Trends in Prescribing of Non-steroidal Anti-inflammatory Medications in the US Ambulatory Care Setting From 2006 to 2016

Abstract

While opioid prescribing has significantly decreased from a peak in 2012, less is known about the national utilization of non-opioid analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen (APAP) in the context of the opioid crisis. The objective of this study is to characterize the prescribing trends of NSAIDs and APAP in the US ambulatory care setting. We conducted repeated cross-sectional analyses using the 2006–2016 National Ambulatory Medical Care Survey. NSAID-involved visits were defined as patient visits among adults in which NSAIDs were ordered, supplied, administered, or continued. We used similarly-defined APAP visits as a referent group for context. After excluding aspirin and other NSAID/APAP combination products containing opioids, we calculated the annual proportion of NSAID-involved visits among all ambulatory visits. We conducted trend analyses using multivariable logistic regression adjusted for years, patient, and prescriber characteristics. From 2006 to 2016, there were 775.7 million NSAID-involved visits and 204.3 million APAP-involved visits. Most NSAIDs-involved visits were from patients aged 46–64 years (39.6%), female (60.4%), White (83.2%), and having commercial insurance (49.0%). There were significant increasing trends for the proportion of NSAID-involved visits (8.1–9.6%) and APAP-involved visits (1.7–2.9%) (both P < .0001). We observed an overall increase in NSAID and APAP-involved visits in US ambulatory care settings from 2006 to 2016. This trend may be attributed to decreasing opioid prescribing and raises safety concerns related to acute or chronic NSAID and APAP use. PerspectiveThis study shows an overall increasing trend in NSAID use reported in nationally representative ambulatory care visits in the United States. This increase coincides with previously reported significant decreases in opioid analgesic use, particularly after 2012. Given the safety concerns related to chronic or acute NSAID use, there is a need to continue monitoring the use trends of this class of medication.
