Insights

Patients with atrial fibrillation (AF) taking oral anticoagulants (OACs) show knowledge gaps, particularly those on direct-acting oral anticoagulants (DOACs). Improving patient education on anticoagulation therapy is crucial for better treatment outcomes.

Area of Science:

  • Cardiology
  • Pharmacology
  • Patient Education

Background:

  • Atrial fibrillation (AF) is a common arrhythmia with significant health and economic impacts.
  • Anticoagulants are vital for preventing stroke and systemic embolism in AF patients.
  • Patient knowledge of anticoagulation therapy influences treatment efficacy and outcomes.

Purpose of the Study:

  • To assess anticoagulation knowledge levels in AF patients using oral anticoagulants (OACs).
  • To identify patient-related factors associated with OAC knowledge.
  • To compare knowledge between warfarin and direct-acting oral anticoagulant (DOAC) users.

Main Methods:

  • An online survey was administered to recruit participants.
  • Validated tools, including the Anticoagulation Knowledge Tool, were used.
  • Patient-related factors and medication adherence were assessed.

Main Results:

  • Warfarin users demonstrated higher anticoagulation knowledge scores than DOAC users (73% ± 13% vs. 66% ± 14%).
  • Key predictors of knowledge included age, OAC type, health information overload, and perceived ease of use.
  • Beliefs about bleeding side effects differed significantly between warfarin and DOAC groups.

Conclusions:

  • Significant knowledge gaps exist in AF patients on OACs, with DOAC users showing greater deficiencies.
  • Integrating knowledge assessments into patient counseling is recommended to address deficits.
  • Enhanced patient education can improve understanding and adherence to anticoagulation therapy.

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Introduction to Surveying, Plane Surveying and Geodetic Surveys

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Errors and Mistakes in Surveying01:19

Errors and Mistakes in Surveying

Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...
