Abstract
Introduction: Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is the leading cause of preventable postoperative deaths. Identifying risk factors based on Virchow’s Triad (blood stasis, hypercoagulability, and endothelial injury) is crucial. Approximately 20% of surgical patients develop VTE, with 7% resulting in fatal PE. The Caprini risk score, used to assess VTE risk, is complex and has limited adherence despite its validation across various specialties. Methodology: The applied research developed the application of a perioperative protocol for VTE prophylaxis in the Vascular Surgery ward of the Hospital Municipal de Marabá. The descriptive and quantitative study was structured via website. The 2013 version of the Caprini score was adopted for risk stratification. Validation of the tool involved 16 experts with inclusion criteria focused on doctors and nurses with experience in the area, where everyone responded to the Likert scale that evaluated 2 major domains of the tool: usability and functionality. Results: Among the 16 evaluators, 56,3% were male and 43,8% female, with an average age of 32,4 years and 7,6 years of experience. The system’s functionality received 97,5% approval, 96,3% of reliability, and 91,3% regarding interface and usability. The utility was well-rated, with 98,8% approving the professional facilitation. Chi-square tests indicated that functionality perception did not vary between physicians and nurses, but utility was significantly influenced by profession. Cronbach’s alpha coefficients indicated high internal consistency: 0,85 for functionality and 0,77 for utility. Discussion: The diverse profiles of the evaluators enriched the website’s validation. Functionality was consistently positively rated, while utility varied by professional role. High internal consistency suggests that the questionnaire is reliable for measuring website performance perceptions. Conclusion: The inclusion of the Caprini protocol in the Tupan Health website demonstrated good performance and high reliability among professionals, facilitating protocol adherence and the prevention of perioperative complications.
