Study Identifies Medications Most Involved in ER Visits
/By Pat Anson, PNN Editor
Here’s a question for you: What type of medication is most likely to be involved in a visit to a hospital emergency room?
Opioid pain relievers
Blood thinners
Psychiatric drugs
Insulin
Antibiotics
Given the well-publicized risks of addiction and overdose associated with opioids, you might assume it was opioid pain relievers. You’d also be wrong, according to a large new study that looked at medications associated with emergency department (ED) visits in the U.S. from 2017 to 2019.
CDC researchers looked at a representative sample of nearly 97,000 cases of adverse events involving medication and found that warfarin (Coumadin) and other anti-coagulant blood thinners – typically prescribed to reduce the risk of heart attack and stroke -- were the leading cause of ED visits.
Among patients of all ages, insulin was the second leading cause of medication-related adverse events, followed by psychiatric drugs, antibiotics and the over-the-counter pain relievers ibuprofen and acetaminophen. The opioid oxycodone came in last on a Top 10 list of drugs involved in ED visits.

The study findings, published in JAMA, help dispel many of the myths associated with the risks of opioids — at least in comparison to other widely used medications.
There are many reasons for someone to have an adverse reaction to medication, ranging from allergies to dosage errors to taking drugs intended for someone else. About a third of the ED visits were so serious, the patient was admitted for hospitalization.
Compared to seniors age 65 and older, young adults were significantly more likely to abuse a medication or to use it for intentional self-harm. Seniors were far more likely to only take a drug for its intended therapeutics use.

The age of a patient also plays a significant role in the type of drug they have an adverse reaction to. For example, the antibiotic amoxicillin was the leading cause of medication harm for patients under the age of 14; while the anti-anxiety drug alprazolam (Xanax) was the leading cause of adverse events for patients aged 15 to 44. Insulin ranked first for patients aged 45-64; while warfarin was first for patients aged 65 and older.
Analgesics, sedatives and antidepressants were the drugs most likely to be abused. About 63% of adverse events involving prescription opioids were cases of “non-therapeutic” abuse, while 89% of cases involving benzodiazepines were classified as abuse. The vast majority of cases involving blood thinners, insulin or antibiotics were for their intended therapeutic use.
The role of opioids in ED visits has been falling for over a decade. A 2017 study showed a significant decline in the number of patients admitted to U.S. hospitals for abusing opioid medication. Hospital admissions for overdoses from opioid medication started falling in 2010, the same year that opioid prescriptions peaked in the U.S.
