2. INTRODUCTION
Deep vein thrombosis (DVT) occurs when a blood clot forms in the deep veins,
usually in the leg. As many as 900,000 people could be affected (1 to 2 per 1,000)
each year in the United States. Estimates suggest that 60,000-100,000 Americans
die of DVT/PE (also called venous thromboembolism). (CDC, 2022).
Timely risk identification leads to timely implementation of prophylactic
measures leading to higher chance of treatment success and prevention of
morbidity and mortality.
QPS GOAL
Implement an evidence-based protocol for DVT prevention (supported by CDS).

3. CDS TOOL DESCRIPTION
CDS Aim & Description
VTE risk assessment and prophylaxis order set can assist clinicians to accurately
stratify patients according to known risk factors and administer the right
prophylaxis measure based on the best available evidence-based guideline.
Knowledge base guiding the CDS
Recommendations based on locally adapted national guidelines were used in the
development of the VTE risk assessment and prophylaxis order set.

for Healthcare Research and Quality; August 2016. AHRQ Publication No. 16-0001-EF.

4. CDS TOOL DESCRIPTION
Benefits of the CDS system
It eliminates the risk of alert fatigue by use of an admission order set.
Potential flaw of the CDS system
The impact of CDS on DVT and bleeding episodes after hospital discharge
was not considered.
Improvement Suggestion
CDS design should be modified to include adherence checks at alternate
points in the users’ workflow I.e., pharmacists and nurses.

6. CONCLUSION
How CDS can help achieve the QPS goal
VTE risk assessment and prophylaxis order set is to assist clinicians to
accurately stratify patients according to known risk factors and administer the
right prophylaxis measure based on the best available evidence-based
guideline.
This ensures that all eligible patients receive care appropriate to them.
This DVT risk assessment protocol can help the healthcare provider to prevent
DVT incidence by providing a structured DVT prevention order set based on
Current evidence. This promotes adherence to standard of care.
