A retrospective analysis was conducted on patients with traumatic brain injuries (ICD-9-CM codes 800.20 - 801.86, 852.00 - 853.05) admitted between 2014 and 2016 at Genesys Regional Medical Center through the trauma service. From this group, the investigators selected patients admitted with traumatic SDH, and those patients were followed over the following 6 months as regards to readmission status. Patients who were readmitted versus patients who were not readmitted were compared. The risk of readmission within 6 months of discharge for SDH was analyzed adjusting for age, prior anticoagulation use, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), gender, time to readmission and co-morbid conditions which included diabetes mellitus, cardiovascular disease, renal disease, chronic obstructive pulmonary disease, and osteoporotic/orthopedic fractures using Cox Proportional Hazards Regression analysis.
