Abstract: Objective To investigate the occurrence and outcomes of drug-induced liver injury in hospitalized patients and provide evidence for rational drug use in the clinic. Methods Drug-induced liver injury (DILI) reported between January 1, 2014 and July 31, 2022 was analyzed retrospectively. Cases of DILI adverse reactions were screened by setting inclusion and exclusion criteria before they were analyzed in terms of age, gender, clinical typing, RUCAM scores severity, regression, and drugs involved. Results A total of 201 268 hospitalizations were collected, and 448 inpatients with DILI adverse reactions were screened. The incidence of DILI adverse reactions was 0.22%. The male-to-female ratio was 1: 0.56. The mean age was (59.24±18.22) years old, and there was a significant difference between males and females in age (P< 0.05). The diseases were mostly infectious diseases (28.35%) and cerebrovascular diseases (27.46%), and the clinical manifestations were primarily non-specific. As for clinical types, the dominating type was hepatocyte injury (218 cases, 48.46%), followed by the mixed type (161 cases, 35.93%), and the cholestasis type (69 cases,15.40%). The RUCAM scale score averaged above 3 points, with 264 cases (58.93%) ≥6 points. There were significant differences in RUCAM scores and severity between the three clinical types. The levels of ALT, AST, ALP, GGT, TBIL and ALB were also significantly different between. The top three suspected types of drugs were cardio-cerebrovascular and lipid-regulating drugs, antibiotics and antipyretic analgesics. The top three suspected drugs were atorvastatin, rosuvastatin and moxifloxacin. There were 387 cases (86.38%) of mild liver injury according to the grading of severity. There were of 36 cases of moderate liver injury (8.04%), compared with 25 cases of severe liver injury (5.58%). The clinical outcomes were generally good after drug withdrawal/reduction and liver-protecting and symptomatic treatment. Conclusion Male, middle-aged and elderly patients are prone to DILI adverse reactions, especially mild to moderate liver injury. Clinical use of cardio-cerebrovascular and lipid-regulating drugs, antibiotics, antipyretic analgesics requires alertness to DILI adverse reactions.
