Population Health Research Data Repository
- Clinical Health Data: Critical Care/ICU -

Source Agency Winnipeg Regional Health Authority (WRHA)
Type Clinical health
Purpose The WRHA Department of Medicine and Critical Care established the Critical Care Medicine Information Management and Research (CCMIMR) program for administrative, research, and quality assurance purposes. The Critical Care program was established in Winnipeg as a continuous quality improvement initiative in 1988 for Intensive Care Units (ICU), and Medicine was added in 2003.

Just over 6,000 ICU episodes for critically ill individuals occur every year in 21 ICUs in 16 hospitals in Manitoba (approximately 5% are for non-Manitobans). Of the 118 certified ICU beds (2007/08), only the 91 ICU beds in 6 urban hospitals are "full service", i.e., capable of caring indefinitely for the full range of critically ill patients, staffed continuously by certified ICU physicians (Intensivists) and specially trained ICU nurses.

Scope The Critical Care database contains detailed information for every person admitted to any adult ICU in 6 Winnipeg hospitals: Health Sciences Centre, Grace Hospital, St. Boniface General Hospital, Victoria, Concordia, and Seven Oaks. This includes MICU, SICU, IICU, CICU, and CCU wards. (ICU beds represent just over 3% of adult acute care hospital beds in the province.)
Data Collection Method Data are electronically collected from the hospital chart by a group of specially trained ICU nurses and is managed by the CCMIMR. Extensive reliability and validity testing takes place, including much effort spent on validating patient identifiers.
Size About 5,000 to 6,000 individuals per year, with over 1,000 data fields.
Data Level Each record represents an admission or a transfer from an ICU service unit or ward; it is possible for several records to be present for an individual person.
Data Years 1999/2000 onward for all six hospitals.
(Health Sciences Centre was the first hospital for which data was collected, from 1988/89 onward. Data collection began for Grace Hospital in 1998/99. St. Boniface General Hospital, Victoria, Concordia, and Seven Oaks all began in 1999/2000.)
Data Components Registry, Acute Physiological and Chronic Health Evaluation (APACHE), lab tests, Therapeutic Intervention Scoring System (TISS)
