Abstract
The Korea National Hospital Discharge In-depth Injury Survey (KNHDIS), which was started in 2005, is a national probability survey of general hospitals in Korea with 100 or more beds conducted by the Korea Disease Control and Prevention Agency (KDCA). The KNHDIS captures approximately 9% of discharged cases from sampled hospitals using a 2-stage stratified cluster sampling scheme, among which 13% are injury related cases, defined as S00-T98 (injury, poisoning, and certain other consequences of external causes) using International Classification of Diseases, 10th revision codes. The KNHDIS collects information on characteristics of injury-related discharges in order to understand the scale of injuries, identify risk factors, and provide data supporting prevention policies and intervention strategies. The types of data captured include the hospitals’ information, detailed clinical information, and injury-related codes such as the mechanism, activities undertaken when injured (sports, leisure activities, work, treatment, and education), external causes of the injury, and location of the occurrence of the injury based on the International Classification of External Causes of Injuries. Furthermore, the means of transportation, risk factors for suicide, and toxic substances are recoreded. Annual reports of the KNHDIS are publicly accessible to browse via the KDCA website (http://www.kdca.go.kr) and microdata are available free of charge upon request via email (kcdcinjury@korea.kr).
Highlights
Injuries constitute a major public health problem, killing more than 5 million people (9% of deaths) worldwide each year and causing many more cases of disability
In Korea, the death rate from injuries has dropped from 61.2 per100 000 in 2009 to 56.5 in 2019, with traffic accidents accounting for approximately 10% of deaths in aged 1- 29 group in 2019[1]
In-depth Injury Survey (KNHDIS) with hospital based data, patients’ demographic data, details on injury, and contextual data in order to understand the scale of injuries, identify risk factors, and provide data supporting prevention policies and intervention strategies suggested by the WHO injury surveillance guidelines
Summary
Injuries constitute a major public health problem, killing more than 5 million people (9% of deaths) worldwide each year and causing many more cases of disability. In-depth Injury Survey (KNHDIS) with hospital based data, patients’ demographic data (age, sex, and geographic area), details on injury (intent, place, mechanism, nature of injury), and contextual data (date of admission and discharge, outcomes, payment information) in order to understand the scale of injuries, identify risk factors, and provide data supporting prevention policies and intervention strategies suggested by the WHO injury surveillance guidelines. It is an integrated system of data collection, analysis, interpretation and communication. The KNHDIS defines patients with injury-related discharges as S00-T98 (injury, poisoning and a few other consequences of external causes) of the International Classification of Diseases, Tenth Revision (ICD-10) [4], which was designated in addition to the main diagnosis or sub-diagnosis code
