For a study, the researchers aimed to compare the length of stay (LOS) and discharge disposition of adult spinal deformity (ASD) patients undergoing surgery before and during the pandemic. Patients who underwent ASD surgery during the pandemic were younger (61 vs 67 years) and were found to have longer fusion constructs (9 vs 8 levels) compared with before the pandemic (P<0.05 for both). Patients who underwent surgery during the pandemic resulted in shorter LOS (6 vs 9 days) and were more likely to be discharged home (70% vs 28%) (P<0.05 for both). After controlling for age and levels fused on multivariable regression, patients who underwent surgery during the pandemic had shorter LOS (IRR=0.83, P=0.015) and greater odds of home discharge (odds ratios [OR]=7.2, P<0.001). Notably, no differences in major complications, reoperations, readmissions, or emergency department (ED) visits between the 2 groups were detected. During the COVID-19 pandemic, LOS for patients who underwent thoracolumbar ASD surgery decreased, and more patients were discharged home without adversely affecting complication or readmission rates. Lessons learned during the pandemic might help improve resource utilization without negatively influencing short-term results.
