Venous Thrombosis I: Introduction

831
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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

470
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...

Venous Thrombosis III: Interprofessional Care

482
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 IV: Nursing Management

418
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. Review medication intake, particularly oral contraceptives,...

Area of Science:

  • Medical informatics
  • Clinical prediction modeling
  • Machine learning in healthcare

Background:

  • Deep venous thrombosis (DVT) is a serious condition, often affecting hospitalized patients, with potential for fatal pulmonary embolism.
  • Early detection and intervention are critical for managing DVT risk, especially in immobile or post-surgical patients.
  • Existing prediction methods may not adequately capture the complexity of DVT risk factors.

Purpose of the Study:

  • To evaluate and compare the performance of eight machine learning models in predicting deep venous thrombosis risk.
  • To identify the most effective machine learning model for early DVT detection in a clinical setting.
  • To assess the clinical utility of machine learning for improving patient outcomes by preventing DVT complications.

Main Methods:

  • Eight machine learning models were assessed: logistic regression, random forest, XGBoost, artificial neural networks, k-nearest neighbors, gradient boosting, CatBoost, and LightGBM.
  • Model performance was rigorously evaluated using metrics such as accuracy, precision, recall, F1-score, specificity, and ROC curve analysis.
  • The study focused on predicting DVT risk in hospitalized patient populations.

Main Results:

  • Logistic regression demonstrated superior performance, achieving high accuracy and an excellent receiver operating characteristic (ROC) curve score.
  • The logistic regression model exhibited high recall, effectively identifying a significant majority of true deep venous thrombosis cases.
  • While other models like random forest and XGBoost showed competitive results, logistic regression proved most reliable across all evaluated metrics.

Conclusions:

  • Machine learning models, particularly logistic regression, show significant potential for the early detection of deep venous thrombosis.
  • The high performance of logistic regression suggests its value in clinical decision support for DVT risk assessment.
  • Implementing advanced predictive models can lead to timely interventions, ultimately improving patient outcomes and reducing DVT-related mortality.
