Study summary

The survival after intrahospital cardiac arrest has been reported to 15%. In Norway this varies between 16 and 23%.). Many factors are associated with survival after cardiac arrest, both intra- and prehospital. Recent studies have not included information about individual patient factors and the outcome after cardiopulmonary resuscitation (CPR). In the current hospital, we are able to record patient specific information related to a cardiac arrest/CPR situation, and thereby be able to assess patient-related factors associated with both detection, treatment and outcome of CPR.

Read the detailed description

Several factors have been associated with survival, e.g. to monitor hands-off time(Odds ratio, OR, for 2.48, 95% KI 1.11-5.56, p=.03), monthly assessment of all cardiac arrest cases (OR 6.9, 95% KI 1.41-33.92), and includin av local coordinator for CPR (OR 2.93, 95% KI 1.08-7.94, p=.03), as well as depth of compressions. Nevertheless, information about cardiac arrests and CPR have not been assessed in relation to patient specific information. In the current hospital, we are able to record the CPR sequence, and see this in relation to other patient- and case- specific information such as initial cardiac rythm, time to first compression, hands-off time, quality of CPR, and factors affecting the treatment and outcome.

The hospital has 71 registered defibrillators used in CPR. The current study will both gather retrospective data- not seen in relation to patient specific information, and prospective data related to specific patients.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jan 2026; primary completion for Dec 2027, 23 months later.

Of 84 non-industry observational studies under Death, half reached primary completion within 60 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 245. This study's planned 23 months is below that.

Counting every sponsor, half of 87 studies reached it within 60 months; a quarter within 23 and three quarters within 245.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 5, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
