Incidence and factors associated with deep vein thrombosis among hospitalized adult patients at Hawassa university comprehensive specialized hospital Hawassa city, Sidama, Ethiopia: retrospective cohort study.

Abstract

Deep vein thrombosis is a public health problem with substantial morbidity and mortality globally. In Ethiopia, death due to complications of DVT is very significant however its incidence, risk factors, and preventive methods are not well studied. To assess the incidence and factors associated with deep vein thrombosis among hospitalized adult patients at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia. Intuitional-based retrospective study design was employed in July1-August 30, 2022 in 660 randomly selected patients' record cards. The patients' record cards were reviewed from 2012 to 2014 at Hawassa University Compressive Specialized Hospital. The data entry and analysis were done by using Epi Info and SPSS version 24. After adjusting covariates at a 95% confidence interval, an independent variable with a P value < 0.05 was declared significantly associated with deep vein thrombosis. An odds ratio was calculated to measure the strength of the relationship independent variable and deep vein thrombosis. The overall incidence of DVT was 10.6% [95% CI: 8.5%, 13.1%]. After adjusting for covariates, orthopedic trauma; AOR = 2.6 (95% CI (1.2-5.4), corona virus; AOR = 2.5 (95%CI (1.07-5.1), and hospital stay > 15days; AOR = 2.2 (95% CI (1.25-3.94) were significantly associated with deep vein thrombosis. DVT incidence is high among hospitalized patients. An orthopedic trauma, a recent infection of the coronavirus, and a hospital stay above 15days were a risk to acquire deep vein thrombosis. Early identification and detection of patients at high risk of developing DVT and provision of prophylaxis are recommended.
