Analysis of Clinical Characteristics of Adverse Drug Reactions Reported in a Three-A General Hospital from 2020 to 2022
Objective:To analyze the clinical characteristics of adverse drug reactions(ADRs)reported in the hospital from 2020 to 2022,and provide reference for the clinical safe medication for patients.Methods:The ADR reports of 1 971 cases reported to China National Center for ADR Monitoring by the First Affiliated Hospital of Soochow University from January 2020 to December 2022 were selected as research data.The information such as patient age,clinical manifestations of ADRs and involved organs,as well as types,dosage forms,and administration methods of drugs involved in ADRs was collected to analyze the clinical characteristics of ADRs.Results:In the ADR reports of 1 971 cases,the age of patients was mainly 40 years old or above(1 643 cases,83.36%).In the three years,the dosage form of drugs involved in ADRs was mainly injection,followed by tablets;the main route of administration was intravenous drip,followed by oral administration;the top 10 drugs involved in ADRs were mainly iodixanol injections,warfarin sodium tablets and anti-tumor drugs,and the reported number of ADRs induced by anti-tumor drugs showed an increasing trend year by year.Among the ADR reports of 1 971 cases,the report type was mainly"general"(1 442 cases,73.16%),but the reports of"serious"type involved 529 cases(26.84%);the involved organs and systems of serious ADRs(529 cases)mainly included the immune system(136 cases,25.71%),digestive system(113 cases,21.36%),skin and its appendages(93 cases,18.58%)and circulatory system(93 cases,18.58%).The main consequences of serious ADRs included"leading to hospitalization or prolonged hospitalization"(268 cases,50.66%)and"leading to other important medical events"(223 cases,42.16%),but there were 35 cases(6.62%)that endangered patients'lives.Conclusion:The middle-aged and elderly individuals are the high-risk group for ADRs,and the incidence of serious ADRs is relatively high.Therefore,it is required to continuously strengthen the medication education and monitoring in clinical practice to ensure that patients can be treated as soon as possible once ADRs occur and guarantee their safe medication.
