Difficulty: MediumDisposition and Care Setting Transitions

An emergency department physician is evaluating a 48-year-old man with a 4-hour history of sudden-onset, right-sided pleuritic chest pain and mild dyspnea. He has a history of severe alcohol use disorder. The patient is currently unhoused and sleeps at a local nighttime-only community shelter. Vital signs show a temperature of 37.1°C (98.8°F), blood pressure of 128/82 mmHg, heart rate of 88/min, and respiratory rate of 16/min. Oxygen saturation is 97% on room air. Physical examination reveals clear lungs bilaterally and a regular heart rhythm. Laboratory studies demonstrate normal renal and hepatic function, and a high-sensitivity cardiac troponin I level within the normal reference range. Computed tomography pulmonary angiography reveals a small segmental pulmonary embolism in the right lower lobe. Echocardiography shows normal right ventricular size and function. The patient is alert, oriented, and demonstrates a clear understanding of his diagnosis. When discussing the treatment plan, he states, 'Just give me the pills so I can get back to the shelter before I lose my bed for the night.' Which of the following is the most appropriate next step in the disposition and management of this patient?

  1. Admit to a general medical floor to initiate anticoagulation and consult social services to arrange a safe care transitionAnswer
  2. B
    Discharge to the community shelter with a direct oral anticoagulant, as his low clinical severity score supports outpatient care
  3. C
    Admit to the medical intensive care unit for continuous hemodynamic monitoring and consideration of systemic thrombolytic therapy
  4. D
    Involuntarily hold the patient for treatment, as his substance use and housing status render him legally incompetent to refuse care
  5. E
    Admit to a psychiatric inpatient unit for management of his alcohol use disorder prior to initiating treatment for the pulmonary embolism

Answer

Admit to a general medical floor to initiate anticoagulation and consult social services to arrange a safe care transition.
This patient presents with a hemodynamically stable, low-risk pulmonary embolism. While patients with a simplified Pulmonary Embolism Severity Index (sPESI) of 0 are typically candidates for early discharge and outpatient management with direct oral anticoagulants, safe disposition also strictly requires a supportive home environment, reliable communication, and low risk of bleeding. This patient is unhoused, stays in a nighttime-only shelter, and has severe alcohol use disorder. These factors create an unacceptably high risk for medication nonadherence, loss to follow-up, and catastrophic bleeding. Therefore, the most appropriate disposition is admission to a general medical floor. This allows the care team to safely initiate anticoagulation while social services and case management coordinate a secure post-hospital transition, such as a medical respite program.

Step-by-Step Solution

1
Evaluate the patient's physiological risk profile using an objective severity score.
The simplified Pulmonary Embolism Severity Index (sPESI) is 0, indicating a low physiological mortality risk.
Risk stratification is the first step in determining whether a patient with a pulmonary embolism requires admission or can be managed as an outpatient.
2
Assess the patient's functional capacity and social determinants of health regarding treatment safety.
The patient is unhoused, uses a nighttime-only shelter, and has severe alcohol use disorder, representing severe psychosocial vulnerability.
Safe outpatient anticoagulation requires reliable medication adherence, ability to attend follow-up appointments, and a low risk of uncontrolled bleeding, none of which this patient has.
3
Synthesize objective scores with functional capacity to determine the final disposition.
Despite the low sPESI score, the high psychosocial risk mandates admission to a general medical floor to safely initiate treatment and involve case management.
Objective severity scores must always be contextualized with the patient's living situation and functional ability to ensure a safe care setting transition.

Key Concept

Safe care setting transitions require synthesizing objective clinical severity scores (e.g., sPESI) with a comprehensive assessment of the patient's functional capacity and social determinants of health.
