primary method for pain management, it is important to look at the statistical progression of this crisis and the methods taken to reverse the alarming direction of opioid negligence. In the 19th century, physician-scientists discovered that opiates such as morphine could reduce pain and chemist Felix Hoffmann developed aspirin from a substance in willow bark. However, it wasn’t until the past few decades that opioids became a mainstay for pain management.1

Rates of opioid pain reliever overdose death, treatment admissions, and kilograms sold.11

In 1996 Purdue Pharm began marketing OxyContin extended-release (long-acting), a schedule 2 narcotic/opioid, to physicians and the media. Sales representatives claimed that the risk of addiction was less than 1%.12 However, based on a retroactive study of 1.25 million patients, the highest probabilities of continued opioid use at 1 (27.3%) and 3 years (20.5%) were seen among patients who received long-acting opioid treatment.13 Contrary to Purdue Harm’s claims, the prevalence of abuse ranking is as follows: OxyContin ≥ hydrocodone > other oxycodone > methadone > morphine > hydromorphone > fentanyl > buprenorphine.14

Over the course of the first decade of the 21st century, prescription pain reliever sales and overdose death rates quadrupled.11 The admission rate for substance abuse treatment increased six-fold.11 Between 2002-2004, nearly 2/3 of heroin users reported non-medical use of opioids prior to initiation of heroin. That ratio increased to more than 4 of every 5 heroin users by 2008-2010.15

A 2007 meta-analysis on the efficacy of opioid use did not show a significant reduction in pain, compared to nonopiods or placebos.16 Despite the side effects and this lack of efficacy, an estimated 20% of patients presenting to physician offices with non-cancer pain symptoms or pain-related diagnoses (including acute and chronic pain) receive an opioid prescription.8

In 2007, the ACP and American Pain Society (APS) released the first clinical guidelines for treatment of low back pain. It included patient education, self-symptom management, and encouraging the patient to remain active as the first line of options.17 If unsuccessful, they recommend acetaminophen or NSAIDs in conjunction with the aforementioned education.17 Emphasis is also placed on discussing the risks of addiction if prescribing opioids. Opioid analgesics or tramadol are only suggested if NSAIDs have failed or if the pain is debilitating.17 Next, a patient is instructed to undergo spinal manipulation, interdisciplinary rehab, exercise therapy, acupuncture, massage therapy, yoga, cognitive-behavioral therapy, or progressive relaxation.17

Despite these evidence-based guidelines, in 2012, 259 million prescriptions were written for opioids, which is more than enough to give every American adult their own bottle of pills.18 Even though Americans comprise under 5% of the world’s population, Americans consume 80% of the opioids prescribed worldwide.9 In 2013, the cost of medical care and substance abuse treatment for opioid addiction and overdose was an estimated $78.5 billion.19

In 2014, 60.9% of drug overdose deaths in the US involved an opioid (28,647 deaths).20 Between 2014-2015 alone, the age-adjusted opioid-involved death rate increased by 15.6%.20 Drug overdoses are now the leading cause of death for those under 50 years of age in the US.9 More people are dying from drugs than HIV at the peak of it’s epidemic, auto accidents, and guns.9

In 2015, more than 1/4 million children aged 12-17 were using non-medical opioids and nearly half of them were clinically addicted.8 From 2015 to 2016, opioid overdose deaths increased 27.7%.21 In 2016, The Centers for Disease Control and Prevention released a 50 page report outlining guidelines for prescribing opioids for chronic pain.22 In February 2018 Purdue Pharma announces it will cease marketing efforts to physicians after making $36 billion in sales.23

Theoretically, opioids are prescribed to lower a patient’s pain and improve their functional ability. However, there was no significant difference in pain-related function compared to non-opioids over the course of 1 year.24 Furthermore, pain intensity was actually significantly less in the non-opioid group at 12 months.24 Even worse for opioids, the opioid group had twice the number of adverse side effects (1.8 vs. 0.9 symptoms) as the nonopioid group and was statistically significant. 24

Possible rationale for continued inflation of opioid prescriptions beyond best clinical judgement include initiation of pill mills where prescriptions are exchanged for cash, taking advantage of the addictive properties of opioids to ensure frequent return visits by patients, and naiveté of ACP or CDC guidelines.25 Further motivation to prescribe opioids are opioid company payments to physicians ($38,073,796 documented from August 2013-December 2015).26 Other sources have noted pressure from hospital organizations on physicians to prescribe opioids in order to improve Hospital Consumer Assessment of Healthcare Providers and Systems scores, and thus increase hospital payments by the Centers for Medicare and Medicaid Services.9

