Popis: Background: Paraquat poisoning remains a critical public health issue with no established effective treatment. Hemoperfusion (HP) has been recognized for its potential to remove toxins and is widely employed in several developing countries for managing acute paraquat poisoning cases. However, the reluctance of some patients to undergo this recommended treatment has been observed but not thoroughly investigated. This study aimed to explore the factors associated with the refusal of HP in patients suffering from paraquat intoxication. Materials and Methods: In this retrospective study, data of 358 patients with acute paraquat poisoning were analyzed in Xi’an, China. The outcome of our study was mortality, and the influential factors were age, gender, marital status, educational level, symptoms at presentation, and laboratory findings. A logistic regression model was utilized to explore the independent risk factors. Results: In a total of 358 paraquat-poisoned patients, the significant differences were found between patients who underwent HP and those who did not, particularly regarding mean age (48.02 years vs. 42.32 years; P = 0.01), mental disorders (15.6% vs. 6.1%; P = 0.01), poisoning severity score (2.36 vs. 2.57; P = 0.03), organ failure (10.9% vs. 23.5%; P = 0.02), and mechanical ventilation (18.8% vs. 33.3%; P = 0.02). Patients who refused HP exhibited a higher mortality (20.3% vs. 10.9%; P = 0.03) compared to those who received HP. Age (odds ratio (OR), 1.76; 95% confidence interval (CI): 1.01–3.82; P = 0.01) and history of mental disorders (OR, 2.81; 95% CI: 1.19-6.61; P = 0.02) were identified as significant independent predictors for the refusal of HP. Conclusion: The results of this study showed that elderly individuals and those with a history of mental disorders were independently associated with refusing HP in patients with acute paraquat poisoning.
