Description
Percentage of patients within a province who received planned total knee replacements within 26 weeks (182 days) from the date they were ready to be treated
Calculation: Description

This indicator is calculated based on provincial and national wait time data for the first two quarters of the fiscal year (April–September).

The percentage within benchmark is calculated by dividing the number of cases who received care within the benchmark by all cases, multiplied by 100.

Unit of Analysis: Client or patient

Calculation of all-Canada estimates:

All-Canada Percentage Meeting Benchmark

The national percentage meeting benchmark estimate was calculated as follows:

National percentage meeting benchmark = Total patients meeting benchmark for each province ÷ Total procedures performed × 100

Calculation: Geographic Assignment

<div role="button" class="expandableTitle" aria-controls="backgroundRegion">Background, Interpretation and Benchmarks</div>
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

The greater the percentage meeting the benchmark, the greater the proportion of patients in that province who received treatment within the benchmark (182 days).

There may be some provincial exceptions to the standard methodology each year. For more information, visit the Wait Times website and view provincial exceptions (http://waittimes.cihi.ca/All/knee).

Caveats and Limitations

Some provinces may have some exceptions and their methodology may be slightly different than the standard methodology. For more information, visit the Wait Times website and view provincial exceptions (http://waittimes.cihi.ca/All/knee).

Trending Issues

Since 2008, an increasing number of provinces have adapted to the standard methodology in order to increase the comparability of results. When comparing data for a particular province over time, attention should be given to the exceptions.
