Eye donation from palliative and hospice care contexts: The EDiPPPP mixed-methods study

Abstract

Background: Over 2 million people in the United Kingdom are living with sight loss with costs to the United Kingdom economy reported as £4.34 billion annually. Conditions that lead to sight loss and impaired vision can be treated if eye tissue is available for corneal transplantation, reconstructive surgery and research into eye diseases. Supply of eye tissue (only available via eye donation) is currently insufficient to meet demand; therefore, new routes are needed. Hospice and hospital-based Palliative Care Services have been reported as potential donation sources of this tissue. Objectives: To: (1) scope the size and clinical characteristics of the potential eye donation population from research sites; (2) map the donation climate of each research site; (3) identify factors that enable or challenge service providers to consider the option of eye donation from a local and national perspective;(4) identify service users’ views regarding the option of eye donation and the propriety of discussing eye donation; and (5) develop and pilot an empirically based intervention designed to change behaviours in relation to eye donation. Design: A 36-month mixed-methods, multicentre study undertaking three work packages. Settings: Three hospice care and three hospital-based palliative care services situated in the North, Midlands and the South of England (one service of each type per region).Participants: Work package 1 – 105 service providers. Work package 2 – 62 service users, and 156service providers in the national survey. Work package 3 – 21 expert consultees (patient and public involvement, cross discipline).Data sources: Scoping review, retrospective note review, qualitative interviews/focus groups, participant observation, secondary analysis of primary data, national survey, transparent expert consultation. Results: Potential: The retrospective notes review demonstrated that of 1199 deceased patients’ notes,553 (46%) patients met the criteria for eye donation (56%, n = 337 in hospice care service settings and36%, n = 216 in hospital palliative care service). Practice: Less than 4% of all cases agreed as eligible for donation had been approached or referred for eye donation. Eye donation is not currently an embedded practice at local and national levels. Perceptions: Service providers were motivated to discuss eye donation but lacked opportunity and capability. Service users were willing and able to hold conversations about eye donation but were not aware of the option and had not had the option discussed with them. Preferences: Service users wanted to be offered the option of eye donation, and service providers wanted bespoke education and training related to eye donation. Evaluation of the developed intervention STEPS – Support Toolkit for Eye donation in Palliative care Settings will follow implementation of the full intervention (expected to begin in October 2022). Limitations: Due to the significant impact of the COVID-19 pandemic on clinical sites, partner organisations and national service providers, only two elements of the developed intervention have been pilot tested for proof of concept and the response rate to the national survey was low (8%).Conclusions: Significant potential exists for eye donation from hospice care and hospital palliative care services; however, individual and organisational behaviour as well as information system-based changes are needed to maximise this potential.
