Registry data: For the ‘no systematic screening’ scenario the number of elective and emergency operations per year was estimated using data from Finnish national registries, according to the current situation in Finland. The data on operations was based on the National Hospital Discharge Register (HDR), which includes details on all hospital visits and episodes in Finland. The estimate of ruptured AAAs was based on the number of emergency operations and the AAA-related deaths from the National Cause of death –register and HDR. The ICD10 –codes used were I71.3, I71.4, and I71.8.

Modelling: The decision-analytic modelling was used to simulate how the number of elective and emergency operations would change as a result of a screening programme.

Amounts of resources used in AAA screening are also described in the Organisational domain; please see RC-ORG3, RC-ORG7, RC-ORG8, RC-ORG9 and RC-ORG16. This result card estimates the amounts of resources used when delivering AAA screening but the estimation is based on decision-analytic modelling done using Finnish register-based data.

Table 3. Estimated difference in amounts of resources needed for population-based screening compared with no population-based AAA screening, per cohort of 100 000 people. Figures in ‘population-based screening’ are estimates based on the decision-analytic modelling, and figures in ‘no population-based AAA screening’ are based on registry data from Finland.

The amounts of resources needed for population-based AAA screening differ markedly from the corresponding figures for current practice, ie. no population-based AAA screening. The estimated numbers of operations for both alternatives are presented in Table 3 for a cohort of 100 000 people. The numbers of operations in the table should not be seen as the total number of AAA operations per year, because the total number would also include patients that belong to older cohorts whose AAA had been detected in the screening (or any patients whose AAA is ruptured).
