Long-Term Outcomes after Perioperative and Intensive Care – Max Bell research group

Our research focuses on morbidity and mortality after major surgery and critical illness. Long-term outcomes after perioperative and intensive care.

Our research

Around 50 000 patients are treated in Intensive Care Units and more than 800 000 patients undergo surgery and anesthesia in Sweden every year. With perioperative and intensive care offered to an elder and comorbid population complications increase, contributing to long-term morbidity. In the perioperative setting complications increase risk of death five-fold. Perioperative death, within 30 days following surgery, has been reported to be the 3rd leading cause of mortality, exceeded only by heart disease and cancer.

We have multiple ongoing projects regarding long-term mortality and morbidity after perioperative care; focusing on myocardial injury and -infarction, acute kidney injury as well as cognitive dysfunction and stroke. We are investigating intraoperative hypotension and other modifiable factors. For future interventional trials to be effective it is essential to focus on the right patients, those with the highest risk of adverse events; can we describe these at-risk-individuals? What are the perioperative risks of stroke, pneumonia and acute kidney injury? We also study potential effects of wireless monitoring of high-risk patients in the postoperative and post intensive care setting.

With regards to critical illness and multiorgan failure, we investigate the impact of acute kidney injury (AKI) and study both kidney injury biomarkers- and functional biomarkers and their association with long-term outcomes. Is it possible to detect patients at risk for further renal deterioration and can interventional programs minimize that risk?

Our research

Our research focuses on mortality and morbidity following major surgical procedures and critical illness.

Approximately 50,000 patients are treated in intensive care units, and over 800,000 patients undergo surgery and anesthesia in Sweden each year. When perioperative and intensive care are provided to an older and sicker population, the risk of complications increases, contributing to elevated long-term mortality. Perioperative complications quintuple the risk of death. Perioperative mortality within 30 days after surgery has been reported as the third leading cause of mortality, surpassed only by heart disease and cancer.

Our group has several ongoing projects examining long-term risks of death and morbidity after perioperative care, with a focus on heart injury and infarction, acute kidney injury, as well as cognitive dysfunction and stroke. We investigate intraoperative blood pressure drops and other modifiable factors. To make future interventional studies effective, it is essential to identify high-risk patients, those with the greatest risk of complications; can we characterize this population? What are the perioperative risks for stroke, pneumonia, and acute kidney injury? We also explore the potential benefits of wireless monitoring of vital parameters for postoperative and post-intensive care patients.

Concerning critical illness and multi-organ failure, we study acute kidney injury (AKI) and how kidney injury and function markers can predict long-term outcomes. Can we detect patients at risk of future kidney function impairment, and can interventional programs reduce that risk?
