Implementation of a Multidimensional Bundle for
Dispatcher-assisted CPR in a Horizontal Dispatch System
is Associated with Increased Bystander CPR and
Good Neurological Survival from OHCA
Background
Bystander CPR(BCPR): increase OHCA survival
The guidelines indicate pre-arrival DATCPR instructions/measurement to increase the % of BCPR
However the impact of those guidelines on survival is not well known.
• Understanding and improving low bystander CPR rates: a systematic review of the literature. CJEM 2008;10:51–65.• CPR with chest compression alone or with rescue breathing. N Engl J Med 2010;363:423–33.5.• Emergency medical service dispatch cardiopulmonary resuscitation pre-arrival instructions to improve survival from OHCA: A Scientific statement from the American
Heart Association. Circulation. 2012;125:648-655.• International consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations. Circulation. 2010;122:S250-
275.
Objective To describe the impact of a comprehensive bundle of
DATCPR on BCPR and survival from OHCA in a horizontal computerized-aided dispatch (CAD) system.
Methods – the setting
Taipei, capital of Taiwan 2.68 million population 272 square kilometres EMS – fired based
computerized assisted dispatch (CAD)
1 centralized dispatch center
40 dispatchers + 5 nurses/4 teams
a horizontal dispatch
< 60 seconds, call to dispatch

Results After adjusting for witnessed arrest, shockable
rhythms, age, sex, and pre-hospital time intervals, TH, good neurological outcome after the bundle intervention was still significantly higher in our study. (adjusted odds ratios: 2.1 [95% 1.1-4.4])
Conclusion We developed and demonstrated successful
implementation of a multidimensional bundle for dispatcher-assisted CPR in our horizontal dispatch system.
There are significant improvements in the rates of BCPR and good neurologic outcome of OHCA in our study.
