Objective: Opportunities for timely recognition of chronic limb-threatening ischaemia (CLTI) within primary care, such as performing cardiovascular assessment during clinical consultation, are possibly being missed. This study aimed to investigate for potential missed opportunities within primary care. Methods: This was a population based cohort study, using the UK's Clinical Practice Research Datalink (CPRD). Patients undergoing a major amputation for CLTI between 1 January 2000 and 31 December 2016 were included. Primary care consultation and patient clinical data within the one year period prior to amputation were extracted from the CPRD. Dates of last primary care consultation and cardiovascular assessment prior to amputation were evaluated. Timings of latest cardiovascular assessments were stratified into recent (7-90 days before amputation) and late (> 91 days). Results: In total, 3 260 patients were included. In the year prior to amputation, patients attended a median of 19 (range 9-32) primary care consultations; however, prescription of secondary preventive medications was poor (antiplatelet 49.7%; lipid lowering agent 40.7%). Overall, 2 175 patients (66.7%) attended a primary care consultation 7-30 days before their amputation. However, only 416 (12.8%) underwent a cardiovascular assessment within this period, with 2 073 (63.6%) undergoing no assessment within 90 days of their amputation. Of these 2 073 patients, 1 230 (59.3%) had a primary care consultation 7-30 days before their procedure. Patients undergoing late assessment were younger (p = .003), with higher systolic (p = .008) and diastolic (p = .001) blood pressures than those undergoing recent assessment. Differences were also observed between assessment timings by deprivation (p = .003) and ethnicity (p = .006). Conclusion: Missed opportunities for timely recognition potentially exist and may be related to age, deprivation, and ethnicity. Further work is required to investigate these factors, as well as individual amputations to identify the causes precipitating amputation. Greater emphasis on the medical management of peripheral arterial disease and identifying cardiovascular risk factors in patients who may not fit the at risk stereotype, are also required.
