US Healthcare Ethics: Physician-Assisted Death and Medical Aid in Dying

"Medical aid in dying (MAID) is now authorised in fourteen US jurisdictions: twelve states with statutes — Oregon, Washington, Vermont, California, Colorado, Hawaii, Maine, New Jersey, New Mexico, Delaware, Illinois and New York — plus the District of Columbia, and Montana, where the practice is permitted not by statute but by the state Supreme Court's 2009 ruling in Baxter v. Montana. The three newest laws are very recent: Delaware (signed May 2025, in force 1 January 2026), Illinois (signed December 2025, in force September 2026) and New York (signed 6 February 2026, in force 5 August 2026), so the Illinois and New York statutes are enacted but not yet operative.", where a terminally ill, mentally competent adult with a prognosis of six months or less can request a lethal prescription. A terminally ill patient in one of these states tells you she is seriously considering requesting MAID. How do you respond clinically and as a matter of professional ethics?

Likely follow-up · What is the difference between medical aid in dying, euthanasia, and palliative sedation — and does the distinction matter morally?

AAMC Core Competency: Teamwork and Interprofessional Collaboration

During a hospital volunteering shift, you observe a disagreement between a nurse and a resident physician about the dosing of pain medication for a post-operative patient. The nurse believes the prescribed dose is too low and the patient is in unnecessary distress; the resident insists the dose is appropriate and walks away without further discussion. You are neither a nurse nor a physician. What do you do, and what does this scenario reveal about the importance of interprofessional teamwork in patient safety?

Likely follow-up · How would your approach change if you were a medical student on that rotation rather than a volunteer?
