AMoX5ORNOT: a new scoring system for antibiotic-prescribing



One thing that strikes me as we wade through the treacle of increasingly perplexing abbreviated patient scoring systems (CHA2DS2-VASc, HAS-BLED et al) is that the bread and butter areas of medicine are being left out.

Where, for example, are the helpful scoring systems to help us decide whether a sniffly punter needs antibiotics? Here, that’s where. Because, as a service to grassroots medicine, I have devised AMoX5ORNOT, a scoring system devised to work out the risk to the patient of not having an antibiotic, to be used in conjunction with F3-U DOCT2AH2, which works out the risk to the GP of not prescribing an antibiotic.

This is how it works: the patient presents with cough and requests antibiotics – should I prescribe?

First, work out the AMoX5ORNOT score:

Already running half an hour or more late +1

More than two visits still to do +1

Expectorated phlegm colour – sliding scale of greenness thus:

Pistachio +1

Shamrock +2

Olive +3

Teal  +4

Glow in the dark +5

Waiting room packed +1

Friday evening +1

Not given many antibiotics so far today, so feeling pretty smug +1

Possible total AMoX1-5ORNOT score 10

Next, work out the F3-U DOCT2AH2 score, as follows:

Football shirted (+2 if no shirt at all, +3 if no shirt in winter) +1 to +3

Patient Unlikely to be impressed by your talk about the self-limiting nature of viral illness +1

Double negatives used by patient (eg ‘The other doctor didn’t give me nuffink’) +1

Neck size >18” +1

Tattoos visible without undressing patient (+2 if ‘Cut here’ tattoo on neck) +1 to +2

Always’ used in presentation (‘Always goes to my lungs’ or ‘Always need antibiotics’) +1

Head shaved (+2 if woman) +1 to +2

Possible total F3-U DOCT2AH2 score 11

Finally: look at the two scores. The higher the AMoX5ORNOT, the greater the likelihood you’re going to need to prescribe antibiotics. And the higher the F3-U DOCT2AH2, the greater the likelihood that your face will be rearranged if you don’t.

Alternatively, you could go with your gut GP instinct. It’ll amount to the same thing.
