There are disagreements about whether crystalloids should be used alone or in combination with albumin. This question has important implications because albumin is an expensive blood product in relatively limited supply, and 20% of its use is by heart surgery patients. The goal of this study is to learn more about how crystalloids and albumin are used during heart surgery, as well as, key patient outcomes., conditionsModule conditions: Cardiovascular Surgical Procedures, conditions: Albumin, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: RETROSPECTIVE, enrollmentInfo count: 500, type: ESTIMATED, armsInterventionsModule, outcomesModule primaryOutcomes measure: Albumin, primaryOutcomes measure: Crystalloid, volume dose and type administered, eligibilityModule sex: ALL, minimumAge: 18 Years, maximumAge: 99 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Royal Columbian Hospital, city: New Westminster, state: British Columbia, zip: V3L 3W7, country: Canada, contacts name: Michael Law, MD FRCPC, role: CONTACT, contacts name: Ramanjot Kaur, MSc, role: CONTACT, geoPoint lat: 49.20678, lon: -122.91092, locations facility: Vancouver General Hospital, city: Vancouver,, state: British Columbia, zip: V5Z 1M9, country: Canada, contacts name: Darren Mullane, MB BCh BAO FRCPC FCAI FJFICM, role: CONTACT, geoPoint lat: 49.24966, lon: -123.11934, locations facility: Nova Scotia Health Authority, city: Halifax, state: Nova Scotia, zip: B3H 3A6, country: Canada, contacts name: Pieter de Jager, role: CONTACT, geoPoint lat: 44.64533, lon: -63.57239, locations facility: McMaster University Medical Centre, city: Hamilton, state: Ontario, country: Canada, contacts name: Michelle Zeller, MD FRCPC, role: CONTACT, geoPoint lat: 43.25011, lon: -79.84963, locations facility: Kingston Health Sciences Centre, city: Kingston, state: Ontario, zip: K7L 3N6, country: Canada, contacts name: Jeannie Callum, MD BA FRCPC, role: CONTACT, geoPoint lat: 44.22976, lon: -76.48101, locations facility: London Health Science Centre, city: London, state: Ontario, zip: N6A 5A5, country: Canada, contacts name: Christopher Harle, MD, role: CONTACT, contacts name: Ziad Solh, MD MSc FRCPC, role: CONTACT, geoPoint lat: 42.98339, lon: -81.23304, locations facility: University of Ottawa Heart Institute, city: Ottawa, state: Ontario, zip: K1Y 4W7, country: Canada, contacts name: Diem Tran, role: CONTACT, contacts name: Bernard McDonald, role: CONTACT, geoPoint lat: 45.41117, lon: -75.69812, locations facility: Sunnybrook Health Sciences Centre, city: Toronto, state: Ontario, zip: M4N 3M5, country: Canada, contacts name: Yulia Lin, MD FRCPC, role: CONTACT, geoPoint lat: 43.70011, lon: -79.4163, locations facility: St. Michael's Hospital, city: Toronto, state: Ontario, zip: M5B 1W8, country: Canada, contacts name: Katerina Pavenski, MD, role: CONTACT, geoPoint lat: 43.70011, lon: -79.4163, locations facility: Toronto General Hospital - University Health Network, city: Toronto, state: Ontario, zip: M5G 2C4, country: Canada, geoPoint lat: 43.70011, lon: -79.4163, hasResults: False
