Tools and Frameworks

 

Tools for Categorizing International Classification of Diseases (ICD) Codes 

• 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 Framework for Presenting Injury Mortality Data - External Cause
  The ICD-9 External Cause Matrix emphasizes the mechanism or cause of the injury and places secondary emphasis on the manner or intent of the injury.
• 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.
  • SAS Input Statements for External Cause of Injury Morbidity Matrix
• ICD-10 Framework for Injury Mortality Diagnosis Matrix
  The ICD-10 Injury Mortality Diagnosis (IMD) matrix is a framework designed to organize injury diagnosis mortality data into meaningful groupings by body region and nature of injury.
• ICD-10 Framework for Presenting Injury Mortality Data - External Cause
  The ICD-10 External Cause Matrix emphasizes the mechanism or cause of the injury and places secondary emphasis on the manner or intent of the injury. The ICD-10 injury mortality framework was developed to be as consistent as possible with the recommended framework developed based on the ICD-9 external cause of injury codes.

Classifications

• International Classification of Diseases Home Page
  • International Classification of Diseases, Ninth Revision (ICD-9)
  • International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)
  • International Classification of Diseases, Tenth Revision (ICD-10)
  • International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM)
  • Classification of Death and Injury from Terrorism
  • International Classification of Functioning, Disability and Health (ICF)
• International Classification of External Causes of Injury (ICECI)
  The International Classification of External Causes of Injury (ICECI) is based on best practices of injury surveillance and on international consensus about how external causes may be described.

NCHS Datasets

 

National Hospital Ambulatory Medical Care Survey (NHAMCS), Emergency Department Visit Data

• SAS Statements for External Cause of Injury Matrix: SAS statements for assigning external cause of injury codes to mechanism and intent of injury based on the ICD-9-CM external cause of injury matrix in NHAMCS-ED.
• SAS Statements for Identifying Injury Records: SAS statements for selecting 1st listed injury diagnosis and 1st listed E-code for defining an injury record in NHAMCS-ED
• STATA Programs for Identifying Injury Records: STATA program for selecting 1st listed injury diagnosis and 1st listed E-code for defining an injury record in NHAMCS-ED.
• SAS and SUDAAN Programs for Variance Estimation: Sample SAS and SUDAAN codes and documentation for variance estimation of complete NHAMCS-ED data.
• Example of a SAS Program for Obtaining Frequencies of Injury Visit in NHAMCS-ED: Sample SAS and SUDAAN programs that create weighted frequency counts for injury visit by age and gender and export to Excel file. You will need to modify the program to get the weighted frequencies for desired subpopulation, year, and age groups.
