Brief summary: Venous thromboembolism (VTE) is common especially among post-operative patients, and its occurrence is associated with significant morbidity and mortality. VTE is highly preventable with prophylactic modalities ranging from conservative measures such as early mobilization, to mechanical prophylaxis such as intermittent pneumatic compression (ICP), to pharmacological prophylaxis such as peri-operative anticoagulation. Despite established guidelines from various professional societies, the practice of VTE prophylaxis varied greatly from institute to institute. Evidence suggests that there is a significant gap between the optimal thromboprophylaxis as suggested by experts and real-work practice. Many healthcare-providers (HCP) and patients at risk of VTE are either not aware of the risk of VTE or not confident to apply the necessary thromboprophylaxis. The knowledge level of VTE appears to play a key role in affecting the level of compliance to the optimal thromboprophylaxis. Considerable improvement in VTE prophylaxis utilization may result from the implementation of a multifaceted educational program. By improving patient's awareness on VTE prophylaxis, the incidence of DVT might be reduced. The knowledge level of patients can be improved by various means including educational video, administrative measures, or continue medical education program. However, no prospective study has been performed to assess the impact of an educational program on the VTE knowledge level among post-operative patients and their HCP, and if any improvement of their knowledge level can be translated to a better adherence to VTE prophylaxis guidelines. We therefore propose to conduct a prospective non-randomized controlled study to evaluate the effect of an education materials for the patients as well as their HCP on their knowledge level as well as the utilization and adherence of VTE prophylaxis in these patients by comparing two groups of patients and HCP.
