Children presenting with head injury are as unremitting in children’s hospitals as the “Frozen” soundtrack, and any physician in a pediatric ED inevitably manages their fair share. The ramifications of missing significant injury to a child’s delicate, developing brain are unnerving. A head CT is central to catching intracranial pathology, but widespread use is not benign, given the risk of malignancy from unnecessary radiation. However, criteria for judiciously navigating this tradeoff remain debated. When is CT appropriate for children with GCS scores of 13-15 and mild symptoms like transient loss of consciousness or vomiting?

When the MDCalc team isn’t scouring PubMed for studies to help our patients (and yours), we also like to read other stuff related to digital health, evidence, and the healthcare industry. It’s always hard to keep up with all the interesting articles on healthcare, and this year medicine has been a popular topic for journalists. So, we thought we’d share some of our favorite articles. Happy reading!

The CHA2DS2-Vasc Score is one of the most widely-used clinical risk scores for stroke. It’s arguably the best validated and is consistently in the top five most popular calcs on MDCalc. Professor Gregory Lip, the newest member of MDCalc’s Scientific Advisory Board, gave us an interview on developing and using the CHA₂DS₂-VASc Score.
Dr. Gregory Lip
Why did you develop the CHA₂DS₂-VASc Score? Was there a clinical experience that inspired you to create this tool for clinicians?
The availability of Non-Vitamin K Antagonist Oral Anticoagulants (NOACs), previously referred to as new or novel oral anticoagulants, has led to a major change in the landscape for stroke prevention in atrial fibrillation (AF). Clinicians are also getting better at understanding how to manage warfarin, recognizing the importance of the average time in therapeutic range (TTR). New data are also re-emerging on the poor evidence for the efficacy and safety of aspirin for stroke prevention in AF.

Ah, sepsis. You can’t solve a problem without defining it, and sepsis has been notoriously difficult to define, let alone treat. The body of data on sepsis is growing, as well as laypeople’s awareness of the disease. Yet it still manages to elude clinicians in many ways. We talked to Dr. Christopher Seymour, Sepsis-3 investigator and creator of the qSOFA Score, about using qSOFA to help in the management of sepsis.
Bonus: We also asked Dr. Seymour about his thoughts on vitamin C in sepsis. Come back to Paging MDCalc next week to see what he (and other critical care docs) had to say! Continue reading “Insights from Dr. Christopher Seymour, Creator of the qSOFA Score”
After a lot of hard work from MDCalc’s development team, we released Version 3.0 of MDCalc.com in January and just this past weekend we launched a few updates with Version 3.1. The new site offers a lot of great new features and customization that make using MDCalc even easier. Let’s jump into it! Continue reading “Tricks Up our New Website’s Sleeve: Version 3.1 is Here!”
The Padua Prediction Score is one of several validated venous thromboembolism (VTE)-related risk scores. It’s particularly useful in helping to determine whether hospitalized inpatients, who often have multiple comorbidities and thus multiple VTE risk factors, would benefit from pharmacologic prophylaxis over mechanical prophylaxis. We interviewed the first author on the derivation study, Dr. Sofia Barbar, for her insights on developing and using the Padua Prediction Score. Continue reading “Insights from Dr. Sofia Barbar – Creator of the Padua Prediction Score for Risk of VTE”
Imagine you went to buy an expensive piece of clothing. Rather than measuring your size, the store owner simply said “well, on average most folks require a medium, so let’s try that on, we can always re-size it later.” Continue reading “PulmCrit Wee: MDCalc for the perfect tape-measure intubation”

In medical school we spend little time learning about sore throats. After all, it’s just a sore throat.
Group A beta-hemolytic streptococcal (GAS) tonsillitis dominates our sore throat concern, because it can cause acute rheumatic fever and peritonsillar abscess. We have rapid antigen tests for GAS so that we can treat patients with that infection. Continue reading “Sometimes it’s NOT just a sore throat – adolescents and young adults are different”
Paradoxical embolism via patent foramen ovale (PFO) is a rare cause of stroke, but it’s not uncommon to find PFOs in patients without traditional stroke risk factors (about 1 in 4 people in the general population have a PFO). How should patients with no other convincing cause of stroke be counseled, especially if invasive PFO closure is being considered? We talked to Dr. David Thaler, creator of the Risk of Paradoxical Embolism (RoPE) Score, about his research and experience with taking care of patients with cryptogenic stroke.
Dr. David Thaler
Why did you develop the RoPE Score? Was there a clinical experience that inspired you to create this tool for clinicians?
PFOs have interested and frustrated me for years. They’re so common in the general population, and we find them all the time in stroke patients, old ones and young ones. And paradoxical embolism is definitely a thing—there’s no question that it happens—but because the prevalence is so high in the general population, there’s also no question that a lot of the PFOs that we find are incidental. That’s where this started from in my mind: Continue reading “Deciphering Cryptogenic Stroke with Dr. David Thaler, Creator of the RoPE Score”
With the launch of the ASCVD Calculator and the ASCVD algorithm we recently added to MDCalc (The difference? I’ll explain further down) we thought it might be nice to review the 2013 guideline. Let’s start at the beginning.
Before the ASCVD
A long time ago, in a galaxy far, far away, (2002) there were the ATP-III Guidelines — short for the “Adult Treatment Panel,” a group of cholesterol and lipid experts that attempted to figure out what the heck to do with patients with lipid issues. It really focused on LDL cholesterol and addressed trying to aggressively reduce it. Find high risk people with high LDL, and get that LDL down!
