RESUMEN
STUDY DESIGN: Level 3 retrospective database study. OBJECTIVE: This study aims to compare work RVU (wRVU), practice expense RVU (peRVU), malpractice RVU (mpRVU), and inflation-adjusted facility price alongside MS-DRG relative weight length of stay (LOS) for cervical spine fusions between 2011 and 2023. SUMMARY OF BACKGROUND DATA: Both RVU and MS-DRG reimbursement have been studied in various surgical subspecialties; however, little investigation has centered on cervical spine fusions. To the best of our knowledge, this is the first study to investigate trends in RVU and MS-DRG reimbursement in cervical spine fusion throughout the COVID-19 pandemic. METHODS: Center for Medicaid and Medicare Services (CMS) physician fee schedule was queried between 2011 and 2023 for RVU and facility reimbursement using common single and multilevel anterior and posterior cervical fusion codes. RVU facility prices were inflation adjusted to 2023. MS-DRG reimbursement data from 2011 to 2022 were compiled for cervical spinal fusion procedures with major complication or comorbidity (MCC) 471, complication or comorbidity (CC) 472, and without CC/MCC 473. Compound annual growth rates (CAGRs), Mean Annual Change, and yearly percent changes were calculated. RESULTS: No changes in wRVU were seen for all cervical CPT codes; however, the CAGR of peRVU (-0.51%±0.60%) and mpRVU (0.69%±0.41%) demonstrated marginal fluctuations. Every CPT code displayed an inflation-adjusted facility price decrease (-2.18%±0.24%). When assessing MS-DRG, there were marginal changes in geometric mean LOS (0.17%±0.45%), arithmetic mean LOS (-0.15%±0.84%), and relative weight (1.09%±0.68%). Unlike RVU reimbursement, the yearly percent change differs between each MS-DRG code. CONCLUSIONS: Inflation-adjusted RVU reimbursement facility prices demonstrated a consistent decrease, while DRG code reimbursement stayed relatively consistent over the study period. This data may help surgeons and hospitals become cognizant of temporal variations in reimbursement patterns as it may affect their personal practice. LEVEL OF EVIDENCE: Level III retrospective study.
RESUMEN
PURPOSE OF REVIEW: Social determinants of health (SDH) are factors that affect patient health outcomes outside the hospital. SDH are "conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks." Current literature has shown SDH affecting patient reported outcomes in various specialties; however, there is a dearth in research relating spine surgery with SDH. The aim of this review article is to identify connections between SDH and post-operative outcomes in spine surgery. These are important, yet understudied predictors that can impact health outcomes and affect health equity. RECENT FINDINGS: Few studies have shown associations between SDH pillars (environment, race, healthcare, economic, and education) and spine surgery outcomes. The most notable relationships demonstrate increased disability, return to work time, and pain with lower income, education, environmental locations, healthcare status and/or provider. Despite these findings, there remains a significant lack of understanding between SDH and spine surgery. Our manuscript reviews the available literature comparing SDH with various spine conditions and surgeries. We organized our findings into the following narrative themes: 1) education, 2) geography, 3) race, 4) healthcare access, and 5) economics.
