[Characteristics of 972 poisoning inpatients].

Objective: To analyze the clinical characteristics of poisoning inpatients in the first affiliated hospital of chongqing medical and pharmaceutied hospital, and to provide basis for improving the level of prevention, control, diagnosis and treatment of regional poisoning. Methods: In January 2024, using the HIS medical record system of The First Affiliated Hospital of Chongqing Medical and Pharmeceutical College, we collected the clinical data of poisoning inpatients admitted to our hospital from 2018 to 2023. The data of sex, age, time of poisoning, poison species, poisoning cause, poisoning route, season, treatment and prognosis were analyzed. Results: A total of 972 patients were enrolled, among whom 71.71% (697/972) were young and middle-aged adults, with a higher incidence in summer. Chemical poisoning accounted for 53.61% (521/972) , followed by pesticide poisoning and mixed poisoning in the second and third places. The overall detection rate of toxins was 58.23% (566/972) . The number of domestic poisonings increased year by year, while occupational poisonings decreased year by year, with statistically significant differences (P<0.05) . The overall cure and improvement rate was 97.22% (945/972) , and the cure and improvement rate of pesticide poisoning was the lowest at 90.23% (120/133) . Factors such as age >60 years, intentional exposure to toxins, pesticide exposure, gastric lavage, blood purification, and length of hospital stay affected the prognosis of patients (P<0.05) . Conclusion: Health education should be actively promoted, toxin control should be strengthened, scientific and reasonable prevention and control measures as well as treatment methods should be adopted to reduce the incidence and mortality of poisoning.
