Medical Systems That First Do No Harm
Everyone makes mistakes, especially when it comesto entering numbers into a calculator orspreadsheet. It’s not such a big deal if you’re tracking how much you spend on pizza. But ifyou’re administering drugs in a hospital, such a slip can be deadly. Now a report in the Journalof the Royal Society Interface [see Harold Thimbleby and Paul Cairns, http://bit.ly/cqcD83] shows how devices can be programmed to catch at least some mistakes on the spot.
Dosing a patient with 10 times too much medication is disturbingly common. One studysuggests this error occurs in 1 percent of all hospital admissions. And though the personpunching in the numbers is at fault, most drug–delivery devices don’t help.
In one machine, for example, mistakenly entering a number with two decimal points—like 1.2.3—might be read by the machine as 1.23, or as a 123. To prevent such wild guessing, scientists tested a system that immediately flags any input that’s not a real number. Accordingto their analysis, that safeguard alone could cut factor–of-10 errors in half.
Charles Darwin once noted that “to kill an error is as good a service as…establishing a new truthor fact.” Even more so when killing the error keeps you from killing a patient.
