    • To assess the patient's recovery and condition for a safe discharge or transfer 
  • Appropriately apply criteria for safe discharge from or bypass of the PACU to the following: 
         1. Home 
         2. inpatient ward 

         3. Intensive care unit

INTERPERSONAL AND COMMUNICATION SKILLS, PROFESSIONALISM

  • See general competencies section
  • Ability to communicate postoperative information to the surgical team accurately and efficiently, particularly when postoperative problems may be related to surgical complications.

 PRACTICE-BASED LEARNING AND IMPROVEMENT

  • See general competencies section
  • Learn to evaluate and manage patients so that time spent in PACU is appropriate and not prolonged by unmanaged pain, nausea and vomiting or concomitant medical problems. 
  • Practice self education by using down-time between patient arrivals from the operating room for independent study (see Teaching Resources for details on reading material) 
  • Participate in the education of PACU nursing staff by giving one 15- to 20-minute presentation on a topic relevant to postanesthesia care. (PACU medical director available to assist) 
     

SYSTEMS-BASED PRACTICE

  • See general competencies section
  • Learn to work with nursing and administrative personnel to get patients as quickly as possible to their longer term recovery sites (home, floor, ICU) thus allowing for efficient continuing care in the operating room and preventing PACU related delays in surgery.
  • Learn study design, data collection, and when appropriate, manuscript writing by participating in departmental studies in the PACU when they are underway 

Evaluation to Determine Goal Achievement:

  • Medical director meets with you at the beginning of the rotation to acquaint you with expectations and resources available. At the end of the rotation, you meet with the rotation director to discuss the rotation. 
  • You are evaluated weekly on-line by attendings who worked with you. In this case, the PACU medical director will complete your primary evaluations.  In addition, the five attendings with the greatest volume of patients going through the PACU will also be asked to evaluate your performance.  The evaluation data are reviewed quarterly by the Clinical Competence Committee. Your advisor informs you of any problems identified, and serious problems will be discussed with you immediately after they occur. 
  • You will complete a Departmental Rotation Evaluation Form. 
  • The Program Director will evaluate the results of the In-Training Examination for the American Board of Anesthesiologists (ABA) in general and for areas of departmental weakness. Consistent weaknesses may result in adjustment of the above goals. 

Teaching Resources to Accomplish the Objectives:

  • Patients: > 16,000 per year of all ages and with all types of pathology undergo care at Shands Teaching Hospital, 80% of whom are admitted to the PACU and 20% of whom are admitted directly to an intensive care unit. 
  • Reading material 
    • Text books: available in PACU (titles included with attached bibliography) 
    • Reading file of reprints maintained in PACU (Bibliography attached) 
  • Facilities: An office is available for the resident in PACU with desktop computer for access to patient data, departmental database, and MEDLINE. 
  • Faculty: 
    • General: All teaching faculty participate; all are board eligible or certified anesthesiologists with a commitment to resident education. Many have dual board certification and sub-specialty training with certification where available. Other professionals such as those in the Computer Division assist with such resources as the desktop computer.
