Report ID: HP17
© 2017 Canadian Institute for Health Information (CIHI)
(a) Due to privacy and confidentiality concerns, and to minimize the risk of residual disclosure, volumes of fewer than 5 visits have been suppressed in the cells and removed from total visit counts.
(b) Emergency department (ED) visits for 2003–2004 to 2016–2017 are included, based on the data element Registration Date. These statistics reflect the number of visits, which does not necessarily equal the number of individuals.
(c) The number of facilities submitting ED visit data to NACRS varied between 2003–2004 and 2016–2017. Due to this variation, trending across fiscal years is not recommended. Please refer to “About this Quick Stat” for more details.
(d) Historical comparability of median length of stay might be affected by a number of issues associated with the NACRS time elements; please refer to “About this Quick Stat” for more details.
(e) The Visit Disposition “Discharged home” also includes those discharged to a place of residence, such as a nursing or retirement home.
(f) The Visit Disposition “Not seen or left” includes those who left without being seen or left against medical advice.
(g) The “all” sex category includes those categorized as male, female and other. Detailed counts for the “other” category are not shown for privacy reasons, as the figures are lower than 5.
(h) The “total” age category includes those with an unknown age. Detailed counts for the “unknown” category are not shown for privacy reasons, as the figures are lower than 5.
