Editor’s Note: We’re proud to announce that Dr. Daniel Alford will speak on the topic of “Best Practices in Treating Opioid Use Disorders with Medications” at this fall’s Addiction Medicine continuing medical education course, presented by the Division on Addiction through Harvard Medical School. In today’s article, we review research from Dr. Alford and his colleagues at the Clinical Addiction Research and Education (CARE) Unit at the Boston University School of Medicine.
People who struggle with chronic pain often experience daily difficulties, such as depression and anxiety symptoms, sleep disturbance, substance use, and increased use of healthcare systems. Because chronic pain is difficult to treat, patients might seek relief outside of typical medical pathways. This week, STASH reviews a study by Daniel Alford and his colleagues that looks at the prevalence of primary care patients with chronic pain and pain related dysfunction, as well as a history of self-medication with substances.
What is the research question?
How many primary care patients with recent drug use have chronic pain and use substances to manage it?
What did the researchers do?
Alford and his colleagues enrolled 589 primary care patients with at least one self-reported instance of illicit drug use or prescription drug misuse in the past 3 months. The researchers asked patients about their chronic pain, pain-related dysfunction, substances used to treat pain, mental health, and demographic information.
What did they find?
About 84% of patients reported having any kind of chronic pain, and 74% of patients reported having pain-related dysfunction. In all, 51% of patients who reported using marijuana, cocaine, or heroin during the last 3 months reported that they did so in order to treat their pain. Furthermore, 81% of patients who misused prescription medication, and 38% of patients who heavily used alcohol, stated that they did so to treat their pain (Figure 1).
Why do these findings matter?
Substance misuse for chronic pain is a serious public health concern. Some people who have chronic pain might become dependent on opioids or other substances, prescribed or not. The recent coverage of the opioid epidemic has shed some light on how prescribing opioids can be potentially harmful to some patients, but one study shows that treating drug dependence alone is not enough when chronic pain is still an underlying issue. The misuse/abuse of these substances can lead to fatal drug overdoses and other dangerous health problems.
Every study has limitations. What about this one?
The results are all based on self-reported statements, which could be wrong. Additionally, this study does not show that chronic pain caused substance use, though a majority of patients reported that this was their experience. A longitudinal study—a study that follows the same people over time—could help us understand and combat the misuse of substances to treat chronic pain.
