Adverse Drug Event
Any harm a patient experiences from a medication, whether from a side effect, error, allergic reaction, or overdose. Tracking adverse drug events is central to medication safety and quality monitoring.
What is an Adverse Drug Event?
An Adverse Drug Event is any injury or harm a patient suffers as a result of taking a medication. The harm can stem from a known side effect, an allergic or idiosyncratic reaction, an incorrect dose, or a mistake somewhere in the prescribing, dispensing, or administration process.
Not every adverse drug event reflects an error, and not every medication error causes harm. The defining feature is that the patient experiences actual harm connected to a drug, which is why these events are recorded separately from near misses and prescribing errors that are caught in time.
Why does tracking Adverse Drug Events matter?
Adverse drug events are among the most common preventable causes of patient harm, so measuring and analyzing them is a cornerstone of medication safety programs. Patterns in the data help organizations identify high-risk drugs, weak handoffs, and process gaps that can be fixed before another patient is hurt.
In a surgery center, anesthetics, opioids, anticoagulants, and reversal agents are used in quick succession around a procedure, and patients are discharged the same day. Catching and documenting adverse drug events supports both immediate clinical response and the quality reporting that regulators and accreditors expect.
