Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Conventional EMS CPR | Conventional EMS CPR group will include patients from January, 2013 through December, 2014, as to refer to the historic control population who did not receive any of study interventions. | 334 | 6,201 | OG000 | ClinicalTrials.gov |
| Group 2 | Bundled EMS CPR | The main study phase will begin in January, 2016 through December, 2017, for a total of two years. Patients during the main study phase will have received one or more study interventions as applicable.~Bundled EMS CPR approach including dispatcher-assisted CPR, 3-person team CPR, and feedback CPR monitoring device: Gold standard EMS CPR refers to our bundled approach to providing high quality EMS CPR through one or more intervention(s) as applicable including 1) dispatcher-assisted CPR, 2) multi-tiered team CPR, and 3) feedback CPR. | 441 | 6,469 | OG001 | ClinicalTrials.gov |
