Introduction:
Knowledge of adverse events (AE) in acute care hospitals is a particularly relevant aspect of patient safety. Its incidence ranges from 3% to 17%, and surgery is related to the occurrence of 46%-65% of all AE.
Material And Methods:
An observational, descriptive, retrospective, multicenter study was conducted with the participation of 31 Spanish acute-care hospitals to determine and analyze AE in general surgery services.
Results:
The prevalence of AE was 31.53%. The most frequent types of AE were infectious (35%). Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. The majority of patients (58.42%) were attributed a category F event (temporary harm to the patient requiring initial or prolonged hospitalization); 14.69% of AE were considered severe, while 34.22% of AE were considered preventable.
Conclusions:
The prevalence of AE in General and GI Surgery (GGIS) patients is high. Most AE were infectious, and the most frequent AE was surgical site infection. Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. Most detected AE resulted in mild or moderate harm to the patients. About one-third of AE were preventable.
