Wait Times for Hip Replacement (Percentiles)
50th percentile: Half of all patients waited this many days before receiving care.
90th percentile: 1 out of 10 patients waited this many days or more before receiving care.
This indicator is calculated based on provincial and national wait time data for the first two quarters of the fiscal year (April–September), and includes all procedures that are publicly funded under the provincial health plan.
Measures:
50th percentile: Half of all patients waited this many days before receiving care.
90th percentile: 1 out of 10 patients waited this many days or more before receiving care.
Unit of Analysis: Episode of care
Calculation of all-Canada estimates:
All-Canada Median and 90th Percentile Waits
The national estimate for the 50th and 90th percentiles was calculated using a weighted average of provincial submissions. Weights were calculated using provincially submitted surgical volumes.

Wait Times for Hip Replacement (Percentiles)
Short/Other Names

Description
The number of days a patient waited, between the date when the patient and the appropriate physician agreed to a total hip replacement and the patient was ready to receive it, and the date the patient received a planned total hip replacement surgery.
Rationale
In 2004, Canada's first ministers agreed to work toward reducing wait times for five priority areas: cancer treatment, cardiac care, diagnostic imaging, joint replacement and sight restoration. CIHI was mandated to collect wait time information and monitor provincial progress in meeting benchmarks.
Many factors affect wait times, for example, availability of resources, efficiency of a particular facility, seasonal effects, volumes, patient choice, patient condition, follow-up care and/or treatment complexity.
This indicator can be used to help understand access to care and to know how provinces are performing in providing access to services.
Interpretation
50th percentile: Half of all patients waited this many days before receiving care.
90th percentile: 1 out of 10 patients waited this many days or more before receiving care.

Caveats and Limitations
Some provinces may have some exceptions and their methodology may be slightly different than the standard methodology. For details, please see the Trend tab of CIHI’s wait times visualization.
Trending Issues
Since 2008, an increasing number of provinces have adapted to the standard methodology to improve the comparability of results. When comparing data for a particular province over time, attention should be given to the exceptions. For details, please see the Trend tab of CIHI’s wait times visualization.

Comments
In 2023, Saskatchewan began reporting wait times based on a new set of health regions. Data for previous years (from the old health regions) has been mapped to the new health regions.
