Capturing the full measure of patient outcome improvement using a self-assessed health adjustment
Journal of evaluation in clinical practice. 2005 Oct; 11(5): 484-8.
Self-assessed health (SAH) status is a very simple four-, or five-category self-reported measure of health status that has been shown to be a powerful predictor of mortality, service use and total cost of medical care treatment. It is therefore reasonable to suggest that pre-intervention SAH may influence the extent to which patient outcomes improve following surgery.
