Early Warning System

April 11, 2022 updated by: Washington University School of Medicine

Comparing an Early Warning Alert With a Standardized Triage Intervention to Standard Care for the Management of Hospitalized Patients on General Hospital Wards.

The study will begin in 2013 whereby patients having an early warning system (EWS) alert will be randomized to be seen by the rapid response team (RRT) for triage versus usual care. A RRT is usually made up of a nurse and/or a physician who respond to a requested activation of the RRT (called an "ACT"). The intervention will occur as follows:

Detailed Description

The study will begin in 2013 whereby patients having an early warning system (EWS) alert will be randomized to be seen by the rapid response team (RRT) for triage versus usual care. A RRT is usually made up of a nurse and/or a physician who respond to a requested activation of the RRT (called an "ACT"). The intervention will occur as follows:

  1. Real-time monitoring of the eight general hospital wards (GHWs)((10100, 10200, 11100,11200, 12100, 12200, 14400, 14500)will occur 24 hours daily. Through multiple past collaborative efforts and studies involving interventions at BJH, informatics personnel have already demonstrated that they can accomplish this task using their computing and algorithmic resources. The prediction tool (PT) employed is a validated PT aimed at identifying any form of clinical deterioration occurring on a GHW requiring ICU transfer or leading to patient death.
  2. Patients meeting the prediction criteria for an increased risk of clinical deterioration will be identified on the GHWs. An automated text message will be generated that provides the patient's name, their room number, the date and time of the message, and text indicating that they meet the criteria for risk of deterioration. Messages will only be generated for patients assigned to the intervention group.
  3. The EWS text message will be sent to the on-call RRT nurse's phone. These are phones that are transferred from one RRT nurse to the other as changes of shift occur. It is their primary means of communicating with the hospital.
  4. The RRT nurse for the intervention patients will go into the flagged patient's room within 10 to 15 minutes of receiving the message and perform a clinical assessment. Based on the RRT nurse's assessment either no additional action need occur or he/she will call either the physician on duty or activate an ACT as well as apply the "four D's", which was internally established at Barnes-Jewish Hospital (BJH) for treatment of patients on GHWs identified to have impending clinical deterioration. The four "D's" refer to the following: Discuss level of care, Drugs for treatment (e.g., antibiotics), Diagnostics (lab tests, cultures), and Damage control (e.g., use of intravenous fluids, oxygen).

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

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
571

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

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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.
Placebo Comparator: Routine care
General hospital ward patients will receive routine care.
Other: routine care
Experimental: Intervention arm
The intervention with early warning system monitoring is to have the rapid response team assess the patients real-time.
Other: Early warning system monitoring.
General hospital ward patients will be monitored 24/7 for clinical deterioration using the early warning system monitoring developed at Washington University.

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
ICU Transfer
Time Frame: Patients will be assessed for the primary outcome measure during their hospital with an average of 14 days.
Patients transferred to the ICU from a general hospital ward will be assessed as having met the outcome.
Patients will be assessed for the primary outcome measure during their hospital with an average of 14 days.

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.

Time Frame
Mortality
Time Frame: Patients will be asessed for the secondary outcome measure during an average of 28 days..
