Hospital clinicians' perceptions and experiences of care pathways for chronic limb‐threatening ischaemia: a qualitative study

Abstract

Abstract Background Chronic limb‐threatening ischaemia (CLTI) is a condition associated with significant risks of lower limb loss and mortality, which increase with delays in management. Guidance recommends urgent referral and assessment, but delays are evident at every stage of the CLTI patient pathway. This study uses qualitative methods to explore hospital clinicians' experiences and perceptions of the existing CLTI pathway. Methods A qualitative interview study was conducted. Semi‐structured interviews were undertaken with 13 clinicians involved in the assessment of patients referred to hospital with suspected CLTI, identified via purposive sampling from English vascular surgery units. Clinicians included podiatrists, vascular specialist nurses and doctors. Reflexive thematic analysis was performed on the data from a critical realist position. Results The need for speed was the single overarching theme identified. Four linked underlying themes were also identified; 1. Vascular surgery as the poor relation (compared to cancer and other specialties), with a sub‐theme of CLTI being a challenging diagnosis. 2. Some patients are more equal than others, with sub‐themes of diabetes vs. non‐diabetes, hub vs. spoke and frailty vs. non‐frail. 3. Life in the National Health Service (NHS) is tough, with sub‐themes of lack of resource and we're all under pressure. 4. Non‐surgeons can help. Conclusions The underlying themes generated from the rich interview data describe barriers to timely referral, assessment and management of CLTI, as well as the utility of non‐surgical roles such as podiatrists and vascular specialist nurses as a potential solution for delays. The overarching theme of the need for speed highlights the meaning given to adverse consequences of delays in management of CLTI by clinicians involved in its assessment. Future improvement projects aimed at the CLTI pathway should take these findings into account.
