Anderson, a nephrologist, share a common patient, Mr. Johnson. He is 77 years old, has ischemic cardiomyopathy, and an eGFR of 20 ml/min per 1.73 m 2 . The buzzing of his arteriovenous fistula reminds him of the prospect of a future life on dialysis. Although he had the arteriovenous fistula placed 2 years ago, he is unenthusiastic about dialysis, not aware of alternatives, and has recurring thoughts of suicide. When Dr. Smith spoke with Dr. Anderson about ligating the fistula, Dr. Smith was told the patient would need it for dialysis.
