PY - 2011 DA - 2011/12/14 TI - Evaluation of an automated safety surveillance system using risk adjusted sequential probability ratio testing JO - BMC Medical Informatics and Decision Making SP - 75 VL - 11 IS - 1 AB - Automated adverse outcome surveillance tools and methods have potential utility in quality improvement and medical product surveillance activities. Their use for assessing hospital performance on the basis of patient outcomes has received little attention. We compared risk-adjusted sequential probability ratio testing (RA-SPRT) implemented in an automated tool to Massachusetts public reports of 30-day mortality after isolated coronary artery bypass graft surgery.
