Key Objectives

Given a patient with acute abdominal pain, the candidate will diagnose the cause, severity, and complications and will initiate an appropriate management plan. In particular, the candidate will identify those patients requiring emergency medical or surgical treatment.

Enabling Objectives

Given a patient with acute abdominal pain, the candidate will

  1. list and interpret critical clinical findings, including
    1. historical features, such as
      1. the onset, frequency, duration, location, radiation, quality, and severity of pain; and
      2. aggravating and alleviating factors; and
    2. features of an appropriate physical examination, such as
      1. results of an abdominal examination;
      2. signs of peritonitis; and
      3. results of rectal and genitourinary examinations if relevant;
  2. list and interpret the critical investigations, including appropriate laboratory and diagnostic imaging investigations; and
  3. construct an effective management plan, including
    1. determining whether the patient requires an emergency surgical procedure or emergency medical care;
    2. outlining a management plan for nonemergency conditions; and
    3. determining whether the patient needs specialized care and/or further investigation.
