Cases requiring ABO-incompatible transfusion and inhospital-donated blood transfusion.

Year	Age	Gender	Disease	Treatment	Shock Index	Outcome	Blood type	ABO-incompatible transfusion	unit	Inhospital blood transfusion (unit)
2016	83	F	Bleeding duodenal ulcer	Endoscopic surgery and laparotomy	Class I	Survive	A^+	O^+	2	2
2019	86	M	Bleeding after left artificial joint replacement surgery	Emergency operation	Class II	Survive	B^+	O^+	8	8
2022	48	M	Abdominal cattle trauma	Helicopter transport	Class II	Death	B^+	O^+	6	4
2022	70	M	Bleeding gastric ulcer	Endoscopic surgery	Class II	Death	A^+	O^+	6	18

Profiles of patients who underwent an inhospital homologous transfusion, followed by an ABO-incompatible transfusion, are presented. There was one case in the preintervention period, but this increased to three cases in the postintervention period, indicating that the number of cases of ABO-incompatible transfusion increased in the postintervention period. However, two of the three postintervention cases died. It may be necessary to re-evaluate the indications for blood transfusion in these fatal cases.
