The Staffing-Quality Connection: What 14,703 Facilities Tell Us

How much does staffing really matter? We analyzed CMS data from all 14,703 rated nursing facilities in the United States to find out. The results are unambiguous: staffing levels are the single strongest predictor of facility quality, and the gap between top-rated and bottom-rated facilities is wider than most operators realize.

The Numbers: Staffing by Star Rating

SilverOcean's analysis of 14,703 facilities from March 2026 CMS data reveals a clear, linear relationship between staffing and quality:

Star Rating	Nursing Hrs/Day	RN Hrs/Day	Staff Turnover	Facilities
1 Star	3.53	0.51	54.5%	2,938
2 Stars	3.69	0.58	49.1%	3,066
3 Stars	3.82	0.64	46.5%	2,819
4 Stars	3.98	0.71	43.6%	2,807
5 Stars	4.40	0.95	38.6%	2,942

Five-star facilities provide 25% more total nursing hours per resident per day than one-star facilities (4.40 vs. 3.53). That difference translates to roughly 52 additional minutes of care per resident every single day.

RN Hours: The Multiplier Effect

While total nursing hours matter, the data shows that registered nurse hours matter even more. Five-star facilities average 0.95 RN hours per resident per day, compared to just 0.51 at one-star facilities. That is nearly double the RN presence.

This makes intuitive sense. RNs are the clinicians who catch early warning signs, coordinate care plans, and make the judgment calls that prevent adverse events. When you cut RN coverage, you are not just reducing a staffing metric - you are removing the clinical expertise that keeps residents safe.

The 3.8-Hour Threshold

According to CMS data analyzed by SilverOcean, there appears to be a meaningful threshold around 3.8 total nursing hours per resident per day. Facilities below this level cluster in the one- to two-star range. Facilities above it begin to separate into three-, four-, and five-star territory.

This aligns with CMS's own staffing recommendations and suggests that operators seeking to improve their ratings should target at minimum 3.8 hours of total nursing care per resident day as a baseline, with 4.0 or above needed to compete for top ratings.

Turnover: The Silent Quality Killer

Perhaps the most striking finding in the data is the turnover gap. One-star facilities average 54.5% annual staff turnover. Five-star facilities average 38.6%. That is a 16-percentage-point spread, and its implications are enormous.

High turnover means residents are constantly being cared for by people who do not know them. New staff miss subtle changes in condition. Institutional knowledge walks out the door. Training costs consume budgets that could go toward direct care. And the remaining staff, stretched thin by vacancies, burn out faster, creating a vicious cycle.

Reducing turnover from 54% to 39% does not happen by accident. It requires intentional investment in workplace culture, competitive compensation, manageable workloads, and tools that reduce administrative burden on frontline staff.

What This Means for Operators

The data tells a clear story: quality is not random. It is built through deliberate staffing decisions. Here is how to benchmark your facility against the national data:

If your total nursing hours are below 3.53 per resident day, you are operating below even the one-star average. Immediate action is needed.

If your RN hours are below 0.64, you are below the three-star midpoint. Increasing RN coverage should be a priority.

If your turnover exceeds 49%, you are in the bottom 40% of all facilities nationally. Retention programs should be a strategic focus.

The path from a one-star to a three-star rating is not mysterious. According to SilverOcean's analysis of 14,703 facilities, it requires roughly 0.3 additional nursing hours per resident per day, 0.13 more RN hours, and an 8-percentage-point reduction in turnover. Those are achievable targets with the right strategy and the right tools to support your workforce.

The facilities that understand this connection between staffing investment and quality outcomes are the ones moving up in the ratings. The data leaves no room for doubt.
