Welcome to the APSA Quality and Safety Committee Venous Thromboembolism (VTE) Toolkit. This toolkit is intended to help anyone who is interested in quality improvement in the management of the patient with VTE.
Available toolkit projects are listed below. Many of the approaches described are evidence-based - some are not. These approaches have not been approved by APSA.
Venous Thromboembolism Guidelines for Pediatric Patients
Although VTE is rare in the pediatric population, several institutions have instituted clinical practices guidelines to assist with prophylactic management.
For instance, the Children’s Hospital of Richmond created a Venous Thromboembolism Risk Assessment Score (VTRAS) for patients ranging from 1-14 years of age, admitted for more than 23 hours, with the intent of guiding prophylactic therapy.

- Children’s Hospital of Richmond VTRAS Discussions During Scoring System Creation (10/2016)
Stakeholders: surgeons, residents, patients, nursing staff, intensivists, hematologists/oncologists, pediatricians
Challenges and solutions:
A subcommittee of the Pediatric Trauma Committee was convened and challenged with creating algorithms to manage children at risk for VTE. Monthly meetings were conducted for approximately a year in order to review the literature, define inclusion/exclusion criteria, develop a scoring sheet, educate the stakeholders and introduce the plan.
Initially, only paper forms could be utilized, and the logistics on where the blank forms were stored, and what to do with them once completed, became problematic. Therefore, usage was very low. Moreover, the form was initially used for patients between 12-14 years old, which made it difficult for residents to remember.
Currently, the form is available electronically (via the EMR) which automatically populates for all patients admitted for more than 24 hours.

St. Joseph’s Children’s Hospital in Tampa developed the BayCare Best Practice Guidelines which provides evidence-based criteria for VTE prophylaxis in patients 10-17 years old.
Brief project description:
VTE is one of the leading causes of hospital-acquired morbidity for children in the US. It significantly increases hospitalization costs and prolongs the length of stay. Therefore, it is important to identify risk factors for VTE in order to identify these hospitalized children at risk for hospital-acquired VTE (HA-VTE) and initiate timely prophylaxis.
An in-depth literature review of evidence-based practices, risk factors, and prevention for VTE in children was performed. A multidisciplinary team composed of physicians, pharmacy personnel, and nursing staff was created to develop guidelines that identified risk factors, created categories, and recommended prophylaxis for each category. The developed guidelines went through the proper approval bodies, including the Pediatric Trauma Service, St. Joseph’s Children’s Hospital Quality Council, and the Medical Executive Committee. It was subsequently adopted as a BayCare Best Practice Medical Standard.
Stakeholders: pharmacists, hematologists/oncologists, pediatric hospitalists, pediatric general surgeons, pediatric orthopedic surgeons, pediatric critical care physicians, evidence-based medicine specialists
Challenges and solutions:
- Identifying VTE risk factors- given the lack of standard pediatric VTE prophylaxis guidelines, different specialists had varying ideas on risk factors that should be included.
- Reviewed multiple published VTE risk assessment models and compared the risk factors identified within these models. Based on the evidence from these models, a list of VTE risk factors was developed for local use.

Venous Thromboembolism Guidelines for Pediatric Trauma Patients
Kentucky Children’s Hospital developed a clinical practice guideline for the use of VTE prophylaxis in pediatric trauma patients. It was developed by the Pediatric Interdepartmental Trauma Quality Assurance Committee, part of the ACS-verified Level I Pediatric Trauma Center.
Stakeholders: pediatric trauma patients (defined as < 16 years old), pediatric surgeons (subspecialties: general, neurosurgery, orthopedics), pediatric critical care physicians, nurses, pharmacists
Challenges and solutions:
VTE events are rare in pediatric trauma. The incidence of VTE is less than 1% in the general pediatric trauma population. Although rare, VTEs are potentially serious events. Pharmacologic prophylaxis against VTE is a reasonable strategy in critically injured adolescent trauma patients. The effectiveness of prophylaxis compared to its potential harms has not been proven in this population.

Tampa General Hospital, an ACS Level I trauma center, also developed a QI project in an attempt to protocolize and standardize VTE prophylaxis in injured pediatric patients, specifically for patients from 13-15 years of age.
Stakeholders: pediatric trauma team, orthopedic surgery, pediatric intensivists, pediatric hospitalists
Challenges and solutions:
The project was initiated due to significant variability regarding VTE prophylaxis in pediatric trauma patients with orthopedic injuries. The orthopedic surgeons had high variability in the manner and duration of VTE prophylaxis within their group. Additionally, the specifics of VTE prophylaxis would vary, month to month, with new resident teams. The push for guidelines came jointly from the trauma and medical teams, as there was always uncertainty regarding the specifics of the VTE prophylaxis. A review of the current data and literature regarding pediatric VTE was performed, as well as review of other hospitals’ pathways, in order to develop the local guidelines.
The initial versions dictated, more specifically, the mechanism for prophylaxis for each risk group. However, there was considerable pushback from the orthopedic surgeons which were adamant that, in addition to the medical and overall injury considerations, the variabilities in their operative techniques would require differing VTE prophylaxis. Several meetings with the orthopedic service were conducted, a firm consensus was not reached. The result is reflected in the final guideline stating that direct attending-to-attending discussions regarding VTE prophylaxis requirements would occur. This open-ended process was the only way the orthopedic service would sign off on the guidelines. In the end, a more uniform VTE prophylaxis was reached for low risk patients. There still remains a fair amount of variability in VTE prophylaxis in the higher risk patients with orthopedic injuries (particularly, femur and acetabular fractures) but less than during pre-guideline implementation. There has certainly been a decrease in resident to resident and resident to attending variability for VTE prophylaxis within the orthopedic service, as direct attending to attending discussions have improved communication between all the involved services.
