National Bowel Cancer Screening Program: PI 05a-Adenoma detection rate
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||National Bowel Cancer Screening Program adenoma detection rate|
|Synonymous names:||NBCSP adenoma detection rate|
|Registration status:||Health, Standard 06/09/2018|
The proportion of people who returned a valid National Bowel Cancer Screening Program (NBCSP) screening test in a defined 12-month period who were diagnosed with an adenoma within the defined period or the following 12 months.
Adenomas are benign growths that have the potential to become cancerous, and their removal is likely to lower the risk of future colorectal cancer. Therefore, the adenoma detection rate (particularly the detection of advanced adenomas) is one measure of the effectiveness of the program.
This indicator is defined to calculate the proportion of people who screened and had an adenoma detected, not the number of adenomas found per 100 diagnostic assessments. Therefore, it should not be used as a measure of the quality of diagnostic assessment.
To reduce the effect of any lag time between invitation, positive screen, diagnostic assessment and histopathology, this indicator includes all those who screened in the defined period, not all those invited in the defined period (who had a positive screen).
