This pathologically assessed for cancer involvement. Assessing operation became the only therapy for breast cancer, if the SLN demonstrated metastasis could potentially allow but was fraught with long-term physical limitations and the remaining ALN to forego removal, thus minimizing the sequala. By the mid-20th century, physicians developed risks for lymphedema and neurological dysfunction of the a better understanding of the pathophysiology of breast upper extremity. cancer.

More recently, thoracic endovascular aneurysm angiography (CTA). If a coronary etiology is ruled out in repair (TEVAR) devices made endovascular or hybrid a patient presenting with chest pain, a CTA can quickly approaches feasible.

In continues to evolve to make treatment safer and more other instances, an aortic dissection is diagnosed when a tolerable to larger subsets of patients. CT scan is performed for a different clinical concern, such as a pulmonary embolism. Additional useful modalities In addition to conventional covered TEVAR devices, a in the diagnosis of TBAD include transesophageal novel system has recently become available.4 This approach echocardiography (TEE), magnetic resonance angiography involves a combination of covered and uncovered stents (MRA), intravascular ultrasound (IVUS), and catheter allowing treatment of the central aorta by re-expanding angiography.

In more complex versions of this type of problem solving, our efforts at invention have resulted in grant funding, abstract presentation, and manuscript publication in various societies and medical journals across the globe. Dr. Gwen Lomberk’s Division of Research in the Department of Surgery is a virtual assembly line of good ideas that are on their way to changing medical practice. But it is the second variable in the equation that is often overlooked in an academic medical institution. Medical school curricula generally don’t include topics like market segmentation, customer acquisition costs and development of a value proposition. Even in the rare cases in which genius and life experience have bestowed upon an individual the gifts of entrepreneurship (we’re looking at you, Drs. Mike and Aoy Mitchell), success requires the assembly of a team. This past year I (Dr. David Joyce) had the opportunity to assemble a diverse group of business executives and technology partners to compete in the University of Chicago Booth School of Business/
Polsky Center’s Global New Venture Challenge. Mentored by some of the best economists in the startup world, we developed a strategy to use the data from wearable devices to train an artificial intelligence algorithm that could predict adverse events such as early hospital readmission in heart failure patients. Our team was selected to compete against cohorts from London and Hong Kong in the final round of competition later this spring, and with a little luck and some traction with a Venture Capital firm, we hope to launch this product by the end of the year. Throughout this process, we couldn’t help imagining what might happen if everyone in our department had the same opportunity to partner with a team that offered such diverse talents. Professor Frederick Terman was considered the “Father of Silicon Valley” because he encouraged engineering students like William Hewlett and David Packard to not just develop good ideas, but to commercialize them.

Report Discussion NSQIP data allows us to take the complexity of our patients and procedures into account as we determine where we need to focus our quality improvement efforts. When an opportunity is identified, the NSQIP database allows us to quickly determine specific patients in each model to experience a complication of interest in order to conduct a more detailed analysis. Outcome-Specific Heat Maps are another tool that allows us to focus QI efforts. This provides participants with a visual overview of their performance. Adjusted percentiles are used to determine the fill/pattern for a particular Figure 2- General/Vascular surgery outcomes. model category and height is proportional to the overall case volume submitted by the hospital. Hovering over a model category displays additional model summary information. An example of an Outcome- Specific Heat Map is provided in Figure 3. One drawback of the semi-annual report is that cases performed up to 18 months previously are included and the most recent cases were performed 6 months previously. NSQIP provides an on demand, risk-adjusted and smoothed rates report for the different models as well. This allows for real time tracking of outcomes in order to track the impact of QI interventions and to monitor evolving issues. Figure 3 – NSQIP Outcome Specific Heatmap. We use NSQIP for many other purposes factors and trends in rare events, and for our researchers as well.
