Frequently Asked Questions

What is an acute care hospital?▼
Acute care hospitals treat patients with serious illnesses or injuries that require immediate, short-term care. Most general hospitals fall into this category.
What does the CMS star rating mean?▼
CMS rates hospitals on a 1–5 star scale based on five quality groups: mortality, safety, readmissions, patient experience, and timely care. Higher stars mean better performance across these measures.
Is a higher star rating always better?▼
Generally yes, but consider your specific needs. A 3-star hospital might excel in cardiac care while scoring lower in other areas. Look at individual metrics relevant to your procedure.
How often is this data updated?▼
CMS updates hospital quality data quarterly (January, April, July, October). Overall star ratings are updated annually, usually in August.
What is HCAHPS?▼
HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) is a standardized patient satisfaction survey administered to random samples of hospital patients. Results reflect real patient experiences.
How do I read the infection rates?▼
Infection rates are shown as Standardized Infection Ratios (SIR). A SIR below 1.0 means fewer infections than nationally expected. A SIR of 0.5 means the hospital has half the expected infection rate — significantly better.
Does a lower star rating mean the hospital is unsafe?▼
Not necessarily. Lower-rated hospitals often serve sicker, more complex patient populations that make outcomes harder to achieve. Consider the full picture and consult your doctor.
Are there other hospitals in BOSTON?▼
Yes — there are 11 other hospitals in BOSTON, MA in the CMS database. Compare all hospitals in BOSTON to find the best fit for your care needs.
