Oncologist Dr. Catriona McNeil writes about a severe adverse outcome her patient suffers in The Journal of Clinical Oncology’s “Grace and Forgiveness.”

Dr. McNeil treats her patient, Liz, who also happens to work in the same hospital, with a standard chemotherapy for breast cancer. When Liz suffers a rare but known possible complication from her chemotherapy, McNeil finds herself grappling with feelings of guilt, of responsibility. She initially wonders if she made a mistake, if there could be some other cause to her patient’s catastrophic decline: “The chemotherapy order had been checked and rechecked. Had I made a mistake? … She’d had nowhere near a cardio-toxic dose of chemotherapy. No, it couldn’t be that. Until eventually it could no longer be anything else.”

McNeil considers the early clinical studies of the chemotherapy she used, how those oncologists also might have “sat with a distraught family in a tiny room and had the same awful conversation. And yet how bland and unthreatening those little rows of text in the medical journals had seemed. How they’d sat so neatly in a small font near the bottom of the toxicity tables—cardiac death, 0.1% or thereabouts; just a handful of patients. Rare. Unlikely.”

This essay illustrates the limitations of medicine and the bias of human nature. It’s difficult to acknowledge we or our patients could suffer a detrimental complication, especially when it’s statistically rare. McNeil conveys the weight prescribing providers carry when such an event occurs. Although we all know, as patients and physicians, that there are no guarantees in medicine, it is jolting to experience what McNeil calls “the trauma of an adverse patient outcome.” Even though there “had been no malice or intent, no mistake or neglect,” McNeil still harbors guilt as she alone “had signed the chemotherapy order.”

Any treatment advised, from ibuprofen to chemotherapy, can have dire side effects. Learning to grapple with those consequences and continue to move forward with empathy for both self and the patient poses a great challenge to the medical profession.
