Pneumonia is a classic UKMLA topic, and mastering the CURB-65 score is essentially your bread and butter for the AKT. It’s the primary tool we use in the UK to decide who can safely go home with a script and who needs a hospital bed.

Let's start by breaking down the score itself and what those numbers actually mean for your patient. I'll pull up a clear visual for the CURB-65 criteria to help it stick.

I've found a great summary table for the CURB-65 criteria. It's a simple 0-5 point scale that directly correlates with mortality risk.

In the UK, we follow the NICE guidelines for managing Community-Acquired Pneumonia (CAP). The CURB-65 score doesn't just predict mortality; it dictates our entire management plan, from where the patient is treated to which antibiotics we prescribe.

Management & Admission Criteria

• Score 0-1 (Low Severity): These patients can usually be managed safely at home.
• Score 2 (Moderate Severity): You should strongly consider hospital admission or, at the very least, a "hospital-supervised" outpatient approach.
• Score 3 or more (High Severity): This is an urgent hospital admission. If they hit 4 or 5, you need to involve the ICU/Critical Care team early.

Antibiotic Choices (NICE Guidelines)

For the AKT, remember that we typically treat for 5 days now, rather than the old 7-10 day courses, unless the patient isn't improving.

• Low Severity (Home): First-line is Amoxicillin (500mg TDS). If they have a penicillin allergy, go for Doxycycline or Clarithromycin.
• Moderate Severity (Hospital): We usually go for dual therapy to cover atypical pathogens. First-line is Amoxicillin + Clarithromycin.
• High Severity (Hospital): We step up the heavy hitters. First-line is Co-amoxiclav + Clarithromycin.

I'll pull up some detailed lessons on CAP management so you can dive deeper into the specific dosages and special cases (like Legionella or Staph. aureus).

Those lessons will give you the full breakdown of the microbiology and the finer points of management.

One last high-yield tip for the AKT: if you're in a GP setting, we use the CRB-65 score (no Urea measurement needed). The scoring and management thresholds remain the same, but it's designed for when you don't have immediate access to blood results.

Since CURB-65 is so critical for your exams, why don't we try a quick game to make sure you've got those criteria and management steps locked in?
