In general, ambulance squads are unable to contravene the wishes of a mentally competent patient. This may lead to situations of likely cardiac compromise, likely internal trauma, or other life-threatening situations. However, if the patient is of sound mind, they are generally able to refuse treatment. The EMS provider has limited options at this point, since EMS generally cannot restrain and take a person involuntarily. However, depending on local policy, the police may be able to place the patient in protective custody (essentially arresting the person and releasing them to the EMS agency). This option is not to be pursued lightly. This is typically termed the RMA-AMA (refusal of medical assistance against medical advice) to differentiate it from a standard RMA (which may be assumed to be the end to a trivial call)
