10. Limitations of care Check advanced directives Establish current diagnosis, treatments required and likely prognosis Establish premorbid state Discuss with likely inpatient treating team (eg ICU) Discuss with patient (although confused) Determine NOK and discuss with them Find agreed position Document the plan
