Study 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.

Read the 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.

Study population

Participants are eligible for the study if they meet all of the following inclusion criteria and none of the exclusion criteria apply. All queries about participant eligibility should be directed to the Qualitative Researcher. We will purposively sample participants from up to four participating NHS Health Boards / Trusts in Wales and England. We will aim to include 8-10 surgeons, 1-3 anaesthetists and 1-3 specialist physiotherapists from several Health Boards / Trusts. We will purposively sample patients for inclusion in the audio-recorded consultations and interviews to ensure our sample has variation in terms of gender, age, MLLA type (above knee/below knee/no amputation) and Health Board / Trust.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Any patient aged 18 years old or over with chronic limb threatening ischaemia or diabetic foot disease for whom major lower limb amputation is considered or discussed
  • Vascular surgeons / anaesthetists / specialist physiotherapists involved in, or supporting major lower limb amputation decision making

Exclusion criteria

Exclusion Criteria:

  • Patients under 18 years old
  • Patients undergoing major lower limb amputation for other causes (e.g. trauma or cancer)
  • Any patient/healthcare professional unable or unwilling to provide . Some patients undergoing emergency major lower limb amputation will have insufficient time to give informed consent
  • Potential participants with an insufficient understanding of English or Welsh to be able to provide informed consent
  • Potential participants unable to complete an interview in English
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2020 to primary completion in Dec 2022, 26 months.

Of 138 non-industry observational studies under Peripheral Arterial Disease, half reached primary completion within 40 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 116. This study's 26 months is below that.

Counting every sponsor, half of 196 studies reached it within 36 months; a quarter within 22 and three quarters within 73.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 29, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
