Routine preoperative coagulation testing is outdated and not evidence-based. Current guidelines recommend patient history over routine screening to identify bleeding risks before surgery.
Area of Science:
- Anesthesiology
- Hematology
- Surgical Care
Background:
- Coagulation testing is a traditional preoperative assessment.
- The aim is to identify patients at risk of perioperative bleeding due to bleeding disorders.
- Low prevalence of bleeding disorders and healthcare system implications are concerns.
Purpose of the Study:
- To review the current evidence on preoperative coagulation testing.
- To provide a comprehensive view of its relevance in modern surgical practice.
Main Methods:
- Literature review of existing studies and guidelines.
- Analysis of the evidence supporting or refuting routine preoperative coagulation screens.
Main Results:
- Evidence suggests routine coagulation screening is not evidence-based.
- Current guidelines advocate against routine testing.
- Emphasis is shifting towards thorough patient bleeding history.
Conclusions:
- Routine preoperative coagulation testing is considered outdated.
- Personal and family bleeding history is recommended to guide further investigations.
- This approach optimizes patient care and resource utilization.
