CMS Overall Hospital Quality Star Rating · St John's Episcopal Hospital at South Shore
How was St John's Episcopal Hospital at South Shore's 1-star rating calculated?
The CMS Overall Hospital Quality Star Rating applies to
acute care hospitals like St John's Episcopal Hospital at South Shore. CMS standardizes
every underlying measure against the national rate, computes
a weighted score for each of five domains, sums them by the
fixed weights below, and assigns 1–5 stars using k-means
clustering across all reporting hospitals.

How star meaning varies by hospital type.
This CMS Overall Star Rating only applies to acute care
hospitals. Children's hospitals (Pediatric Quality), psychiatric
hospitals (IPFQR), inpatient rehabilitation facilities (IRF QRP),
long-term acute care hospitals (LTACH QRP), and VA medical centers
each use separate quality programs designed for their patient
populations. Comparing star ratings across these facility types
isn't meaningful — see the methodology page for the full mapping
of which program applies to which facility.

They cover restraint and seclusion use, screening for medication side effects, substance-use and tobacco treatment, transitions of care, follow-up after discharge, and readmissions.
Show the psychiatric unit's 10 reported measures expand ↓
Physical Restraint Use 0.0 hours per 1,000 patient-hours
National median: 0.1 hours Near national median

Medicare quality scoring (MIPS)
119 of these clinicians have a published
Merit-based Incentive Payment System (MIPS) final score.
Of those, 37
(31%) score above the national median of 85.5.
MIPS scoring is heavily compressed at the top of the 0–100 range, so individual scores
are not a reliable consumer signal. We surface roster-level coverage and the share
above the national median instead.

How nearby comparisons work
Quality and ratings data are sourced from the U.S. Centers for
Medicare & Medicaid Services (CMS) Hospital Compare program.
Star ratings are CMS's own calculation; CareRanks does not modify
or re-weight them. Facility-level details (address, beds,
ownership, teaching status) come from CMS provider files and the
CMS Provider of Services file.
Pricing data, where shown, is drawn from the hospital's own
Machine-Readable File (MRF) published under the federal Hospital
Price Transparency Rule. See our methodology for the full update
cadence and limitations.
