Antimicrobial Fantasy Draft

Antimicrobial stewardship, as a team sport. A live, phone-based game where resident teams treat real cases on the projector — and the scoring rewards exactly the reasoning we're trying to build.

~30–45 min · any group size · phones + a projector · one facilitator · nothing to install
Why it matters
Residents learn antibiotics as a list. We want them to think in systems.

Naming drugs is easy; using them well is the hard part — and it's exactly where habits form early and stick. Formulary makes the good habits the way to win.

Empiric overkill

Reaching for the broadest agent "to be safe" — the reflex that drives resistance, cost, and C. diff.

Slow to de-escalate

Cultures come back and the regimen doesn't change. Narrowing on data is a learned discipline.

Cost & harm blind spots

Price, duration, and C. diff risk rarely enter the bedside calculus — until they're made visible.

What residents practice
Three learning objectives — each built into the scoring

The game isn't a quiz bolted onto trivia. Its mechanics are the objectives: to win, a team has to reason the way we teach.

1
Antibiotics have roles, not just names

Teams draft a bench of agents grouped by role — antipseudomonal β-lactam, atypical coverage, MRSA, anaerobes, urinary. A live "cover the field" checklist forces the question every good empiric plan answers: what am I actually covering? They read a real local antibiogram to draft, not a memorized list.

The board — your local antibiogram

Start broad, then narrow as data comes in

Day 0 is an empiric bet under uncertainty. When cultures return, the board reveals the susceptibility and teams must de-escalate to the narrowest agent that still covers. The single biggest reward in the game is landing on "narrowest effective" — de-escalation is the winning move, not an afterthought.

Cost-conscious, stewardship-minded care

Every regimen accrues cost per day, and broad or prolonged therapy quietly raises a C. diff roll at the end of each case. Overkill wins the moment and loses the game. Residents feel the downstream cost of "just in case" — the harm that's usually invisible at the bedside.

The shared story: the patient, the cultures, the reveal, the live standings.

Phones

Each team's console. A rotating captain submits the team's call — everyone debates it.

🎛️

Facilitator

You. Open a case, advance the days, hit "Score & reveal." That's the whole job.

Teams draft a bench of antibiotics, then treat a case that unfolds over several days. Each day they choose a disposition (discharge / admit / ICU) and a regimen (which drugs, IV or oral). Picks auto-save on the phone; the facilitator advances and the board scores every team at once. Then the next case. Highest total after the last case wins.

8 cases span the bread-and-butter of inpatient ID — cystitis, pyelonephritis, pneumonia, cellulitis, S. aureus bacteremia, febrile neutropenia, meningitis — each grounded in IDSA / WRNMMC guidelines and a local antibiogram.

How it's scored
The leaderboard rewards stewardship, not carpet-bombing

Scoring is transparent and guideline-anchored. Teams see exactly why each day earned or lost points — the feedback that makes the reasoning stick.

Points for

Narrowest effective therapy+15
Correct de-escalation once cultures return+15
Appropriate empiric coverage+10
Right level of care (disposition)+10
Matches your local antibiogram, not just the guideline+5

Points off

Guideline-concordant, but your antibiogram doesn't back it0
Overbroad — it worked, but it was overkill−10
Inadequate — missed the bug−15 to −20
Can't complete outpatient (e.g. IV on discharge)−15
Cost, and a C. diff hit at case close− / roll

Final score = clinical points − cost − C. diff. A team can cover every bug and still lose to one that treated narrow, cheap, and clean.

Why it works
Engaging on the surface, rigorous underneath
🗣️
Active & social. Teams argue the plan out loud — the discussion is where the learning happens, not a lecture.
Immediate, specific feedback. Every choice is scored with a clinical reason on the spot — the fastest way to correct a habit.
📚
Guideline-grounded. Cases and answers are built on IDSA & WRNMMC CPGs and a real local antibiogram.
🛡️
Red-teamed for concordance. The scoring engine was exhaustively audited so guideline-correct care never gets penalized by chance.
What you'd need
Drop it into a noon conference. Zero setup.

30–45 min

Fits a noon conference or an academic half-day slot.

📱
Phones + a screen

Web-based. Residents scan a QR code — nothing to install.

👥
Any group size

Split the room into teams of 2–5. Scales from 6 to 60.

🆓
One facilitator

You run it from one screen. Free to use.

Let's run one at conference.

Try a case yourself in two minutes, then I'd love to pilot it with a resident session.

No account, no install — it runs in any browser.
Make it your program's.

Your antibiogram, your formulary, your prices — and your own cases. The ten that ship are a starting point, not the curriculum. Five steps in a browser; no spreadsheets emailed around, nothing to install, and a checker that tells you in plain English whether the right answer still wins.

Needs the facilitator key — ask me and I'll set you up.
