Surgery is a work process, and likewise it requires inputs to achieve the desired output, a recuperating post-surgery patient. Examples of work-process inputs, from Production Engineering, are the five M's — "money, manpower, materials, machinery, methods" (where "manpower" refers to the human element in general). Like all work-processes in ...
Preoperative care refers to health care provided before a surgical operation.Preoperative care aims to do whatever is right to increase the success of the surgery. At some point before the operation, the healthcare provider will assess the fitness of the person to have surgery. This assessment
Randomization ratios The chance of being randomized into one particular group, can change. Treatment groups are not added or dropped, but the chance of being randomized, for example, into the treatment group could increase after interim analysis. This type of design is explained in detail on PANDA. [6] Adaptive treatment-switching Treatment
In practice the odds ratio is commonly used for case-control studies, as the relative risk cannot be estimated. [1] In fact, the odds ratio has much more common use in statistics, since logistic regression, often associated with clinical trials, works with the log of the odds ratio, not relative risk. Because the (natural log of the) odds of a ...
The main approaches for stepwise regression are: Forward selection, which involves starting with no variables in the model, testing the addition of each variable using a chosen model fit criterion, adding the variable (if any) whose inclusion gives the most statistically significant improvement of the fit, and repeating this process until none improves the model to a statistically significant ...
Strong for Surgery (S4S) is a public health campaign and quality improvement (QI) initiative developed and launched by the University of Washington in Washington State in 2012. [1] Strong for Surgery was developed by the Comparative Effectiveness Research Translation Network (CERTAIN) and informed by data from the Surgical Care and Outcomes ...

A risk–benefit ratio (or benefit-risk ratio) is the ratio of the risk of an action to its potential benefits. Risk–benefit analysis (or benefit-risk analysis) is analysis that seeks to quantify the risk and benefits and hence their ratio. Analyzing a risk can be heavily dependent on the human factor.
