Abbott: New Study Shows Spinal Cord Stimulation Can Reduce, Stabilize Opioid Use Among Chronic Pain Patients

Researchers found that opioid use declined or stabilized in 70 percent of patients who received a spinal cord stimulation system.

New research has found spinal cord stimulation (SCS) therapy can be key to reducing or stabilizing the use of opioids in patients battling chronic pain.


In a new study, researchers examined opioid usage data from more than 5,400 patients both prior to and after receiving an SCS system implant. In an SCS system, an implanted device similar to a pacemaker delivers low levels of electrical energy to nerve fibers, interrupting pain signals as they travel to the brain to reduce the sensation of pain. Researchers have found that average daily opioid use declined or stabilized for patients receiving a successful SCS system compared to patient use of opioids prior to an implant.

In addition, while opioid usage was not different for the two groups at time of implant, patients who underwent a successful SCS implant had significantly lower opioid use one year after their implant. Patients who had their SCS system removed saw their opioid use increase again over time.

The study, which the researchers believe makes a compelling case for considering SCS therapy earlier in the chronic pain care continuum, were presented at the 2017 North American Neuromodulation Society (NANS) annual meeting by Ashwini Sharan, M.D., director of Functional and Epilepsy Surgery at Vickie and Jack Farber Institute for Neuroscience at Jefferson and president of NANS.  The study was sponsored by Abbott (No. 14 on the DiversityInc Top 50 Companies list), a global leader in the development and manufacture of SCS systems and therapy options, such as the company's proprietary BurstDR™ stimulation.

Currently, more than 2.1 million people in the U.S. suffer from substance abuse related to opioid pain relievers, while worldwide an estimated 15.5 million people are now classified as opioid dependent. Chronic pain is often a driver of opioid use as patients seek relief and improvements to their quality of life. Fortunately for patients, SCS therapy has been clinically proven to offer meaningful relief to patients suffering from chronic pain.

"Given the epidemic of opioid addiction and abuse, these findings are important and confirm that spinal cord stimulation therapy can offer strong benefits for patients struggling with chronic pain," said Sharan. "Based on these results, we concluded it may be possible to improve outcomes by offering our patients spinal cord stimulation earlier, before opioid dependence and addiction can occur."

About the Study:

For their analysis, the research team assessed private and Medicare insurance claims data from 5,476 patients who received an SCS system to treat chronic pain associated with a host of conditions (excluding pain related to cancer). The data were collected between January 2010 and December 2014.

The data confirmed that many patients are often prescribed increasing dosages of opioids prior to receiving an SCS system. The researchers also found:

  • SCS therapy is effective for patients at any level of opioid usage prior to implantation.
  • Opioid use declined or stabilized in 70 percent of patients who received an SCS system.
  • Among patients who had their SCS system explanted, opioid use was higher at one year compared to those who continued with SCS therapy.

The researchers further suggested patient outcomes could be improved if SCS were implanted earlier in recognition of the clinical practice to provide increasing dosages of opioids over time. These conclusions help build upon prior research, such as results of a large multi-center randomized controlled trial in patients with failed back surgery syndrome (FBSS) that showed trends in opioid reduction or cessation among SCS patients. In addition, new technologies released in the U.S. in 2015 and 2016 hold promise to improve outcomes further and may reduce common complications resulting in explant such as the undesired changes in paresthesia, issues with charging, pain at the implantable pulse generator (IPG) site, and loss of pain relief.

"As our society has been seeking ways to stem opioid abuse and addition, our company offers treatment options that can reduce their exposure to opioid medication," said Allen Burton, M.D., medical director of neuromodulation at Abbott. "Data like these are critical to helping us demonstrate that spinal cord stimulation can reduce exposure to opioids while giving patients comprehensive pain relief."

Abbott's Xience Sierra Heart Stent Receives National Reimbursement in Japan to Treat People with Coronary Artery Disease

Coronary artery disease is the most common form of heart disease, which is the second leading cause of death in Japan.

Originally Published by Abbott.

Abbott announced that Japan's Ministry of Health Labour and Welfare (MHLW) granted national reimbursement for XIENCE Sierra™, the newest generation of the company's gold-standard XIENCE everolimus-eluting coronary stent. XIENCE Sierra improves upon previous versions of XIENCE with an enhanced stent design, a new delivery system, and unique sizes to help doctors treat challenging cases.

XIENCE Sierra was designed to help doctors more easily treat people with difficult-to-treat blockages that involve multiple or totally blocked arteries or complications such as diabetes. Complex cases are increasingly prevalent as people with coronary artery disease are living longer.

"Extensive clinical data and 10 years of real-world experience with the XIENCE family of stents provide doctors with confidence that they are treating their patients with one of the safest stents available," said Chuck Brynelsen, senior vice president of Abbott's vascular business. "National reimbursement of XIENCE Sierra will provide people in Japan with greater access to this life-changing technology that can help them live their best lives."

Coronary artery disease is the most common form of heart disease, which is the second leading cause of death in Japan. National reimbursement in Japan will enable doctors to treat more patients with XIENCE Sierra through the country's health insurance plans. XIENCE Sierra was approved in Japan on April 4, 2018, received CE Mark in Europe late last year, and is under review with the U.S. Food and Drug Administration.

XIENCE has been studied in over 100 clinical trials and in 10 years of global real-world experience. Its safety profile is unprecedented with consistent low rates of stent thrombosis, even in complex cases. More than eight million people worldwide have received a XIENCE stent since its initial regulatory approval.
