ARDI data are now included in the CDC Chronic Disease and Health Promotion Open Data Site. This site allows you to create filtered datasets and customize visualizations, as well as quickly access a wide range of chronic disease data, risk factor indicators, and policy measures.

One of the ICD-10 sub-codes for Alcoholic Liver Disease (K70.0) was incorrectly denoted in the SAS code that was used to analyze death data for the Alcohol-Related Disease Impact (ARDI) application. As a result, from 2006 to 2010, 331 average annual deaths due to Alcoholic Liver Disease with an underlying cause of death coded as K70.0 were inadvertently excluded from the calculation of total deaths due to this condition. This error has been corrected, resulting in a slight increase in the estimated average annual alcohol-attributable deaths (AAD) and years of potential life lost (YPLL) for these conditions in the U.S. and in states.

December 12, 2013:

The Alcohol-Related Disease Impact (ARDI) application has been updated to provide average annual estimates of alcohol-attributable deaths (AAD) and years of potential life lost (YPLL) for the United States and for states for 2006-2010. ARDI also includes new estimates of AAD and YPLL for all 54 conditions that are assessed in the application, including all chronic (e.g., alcoholic liver disease) and acute (e.g., alcohol-attributable motor-vehicle traffic crashes) conditions.

The indexing procedure, which is used in the ARDI application to assure that self-reported information on binge drinking episodes is included in the calculation of average daily alcohol consumption, has also been updated. Specifically, instead of using a national estimate of binge drinking intensity (i.e., the number of drinks consumed per binge drinking episode), the indexing procedure used in ARDI now uses state-specific estimates of binge drinking intensity based on the average largest number of drinks consumed reported by binge drinkers in state Behavioral Risk Factor Surveillance System (BRFSS) surveys. The use of these state-specific estimates of binge drinking intensity in the ARDI application will improve the accuracy of state estimates of average daily alcohol consumption and thus the accuracy of state-specific estimates of AAD and YPLL as well.

 

July 25, 2012:

2005 life expectancy data has been added to ARDI, resulting in new life expectancy averages for all ages by sex for 2001-2005. Previous life expectancy average included average for 2001-2004. This update resulted in a slight change to the estimated years of potential life lost (YPLL) overall and by state.

To calculate years of potential life lost (YPLL), the alcohol-attributable fractions (AAF) for a specific cause of death are multiplied by the number of deaths in a given category and then multiplied by the average number of years of life remaining based on life expectancy of the decedent. Data on life expectancy are obtained from the National Vital Statistics System managed by the National Center for Health Statistics. Life expectancy data are stratified by age and sex using standard 5-year age groupings.

October 13, 2011:
The average grams of alcohol per drink − which is used in ARDI to convert the average number of grams of alcohol consumed per day, as specified in some of the meta-analyses used to obtain risk estimates, into the average number of drinks per day – was changed from 13.7 grams per drink to 14.0 grams per drink, consistent with current recommendations from the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The prevalence of drinking at the new average daily alcohol consumption levels (e.g., low, medium, and high average daily alcohol consumption, as defined by the meta-analyses used in ARDI) was then assessed using national and state-specific data from the Behavioral Risk Factor Surveillance System (BRFSS).

This change in the number of grams of alcohol per drink – and, in turn, in the prevalence of drinking at specified alcohol consumption levels − has slightly changed the estimated number of alcohol-attributable deaths (AAD) and years of potential life lost (YPLL) for the U.S. and for states that are reported in the ARDI application.

ARDI gets a makeover: The redesigned Alcohol-Related Disease Impact (ARDI) application was launched today. The estimates in the application have not changed.

The Alcohol-Related Disease Impact (ARDI) online application allows users to access national and state estimates of alcohol-related health impacts, including deaths and years of potential life lost (YPLL), for 54 acute and chronic causes using alcohol-attributable fractions, by age and sex. ARDI was recently upgraded to a more user-friendly platform.
