Prediction tool for thrombi associated with peripherally inserted central catheters

Area of Science:

• Medical research
• Vascular medicine
• Patient safety

Background:

• Increasing incidence of upper extremity deep vein thrombosis (UEDVT) associated with peripherally inserted central catheters (PICCs).
• Limited understanding of risk factors for UEDVT compared to lower extremity deep vein thrombosis.
• Need for effective prophylaxis strategies in at-risk patient populations.

Purpose of the Study:

• To identify patients at highest risk for developing upper extremity deep vein thrombosis.
• To develop a predictive tool for upper extremity deep vein thrombosis to guide prophylactic measures.
• To improve patient outcomes by mitigating risks associated with central venous catheterization.

Main Methods:

• Retrospective review of medical records for patients with peripherally inserted central catheters over a 6-month period.
• Analysis of patient data to identify potential risk factors for upper extremity deep vein thrombosis.
• Development and validation of a weighted risk factor measure, the upper extremity deep vein thrombosis prediction tool.

Main Results:

• A total of 233 patient records were reviewed, with 17 (7.3%) cases of upper extremity deep vein thrombosis identified.
• The developed upper extremity deep vein thrombosis prediction tool demonstrated high sensitivity (88%) and specificity (82%).
• The tool achieved a high negative predictive value (99%) and correctly classified 82% of cases, though positive predictive value was lower (28%).

Conclusions:

• The developed upper extremity deep vein thrombosis prediction tool shows promise in identifying patients at high risk.
• Further validation on a larger patient sample is recommended to confirm the instrument's efficacy.
• The tool can potentially aid in initiating timely and effective prophylaxis for upper extremity deep vein thrombosis.
