Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

563
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

689
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Disorders of Hemostasis01:24

Disorders of Hemostasis

881
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Summary

Venous thromboembolism (VTE) testing in trauma patients did not differ by prophylaxis. However, race, injury severity, and socioeconomic status influenced VTE surveillance patterns.

Area of Science:

  • Orthopaedic Surgery
  • Trauma Care
  • Vascular Medicine

Background:

  • Venous thromboembolism (VTE) is a significant risk for trauma patients.
  • Optimal VTE surveillance strategies in this population are still being investigated.

Purpose of the Study:

  • To analyze VTE testing patterns in orthopaedic trauma patients.
  • To compare VTE surveillance rates based on different prophylaxis regimens.
  • To identify patient factors associated with VTE testing.

Main Methods:

  • Secondary analysis of the ADAPT trial, a prospective randomized trial.
  • Inclusion of 329 adult trauma patients with specific fracture types requiring VTE prophylaxis.
  • VTE imaging studies within 90 days post-injury were recorded.

Main Results:

  • Only 20.4% of patients underwent VTE testing; 29.9% of those tested were positive.
  • No significant difference in VTE testing rates between aspirin and low-molecular-weight heparin (LMWH) prophylaxis groups (P=0.50).
  • White race, higher Injury Severity Score, and lower socioeconomic status (higher Area Deprivation Index) were linked to increased VTE testing.

Conclusions:

  • VTE surveillance practices in orthopaedic trauma patients are not significantly influenced by the prophylaxis regimen used.
  • Patient demographic and socioeconomic factors play a role in determining who receives VTE surveillance.
  • Further research may be needed to standardize VTE testing protocols in trauma care.
