Chapter Five: RESULTS<br />

5.1 Classification <strong>of</strong> colonoscopies within EndoPro database<br />

In the time period <strong>of</strong> May 16 th , 2000 through April 1 st , 2004, a total <strong>of</strong> 23,527<br />

colonoscopies were conducted in the Calgary Health Region <strong>an</strong>d recorded in EndoPro.<br />

As shown in section 4.3, a computerized <strong>an</strong>d a m<strong>an</strong>ual search were conducted to classify<br />

procedures:<br />

• Definite IBD n = 2,875<br />

• Possible IBD n = 2,469<br />

• Non-IBD n = 18,181<br />

As shown in Figure 1, indication fields were more helpful to screen procedures <strong>for</strong> a<br />

definite diagnosis <strong>of</strong> IBD. Moreover, as expected there was considerable overlap among<br />

indication, findings, <strong>an</strong>d impression screenings. Of 2,875 definite IBD, procedures 292<br />

had findings or <strong>an</strong> impression <strong>of</strong> IBD without <strong>an</strong>y indication <strong>of</strong> IBD, these might<br />

represent procedures <strong>for</strong> incident cases.<br />
