Purpose: Hospital transfers may affect clinical outcomes. Evaluation of admission by source of transfer, time of admission, and provider type may identify opportunities to improve inpatient outcomes.
Methods: We reviewed charts of patients admitted to the solid tumor oncology service between July and December 2014 from the Cleveland Clinic Foundation (CCF) Main Campus emergency department (ED), CCF Regional EDs, outside hospital (OSH) ED, OSH inpatient services, and CCF outpatient clinics. Data collected included time of admission, mortality and severity risk scores, and provider type. Risk factors were assessed for clinical outcomes, including activations of the Adult Medical Emergency Team, intensive care unit transfers, in-hospital mortality, and length of stay (LOS).
Results: Five hundred admissions were included. OSH inpatient transfers had significantly higher disease severity compared with all other origins of admission. OSH inpatient transfers demonstrated significantly longer LOS compared with all other origins of admission, and higher mortality rates compared with the outpatient direct admits and CCF Main Campus ED admits. After adjusting for disease severity and risk of mortality, OSH ED patients remained at higher risk for Adult Medical Emergency Team activation, OSH inpatient transfers had the longest LOS, and CCF Main Campus ED patients had the lowest risk of mortality. Time of admission and provider type were not associated with any of the outcomes.
Conclusion: Oncology inpatients transferred from an outside health care facility are at higher risk for adverse outcomes. The magnitude of difference is lessened, but still significant, after adjustment for disease severity and risk of mortality.
