NHDS – Injury Summary

Medical information about discharges includes up to seven diagnoses and up to four surgical and nonsurgical operations and procedures. Medical data are coded to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). Basic demographic information is also included for patients discharged. Medical cost information is not collected in this survey.

Injury data can be analyzed using principal or first-listed diagnosis codes or all diagnosis codes listed. The State and Territorial Injury Prevention Directors Association (STIPDA) has developed Consensus Recommendations for Using Hospital Discharge Data for Injury Surveillance [PDF – 150 KB].
