Vanderbilt Preoperative Evaluation Center- VPEC

My name is Laura Hollis, MSN, CCRN, and I am the interim manager of patient care services for VPEC. My name is Julie Hamm, MSN, ACNP-BC and I am the Clinical Lead NP for VPEC.

VPEC has two locations:  The Vanderbilt Clinic (TVC) and One Hundred Oaks (OHO), both are fully staffed clinics with 11 Nurse practitioners, 5 registered nurses and multiple MA’s and PSR’s. The staff at either location performs: vitals, images, sleep apnea screening and a complete review of systems and history and physical on patients undergoing elective surgeries. The nurse practitioner’s performs these visits in person, while the registered nurses use a virtual phone call model.  We can also arrange for lab work and x-rays to be done at the time of the VPEC visit or through a local primary care doctor for our phone call patients. We gather any outside testing and can order electrocardiograms, cardiac consults, stress tests and echocardiograms if felt needed by the attending anesthesiologist.

Patients are usually referred to the clinic by one of our surgeons for medical optimization prior to the day of surgery. This process allows our team of Nurse Practitioner’s to ensure that preoperative patients are properly evaluated, educated and that all necessary testing and patient information are in hand before procedures. This is a free evaluation to assess the patients’ overall risk for surgery. This better ensures patient safety and helps prevent surgical delays and cancellations on the day of surgery. Once the patient evaluation is completed at VPEC, it becomes part of the patient’s electronic medical record and is accessible by any Vanderbilt medical provider.

VPEC has received several significant industry accolades, including the 2014 Top Performer Award and the coveted 5-Star Award for Overall Quality of Care. This means a score in the 90th – 99th percentile based on results and as compared to similar centers nationwide. The award was given to both VPEC clinic sites. VPEC leadership is frequently consulted by other hospitals wanting to improve their preoperative processes.
