A Cross-Sectional Study of Blood Donors' Psychological Characteristics over 8 Weeks.

Background: Previous studies suggest that blood donation impacts blood donors' psychological state, with either positive or negative effects, such as feeling more energetic or more exhausted. It has not yet been described how long these effects last.

Materials And Methods: This prospective cohort study consisted of a qualitative and a quantitative part: (1) Psychological characteristics which changed after blood donation were identified by structured interviews of regular whole blood donors ( = 42).

A population-based longitudinal study on the implication of demographic changes on blood donation and transfusion demand.

Transfusion safety includes the risk of transmission of pathogens, appropriate transfusion thresholds, and sufficient blood supply. All industrialized countries experience major ongoing demographic changes resulting from low birth rates and aging of the baby boom generation. Little evidence exists about whether future blood supply and demand correlate with these demographic changes.

A population-based longitudinal study on the implications of demographics on future blood supply.

Background: Changes in demographics with increases in older age groups and decreases in younger age groups imply an increased demand for blood transfusions paralleled by a decrease in the population eligible for blood donation. However, more restrictive transfusion triggers and the patient blood management initiative also reduce the demand for red blood cells (RBCs). Eastern Germany is a model region for the impact of demographic changes, which manifest in this region approximately 10 years earlier than in other regions due to the 50% birth rate decline after 1989.

Impact of demographic changes on the blood supply: Mecklenburg-West Pomerania as a model region for Europe.

Background: The population structure in most European countries is currently changing with a shift from younger to older age groups. This study analyzed how demography will determine future blood demand and supply in a well-characterized region.

Study Design And Methods: The population of the main catchment area of the University Hospital Greifswald (415,000 inhabitants) was projected to the year 2015 based on 1-year age groups provided by the population registry, based on 2002 rates assuming stable death rates and migration patterns.
