The objectives of this study were (1) to determine if any patients did have orders in the Registry that were not released to them during a call; (2) explore the creation of an algorithmic model for matching patients; (3) to validate the current algorithm. Methods: Medical records for all patients believed to have a POLST (as determined by a call made to the POLST Registry) between 12/3/2009 and 7/31/2010 were compared to all POLST registrants who had an active form in the Registry through probabilistic linkage to determine if
