Abstract

Introduction: We examined the effect of the 2005 American Heart Association guidelines on survival in the Resuscitation Outcomes Consortium (ROC) Cardiac Arrest Epistry.

Methods: We surveyed 174 EMS agencies from 8 of 10 ROC sites to determine 2005 AHA guideline implementation, or crossover, date. Two sites with 2005 compatible treatment algorithms prior to guideline release, and agencies that did not adopt the new guidelines during the study period were excluded. Non-traumatic adult cardiac arrests that were not witnessed by EMS, and did not have do not resuscitate orders were included. A linear mixed effects model was applied for survival controlling for time and agency. The "crossover" date was added to the model to determine the effect of the 2005 guidelines.

Results: Of 174 agencies, 85 contributed cases to both cohorts during the 18 month period between 2005/12/01 and 2007/05/31. Of 7779 cases, 5054 occurred during the 13 month (median) interval before crossover and 2725 occurred in the five month (median) interval after crossover. The overall survival rate was 6.1%; 5.8% in the old cohort vs. 6.5%, p=0.23. For VF/VT patients, survival was 14.6% vs. 18.0%, p=0.063. Our model estimated no increase in survival over time (monthly OR 1.014, 95% CI 0.988, 1.041, p=0.28).

Conclusion: This study found no significant change in survival rate over time in the early months after implementation. Further longitudinal study is needed to determine the full impact of the guidelines on survival and methods to translate knowledge quickly and effectively in EMS.
