Difficulty: MediumDisposition and Care Setting Transitions

A 68-year-old man presents to the emergency department with a 3-day history of productive cough, fever, and shortness of breath. Over the past 24 hours, he has also developed severe nausea and has vomited 6 times. He has not been able to keep any food or liquids down, including his daily medications. Medical history includes hypertension and type 2 diabetes mellitus.

On physical examination, he appears fatigued. Temperature is 38.4°C (101.1°F), blood pressure is 118/76 mm Hg, pulse is 98/min, and respiratory rate is 22/min. Pulse oximetry shows 94% on ambient air. He is alert and fully oriented. Mucous membranes are dry. Lung auscultation reveals crackles in the right lower lobe. There is no accessory muscle use.

Laboratory results:

Creatinine1.1 mg/dL0.7–1.3 mg/dL
Glucose155 mg/dL70–110 mg/dL

Chest radiograph demonstrates a right lower lobe infiltrate without a pleural effusion. The patient is given an initial dose of intravenous ceftriaxone and azithromycin, as well as 1 L of normal saline. He continues to have severe nausea and dry heaves despite receiving intravenous ondansetron.

Which of the following is the most appropriate disposition for this patient?

  1. A
    Discharge home with oral amoxicillin and azithromycin
  2. B
    Discharge home with daily home health visits for intravenous antibiotics
  3. C
    Admit to a skilled nursing facility
  4. Admit to a general medical floorAnswer
  5. E
    Admit to the intensive care unit

Answer

Admit to a general medical floor
The patient presents with community-acquired pneumonia (CAP). While risk stratification tools such as the CURB-65 score or the Pneumonia Severity Index (PSI) are critical for guiding disposition, they must be combined with a comprehensive clinical assessment. This patient's CURB-65 score is 1 (due solely to age over 65), which typically suggests that outpatient management is safe. However, he has severe, intractable nausea and vomiting, signs of dehydration (dry mucous membranes), and an inability to tolerate oral intake despite intravenous antiemetics in the emergency department. The inability to take oral fluids and oral antibiotics is a major secondary criterion that necessitates inpatient admission. Therefore, the most appropriate disposition is admission to a general medical floor for intravenous hydration, intravenous antibiotics, and close monitoring until he demonstrates clinical stability and can safely transition to oral medications.

Step-by-Step Solution

1
Calculate the patient's objective risk stratification score for community-acquired pneumonia (e.g., CURB-65).
The patient has a CURB-65 score of 1 (due to age over 65), with normal mentation, normal blood pressure, respiratory rate < 30, and BUN < 19 mg/dL.
Objective scoring systems provide a baseline mortality risk and initial guidance for disposition settings.
2
Evaluate the patient's functional status, symptom severity, and ability to adhere to an outpatient treatment plan.
The patient has intractable vomiting, dry mucous membranes, and fails to tolerate oral fluids or medications despite receiving intravenous antiemetics.
Clinical guidelines mandate that patients must be able to maintain adequate oral hydration and absorb oral medications to be safely managed in an outpatient setting.
3
Synthesize the objective score with the functional assessment to determine the appropriate care setting.
Despite a low objective risk score indicating low baseline mortality, the functional inability to take oral medications necessitates acute inpatient care on a general medical floor.
Failure to tolerate oral intake is a major secondary criterion that overrides a low CURB-65 score, mandating inpatient admission for intravenous antibiotics, fluid resuscitation, and monitoring.

Key Concept

While risk stratification scores (such as CURB-65 or the Pneumonia Severity Index) guide disposition in community-acquired pneumonia, patients with low scores must still be admitted to an acute inpatient setting if they exhibit a functional inability to maintain oral intake or absorb oral medications.
