Research Interests

Dr. Sandhu is a Cardiac Electrophysiologist at the Rocky Mountain Regional VA Medical Center and Assistant Professor of Medicine at the University of Colorado. His research interests include access to electrophysiology services within the VA system, decision-making surrounding EP procedures and research surrounding treatment of arrhythmogenesis in complex patients (ie. those with ventricular tachycardia, atrial fibrillation and complex congenital heart disease). He is helping lead development and extension of the Clinical Assessment and Report Tool to EP (CART-EP) procedures, including cardiac implantable devices and catheter ablation procedures, across the VA healthcare system. Dr. Sandhu received his BA in biomedical and electrical engineering from the University of Pennsylvania and medical degree from the Georgetown University School of Medicine. He completed his internal medicine residency at the University of Michigan followed by general cardiology, Masters of Clinical Science and electrophysiology fellowships at the University of Colorado.

Development of a Patient-Centered Approach to ICD Decision-Making

Informed shared-decision making is critical to ensure Veteran-centered, values-concordant care. This is especially important regarding implantable cardioverter-defibrillators (ICDs). These permanent devices require an invasive procedure for the implant with the intent to monitor and treat life-threatening arrhythmias. ICDs present a tricky balance of patient benefit (i.e., treatment of dangerous heart rhythms), procedural risk, long-term maintenance, and impact on psychological health (i.e., PTSD, anxiety, and depression from ICD shocks).
Research shows providers overemphasize ICD benefits while patients overestimate benefits and poorly comprehend risks, psychological effects, and complications.
The central hypothesis of this proposal is that the current ICD decision-making process is heterogeneous and needs a more Veteran perspective. Aligned with the VA Strategic Plan, this work will shift this paradigm to a Veteran-centered, shared-decision making process. Broadly, this project can set the standard for Veteran-centered care with application to other invasive cardiovascular procedures.

Development of a Patient-Centered Approach to ICD Decision-Making

Aligned with the VA Strategic Plan and Blueprint for Excellence, it is critical to ensure Veteran-centered, values-concordant care through informed, shared decision-making. This is especially important regarding implantable cardioverter-defibrillators (ICDs). These permanent devices require an invasive procedure for the implant with the intent to monitor and treat life-threatening arrhythmias. ICDs present a tricky balance of patient benefit (i.e., treatment of dangerous heart rhythms), procedural risk, long-term maintenance, and impact on psychological health (i.e., PTSD, anxiety, and depression from ICD shocks).
Given high rates of heart failure among Veterans, ICD implantation rates across the VA have risen sharply over the past decade, with over 25,000 ICDs implanted at an average per-procedure cost of $64,500. However, this rise may not be indicative of well-informed, values-concordant care. Numerous prior studies show patients poorly comprehend the risks, benefits, psychological effects, and complications associated with ICD implantation. Patients often have false impressions that ICD is a “cure” for heart failure, requires no maintenance, and does not lead to inappropriate shocks. Prior data also demonstrate that providers overemphasize the benefit of ICDs.
Nationally and within the VHA, this discord has led to a call for decision-support tools to aid patients in making informed, personalized decisions, particularly for invasive therapies with complex risk-benefit tradeoffs such as ICDs. Innovative aspects include: (1) a significantly improved, comprehensive tool to support ICD communications, (2) a designed for routine implementation within VA clinical care, (3) a study of the transition of tools from a non-VA to VA setting, (4) addressing a high-stakes decision (national mandate by CMS for SDM tools) and (5) integration into existing VA quality-improvement infrastructure (CART-EP).
The central hypothesis of this proposal is that current ICD decision-making processes are heterogeneous and need more Veteran perspectives. We will address this through:
Aim 1: Determine Veteran and VA-provider-specific factors surrounding ICD decision-making.
Aim 2: Develop a VA-provider-led tool that meets Veteran needs for routine use within the VA.
Aim 3: Feasibility testing of the newly developed tools designed to support ICD communications.
After this study, the tools will be ready for rapid testing through an IIR project seeking to evaluate this tool, compared to the standard of care, at multiple VA sites. Dr. Sandhu is leading the development of CART-EP, a VA-funded project extending the use of CART (quality system for invasive cardiovascular procedures) to ICDs. We will incorporate this ICD SDM tool as a quality measure into CART-EP before ICD implantation within the VA. CART-EP will serve as a method to study large-scale dissemination and implementation of this tool nationally.
