Abstract

INTRODUCTION: The incidence of pediatric hospital-acquired venous thromboembolism (HA-VTE) has increased over time. Congenital heart disease (CHD) as a co-morbidity has been demonstrated to significantly increase HA-VTE risk among hospitalized children.

OBJECTIVE: To identify specific risks factors for the development of HA-VTE in hospitalized children with CHD.

MATERIALS AND METHODS: This retrospective case-control study included hospitalized participants aged 0-21 years within the Children's Hospital Acquired Thrombosis (CHAT) Consortium Registry with a co-morbidity of CHD. Participants with HA-VTE and non-VTE controls with a past medical history of CHD were selected from the CHAT Registry and data regarding multiple clinical variables were extracted. These variables were then analyzed to assess their association with HA-VTE development.

RESULTS: Three hundred and thirty-three participants with a co-morbidity of CHD were identified, comprising 275 HA-VTE cases and 58 controls. Median age for HA-VTE cases was 0.4 (IQR = 0-2.6) years compared to 3.4 (IQR = 0.7-6.5) for controls. Male participants were predominant in both groups (57.5 % HA-VTE cases vs 51.7 % controls). Multivariable analysis identified prior recent hospitalization (OR = 4.12, 95%CI = 1.66-10.24), intensive care unit (ICU) admission (OR = 3.29, 95 % CI = 1.15-9.40), and CVC placement (OR = 9.14, 95 % CI = 3.38-24.72) as significant risk factors for HA-VTE in subjects with CHD.

CONCLUSIONS: ICU admission, CVC placement, and prior hospitalization were identified as statistically significant predictors associated with HA-VTE development in hospitalized children with history of CHD. Prospective studies are needed to validate these results and help develop strategies to mitigate HA-VTE development in these patients.
