Objective: We sought to identify changes in neurological outcome over time following initial training and subsequent implementation of team-focused CPR in an inpatient setting where responders practice specific roles with emphasis on minimally interrupted chest compressions and early defibrillation.
Methods: This retrospective pre- vs post-intervention study was conducted at an urban 900-bed teaching hospital and Level I Cardiac Resuscitation Center. We included adult patients suffering in-hospital cardiac arrest occurring in non-emergency department and non-intensive care unit areas who received CPR and/or defibrillation. We compared survival with good neurological outcome at time of hospital discharge in the one-year periods before and after implementation of team-focused CPR. To investigate skill degradation, we compared cumulative survival with good neurological outcome in 3-month intervals against the before team-focused CPR baseline. Trained research associates abstracted explicitly defined variables from electronic health records using a standardized form and data dictionary to achieve consistency between collaborators.
Results: Of 296 IHCAs, 207 patients met inclusion criteria and were analyzed. In 104 patients before team-focused CPR initiation, survival with good neurological outcome was 21%. In the 12-month period following team-focused CPR initiation, survival with good neurological outcome was 31% in 101 patients, risk difference 9.9% (95% CI -2 to 22%; p = 0.14). By quarterly time intervals, following team-focused CPR implementation, the cumulative survival with good neurological outcome at 3 months was 42%; at 6 months 37%; at 9 months 31%; and at 12 months 31%.
Conclusion: In our single-institution implementation of team-focused CPR for in-hospital cardiac arrest, outcomes significantly improved at 6 months before declining towards baseline.
