Risk Factors For Adverse Outcomes In Solid Tumor Interhospital Transfer Patients.

191Background: We previously reported that inter-hospital transfer patients to our institution’s oncology service experienced higher mortality and increased length of stay (LOS) compared to other origins of admission. We sought to identify risk factors for adverse outcomes in this hospital transfer population. Methods: We reviewed all inter-hospital transfers from Jan-June 2016 to the Cleveland Clinic’s solid tumor oncology service. Patient characteristics, including age, albumin, and case severity indices (mortality and severity risk scores and AP-DRG), as well as encounter characteristics, including admitting provider (house staff or hospitalist), admission time (8AM-5PM or evening), admission day (weekday or weekend), and time between transfer acceptance and admission were recorded. Adverse events examined included activation of adult medical emergency team (AMET), ICU transfer, LOS, in-hospital mortality, and 30-day readmission. Associations of patient and encounter characteristics with adverse events...
