Background: Patient awareness of venous thromboembolism (VTE) and thromboprophylaxis is essential for their safety. In this study, we evaluated patients' awareness of VTE and their perceptions of thromboprophylaxis.
Methods: We administered a cross-sectional survey to patients hospitalized at the King Abdulaziz Medical City, Riyadh, Saudi Arabia.
Results: Of 190 patients approached, 174 completed the survey, constituting a response rate of 95%. Most participants (72%) were receiving thromboprophylaxis. However, only 32 and 15% reported knowledge of deep vein thrombosis (DVT) and pulmonary embolism (PE), respectively. Fifty-five percent of participants with knowledge of DVT identified swelling of the leg as a symptom. Risk factors for blood clot development were correctly identified by about half of participants, although most agreed that blood clots can cause death (77%). The level of awareness of DVT or PE did not significantly differ by respondents' demographics. However, awareness of DVT or PE was significantly higher among those with a personal or family history of VTE. Participants had positive perceptions of thromboprophylaxis and were satisfied with treatment (> 69%), but perceived its adverse effects less favorably and reported lower satisfaction with the information provided about DVT and PE (46%).
Conclusion: This study demonstrates the lack of awareness of VTE, DVT, and PE among hospitalized patients. More attention must be paid to patient education to ensure safe and high-quality patient care.
