Match each patient's clinical presentation and associated risk stratification score with the most appropriate immediate disposition from the Emergency Department.
- Community-acquired pneumonia in a 68-year-old presenting with new-onset confusion, respiratory rate 34/min, blood pressure 85/55 mmHg, and BUN 24 mg/dL. (CURB-65 Score: 4)Admission to the Medical Intensive Care Unit (MICU)
- Moderately suspicious chest pain in a 55-year-old patient with hypertension and diabetes. Initial EKG shows non-specific changes; first troponin is normal. (HEART Score: 4)Admission to a Clinical Observation Unit
- Acute pulmonary embolism in a hemodynamically stable 42-year-old (HR 85/min, BP 120/80 mmHg, SpO2 98%) lacking significant medical comorbidities. (PESI Class I)Discharge home with a direct oral anticoagulant (DOAC)
- A single episode of melena in a 35-year-old who is hemodynamically stable with hemoglobin 14.5 g/dL, BUN 12 mg/dL, and no history of liver disease. (Glasgow-Blatchford Score: 0)Discharge home with prompt outpatient gastroenterology follow-up
Answer
The correct matches align each clinical risk score with its guideline-directed care setting: CURB-65 of 4 requires MICU admission; a HEART score of 4 requires an Observation Unit; PESI Class I allows home discharge with a DOAC; and a Glasgow-Blatchford Score of 0 allows home discharge with outpatient endoscopy.
Each risk stratification tool (CURB-65, HEART, PESI, GBS) has rigorously validated thresholds that dictate specific transitions of care. Recognizing these thresholds prevents both the under-triage of critically ill patients and the over-triage of low-risk patients.
