Right-Siting PE Care: Implementation of a Hestia-Based Outpatient Discharge Pathway in a High-Volume Urban Emergency Department

André Freire, MD · Babak Toosi, MD | Department of Emergency Medicine, Montefiore Einstein | Pre-launch · No outcome claims made
Background

Outpatient treatment is guideline-supported for carefully selected, low-risk PE. The operational problem is not just risk prediction. Patients need medication in hand, clear discharge instructions, and reliable early follow-up.

38.4% Treated at home in Hestia arm Roy et al., 2021
1.33% 30-day composite outcome (VTE, bleed, death) HOME-PE
0 Recurrent or fatal PE HOME-PE
Local Problem

Low-risk PE patients may still be admitted for logistics: medication cost, uncertain access, incomplete documentation, or lack of fast follow-up.

Each avoidable admission adds boarding time, inpatient cost, and patient disruption without changing the anticoagulation plan.

Measures
Process
Pathway use · DOAC load · Voucher use · Aftercare message sent
Outcome
PE admission rate · 72-hour follow-up completion
Balancing
ED return visits · Bleeding events · Recurrent VTE · First-fill failure
Aim & ED Workflow

Design a standardized Hestia-based ED discharge pathway for hemodynamically stable patients with confirmed acute PE who meet safety, medication access, and follow-up criteria.

Intervention Bundle
Implementation Status
Anticipated Impact

A low-risk PE discharge pathway can convert evidence into an operational bundle: risk stratification, medication access, and reliable follow-up.

This poster reports design and implementation readiness. Outcome analysis will follow after launch.
Clinical Safety Filters
❤️Hemodynamics
SBP ≥100 and HR <110 without PE-related instability
🩸Bleeding Risk
No active bleeding or high-risk bleeding condition
💨Oxygen Need
No oxygen requirement expected beyond 24 hours
⚕️Treatment Complexity
No thrombolysis, embolectomy, HIT, pregnancy, severe renal/liver impairment
🏠Social Stability
Housing, phone, pharmacy access, and ability to return
👤Clinician Judgment
Physician-in-charge may overrule discharge when the story does not fit
Hestia No-Go Domains

Instability  ·  Thrombolysis/embolectomy need  ·  Bleeding risk  ·  Oxygen need  ·  PE on anticoagulation  ·  IV analgesia need  ·  Medical or social admission need  ·  CrCl <30  ·  Severe liver disease  ·  Pregnancy  ·  HIT history

Hestia-negative status is necessary, not sufficient. Medication access, follow-up, and clinician judgment still decide discharge.

Equity Logic
Medication access is treated as a safety criterion, not an afterthought.
Next Steps
  1. Complete Epic SmartSet build.
  2. Confirm Aftercare scheduling pathway and callback loop.
  3. Launch pilot with weekly review of process, outcome, and balancing measures.
  4. Report first post-launch run chart once sufficient cases accrue.
Project Summary

We designed a Hestia-based outpatient PE pathway for a high-volume Bronx safety-net ED. The pathway embeds low-risk PE screening into Epic through .HESTIAPE, a PE Discharge SmartSet, 72-hour Aftercare referral, and a voucher workflow for first-fill DOAC access. Planned measures include pathway use, follow-up completion, ED returns, and admission rates among Hestia-negative patients. Target after launch: 20% reduction in logistically driven PE admissions.
