Your Medical School Study Habits Become Your Doctor Work Habits

By Luke Murray

Your Medical School Study Habits Become Your Doctor Work HabitsIt was Friday afternoon and the morning lectures had just finished. I surveyed the challenge ahead of me: 20 lectures that I had only been through once, another 6 that I haven’t been through at all, and the test was Monday morning…

Time to do the obvious: panic.

In the words of every 13-year-old that’s ever sent a text message: “JK…kinda.”

While I did not physiologically manifest a full blown panic attack, the ‘plans’ I put together were almost totally void of the two things that would make them useful: (more…)

The “O”bnoxious Problem with the TORCHS Mnemonic

2

By Joe Savarese

The Obnoxious Problem with the TORCHS MnemonicPerhaps my clever title gave away the topic of this post, but my augmented interest in the TORCHS infections (since I started my OB/GYN rotation earlier this week) has encouraged me to create a better mnemonic. First, let me review the classic one. There are multiple versions, but here is one of the most common.

TToxoplasma gondii
OOthers
RRubella
CCMV
HHerpes simplex virus-2 and HIV
SSyphilis

If you are a second year student, I understand this mnemonic has been drilled into your head by now. Professors probably refer to it simply as the “TORCHS infections.” My intent is not to alter the traditional mnemonic but to improve the unhelpful “Other” stem part. (more…)

When Giving Your Presentation… “Just Talk”

0

By Luke Murray

When Giving Your Presentation Just TalkAs I wrote about in my earlier posts, ‘The Avoidable Cycle of Self-Doubt’ and ‘Give Your Presentation Backwards’, I used to be confused about what I ‘should’ be doing on wards… presentation-wise. Most of the time, I tried to do what I thought they wanted or leaned towards what the textbook said to do, or I hedged my bets by giving more information instead of less, because I was concerned I’d leave something out. I used to read every lab value and every section of the H&P out loud because…that’s what it says in Bates.

The problem was: my presentations were painfully boring because 90+% of what I was saying didn’t matter. And I was spending so much effort and brainpower collecting and reporting every last bit of information that I didn’t have the time (and my team didn’t have the patience to help me) intelligently organize and share the most important part of the H&P – the Assessment and Plan.

None of the residents presented in the classic med student way. They just talked about their patient in a generally organized way. That’s it.

Now in my second year of residency, I’m doing the same. And it’s making me a better doctor.

For example, I had a patient come into the ED last night, he was tachypnic, had increased work of breathing, and I was working him up appropriately but starting to feel in over my head and stuck in a few places, so I called my attending.

This was my ‘presentation’: (more…)

Mnemonic Monday: Fetal Heart Tracings

By Haley Masterson

Reading your first fetal heart tracing can be intimidating, but you will be a pro at interpreting accelerations, early decelerations, variable decelerations, and late decelerations once you read a few hundred of them. Until then, keep this mnemonic close at hand…
