(a) Data is not shown, as the ICD-10-CA and CCI coding classification system had not yet been adopted by the province or territory. The exception is Quebec, which maintained the ICD-9 and CCP coding classification system up to 2005–2006. As of 2006–2007, Quebec began to submit in the ICD-10-CA and CCI coding classification system. As such, Quebec data prior to 2006–2007 may not be comparable with data from 2006–2007 onward. As of 2006–2007, all provinces and territories were submitting in the ICD-10-CA and CCI coding classification system; for this reason, Canadian rates are provided from 2006–2007 onward only.
(b) Data was suppressed due to rate instability or under-reporting. Details are provided in “About This Quick Stat.”
(c) Data is not available: Data is presented from regions with a population of at least 75,000 (from 2001–2002 to 2005–2006) or 50,000 (from 2006–2007 to 2014–2015). Nunavut did not submit data to CIHI in 2002–2003. Health regions in Nova Scotia, Manitoba and Alberta have changed over time. Data on the Total Caesarean Section Rate from 2006–2007 to 2012–2013 is available in the Health Indicators e-Publication; however, this indicator is included in this Quick Stats product as of 2013–2014. As of April 23, 2020, historical Total Caesarean Section Rate results have been aligned with the Health Indicators e-Publication. Data on the Preterm Birth Rate and Small-for-Gestational-Age Rate is available in Quick Stats as of 2007–2008. 2016–2017 data for Nunavut is incomplete and has therefore been suppressed.
(d) Changes in version 2009 of the ICD-10-CA and CCI coding classification system have resulted in changes to the methodology for deriving the Primary and Repeat Caesarean Section rates (see “About This Quick Stat” for more details). As such, data from prior fiscal years may not be comparable with data from 2009–2010 onward.
(e) Results are presented for a patient’s region of residence, rather than the location of the facility where hospitalization occurred. For P.E.I. and the territories, the entire province/territory is included as a region.
(f) Sources: Discharge Abstract Database (DAD) and Hospital Morbidity Database (HMDB), Canadian Institute for Health Information; Fichier des hospitalisations MED-ÉCHO, ministère de la Santé et des Services sociaux du Québec.
(g) Quebec data for 2006–2007 to 2009–2010 was sourced from MED-ÉCHO. As of 2010–2011, Quebec data was sourced from the HMDB.
(h) Results are shown as NA when there are no eligible records available for indicator calculation.
