In most emergency departments, beds are a hot commodity. But some patients don’t actually need a bed for their treatment – and accurately identifying those people is a low-lift but effective way to increase efficiency without sacrificing care quality, finds a study recently published in the journal Management Science.
The researchers developed a simple decision tree, informed by mathematical and machine learning models, to help staff decide whether a patient truly needs a bed or can be routed to a “vertical processing pathway” – that is, an area where they can be treated sitting up. Many hospitals already have such an area but don’t necessarily have a systematic way to decide which patients are treated there.
American teenagers start their school day too early.
Medical experts have been clear for years: sleep cycle changes during puberty make it hard for teenagers to learn in the early morning. Later school start times have been linked to better sleep, improved mental health, stronger academic performance and even safer driving.
Most school district leaders know about this problem and care about fixing it. But changing the schedule can feel operationally impossible.
An audio journey of how data and analytics save lives, save money and solve problems.

While the 100-day review is designed to better understand several aspects of U.S. supply chains, it will hopefully force companies to reassess how they move products through the chain.
Today, an estimated 90% of the world’s goods are transported by sea, with 60% of that – including virtually all your imported fruits, gadgets and appliances – packed in large steel containers. The rest is mainly commodities like oil or grains that are poured directly into the hull. In total, about US$14 trillion of the world’s goods spend some time inside a big metal box.
Defying the pessimists who doubted the ability of Yale students to follow COVID-19 safety protocols, the Yale student body conducted itself in a safer manner than expected last semester. To put a number on it, the R0 value, or the number of secondary cases generated by an initial case, of the student body last semester was 1.85—compared to the 2.3 that experts set as the maximum value that could still keep student infections under control. Yale researchers Joseph Chang, Forrest Crawford, and Edward Kaplan calculated this number and devised the twice-weekly testing plan implemented among Yale College’s on-campus student body last semester.
Big-power muscle flexing helps explain much of the world’s vaccine inequities, but there's another reason behind insufficient doses: The challenge of making them is unprecedented.
So much has changed since COVID-19 pressured the medical industry to innovate in the Pharma supply chain, making a lasting impression.
