Accuracy of the All Patient Refined Diagnosis Related Groups Classification System in Congenital Heart Surgery
Thursday, February 6, 2014
Source Name: Annals of Thoracic Surgery
The accuracy of the diagnosis in patients undergoing congenital heart surgery in a large administrative database was examined in over 14,000 patients aged 0 to 5. Patients admitted on day 1 of life and those undergoing ECMO had a much higher chance of being assigned non-cardiac diagnoses. Pts so misclassified had a substantially higher risk of mortality. This systematic misclassification may lead to inaccurate determination of case volumes and outcomes.
