• The Canadian Institute for Health Information (CIHI) manages two trauma registry databases (1, 2):
1. National Trauma Registry (NTR): NTR collects data on injury hospitalizations in Canada
2. Ontario Trauma Registry (OTR): OTR collects information on injury hospitalizations and injury deaths in Ontario.
• The Ontario Trauma Registry is used to identify, describe and quantify trauma injuries in Ontario. This registry is funded by the Ministry of Health and Long Term Care and managed by the Canadian Institute of Health Information (2).
• Goals of the registries are to contribute information to increase awareness of injuries; support injury-related research; and provide evidence in support of prevention and treatment programs to facilitate the reduction of injuries and related deaths (2).
• The OTR has three data sets (1, 2):
1. The Minimal Data Set (MDS) contains demographic, diagnostic and procedural data on all injury admissions to acute care hospitals in Ontario.
2. The Comprehensive Data Set (CDS) has detailed patient information, administrative and clinical data such as pre and post hospital care, patient outcomes and a 6 month follow-up.
3. The Death Data Set (DDS) has information on all deaths due to trauma. Data includes demographics, cause of death, details of the injury and other factors contributing to the death.
• For detailed information about these data sets, including years of availability, please refer to http://www.cihi.ca/cihi-ext-portal/internet/en/document/types+of+care/specialized+services/trauma+and+injuries/otr_metadata
• OTR data comes from the Discharge Abstract Database (DAD), 11 trauma centres and the Office of the Chief Coroner of Ontario. The 11 trauma centres located across 14 sites are: Children's Hospital of Eastern Ontario, Ottawa; Hamilton Health Sciences Corporation, Hamilton (2 sites); Hospital for Sick Children, Toronto; Hôtel-Dieu Grace Hospital , Windsor; Kingston General, Kingston; London Health Sciences Centre, London (2 sites); The Ottawa Hospital, Ottawa (2 sites); Health Sciences North/Lake Ramsey Health Centre, Sudbury; St Michael's Hospital, Toronto; Sunny Brooke Health Sciences Centre, Toronto and Thunder Bay Regional Health Sciences Centre, Thunder Bay (2).
