However little is known about the inter- and intra-reviewer reliability of the CPC. Methods We undertook an investigation to assess the inter-reviewer and source document reliability of the CPC among a cohort of survivors from out-of-hospital ventricular fibrillation cardiac arrest n 131 in a large metropolitan area between November 1 2003 and December 31 2005. Subjects with a CPC of 1 or 2 were classified as favorable outcome and those with CPC 3 or greater were classified as unfavorable outcome. One abstractor first used the discharge summary alone to determine the CPC. All 3 abstractors independently reviewed the entire hospital record. Reliability was assessed by determining the proportion of determinations that agreed between abstractors and the respective kappa statistics. We also evaluated the implications for determining survival with favorable neurological outcome when survival to hospital discharge was 20 and 30 . Results When the entire hospital record was used to determine CPC favorable neurologic outcome CPC 1 or 2 was recorded in 92 by abstractor 1 89 by abstractor 2 and 74 by abstractor 3. Agreement was 96 kappa between abstractors 1 and 2 84 kappa between abstractors 2 and 3 82 kappa between abstractors 1 and 3. The 3-way kappa was . Agreement was 90 kappa between the discharge summary alone and the entire hospital record. If .
