The number of days patients waited, from the date the order/requisition was received to the date that patients received CT scans
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 patients waited, from the date the order/requisition was received to the date that patients received CT scans
Calculation: Description

The data set contains the following provincial and national wait time information for the first two quarters of the fiscal year (April–September):

Measures:

Wait times are obtained by calculating

1. The number of days half of 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)

Inclusions:
1. Those age 18 and older

<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

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.

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/ctscan).

Trending Issues

Since 2008, an increasing number of provinces have adapted to the standard methodology to increase the comparability of results. When comparing several years of data for a particular province, attention should be given to the exceptions. For more information, visit the Wait Times website and view provincial exceptions (http://waittimes.cihi.ca/All/ctscan).
