advocate provides; pt education, medication reconciliation and education;

EDPP model emphasizes addressing psychosocial and medical issues that
emerge after discharge.
14.Medical decision making - ANSWER ✔ making is a process that you are
continuously evaluating and refining based on new data you obtain. To be
particularly skilled in this, you must be cognizant of the biases you may
bring to your evaluation of the patient's case and the human errors that can
occur during the course of evaluation management. A good clinician looks at
both for their own errors and the errors of colleagues and make the necessary
corrections to avoid harm to the patient.
