Final answer:
The MOLST is a medical order for those with serious health conditions, ensuring treatment preferences across healthcare settings, while advance directives are legal documents outlining care preferences without the same legal weight.
Step-by-step explanation:
The difference between advance directives and the MOLST form is that the MOLST form, which stands for Medical Orders for Life-Sustaining Treatment, is a medical order that applies to individuals with serious health conditions and is used to direct healthcare professionals in providing life-sustaining treatments based on a patient's preferences. Meanwhile, advance directives are legal documents that anyone can create to outline their preferences for medical care in the event that they become unable to make decisions for themselves but do not carry the same legal weight as a medical order like MOLST. The MOLST form is designed to travel with a patient across healthcare settings, ensuring continuity of care based on their expressed treatment preferences.
