This participant group is associated with the following hospital(s):

NOTE: Results are based on a participant’s unique group of patients (known as case mix) and the number of surgical procedures in each category. Results and star ratings below are specific to the participant listed and are not intended for direct comparison to other participants.

This Adult Cardiac Surgery Database (ACSD) participant’s score is shown as both a number and a vertical black line in each graph below. Following the participant’s score, the numbers in parentheses – (##, ##) – represent the range (known as a credible interval) within which the participant’s score was likely to fall. Determined using a statistical formula, each participant has a different range. Ranges are based on the participant’s unique mix of patients and number of surgical procedures in each category. The graphs also show the STS average score (the vertical red line) and the lowest-to-highest range across all North American ACSD participants. Hover over each graph for specific descriptions.

Using a statistical formula, participants receive star ratings based on their scores and how they compare to the STS average: 

1 stars
Worse Than Expected
If the participant's score and range is lower than the STS average score, the participant receives 1 star.
2 stars
As Expected
If the STS average score falls within the participant's range, the participant receives 2 stars.
3 stars
Better Than Expected
If the participant's score and range is higher than the STS average score, the participant receives 3 stars.

The majority of ACSD participants receive a 2-star (“as-expected”) rating. In comparison, far fewer participants receive 1-star (“worse than expected”) or 3-star (“better than expected”) ratings. In general, a 2-star or 3-star rating is consistent with good or excellent performance.

MVRR Composite Quality Rating (July 2020 - June 2023)

MVR MSG 1

Participant is not enrolled in public reporting for MVRR but does publicly report for at least one other procedure.

MVRR+CABG Composite Quality Rating (July 2020 - June 2023)

MVR+CABG MSG 1

Participant is not enrolled in public reporting for MVRR+CABG but does publicly report for at least one other procedure.

CABG Overall Composite Score is calculated using a combination of 11 quality measures divided into four categories or domains:

  1. Absence of Operative Mortality: Percentage of patients [risk-adjusted] who did not experience operative mortality.  Operative mortality is defined as death during the same hospitalization as surgery or after discharge but within 30 days of the procedure.
  2. Absence of Major Morbidity: Percentage of patients [risk-adjusted] who did not experience any major morbidity. These are: 1) reoperation for any cardiac reason (NQF definition); 2) renal failure; 3) deep sternal wound infection; 4) prolonged ventilation/intubation; 5) cerebrovascular accident/permanent stroke.
  3. Use of Internal Mammary Artery: Percentage of first-time CABG patients who received at least one IMA graft.
  4. Receipt of Required Perioperative Medications: Percentage of patients who received all required perioperative medications. Performance on perioperative medications is based on a combination of four NQF-endorsed process measures that relate to pre- and postoperative medication usage. The four medication measures are: 1) preoperative beta blockade therapy; 2) discharge anti-platelet medication; 3) discharge beta blockade therapy; and 4) discharge anti-lipid medication.

The Overall Composite Score represents the four domain scores in a single number.

AVR Overall Composite Score; AVR+CABG Overall Composite Score; MVRR Overall Composite Score; and MVRR+CABG Overall Composite Score represent two domain scores in a single number:

  1. Absence of Operative Mortality: Percentage of patients [risk-adjusted] who did not experience operative mortality.  Operative mortality is defined as death during the same hospitalization as surgery or after discharge but within 30 days of the procedure.
  2. Absence of Major Morbidity: Percentage of patients [risk-adjusted] who did not experience any major morbidity. These are: 1) reoperation for any cardiac reason (NQF definition); 2) renal failure; 3) deep sternal wound infection; 4) prolonged ventilation/intubation; 5) cerebrovascular accident/permanent stroke.
