Urban-rural Differences in Unintentional Injury Death Rates Among Children Aged 0-17 Years: United States, 2018-2019.

Unintentional injuries are the leading cause of death among children aged 0-17 years (1). In 2018-2019, 14% of children in the United States aged 0-17 years resided in rural areas but accounted 24% of all childhood injury deaths (1). Urban-rural differences in injury mortality have been associated with a variety of factors, including differences in types of activities, use of safety equipment, practice of safety-related behaviors, built environments, and access to care (2-9).

A Revised ICD-10-CM Surveillance Case Definition for Injury-related Emergency Department Visits.

Background-Administrative data from medical claims are often used for injury surveillance. Effective October 1, 2015, hospitals covered by the Health Insurance Portability and Accountability Act were required to use the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) to report medical information in administrative data. In 2017, the National Center for Health Statistics (NCHS) and the National Center for Injury Prevention and Control (NCIPC) published a proposed ICD-10-CM surveillance case definition for injuryrelated emergency department (ED) visits.

Unintentional Drowning Deaths Among Children Aged 0-17 Years: United States, 1999-2019.

Drowning deaths are the second leading cause of unintentional injury deaths for children aged 0-17 years and the leading cause for those aged 1-4 (1). Previous studies using national data have shown that unintentional drowning deaths can differ by sex, age, race and ethnicity, and urban-rural category (2,3). This report uses the latest mortality data from the National Vital Statistics System (NVSS) to present national trends in unintentional drowning death rates from 1999 through 2019 for children aged 0-17.

This report uses the most recent data from the National Vital Statistics System (NVSS) to update statistics on deaths from drug overdose in the United States, including information on trends from 1999 through 2019 by sex and age group, and by specific types of drugs involved (i.e.

Increase in Drug Overdose Deaths Involving Cocaine: United States, 2009-2018.

Deaths from drug overdose continue to contribute to mortality in the United States. The rate of drug overdose deaths involving cocaine has increased in recent years (1-3). This Data Brief provides additional information on drug overdose deaths involving cocaine by examining trends in rates by sex, age group, race and Hispanic origin, and by concurrent involvement of opioids from 2009 through 2018.

Rates of Alcohol-induced Deaths Among Adults Aged 25 and Over in Urban and Rural Areas: United States, 2000-2018.

Excessive alcohol consumption is a well-known risk factor for mortality and has been causally linked to many diseases, conditions and injuries, including alcohol-attributable cancer, liver cirrhosis, and alcohol poisonings (1). Alcohol-induced deaths, or deaths from dependent and nondependent use of alcohol, as well as accidental poisoning by alcohol (2), have been increasing in the United States since 1999 with differences by sex, age, urban-rural classification, and other demographic characteristics (3,4). This Data Brief focuses on alcohol-induced deaths among adults aged 25 and over, which account for more than 99% of the alcohol-induced deaths in the United States.

National Hospital Care Survey Demonstration Projects: Opioid-involved Emergency Department Visits, Hospitalizations, and Deaths.

Objective-This report demonstrates the utility of linking the restricted-use 2014 National Hospital Care Survey (NHCS), 2014-2015 National Death Index (NDI), and 2014-2015 Drug-Involved Mortality (DIM) data to study opioid-involved emergency department (ED) visits, hospitalizations, and mortality within 1 year post-discharge. Example research questions and unweighted results are presented. Results are not nationally representative.

The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) External Cause-of-injury Framework for Categorizing Mechanism and Intent of Injury.

Background-External cause-of-injury frameworks, or matrices, based on the International Classification of Diseases (ICD) provide standardized categories for reporting injuries by mechanism and intent of injury. In 2014, the National Center for Health Statistics (NCHS) and the National Center for Injury Prevention and Control (NCIPC) published a proposed external cause-of-injury matrix for use with data coded using the ICD, 10th Revision, Clinical Modification (ICD-10-CM). At the time the proposed matrix was developed, ICD-10-CM coded data were not available to evaluate the performance of the proposed matrix.

Objective-This report describes regional differences in the specific drugs most frequently involved in drug overdose deaths in the United States in 2017. Methods-Data from the 2017 National Vital Statistics System-Mortality files were linked to electronic files containing literal text information from death certificates. Drug overdose deaths were identified using International Classification of Diseases, 10th Revision underlying cause-of-death codes X40-X44, X60-X64, X85, and Y10-Y14.

Drug Overdose Deaths in the United States, 1999-2018.

Deaths from drug overdose continue to contribute to mortality in the United States (1-5). This report uses the most recent data from the National Vital Statistics System (NVSS) to update trends in drug overdose deaths for all drugs and for specific drugs and drug types, and to identify changes in rates by state from 2017 to 2018.

An Updated International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) Surveillance Case Definition for Injury Hospitalizations.

The National Center for Health Statistics (NCHS) and National Center for Injury Prevention and Control (NCIPC) have routinely collaborated with injury epidemiology partners to develop standard injury surveillance case definitions based on the International Classification of Diseases (ICD). With the transition in October 2015 to the use of the ICD, 10th Revision, Clinical Modification (ICD-10-CM) for reporting medical information in administrative claims data, NCHS and NCIPC proposed an ICD-10-CM surveillance case definition for injury hospitalizations. At the time, ICD-10-CM coded data were not readily available, and the proposed surveillance definition could not be tested using real data.
