Abstract

Objective:

Venous thromboembolism (VTE) has become a huge health problem as well as a financial burden for the National Health Service. The objective of this study was to characterize current practice of VTE prophylaxis (VTEP) and evaluate the economic impact of clinical pharmacists' interventions (CPIs) on VTEP.

Methods:

A prospective service evaluation was conducted in a medical and surgical ward at a tertiary teaching hospital in London from 23 May to 08 June 2016. Appropriateness of risk assessment (RA) and VTEP and CPIs were categorized and assessed. Based on the results of the service evaluation, a pharmacoeconomic analysis was undertaken to estimate the cost savings by CPIs for inappropriate pharmacological VTEP.

Findings:

A total of 203 cases were analyzed. The rates of appropriateness for RA on admission, RA at 24 h and pharmacological VTEP were 58.6%, 39.7%, and 75.4%, respectively. In the medical ward, there was a significant difference of appropriate RAs between on admission and at 24 h (70.3% vs. 23.8%, respectively). Whereas, the rate of appropriate pharmacological VTEP accounted for 75.4% and the rate of appropriate prophylaxis was significantly higher in the medical ward than surgical ward (80.5% vs. 68.2%, P = 0.045). Of 50 cases of inappropriate pharmacological prophylaxis, 39 cases (78.0%) were corrected by clinical pharmacists. These CPIs resulted in £1,286.23 cost savings during the study and it was estimated to be £517,522/annum.

Conclusion:

CPIs had significant positive clinical and economic impacts on VTEP. There is more scope for the improvement of RA at 24 h through CPIs.

Venous Thrombosis III: Interprofessional Care

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 IV: Nursing Management

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

Pharmacovigilance

Pharmacovigilance

Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

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...

Pulmonary Embolism III: Nursing Management

Pulmonary Embolism III: Nursing Management

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...

Clinical Trials

Clinical Trials

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...
