Evaluation of a Health Care Performance Improvement Initiative to Facilitate Optimal Clinical Outcomes in Patients Receiving Ventricular Assist Device Support.

Background: Ventricular assist device (VAD) patients are at high risk for morbidities and mortality. One potentially beneficial component of the Joint Commission VAD Certification process is the requirement that individual VAD programs select 4 performance measures to improve and optimize patients' clinical outcomes.

Problem Statement: Review of patient data after our program's first certification visit in 2008 showed that, compared to national recommendations and published reports, our patients had suboptimal outcomes in 4 areas after device implantation: length of hospital stay, receipt of early (<48 hours) postsurgical physical therapy, driveline infection incidence, and adequacy of nutritional status (prealbumin ≥18 mg/dL).

Bariatric surgery for a patient with a HeartMate II ventricular assist device for destination therapy.

A patient with a HeartMate II left ventricular assist device who had a body mass index of 52 needed gastric bypass surgery in order to qualify for a heart transplant. Unlike previous experience in which the surgery was performed at the implant hospital, the gastric bypass surgery in this case was performed at a bariatric center of excellence that was a separate facility from the implant hospital. The artificial heart program of the University of Pittsburgh Medical Center worked with the bariatric center of excellence in scheduling the gastric bypass surgery using a multidisciplinary team approach at 2 hospitals to coordinate safe, high-quality patient care in a unique situation.

The Joint Commission's disease-specific care certification for destination therapy ventricular assist devices.

The Centers for Medicare and Medicaid Services announced that all hospitals implanting ventricular assist devices are required to have certification from the The Joint Commission for disease-specific care destination therapy with a ventricular assist device effective March 27, 2009, in order to receive Medicare reimbursement for services rendered to patients who have devices implanted for destination therapy. On February 23, 2007, The Joint Commission released the certification requirements for ventricular assist devices implanted for destination therapy in an 8-page document so that hospitals could prepare to meet the 2009 certification deadline. The Artificial Heart Program of the University of Pittsburgh Medical Center undertook a multidisciplinary project, under the guidance of the nurse coordinator, to prepare the hospital and program for a precertification survey by The Joint Commission for disease-specific destination therapy ventricular assist device certification.

A rapid hemodynamic monitor of acute ischemia during cardiac procedures: changes in relaxation via a continuous left ventricular pressure-derivative loop.

Background: Procedures that induce ischemic pre-conditioning during cardiac surgery will require a rapidly visualized hemodynamic monitor of acute ischemia. This study investigated the utility of a continuous loop tracing of left ventricular pressure (LVP) plotted against its derivative (dP/dt) as a visual beat-to-beat monitor of acute changes in myocardial relaxation due to global ischemia.

Materials And Methods: In 11 dogs, LVP, recorded via a micromanometer-tip catheter, was plotted against dP/dt as a continuous loop.
