Clinical Tools
Teaching and decision-support tools by Anthony Rosania, MD.
Clinical Tools
Chest Pain Workup
HEART score with the ESC 0/1-hour high-sensitivity troponin algorithm, combined into a disposition with each pathway's miss rate.
PE Workup
Wells score, PERC rule, and D-dimer interval likelihood ratios (Kohn 2017) for a Bayesian post-test probability.
GOLD COPD
Exacerbation severity (Rome) with ED treatment, NIV and disposition; GOLD grade and A/B/E group; initial and follow-up inhaler therapy.
Educational & Informatics
How FHIR Apps Work
How a tool opens from inside the chart and fills itself in, with live launches against a public test EHR.
Usability Lab
Six hands-on lessons: a hall of broken interfaces, spot-the-flaws, a usability M&M, a timed EHR shift, fix-it-yourself design, and the laws behind it.
Barriers to Ordering
Twelve possible-PE cases with order-entry barriers switched on at random: see whether friction cuts CT angiograms in the right patients.
Barrier Dynamics
System dynamics of ordering barriers: causal loops and a two-year simulation of why friction on CT ordering drifts, rebounds and backfires.
Herd Immunity Simulator
Agent-based SIR outbreak model: adjust R₀, vaccination coverage, and pathogen (measles, COVID-19, flu, Ebola, smallpox).
ED Boarding Simulator
Monte Carlo of a 50-bed ED coupled to a 120-bed inpatient unit: watch boarders accumulate as noon-clustered IP discharges clear beds; tune admit rate, LOS, and transfer delay.
GPT-2 Logit Lens
What a language model "believes" at each of its 12 layers as it generates text.
