Measurement of the awareness of venous thromboembolism in the Saudi population

BACKGROUND: Venous thromboembolism (VTE) causes significant morbidity and mortality. International studies have suggested poor public awareness of VTE, with a few data from Saudi Arabia. The aim of this study was to investigate the knowledge and awareness of VTE in the Saudi population. Awareness of other important diseases was also investigated to allow contextualization. METHODS: A cross-sectional survey study was conducted throughout Saudi Arabia from April to June 2021. A nonprobability, purposive, social media-driven, snowballing sampling technique was used to distribute a validated online questionnaire to Saudi adults (aged over 18 years) from the general population. RESULTS: Of 1226 respondents, 214 were excluded as they were health-care professionals. The majority of the participants were unaware and unconcerned about VTE. They were more aware of other medical conditions such as hypertension. Immobility and old age were frequently recognized as risk factors for VTE. While less than half of the participants were aware that thrombosis is the cause of VTE, most participants correctly identified leg pain and tenderness as symptoms of deep venous thrombosis. The majority of the participants identified chest pain and breathlessness as symptoms of pulmonary embolism. However, leg paralysis and slow, shallow breathing were frequently identified as symptoms of VTE. The majority of subjects disagreed with the statement, “having a blood clot is not considered a medical emergency.“ Awareness of VTE varied significantly with age. CONCLUSION: In Saudi Arabia, the public awareness of VTE is poor. To improve outcomes, public health initiatives must increase awareness, introduce preventive measures, encourage early diagnosis, and ensure compliance with treatment.
