Medical Protection defines a Good Samaritan act as one in which medical assistance is given, free of charge, in a bona fide medical emergency upon which you may chance, in a personal as opposed to a professional capacity, eg, assisting a fellow spectator at an event.
For doctors, ignoring such a predicament is never an option. When called into action while off duty, you must remember to make a full clinical record after treatment. There will be millions of people at the Games and, in this scenario, you must assess your own competence in handling the situation – eg, you may be under the influence of alcohol – and proceed accordingly.
Only intervene if the situation is an emergency. Any situation that is beyond your competence may still benefit from your input, to a degree. For example, you can use your clinical skills to take a history, make an examination to reach a preliminary assessment, and give an indication of the likely differential diagnosis. You can also suggest options for the management of the situation pending arrival of support.
In the unlikely event that legal proceedings follow, members would be entitled to apply for assistance, no matter which country the legal proceedings are commenced in, which is important as many spectators will be drawn from around the world.
