jvarisco posted the five motivational factors:
"Patients' Personal concerns- "fear of disease, infection, viral, etc. . "
Medical Reasons- patients' who can't receive blood, matching issues
Religious or Scriptural Beliefs-Jehovah's Witnesses, Jews, many others
Cost Effectiveness- Dan had this under clinical - "length of stay"
Blood Shortage - Donor population decreasing"

Improved Care is possibly a sixth reason. Nurse staffing shortages and nursing demands are affecting health care in many countries. South Africa is facing a crisis in nursing unparalleled in the West. Eliminating the consumption of time it takes to administer a transfusion and decreasing complications and stays is a major benefit to the nurses in any hospital.
