Which international classification of disease (ICD) revision was used to report the data?
ICD-9 and ICD-10 are both still used when classifying mortality data. This international classification provides for a means of comparison between the US and other countries. ICD-10 is more detailed than ICD-9 and utilizes an alpha-numeric system; ICD-9 was a numeric only system. For the purpose of comparison, see Anderson, RN, et al. (2001). Comparability of Cause of Death Between ICD-9 and ICD-10: Preliminary Estimates. National Vital Statistics Reports, 49(2). The World Health Organization has posted ICD-10 codes online. C. Is the mortality data measuring underlying cause of death or multiple causes of death? Some Healthy People data (specifically diabetes) reports using multiple causes; mortality data via many of the sources on these pages show underlying cause only. Be certain you know which you are looking at so you aren’t mislead by conflicting data. 3. What is the unit of measure of the data? As you look at the data, be sure you understand what the actual unit of measure is. Ar
