Decline in hospitalisations due to dog bite injuries in Catalonia, 1997–2008. An effect of government regulation?

ObjectiveTo analyse population-based data on hospitalisation caused by dog bite injuries after changes in legal regulations on dog ownership, including breed-specific regulations.DesignDescriptive study.SettingHospitals in Catalonia (Spain), 1997–2008.SubjectsPersons hospitalised with injuries caused by dog bites.ResultsThere has been a significant decline in hospitalisation caused by injuries from dog bites from 1.80/100 000 in 1997–9 to 1.11/100 000 in 2006–8, after the enactment of stricter regulations on dog ownership in 1999 and 2002. The magnitude of this change is significant (−38%), and has been greatest in less urban settings.ConclusionsGovernment regulations were associated with a sizable decrease in injuries caused by dog bites in Catalonia. More evaluative studies in this field may provide criteria to focus future regulations and other preventive interventions.
