Jeon MS, et al. - Researchers examined elderly people undergoing cancer surgery for the association between pre-operative medication use and unplanned 30-day readmission. Using univariate and multivariate analyses, variables between patients with readmission and those without readmission were compared. Among 473 included patients, 30-day readmission was observed in significant correlation to pre-operative discontinuation-requiring medications and gastrointestinal/hepato-pancreato-biliary cancer. This indicates the influence of medication use on unplanned 30-day readmission in geriatric oncology patients and highlights the significance of medication optimization for elderly patients with cancer surgery.
