Venous thromboembolism prophylaxis usage among surgical patients in both private and public hospitals in Ethiopia

Venous thromboembolism (VTE) remains the commonest preventable cause of death in postoperative patients. VTE prophylaxis significantly reduces mortality risk, yet its utilization remains alarmingly low and variable (6-61 %) worldwide. This study aimed to compare VTE prophylaxis use among adult surgical patients in major hospitals in Addis Ababa, Ethiopia.

A multicenter cross-sectional study was conducted in one private (Myungsung Christian Medical Center Comprehensive Specialized Hospital (MCM CSH)), and two public hospitals (Yekatit 12 Hospital Medical College and Menelik II Referral Hospital). Data was collected by chart review using standardized checklist. Caprini score was used for risk stratification, and associations was assessed using chi-square test with significance set at p < 0.05.

From a total of 423 patients, 222 (52.3 %) patients were male. The mean age of the patients is 43.3(±14.7 SD) years. 414 (98 %) patients were at risk for VTE with 257(61 %) having moderate to high risk, but only 31(7.5 %) were on prophylaxis. Prophylaxis use was 12.5 % in MCM CSH, but it was 5.5 % and 5.1 % in Yekatit 12 and Menelik II Referral Hospitals respectively. VTE prophylaxis use was significantly less in public hospitals (p < 0.05).

Despite the majority of surgical patients being at risk of developing VTE, VTE prophylaxis remains significantly underutilized across major private and public hospitals in Ethiopia, particularly in public settings. The current study suggests standard risk assessment model implementation to address this significant and understudied risk to patients' lives.