Prescribing physicians and pharmaceutical companies have been under scrutiny to implement changes and prevent drug-seeking behavior. Clinicians are on high alert to detect signs of abuse/misuse and to stay ahead of street-smart chemists who post on forums such as Abuse-deterrent opioids have sought to make modification of the drugs nearly impossible and avoid the sensation of euphoria or “the high.” Purdue’s version of the abuse-deterent OxyContin reduced addiction rates 27% among patients using OxyContin alone and 9% using OxyContin with other opioids.27 Additionally, pressure by Physicians for Responsible Opioid Prescribing seeks to have CMS remove pain-related questions from hospital ratings.9

The DEA has taken swift action in the past several years shutting down pain clinics and charging healthcare professionals with fraud. In July 2017 alone, 412 individuals were charged or suspended for $1.3 billion in fraudulent opioid-related billing activities.28 Since a Florida legilative initiative that combined regulatory and criminal laws was put in place, there has been a significant decline in pill mills, opioid diversion, overdose deaths, and opiods. Criminal investigations as well as a prescription drug monitoring program has led to a heightened standard of care and restrictions for pain management clinics.29

However, this leaves opioid-dependent patients without a segway to another clinician to manage their medications. This can lead to withdrawal, street-drug dependence, and even death.9 Abandoned patients must be strategically guided to medical professionals who will reduce the patient’s opioid dosage, address the psyche affiliated with the chronic pain, and transition the patient to a treatment of suboxone or methadone, if necessary, as both have been shown to be effective.30,31 It is imperative that the psychology of a chronic pain patient be assessed and addressed. There has shown to be increased emotional distress, alteration in cognition, and reduced quality of life that much be understood from a biopsychosocial perspective.32

Indicting physicians doesn’t seem to be an absolute solution, as the online pharmacy business is booming. 11,688 internet drug outlets are currently selling prescription medications to US patients.33 Of these, 11,142 (95.8%) were found to be operating out of compliance with state and federal laws.33  Many do not require a prescription, and about half are selling counterfeit painkillers and other fake medications. About 20 illegal online pharmacies are launched every day.33

To further aid drug manufacturers/distributors with imposed regulatory obligations, the DEA added a new feature to its ARCOS Online Reporting System, a comprehensive drug reporting system that monitors the flow of controlled substances from their point of manufacture through commercial distribution channels to the point of sale at the dispensing/retail level.34

The greatest focus should be on controlling the gate keeper in a multi-faceted approach. If patients are never exposed to an opioid in the first place, there will be less addiction, fewer opioids on the streets, and fewer people turning to heroin as a cheaper alternative. Because of the possibility of patients skewing their pain and functional outcome scores to demonstrate greater severity, it is also important to take into account other objective measures for pain and appropriateness for prescribing an opioid. One validated and reliable measure used to predict patient propriety for long-term opioid analgesic treatment for chronic noncancer pain is the DIRE (diagnosis, intractability, reliability with 4 parameters, and efficacy) scoring system.35,36 The benefit of the DIRE is that it also takes into account risk of opioid abuse/addiction by assessing variables of psychology, chemical health, and social support.35,36

Additionally, Dr. Forest Tennant devised an evidence-based patient assessment to guide the prescribing of opioids.37 Tennant outlines signs of excess sympathetic discharge that are prevalent in uncontrolled pain as well as objective measures to determine uncontrolled pain and opioid overmedication, such as pulse rate, blood pressure, pupil diameter, and temperature of the extremities. Similar strategies are used in functional capacity evaluations

to assess an individual’s ability to return to work.38

Considering the accruing healthcare costs, number of deaths, and lack of proven functional efficacy of the opioid epidemic, it should be the ethical duty of prescribing physicians, insurance companies, government, and pharmaceutical companies to enforce such evaluation standards for prescribing opioids.

The greatest conundrum of all is that, despite all the advancements in medicine and knowledge of treatment methods for pain, opioids have even been an acceptable mainstay option. The leading cause of accidental deaths in the US are prescription drugs.39 Therefore, it is imperative that safer alternative options become blatantly apparent to those in pain and those who manage the pain of others.
