Early termination of resuscitation in in-hospital cardiac arrest and impact to the outcome calculations

Abstract

Background: Some in-hospital resuscitation attempts are assessed futile and terminated early on. We hypothesized that if these cases are reported separately, the true outcome of in-hospital cardiac arrest is better reflected. Methods: We conducted a 3-year prospective observational Utstein-style study in Tampere, Finland. All adult in-hospital cardiac arrests outside critical care areas attended by hospital's rapid response team were included. Resuscitation attempts that were terminated within 10 minutes were considered early terminations. Results: The cohort consisted of 199 in-hospital cardiac arrest patients. Twenty-seven (14%) resuscitation attempts were terminated early due to the presumed futility of the attempt with median resuscitation duration of 5 (4, 7) minutes. These cases and the 172 patients with full resuscitation attempt were of comparable age, sex and comorbidity. Early terminated resuscitation attempts were more often unwitnessed (63% vs. 10%, P
