This Participant Surgery Group is associated with the following hospital(s):

Trinity Health Ann Arbor Hospital — Ann Arbor, MI

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 below are specific to the participant listed and are not intended for direct comparison to other participants.

This General Thoracic Surgery Database (GTSD) 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 GTSD 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. The majority of GTSD participants perform As Expected.

In comparison, far fewer GTSD participants perform Worse Than Expected or Better Than Expected. In general, an As Expected or Better Than Expected rating is consistent with good or excellent performance.

Worse Than Expected

Participant’s score and range are lower than the STS average score.

As Expected

The STS average score falls within the participant’s range.

Better Than Expected

Participant’s score and range are higher than the STS average score.

Performance for Resection for Primary Lung Cancer Compared to STS and National Outcomes*

* These NIS data are the most recent data available at this time. There are more resection for primary lung cancer patients in a single year of NIS data than in the GTSD, so a decision was made to use 3 years of STS GTSD data.

Resection for Primary Lung Cancer Overall Composite Score represents two domain scores in a single number:

Absence of Operative Mortality: Proportion of primary lung cancer resection (i.e., wedge resection, segmentectomy, lobectomy, sleeve lobectomy, bilobectomy, pneumonectomy) patients [risk-adjusted] who do not experience operative mortality. Operative mortality is defined as hospital death, death within 30 days of surgery, or discharge to hospice.
Absence of Major Morbidity: Proportion of primary lung cancer resection (i.e., wedge resection, segmentectomy, lobectomy, sleeve lobectomy, bilobectomy, pneumonectomy) patients [risk-adjusted] who do not experience any major morbidity. Major morbidity is defined as the presence of any of the following postoperative conditions: tracheostomy, respiratory failure/reintubation, initial ventilatory support>48 hours, ARDS, bronchopleural fistula, pulmonary embolus, pneumonia, unexpected return to OR, myocardial infarct.

Esophagectomy for Esophageal Cancer Composite Score represents two domain scores in a single number:

Absence of Operative Mortality: Proportion of patients [risk-adjusted] who did not experience operative mortality. Operative mortality is defined as death during the same hospitalization as surgery, death within 30 days of surgery, or discharge to hospice.
Absence of Major Morbidity: Proportion of patients [risk-adjusted] who did not experience any major complication. These are: 1) unexpected return to the operating room; 2) anastomotic leak requiring medical treatment only (Type 1 and Type 2); 3) respiratory failure/reintubation; 4) initial ventilator support >48 hours; 5) pneumonia; 6) new renal failure per RIFLE criteria; 7) recurrent laryngeal nerve paresis.
