An example of expected outcome/prognosis is typically clinically based. Expected outcome/prognosis is what the expected outcome of complying with the care plan would be. You can think about it as if a patient follows all instructions of the care plan what you are expecting to happen (e.g., their A1C/BMI/stroke risk etc. will decrease). Generally, we see practices differentiate treatment outcome/prognosis as a more clinical metric, for instance lowering A1C by 2 points etc.
Treatment goals are more lifestyle choices or outcomes for the patient, such as eating more vegetables or getting enough exercise to be able to walk around the block etc.
All of these elements are incorporated into the care plan: a problem list, expected outcome/prognosis, treatment goals, medication management and a schedule to review and revise the plan, as needed.
