Bronson Cardiothoracic, Vascular and Endovascular Surgery Specialists

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 are 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 are 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+CABG Composite Quality Rating (January 2023 - December 2025)

MVR+CABG MSG 2

Participant is enrolled in public reporting for MVRR+CABG but did not receive composite measure results for this timeframe.

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

  1. Absence of Operative Mortality: Proportion of patients [risk-adjusted] who do 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 and includes patients discharged to hospice.
  2. Absence of Major Morbidity: Proportion of patients [risk-adjusted] who do not experience any major morbidity. Major morbidity is defined as having at least one of the following adverse outcomes: 1) reoperations for any cardiac reason; 2) renal failure; 3) deep sternal wound infection; 4) prolonged ventilation/intubation*; 5) cerebrovascular accident/permanent stroke.
  3. Use of Internal Mammary Artery (IMA): Proportion of first-time CABG patients who receive at least one IMA graft. Note: Patients with prior CABG surgery or with documented contraindication for IMA use (subclavian stenosis, previous cardiac or thoracic surgery, previous mediastinal radiation, an emergent or salvage procedure, no LAD disease, or other acceptable STS provided exclusion) are not included in the denominator.
  4. Use of All Evidence-based Perioperative Medications: Proportion of patients who receive all required perioperative medications. The required perioperative medications are: 1) preoperative beta blockade therapy; 2) discharge anti-platelet medication; 3) discharge beta blockade therapy; and 4) discharge anti-lipid medication. Note: the discharge medications were not required for patients who died prior to discharge.

*Prolonged ventilation is defined as ventilation exceeding 24 hours in the postoperative period. This time includes hours from OR exit until extubation, plus any additional hours following reintubation.

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: Proportion of patients [risk-adjusted] who do 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 and includes patients discharged to hospice
  2. Absence of Major Morbidity: Proportion of patients [risk-adjusted] who do not experience any major morbidity. Major morbidity is defined as having at least one of the following adverse outcomes: 1) reoperations for any cardiac reason; 2) renal failure; 3) deep sternal wound infection; 4) prolonged ventilation/intubation*; 5) cerebrovascular accident/permanent stroke. 

*Prolonged ventilation is defined as ventilation exceeding 24 hours in the postoperative period. This time includes hours from OR exit until extubation, plus any additional hours following reintubation.
