What are the predictors of emergency department utilization and readmission following extremity bone sarcoma resection?

ABSTRACT

INTRODUCTION: Treatment for bone sarcomas are large undertakings. Emergency department (ED) visits and unplanned hospital readmissions are a potential target for cost containment. The purpose of this study was to evaluate the risk factors for ED visits and unplanned readmissions following extremity bone sarcoma surgery. METHODS: Data from Optum Labs Data Warehouse, a national administrative claims database, was analyzed to identify patients with extremity bone sarcomas from 2006 to 2017. Multivariable logistic regression was used to identify factors associated with ED visits and readmissions. RESULTS: Of 1390 (743 males, 647 female) adult patients, 137 (12%) visited the ED and 245 (18%) were readmitted within 30 days of discharge. The most common indication for ED visits (n = 63, 45.9%) and readmission (n = 119, 48.5%) were complications of surgery. Length of stay >10 days was associated with ED utilization (OR, 1.83; P = .01) and readmission (OR, 4.47; P < .001). CONCLUSION: One in ten patients will use the ED, and one in five patients will be readmitted to the hospital within 30 days of discharge following extremity bone sarcoma surgery. Length of stay was associated with ED visits and readmission. These patients could be targeted with alternative management strategies in the outpatient setting with early clinical follow-up to minimize readmission.
