Primum non nocere is a Latin phrase that means… “First, do no harm.“ It is one of the principal precepts all medical students are taught. It reminds a physician/golf teacher…. that he or she must consider the possible harm that any intervention might do.
It is most often mentioned when debating use of an intervention with an obvious chance of harm but a less certain chance of benefit. The phrase has been a hallowed expression for physicians of hope, intention, humility, and recognition that human acts with good intentions may have unwanted consequences!
