IE cases not captured by coding were ascertained by reviewing clinical data sources (echocardiogram reports, cardiothoracic surgical and device implantation registries and an IE biobank). We used a definite, possible or pathological diagnosis of IE as per the European Society of Cardiology (ESC)\u00a0Modified criteria for IE\u00a0as the reference standard for diagnosing IE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We identified 353 hospitalisations with principal or secondary ICD10\u2010AM diagnosis codes at discharge. Of these, 313 patients had IE as per the ESC Modified criteria. A further 51 patients (14%) with IE meeting the ESC modified criteria\u00a0= were found not captured by coding during the same period. ICD10\u2010AM codes for IE had an overall sensitivity of 0.86 (95% confidence interval (CI) 0.82\u20130.90), specificity of 1.00 (95% CI 1.00\u20131.00), a positive predictive value of 0.89 (95% CI 0.85\u20130.92) and a negative predictive value of 1.00 (95% CI 0.99\u20131.00). Coding identified the causative organism with an overall sensitivity of 0.77 (95% CI 0.72\u20130.81) and specificity of 1.00 (95% CI 1.00\u20131.00), with high accuracy for the most common organism,\n                      <jats:italic>Staphylococcus aureus<\/jats:italic>\n                      (sensitivity 0.88, 95% CI 0.80\u20130.93; specificity 0.95, 95% CI 0.89\u20130.98). Coding demonstrated high accuracy for detection of in\u2010hospital deaths (sensitivity 0.91, 95% CI 0.75\u20130.98; specificity 1.00, 95% CI 1.00\u20131.00) and surgical management (sensitivity 0.91,
