Description

Crude assisted delivery rate (overall) among vaginal deliveries

Rationale

Assisted delivery rates among vaginal deliveries continue to vary among provinces and territories. Given this variability, this indicator can be used 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 Canada to compare its rates with the rates of other countries.

Interpretation

This indicator provides contextual information on obstetrical services across Canada.

Caveats and Limitations

In order to provide a more stable rate estimate, only data 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) was reported. Additional indications for suppression were rate instability and under-reporting. As of 2015–2016, regions are not suppressed based on population; instead, the following suppression methodology is used:

  • Suppression due to privacy: To ensure privacy, a suppression rule is applied to all clinical indicator results. Numerators and/or denominators between 1 and 4 are suppressed.
  • Suppression due to unstable results: Unstable indicator results are suppressed. In general, these are indicator results with a denominator between 1 and 49.
