Understanding the Data
1. Quality Ratings
The quality ratings were created with the CMS Hospital Compare
analysis tool and are based on several health topics and conditions relating to:
(a) Patterns of Care - information about the numbers of surgeries or procedures that a hospital performs; and
(b) Results of Care - patient survey results about their experience in the hospital.
Click on the “Quality Ratings” tab to select a health condition or hospital(s) to view ratings.
Comparisons may be based on the national average for hospitals of the same type (profit or not for profit) and size (number of beds) or within a certain radius of user selected hospital(s). Results may be displayed as:
The hospital scored better than average
The hospital scored at average
The hospital scored below average
The hospital did not have enough data to report
Symbol and risk-adjusted rate. The risk –adjusted rate aims to 'level the playing field' by accounting for health risks that patients have before they enter the hospital.

2. Service Use Rates/Health Care Utilization
Service use rates tell how many patients use specific hospital services, how often and for how many days in a stay. Data is aggregated at hospital or county level. Discharge counts of less than six are suppressed and indicated with “c” to protect patient confidentiality.
Avoidable hospitalizations are a measure of primary care access or outpatient services in a community using hospital inpatient billing data.
Hospital discharge i.e., the hospital stay, is the unit of analysis, not a person or patient. Thus, a person who is admitted to the hospital multiple times in one year will be counted each time as a separate "discharge" from the hospital.
Length of stay is the number of days a person spends in the hospital during a stay.
Charges are what a hospital asks to be paid for services and do not include professional (doctor) fees. Costs are the actual value of these services. Costs are calculated utilizing cost-to-charge ratios based on hospital accounting reports from CMS.
Click on the “Service Use Rates” tab to select a health condition or surgical procedure to compare charges and cost among Connecticut hospitals and the rest of the nation.
