Ontario, California's San Bernardino County seat, has 4 Medicare-certified nursing homes with approximately 393 beds. Families have good options, with many facilities exceeding state averages.

Ontario vs. California: Above Average Quality

Ontario nursing homes outperform the state average on key quality metrics. The city's average CMS rating of 3.75 stars exceeds California's statewide average of 3.15 stars by 0.6 stars—a meaningful difference that suggests stronger local standards.

2 of 4 facilities earn a B grade or better, giving families good options. While quality is generally high, the overall picture is positive for Ontario families.

Understanding Our Trust Score System

The Trust Score is a 0-100 rating calculated from CMS's official nursing home database. The score combines five data categories:

• Health Inspection Results — Recent deficiencies, their severity, and patterns over time
• Staffing Levels — RN hours, total nursing hours, and weekend staffing
• Quality Measures — Clinical outcomes like falls, pressure ulcers, and rehospitalizations
• Penalties — Fines, payment denials, and enforcement actions
• Complaints — Substantiated complaints and their severity

In Ontario, 2 facilities score a B grade or better, indicating they meet quality benchmarks across these categories. We recommend families prioritize these facilities and carefully research any facility rated C or below before visiting.

Staffing: A Significant Concern in Ontario

Staffing levels are among the most important predictors of nursing home quality. Research consistently shows that facilities with more nursing staff—especially registered nurses—have better outcomes for residents.

Ontario facilities average 0.37 RN hours per resident day, which falls below the CMS-recommended threshold of 0.75 hours. The typical Ontario resident receives approximately 22 minutes of RN attention daily—compared to the 45 minutes experts recommend.

1 Ontario facilities exceed CMS staffing recommendations. Families prioritizing staffing should look for facilities with the "Top Staffing" badge and ask specifically about RN hours during facility visits.

Ownership: Mix of For-Profit and Non-Profit

Ontario has 1 non-profit nursing homes and 3 for-profit facilities. 3 of 4 facilities are chain-owned, with the remainder independently operated.

Research suggests non-profit facilities often have higher staffing levels and fewer deficiencies on average, though ownership type alone does not guarantee quality. Families should evaluate each facility individually using inspection data, staffing levels, and recent deficiency reports.
