In mid-winter and mid-summer, my office phone starts ringing in earnest. “John, you’ve got to get in here. Our volume is going through the floor.” These normal seasonal lulls in patient volume are often misinterpreted by clients as the harbinger of disaster. In a few cases, these concerns are warranted. But more often, light clinics and surgical calendars are driven by normal seasonal market forces, some of which are under administrative control. Slips in volume that you can’t control can at least be predicted and braced for in advance.
