At a Glance

Who is it for?

iatroX:UK clinicians who want guideline-grounded interpretation and next-step management (not just the numeric score), plus Q&A and scenario exploration.

MDCalc:Clinicians who want quick, trustworthy access to calculators, risk scores, and clinical tools at the bedside.

Why choose iatroX?

  • **Guideline context & management**: helps translate a score into “what to do next” using UK sources (NICE/CKS/BNF).
  • **Natural-language questions**: you can ask about thresholds, caveats, and what changes in specific patient contexts.
  • **Free for individuals** and designed around UK clinical workflows.
  • **Beyond calculators**: Ask + Brainstorm + Quiz (reasoning + learning continuum).

Why choose MDCalc?

  • **Gold standard for calculators**: fast, familiar, and deeply embedded in day-to-day clinical work.
  • **Breadth**: hundreds of tools across specialties with a consistent, calculator-first experience.
  • **Efficient output**: perfect when you already know the tool you need and want a reliable number quickly.
  • **App-first convenience**: quick access on mobile for bedside use.

In-Depth Analysis

Overview

MDCalc and iatroX solve adjacent problems:

  • MDCalc helps you compute a score (fast, reliable, widely adopted).
  • iatroX helps you apply that score in UK-guideline context and turn it into a practical plan.

Quick take

  • Choose MDCalc if you need the number now.
  • Choose iatroX if you need what the number means for UK management and next steps.

Why “score vs context” matters

In real clinical work, the hard part often isn’t the arithmetic — it’s interpretation:

  • Does the score change management today?
  • What thresholds matter in UK practice?
  • What safety-netting or escalation is recommended?

iatroX is designed for that “translation layer”.

When to use each

  • Use MDCalc when:

    • you know the exact tool you need
    • you want a quick, standardised calculation

  • Use iatroX when:

    • you want UK-guideline-grounded interpretation and management
    • you need caveats, edge cases, and “what if…” exploration
    • you’re moving from calculation → decision → action

Use-Cases

CHA2DS2-VASc, Wells, CURB-65, etc.

When to choose iatroX

  • Use iatroX to ask: “Given this score, what does UK guidance suggest next?”
  • Helpful for caveats, red flags, and how comorbidities affect the plan.

When to choose MDCalc

  • Use MDCalc to calculate the score quickly and consistently.

Explaining a score to a trainee

When to choose iatroX

  • Ask follow-up questions (“why this threshold?”, “what changes if…”), grounded in UK guidance.

When to choose MDCalc

  • Show the tool and its references; strong for teaching the calculation and validation context.

Building a practical management plan

When to choose iatroX

  • Use Ask/Brainstorm to map score → diagnosis → management steps and safety-netting in UK practice.

When to choose MDCalc

  • Use the calculator as the numeric input, then move to another resource for guideline pathways.

FAQs

Does iatroX replace calculators like MDCalc?
Not necessarily. Many clinicians use calculators to compute the score and then need a guideline-grounded pathway for what to do next. iatroX is designed to support that interpretation and decision layer.
Is MDCalc only for US clinicians?
No — it’s used globally. However, management pathways and thresholds can differ by country and guideline source, which is where a UK-focused assistant like iatroX can add value.
What’s the simplest workflow?
Calculate the score (MDCalc) → ask iatroX what UK guidance suggests for management given that score and patient context.
