CMS Overall Hospital Quality Star Rating · Colleton Medical Center (Acute Care)

How was Colleton Medical Center (Acute Care)'s 2-star rating calculated?

The CMS Overall Hospital Quality Star Rating applies to acute care hospitals like Colleton Medical Center (Acute Care). 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 Colleton Medical Center (Acute Care)'s rating
Domain Weight Measures reported Hospital performance vs. national
Mortality 22% 5 of 7 0 better 5 same 0 worse
Safety of Care 22% 14 of 19 1 better 13 same 0 worse
Readmissions 22% 4 of 6 0 better 2 same 2 worse
Timely & Effective Care 12% 17 of 22 5 better 12 same 0 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.

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 Colleton'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 81%
  • Communication with Doctors 83%
  • Hospital Cleanliness 74%
  • Hospital Quietness 66%
  • Staff Responsiveness N/A
  • Discharge Information 85%

Psychiatric Unit Quality (IPFQR)

Colleton Medical Center (Acute Care) 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 0.3 hours per 1,000 patient-hours
National median: 0.1 hours Worse than 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 0.1 hours per 1,000 patient-hours
National median: 0.0 hours Worse than 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) 93.0 %
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 0.0 %
National median: 77.0 % Worse than national median

TR-1 — % of discharges with a completed transition record including medications, follow-up plan, and crisis instructions.

30-Day Readmission Rate 17.0 %
National median: 19.1 % Better than national median

READM-30-IPF — risk-standardized 30-day readmission rate. No Different Than the National Rate

Influenza Immunization 98.0 %
National median: 87.0 % Better than national median

IMM-2 — % of patients given a flu vaccine during the inpatient stay.

Medicare quality scoring (MIPS)

63 of these clinicians have a published Merit-based Incentive Payment System (MIPS) final score. Of those, 16 (25%) 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 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.
