Common blood disorders: a primary care approach

Area of Science:

• Hematology
• Geriatrics
• Internal Medicine

Background:

• Anemias and blood-forming element diseases are increasingly prevalent in aging populations.
• Iron deficiency is the leading cause of anemia, often linked to occult blood loss.
• Other common anemias manageable in primary care include vitamin B12 and folate deficiencies, and drug- or autoimmune-induced hemolytic anemias.

Purpose of the Study:

• To review common anemias and blood disorders in older adults.
• To differentiate conditions manageable by primary care physicians from those requiring specialist referral.
• To highlight diagnostic approaches for refractory anemias and platelet disorders.

Main Methods:

• Literature review of anemias and blood disorders in the geriatric population.
• Discussion of primary care management strategies for common anemias.
• Overview of specialist-indicated conditions and diagnostic tools like bone marrow aspiration.

Main Results:

• Iron deficiency anemia is highly prevalent and often associated with undetected blood loss.
• Vitamin B12, folate deficiencies, and certain hemolytic anemias are responsive to primary care interventions.
• Nonresponsive anemias, hematologic malignancies, and drug-induced platelet disorders are common in older adults and necessitate specialist evaluation.

Conclusions:

• Primary care physicians can effectively manage several types of anemia in older patients.
• Hematologic malignancies and refractory anemias in the elderly typically require specialized hematologic expertise.
• Bone marrow aspiration is a key diagnostic tool for refractory anemias and certain platelet disorders.
