The implementation of a real time early warning system using machine learning in an Australian hospital to improve patient outcomes.

Background: Early Warning Scores (EWS) monitor inpatient deterioration predominantly using vital signs. We evaluated inpatient outcomes after implementing an Artificial Intelligence (AI) based intervention in our local EWS.

Methods: A prior study calculated a Deterioration Index (DI) with logistic regression utilising demographics, vital signs, and laboratory results at multiple time points to predict any major adverse event (MAE-all cause mortality, ICU admission, or medical emergency team activation).

Perioperative transfusion and long-term mortality after cardiac surgery: a meta-analysis.

Objectives: Cardiac surgical procedures are associated with a high incidence of periprocedural blood loss and blood transfusion. Although both may be associated with a range of postoperative complications there is disagreement on the impact of blood transfusion on long-term mortality. This study aims to provide a comprehensive review of the published outcomes of perioperative blood transfusion, examined as a whole and by index procedure.

LIMA to LAD grafting returns patient survival to age-matched population: 20-year outcomes of MIDCAB surgery.

Objectives: Previous studies have demonstrated the safety and excellent short-term and mid-term survival after minimally invasive direct coronary artery bypass (MIDCAB). We reviewed the long-term outcomes up to 20 years, including overall survival and freedom from reintervention.

Methods: Consecutive patients who underwent MIDCAB between February 1997 and August 2020 were identified.

Paraprotein associated heparin resistance during cardiopulmonary bypass.

Introduction: Heparin resistance during cardiopulmonary bypass poses a significant intraoperative dilemma. Antithrombin deficiency related heparin resistance is well described, but less common causes are still poorly understood and inadequately managed.

Case Report: We present a case of heparin resistance during cardiopulmonary bypass in a gentleman with no previous haematological history or thrombotic risk factors.
