Adverse drug events in hospitalized cardiac patients

Area of Science:

• Cardiology
• Pharmacovigilance
• Patient Safety

Background:

• Limited data exists on adverse drug events (ADEs) in cardiac patient populations.
• Adverse drug events represent a significant concern in hospitalized patients, particularly those with cardiovascular conditions.

Purpose of the Study:

• To analyze the incidence and characteristics of ADEs in cardiac patients.
• To identify patterns and risk factors associated with ADEs in this demographic.
• To inform strategies for reducing ADEs in cardiac care.

Main Methods:

• A retrospective review of all reported adverse drug reactions and medication errors in cardiac patients over a 5-year period.
• Data analysis focused on event types, drug classes, contributing factors, and patient outcomes.
• Surveillance program data from Brigham and Women's Hospital was utilized.

Main Results:

• A total of 547 ADEs were identified in cardiac patients, representing a rate of 1.9 events per 100 admissions.
• Medication administration errors were the most frequent cause (34.2%), specifically incorrect medication rates or frequencies.
• Cardiovascular agents, anticoagulants, and antimicrobials were the most common drug classes involved; 5.3% of patients experienced injury or prolonged hospitalization.

Conclusions:

• Adverse drug events are common in hospitalized cardiac patients, affecting approximately 2 out of every 100 admissions.
• The high incidence of ADEs during medication administration necessitates increased focus and resources on this critical step.
• Targeting interventions around nursing shift changes may effectively enhance preventive strategies for ADEs in cardiac care.
