Knowledge Base MOST Form Are old MOST forms (completed prior to 2015 revision) still valid, or do we have to redo MOST forms for all our patients/clients/residents? Is there a Spanish version of the MOST? Does a MOST replace or revoke advance directives? What if MOST orders conflict with the patient’s other advance directives? What if a patient brings in a MOST/POLST/POST/MOLST form from another state that doesn’t exactly comply with Colorado requirements for the MOST?
