RICHMOND, Va., April 15, 2016 /PRNewswire/ -- Indivior Inc., a subsidiary of Indivior PLC (LON: INDV), presented new research from an analysis of more than 100,000 commercially insured patients indicating underutilization of treatment methods for patients with opioid use disorder (OUD), suggesting a growing need for improved access to medication-assisted treatment (MAT). Findings were presented in a poster session today at the American Society of Addiction Medicine 47th Annual Conference in Baltimore.
In a retrospective observational study, researchers analyzed administrative claims from the Truven Health MarketScan® Commercial Database among 103,768 commercially insured patients with OUD between 2008 and 2014, with a mean duration of follow up of 702 days. As one of the largest studies of this kind, researchers found that post-diagnosis, nearly one-third (31.6 percent) of patients were receiving no opioid dependence treatment. Further, less than half (42.8 percent) of patients were prescribed MAT, with buprenorphine/naloxone being the most commonly prescribed (34.4 percent of the overall OUD patients).i
"The study revealed that almost one-quarter (24.3 percent) of patients diagnosed with OUD received a recommended method of treatment, both MAT and psychosocial care, reaffirming my observations in clinical practice that treatment access continues to be an issue,"ii said Dr. Bernd Wollschlaeger, MD, FAAFP, FASAM, Aventura Family Health Center. "I'm optimistic that with continued research and community support, we can work together to help ensure MAT is accessible to appropriate patients, when and where they need it, and psychosocial care is provided to help support them in their journey."
A majority of patients received OUD-related care in the outpatient setting. Of these, almost one-quarter of patients (22.9 percent) visited a psychiatrist and almost one-third (31.1 percent) visited a primary care physician. The researchers also found that the pre-treatment study population had higher rates of pain-related conditions (chronic pain: 48.6 percent, narcotic pain medications: 53.1 percent) and psychiatric comorbidities (depressive disorders: 24.0 percent, prescriptions of antidepressants: 42.7 percent). The researchers recommend additional studies to better understand factors impacting the way patients receive and access treatment. Identifying these factors may help strengthen future community-based programs to address existing treatment gaps in clinical settings.
"Indivior is pleased to share these findings at the ASAM Annual Conference, as these insights bring us one step further in evolving the way we understand, interpret and respond to the barriers patients face in their journey," said Dr. Tim Baxter, Chief Medical Officer, Indivior. "We look forward to expanding upon this research and sharing additional data at future congresses so that we can work with the medical community to find new ways to better connect patients to treatment."
About the Study Design
The intent of the study was to illustrate a comprehensive, real-world view of the characteristics, clinical burden and treatment received across men (57 percent) and women (43 percent) of diverse ages, with a mean age of 36 years. The study time period (index date) was defined as the earliest date with a diagnosis of opioid dependence between January 1, 2008 and March 31, 2014. Patient demographics were measured on the index date. A six month pre-index period was used to measure baseline patient clinical characteristics, including the Deyo-Charlson Comorbidity Index, comorbid conditions and concomitant medications. Researchers also evaluated the type of OUD treatment received (i.e., detoxification, psychosocial treatment, and MAT) from each patient's healthcare claims.
