Hospital-acquired thrombocytopenia

Area of Science:

• Internal Medicine
• Hematology

Background:

• Thrombocytopenia is a frequent complication in hospitalized patients, significantly increasing mortality risk.
• Common causes include underlying illnesses (infection, DIC) and iatrogenic factors (drug reactions, HIT, surgery).

Purpose of the Study:

• To review the pathophysiology, clinical features, and management of hospital-acquired thrombocytopenia.
• To provide a diagnostic framework for clinicians to identify and manage various causes of low platelet counts in inpatients.

Main Methods:

• Literature review focusing on common etiologies of hospital-acquired thrombocytopenia.
• Discussion of diagnostic criteria including platelet count fall, bleeding/thrombosis, clinical context, and blood smear analysis.

Main Results:

• Identified key etiologies: infection, DIC, drug-induced immune thrombocytopenia, heparin-induced thrombocytopenia, posttransfusion purpura, hemodilution, surgery, and extracorporeal circuits.
• Proposed a diagnostic approach integrating clinical and laboratory findings.

Conclusions:

• Effective management of hospital-acquired thrombocytopenia requires accurate diagnosis based on clinical context and specific etiology.
• A structured diagnostic approach aids clinicians in differentiating causes and optimizing patient care.
