CMS Overall Hospital Quality Star Rating · Medstar Saint Mary's Hospital

How was Medstar Saint Mary's Hospital's 4-star rating calculated?

The CMS Overall Hospital Quality Star Rating applies to acute care hospitals like Medstar Saint Mary's Hospital. 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.

Domains that fed Medstar Saint Mary's Hospital's rating
Domain	Weight	Measures reported	Hospital performance vs. national
Mortality	22%	6 of 7	0 better 6 same 0 worse
Safety of Care	22%	17 of 19	1 better 16 same 0 worse
Readmissions	22%	5 of 6	3 better 2 same 0 worse
Timely & Effective Care	12%	17 of 22	3 better 8 same 6 worse
Patient Experience	22%	HCAHPS	See HCAHPS detail below

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.

Medicare quality scoring (MIPS)

258 of these clinicians have a published Merit-based Incentive Payment System (MIPS) final score. Of those, 53 (21%) 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.

Source: CMS Doctors and Clinicians (Care Compare) national downloadable file and MIPS Performance Year final scores, as of 2026-05-27. Affiliations from the CMS Facility Affiliations dataset. About 16% of small facilities (critical access, rural emergency, freestanding psych, IRF/LTCH) do not appear in the affiliations file and therefore have no panel.

About this data

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.
