Nudging High Emergency Department Utilizers to Consider Non-emergent Healthcare Resources

March 11, 2026 updated by: Amir Goren, Geisinger Clinic

Point of ED Discharge Interactive Outreach: High ED Utilizers

The goal of this campaign is to reduce unnecessary ED visits by providing patients who are high ED utilizers (with a visit of any acuity) with alternative resources to manage their health outside of the ED. In this campaign, patients will be randomized to receive one of two types of outreach following discharge aligned with the goal. Outreach may occur via (1) a phone call from a Geisinger Community Health Worker (CHW) or Community Medical Assistant (CMA); current standard practice or (2) an interactive chatbot message providing similar information and questions to those provided by the CHW/CMA. The study team will measure whether ED use differs across patients in different outreach conditions. The study team will also examine whether patients followed through on the message-specific calls to action in the messages differently across conditions.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

1126

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Description

Inclusion Criteria:

  • Geisinger Health Plan insurance or KACO membership
  • Any PCP or no PCP
  • Visit of any acuity
  • 4 or more ED visits in the past 6 months

Exclusion Criteria:

  • Institutionalized
  • Cannot be contacted via the communication modality being used in the study (i.e., SMS), due to insufficient/missing contact information in the electronic health record or because the patient opted out
  • Admitted to hospital

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Community Health Worker/Community Medical Assistant Outreach
Patients will receive outreach from a community health worker or a community medical assistant, as is current standard practice, including guidance about ED-alternative resources to encourage care outside of the ED when appropriate.
Behavioral: Live outreach
High ED utilizers will be called (and possibly visited) by a CHW/CMA guiding them through ED-alternative resources.
Other Names:
  • Call
Experimental: SMS Chatbot Messages
Patients will be sent interactive SMS chatbot messages, including guidance about ED-alternative resources to encourage care outside of the ED when appropriate; patients will not receive outreach from a community health worker or community medical assistant.
Behavioral: Automated interactive messages
High ED utilizers will be sent SMS text messages guiding them through ED-alternative resources, with different guidance (including a follow-up phone call from a healthcare worker) depending on patient responses.

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.

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
