| Potential criterion | Explanation |
|---|---|
| Importance to patients, service users or the population | Well conducted research comparing different surveillance intervals and imaging modalities, would enable more specific and individually tailored treatment choices to be made in the future. |
| Relevance to NICE guidance | Medium priority: the research would fill relevant gaps in the evidence base, but it is possible to make generic recommendations for amending postoperative surveillance based on clinical expertise. |
| Current evidence base | No evidence was found that explored which surveillance intervals or tailored surveillance approaches were most effective in monitoring postoperative complications, further aneurysm expansion and aneurysm rupture after EVAR or open repair of an abdominal aortic aneurysm. |
| Equality | No specific equality concerns are relevant to this research recommendation. |
| Feasibility | The clinical data to produce a systematic review or populate a health economic model in this area is already available, and therefore no further primary data collection is likely to be necessary in order to conduct an economic evaluation. |
