In 2015 , the European Society of Anesthesiologist (ESA) and the European Society of Intensive Care Medicine (ESICM) proposed 22 adverse events (with severity grading) and 4 composite outcome, healthcare resource use and quality of life measures to evaluate postoperative outcomes [Jamer et al, Eur J Anaesthesiol 2015; 32:88-105].
Though these measures were intended to standardize reporting in large perioperative clinical trials, the authors also suggested value for clinical audit.
22 Single Organ Outome Measures
Acute Kidney Injury (AKI)
Acute Respiratory Distress Syndrome (ARDS)
Pneumonia
Deep Venous Thrombosis (DVT)
Pulmonary Embolus
Cardiogenic Pulmonary Edema
Myocardial Infarction
Myocardial Injury after non-cardiac Surgery (MINS)
Cardiac Arrest
Arrhythmia
Stroke
Anastomotic Breakdown
Paralytic Ileus
Gastrointestinal Bleed
Postoperative Hemorrhage
Delirium
Infection (unknown source)
Bloodstream Infection
Superficial Surgical Site Infection
Deep Surgical Site Infection
Organ/Space Surgical Site Infection
Urinary Tract Infection
4 Composite Outcome Measures
An advantage of using composite outcome measures is increased observed event rate to increase statistical power:
[If frequency of event is 1 in a 100 versus 1 in 10,000, an intervention difference can be apparent with much fewer observations].
Major Adverse Cardiac Event (MACE)
Postoperative Pulmonary Complications
Postoperative Morbidity Survey (POMS)
Quality of Recovery (QoR)
