We investigated the occurence and causes of anaemia and other haematological abnormalities in 142 elderly patients (43 men, 99 women; median age 79 and 80 years), admitted to long-term care. Healthy 81-year-old subjects (n = 220) were used as reference group. Anaemia according to the WHO definition was much more common in the studied population (41%) than in a representative sample of 81-year-old subjects (10%). Somatically fit patients were less often anaemic (30%) than those with somatic illness (68%). The main causes for anaemia were: chronic disease (14.9%), recent haemorrhage (7.8%), iron deficiency (5.7%); and often multifactorial. Secondary leuko- or thrombocytosis occurred in 14 and 23%, drug-induced thrombocytopenia in 2.8% of the patients. Anaemia and other haematological abnormalities seen in elderly patients hospitalized for long-term care are often secondary to chronic or acute disorders. However, they also occur in patients without severe somatic impairment and many of them are reversible. Such findings should therefore not be neglected, but properly investigated, and if possible treated.

Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
