Data Source

National Hospital Discharge Survey (NHDS)

NHDS - 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. State and Territorial Injury Prevention Directors Association (STIPDA) has recommended methods of analysis for injury hospital discharges. Information on the external cause of injury should be coded from the medical record. In 2001 only 68 percent of injury discharges had an external cause of injury code.

Tools and Frameworks

Barell Matrix

The Barell Matrix is a two-dimensional array of three-, four-, and five-digit ICD-9-CM injury codes grouped by the body region of the injury and the nature of the injury and was developed by the International Collaborative Effort on Injury Statistics

ICD-9-CM Framework for Presenting Injury Morbidity Data-External Cause

This matrix contains the ICD-9-CM external cause of injury codes that are not included in ICD-9 mortality codes. In addition, a list of codes that have been added since 1994 is appended to the matrix.
