You are a medical student on rotation in the emergency department with Dr. A. A patient comes in complaining about pain in their hip. Dr. A gives them some medication and the patient very quickly appears to improve and leaves the hospital feeling better. After the patient leaves, Dr. A reveals that the drug was a placebo and that that particular patient comes in often with a pain complaint that "has no pathological basis". Dr. A says that in cases like that, a placebo can be enough to help patients feel better and that telling patient it is a placebo would ruin the effect.
What ethical issues do you see here? Would you say anything to Dr. A? Should you report this behaviour?
