Examples of adverse events following discharge from the ICU:
(1) infection (pneumonia, sepsis, etc)
(2) fall or other accidental injury
(3) acute myocardial infarction
(4) pulmonary embolism
(5) pulmonary edema
Risk factors identified on multivariate analysis:
(1) respiratory rate
(2) heart rate

number of risk factors =
= SUM(points for the risk factors)
Additional risk factors:
(1) high level of nursing care required (p = 0.06)
(2) hypoxia (oxygen saturation < 90%) (a risk factor for a major adverse event in univariate analysis)
Interpretation:
• minimum number of risk factors: 0
• maximum number of risk factors: 2 (from the multivariate model)
• The more risk factors present the greater the risk of an adverse event.
