Risk factors for alloimmunisation in the general patient population

Abstract

For hospitals providing services to regional populations, difficulties are associated with transferred patients with poorly communicated medical history and a risk of alloimmunisation. Identification of patients at risk would assist in treatment planning. A retrospective study of alloimmunised patients was undertaken, comparing the demographics and diagnoses of this population with a control patient population. A preponderance of diagnoses of Sepsis, Haematological Malignancy, GIT Bleeds and Renal Failure was demonstrated in the alloimmunised population. Consistent with prior studies, RhD negative patients and female patients were over-represented in the study group, which was also on average significantly older.
