Speaking the Same Language? Assessing Blood Pressure Measurement and Effectiveness in Pediatric VAD Patients

Abstract

Purpose Elevated blood pressure (BP) is a risk factor for stroke in adult ventricular assist device (VAD) patients. There are currently no data or BP management guidelines for pediatric VAD patients. ACTION ( Advanced Cardiac Therapies Improving Outcomes Network) is the first pediatric VAD quality improvement network. The initial goal of ACTION is stroke reduction. This report describes the methods used to obtain BP and effectiveness of BP control among ACTION members. We also describe the development of a BP clinical decision support (CDS) tool to standardize BP reporting and goals. Methods The BP protocols among ACTION members were assessed. Process measures that may impact stroke rates were identified via anonymous surveys beginning June 2018. Statistical process control charts were used to assess baseline metrics. Results A total of 28 patients from 11 centers were identified with BP data. Including 12 Heartware, 10 Berlin, 2 Heartmate3, and 4 paracorporeal continuous flow (CF) devices. Height/age BP %iles were used to guide BP goal in 19 (68%) patients. Among CFVAD patients, BP measurement method (outside the perioperative period) and BP goal value varied, especially among the 11 patients (55%) with a palpable pulse (Figure 1). Patients had well controlled BP on 69% of support days (Figure 2). Conclusion The BP measurement methods and goals varied across ACTION, especially among patients on a CF-VAD with a pulse. A CDS tool has been developed to standardize BP measurement and management among ACTION members and will guide subsequent collaborative studies to assess the role of BP in stroke among pediatric VAD patients.
