Improving Risk Stratification of Emergency Department Patients With Acute Heart Failure

June 16, 2026 updated by: Kaiser Permanente

Improving Risk Stratification of Emergency Department Patients With Acute Heart Failure: Building and Testing a Machine-learning Platform for Personalized, Accurate, Real-time Risk Prediction

The primary goal is to build and test a previously developed and validated risk model and clinical decision support tool embedded within the electronic health record to improve risk stratification of emergency department (ED) patients with acute heart failure (AHF).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Enrolling by invitation

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study team will build an electronic health record-embedded clinical decision support tool using a recently developed risk prediction model that curates patient-specific data in real-time, accurately estimates short-term patient risk, and presents tailored clinical recommendations. This will be a regional implementation study in which the tool is turned on at 21 emergency departments (ED) across Kaiser Permanente Northern California (KPNC). The study team will validate risk predictions and study key clinical outcomes as part of this trial.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients presenting to KPNC emergency departments with eligibility criteria

Description

Inclusion Criteria:

  • Adult (≥18y) KPNC members treated in the ED for presumed acute heart failure

Exclusion Criteria:

  • Children (<18y).
  • Patients who left against medical advice or eloped prior to ED physician evaluation.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of patients with risk-stratified appropriate disposition
Time Frame: 24 hours
Risk-stratified appropriate disposition is defined as the proportion of ED encounters with concordant risk-based disposition (admission of high-risk patients and discharge of low-risk patients), assessed using STRATIFY risk calculator
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of patients with serious adverse events
Time Frame: 30 days from index ED visit
Serious adverse events include mortality, cardiopulmonary resuscitation (CPR), intubation/ventilation, new end-stage renal disease (ESRD), balloon pump placement, or percutaneous coronary intervention (PCI)/coronary artery bypass grafting (CABG)
30 days from index ED visit
Number of patients with all-cause mortality
Time Frame: 30 days from index ED visit
30 days from index ED visit
Number of patients with readmissions
Time Frame: 30 days from index ED visit
30 days from index ED visit
