Fostering Innovation in Fluid Management

Overview

Achieving the optimal fluid balance with dialysis is extremely difficult. When too much fluid is removed or fluid is removed too quickly, cramps and fatigue often occur. When too little fluid is removed or if patients have too large of weight gains between treatments, bloating, shortness of breath and fatigue often occur. Knowing how much fluid to remove is a huge challenge and is far from a precise science. Such adverse clinical sequelae of imprecise fluid management have substantial impact on long-term clinical and patient-reported outcomes. Chronic volume overload, clinical or subclinical, is associated with increased hospitalizations and mortality.[6] Hypovolemia, either due to inaccurate dry weight estimation or overly rapid fluid removal during dialysis, is associated with clinical and subclinical end-organ ischemia that can lead to long-term organ damage and dysfunction.[2-5, 7, 8] These fluid-related challenges are associated not only with substantial patient morbidity and mortality, but also with high health care system utilization and costs.[9]

In Detail

One of the most challenging issues for dialysis patients and their healthcare providers is accurately determining an individual's ideal weight (dry/target weight). Despite all the technological and engineering advances in medicine over the last several decades, there has been surprisingly little innovation when it comes to volume status estimation. Devices such as non-invasive blood volume monitoring, bioimpedance and lung ultrasound have shown some promise. However, there is currently no FDA-approved device for body weight/composition determination. This is a critical gap in care that has vast implications for patient quality of life and clinical outcomes. Inspired by advances in glucose monitoring and fitness tracking, this project challenges the community to consider innovations that might involve wearables devices with real-time feedback so patients can adjust their behaviors in response to fluid status as well as other innovative technologies that move us away from dependence on in-clinic monitoring devices.

  • Summarize of patient priorities
  • Standardize definitions and terminology
  • Catalogue existing and under-development relevant technologies with needs assessment
  • Produce a guide and stimulate device innovation in fluid management
