Characteristics of ambulatory spine care visits in the United States, 2009–2016

Abstract

BACKGROUND: Back pain is a leading reason for seeking care in the United States (US), and is a major cause of morbidity. OBJECTIVE: To analyze demographic, patient, and visit characteristics of adult ambulatory spine clinic visits in the United States from 2009–2016. METHODS: Data from the National Ambulatory Medical Care Survey from 2009–2016 were used and were sample weighted. RESULTS: Most patients presenting for ambulatory spine care were 45–64 years (45%), were most commonly female (56.8%), and private insurance (45%) and Medicare (26%) were most common payors. The percentage of visits for spine care done at a primary care setting was 50.1% in 2009–2010 and 48.3% in 2014–2015. Approximately 15.5% were seen in orthopedic surgery clinics in 2009–2010 and 7.3% in 2015–2016. MRI was utilized in 11.7% in 2009–2010 and 11.0% in 2015–2016. Physical therapy was prescribed in 13.2% and narcotic analgesic medications were prescribed in 36.2% of patients in 2015–2016. CONCLUSIONS: MRI was used more frequently than guidelines recommended, and physical therapy was less frequently utilized despite evidence. A relatively high use of opiates in treatment of back pain was reported and is concerning. Although back pain represents a substantial public health burden in the United States, the delivery of care is not evidence-based.
