BACKGROUND: Prior studies have not examined national trends and characteristics of unintentional non-health care facility (HCF) medication errors associated with cardiovascular drugs.
OBJECTIVE: To investigate non-HCF medication errors associated with cardiovascular drugs reported to poison control centers in the United States.
METHODS: A retrospective analysis of non-HCF medication errors associated with cardiovascular drugs from 2000 to 2012 was conducted using the National Poison Data System database.
RESULTS: There were 278 444 medication errors associated with cardiovascular drugs reported to US poison control centers during the study period, averaging 21 419 exposures annually. The overall rate of cardiovascular medication errors per 100 000 population increased 104.6% from 2000 to 2012 ( P < 0.001) and the highest rates were among older adults. Most cases (83.6%) did not require treatment at a HCF. Serious medical outcomes were reported in 4.0% of exposures. The cardiovascular drugs most commonly implicated in medication errors were β-blockers (28.2%), calcium antagonists (17.7%), and angiotensin-converting enzyme inhibitors (15.9%). Most of the 114 deaths were associated with cardiac glycosides (47.4%) or calcium antagonists (29.8%). Most medication errors involved taking or being given a medication twice (52.6%).
CONCLUSIONS: This study describes characteristics and trends of non-HCF cardiovascular medication errors over a 13-year period in the United States. The number and rate of cardiovascular medication errors increased steadily from 2000 to 2012, with the highest error rates among older adults. Further research is needed to identify prevention strategies for these errors, with a particular focus on the older adult population.
