Insights

This retrospective drug utilization review found that thrombolysis for myocardial infarction (MI) largely followed hospital guidelines. However, some patients did not receive treatment due to atypical presentation, with slightly higher mortality in untreated cases.

Area of Science:

  • Cardiology
  • Pharmacology
  • Health Services Research

Background:

  • Retrospective drug utilization review (DUR) assesses adherence to clinical trial recommendations in practice.
  • Evaluating adherence to hospital guidelines for thrombolysis in myocardial infarction (MI) is crucial for patient care.

Purpose of the Study:

  • To assess whether thrombolysis administration for myocardial infarction (MI) aligned with established hospital protocols.
  • To identify reasons for non-administration of thrombolytic therapy in MI patients.

Main Methods:

  • A retrospective drug utilization review (DUR) was conducted.
  • Data from patients diagnosed with myocardial infarction (MI) admitted to Borders General Hospital between April and December 1993 were analyzed.

Main Results:

  • 48% of patients received thrombolysis (52% of definite MI cases).
  • Atypical presentation, particularly ECG findings inconsistent with guidelines, was the primary reason for withholding thrombolysis.
  • Mortality rates at discharge and 6 months were slightly higher in patients who did not receive thrombolytic therapy.

Conclusions:

  • Thrombolytic drug use generally adhered to hospital guidelines for MI treatment.
  • In two instances, the use of alteplase over streptokinase lacked clear justification.
  • Appropriate reasons existed for all cases where thrombolytic therapy was not administered.

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...

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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

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...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

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.
