Brief summary

The PERCEIVE (PrEdiction of Risk and Communication of outcomE followIng major lower limb amputation - a collaboratiVE study) study aims to explore how decisions about major lower limb amputations are made by patients and healthcare professionals.

Detailed description

This study will look in detail at major lower limb amputation risk perception, communication and decision-making, both from a patient/family and a surgeon/clinician point of view. The investigators will audio-record 10-15 consultations between surgeons and patients, examining the communication and decision-making process, and conduct individual interviews with 10-15 patients and 10-15 healthcare professionals. Patients will be interviewed at two time points: firstly as soon as possible after they discuss the possibility of leg amputation with a surgeon, and secondly around six months later. The investigators will identify what is important to patients, what information they need to make an informed decision and how best to communicate that information. Interviews with surgeons, anaesthetists and specialist physiotherapists will explore how they estimate risks and outcomes of amputation surgery, and how they communicate this to patients. Finally, the investigators will combine all this information together and discuss our findings with groups of patients and healthcare professionals, to identify key areas around amputation decision-making that can be improved and how best to further examine those areas.
