This editorial comments on the report by van der Togt and colleagues on electromagnetic interference (EMI) from radiofrequency identification (RFID) technologies affecting other medical equipment in intensive care units such as infusion pumps, external pacemakers, and mechanical ventilators. The investigators found 22 of 34 EMI incidents were hazardous. Berwick points out that another important lesson of the study is that physicians and other health care decision makers should tame technology, not avoid it.
