Insights
Pediatric patients undergoing surgery have a 0.20% risk of venous thromboembolism (VTE), with higher rates in cardiothoracic and general surgery. Unique risk factors identified can help predict and prevent VTE in this population.
Area of Science:
- Pediatric Surgery
- Vascular Surgery
- Epidemiology
Background:
- Venous thromboembolism (VTE) is a significant concern in adult surgical patients.
- Understanding VTE incidence and risk factors in pediatric surgical populations is crucial for targeted prevention strategies.
Purpose of the Study:
- To evaluate the incidence of VTE in patients undergoing inpatient pediatric surgery.
- To identify demographic and perioperative risk factors associated with VTE development post-pediatric surgery.
Main Methods:
- Analysis of 153,220 inpatient pediatric surgical cases from the 2012-2015 NSQIP-P database.
- VTE occurrence within 30 days of surgery was the primary outcome.
- Logistic regression and Kaplan-Meier survival analysis were used to generate prediction models and assess outcomes.
Main Results:
- A total of 305 patients (0.20%) developed VTE, with a median time to event of 9 days.
- Cardiothoracic (0.72%) and general surgery (0.28%) subspecialties showed the highest VTE rates.
- Independent predictors of VTE included higher American Society of Anesthesiologists (ASA) class, preoperative sepsis, ventilator dependence, enteral/parenteral feeding, steroid use, blood transfusion, gastrointestinal disease, hematologic disorders, operative time, and age.
Conclusions:
- Pediatric postsurgical patients exhibit distinct risk factors for VTE.
- Identifying these unique risk factors is essential for developing effective VTE prevention protocols in pediatric surgical care.
Purpose:
To evaluate venous thromboembolism (VTE) rates and risk factors following inpatient pediatric surgery.
Methods:
153,220 inpatient pediatric surgical patients were selected from the 2012-2015 NSQIP-P database. Demographic and perioperative variables were documented. Primary outcome was VTE requiring treatment within 30 postoperative days. Secondary outcomes included length of stay (LOS) and 30-day mortality. Prediction models were generated using logistic regression. Mortality and time to VTE were assessed using Kaplan-Meier survival analysis.
Results:
305 patients (0.20%) developed 296 venous thromboses and 12 pulmonary emboli (3 cooccurrences). Median time to VTE was 9 days. Most VTEs (81%) occurred predischarge. Subspecialties with highest VTE rates were cardiothoracic (0.72%) and general surgery (0.28%). No differences were seen for elective vs. urgent/emergent procedures (p = 0.106). All-cause mortality VTE patients was 1.2% vs. 0.2% in patients without VTE (p < 0.001). After stratifying by American Society of Anesthesiologists (ASA) class, no mortality differences remained when ASA < 3. Preoperative, postoperative, and total LOSs were longer for patients with VTE (p < 0.001 for each). ASA ≥ 3, preoperative sepsis, ventilator dependence, enteral/parenteral feeding, steroid use, preoperative blood transfusion, gastrointestinal disease, hematologic disorders, operative time, and age were independent predictors (C-statistic = 0.83).
Conclusions:
Pediatric postsurgical patients have unique risk factors for developing VTE.
Level Of Evidence:
Level II.
