Application of Mechanical Cardiopulmonary Resuscitation Devices and Their Value in Out-of-hospital Cardiac Arrest: A Retrospective Analysis of the German Resuscitation Registry

October 11, 2016 updated by: Jan-Thorsten Graesner, MD, German Resuscitation Registry
The aim of this study was to analyse a large CPR database, the German Resuscitation Registry, to evaluate potential benefits of mechanical CPR devices over manual CPR in adult cardiac arrest victims. The primary endpoint considered is ROSC.

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

In a retrospective analysis of the German Resuscitation Registry between 2007-2014, investigators examined the outcome after using mechanical CPR on return of spontaneous circulation (ROSC) in adults with out-of-hospital cardiac arrest (OHCA). Investigators compared mechanical CPR (Intervention group) to manual CPR (control group). According to preclinical risk factors, investigators calculated the predicted ROSC-after-cardiac-arrest (RACA) score for each group, and compared it to the rate of ROSC observed. Using multivariate analysis, investigators adjusted the influence of the devices' application on ROSC for epidemiological factors and therapeutic measures.

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.
Observational

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.
19609

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patient suffering OHCA and be resuscitated by EMS where the data were delivered to the German Resuscitation Registry

Description

Inclusion Criteria:

  • out of hospital cardiac arrest
  • during time prod from January 2007 until December 2014
  • CPR attempted

Exclusion Criteria:

  • Investigators excluded cases in which CPR was continued for less than five minutes, or duration of CPR was missing, as the outcome in this early period is not affected by the CPR mode.
  • Children aged less than 18 years and patients of unknown age were also excluded as the devices are not approved for resuscitation on children.
  • An active compression-decompression (ACD) is a hand-held suction device, to compress and actively decompress the chest after each compression.
  • Investigators also excluded cases where ACD CPR was used, because it constitutes a different technology.
  • Cases due to trauma were excluded as application of mechanical CPR devices may be limited due in traumatic events.
  • Cases where data on ROSC and/or CPR mode was missing were also excluded.

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
return of spontaneous circulation
Time Frame: sustained ROSC at any time latest after 24 hours
sustained return of spontaneous circulation at any time during CPR
sustained ROSC at any time latest after 24 hours

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 1, 2014

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
