Adverse events associated with antimicrobial compounds in a general hospital in Chile
ABSTRACT Background: Antimicrobial compounds are associated with a wide range of adverse events (AE) and some of them can be potentially preventable. Aim: To characterize AE associated with antimicrobial compounds. Patients and Methods: Retrospective analysis of AEs reported to the National Pharmacological Surveillance System from 2014 to 2017 in a regional hospital. Severity, causality and preventability were analyzed. Results: Sixty events were observed in 56 patients aged 2 months to 96 years. Cases were registered mostly in hospitalized patients. The most frequent AEs were skin disorders (56.7%), followed by hepatobiliary (13.3%), and CNS events (10%). Blood, kidney, respiratory gastrointestinal and immunological disorders were less frequently registered, including cases with anaphylactic shock and Stevens-Johnson syndrome (SJS). Causal analysis indicated a definitive association in 8.3%, probable in 70% and possible in 22%. Skin lesions were mostly associated with beta-lactams, hepatobiliary disorders with antituberculosis drugs and CNS manifestations with carbapenems. Cutaneous, neurological, and hepatobiliary events appeared at a median of 4, 2.5 and 10.5 days after starting the medication, respectively. AEs were managed with withdrawal of the suspected drug (83.3%) and other auxiliary therapies. AEs were categorized as severe in 22% and one case with SJS had a fatal outcome (1.7%). Preventability analysis revealed 25% of potentially avoidable events. Conclusions: Antimicrobial AE involved a wide diversity of compounds, occurred in different hospitalization units, affected patients of a wide age range and attacked different systems or organs. An important fraction was potentially avoidable.
