Krebs et al.. Effect of Opioid vs Nonopioid Medications on Pain-Related Function in Patients With Chronic Back Pain or Hip or Knee Osteoarthritis Pain: The SPACE Randomized Clinical Trial. JAMA 2018. 319:872-882. PMID: 29509867. DOI. Full Text.

Bottom Line

A landmark study was published in 2018 by Krebs et al - the SPACE study. It was a pragmatic randomised controlled trial comparing opioid versus non opioid analgesics for 12 months in primary care. Participants were 240 VA patients with moderate to severe chronic back pain or knee/hip OA, and not on opioids. The mean pain intensity initially was 5.4 in both arms. Pain scores at 1 year was worse in the opioid arm (4.0) than non opioid (3.5) (P=0.034). There was no difference in pain interference, and adverse effects were worse in opioid group (P=0.03).
