Incidence of Symptomatic Venous Thromboembolism (VTE) in 8,885 Elective Total Hip Arthroplasty Patients Receiving Post-operative Aspirin VTE Prophylaxis

Association Between Venous Thromboembolism Prophylaxis and the Incidence of Thromboembolism Following Orthopedic Procedures: A Cross-Sectional Study

INTRODUCTION

Venous thromboembolism (VTE) is a significant concern following orthopedic procedures, necessitating effective prophylactic measures. The rates of VTE prophylaxis, however, vary widely between institutions and nations, falling between 13% and 70% on average. In the absence of adequate thromboprophylaxis, pulmonary embolism, which accounts for 5% to 10% of mortality in hospitalized patients, is one of the leading causes of death. This study investigates the relationship between VTE prophylaxis and thromboembolism incidence, considering patient characteristics, risk assessment completion, anticoagulant prescription, and weight-bearing status.

OBJECTIVES

To evaluate the knowledge gap by examining the relationship between VTE prevention and the prevalence of thromboembolism also to examine the anticoagulant prescription trends for patients being discharged from orthopedic operations and to investigate the connection between post-procedure weight-bearing status and the development of VTE problems.

METHODOLOGY

A retrospective, cross-sectional design was employed, analyzing 200 orthopedic procedure patients from January to June of 2023 performed at Rehman Medical Institute. After getting ethical approval from the institutional ethical approval board, data were collected on the basis of variables encompassing patient attributes, surgery details, VTE risk factors, prophylaxis type, and VTE complications. Data was entered and analyzed via IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States), and the data were run through various tests including descriptive statistics, cross-tabulations, and chi-square. Results were then presented in the form of a table.

RESULTS

Among 200 individuals 24 individuals experienced VTE, while 176 did not. Significant gender-based VTE differences were observed (p = 0.01). Hypertension (HTN) showed a significant association (p = 0.04) with VTE. Major surgeries were correlated with higher VTE incidence (p = 0.03). Pharmacological prophylaxis reduced the occurrence of VTE (p = 0.01). Early mobilization and Ted stockings were correlated with lower VTE incidence (p = 0.04, p = 0.12).

CONCLUSION

This study reveals gender-specific VTE differences, emphasizes the role of HTN, surgical nature, and prophylaxis in VTE incidence, and supports tailored prophylactic strategies. Our findings align with previous research and emphasize the significance of tailored prophylaxis strategies. By examining multiple factors, including gender, co-morbidities, surgical characteristics, and prophylactic methods, our study contributes to the evidence base that supports clinical decision-making and enhances patient safety in orthopedic surgery.
