Christopher Moriates, MD| January 1, 2018
Following a positive fecal immunochemical test (a screening test for colon cancer), a colonoscopy was ordered for a 50-year-old man. Two months later, the nurse called him to see if he had obtained the colonoscopy. The patient reported that he was unable to schedule it due to cost of the copayment. The primary physician called the insurance company and was informed that the colonoscopy would be covered in full if the indication was written as preventive rather than diagnostic. Ultimately, the patient received the colonoscopy and was diagnosed with colon cancer 6 months after his initial positive screening test.
Carlton R. Moore, MD, MS| August 1, 2012
Drawn on a Thursday, basic labs for a 10-year-old girl came back over the weekend showing a high glucose level, but neither the covering physician nor the primary pediatrician saw the results until the patient's mother called on Monday. Upon return to the clinic for follow-up, the child's glucose level was dangerously high and urinalysis showed early signs of diabetic ketoacidosis.

At her last visit in June before the year-end transfer, the patient was unable to schedule a follow-up visit because the new residents' schedules were not yet in the system. The delay in care had deadly consequences.
