How to Read Nursing-Home Ratings

When you are comparing nursing homes, especially under the stress of a hospital discharge or a sudden decline, the star ratings on Medicare's website feel like a lifeline. A quick way to see which homes are good and which to avoid. The ratings genuinely are useful. But they work best when you understand exactly what they do and do not measure, so you can read them with clear eyes instead of treating a single number as the final word.

This guide walks through Medicare's five-star rating system on the Care Compare tool: what the overall star is built from, what each of the three underlying ratings means, where the system falls short, and how to look for the one thing the ratings cannot tell you, whether a home will treat an LGBTQIA+ elder with respect.

What is Medicare Care Compare?

Care Compare is a free, official tool on Medicare.gov that lets anyone look up nursing homes that are certified by Medicare or Medicaid. For each home, it publishes an overall quality rating from one to five stars, where one star means much below average and five stars means much above average compared with other nursing homes.

That overall star is not a single measurement. According to the Centers for Medicare & Medicaid Services, it is assembled from three separate ratings: health inspections, staffing, and quality measures. Each of those has its own star rating too, and reading them individually tells you far more than the overall number alone. A home could earn four stars overall while hiding a weak spot in one area that matters to your family.

What do the three ratings measure?

The three components each look at a different slice of a home's performance. Here is what each one captures.

Rating	What it is based on	Why it matters
Health inspections	Findings from on-site state inspection surveys over roughly the past three years	Reflects real safety and care problems inspectors actually found
Staffing	How many nurses and aides are available per resident, including registered nurse time	More staff generally means more attention and faster help
Quality measures	Clinical data on residents, such as falls, pressure sores and mobility	Shows measured outcomes for the people who live there

The health inspection rating is the backbone. CMS builds the overall star by starting with the health inspection rating, then adding a star if staffing is strong and subtracting one if staffing is very weak, before factoring in quality measures. That is why two homes with the same overall star can feel very different, and why it pays to open up all three ratings rather than stopping at the summary.

How much should I trust the stars?

Treat the ratings as a strong starting point, not a verdict. They are genuinely helpful for narrowing a long list down to a few candidates and for spotting homes with a troubling inspection record. A one-star health inspection rating is a real warning worth taking seriously.

But the system has known limits. Some of the quality-measure data is self-reported by the homes themselves, which means it can be less reliable than the on-site inspection findings. The ratings are also comparative, graded on a curve against other homes, so a five-star home is above average but not automatically perfect. And the numbers describe past performance, which can lag behind a recent change in ownership, management or staffing. None of this means you should ignore the ratings. It means you should pair them with your own eyes. A visit, a conversation with staff and current families, and our checklist for touring a senior community will tell you things no dataset can.

What warning signs sit beneath the stars?

A few details are worth digging for even when the overall star looks reassuring. CMS flags a small number of homes with a persistent record of serious problems as Special Focus Facilities, and it also publishes a longer list of candidates being watched for the program. If a home you are considering appears on either list, treat that as a much louder warning than a single low star, and ask the home directly what has changed.

Two more habits help. Check the date of the most recent health inspection, because a rating built on a survey from years ago may not reflect a recent change in ownership or leadership. And look at whether the home has had complaint inspections, which are triggered by a specific concern rather than the routine cycle, since a cluster of them can point to problems that a periodic survey missed. Care Compare lets you open the actual inspection reports, and the specific deficiencies listed there, such as medication errors or infection-control lapses, tell you far more than the star that summarizes them.

What do the ratings leave out?

The biggest gap, for the families we serve, is that Medicare's ratings say nothing about whether a home is welcoming to LGBTQIA+ residents. The five-star system measures clinical quality, safety and staffing. It does not measure whether staff will use a resident's correct name and pronouns, whether a same-sex spouse will be treated as family, or whether an older transgender adult will be cared for with dignity. A home can earn five stars and still be a cold or unsafe place for an LGBTQIA+ elder to be fully themselves.

So you have to ask about that separately. Look for outside signals the ratings do not capture, such as staff who have completed SAGECare cultural competency training, a clear written nondiscrimination policy, and participation in accountability efforts like the Long-Term Care Equality Index. It is also worth understanding the difference between a home that is merely friendly versus one that is genuinely affirming, because the ratings will not tell you which one you are looking at.

How do I put it all together?

Use the ratings the way they are meant to be used: as a filter, not a decision. Start on Care Compare and read all three ratings for each home, not just the overall star, paying close attention to the health inspection and staffing ratings. Set aside homes with serious inspection problems. Then take your shortlist into the real world.

Visit each remaining home in person, more than once if you can. Watch how staff interact with residents, ask current families about their experience, and ask the home directly how it welcomes LGBTQIA+ residents and their chosen families. Bring our list of questions to ask before moving in and watch for contract red flags. When you combine the data with what you learn on the ground, and search our directory for affirming options, you will make a far more confident choice than the stars alone could ever give you.
