Figure 1. Primary Effectiveness and Safety End Points and Death. Panel A shows the cumulative incidence of the primary effectiveness end point of all hospitalizations for heart failure within 24 months of follow-up among patients who underwent transcatheter mitral-valve repair and received guideline-directed medical therapy (device group) and among those who received guideline-directed medical therapy alone (control group). The data shown here do not account for the competing risk of death, which was considered in the joint frailty model. A total of 160 hospitalizations for heart failure occurred in 92 patients in the device group, and a total of 283 hospitalizations for heart failure occurred in 151 patients in the control group. Panel B shows the rate of the primary safety end point of freedom from device-related complications at 12 months among the 293 patients in whom device implantation was attempted, as compared with an objective performance goal. Panel C shows time-to-event curves for all-cause mortality in the device group and the control group. Stone, G.W. et al.

Innovative Advanced Practice Provider (APP) Program Delivers Enhanced Patient-centered Care Objectives Describe the APP role in identifying practice needs and creating a systematic role for personnel and protocols to improve health care delivery Identify how innovating cardiovascular care delivery by optimizing provider scope of practice mirrors scientific discovery and understanding Summarize guidelines and future directions for high quality and efficient care of cardiovascular patients referred for cardioversion or cardiac monitoring 2 7 of 25

Why? When asked why we started the cardioversion program.. 3 Why not? Where does it say who can/cannot push that button? 4 8 of 25

Objectives Describe the APP role in identifying practice needs and creating a systematic role for personnel and protocols to improve health care delivery Identify how innovating cardiovascular care delivery by optimizing provider scope of practice mirrors scientific discovery and understanding Summarize guidelines and future directions for high quality and efficient care of cardiovascular patients referred for cardioversion or cardiac monitoring 5 Wouldn t it be better if Free EP MD to perform complex procedures Create a dedicated and streamlined serviceline for easy patient referrals and increase patient volume Identify patients who are candidates for advanced EP therapies Expedite patient access to care Prevent patients from falling through the cracks Arrange for appropriate follow up Optimal patient care with appropriate diagnostics for ongoing bestpractice care 6 9 of 25

EP APP performing DCCV What is needed Experimentation with innovative concept Practice collaboration APP willing to step out of comfort zone System Support EP & MHI Leadership Anesthesia partners Medical staff office & credentialing Prep/recovery staff 7 To Err is Human Institute of Medicine released the report To Err is Human: Building a safer Health System Outcomes of the paper Nationally/locally define events Develop reporting systems Necessity of individual accountability of health professionals with unacceptable, reckless behavior Organizations held accountable for unsafe conditions 8 10 of 25

Most important message was initially lost in the report Developing safety in patient care is more important than defining error Freedom from accidental injury is the responsibility of a system 9 Improving safety in care requires Respecting abilities by developing processes that recognize our strengths and weaknesses. Then capitalize on strengths 10 11 of 25

Refocus learning Change the focus from individual growth within a practice to becoming a stronger system 11 The Grey Zone The space between all the disciplines This is where the most opportunity to optimize patient care is created It can also be the hardest to achieve as it typically requires a change of culture and tradition 12 12 of 25

Identification of EP Grey Zones Cardioversion (2009 EP only, 2013 all of MHI) Tilt Table Testing (2009) Implantable Loop Recorder Placement (2014) Implantable Loop Recorder Removal (2018) Requires Collaboration to Optimize Care within this zone 13 Collaboration Term is commonly used to describe hierarchical relationships Collaborative team effort is often described as interdisciplinary structure with an MD as the supervisor of the team 14 13 of 25

True Collaboration Defined as: A partnership based on mutual respect for one another s expertise, knowledge, and skills Territorial issues dissolve 15 Collaboration is not determined by the independence of a provider Practice with a boss dominated perspective becomes inefficient and we risk becoming less beneficial for our patients 16 14 of 25

Greatest Challenge To learn, use, and share better information 17 Objectives Describe the APP role in identifying practice needs and creating a systematic role for personnel and protocols to improve health care delivery Identify how innovating cardiovascular care delivery by optimizing provider scope of practice mirrors scientific discovery and understanding Summarize guidelines and future directions for high quality and efficient care of cardiovascular patients referred for cardioversion or cardiac monitoring 18 15 of 25

Experimentation 19 What is described as a scientific approach to medical experimentation to look at ectopic arrhythmias and the excitable gap 20 16 of 25

Discovering the Solution 1752 Ben Franklin was knocked senseless several times by lightning Stated :If there is no other use for discovered for electricity, this, however, is something considerable that it may help make a vain man humble? 1775 a single shock (via Leyden jar) to a chicken resulted in lifelessness. A repeat shock given at which time the bird took off, eluding any further shocks 1879 brought the first accidental electrocution (development of commercially available electric power) Later found that the majority of these deaths were due to ventricular fibrillation 1899 electrical currents were applied directly to the heart of dogs to induce vfib only in the foot notes did it state that the charges could also terminate the vfib 1932 scientists looked at DC shock, but concluded that AC shocks gave superior results 1940 & 1947 study confirmed the effectiveness of defibrillating the exposed heart patients needed a thoracotomy and direct application of electrodes limited usefulness 1960 looked at AC vs DC being used for rhythms other than vfib This led to using A.C shock (transthorasic) to terminate refractory arrhythmias 21 Discovering the solution What we knew No standardized regimen for anticoagulation Scattered Cardiologist Workflow Pulling from CV/EP lab, hospital service, special diagnostics (CT, MRI, Nuclear, Echo) Missed patient follow up Variation in practice between providers, covering providers, communications/orders Precious resources: lab time, TEE, anesthesia, bedside nursing 1 procedure at a time in 1 designated CV prep/recovery room, no oversite or guidelines followed (pre, peri, or post procedure) 22 17 of 25

