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.

Indicator Description and Calculation
Description

The number of days a patient waited, between the date when the patient and the appropriate physician agreed to a cataract surgery and the patient was ready to receive it, and the date the patient received a planned cataract surgery

Calculation: Description

This indicator is calculated based on provincial and national wait time data for the first 2 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.

Exclusions:

  1. Emergency cases
  2. Days when patient was unavailable
  3. Abandoned procedures
Background, Interpretation and Benchmarks
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 understand access to care and to know how provinces are performing in terms of 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.

Targets/Benchmarks

Within 16 weeks (112 days)

The pan-Canadian benchmark specifies surgery within 16 weeks (112 days) for patients who are at high risk. There is not yet consensus on a definition of "high risk," so the benchmark is applied across all priority levels.

Updates

There may be some provincial exceptions to the standard methodology each year. For details, please see the Trend tab of CIHI’s wait time visualization.

Quality Statement
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 time visualization.

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. For details, please see the Trend tab of CIHI’s wait time visualization.
