mr. pickens provide you with more details. >> thank you dr. colfax. i'm roland pickens, director of the san francisco health network in answer to your question in terms of medication management, there are medication rooms on each of the patient units at laguna. those rooms have computerized medication cabinets that hold the drugs. there are also or medication carts that are used to bring medications out of the room and onto the patient units. obviously the persons -- the systems in place at that time did not catch what happened in terms of some of the inappropriate medication use. as dr. colfax said, we have taken steps to remediate that right away and are continuing to analyse the process. there has been an increased monitoring and oversight by pharmacists at laguna honda. they have doubled their checks going from once a week to once a day, and they will continue as we bring in consultants to really help us analyse what has been the gaps that led to this behavior and what do we need to do to fill those gaps. [indiscernible] >> yes, thank you so much
