Venous Thromboembolism (VTE) remains the number one preventable cause of death in hospitalized patients resulting in approximately 300,000 deaths per year in the United States alone. One of the leading causes of death can be due to a blood clot, also known as Venous Thromboembolism (VTE) that can lead to a Pulmonary Embolism (PE). Studies have shown that being on blood thinners can reduce this risk however, there can be repercussions with prescribing any patient a blood thinner. Therefore, studies have been done to prescribe appropriate medication for this condition.


In 2020, the Usability Lab helped created an IMPROVE-DD calculator that is able to assess the risk of a an admitted patient developing a blood clot. This tool allows clinicians to add the patient information into the calculator and  provides them a calculation a score between 0-100% of them developing a blot clot during their stay and provides a pop-up alert so the clinician can prescribe the patient blood thinners if needed. The tool serves as an aid to assist the physician in making their decision during the assessment of the patient. This serves as a method of prophylactic treatment option.  It will present the opportunity for providers to order VTE prophylaxis (pharmacologic and mechanical) as a direct result of this risk assessment. Phase I was usability testing of the tool with hospitalists who currently work in the environment where the tool was going to be implemented. We used the think-aloud method and recorded their audio and screen-shared to observe workflow. Once all the information was captured, it was coded and categorized. The feedback and comments are given consideration before the tool went live within our inpatient EMR called Sunrise Clinical Manager.(SCM)


The calculator tool has been successfully implemented with an increasing number of uses per week indicating that clinicians have adopted the calculator within their daily workflow because it has proven to be useful in avoiding a thrombobolic event from occurring.


For quite some time, physicians have hesitated to prescribe blood thinners because of the risk associated with it. However, with their own clinical experience and aid from the assessment calculator physicians are more likely to lean towards taking a prophylactic approach and prescribing medications with ease.
