Taking it one step at a time: eHealth Exchange advances toward CMS-Aligned Network readiness. From real-world patient access to nationwide scale, eHealth Exchange continues to lead as CMS requirements evolve. From Progress to Proof: Demonstrating Individual Access At eHealth Exchange, interoperability isn't theoretical - it's operational. As part of ongoing industry collaboration with the Centers for Medicare and Medicaid Services (CMS), eHealth Exchange is working with b.well Connected Health, a digital health platform for AI-powered consumer experience, and DaVita(R), a comprehensive kidney care provider, to demonstrate a real-world individual access use case, showcasing how patients can securely access their health records through a trusted consumer application. This end-to-end production demonstration was highlighted at the CMS Health Technology Ecosystem event in Washington, DC (April 9). In this scenario, a kidney patient uses the b.well app to securely request and retrieve their medical records from a DaVita location, with eHealth Exchange serving as the trusted network intermediary through the Carequality framework. This is more than a demonstration - it's a proof point. For DaVita, empowering patients with seamless access to their health data is a critical component of supporting individuals managing complex, chronic conditions like end-stage kidney disease, which enables greater engagement, continuity of care, and informed decision-making. For eHealth Exchange and b.well, it shows that secure, standards-based patient access is not a future goal, it's already happening today. And importantly, it reflects something that sets eHealth Exchange apart: eHealth Exchange is not building from scratch to meet CMS-Aligned Network requirements - eHealth Exchange is building on almost two decades of real-world trusted interoperability experience. eHealth Exchange helped pioneer workflows to support individual access queries as mobile apps and consumer-directed healthcare began to emerge. The use case has been live for a decade sitting dormant because an IAS query currently does not require a response. Today's work builds directly on that foundation, and eHealth Exchange is thrilled the use case is getting prime time attention with CMS involvement. Where the Industry Stands As the healthcare industry works toward CMS-Aligned Network requirements, one thing is clear: this is not a "flip-the-switch" moment; it's a journey. To date, no network that has pledged to become a CMS-Aligned Network has fully met all minimum viable product (MVP) requirements, largely because key technical and policy definitions are still being finalized across CMS Health Tech Ecosystem (HTE) workgroups. But progress isn't on hold - and neither are eHealth Exchange. How eHealth Exchange Is Moving Forward eHealth Exchange is actively advancing capabilities across all seven CMS-Aligned Network MVP requirements: * Advancing Patient Matching: eHealth Exchange is aligning its patient matching practices with CMS HTE efforts and advocating for stronger identifiers - such as Member ID - to improve accuracy, particularly for payer-related exchange. With participation from 57 regional and state HIEs, its network is uniquely positioned to scale improved matching nationwide. eHealth Exchange believe matching can be improved if eHealth Exchange extend beyond national networks or peer-to-peer exchanges by leveraging those HIE connections. * Expanding Access to Complete Patient Data: Its infrastructure already supports both structured and unstructured data exchange using IHE and FHIR APIs. eHealth Exchange is now working with participants to accelerate access to unstructured content, including scanned and faxed documents, ensuring more complete query responses.For example, its experience using FHIR APIs for non-Treatment exchange to support the FDA and NIH has proven the ability to query for both structured and non-structured data and documents. Additionally, using the IHE traditional standards and querying with various class codes can successfully return non-structured documents. * Supporting All Core Use Cases: eHealth Exchange enables data exchange across patient, provider, and payer use cases, with tailored workflows to support each. eHealth Exchange is also extending this work into federal agencies and public health, including bi-directional exchange initiatives with organizations such as CDC's Immunization Gateway. * Scaling Purpose of Use (TPO and Beyond): eHealth Exchange currently support Treatment, Payment, and Operations (TPO) and are actively expanding capabilities for non-treatment use cases through participation in HL7 Da Vinci and Helios accelerators, as well as federal partnerships with FDA, SSA, and NIH. * Contributing to the National Provider Directory: eHealth Exchange maintain a robust provider directory today and are committed to sharing this data with CMS as part of the National Provider Directory initiative while also helping shape best practices based on its experience. * Leading Audit Log Innovation: As the lead of the HTE Audit Log Workgroup, eHealth Exchange is helping define how networks provide transparency into who accessed data, when, and for what purpose - a cornerstone of trust in nationwide exchange. eHealth Exchange is excited to enable IAS access to audit events on its network. * Maintaining HITRUST Certification: Security remains foundational. eHealth Exchange has maintained HITRUST certification for years, reinforcing its commitment to protecting sensitive patient data. More Than Readiness - Real-World Leadership While CMS-Aligned Network MVP requirements continue to evolve, eHealth Exchange is not waiting for final definitions to take action. Many of the capabilities being outlined today - patient access, multi-use case exchange, purpose of use, and audit transparency - are areas where eHealth Exchange has already delivered at scale for years. What's changing now is not the vision, but the alignment and acceleration of these capabilities across the broader ecosystem. Moving Forward, Together CMS-Aligned Network readiness is a shared industry responsibility. Achieving it will require collaboration, iteration, and a focus on practical implementation. eHealth Exchange remains committed to: * Advancing capabilities today - not waiting for perfection * Collaborating across the ecosystem * Delivering real-world interoperability that benefits patients, providers, and payers eHealth Exchange may not be at the finish line, but eHealth Exchange is demonstrating what's possible every step of the way.

