Indicator Description and Calculation
 Description Number of emergency department (ED) visits and median length of stay (in minutes) for asthma Calculation: Description Length of stay = (Disposition Date/Time or Patient Left ED Date/Time) − (Registration Date/Time or Triage Date/Time) Asthma records are captured using the ICD-10-CA code J45. Unit of Analysis: ED visit Calculation: Geographic Assignment Place of service Calculation: Type of Measurement Number - Median length of stay (in minutes) Calculation: Adjustment Applied None Calculation: Method of Adjustment Not applicable Denominator Numerator Description: Number of ED visits and median length of stay for asthma Inclusions: 1. ED visit record with the following ICD-10-CA code documented as the Main Problem: Versions 2003, 2006, 2009, 2012 and 2015: J45 2. Visits from participating facilities in Prince Edward Island, Nova Scotia, Ontario, Manitoba, Saskatchewan, Alberta, British Columbia and Yukon 3.

Canadian and non-Canadian residents receiving care in participating Canadian EDs 5. Records with an invalid length of stay and an unknown triage level (applicable to number of ED visits only) 6. Records where sex is categorized as ''other'' are included in the ''all'' sex counts (applicable to number of ED visits only) 7. Records where birthdate is unknown are included in the ''total'' age counts (applicable to number of ED visits only) Exclusions: 1. Visits from non-participating ED facilities 2. Scheduled ED visits where Scheduled ED Visit Indicator = Y or ED Visit Indicator = 0 (as of 2011–2012) 3. Records with an invalid length of stay (applicable to median length of stay only) 4. Records where sex is categorized as undifferentiated (as of 2012-2013) 5. Records with invalid length of stay or patient registered but left without being seen or triaged (Visit Disposition = 02) (as of 2013–2014) (applicable to median length of stay calculation only)
Background, Interpretation and Benchmarks
 Rationale This indicator was developed to inform government planners, policy-makers, health system decision-makers, health care providers, patients and the general public. It can help raise awareness and allow ED planners to make more informed decisions.
