Brief Summary
In this study, the investigators will be evaluating the impact of red blood cell age in patients receiving chronic blood transfusions in the outpatient setting. This study will have a double-bind, randomized trial design, meaning that the investigators and participants will not be told the group assignment at study enrollment. Study participants will be randomly divided into two groups (50% of participants in each group) by a computer generated block randomization schema. The 'fresh blood' group will receive blood units that are 7 or less from the time of donor collection, and the 'aged blood' group will receive blood units that are greater than 21 to 42 days from the time of donor collection. The number of units of blood transfused will be decided based on the participant's hemoglobin level before blood transfusion. The primary goal of our study is to compare annual red blood cell product use (the number of units given per patient in a year). The investigators will also be comparing groups to evaluate the transfusion reaction frequency, iron burden (based on the level of ferritin in the blood), overall transfusion and care cost difference, and participant time spent in outpatient departments. Our hypothesis is that use of fresh blood in chronically transfused patients will lead to a decrease the in red cell transfusion rate, with subsequent clinical benefits including reduction of transfusion reaction frequency and systemic iron burden. This study will be taking place within the Calgary Zone of Alberta Health Services only.

Study Arms (2)
Fresh Human Red Blood Cells
ACTIVE COMPARATORParticipants will receive transfusion of human donor red blood cells that are less than or equal to 7 days of age from the time of donation.
Aged Human Red Blood Cells
ACTIVE COMPARATORParticipants will receive transfusion of human donor red blood cells that are greater than 21 days and up to a maximum of 42 days of age from the time of donation.
Interventions
Red cell units for transfusion will be acquired from Canadian Blood Services (CBS), as a part of their usual stock to the Calgary Zone. Blood will be processed and prepared by CBS according to their standard protocol. The red cell units assigned to patients as a part of this trial will not be manipulated in any way prior to participant transfusion.

Eligibility Criteria
You may qualify if:
- Patients requiring outpatient chronic red cell transfusions (2 or more red blood cell units per month for at least 3 consecutive months) in an ambulatory clinic within the Calgary Zone
You may not qualify if:
- prerequisite for fresh or irradiated blood due to a pre-existing medical reason
- hemodialysis dependence
- chronic disease that has acutely decompensated, with a life expectancy of less than 3 months
