Know your Wells! Clinical Prediction Rules in PT

Well, well, well…they prepare us for a lot in DPT school, I think we all have had nightmares of those “RED FLAGS.” Often it feels like a terrific overload and that even though they are preparing us for the ‘worst’ … likely it won’t be something we actually see in clinic.

However, last Friday I went in to get one of my patients out of bed and he started to complain of some leg pain. So…here I am all alone, looking at an edematous (*swollen), red, painful leg and thinking to myself –> No. Flipping. Way. Then out of no where my mind clicks on and I was actually able to run through the Well’s Clinical Prediction Rule for DVTs (Deep Vein Thromboses) right there in my little ‘ol brain.

So quick, do you remember?

Alright, how did you do? Check yourself at the bottom.

For those non-PT students out there, a DVT is a medical emergency !! So when my patient scored 4 points on this screen, I let my CI and the nurse know and a doppler was ordered that ultimately  confirmed my suspicions. Luckily, once medicated my patient was just fine and we even got up and did some walking today. Emergencies can be nerve wracking but it is good to know that we are really quite prepared for all those scary red flags.
