Objective - To develop and validate a set of practical prediction tools that reliably estimate the outcome of acute diquat poisoning（ADP）.~Design - Cohort study with logistic regression analysis to combine predictors and treatment modality.~Main outcome measure - The primary study outcome was death from any cause within 90 days after diquat ingestion.~Goals- To develop a prediction models that reliably estimates the outcome of patients who were managed in various settings for acute diquat poisoning.
Diquat (DQ) is a non-selective quick-acting bactericidal herbicide, which is the same bipyridine compound as paraquat (PQ).The number of patients with acute diquat poisoning is gradually increasing worldwide, and the mortality rate is not lower than that of paraquat (citing), but there is currently a lack of objective indicators to assess the severity or prognosis of diquat poisoning.By referring to SIPP ideas, the research team intends to establish a model that meets the clinical characteristics of diquat poisoning and effectively predicts the prognosis of patients, namely SIDP. In order to obtain an objective, accurate and relatively convenient method to judge the condition and prognosis of patients with acute diquat poisoning.
