Patients with end-stage kidney disease who receive dialysis can significantly reduce their emergency room visits by having a primary care physician, according to new research that challenges the fragmented approach to kidney disease care. A study of over 181,000 Medicare patients found that those with primary care involvement had a 51.2% estimated risk of emergency room visits that didn't result in hospitalization, compared to 72.1% for those without a primary care doctor. What Does This Study Actually Show About Dialysis Care? Researchers from the University of Michigan examined Medicare records from 2018 through 2019 to understand how primary care involvement affects emergency department use among patients with end-stage kidney disease (ESRD), the most severe stage of chronic kidney disease (CKD) where the kidneys function at less than 15% capacity. The findings were published in JAMA Network Open, a peer-reviewed medical journal. The differences were striking across multiple measures. Patients with primary care involvement had a 69.4% estimated risk for any emergency room visit, while those without primary care had a 75% risk. This 5.6 percentage point difference may seem modest, but when applied to the hundreds of thousands of dialysis patients nationwide, it represents a substantial reduction in preventable emergency visits. "Given that primary care involvement may help reduce ED utilization, including partnerships with primary care practices may be one method to reduce total costs of care," stated Kunal Bailoor, M.D., from the University of Michigan in Ann Arbor.

Why Do Dialysis Patients Often Fall Through the Cracks? Patients with end-stage kidney disease typically receive care from multiple specialists, including nephrologists (kidney doctors) who manage their dialysis treatment. However, this specialized focus can sometimes leave gaps in overall health management. A primary care physician serves as a coordinator who can address broader health concerns, manage chronic conditions like diabetes and hypertension, and catch problems before they become emergencies. The research suggests that having someone overseeing the patient's complete health picture, rather than just their kidney function, makes a meaningful difference. This coordination becomes especially important for dialysis patients, who are already dealing with complex medical needs and frequent medical appointments. How to Improve Kidney Disease Care Through Primary Care Coordination - Establish a Primary Care Relationship: Dialysis patients should identify and regularly see a primary care physician who understands their kidney disease and can coordinate with their nephrologist to prevent gaps in care. - Communicate Between Providers: Ensure your primary care doctor and nephrologist share information about your medications, recent lab results, and any new symptoms or concerns you're experiencing. - Schedule Regular Check-ups: Maintain consistent primary care visits rather than only seeing specialists when dialysis-related issues arise, allowing early detection of problems that might otherwise lead to emergency room visits. - Report Symptoms Early: Contact your primary care physician about any new symptoms, changes in how you feel, or concerns between dialysis sessions rather than waiting until symptoms become severe enough to warrant an emergency visit. What Could This Mean for Healthcare Costs and Future Care Models? The researchers emphasized that their findings have important implications for how kidney disease care is organized and paid for. Currently, healthcare systems often reimburse specialists and emergency departments separately, which can create financial incentives that don't reward coordination. The study suggests that future care models should explicitly incentivize primary care involvement in patients with end-stage kidney disease. If healthcare systems could reduce emergency room visits by 20 percentage points (the difference between 72.1% and 51.2%), this would translate to fewer unnecessary emergency visits, reduced strain on emergency departments, and potentially significant cost savings across the healthcare system. For individual patients, fewer emergency room visits means less disruption to their lives and potentially better overall health outcomes. The study examined a large, representative population of Medicare beneficiaries, making the findings broadly applicable to the millions of Americans receiving dialysis. However, the researchers noted that future care models should test whether explicitly building primary care partnerships into dialysis treatment programs can sustain these benefits and improve other health outcomes beyond emergency room utilization.
