    BackgroundLumbar Spine MRI Use for Low Back Pain (OP-8) is calculated by dividing the number of patients who received lumbar magnetic resonance imaging (MRI-L) before receiving alternative treatments (e.g., physical therapy) by the total number of patients receiving MRI-L in the outpatient setting at a given institution. Since the passage of the Post-Medicare Access and CHIP Reauthorization Act of 2015 (MACRA), OP-8 scores became tied to hospital finances. This study aims to determine how MACRA has impacted OP-8 scores since its implementation. We also aim to investigate how regional designation, profit status (for-profit, government, and nonprofit), and hospital setting (critical access, non-critical access) affect OP-8 scores.MethodsData from the Centers for Medicare and Medicaid Services Hospital Compare database were used to extract information on the national trends in OP-8 scores from 2014 to 2020. A multivariable linear regression model was fit to isolate the impact of hospital characteristics on OP-8 scores.ResultsAfter a decrease from 2015 to 2016, the mean national OP-8 score plateaued, staying around 40% from 2017 through 2020. A critical access setting increased OP-8 scores by 5.41 (95% confidence interval, 3.51-6.77; P ≤ 0.001), compared with a non-critical access setting. Governmental status increased scores by 1.27 (95% confidence interval, 0.28-2.27; P = 0.012), compared with a nonprofit status.ConclusionsThe implementation of MACRA seems to have been unsuccessful in altering practice patterns, given the minimal change in OP-8 scores over the last 4 years. Furthermore, institutional factors are clearly correlated with a lack of adherence to magnetic resonance imaging guidelines. Given these findings, there is a need to modify health policies.Copyright © 2021 Elsevier Inc. All rights reserved.
