Understanding barriers and outcomes of unspecified (non-directed altruistic) kidney donation from both professionals and patients perspectives: research protocol for a national multicentre mixed-methods prospective cohort study

Introduction

Living donation accounts for over one-third of all kidney transplants taking place in the UK.¹ The concept of anonymously donating a kidney to a stranger (non-directed altruistic or unspecified kidney donation (UKD)) remains uncomfortable for some clinicians, principally due to concerns about the motivations and long-term physical and psychological outcomes in this donor group.

Aims

The research programme aims to provide a comprehensive assessment of the unspecified donor programme in the UK. It aims to identify reasons for variations in practice across centres, explore outcomes for donors and ascertain barriers and facilitators to UKD, as well as assess the economic implications of unspecified donation.

Methods

The research programme will adopt a mixed-methods approach to assessing UKD nationally using focus groups, interviews and questionnaires. Two study populations will be investigated. The first will include transplant professionals involved in unspecified kidney donation. The second will include a 5-year prospective cohort of individuals who present to any of the 23 UK transplant centres as a potential unspecified living kidney donor. Physical and psychological outcomes will be followed up to 1 year following donation or withdrawal from the donation process. A matched sample of specified donors (those donating to someone they know) will be recruited as a control group. Further qualitative work consisting of interviews will be performed on a purposive sample of unspecified donors from both groups (those who do and do not donate).

Dissemination

The findings will be reported to NHS Blood and Transplant and the British Transplant Society with a view to developing national guidelines and a protocol for the management of those presenting for unspecified donation.
