Adverse drug events (ADEs), such as drug-related bleeding (DRB), represent a serious public health issue and highlight the role of triggers in pharmacovigilance. This study aimed to identify the triggers used to detect inpatient DRB. A systematic review was conducted and registered in PROSPERO (CRD42023440337). The search included the databases PubMed, LILACS, Cochrane Library, Embase, and Web of Science, covering published studies on ADEs in hospitalized adults focused on DRB triggers, with no language restrictions, up to September 2024. Methodological quality was assessed using the Joanna Briggs Institute tool, and trigger performance was evaluated by Positive Predictive Value (PPV). Twenty-three studies were included, identifying 28 triggers for DRB with PPV ranging from 0% to 100%. Prolonged INR and PTT were the most high-performing laboratory triggers, while textual triggers have demonstrated their potential, despite requiring adjustments to avoid false positives. A multimodal approach of laboratory and textual triggers combined emerges as beneficial to ADEs surveillance. Standardized and rigorous methodologies are recommended to strengthen evidence and guide clinical interventions.
