NURSING HOME DIALYSIS Rapidly Growing and Complicated

  • 1 Suresh Samson, MD, FASN, is the Chief Medical Officer for Concerto Renal Services (Concerto), a Chicago-based dialysis provider and one of the nation’s largest providers of nursing home dialysis. In 2018, Concerto provided nursing home dialysis to nearly 1800 patients in Illinois, Indiana, and Wisconsin, and is currently working to implement its model in multiple other states by the close of 2019.

On August 10, 2018, the Centers for Medicare & Medicaid Services (CMS) published updated regulations for dialysis facilities (1). The CMS guidance encompasses several modalities, with a focus on the locations where dialysis services are provided.

The new guidance reaffirmed CMS’ recognition of dialysis in a nursing home setting, making revisions to the State Operations Manual (Chapter 2, ESRD Facilities), adding section 2271A, titled “Dialysis in Nursing Homes.” This action affirmed that Medicare-approved ESRD facilities may provide dialysis services to skilled nursing facility (SNF) residents in the nursing home within an approved home training and support modality. These new requirements include operational, logistical, physical, and staffing guidelines for nursing home dialysis. What follows is a summary of the nursing home dialysis model.

First, let us briefly frame the term “subacute care dialysis” (SACD), which includes dialysis provided in SNFs. Dialysis patients in such facilities may receive hemodialysis or peritoneal dialysis. Hemodialysis in these facilities can be either conventional thrice-weekly treatments or shorter treatments five or six days weekly. As the nursing home peritoneal dialysis population is small and delivery relatively straightforward, this article concentrates on hemodialysis in nursing homes.

While there are nearly 700,000 ESRD patients in the United States (2), the precise number of dialysis patients in nursing homes is unclear. However, using data from the U.S. Renal Data System and CMS, reliable estimates place the number at about 10% of the broader nationwide dialysis population—at approximately 70,000 (2, 3). With the rapid increase in the number of new ESRD patients in the >65 years age group, this number is sure to increase in the coming years.

SACD: the logistics

The framework under which SACD is provided is simple: The nursing home chooses the space in its building to convert into a hemodialysis unit, and it bears the expense of constructing the unit. If conventional thrice-weekly dialysis is sought, a nursing home dialysis unit has many of the physical characteristics of a standalone outpatient unit—just in miniature form. It will have its own water treatment system, dialysis equipment, and traditional dialysis supplies. The nursing home would contract with a home dialysis provider to provide services. CMS guidelines indicate that the ESRD facility can only provide home dialysis services to a nursing home resident under a written agreement with the home, and that the nursing home is charged with maintaining direct responsibility for the dialysis-related care over that patient. Moreover, the quality of such services must remain consistent with the ESRD Conditions for Coverage requirements, as well as the terms of an applicable agreement with the nursing home. The agreement itself must clearly delineate the responsibilities of the ESRD facility and the nursing home regarding the care of the resident before, during, and after dialysis treatments (1).

The new guidance emphasizes the need for communication and collaboration between the dialysis provider and nursing home. There must be a constant, uninterrupted flow of information between the dialysis unit and the nursing home staff, through systematic processes. Unlike traditional in-center dialysis facilities, a nursing home dialysis provider must establish defined mechanisms to ensure that respective staffs are exchanging information, which will lead to timely and appropriate medication administration; knowledge of physician/treatment orders; laboratory values and vital signs; nutritional/fluid management; changes and/or decline in condition unrelated to dialysis; the occurrence or risk of falls; dialysis adverse reactions/complications; and/or recommendations for follow-up observations and monitoring.

As someone overseeing these processes, my recommendation is that the agreement between the two entities clearly set forth each entity’s responsibilities and build in weekly and monthly meetings between appropriate members of the respective interdisciplinary teams to address any nonmedical/clinical needs, general medical/clinical needs, and each patient to assess plans of care and potential problems or issues that could hamper treatment goals.

SACD from a patient’s perspective

In most states, a hemodialysis patient admitted to a nursing home must be transported to a regular dialysis unit three-times weekly. The provision of dialysis in-house eliminates the need for the patient to endure such travel, which carries multiple risks, particularly in cold-weather states. Receiving in-house dialysis treatment, on the other hand, allows patients to spend more time receiving therapy and working to improve their condition and to work toward discharge home.

More time is also afforded for physician visits and recreational time. Whether in-house dialysis reduces the length of nursing home stay is yet to be seen. This model is a great advantage for the patient and his or her family.

