English abstract
Objectives: To evaluate the prevalence of risk for venous thromboembolism (VTE) and
the proportion of at-risk patients who receive appropriate thromboprophylaxis among
inpatients in acute hospital care settings in Oman. A related objective was to evaluate
the type and time of initiation of VTE prophylaxis. Methods: This multicenter, crosssectional study was conducted in three tertiary hospitals in Oman. The study included
acutely ill medical and surgical inpatients admitted from August to September 2022.
VTE risk assessment and prophylaxis were assessed based on the 2012 recommendations
of the American College of Chest Physicians (ACCP). Results: A total of 384 patients
were enrolled, 240 were medical patients and 144 were surgical patients. As per the
ACCP criteria, 179 (74.6%) of medical and 92 (63.9%) of surgical patients were at risk
for VTE and required prophylaxis. Appropriate prophylaxis was received by 142 (79.3%)
at-risk medical and 70 (76.1%) at-risk surgical patients. In cases where pharmacological
prophylaxis was contraindicated, mechanical prophylaxis was markedly underused.
For medical patients, the median day of initiating VTE prophylaxis was day one of
admission. For surgical patients, the median day of initiating VTE prophylaxis was
postoperative day one. Conclusions: The majority of hospitalized patients in Oman
are at risk of VTE. However, a significant minority of patients do not receive the required
pharmacological or mechanical prophylaxis. We recommend the development of a
national VTE risk assessment and guiding tool with a facility for monitoring compliance.
