★☆☆☆☆1 out of 5 StarsWhy 1 stars?North Shore Medical Center's 1-star rating reflects above-average performance on Safety of Care and below-average performance on Patient Experience and Timely Care.
CMS Overall Hospital Quality Star Rating · North Shore Medical Center
How was North Shore Medical Center's 1-star rating calculated?
The CMS Overall Hospital Quality Star Rating applies to
acute care hospitals like North Shore Medical Center. 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
Same as National Average
Measures how often patients return to the hospital within 30 days of discharge. Lower readmission rates suggest effective treatment and discharge planning.
Based on the HCAHPS survey — patient satisfaction with communication, cleanliness, pain management, and discharge information.

Medicare quality scoring (MIPS)
39 of these clinicians have a published
Merit-based Incentive Payment System (MIPS) final score.
Of those, 7
(18%) 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.

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.