SACD from a physician’s perspective

Physicians must be versed with this model to appropriately care for their patients.

First, they will naturally be required to have privileges with the dialysis provider to see patients in the dialysis unit. Because of the need for a significant amount of coordination of care with the nursing home and its staff, however, it would behoove physicians to obtain privileges with the nursing home as well. Given that patients have multiple comorbidities and a higher acuity than the average in-center patient, their medication regimen often changes with more frequency, increasing the utility of having access to both the dialysis provider and nursing home’s systems for better control and management of such patients.

Of note, CMS considers SNFs to be the patient’s home (4). Therefore, these patients are required to be seen at least once a month as is the case with conventional home dialysis patients. This is an important distinction between SACD and the in-center setting. Although patients can be scheduled to see physicians in their own clinics, my recommendation is to do the monthly physician examination in the nursing home—and not necessarily during dialysis. This offers the physician the opportunity to better coordinate the patient’s care and facilitates a discussion of care plans with the interdisciplinary team.

Physicians may also discover opportunities to serve as medical directors with nursing home dialysis providers. Because each dialysis unit has a small capacity, this may include overseeing care at multiple nursing home dialysis units. Physicians may use such opportunities to build relationships with area nursing homes and hospitals, while also assisting nursing homes with the crafting and implementation of their policies and procedures, which are essential for the proper care of dialysis patients.

General pitfalls to avoid

  • ■ Ensure that your name is entered on the nursing home patient’s chart as the nephrologist, with your contact details.

  • ■ Obtain privileges with both the dialysis provider and the SNF. You will be unable to provide orders directly if you do not have SNF privileges.

  • ■ Familiarize yourself with both electronic medical record (EMR) systems.

  • ■ Owing to the high proportion of patients with multidrug-resistant infections, familiarize yourself with infection control policies of both the dialysis provider and SNF.

  • ■ Communicate with the interdisciplinary team for both the dialysis provider and the SNF.

  • ■ Evaluate patients monthly. It is not required that you examine patients while they are receiving dialysis. They may be examined outside the dialysis unit.

  • ■ Develop a team of cardiologist, vascular surgeon, and interventionalist to coordinate access placement.

  • ■ Ensure communication to the patient’s regular dialysis unit about any changes during the nursing home stay.

Physicians must be aware of certain clinical challenges that are unique to this model of dialysis care. Nearly 30% of ESRD patients are admitted to SNFs in the last 90 days of life (5). Preliminary unpublished data on 1800 ESRD patients who underwent dialysis in 2018 by Concerto Renal Services—one of the nation’s largest nursing home dialysis providers, which performs thrice-weekly hemodialysis—show the following:

  • ■ Only 50% of patients achieved an anemia goal between 9 and 11 g/dL.

  • ■ Nearly 25% had phosphorus levels <3 mg/dL.

  • ■ Nearly 40% had albumin <3.5 g/dL in spite of adequate protein supplementation.

  • ■ 40% of patients had a >90-day catheter rate.

  • ■ There was a 35% readmission rate for patients admitted with hemoglobin <8 g/dL compared with <10 g/dL for others.

Multiple variables may account for these findings. First, dialysis patients in nursing homes tend to be sicker, with more comorbidities and ongoing inflammation, mostly in the setting of conditions like decubitus ulcers, urinary catheters, colitis, and diabetic ulcers. Their nutritional status is often poor, reflecting the high proportion of patients with low phosphorus levels. Physicians and medical directors will also face the challenge of getting access placement for this population, mainly due to the shorter length of stay in nursing homes and patients’ multiple comorbidities requiring extensive evaluation for surgical clearance.

SACD from a nursing home perspective

On-site dialysis improves the efficiency of nursing homes by reducing the need for transportation arrangements for dialysis. Because of the above-mentioned advantages, it is likely that a nursing home with on-site dialysis will attract more patients.

On-site dialysis also saves on healthcare costs. A study by Stephens et al. estimated the national cost of dialysis transportation for the year 2014 to be nearly $3.2 billion. The cost per dialysis patient per year was estimated to be about $8300 (6).

Despite nursing homes’ bearing the costs of building the dialysis unit, on-site dialysis can rightfully be seen as a prudent investment. Given the growth in the number of elderly dialysis patients, this is an essential service and will benefit the nursing home in the long run.

This care model is an evolving one, with the prospect of additional clarity from the CMS in the coming years as the number of nursing home dialysis patients rapidly increases. As with any healthcare model, this one must retain quality patient care as the core principle, and all parties will benefit.
