The document discusses expanding the meaning of the Hippocratic oath's principle of "first do no harm" to include protecting doctors' own health and wellbeing. It argues that in the complex medical environment of the 21st century, doctors face many challenges that can negatively impact their health if not addressed. These include ethical issues, information overload, resource pressures, changing roles, and workplace stressors like violence and litigation. The document advocates that doctors must proactively care for themselves physically and mentally to best help patients over the long run as healthy practitioners.
