Global Trigger Tool: Proficient Adverse Drug Reaction Autodetection Method in Critical Care Patient Units

Area of Science:

• Pharmacovigilance
• Clinical Quality Improvement
• Emergency Medicine

Background:

• Adverse drug reactions (ADRs) are frequently undetected in emergency departments (EDs).
• Trigger tools, effective for retrospective surveillance, were evaluated for prospective application.
• This study aimed to refine trigger tool utility in real-time healthcare settings.

Purpose of the Study:

• To determine the prevalence of ADRs in an ED setting.
• To prospectively assess the effectiveness of trigger tools in detecting ADRs.
• To enhance patient safety through improved ADR identification.

Main Methods:

• A prospective study utilizing the Institute for Healthcare Improvement (IHI) trigger tool methodology was conducted in an ED.
• 51 trigger tools were applied to analyze 463 patient records for ADRs.
• Statistical analysis was performed to evaluate trigger significance and ADR association.

Main Results:

• ADRs were detected in 13.39% of patients, with 75.8% classified as probable and 24.2% as possible by WHO-UMC criteria.
• Common triggers included abrupt medication stoppage (34.98%) and antiemetic use (25.91%).
• Significant positive predictive values were observed for triggers like INR > 4, vitamin K administration, steroid use, and rash. Five or more triggers indicated a statistically significant chance of ADR development (p < 0.05).

Conclusions:

• Trigger tools present a viable method for identifying ADRs, potentially surpassing traditional detection approaches.
• Further research is needed to validate the IHI tool's efficacy in general outpatient settings.
• Enhanced trigger tools could significantly aid healthcare providers in detecting ADRs and improving patient care.
