Internal Medicine Knowledge Library

Presentation-by-presentation guides written to be said out loud — the investigations, the decisions and the guideline behind each one, mapped to the IMT clinical station.

Acute Medicine

Sepsis and NEWS2: Recognition, the First Hour and Escalation

NEWS2 is a track-and-trigger tool, not a diagnosis; suspect sepsis in any patient with likely infection and a NEWS2 of 5 or more, and deliver the first-hour bundle while escalating.

Gastroenterology

Acute Upper GI Bleeding: Risk Scores, Resuscitation and Endoscopy Timing

Score every upper GI bleed with the Glasgow-Blatchford score at first assessment; a score of 0 can be considered for early discharge without inpatient endoscopy, and unstable patients go to endoscopy immediately after resuscitation.

Endocrine

Diabetic Ketoacidosis: Diagnosis, Fixed-Rate Insulin and the Traps

DKA needs all three of ketonaemia, acidosis and hyperglycaemia (or known diabetes); treat with fluid first, then fixed-rate insulin at 0.1 units/kg/hr, and continue long-acting insulin throughout.

Renal

Acute Kidney Injury: Staging, the Reversible Causes and When to Call Renal

Stage AKI on creatinine rise or urine output, work through pre-renal, renal and post-renal causes, and know the four indications for urgent dialysis by heart.

Frequently asked questions

What is the Knowledge library?

A free, evidence-based reference covering the orthopaedic conditions that matter for the ST3 interview and day-to-day practice — management-focused, anchored to the current BOAST and NICE standards, and reviewed against the live guideline text.

How is each article kept accurate?

Every guideline claim is checked against the current published standard (BOAST, NICE, GIRFT) and each article lists its key evidence. The last-reviewed date is shown on every article.

How does this help with the ST3 interview?

Each condition links to how it comes up at interview — the station vignette and opening questions — and the question bank turns the same topics into full station practice with model answers.
