Abstract
Background: Postoperative pulmonary embolism (PPE) is a critical complication that can significantly affect patient outcomes. This study aimed to assess knowledge, attitudes, and practices (KAP) of thoracic healthcare professionals toward PPE. Methods: A cross-sectional study was conducted from September to December 2022. Results: A total of 222 thoracic healthcare professionals participated in the study; the majority were aged 30-40 years (40.54%) and had over 10 years of work experience (47.75%). Participants completed a self-designed questionnaire assessing demographic data and KAP scores: knowledge (0-11), attitudes (11-55), and practices (9-45). The main measures included the mean scores for knowledge, attitudes, and practices, along with correlation analyses and path analysis to assess relationships among the KAP components. Mean scores were 9.03 ± 1.13 for knowledge, 50.09 ± 4.23 for attitudes, and 35.78 ± 7.85 for practices. Participants showed strong awareness of PPE definitions and risk factors, but only 24.77% correctly identified its classic clinical triad. Attitudinally, while most expressed a willingness to engage in PPE training and risk assessment, 55.41% remained cautious about anticoagulation due to bleeding risks. In practice, although 72.52% consistently supported postoperative mobilization, only 30.63% frequently acquired updated PPE knowledge. Significant positive correlations were found between knowledge and attitudes (r = 0.218, p < 0.001) and between attitudes and practices (r = 0.234, p < 0.001). Path analysis showed that knowledge positively influenced attitudes (path coefficient 0.748, p = 0.002), and attitudes positively influenced practices (path coefficient 0.374, p = 0.003). Conclusions: Thoracic healthcare professionals exhibited adequate knowledge, positive attitudes, and proactive practices regarding PPE, indicating a strong foundation for enhancing postoperative care.
