Furthermore the relative importance of bystander-initiated cardiopulmonary resuscitation BCPR and ACLS and the effectiveness of their combination have not been clearly demonstrated. Methods Using a prospective nationwide population-based registry of all OHCA patients in Japan we enrolled 95 072 patients whose arrests were witnessed by bystanders and 23 127 patients witnessed by emergency medical service providers between 2005 and 2007. We divided the bystander-witnessed arrest patients into Group A ACLS by emergency life-saving technicians without BCPR Group B ACLS by emergency life-saving technicians with BCPR Group C ACLS by physicians without BCPR and Group D ACLS by physicians with BCPR . The outcome data included 1-month survival and neurological outcomes determined by the cerebral performance category. Results Among the 95 072 bystander-witnessed arrest patients 7 722 were alive at 1 month including 2 754 with good performance and 3 171 with vegetative status or worse. BCPR occurred in 42 of bystander-witnessed arrests. In comparison with Group A the rates of good-performance survival were significantly higher in Group B odds ratio OR 95 confidence interval
