Start with delirium in a quiet older patient, then tighten antibiotic choice by matching cell wall agents to organism, resistance and site.
Quiet older patients need delirium screening, not just observation.
Today’s briefing is split between older adult delirium in the emergency department and the practical use of cell wall antibiotics. Start with the SGEM delirium episode. It is the best first listen because it tackles a common miss: the older patient with acute confusion, reduced alertness or agitation whose delirium is not recognised early. It gives a workable route through bedside screening with 4AT or DTS plus bCAM, reminds you that hypoactive delirium is easy to miss, and keeps head CT selective rather than routine.
Open the antibiotics episode next when infection treatment is the live issue. It tightens prescribing by separating penicillins, cephalosporins, carbapenems, vancomycin and fosfomycin by mechanism, resistance and route. Take one behaviour into practice: use a consistent delirium screen when an older patient is not acting as usual, and choose the narrowest cell wall inhibitor that fits the likel
A quiet older patient with acute confusion, drowsiness or agitation is easy to miss when gestalt is doing the work. Open this first for bedside delirium screening with 4AT or DTS plus bCAM, selective head CT, and the reminder to look for the precipitant rather than stop at the syndrome.
Useful when antibiotic choice starts to drift wider than the case supports. It separates penicillins, cephalosporins, carbapenems, vancomycin and fosfomycin by mechanism, resistance and route, including why oral vancomycin suits Clostridium difficile while systemic infection needs intravenous treatment.
When an older patient arrives drowsy, agitated or simply not usual for them, stop relying on gestalt alone. Use one delirium screen consistently, get collateral history early, and record why head CT is or is not justified. If infection is also in play, choose the narrowest cell wall inhibitor that matches site and likely organism.
What should I not miss in the quiet older patient with reduced alertness?
Hypoactive delirium. Acute confusion or drowsiness can still represent delirium, and gestalt alone misses too many cases.
When is head CT justified in suspected delirium?
Use it selectively when there is trauma, a fall with unclear history, or new focal neurological findings. Routine head CT is not the take-home for every delirious older adult.
When is oral vancomycin the right route?
For Clostridium difficile infection, because poor absorption leaves high drug levels in the gut. Systemic infection needs intravenous dosing.
