Wait Times for Bypass Surgery

Description
The number of days a patient waited, between the date when the patient and the appropriate physician agreed to a coronary artery bypass graft (CABG) and the patient was ready to receive it, and the date the patient received a planned CABG
Interpretation

50th percentile means a time period that typical patients have to wait to receive care.

90th percentile means that provinces could treat 90% of patients within that time period.

Description
The number of days a patient waited, between the date when the patient and the appropriate physician agreed to a coronary artery bypass graft (CABG) and the patient was ready to receive it, and the date the patient received a planned CABG
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).

Measures:

Wait times are obtained by calculating

1. The number of days that half the patients in the sample received the surgery and half are still waiting (50th percentile)

2. The number of days that 90% of patients in the sample received the surgery and 10% are still waiting (90th percentile)

Unit of Analysis: Client or patient

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.

<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 understand access to care and to know how provinces are performing in terms of providing access to services for patients.

Interpretation

50th percentile means a time period that typical patients have to wait to receive care.

90th percentile means that provinces could treat 90% of patients within that time period.

Targets/Benchmarks

The pan-Canadian benchmark specifies surgery within 2 to 26 weeks (14 to 182 days), depending on how urgently care is needed. As there is a lack of comparability in urgency levels, provinces reported the percentage of patients treated within six months until 2011. Given that the longest benchmark does not truly reflect the experiences of patients who need urgent care, this measure will no longer be reported for 2012 and onward.

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/bypass).

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/bypass).

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.
