About COREWELL HEALTH WATERVLIET HOSPITAL

Hospital Type: Acute Care Hospitals
Ownership: Voluntary non-profit - Private
Emergency Services: Yes
CMS Certification Number: 230078

Acute care hospitals treat patients with serious, short-term medical conditions requiring immediate care. These are the most common type of hospital in the US.

Why doesn't this hospital have a CMS star rating?CMS only publishes an overall star rating when a hospital reports enough measures — at least three measures in at least three of the five measure groups, one of which must be mortality or safety of care. This hospital did not meet that threshold in the current data release. Not rated does not mean poor quality.

Patient Experience (HCAHPS Survey)

Based on standardized surveys sent to random patients after discharge

Mortality & Outcomes

30-day mortality rates — percentage of patients who died within 30 days of admission

Infection Control

Standardized Infection Ratio (SIR) — below 1.0 is better than the national benchmark

CLABSI Rate

N/A

Central line-associated bloodstream infection rate. A number below 1.0 means fewer infections than the national average — better than expected.

CAUTI Rate

N/A

Catheter-associated urinary tract infection rate. SIR below 1.0 = better than national benchmark. Important if you'll be in the ICU.

MRSA Rate

N/A

MRSA bloodstream infection rate. MRSA is a drug-resistant bacteria — an SIR below 1.0 means this hospital has fewer cases than expected nationally.

C. diff Rate

N/A

Clostridioides difficile (C. diff) infection rate. This gut bacteria can cause severe diarrhea — SIR below 1.0 is better than the national benchmark.

30-Day Readmission Rates

Lower readmission rates indicate better discharge planning and post-hospital care

Timely & Effective Care

How consistently this hospital follows proven care processes, compared with the US average

ER Median Visit Time

101 min

▲ Better than US average (157.08 min)

Median time patients spent in the emergency department from arrival until they left, excluding patients transferred to another facility or psychiatric patients. Across US hospitals the typical (median) time is about 2.5 hours.

Left Before Seen Rate

▲ Better than US average (1.68%)

Percentage of ER patients who left before being evaluated by a provider. Lower is better — a high rate suggests the ER is overcrowded or understaffed.

Staff Flu Vaccination Rate

80%

▲ Better than US average (74.5%)

Percentage of healthcare workers who received the influenza vaccine. Vaccinated staff protect vulnerable patients from flu transmission during hospitalization.

Medicare Payment Estimates

What Medicare pays this hospital for common procedures vs the national average

Medicare payment amounts are risk-adjusted averages. Actual patient costs depend on insurance plan, deductibles, and other factors.

Frequently Asked Questions

What is an acute care hospital?▼

Acute care hospitals treat patients with serious illnesses or injuries that require immediate, short-term care. Most general hospitals fall into this category.

What does the CMS star rating mean?▼

CMS rates hospitals on a 1–5 star scale based on five quality groups: mortality, safety, readmissions, patient experience, and timely care. Higher stars mean better performance across these measures.

Is a higher star rating always better?▼

Generally yes, but consider your specific needs. A 3-star hospital might excel in cardiac care while scoring lower in other areas. Look at individual metrics relevant to your procedure.

How often is this data updated?▼

CMS updates hospital quality data quarterly (January, April, July, October). Overall star ratings are updated annually, usually in August.

What is HCAHPS?▼

HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) is a standardized patient satisfaction survey administered to random samples of hospital patients. Results reflect real patient experiences.

How do I read the infection rates?▼

Infection rates are shown as Standardized Infection Ratios (SIR). A SIR below 1.0 means fewer infections than nationally expected. A SIR of 0.5 means the hospital has half the expected infection rate — significantly better.

Does a lower star rating mean the hospital is unsafe?▼

Not necessarily. Lower-rated hospitals often serve sicker, more complex patient populations that make outcomes harder to achieve. Consider the full picture and consult your doctor.
