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.
