Difficulty: HardDisposition and Care Setting Transitions

Review the clinical scenarios of the following four patients presenting to the emergency department. Match each patient with their most appropriate initial disposition and care setting based on validated clinical risk stratification tools.

  • A 72-year-old with community-acquired pneumonia presenting with new-onset disorientation, respiratory rate of 34/min, blood pressure of 85/55 mmHg, and blood urea nitrogen of 24 mg/dL.Intensive care unit (ICU) admission
  • A 58-year-old with atypical chest discomfort, non-specific T-wave inversions on ECG, normal initial high-sensitivity troponin, and a history of hypertension and diabetes mellitus.Observation unit admission for serial monitoring and provocative testing
  • A 32-year-old with one episode of coffee-ground emesis, pulse 82/min, blood pressure 118/75 mmHg, hemoglobin 14.8 g/dL, blood urea nitrogen 12 mg/dL, and no melena or comorbidities.Discharge home with outpatient gastroenterology follow-up
  • A 64-year-old with a CT-confirmed pulmonary embolism, normal mental status, pulse 88/min, blood pressure 125/80 mmHg, oxygen saturation 97% on room air, and no cardiopulmonary history.Discharge home with immediate initiation of direct oral anticoagulation

Answer

The correct pairings match each patient to their disposition based on their respective calculated risk scores: the pneumonia patient requires ICU admission (CURB-65 of 5), the chest pain patient requires observation (HEART score of 4), the gastrointestinal bleed patient can be discharged for outpatient endoscopy (Glasgow-Blatchford score of 0), and the pulmonary embolism patient can be discharged home on anticoagulation (sPESI of 0).
Each patient's clinical presentation was evaluated using a disease-specific risk stratification tool. The pneumonia patient's CURB-65 score of 5 mandates ICU care. The chest pain patient's HEART score of 4 requires observation. The gastrointestinal bleed patient's Glasgow-Blatchford score of 0 allows safe discharge for outpatient follow-up. The pulmonary embolism patient's sPESI of 0 qualifies them for immediate outpatient anticoagulation.

Step-by-Step Solution

1
Calculate the CURB-65 score for the patient with pneumonia.
The patient has 5 points (Confusion, BUN >19 mg/dL, RR >=30/min, BP <90/60 mmHg, Age >=65).
A CURB-65 score of 4 or 5 indicates severe pneumonia with high mortality, requiring intensive care unit admission.
2
Calculate the HEART score for the patient with chest pain.
The patient has 4 points (History: 1, ECG: 1, Age: 1, Risk factors: 1, Troponin: 0).
A HEART score of 4 to 6 indicates moderate risk for major adverse cardiac events, necessitating observation unit admission for serial troponins and stress testing.
3
Calculate the Glasgow-Blatchford Score (GBS) for the patient with the upper gastrointestinal bleed.
The patient has a GBS of 0 (normal BUN, normal hemoglobin, normal vitals, no melena/syncope, no hepatic/cardiac comorbidities).
A GBS of 0 indicates a very low risk of requiring intervention, allowing for safe discharge and outpatient management.
4
Calculate the simplified Pulmonary Embolism Severity Index (sPESI) for the patient with the pulmonary embolism.
The patient has an sPESI of 0 (Age <80, no cancer, no chronic cardiopulmonary disease, normal vitals, normal oxygenation).
An sPESI of 0 indicates a low risk of 30-day mortality, making the patient a candidate for early discharge and outpatient management with a direct oral anticoagulant.

Key Concept

Clinical decision rules (such as CURB-65, HEART, Glasgow-Blatchford, and sPESI) are essential for determining the appropriate triage, disposition, and care setting transitions for patients presenting to the emergency department.
