Objective:

To evaluate the clinical effectiveness of a specialized thrombosis service (TS) on patients diagnosed with acute venous thromboembolism (VTE) compared to usual care (UC), emphasizing the comparative aspect.

Key Findings:

• The TS demonstrated high patient satisfaction (85%) and strong adherence to prescribed anticoagulation therapy (88%) during its first 2 years, with a focus on clinical outcomes.
• The study aimed to assess whether the advantages of the TS in care processes translate into improved clinical outcomes for patients with acute VTE.

Interpretation:

The study seeks to determine the impact of a multidisciplinary approach on clinical outcomes for VTE management, addressing gaps in existing care models and highlighting the importance of the findings.

Limitations:

• Cause-specific mortality could not be evaluated due to lack of cause of death data, which limits the study's comprehensiveness.
• Cancer status was not available, limiting adjustment for malignancy-associated mortality, which could affect outcome interpretation.
• Medication dispensing records were inconsistently aligned with diagnosis dates, affecting reliability of anticoagulant data.
• Outpatient follow-up visits were only available as fee-for-service counts, preventing comparison of follow-up intensity.

Conclusion:

A rigorous evaluation of the TS model is necessary to ascertain its effectiveness in improving clinical outcomes for patients with acute VTE, emphasizing its potential impact on patient care.
