Gerald Park — Urosepsis, CrCl 28, Pip-Tazo Day 3, De-escalating to Ceftriaxone

About This Case

This clinical reasoning case presents a patient with gerald park / urosepsis / crcl 28 / pip-tazo day 3 / de-escalating to ceftriaxone in a infectious disease context. Learners work through a structured 10-phase simulation covering initial differential, history-taking, physical examination, labs and imaging, and management planning.

"The team wants to de-escalate to ceftriaxone 1g IV q24h for pan-sensitive E. coli UTI/bacteremia. CrCl is 28. Gerald is also on vancomycin empirically (levels: AUC 380). He has been afebrile for 36 hours. Review the de-escalation plan: ceftriaxone dose in CKD, vancomycin discontinuation criteria, total antibiotic duration for bacteremic UTI, and what monitoring continues after de-escalation."

How the Simulation Works

1. Read the patient presentation and form your initial differential diagnosis
2. Interview the AI patient to gather history and explore your hypotheses
3. Perform a focused physical examination based on your differential
4. Order appropriate labs and imaging, then interpret the results
5. Revise your diagnosis and develop a management plan
6. Receive personalized teaching feedback from your AI attending, Dr. Patel

What You'll Learn

This case builds skills in systematic clinical reasoning, hypothesis-driven history-taking, appropriate test ordering, and evidence-based management. It is designed for Pharmacy students and practicing clinicians seeking to sharpen diagnostic thinking in infectious disease.
