Antibiotic Guidelines in ICU
Antibiotic guidelines vary between ICUs. This variation is based on local causes of infections, resistance patterns, availability and patient factors. However, the principles of appropriate use of antibiotics are universal... as are the common errors!
Pulseless Electrical Activity
Pulseless electrical activity (PEA) occurs when organised or semi-organised electrical activity of the heart persists but the product of systemic vascular resistance and the increase in systemic arterial flow generated by the ejection of the left ventricular stroke volume is not sufficient to produce a clinically detectable pulse

Data Distributions
Data can be described by different distributions, which has implications for how the data is analysed using statistical methods
Fisher’s Exact Test
Fisher's Exact Test is to compare categorical data; more complicated to perform than the Chi square test; only generally applicable in 2 x 2 contingency table
Hazard Ratio, Median Ratio and Kaplan-Meier Curves
Time-to-event curves analyzed by Cox proportional hazards regression are useful for analysing events occurring over time; uses all available information, including patients who fail to follow up or reach the endpoint (censored data)
ICU Outcomes
Outcome measures are important for research and quality control; clinically meaningful outcomes measure how patients feel, function or survive, e.g. mortality, quality of life
Intention to treat analysis
Intention to treat (ITT) analysis means all patients who were enrolled and randomly allocated to treatment are included in the analysis and are analysed in the groups to which they were randomized
