How the Hospital Compare overall rating is calculated:

The Hospital Compare overall rating summarizes up to 64 quality measures across seven areas of quality into a single star rating for each hospital. A hospital's overall rating is calculated using only those measures for which data are available. This may include as few as 9 or as many as 64 measures. The average is about 40 measures.

Hospitals report data to the Centers for Medicare & Medicaid Services through the Hospital Inpatient Quality Reporting (IQR) Program and the Hospital Outpatient Quality Reporting (OQR) Program.

The methodology uses a statistical model known as a latent variable model. Seven different latent variable models are used to calculate scores for seven groups of measures.

2.Safety of Care
4.Patient Experience
5.Effectiveness of Care
6.Timeliness of Care
7.Efficient Use of Medical Imaging

A hospital summary score is then calculated by taking the weighted average of these group scores. If a hospital is missing a measure category, the weights are redistributed amongst the qualifying measure categories.

Finally, the overall rating is calculated using the hospital summary score.

Only hospitals that have at least three measures within at least three measure groups or categories, including one outcome group (mortality, safety, or readmissions), are eligible for an overall rating. Not all hospitals report all measures. Therefore, some hospitals may not be eligible for an overall rating.

The comprehensive methodology report provides additional detail on the methodology used to calculate the Hospital Compare overall rating.
