Alternatively, these data can be gathered by going to iPort Access (https://www.accesstocare.on.ca/cms/One.aspx?portalId=120513&pageId=128286) Calculated indicator value is based on ED visits submitted by 126 sites participating in the ER National Ambulatory Care Reporting System (NACRS) Initiative (ERNI) reporting to the NACRS database. Approximately 90% of ED Visits in Ontario are captured by hospital sites participating in ERNI (based on NACRS 13/14 data released July 2014). As of April 2009, patient’s stay in a designated Clinical Decision Unit (CDU) will be excluded in the total time spent in ED. This indicator was retired in the 2019/20 QIP.
