    As new advances are made in cardiac surgery, methods to collect accurate data in the long term on cardiac related events are essential so that a broader view of the clinical effectiveness of interventions can be obtained. Published studies involving long term follow up on patients with cardiac disease commonly rely on patient recall, obtaining data through self completion questionnaires or by interview. Evidence suggests that patients over-report, and general practitioners (GPs) under-report, clinical events.1–3 We investigated the sensitivity and specificity of reports from patients and their GPs for identifying admissions to hospital after discharge following their index admission for cardiac bypass surgery (CABG) and compared these with hospital information systems.
