Primary
| Measure | Time frame |
|---|---|
| 1. Structure and processes within the vascular service measured using a novel online questionnaire weekly until the end of data collection 2. Document all vascular surgery and interventional procedures performed using an online purpose-built data collection tool (per centre/patient) at baseline, time/date of surgery, date of discharge from hospital, three, six, and twelve months: 2.1. Type of procedure performed 2.2. Time taken from presentation to the surgical team to intervention 2.3. Mode of referral (primary vs. secondary care) 2.4. Site of surgery – hub or spoke hospital 2.5. Imaging modalities used and timings 2.6. Emergency classification i.e. urgent/emergency/elective 2.7. Operative technique(s) and device(s) used 2.8. Mode(s) of anaesthesia (local, regional, general, locoregional, other) 2.9. Whether suspected or confirmed COVID-19 positive (+ve) at time of surgery, COVID-19 +ve after surgery, or COVID-19 negative (-ve) 2.10. Documentation of changes to usual practice for this specific procedure as per surgeon’s standard protocol (type of procedure, type of anaesthetic, post-procedural destination) 3. Management of all referred urgent vascular cases using the online survey, focusing on: 3.1. Chronic Limb Threatening Ischaemia (CLTI): 3.1.1. Decision to discharge/admit/refer to a "hot"/emergency clinic 3.1.2. Decision for endovascular or open surgery first 3.1.3. Decision for best medical therapy or palliation or primary amputation 3.2. Carotid disease: 3.2.1. Number of patients managed with best medical therapy (BMT) 3.2.2. Modifications to the indication and decision for carotid endarterectomy (CEA) 3.2.3. Delays to treatment due to lack of | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Collected after surgery has been performed at three, six, and twelve months using patient records: 1.1. Re-admission 1.2. Re-intervention 1.3. All-cause mortality 1.4. Operation-specific morbidity 1.5. Morbidity 1.6. [If COVID-19 +ve] - respiratory outcome, admission to intensive care unit 2. Condition-specific outcomes at 3, 6 months and 1 year: 2.1. CLTI - limb salvage, amputation free survival, all-cause mortality 2.2. Carotid disease - ipsilateral stroke rate, any stroke rate, all-cause mortality 2.3. AAA - aneurysm-related mortality, all-cause mortality 2.4. AAS - complication rate including ruptures, all-cause mortality | — |