A digital guardian: ai-powered insights bring patients and clinicians closer. | key takeaways combatting home modality loss: to help address the 30% of patients who leave peritoneal dialysis (PD) - a home treatment option - within two years of starting treatment, DaVita developed and deployed a predictive AI model that supports clinical teams in identifying patients needs to sustain home dialysis. Closing the visibility gap: DaVita's connected cyclers and CWOW system provide care teams with consistent patient updates and data to support adjusted care plans and tailored interventions before complications arise. Seamless transitions: when a transition off peritoneal dialysis is necessary, DaVita's pd-to-hhd pathway enables and empowers patients to transition to home hemodialysis (HHD) in a mean of 6 days. "Clinical teams now have better visibility into home treatments, equipping teams with insight on how to address issues before they escalate." - Dr. Mihran Naljayan |. For approximately 80,000 Americans, home dialysis offers a sense of normalcy and stability amid many changes that inevitably come with a diagnosis of kidney failure. Home dialysis includes both peritoneal dialysis (PD) and home hemodialysis (HHD), differentiated options that allow patients to complete treatments with greater schedule flexibility. This not only provides a greater sense of control over treatment but also reduces the need for frequent trips to dialysis centers, giving patients time back to pursue employment, education, time with loved ones and personal hobbies. Supporting patients with home treatments and sustaining success on therapy, like PD, requires a vigilant and proactive approach from care teams: "Sustaining success on home dialysis requires true partnership with our patients," Mihran Naljayan, MD, chief medical officer of clinical transformation, home and pediatric modalities for DaVita, says. "We must work hand-in-hand with patients to support their well-being and their success on their treatment of choice." Data from the National Institutes of Health show that home dialysis has steadily expanded during the past 10 years. In 2012, less than 9% of patients with newly diagnosed kidney failure chose home dialysis. By 2023, that statistic had increased to almost 15%. "Impressive as that trend is, home dialysis would have expanded even more rapidly if patients were able to dialyze at home for a longer duration," explains Eric Weinhandl, PhD, an epidemiologist at DaVita who has published dozens of studies about home dialysis. "Within two years of starting PD, more than 30% have transferred to in-center hemodialysis, whether because of medical complications or psychosocial obstacles, including a sense of burnout."[1] Complicating matters is that the transfer from PD to in-center hemodialysis is often accompanied by hospitalization.[2] Weinhandl says, "Historically, we may have been too reactive, not proactive, when patients were struggling the most with home dialysis." Now, advances in artificial intelligence (AI) are providing clinicians with powerful new tools to support their patients. Kidney care leader DaVita has developed a predictive model that leverages machine learning to help clinical teams recognize and anticipate patient needs before they become critical problems. The tool, known as the PD Loss predictive model, extracts hundreds of variables from a patient's health record and creates a list of individuals each week who are at relatively high risk of discontinuing PD therapy during the next 90 days.[3] This report helps care teams understand when people need extra support as well as why someone has been flagged as higher risk for transitioning off PD. When a patient is identified, the system can suggest specific interventions, such as a medication review or a consultation with a specialist. The model doesn't dictate care, though. Rather, it offers evidence-backed insights to inform care. Based on this feedback and interactions with the patients, nurses can tailor care activities with data-driven insights. "When nurses initiate interventions within 5 days of a patient being identified as high-risk, we see that patients have approximately 15% lower risk of transferring to in-center hemodialysis during the next 2 to 3 months," explains Weinhandl based on internal data from DaVita. Keeping care close when dialyzing from home. What's driving the availability of new technology? Data. In the past, patients recorded treatments on paper and delivered this information to their care team when they saw them - often monthly. Now, at-home devices are helping close the gap between the home and the dialysis center. At DaVita, the majority of patients treating on PD or HHD use connected cyclers - the machines that perform treatment - that record and integrate treatment data into their clinical profile within DaVita's cloud-based platform, Center Without Walls(TM)(CWOW(TM).[4] This gives care teams unprecedented visibility into what's happening with a patient's health while treating at home, tracking everything from treatment adherence to fluid removal trends. "The physiologic and lifestyle benefits of home dialysis are readily apparent," Dr. Naljayan says. "Historically, it has been difficult for the physician to manage the home dialysis treatment regimen in a timely manner, given once-a-month updates about blood pressure and fluid removal. Connected cyclers change that. Clinical teams now have better visibility into home treatments, equipping teams with insight on how to address issues before they escalate." Supporting patients through their kidney health journey. This data stream can also help clinical caregivers create pathways for safer, more thoughtful patient care journeys. This includes supporting DaVita teammates (employees) as they empower home dialysis patients in their "PD to HHD" pathway. This pathway helps identify PD patients who have one or more well-established risk factors for transfer to hemodialysis and provides education about HHD, a therapy that can allow the patient to continue dialyzing at home if the efficacy of PD eventually diminishes. In a Kidney360 study published in 2022, Weinhandl reported that only 3% of patients who transfer from PD to hemodialysis select HHD. By flagging these patients early, care teams can provide enhanced education and proactive planning, whether it includes education, training, or helping the patient get a fistula (a dialysis access) placed if needed. A pilot study of DaVita's "PD to HHD" education process, presented at the 2025 National Kidney Foundation Spring Clinical Meeting, demonstrated a significant increase of people transitioning to HHD when PD was no longer an option. The study also highlighted that early education helped patients start HHD quickly, with a mean transition of just 6 days and the majority of patients making the transition without needing in-center hemodialysis.[5] "We remain focused on supporting patients on their treatment of choice," Dr. Naljayan adds. "Harnessing the power of predictive analytics and real-time data, we are building a more connected care ecosystem. The simple reality is that home dialysis requires effort, but that effort can unlock huge upsides. Our mission at DaVita is to share the load of that effort exerted by patients and their families." By combining the vast analytical power of AI with the irreplaceable expertise of clinicians, healthcare providers can create a more responsive, personalized and sustainable system of care that helps patients manage their health from their preferred environment: at home.
