Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

16
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

19
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,...

Pulmonary Embolism III: Nursing Management01:27

Pulmonary Embolism III: Nursing Management

25
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

24
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...

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

613
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

24
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Area of Science:

  • Healthcare Informatics
  • Clinical Decision Support Systems
  • Patient Safety

Background:

  • Venous thromboembolism (VTE) is a significant cause of morbidity and mortality.
  • Effective VTE prophylaxis requires accurate risk assessment and timely intervention.
  • Electronic health record (EHR) systems can facilitate VTE risk assessment and prophylaxis but require user-friendly design.

Purpose of the Study:

  • To evaluate the usability of a new VTE clinical decision support system (CDSS) among healthcare providers.
  • To identify areas for improvement in the CDSS's risk assessment model and prophylaxis ordering components.
  • To assess provider perceptions and facilitate the adoption and usage of the VTE CDSS.

Main Methods:

  • A laboratory usability testing study was conducted with 24 healthcare providers.
  • Participants completed two case scenarios using the VTE CDSS, engaging in think-aloud sessions.
  • Post-task interviews and the System Usability Scale (SUS) were administered to collect feedback.

Main Results:

  • The VTE CDSS achieved an average SUS score of 72.39 (C grade).
  • Key themes from provider feedback included personalization of workflow, minimizing clicks, clarity of risk models, and integration of treatment guidelines.
  • Participants provided actionable insights regarding functionality, visibility, navigation, and content.

Conclusions:

  • Usability testing identified critical areas for optimizing the VTE CDSS to enhance provider experience.
  • Implementing user-driven improvements is essential for increasing provider adoption and retention of the VTE CDSS.
  • User-friendly tools are vital for quality healthcare delivery and preventing VTE events.
