To the Editor.
The article by Woods and colleagues1 cited previous work by Slonim et al2 regarding their use of external-cause-of-injury (E) codes in assessing pediatric patient safety events. Slonim et al did use administrative data and codes from the International Classification of Diseases, Ninth Revision (ICD-9), but nature-of-injury (N) codes were used, not E-codes as described by Woods et al. The difference between E-codes and N-codes is that an N-code describes the nature of an injury (laceration, contusion, etc). If an N-code is applied by a medical-records coder, it should be followed by a supplemental code, an E-code, which describes the mechanism of the injury (motor vehicle crash, adverse medical event, etc). This is according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) official guidelines for coding and reporting.3
Slonim et al used N-codes 995.2 and 996999, which indicate drug errors and complications of procedures and medical care. If E-codes with the same code numbers had been used (eg, E995E999), that would have indicated injuries resulting from operations of war.4
E-codes are routinely used by injury-control researchers for surveillance. E-codes useful in the detection of patient safety events include E870E876 (misadventures to patient during surgical and medical care), E878E879 (surgical and medical procedures as the cause of abnormal reaction of patients or later complication, without mention of misadventure at the time of procedure), and E930E949 (drugs, medicinal and biological substances causing adverse effects in therapeutic use).4
