CMS has launched new knowledge for its Dialysis Facility Examine Star Score system for Medicare- licensed dialysis amenities. There are new “scientific” rankings, primarily based on facility efficiency on the eight scientific measures used on this score system for the interval of 2015 to 2018, in addition to up to date affected person expertise of care rankings primarily based on the In-Middle Hemodialysis Client Evaluation of Healthcare Suppliers and Methods (ICH-CAHPS) surveys carried out between April 2018 and January 2019.

The knowledge is revealed on the Dialysis Facility Examine web site (www.medicare.gov/dialysisfacilitycompare).

Whereas the durations lined by the 2 forms of star score programs basically overlap, facility star rankings primarily based on scientific measures have low correlation to star rankings primarily based on sufferers’ expressions of their expertise of care on the facility and from their nephrologists (Desk 1). Whereas the 2 programs are directionally constant (larger rankings on one system are related to larger common rankings on the opposite system), the general correlation between affected person star rankings and the scientific star rankings is 0.23. In reality, there have been 10 amenities that acquired 5 stars from CMS on scientific measures however acquired one star from their sufferers.

Affected person stars, CMS stars

Of notice are the comparatively small variations in common affected person star rankings throughout the 5 scientific star classes. Amenities with one star (scientific) have a mean of two.8 stars from sufferers, whereas five-star amenities have a mean of three.6 stars from sufferers. Checked out one other manner, whereas 27% of the amenities included on this evaluation received 5 scientific stars from CMS, 11% received 5 stars from sufferers. This can be partly on account of variations in scoring methodology as a result of the affected person star rankings are literally a mean of six-star rankings on measures associated to the dialysis facility, the power employees and the nephrologist. Averaging six scores between one and 5 will possible have a tendency to cut back variation within the composite rating.

Nonetheless, on condition that the aim of the star rankings is to make it simpler for customers to identify excellence in well being care high quality when selecting or evaluating dialysis amenities, the vast divergence in scores on the 2 five-star score programs is considerably problematic. Clearly, elements that matter most matter to sufferers as mirrored within the ICH-CAHPS surveys are sometimes totally different than what CMS makes use of to fee the scientific high quality of care at a facility. Research have proven affected person beliefs and values and doctor perceptions of such usually are not at all times the identical.1-3 Whereas a facility might look good on scientific measures, sufferers might not really feel that they’re getting the eye they need from employees.


Facility traits

What are the traits of amenities receiving 5 stars from sufferers that set them aside from amenities that received fewer stars? We checked out a number of dimensions of facility traits to see how five-star amenities in contrast, together with facility dimension (stations), possession kind and geography. Desk 2 highlights some key traits the place patient-rated five-star amenities differ from amenities with fewer stars. 5-star amenities usually tend to be small, non-profit, unbiased or hospital-based and in rural areas.

The obvious adverse affiliation between dialysis group/facility dimension and affected person star rankings has an fascinating parallel within the hospital setting, the place in a research lately revealed in JAMA Inner Drugs,4 affected person high quality rankings of hospitals had been discovered to diverge from extra goal standards for hospital service high quality resembling comprehensiveness of providers. Hospital sufferers gave larger rankings to smaller hospitals that are inclined to handle sufferers with easier wants. Consider how, equally, one may favor the native household owned ironmongery store for easy issues in comparison with the extra impersonal and typically bewildering expertise typical in a mega-store like a House Depot.

Socioeconomic disparities

It’s definitely potential that the traits of the sufferers themselves might play an necessary function in perceptions of the standard of their expertise of care and impact the star rankings. Some analysis has proven affected person traits are extra necessary in how amenities are rated than the precise high quality of the power.

To look at this, we seemed on the traits of sufferers and of the neighborhoods the place dialysis amenities are situated for clues concerning the make-up of the affected person base in amenities rated 5 stars in comparison with these with decrease rankings. We linked every facility ZIP code to U.S. Census Bureau statistics from the most recent (2017) American Group Survey 5-year estimates5 to look at the socioeconomic traits of the neighborhoods the place amenities are situated, and in addition seemed on the demographic traits of the particular sufferers at every facility, as of Dec. 31, 2017, pulled from the FY2019 Dialysis Facility Reviews (Tables 3 and 4).6

The amenities rated 5 stars by sufferers are typically in neighborhoods which are predominantly larger in common revenue, with larger common schooling and residents who’re older and with fewer black sufferers and minorities. The sufferers themselves at these amenities additionally are typically older, white, male, with a shorter time on dialysis, but in addition extra prone to be in a nursing residence. Conversely, one- and two-star amenities are in communities with extra black sufferers, and total larger minority populations and decrease incomes.


Comparable financial and racial disparities had been present in a lately revealed research of the function of social danger elements on high quality incentive program (QIP) efficiency.7 Within the research, unbiased amenities in city areas with the very best QIP penalties even have the next proportion of low revenue, minority and dual-eligible sufferers. It could be that these sufferers are harder to handle clinically, which may damage QIP and star score scores.

Affected person satisfaction

A number of research have seemed on the hyperlink between affected person traits and higher expertise of care. Outcomes of a Dialysis Clinic Inc. inside evaluation from 2011 reported that older, white sufferers with shorter dialysis classic had been extra glad.8 A follow-up research in 2012 additionally discovered some associations between affected person age, race and gender with ICH-CAHPS rankings that had been directionally much like this research, however discovered the mode of survey administration (phone vs. mail) was by far the strongest determinant of how sufferers reported their care experiences.9 Phone administration led to larger rankings than mailed surveys, once more emphasizing the significance to sufferers of the personalised expertise. Different analysis emphasizes the function of racial and gender concordance between affected person and doctor.10 The physician-patient relationship is strengthened when sufferers see themselves as much like their physicians, which is in flip related to larger rankings of belief and satisfaction. Race concordance was the first issue affecting perceived private similarity.


5-star score programs for customers have inherent flaws no matter what providers are being rated. Reviewer bias is clearly one potential drawback, as is rankings creep, which makes it laborious to tell apart the highest suppliers on account of clustering within the four- to five-star classes.11 Nonetheless, as CMS has now given equal visibility to its scientific star rankings of dialysis facilities and to affected person expertise of care star rankings, additional analysis might assist disentangle the explanations for the vast divergence within the two score programs, which is able to hopefully result in a clearer, extra comprehensible broadened view of dialysis care high quality.
