★★☆☆☆2 out of 5 StarsWhy 2 stars?Umass Memorial Healthalliance Hospitals's 2-star rating reflects above-average performance on Safety of Care and below-average performance on Readmissions, Patient Experience, and Timely Care.
CMS Overall Hospital Quality Star Rating · Umass Memorial Healthalliance Hospitals
How was Umass Memorial Healthalliance Hospitals's 2-star rating calculated?
The CMS Overall Hospital Quality Star Rating applies to
acute care hospitals like Umass Memorial Healthalliance Hospitals. 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.
Measures the rate at which patients die within 30 days of hospital admission for specific conditions. A lower mortality rate indicates better outcomes.

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

Psychiatric Unit Quality (IPFQR)
Umass Memorial Healthalliance Hospitals operates a Medicare-certified inpatient psychiatric unit that reports under the federal IPFQR program. The measures below are specific to that unit — not the hospital as a whole. 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.
Physical Restraint Use 0.1 hours per 1,000 patient-hours
National median: 0.1 hours Near national median
HBIPS-2 — hours of physical restraint use per 1,000 patient-hours. Lower is better; restraints carry physical and psychological risks.
Seclusion Use 0.0 hours per 1,000 patient-hours
National median: 0.0 hours Near national median
HBIPS-3 — hours of seclusion per 1,000 patient-hours. Lower is better; seclusion is used only when no other intervention works.
Metabolic Screening (SMD) 91.0 %
National median: 92.0 % Near national median
SMD — % of patients on antipsychotics screened for metabolic side effects (BMI, blood glucose, cholesterol). Antipsychotics raise metabolic-syndrome risk; screening catches it early.
Transition Record Completed 94.0 %
National median: 77.0 % Better than national median
TR-1 — % of discharges with a completed transition record including medications, follow-up plan, and crisis instructions.
Follow-up Within 7 Days 38.6 %
National median: 35.4 % Near national median
FAPH-7 — % of patients with a follow-up outpatient mental-health visit within 7 days of discharge. Predicts lower readmission risk.
Follow-up Within 30 Days 63.6 %
National median: 60.7 % Near national median
FAPH-30 — % of patients with a follow-up outpatient mental-health visit within 30 days of discharge.
30-Day Readmission Rate 17.6 %
National median: 19.1 % Near national median
READM-30-IPF — risk-standardized 30-day readmission rate. No Different Than the National Rate
Influenza Immunization 82.0 %
National median: 87.0 % Near national median
IMM-2 — % of patients given a flu vaccine during the inpatient stay.

Medicare quality scoring (MIPS)
391 of these clinicians have a published
Merit-based Incentive Payment System (MIPS) final score.
Of those, 377
(96%) 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.
