Prehospital Resuscitation On Helicopter Study (PROHS)

December 7, 2015 updated by: John Holcomb, The University of Texas Health Science Center, Houston
The Prehospital Resuscitation On Helicopter Study (PROHS) is a pragmatic, multicenter, prospective observational study of air ambulance-based prehospital resuscitation regimens currently utilized at the participating sites. Patients will be enrolled at participating sites that currently have blood products available on air ambulances and other sites that do not. This study will not change the current prehospital standard of care for resuscitation. The primary outcome will be in-hospital mortality and the primary unit of analysis will be the patient. Other outcomes of interest will include time to hemostasis, hospital length-of-stay, number of ventilator-free and ICU-free days, incidence of major surgical procedures, complications (transfusion-related acute lung injury [TRALI], acute kidney injury [AKI], multiple organ failure [MOF], acute respiratory distress syndrome [ARDS], sepsis, intra-abdominal complications, thromboembolic complications, compartment syndromes), lifesaving interventions, the amount and type of blood products and concentrates transfused (including prehospital), wastage of prehospital blood products and concentrates, use of external and internal hemostatic devices, and functional status at discharge/discharge destination.

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.

Detailed Description

All patients arriving to the participating center's trauma emergency department via helicopter directly from the scene will be screened and initial data collected. Of that group, all patients who meet the "highest risk" category (based on vital signs, type of injury, use of tourniquet, and/or intubation) or received blood during transport will be followed through "direct observation" through the initial resuscitation period and then indirectly through medical chart review until hospital discharge or 30 days after admission (whichever occurs first).

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

15 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The target population for this study is trauma patients who are transported to one of the participating Level I trauma centers via air ambulance, directly from the scene, and meet the eligibility criteria.

Description

Inclusion Criteria:

Criteria for "at risk" population

  • Patients with traumatic injuries received directly from the scene via air ambulance service (did not receive a lifesaving intervention at an outside hospital or healthcare facility)
  • Estimated age of 15 or older or greater than/equal to a weight of 50 kg, if age unknown Criteria for "highest risk" population
  • Meet at least one of the following during prehospital care: HR >120 bpm, SBP ≤90 mmHg, penetrating truncal injury, tourniquet application, pelvic binder application or intubation.
  • Received blood products during transport (for those facilities with blood product availability)

Exclusion Criteria:

  • Prisoners (defined as those received directly from a correctional facility.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Received blood products during transport
There is no intervention as this is an observational study. The first group will be the patients that received blood products during the helicopter transport from the scene of the injury per standard of care guidelines at the participating institutions.
Other: No intervention
Observational study
Received crystalloid during transport
There is no study intervention. The second group will be the patients that did not receive blood products during the helicopter transport because blood products are not available or part of the standard of care during flight.
Other: No intervention
Observational study

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.

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.
