ABIM Exam Review Practice Question of the Week: Community-Acquired Pneumonia
Here’s a practice question directly from Knowmedge’s Internal Medicine Board (ABIM) Exam QVault.
In which of the following scenarios is it appropriate to allow outpatient treatment of community-acquired pneumonia (CAP)?
A. 67-year-old male with CAP, blood pressure of 120/85mmHg, and confusion B. 68-year old male with CAP, blood pressure of 130/80mmHg, and respiratory rate of 18/min C. 69-year old female with CAP, blood pressure of 125/82mmHg, and creatinine of 2.1mg/dL (Baseline is 0.8mg/dL) D. 58-year old female with CAP, blood pressure of 100/50mmHg, and confusion E. 32-year-old female with CAP, blood pressure of 90/50mmHg, altered mental status, and respiratory rate 34/min
Explanation
After diagnosing a patient with community-acquired pneumonia, we must determine whether the patient needs to be hospitalized or not. In order to facilitate this decision, the CURB-65 guidelines can be used. CURB stands for:
● C – Confusion (altered mental status)
● U – Uremia
● R – Respiratory rate greater than 30/minute
● B – Blood pressure that is low (Systolic <90mmHg or Diastolic <60mmHg)
● 65 – Age 65 years or greater
Each category is assigned 1 point
● 0-1 points total means the patient can be treated as an outpatient
● 2 points total requirements treatment in the medical ward
● 3 or more points requires ICU admission
Let’s go over the answer choices:
● Choice A (67-year-old male with CAP, blood pressure of 120/85mmHg, and confusion) has 2 points (age greater than 65 and confusion) and should require admission to the medical ward.
● Choice B (68-year-old male with CAP, blood pressure of 130/80mmHg, and respiratory rate of 18/min) will be the scenario that will require outpatient therapy. This patient only has one point (age greater than 65) so he can be treated for CAP as an outpatient.
● Choice C (69-year old female with CAP, blood pressure of 125/82mmHg, and creatinine of 2.1mg/dL) has 2 points (age greater than 65 and compromised renal function) which means admission to medical ward is most appropriate.
● Choice D (58-year old female with CAP, blood pressure of 100/50mmHg and some confusion) has 2 points (low blood pressure and confusion). Even though this patient has 2 points, this patient may require ICU admission because the patient may be septic. For such scenarios, the CURB score simply serves a guideline but the clinical picture plays a bigger role in deciding where the patient will receive the most appropriate care.
● Choice E (32-year-old female with CAP, blood pressure of 90/50mmHg, altered mental status, and respiratory rate 34/min) has 3 points (altered mental status, respiratory rate greater than 30/min and low blood pressure) that will require the patient to go to the ICU.
