After a cautious and rigorous analysis of national malpractice claims, Johns Hopkins patient safety researchers estimate that a surgeon in the United States leaves a foreign object such as a sponge or a towel inside a patient’s body after an operation 39 times a week, performs the wrong procedure on a patient 20 times a week and operates on the wrong body site 20 times a week.
The researchers, reporting online in the journal Surgery, say they estimate that 80,000 of these so-called "never events" occurred in American hospitals between 1990 and 2010 - and believe their estimates are likely on the low side.
The findings - the first of their kind, it is believed - quantify the national rate of "never events," occurrences for which there is universal professional agreement that they should never happen during surgery. Documenting the magnitude of the problem, the researchers say, is an important step in developing better systems to ensure never events live up to their name.
