Pharmacotherapy Review and Recertification Course:
Complex Pneumonia Case
Marc H. Scheetz, Pharm.D., BCPS (AQ-ID), FCCP, M.Sc.
Professor of Pharmacy Practice and Pharmacology
Director of Pharmacometrics Center for Excellence
Midwestern University, Downers Grove, Illinois
Chicago College of Pharmacy and Graduate Studies

Chicago, Illinois
Learning Objectives:
At the conclusion of this session, given a patient case, the participant should be able to
• Select the appropriate treatment and monitoring for a complex patient-case with multiple
conditions, including pneumonia, acute renal insufficiency, sepsis, chronic obstructive
pulmonary disease (COPD) and dehydration.
• Interpret clinical data, including lab, physical examination and vital signs.
• Determine and prioritize pneumonia-related treatment goals.
• Determine approaches to manage drug allergies and select next best drug therapy when
primary drugs are precluded
• Discuss approaches to limiting antimicrobial over use by stewarding antibiotic usage
appropriately
• Discuss safety issues in patients receiving treatment for pneumonia.
Format: Today’s session will be a highly interactive discussion of the attached case studies.
Premise: Participants in this course are pharmacists who practice in clinical acute care settings. You are
responsible for evaluating and monitoring the patient’s therapy. You are responsible for providing
comprehensive patient management and education.

“I can’t breathe!”
AB with a PMH of COPD presented worsening shortness of breath and has been on your general medicine
floor for 2.5 days. Two weeks prior to today’s admission, she presented to your emergency department (ED)
with hypoxia and dehydration. She was initially started on intravenous levofloxacin, although she was later
found to have H3N2 influenza A and treated with oseltamivir 75 mg orally every 12 hours. She returned to
her baseline state of health and was discharged home 3 days ago with a prescription for an additional 3 days
of oseltamivir. On the day of discharge the patient displayed the following vital signs.
BP= 137/97 mm Hg Pulse= 64 bpm, regular R=16/min T=98.2°F (oral)
Because she noticed increased production of thick, yellow sputum and used her albuterol inhaler five times in
rapid succession, she presented to the ED again. Vitals signs on presentation were: BP= 135/85 mm Hg, T=
99.9°F. Her O saturation was 88% on room air, so she was placed on 4 L/min of O via nasal cannula Her O
2 2 . 2
saturation improved to 92% with this intervention. The ED physician admitted her to the general medicine
floor for a COPD exacerbation. AB’s breathing gets progressively worse 2.5 days after admission.
