Injuries and accidents are one of the major causes of death, hospital admissions and disabilities in Luxembourg. A large number of injuries could be avoided if more information was available on their causes and circumstances. Therefore, in 2012, an accident and injury monitoring system (in French REcueil de données sur les TRaumatismes et ACcidEnts ) was set up in Luxembourg collecting information from all injury cases treated in the emergency departments of the country’s hospitals. RETRACE is the result of close collaboration between the Ministry of Health, the partner hospitals and the Luxembourg Institute of Health.

Accident and injury surveillance and prevention is a flagship programme in Europe with many countries involved.

The Luxemburgish injury monitoring system RETRACE is an active member of the European Injury Data Base Network (IDB-Network) is a systematic injury surveillance system that collects accident and injury data from selected Emergency Departments (EDs) of hospitals using a common European methodology. Injury data provide complementary information to other existing data sources, such as routine causes of death statistics, hospital discharge registers and data sources specific to injury areas, including road accidents and accidents at work. 


This accident and injury surveillance system in Luxembourg is used to:

• collect information on the number and nature of injuries and accidents (by year),

• Identify the places of occurrence and the circumstances of injuries 

• identify the severity of accidents and their consequences,

• Study the population groups that are the most seriously affected (adolescents, elderly, etc.)

• analyze objects and materials involved in accidents,

• measure the individual, social and economic impact of accidents and injuries,

• set up a prevention program  adapted to the Luxembourg context.

RETRACE methodology 

RETRACE uses the common European IDB-network methodology. Injury cases are selected based on reason of the visit registered by a nurse at ED’s triage or if at least one International Classification of Diseases (ICD-10) code of injury is used by the medical doctor. Based on collected information it is possible to classify injuries according to the prevention domains. To manage the recording and validation of more than 60 000 cases registered every year, Luxembourg Institute of Health (LIH) has developed an innovation data collection approach using machine learning techniques for data recording and validation with the aim to reduce the time consuming manual coding.
