Understanding Hospital Ratings for Select Clinical Quality: Basic Explanation
Ribbons and pies represent data that hospitals reported for discharges between January 1st, 2009 and December 31st, 2009.
The Maine Health Management Coalition awards pies and ribbons to hospitals that meet certain standards for quality care. Pies and ribbons are awarded in four areas:
- Heart attack (AMI)
- Heart failure (CHF)
- Pneumonia (PNE)
- Surgical care (SCIP)
Starting August 2009, the hospital rating system awards 2 different color ribbons – blue ribbons and blue ribbons with a gold inlay for meeting certain standards of care. These ratings are explained below.
The MHMC gets each hospital’s performance information from the Northeast Health Care Quality Foundation (NHCQF), Maine’s Quality Improvement Organization (QIO). Data is collected and submitted by the hospital every quarter.
The hospital’s performance rate shows the percent of the time that its patients got all of the care they needed. Hospital performance is based on the Appropriate Care Measure (ACM), which is the percent of patients that received ALL the care they were qualified to receive – the right care for every patient every time. This is also known as the “perfect care” measure and is thought to be the most meaningful for patients.
Pies are determined by comparing a hospital’s performance to how other hospitals around the country perform.
| What Pie Looks Like | What it is Called | What Pie Rating Means |
![]() |
One-quarter (¼) pie | Lower than U.S. average |
![]() |
Half (½) pie | No different than U.S. average |
![]() |
Three-quarter (¾) pie | Higher than U.S. average |
![]() |
Full pie | Equal to or better than the top hospitals |
![]() |
Unable to Determine | No pie, or “unable to determine” is not a reflection of performance. It means that we are unable to evaluate the correct score for statistical reasons (the hospital’s confidence interval spans both the national 50th and 90th percentiles). |
Ribbons are then awarded based on the pies:
| What Ribbon Looks like | What it is Called | What Ribbon Rating Means |
| Blue ribbon with gold seal inlay | Best choice | |
| Blue ribbon | Better choice | |
| No ribbon | Performance is below U.S. average | |
| Unable to Determine | For those we are unable to evaluate |

Understanding Hospital Ratings for Select Clinical Quality: Advanced Explanation
See below for more details about the Select Clinical Quality Ratings.
Process of Care:
Clinical quality facts are collected from hospitals’ patient records. The data is changed to rates that measure:
- How well the hospitals care for their patients
- The percentage of times that a patient received all of the care that they needed to result in a better outcome
The measures reported are:
| MEASURE NAME |
| Heart Attack Patients Given ACE Inhibitor or ARB for Left Ventricular Systolic Dysfunction (LVSD) |
| Heart Attack Patients Given Aspirin at Arrival |
| Heart Attack Patients Given Aspirin at Discharge |
| Heart Attack Patients Given Beta Blocker at Discharge |
| Heart Attack Patients Given Smoking Cessation Advice/Counseling |
| Heart Failure Patients Given ACE Inhibitor or ARB for Left Ventricular Systolic Dysfunction (LVSD) |
| Heart Failure Patients Given an Evaluation of Left Ventricular Systolic (LVS) Function |
| Heart Failure Patients Given Discharge Instructions |
| Heart Failure Patients Given Smoking Cessation Advice/Counseling |
| Pneumonia Patients Assessed and Given Pneumococcal Vaccination |
| Pneumonia Patients with Blood Culture Before First Antibiotic |
| Pneumonia Patients Given Initial Antibiotic(s) within 6 Hours After Arrival |
| Pneumonia Patients Given Smoking Cessation Advice/Counseling |
| Pneumonia Patients Given the Most Appropriate Initial Antibiotic(s) |
| Pneumonia Patients Assessed and Given Influenza Vaccination |
| Surgery patients who were given an antibiotic at the right time (within one hour before surgery) to help prevent infection |
| Surgery patients whose preventive antibiotics were stopped at the right time (within 24 hours after surgery) |
| Surgery patients who were given the right kind of antibiotic to help prevent infection |
| Cardiac surgery patients with controlled blood glucose |
| Surgery patients with appropriate hair removal |
| Patients who got treatment at the right time (within 24 hours before or after their surgery) to help prevent blood clots after certain types of surgery |
| Surgery patients whose doctors ordered treatments to prevent blood clots after certain types of surgeries |
How Does MHMC Turn the Facts Into Ratings?
It is not easy to turn each patient interaction into a quality rating, but below are some examples of how it is done.
Example A:
Each heart failure patient needs four things done
All 100 patients have all four things done
Hospital A receives a performance score of 100% for heart failure because it provided all of the care for every patient every time
Example B:
Each heart failure patient needs four things done
Eighty of the 100 patients receive all four things they need. Ten of the patients receive only 3 of the 4 things, and the other ten receive only 2 of the 4 things
Hospital B receives a performance score of 80% for heart failure because it provided all of the care for only eighty of the 100 patients (80/100=80%) every time
Turning Data into Pies for Clinical Care Categories:
Pies are determined by comparing a hospital’s performance to how other hospitals around the country perform. More specifically, pies are based on how the hospital compares to the national average (national 50th percentile) and to the top performers (national 90th percentile).
The absolute performance is not used for comparison (for example the 100% or 80% from examples A & B above) but, rather, what is called the confidence interval.
It is easier to be sure that something will happen again if you are basing your decision on a large sample size versus a small sample.
Example A:
The MHMC considers that some hospitals have more patients and others fewer patients before awarding pies and ribbons. The QIO determines a confidence interval for each hospital based on the number of patients each hospital sees. Hospitals can earn pies as follows:
| What Pie Looks Like | What it is Called | What Pie Rating Means | More Detail |
![]() |
Unable to Determine | No pie, or unable to determine, is not a reflection of performance. It means that we are unable to evaluate the correct score for statistical reasons (hospital confidence interval that spans both the national 50th and 90th percentiles). | |
![]() |
One-quarter (¼) pie | Lower than U.S. average | If a hospital’s confidence interval falls below the 50th percentile performance of all hospitals that report nation-wide, that hospital receives a ¼ pie. |
![]() |
Half (½) pie | No different than U.S. average | If a hospital’s confidence interval spans the 50th percentile, they receive ½ pie. |
![]() |
Three-quarter (¾) pie | Higher than U.S. average | If a hospital’s confidence interval is between the 50th and the 90th percentile performance, they are awarded a ¾ pie. |
![]() |
Full pie | Equal to or better than the top hospitals | If a hospital’s confidence interval is at or above the 90th percentile performance, they are awarded a full pie. |
Turning Data into Ribbons for Clinical Care Categories:
Once the pies are determined, ribbons are awarded as follows:
