Chronic pain is common among veterans treated in Veterans Health Administration (VHA) facilities, and optimal management remains challenging in the context of the national opioid misuse epidemic. The Eastern Oklahoma VA Health Care System (EOVAHCS) Pain Program offers a range of services that allow clinicians to tailor multimodal treatment strategies to a veteran’s needs. In 2014, a Modality Clinic was established to assess the utility of adding noninvasive treatment devices to the pain program’s armamentarium. This article addresses the context for introducing these devices and describes the EOVAHCS Pain Program and Modality Clinic. Also discussed are procedures and findings from an initial quality improvement evaluation designed to inform decision making regarding retention, expansion, or elimination of the EOVAHCS noninvasive, pain treatment device program.
Opioid prescriptions increased from 76 million in 1991 to 219 million in 2011. In 2011, the annual cost of chronic pain in the US was estimated at $635 billion.1-6 The confluence of an increasing concern about undertreatment of pain and overconfidence for the safety of opioids led to what former US Surgeon General Vivek H. Murthy, MD, called the opioid crisis.7 As awareness of its unintended consequences of opioid prescribing increased, the VHA began looking for nonopioid treatments that would decrease pain intensity. The 1993 article by Kehlet and Dahl was one of the first discussions of a multimodal nonpharmacologic strategy for addressing acute postoperative pain.8 Their pivotal literature review concluded that nonpharmacologic modalities, such as acupuncture, cranial manipulation, cranial electrostimulation treatment (CES), and low-level light technologies (LLLT), carried less risk and produced equal or greater clinical effects than those of drug therapies.8
Electrical and Cold Laser Modalities
Multimodal treatment approaches increasingly are encouraged, and nonopioid pain control has become more common across medical disciplines from physical therapy to anesthesiology.8-10 Innovative, noninvasive devices designed for self-use have appeared on the market. Many of these devices incorporate microcurrent electrical therapy (MET), CES, and/or LLLT (also known as cold laser).11-16 LLLT is a light modality that seems to lead to increased ATP production, resulting in improved healing and decreased inflammation.13-16 Although CES has been studied in a variety of patient populations, its effectiveness is not well understood.16 Research on the effects of CES on neurotransmitter levels as well as activation of parts of the brain involved in pain reception and transmission should clarify these mechanisms. Research has shown improvements in sleep and mood as well as overall pain reduction.11,16 Research has focused primarily on individual modalities rather than on combination devices and has been conducted on populations unlike the veteran population (eg, women with fibromyalgia).
Most of the devices that use electrical or LLLT cannot be used safely by patients who have implantable electrical devices or have medical conditions such as unstable seizures, pregnancy, and active malignancies.
The most common adverse effects (AEs) of CES—dizziness and headaches—are minimal compared with the AEs of pain medications. MET and LLLT AEs generally are limited to skin irritation and muscle soreness.11 Most devices require a prescription, and manufacturers provide training for purchase.
