Abstract
Background
Venous thromboembolism (VTE) is a critical complication of varicose vein
treatments. The Caprini Score (CS) is an established tool to assess
patients’ VTE risks. One disadvantage is the number of questions required,
some of them referring to a low incidence of disease, even lower in patients
seeking an elective procedure. These elements take time and may result in
filling errors if the CS is not filled out by a properly trained health
professional.
Objective
To establish a response pattern in CS, with emphasis on questions that
usually have a negative answer and propose a simpler adaptative digital
version without changing the original structure of the tool.
Methods
two hundred and twenty-seven patients in the pre-surgical treatment of
varicose veins were enrolled prospectively and submitted to the CS
evaluation.
Results
The pattern of dichotomous responses could be divided arbitrarily into four
subgroups considering the percentage of positive responses: none (11 items),
less than 3% (13 items), between 3% and 20% (5 items), and more than 20% (8
items). Of the 12 CS questions related to illnesses that occurred in the
last month, ten had had no responses, and 2 were less than 3%.
Conclusion
There is a pattern in the CS responses of patients with an indication of
surgical treatment of varicose veins. Many of the CS questions are not
helpful in this scenario and may result in filling errors performed by
untrained providers. An adaptative version of the CS might benefit varicose
