Objective

To describe the epidemiology of interpersonal violence in Spain.

Method

Descriptive study of the cases of patients with secondary diagnosis of aggression registered on a national hospital discharge database, between 1999 and 2011, using the codes from E960 to E969 of the ICD-9. The distribution by sex, age and type of discharge, associated morbidity, mortality and by autonomous community is described. The quality of the record is studied according to its temporal variation.

Results

The case profile of aggression in men (85%) is of a patient between 15 and 44 years old, who in 93.7% of cases requires urgent care and whose severity is moderate (95% discharge home). Two point five percent of patients are readmitted and death occurs in1.1%. The profile in women (15%) differs slightly, with an age between 31 and 52 years, 94% require urgent attention, although 96% have moderate severity; 3% are readmitted and 1.7% die.

Conclusions

Although they need to be improved to avoid certain limitations, health information systems are a rich source of data that can be used for research in health and, through their results, for the development of prevention plans and intervention in matters of violence.
