Choosing a hospital in Sonoma County

When comparing hospitals, examine the CMS overall rating along with the measure groups behind it, confirm the services you need are available, and check whether the hospital is in your insurance network. Ratings are signals, not medical advice.

The strongest comparisons weigh several signals together - inspection history, nurse staffing, quality measures, and the particular services someone requires. Ratings pull those signals into a single number, but they cannot stand in for a visit or a conversation with the staff.

Where you can, visit each option in Sonoma County, ask how care plans are created and revisited, and get costs, coverage, and availability confirmed in writing. Steady staffing and open communication with families count for as much as any published rating.
