Jack L. Paradise, MD, now retired, was the medical director of the Ambulatory Care Center at the Children’s Hospital of Pittsburgh. He was also a professor in the pediatrics department at the University of Pittsburgh School of Medicine. Dr. Paradise’s primary research was focused on indications for tonsillectomy and adenoidectomy, and on the diagnosis, management, and clinical significance of otitis media.
Why did you develop the Paradise Criteria? Was there a particular clinical experience or patient encounter that inspired you to create this tool for clinicians?
When in pediatric practice in a new, union-sponsored health plan in Appalachia, I was often called upon to render judgment as to whether or not tonsillectomy was indicated for individual children for whom a recommendation for tonsillectomy had been made by other physicians. This procedure was instituted because health plan administrators believed that tonsillectomy often was being performed on children without appropriate indications. Accordingly, payment for tonsillectomy by the health plan was made contingent on prior approval by me or by another member of a health-plan-designated group of consultants. In that role, I came to realize that there were then no evidence-based criteria for tonsillectomy. Recommendations by recognized authorities varied widely and were based entirely on clinical experience and/or opinion. When I left practice to head an ambulatory care program in a large teaching hospital, I saw an opportunity to address the question of criteria for tonsillectomy systematically.
Shannon N. Acker, MD, is a pediatric surgeon at the University of Colorado. Dr. Acker’s primary research is focused on trauma and surgical complications in adolescents.
Why did you develop the SIPA? Was there a particular clinical experience or patient encounter that inspired you to create this tool for clinicians?
Children have a remarkable ability to compensate for hypovolemic shock and are able to maintain a normal blood pressure until they reach cardiovascular collapse. Because shock index incorporates not only blood pressure but also heart rate, we hypothesized that an age adjusted shock index would help us to identify these children before the point of cardiovascular collapse. Our motivation to create SIPA came from an ongoing desire to improve pediatric trauma care and our desire to more accurately identify severely injured children prior to the point of cardiovascular collapse.

Andrew Shorr, MD, MPH, is an associate director of pulmonary and critical care medicine and the chief of the Pulmonary Clinic at MedStar Washington Hospital Center in Washington, DC. Dr. Shorr’s research interests include resistant pathogens and healthcare-associated bacteremia, and he has published more than 140 original studies.
Why did you develop the BAP-65 Score? Was there a particular clinical experience or patient encounter that inspired you to create this tool for clinicians?
I think we were interested in developing the score for two reasons: one, as a purely academic exercises, given that we have risk scores for PE and risk scores for pneumonia, clearly one of the pulmonary disease states where patients are sicker than they look is in COPD. So it was a clear hole in the range of pulmonary-critical care disease states that didn’t have some pulmonary risk stratification tool. And when you tie that together with the fact that COPD is a leading reason for admission in general, you can understand.
Counseling patients with diabetes on lifestyle change during primary care office visits is motivated by good intentions. We as primary care doctors are interested in prevention, lifestyle changes can positively affect many patients with diabetes, and patients do best when engaged in managing their disease1. But it’s difficult to show with data that brief physician encounters are effective at producing any of these outcomes.

Callus Debridement Can Be Diagnostic
Calluses form when shear forces and pressure induce the epidermis to reinforce itself. In patients with diminished pain sensation such as in diabetic neuropathy, continued friction from shear forces and pressure evolves the callus into a blister, then a blood blister (figure 1). When I see a bloody foot callus, I know that at some point, there was a break in the dermis. I don’t know if it has healed on its own or if it has expanded into a full blown ulcer because I can’t see past the callus. In fact, some calluses can be so thick I can’t even see the blood underneath! The only way to find out what’s hiding is to debride the callus.
Patrick S. Kamath, MD, is a professor of gastroenterology and hepatology at the Mayo Clinic in Rochester, Minnesota. His research interests include acute-on-chronic liver failure, nonalcoholic fatty liver disease, polycystic liver disease, Budd-Chiari syndrome and hereditary hemorrhagic telangiectasia. Dr. Kamath is internationally renowned as a leading researcher in hepatology and has also won numerous awards as an educator.
Why did you develop the MELD Score? Was there a particular clinical experience or patient encounter that inspired you to create this tool for clinicians?
Following a trans-jugular intrahepatic portosystemic shunt (TIPS) procedure for complications of portal hypertension, some patients do well and others fare poorly. My colleague in statistics, Mike Malinchoc, and I studied laboratory variables prior to the procedure and identified INR, serum creatinine, serum bilirubin and etiology of cirrhosis being predictive of survival. We developed a score based on these variables and demonstrated it predicted survival in a wide variety of patients with cirrhosis not undergoing TIPS. The score was originally called the Mayo End-Stage Liver Disease (MELD) model and was shown to be superior to the Child-Turcotte-Pugh score.

Dr. John Bedolla is the assistant director of research education and assistant professor of emergency medicine at the Dell Medical School at the University of Texas at Austin. He is also editor-in-chief of ED CLEAR, an evidence-based medical risk reduction program. Dr. Joe Habboushe is MDCalc’s co-founder and CEO. Earlier this year, the two sat down and talked about MDCalc’s content development process and future plans.
Kamal (Kim) Medlej, MD, is an attending physician in the department of emergency medicine at Massachusetts General Hospital and fellowship-trained in critical care, and a longtime contributor to MDCalc. Here’s Dr. Medlej’s take on applying evidence on managing pain, agitation, and delirium to his patients in the ICU.
Pain, agitation, and delirium (the ICU triad) are common in critically ill patients, and can be challenging for clinicians to manage, both in (1) ruling out and treating potential underlying causes, and (2) choosing appropriate sedatives and analgesics in those patients who need them.
This is a fascinating area of critical care medicine, although it can also be difficult and frustrating. While our insight and screening tools have improved, the management of patients with pain, agitation, and/or delirium remains difficult. This is a large topic with a significant amount of literature and opinions. This brief overview is in no way comprehensive, but more a personal view, approach and practice.
