| According to a new review published in theJournal of Pain, the National Health Interview Survey (NHIS) is the best single surveillance source for monitoring chronic pain data in the United States. The NHIS is an annual interview survey that collects household health data representing the U.S. civilian, noninstitutionalized population. The review was conducted by researchers from the Centers for Disease Control and Prevention; the National Center for Complementary and Integrative Health (NCCIH); Kaiser Permanente Washington, Health Research Institute; Oak Ridge Institute for Science and Education; the Office of Pain Policy, National Institutes of Health; and Stanford University School of Medicine. Monitoring the prevalence of chronic pain and how it is managed is especially important now because the opioid crisis has led to changes in pain treatment. For instance, health care providers are prescribing opioids less often and using new drug and nondrug treatment options instead. These treatment changes could either help or hurt those with pain. |
