CMS Overall Hospital Quality Star Rating · Guam Memorial Hospital Authority

How was Guam Memorial Hospital Authority's 2-star rating calculated?

The CMS Overall Hospital Quality Star Rating applies to acute care hospitals like Guam Memorial Hospital Authority. 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 Guam Memorial Hospital Authority'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% 0 of 19 Not reported
Readmissions 22% 0 of 6 Not reported
Timely & Effective Care 12% 8 of 22 1 better 3 same 4 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.

Quality measures

Mortality

Same as National Average

Measures the rate at which patients die within 30 days of hospital admission for specific conditions. A lower mortality rate indicates better outcomes.

Readmissions

Measures how often patients return to the hospital within 30 days of discharge. Lower readmission rates suggest effective treatment and discharge planning.

Patient Experience

Based on the HCAHPS survey — patient satisfaction with communication, cleanliness, pain management, and discharge information.

Patient survey detail — the questions feeding the Patient Experience domain above expand ↓

CMS computes the Patient Experience domain from the federal HCAHPS survey. Each bar below is one survey question; the percentage is the share of Guam's recent patients who gave the most positive response. HCAHPS percentages aren't directly comparable across all measures — see the methodology page for how CMS weights them.

  • Communication with Nurses N/A
  • Communication with Doctors N/A
  • Hospital Cleanliness N/A
  • Hospital Quietness N/A
  • Staff Responsiveness N/A
  • Discharge Information N/A
  • Overall Hospital Rating (9 or 10) N/A
  • Would Recommend Hospital N/A

Percentages represent patients who gave the most positive response. Survey conducted by CMS through the HCAHPS program.

Medicare quality scoring (MIPS)

77 of these clinicians have a published Merit-based Incentive Payment System (MIPS) final score. Of those, 63 (82%) 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 2026-07-18. 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.

Roster from CMS Doctors and Clinicians (Care Compare), updated 2026-07-18. A clinician may also practice at other facilities; "affiliated" means this hospital is on their CMS profile, not that they exclusively work here. Procedure volumes are Medicare fee-for-service counts from the CMS clinician utilization file (all practice locations, not just this hospital). Industry payment totals are from CMS Open Payments, program year 2024, and include meals, travel, consulting, and speaking fees; payments are legal and common — we show them for transparency, not as a quality judgment.

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.
