Diagnostic codes are widely used in research, yet their accuracy in reflecting true SCA events is uncertain. The objective of this study is to evaluate the relationship between administrative diagnostic code rank (listing order) and the likelihood of true SCA in patients presenting to the emergency department (ED).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>From a database of 22\u2009369 patients with VT\/VF\/SCA, we randomly selected 380 patients for detailed chart review. Diagnostic accuracy was confirmed when patients (1) had sustained a true VT\/VF\/SCA event during the index hospitalization and (2) when the event was not precipitated by non\u2010cardiac causes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Manual chart review for the 380 patients (age 71\u2009\u00b1\u200912 years, 53% women) confirmed that 65% experienced true VT\/VF\/SCA and 55% had an arrest unrelated to non\u2010cardiac causes. Diagnostic accuracy was 100% at priority rank #1 and declined significantly at lower ranks. In the overall larger cohort of 22\u2009369 patients, recurrence of VT\/VF\/SCA trended 3% lower (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.086) and all\u2010cause mortality was 5% higher (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) with each diagnostic priority rank decrease, over a mean follow\u2010up of 1.5 years.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Diagnostic codes show variable predictive accuracy for true VT\/VF\/SCA events, with the highest accuracy at priority rank #1. Higher\u2010priority codes identify patients most likely to have true SCA, while lower\u2010priority codes capture sick patients with other in\u2010hospital events.
