CMS Overall Hospital Quality Star Rating · Ascension Saint Joseph - Chicago

How was Ascension Saint Joseph - Chicago's 4-star rating calculated?

The CMS Overall Hospital Quality Star Rating applies to acute care hospitals like Ascension Saint Joseph - Chicago. 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 Ascension Saint Joseph - Chicago'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% 16 of 19 1 better 15 same 0 worse
Readmissions 22% 5 of 6 1 better 4 same 0 worse
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.

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.

Patient Experience

Same as National Average

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 Ascension'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 75%
  • Communication with Doctors 78%
  • Hospital Cleanliness 68%
  • Hospital Quietness 58%
  • Staff Responsiveness N/A
  • Discharge Information 85%
  • Overall Hospital Rating (9 or 10) 65%
  • Would Recommend Hospital 69%

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

Psychiatric Unit Quality (IPFQR)

Ascension Saint Joseph - Chicago 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.

Metabolic Screening (SMD) 100.0 %
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.

SUB-2 — % of patients with alcohol/drug use referred for treatment during admission.

Transition Record Completed 0.0 %

Medicare quality scoring (MIPS)

61 of these clinicians have a published Merit-based Incentive Payment System (MIPS) final score. Of those, 29 (48%) 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.

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.
