Bleeding and Bruising: Primary Care Evaluation.

Area of Science:

• Internal Medicine
• Hematology

Background:

• Easy bruising and bleeding are common patient complaints in primary care settings.
• Accurate diagnosis is essential for appropriate patient management and treatment.

Purpose of the Study:

• To outline a systematic approach for evaluating patients with abnormal bleeding and bruising in primary care.
• To highlight key diagnostic tools and laboratory tests for identifying bleeding disorders.

Main Methods:

• Utilizing a bleeding assessment tool combined with comprehensive history and physical examination.
• Incorporating patient-provided photographs to aid in visual assessment.
• Performing initial laboratory tests including complete blood cell count, peripheral blood smear, prothrombin time (PT), international normalized ratio, activated partial thromboplastin time (aPTT), and fibrinogen.

Main Results:

• Normal PT and aPTT results may suggest a platelet disorder.
• A normal PT with a prolonged aPTT indicates an intrinsic coagulation pathway disorder.
• A prolonged PT with a normal aPTT suggests an extrinsic coagulation pathway disorder.

Conclusions:

• A structured approach including history, physical exam, and targeted laboratory testing can effectively identify causes of abnormal bleeding.
• Consideration of nonaccidental trauma is important, particularly in vulnerable populations.
• Hematology consultation is recommended for persistent concerns or confirmed bleeding disorders.
