Insights

The risk of vascular thromboembolic events after hospital discharge for Coronavirus disease 2019 (COVID-19) is low. Routine post-discharge thromboprophylaxis is not recommended for these patients.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Pulmonology

Background:

  • Hospitalized patients with Coronavirus disease 2019 (COVID-19) face elevated risks of thromboembolic events.
  • The persistence of this thromboembolic risk following hospital discharge requires further investigation.

Purpose of the Study:

  • To determine the incidence of vascular thromboembolic events within 30 days of discharge in outpatients recently hospitalized for COVID-19.
  • To identify potential risk factors, such as intensive care unit admission, advanced age, and anticoagulation status, associated with these post-discharge events.

Main Methods:

  • A retrospective cohort study was conducted.
  • The study included 447 outpatients recently discharged after hospitalization for COVID-19.

Main Results:

  • A low incidence of 2.0% for vascular thromboembolic events was observed within 30 days post-discharge.
  • No specific risk factor, including intensive care admission, age, or anticoagulation, was significantly linked to an increased risk of these events.

Conclusions:

  • The incidence of vascular thromboembolic events after COVID-19 hospital discharge is low.
  • Findings do not support the routine use of post-discharge thromboprophylaxis for COVID-19 patients.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Disorders of Hemostasis01:24

Disorders of Hemostasis

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.
