Insights
Implementation of venous thromboembolism prevention guidelines in Croatian hospitals was insufficient. Few high-risk patients received thromboprophylaxis, with no significant change after guideline introduction.
Area of Science:
- Medical Practice
- Clinical Guidelines
- Thromboprophylaxis
Background:
- Venous thromboembolism (VTE) is a significant clinical concern.
- Evidence-based guidelines aim to improve VTE prevention.
- The 9th edition of American College of Chest Physicians (ACCP9) guidelines provide recommendations for VTE prophylaxis.
Purpose of the Study:
- To evaluate the clinical implementation of ACCP9 guidelines for VTE prevention in nonsurgical patients.
- To assess thromboprophylaxis rates before and after guideline implementation in two Croatian hospitals.
Main Methods:
- Retrospective analysis of medical charts for 850 nonsurgical patients across two hospitals.
- Data collected from periods before and after ACCP9 guideline dissemination.
- Comparison of thromboprophylaxis rates between hospitals and time periods.
Main Results:
- No statistically significant difference in thromboprophylaxis rates for high-risk patients post-guideline implementation.
- Dubrava University Hospital consistently had higher thromboprophylaxis rates than Zadar General Hospital.
- Overall implementation of evidence-based thromboprophylaxis guidelines was found to be insufficient.
Conclusions:
- The ACCP9 guidelines for VTE prevention were inadequately implemented in the studied Croatian hospitals.
- Further strategies are needed to improve adherence to evidence-based thromboprophylaxis protocols.
- Hospital-specific factors may influence guideline adoption and patient care outcomes.
Abstract:
The aim of this study was to evaluate the implementation of the 9th edition of the American College of Chest Physicians (ACCP9) guidelines for prevention of venous thromboembolism in nonsurgical patients in clinical practice in one university and one general Croatian hospital. A retrospective study was conducted at Zadar General Hospital from Zadar and Dubrava University Hospital from Zagreb. Medical charts of all patients admitted to Medical Departments in two periods, before and after implementation of the ACCP9 guidelines, were analyzed. The ACCP9 guidelines were made available to all physicians through the hospital electronic information system immediately after the publication. The Hospital Drug Committees promoted implementation of the guidelines during their periodical clinical visits. Overall, 850 patients were included in the study in two periods. There was no statistically significant difference in the number of high-risk patients receiving thromboprophylaxis after the guidelines implementation in either hospital. In both periods, a signifi-cantly higher number of high-risk patients received thromboprophylaxis in Dubrava University Hos-pital in comparison with Zadar General Hospital (31.7% vs. 3.8% and 40.3% vs. 7.3%, respectively; p<0.001). This study revealed insufficient implementation of evidence-based thromboprophylaxis guidelines in clinical practice in two Croatian hospitals.
