Learn to think like an experienced clinician by turning messy patient stories into structured medical problems. Master the use of pre-test probability, avoid cognitive biases, and balance the risks of testing and treatment.
Like Duolingo, but for Clinical Reasoning: Making Medical Decisions. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Framing the Case and Calculating Odds and Selecting Diagnoses and Managing Uncertainty. It assumes you already know the basics.

Key ideas in Clinical Reasoning: Making Medical Decisions
- Semantic qualifiers convert informal patient phrasing into paired opposing clinical axes.
- Qualifiers like acute vs chronic or mono vs poly immediately shrink differential diagnostic categories.
- Abstracting clinical features allows fast retrieval of matched textbook disease profiles.
- Illness scripts organize diagnostic recall around predisposing factors, insult, and clinical features.
- Clinicians match patient presentations against idealized disease scripts rather than exhaustive feature lists.
- Distinctive triggers like stasis combined with risk factors activate specific scripts like deep vein thrombosis.
- Vascular events like emboli strike over seconds to minutes with maximal intensity at onset.
- Infections and inflammatory processes typically declare themselves over hours to several days.
- Neoplastic and degenerative conditions develop insidiously over months to years.
- A diagnostic pivot point is an unexpected, highly specific acute finding that anchors the case.
- Long-standing stable chronic conditions are background context that should not distract from acute pivots.
- Pairing high fever with a new murmur establishes a high-yield pivot directly suggesting infective endocarditis.
- A problem representation is an iterative working draft that must update when contradictory data emerges.
- Failing to update a problem representation in the face of refuting data leads to premature diagnostic closure.
- New objective findings often change the core semantic qualifiers from acute to subacute or focal to diffuse.
- In very low-prevalence groups, most positive results are actually false positives.
