Statistical Treatment of Surgical Outcome Data T2 Cardiac Surgery in the Adult, 4e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-163310-9 LK accesssurgery.mhmedical.com/content.aspx?aid=55912307 RD 2024/10/04 AB The results (outcome) of cardiac surgery can be measured in several ways. The type of variable used as the measure of a particular outcome determines the statistical methods that should be used for its analysis. For example, some administrative outcomes are captured by continuous variables, such as hospital charges (in dollars) or length of stay (in days). Other outcomes are collected as categorical variables, such as discharge destination (eg, acute-care facility, specialized nursing facility, or home). Health-related quality of life is another kind of outcome, which is often measured by the Medical Outcome Study (MOS) 36-Item Short-Form Health Survey (SF-36),1 the Sickness Impact Profile,2 or disease-specific quality-of-life measures, and can be transferred to quality-adjusted life years (QALYs).3 Economic endpoints have been used increasingly, such as cost-effective ratio.4
