Numbers of adults (>18 years) with different conditions in the Medical Expenditure Panel Survey (MEPS) data

  Number of adult individuals* Percent of US adults Percent of adult medical events
Surveyed in MEPS & with medical events (2003–2015) 130,767 100.0% 100.0%
With at least one spinal (CCC 205 or ICD-9 of 846 or 847) event 17,776 16.9% 27.4%
With chronic spinal pain 5,824 6.0% 13.8%
With chronic spinal pain & with impact level (SF-12) data available 5,151 5.3% 12.6%
    With chronic low-back pain (ICD-9 724) & impact level (SF12) data available 3,457 3.6% 8.5%
    With chronic neck pain (ICD-9 723) & impact level (SF12) data available 778 0.8% 2.2%
    With pain from chronic sacroiliac sprain/strain (ICD-9s 846 and 847) & impact level (SF-12) data available 428 0.4% 1.1%
With chronic spinal pain & predicted to have low impact chronic spinal pain 2,100 2.4% 5.3%
With chronic spinal pain & predicted to have moderate impact chronic spinal pain 967 1.1% 2.7%
With chronic spinal pain & predicted to have high impact chronic spinal pain 2,401 2.2% 5.8%

CCC 205 = Clinical Classification Code that includes “Spondylosis, intervertebral disc disorders & other back problems”; ICD-9 = International Classification of Diseases, 9th Revision; SF-12 = 12-item short form of the Medical Outcomes Survey

*

The total number of individuals across each chronic pain impact level sum to more than are shown as having chronic spinal pain and SF-12 data because some individuals experienced different chronic pain impact levels across their two years of data.
