“Variation” is an innocent word that that can represent many levels of frustration to the clinician. Variation among patients is the least of these; the physician expects patients and their individual problems to be as diverse as the human race itself. Variation within a practice should be due to matching the specific needs of the specific patient. Other variations can mean trouble if they represent differences in understanding of the problem among clinicians and other allied health practitioners. These differences could be between institutions or even between shifts within one institution.
