Researcher at National Health Insurance Service Ilsan Hospital Releases New Data on Reoperation (Risk factors for unplanned reoperation after corrective surgery for adult spinal deformity): Surgery – Reoperation

NewsRx Medical Devices Daily

2023 APR 19 (NewsRx) -- By a News Reporter-Staff News Editor at NewsRx Medical Devices Daily -- Data detailed on reoperation have been presented. According to news reporting out of Goyang, South Korea, by NewsRx editors, research stated, “To determine the major risk factors for unplanned reoperations (UROs) following corrective surgery for adult spinal deformity (ASD) and their interactions, using machine learning-based prediction algorithms and game theory.”

The news reporters obtained a quote from the research from National Health Insurance Service Ilsan Hospital: “Patients who underwent surgery for ASD, with a minimum of two-year follow-up, were retrospectively reviewed. In total, 210 patients were included and randomly allocated into training (70% of the sample size) and test (the remaining 30%) sets to develop the machine learning algorithm. Risk factors were included in the analysis, along with clinical characteristics and parameters acquired through diagnostic radiology. Overall, 152 patients without and 58 with a history of surgical revision following surgery for ASD were observed; the mean age was 68.9 years (SD 8.7) and 66.9 years (SD 6.6), respectively. On implementing a random forest model, the classification of URO events resulted in a balanced accuracy of 86.8%. Among machine learning-extracted risk factors, URO, proximal junction failure (PJF), and postoperative distance from the posterosuperior corner of C7 and the vertical axis from the centroid of C2 (SVA) were significant upon Kaplan-Meier survival analysis.”

According to the news editors, the research concluded: “The major risk factors for URO following surgery for ASD, i.e. postoperative SVA and PJF, and their interactions were identified using a machine learning algorithm and game theory. Clinical benefits will depend on patient risk profiles. Cite this article: Bone Joint Res 2023;12(4):245-255.”
