Complications related to blood donation: a population-based study

Area of Science:

• Transfusion Medicine
• Public Health
• Hematology

Background:

• Limited population-based data exists on blood donation complication rates and outcomes.
• Understanding donor complication risks is crucial for blood safety and donor retention.

Purpose of the Study:

• To determine the overall rate and types of complications associated with blood donation.
• To assess the incidence of moderate and severe donor complications, including those leading to long-term morbidity.

Main Methods:

• Utilized data from a 2003 regional survey in Aarhus County, Denmark, for overall complication rates.
• Incorporated nationwide data from the Danish Register of Complications Related to Blood Donation (1997-2003) for moderate and severe complications.

Main Results:

• A total of 340 complications (needle injuries, vasovagal reactions) were identified in 41,274 donations (824/100,000).
• Nationwide, 752 moderate/severe complications occurred among 2,575,264 donations (29/100,000).
• Long-term morbidity and disablement rates were 5/100,000 and 2.3/100,000 donations, respectively.

Conclusions:

• The overall risk of blood donation complications is low.
• While rare, complications leading to long-term morbidity and disablement necessitate continued monitoring and attention.