What others have taught us MHI CVDS Dr. Hurrell Integrated TEE guided cardioversions to be a single sedation procedure in CV prep/recovery All elective cardioversions performed on 1 floor/unit for care 23 Seeing What We Have to Gain Above all provide the highest quality of care, efficiently, to our patients in a true collaborative practice In addition. Develop professional expertise Develop a program that pushed boundaries to develop the APP role in an innovative practice that would become tomorrows standard Challenge traditional provider roles 24 18 of 25

A touch of what we think might work.. Having an APP care for patients schedule for elective cardioversion procedure & perform the procedure. Cardioversions were a clear grey zone in MHI s CV practice and care delivery system 25 Program Growth 2009 started with cardiac EP patients 2013 formally expanded to all MHI patients 26 19 of 25

Delivery of care through safe and efficient care Changed the standard of care at ANW for patients undergoing a cardioversion procedure Improved the efficiency of the cardiologist and the APP Provide a full service evaluation Anticoagulation review from systematic approach to best practice Better utilized anesthesia and bedside RN resources Optimize and enhance the APP through volume and experience 27 APP Directed Cardioversion Program Outcomes 2009 2010 2011 2012 2013 2014 2015 2016 2017 # cardioversions 801 904 847 947 984 1058 1278 1341 1473 % of cardioversion procedures that had a stroke within 48 hours (2 days) of cardioversion 0.12% (n=1) 0.22% (n=2) 0.24% (n=2) 0.11% (n=1) 0.30% (n=3) 0.28% (n=3) 0.39% (n=5) 0.37% (n=5) 0.20% (n=3) Research incidence of stroke report at 0.6 1.8% 20 of 25

NP Run Outpatient Cardioversion Program Stanford Health Program developed in 2012, published in 2016 Retrospective study from 2009 6/2014 557 subjects, underwent 869 DCCVs (5.5 years) = ~160 DCCV/year Demonstrated NP run DCCV are safe and effective with results comparable to MD run DCCVs. 29 Objectives Describe the APP role in identifying practice needs and creating a systematic role for personnel and protocols to improve health care delivery Identify how innovating cardiovascular care delivery by optimizing provider scope of practice mirrors scientific discovery and understanding Summarize guidelines and future directions for high quality and efficient care of cardiovascular patients referred for cardioversion or cardiac monitoring 30 21 of 25

Anticoagulation Guidelines 2009: only agents on market were warfarin & heparin products 2011 added NOAC (now DOAC) 31 Heparin Protocol Heparin protocols at ANW updated to include APTT Heparin protocol hold parameters 32 22 of 25

Implantable Loop Recorder (LINQ) Historically conscious sedation, 90 minutes EP lab time, 2 EP techs, 1 RN, and 1 EP MD. This equated to 360 RVU time New technology (LINQ) simplified implant & MHI adapted to best care with fiscal responsibility Moved procedure to CVOP room using local anesthetic, 1 RN, 1 APP, 30 minute procedure. Equates to 60 RVU time Developed relationship with neurology team (Sherilyn Milner, NP & Dr. Young leads) Evidence based medicine CRYSTAL AF trial with cryptogenic stroke patients 34 REVEAL devices in 2014, almost 200 LINQs annually since 2015 growth and best patient care Implantable Loop Recorder (LINQ) Outcomes Passed our 4 year anniversary of APP placing (~700 devices) <0.5% infection rate Few devices removed early/2 repositioned due to patient request (irritation, 18 y.o., diagnosis made, well endowed) Cryptogenic Stroke EP team/mhif Intern study: 84 day average time to detection of arrhythmia Changes therapy to full anticoagulation 20 25% of patients diagnosed with cryptogenic stroke are found to have atrial arrhythmia on LINQ device 23 of 25

Implantable Loop Recorder (LINQ) Removals 2018 brought with it End of Life (EOL) for LINQ devices..now what Gornickism of 2018: If you can put them in, you should take them out Moved to Prep/recovery using APP and 1 assist If we can feel it (all placed SQ), 1 2cc epi/lido, a 10 11mm incision, and hemostat Concern raised for incision closure with steri strips. Brought back 10+ patients to MHI for site check. All with uncomplicated healing 35 Dollars and Sense Simple math. pay a cardiologist vs advanced practice provider to perform cardioversion, ILR, ILR removal Revenue from EP MD to perform complex procedures Access to care: increased patient volumes (cardioversions, ILR, and advanced EP procedures), EP lab availability for complex procedures, expedited patient access to care, easy scheduling, patient satisfaction Sense.. Safe patient care, patient access to care, efficiency of practice, optimal utilization of precious resources, improved patient identification for advanced therapies, etc. 24 of 25
