Goal: Preventing confusion
The FDA has provided guidance for industry on naming drugs not yet approved so that the proposed names are not too similar in sound or appearance to those already on the market. Included in the lengthy document are checklists, such as, “Across a range of dialects, are the names consistently pronounced differently?” and “Are the lengths of the names dissimilar when scripted?” (Lengths are considered different if they differ by two or more letters.)
The FDA also offers the phonetic and orthographic computer analysis (POCA) program, a software tool that employs an advanced algorithm to evaluate similarities between two drug names. The data sources are updated regularly as new drugs are approved.
Liability update
The problem may be decreasing. In a 2020 report, researchers used pharmacists’ professional liability claim data from the Healthcare Providers Service Organization. They compared 2018 data on claims with 2013 data. The percentage of claims associated with wrong drug dispensing errors declined from 43.8% in 2013 to 36.8% in 2018. Wrong dose claims also declined, from 31.5% to 15.3%.
These researchers concluded that technology and automation have contributed to the prevention of medication errors caused by the use of the wrong drug and the wrong dose, but mistakes continue, owing to system and human errors.
