Patterns of use of flexible sigmoidoscopy, colonoscopy and gastroscopy: Sample

gastroscopiesRecords on 120,224 individuals who underwent 161,591 colonoscopies, 162,000 individuals who underwent 242,163 gastroscopies and 84,689 individuals who underwent 104,914 flexible sigmoidoscopies from January 1, 1994 to March 31, 2002 were provided by Alberta Health and Wellness. Postal code of residence was missing for 388 (0.24%), 746 (0.31%) and 398 (0.38%) of those undergoing a colonoscopy, gastroscopy or flexible sigmoidoscopy, respectively.

The postal code of residence at the date of the procedure was outside of Alberta for 200 (0.12%), 258 (0.11%) and 109 (0.10%) of those undergoing a colonoscopy, gastroscopy and flexible sigmoidoscopy, respectively. Those with a missing or out-ofprovince postal code were excluded from further analysis.

From 1994 to 2001, the number of gastroscopies performed annually increased by 39%, from 24,463 to 34,060. The annual number of colonoscopies increased by 147%, from 12,495 to 30,818. The number of flexible sigmoidoscopies increased by 6%, from 11,7565 to 12,541. The annual provincial age-sex adjusted colonoscopy, flexible sigmoidoscopy and gastroscopy rates from 1994 to 2001 and estimated rates for 2002 are shown in Table 1 and Figure 2.

Provincial age-sex adjusted endoscopy rates

Figure 2) Provincial age-sex adjusted endoscopy rates, 1994 to 2002. There has been a marked increase in colonoscopy rates. The rates for gastroscopy increased somewhat between 1994 and 2001. Flexible sigmoidoscopy (Flex Sig) rates remained stable between 1994 and 2000, but have declined more recently. Rates for 2002 are estimated based on data from January to March 2002
